ABSTRACT

Objective: Halitosis is the offensive odor emanated by the oral and nasal cavities and perceived by the individual and/or by other people. Halitosis is a symptom that directly impacts on the social aspects of an individual's life and may be a sign for a systemic disorder in some cases. Material and Methods: A search was conducted on the literature in order to gather the main aspects about halitosis and make a review about the main features necessary to the clinical practice when a professional deals with a patient with halitosis. Results: The information was summarized and discussed with a focus on what clinicians should be aware of when dealing with a patient with halitosis. Conclusion: Halitosis is a prevalent symptom that affects approximately 25% of the individuals. Its classification takes into consideration the origin of the compounds producing the malodor. The diagnosis must take into consideration the various etiological possibilities before defining the treatment. The treatment must be focused on the cause and since there is a wide range of possible causes, halitosis needs a multidisciplinary approach (AU)


Objetivo: Halitose é um cheiro ofensivo expelido pela cavidade bucal e pela cavidade nasal e percebido pelo indivíduo e/ou pelas outras pessoas. A halitose é um sintoma que impacta diretamente aspectos sociais da vida de um indivíduo e pode ser um sinal de alguma desordem sistêmica em alguns casos. Material e Métodos: Uma busca foi feita na literatura para reunir os principais aspectos da halitose e conduzir uma revisão sobre as principais características necessárias à prática clínica quando um profissional lida com um paciente com a queixa de halitose. Resultados: A informação disponível foi sumarizada e discutida com foco naquilo que um clínico deve estar atento quando lida com um paciente com a queixa de halitose presente. Conclusão: A halitose é um sintoma prevalente que afeta aproximadamente 25% dos indivíduos. Sua classificação leva em consideração a origem dos compostos que produzem o mau hálito. O diagnóstico deve levar em conta as várias etiologias possíveis antes de definir um tratamento. O tratamento deve ser focado na causa e, como há uma ampla variedade de possíveis causas, a halitose é um sintoma que precisa de uma abordagem multidisciplina (AU)

ABSTRACT

In recent years, studies investigating psychological states such as happiness in individuals' health have increased. Aim: This study investigated a possible association between self-perceived oral health and happiness in university students. Methods: This cross-sectional study was performed in a cohort of university students who entered in the 2016 academic year at the Federal University of Pelotas, located in southern Brazil. Data were collected using a self-administered questionnaire, including demographic and socioeconomic characteristics, psychosocial traits, and oral health-related questions. Happiness was measured through a question accompanied by the Faces Scale of Andrews and Whitey. Poisson regression models with robust variance were used to assess the association between the exposure variables (oral health measures) and the outcome (happiness). Results: The prevalence of happiness was 48.6%. A significant association between happiness and oral health, including satisfaction with dental appearance (PR 1.86; 95% CI 1.73-2.01), oral health-related to quality of life (PR 1.19; 95% CI 1.09-1.31), and halitosis (PR 1.10; 95% CI 1.01-1.20), was found. Conclusion: Individuals who reported dissatisfaction with dental appearance, an impact on oral health-related to quality of life, and halitosis perceived themselves as unhappy

ABSTRACT

Introduction: violacein is a natural purple pigment produced by environmental bacteria that presents antimicrobial activity, particularly against Gram-positive bacteria. Intraoral halitosis (IOH) is a condition defined by the unpleasant odor emanating from the mouth, whose main source are volatile sulfur compounds, produced by Gram-negative oral bacteria on the tongue coating. In IOH treatment, antimicrobials have been indicated as chemical adjuncts, including natural products. Objective: thus, this study tested the antimicrobial activity of a violacein extract on key IOH-related bacteria (Porphyromonas gingivalis, Porphyromonas endodontalis, Fusobacterium nucleatum, Prevotella intermedia, Solobacterium moorei). Materials and Methods: bacteria were cultured in fastidious anaerobe blood agar in anaerobiosis, and 109 cells/ml suspensions were plated. Crude extract of violacein obtained from Chromobacterium violaceum was diluted in a 25% ethanol aqueous solution to 8, 4, 2, 1, 0.5 and 0.25 mg/ml. Using the disk agar diffusion method, 10 µl aliquots of each dilution were deposited on the seeded plates. Chlorohexidine (0.1%) and 25% ethanol solution were used as controls. Plates were incubated in anaerobiosis at 37°C for 72h, and the inhibition halos were recorded. Results: although chlorhexidine showed higher inhibition halos than the violacein extract, most species were inhibited at 4 and 8 mg/ml concentrations (p<0.05). P. gingivalis followed by F. nucleatum were the most affected species in relation to the other bacteria, although statistical significance was only reached for P. gingivalis (p<0.05). Conclusion: crude violacein extract from C. violaceum demonstrated antimicrobial activity against IOH-associated oral bacteria, being a potential antimicrobial to be studied as an adjunct in the control of IOH.


Introdução: a violaceína é um pigmento roxo natural produzido por bactérias ambientais que apresenta ação antimicrobiana, particularmente contra bactérias Gram-positivas. A halitose intraoral (HIO) é uma condição definida pelo odor desagradável que emana da boca, cuja principal fonte são os compostos sulfurados voláteis produzidos por bactérias Gram-negativas da saburra lingual. No tratamento da HIO, antimicrobianos têm sido indicados como adjuvantes, incluindo produtos naturais. Objetivo: assim, este estudo avaliou o potencial antimicrobiano de um extrato de violaceína em patógenos-chave da HIO (Porphyromonas gingivalis, Porphyromonas endodontalis, Fusobacterium nucleatum, Prevotella intermedia, Solobacterium moorei). Materiais e Métodos: bactérias foram cultivadas em meio ágar sangue para fastidiosos, em anaerobiose, e suspensões de 109 células/ml foram semeadas. O extrato bruto de violaceína obtido de Chromobacterium violaceum foi diluído em solução aquosa com 25% de etanol nas concentrações de 8, 4, 2, 1, 0,5 e 0,25 mg/ml. Através do método de disco difusão, 10 µl de cada diluição foram depositados nas placas semeadas. A clorexidina (0,1%) e a solução etanólica a 25% foram usadas como controles. As placas foram incubadas em anaerobiose a 37°C por 72h, e os halos de inibição foram registrados. Resultados: embora a clorexidina tenha apresentado os maiores halos de inibição do do que o extrato, a maioria das espécies foi inibida nas concentrações de 4 e 8 mg/ml (p<0,05). P. gingivalis e F. nucleatum foram as espécies mais afetadas em relação às outras bactérias, porém só foi observada significância estatística para P. gingivalis (p<0,05). Conclusão: o extrato bruto de violaceína de C. violaceum demonstrou atividade antimicrobiana contra bactérias orais associadas a HIO, sendo um potencial antimicrobiano a ser estudado como adjuvante no controle da HIO.

ABSTRACT

RESUMEN Introducción: El hábito de fumar está asociado a una gran variedad de cambios perjudiciales en la cavidad bucal, pues altera su microambiente y lo predispone para que se presenten diversas afecciones. Objetivo: Determinar la posible relación del hábito de fumar con las afecciones bucales en adolescentes. Método: Se realizó un estudio observacional en adolescentes del Centro Mixto «Pepito Tey» de San Diego del Valle, Cifuentes, en el período comprendido entre septiembre de 2016 y octubre de 2018. La población de estudio, conformada por 208 adolescentes, se organizó en dos estratos: grupo estudio y grupo control. Se seleccionaron dos muestras probabilísticas por muestreo aleatorio simple (60 adolescentes en cada grupo). Resultados: Predominaron adolescentes de 12 años, fumadores leves, del sexo masculino, con inicio del hábito entre 14-15 años y práctica de este hábito de menos de 6 meses. Se asociaron al hábito de fumar: la caries dental, la enfermedad periodontal, las manchas dentales, las lesiones de la mucosa bucal y la halitosis. Conclusiones: Predominaron adolescentes fumadores masculinos de 12 años. La gran mayoría de los fumadores fueron clasificados como leves, con inicio del hábito entre los 14-15 años de edad, y con práctica desde hace menos de seis meses. Existió asociación significativa entre el hábito de fumar y las afecciones bucales (enfermedad periodontal, caries dental, mancha dental, halitosis y lesión de la mucosa bucal).


ABSTRACT Introduction: smoking is associated with a wide variety of harmful changes in the oral cavity, since it alters its microenvironment and predisposes it to the occurrence of various conditions. Objective: to determine the possible relationship between smoking and oral conditions in adolescents. Method: an observational study was carried out in adolescents from "Pepito Tey" Mixed Center, in San Diego del Valle, Cifuentes between September 2016 and October 2018. The study population, made up of 208 adolescents, was organized into two strata: study group and control ones. Two probabilistic samples were selected by simple random sampling (60 adolescents in each group). Results: 12-year-old male light smokers, who started smoking between 14 and 15 years of age and practiced this habit for less than 6 months, predominated. Dental caries, periodontal disease, dental stains, oral mucosal lesions and halitosis were associated with smoking. Conclusions: 12-year-old male adolescent smokers predominated. Most smokers were classified as light, started smoking between 14 and 15 years of age and practiced this habit for less than 6 months. There was a significant association between smoking and oral conditions (periodontal disease, dental caries, dental stains, halitosis and oral mucosal lesions).

ABSTRACT

Abstract Objective: To determine the correlation between levels of methyl mercaptan (CH3SH) hydrogen sulfide (H2S), the proportion of Prevotella intermedia (Pi), and matrix metalloproteinase-8 (MMP-8) gene expression levels in periodontitis patients accompanied by halitosis. Material and Methods: Samples were obtained from gingival crevicular fluid (GCF) in the deepest pocket and by swabbing in the tongue coating area in patients with periodontitis presenting with halitosis (n = 23) and healthy subjects as controls (n = 7). The values of CH3SH and H2S were obtained using Oral Chroma. The proportion of Pi and MMP-8 expression levels were evaluated using PCR-RT. All the result was statistically analyzed using SPSS software. Results: The levels of CH3SH and H2S in participants with PD ≥ 6 mm showed a robust negative correlation with the proportion of P. intermedia in GCF and tongue coating. No statistically significant association was detected between CH3SH and H2S levels and MMP-8 expression levels (p>0.05). Conclusion: There is no association between CH3SH and H2S levels, the proportion of P. intermedia, and MMP-8 expression in patients with periodontitis accompanied by halitosis (AU).

ABSTRACT

Nuestra cavidad bucal cuenta con características particulares como ecosistema y microbiota. Este hábitat de microorganismos es uno de los más diversos de cualquier comunidad microbiana asociada a los humanos, y además cumple ciertas funciones en los procesos biológicos y digestivos del hospedante. Aunque muchos de estos microorganismos residentes aportan beneficios, en condiciones de sinergia y exacerbación, el predominio de algunos géneros puede influir en el desarrollo de enfermedades periodontales. Se realizó una investigación cuantitativa, exploratoria, descriptiva y transversal en el de Centro de Salud de Latacunga, provincia de Cotopaxi, en Ecuador, en mujeres cuya edad oscilaba entre 45 y 55 años. Se estableció una relación lineal negativa entre la edad y el pH salival, es decir, que al aumentar la edad aumentó la acidez bucal de las pacientes. De manera similar, el pH salival influyó inversamente en la disponibilidad microbiótica, pues en las cavidades bucales más ácidas el índice de detección fue más alto en 18/25 microorganismos. Las proporciones de afecciones en la salud bucodental encontradas en las pacientes como caries (96%), gingivitis (67%), halitosis (78%) y xerostomía (56%), indican la no exclusión y superposición de las mismas, pudiendo presentarse patologías combinadas en un mismo paciente, haciendo necesario explorar de qué manera los niveles de pH y la diversidad microbiótica oral encontrados se interrelacionan, y a su vez como estas nosologías podrían tener determinantes similares(AU)


Our oral cavity has particular characteristics such as ecosystem and microbiota. This habitat of microorganisms is one of the most diverse of any microbial community associated with humans, and also fulfills certain functions in the biological and digestive processes of the host. Although many of these resident microorganisms provide benefits, under conditions of synergy and exacerbation, the predominance of some genera can influence the development of periodontal diseases. A quantitative, exploratory, descriptive and cross-sectional investigation was carried out in the Latacunga Health Center, Cotopaxi province, Ecuador, in women whose age ranged between 45 and 55 years. A negative linear relationship was established between age and salivary pH, that is, with increasing age the oral acidity of the patients increased. Similarly, salivary pH inversely influenced microbiotic availability, since in the more acidic oral cavities the detection rate was higher in 18/25 microorganisms. The proportions of conditions in oral health found in patients such as caries (96%), gingivitis (67%), halitosis (78%) and xerostomia (56%), indicate their non-exclusion and overlap, and pathologies may occur combined in the same patient, making it necessary to explore how the pH levels and oral microbiotic diversity found are interrelated, and in turn, how these nosologies could have similar determinants(AU)

ABSTRACT

Resumen La halitosis es considerada como una condición anómala frecuente en la salud bucal y se define como un olor desagradable que emite la cavidad oral, nariz, vías respiratorias o aparato digestivo. Objetivo: Determinar la prevalencia de halitosis y su relación con los factores asociados como: higiene oral, caries, placa lingual, tipo de respiración, edad y sexo en niños de 5 a 12 años que asisten a la Escuela Giordano Bruno, de la Provincia de Pichincha - Ecuador. Materiales y métodos: Estudio observacional, descriptivo, transversal realizado en una población de 178 estudiantes de 5 a 12 años, la muestra fue de 122 niños seleccionados mediante un muestreo probabilístico. Se solicitó el consentimiento informado para participar en el estudio. La prevalencia de halitosis se evaluó con un monitor que detecta compuestos volátiles de sulfuro. Los factores asociados se midieron por medio del IHOS, el índice de lengua saburral de Winkel, la prueba con el espejo bucal y el índice ceo-d y CPO-D. Los datos se analizaron con la prueba de Chi cuadrado con un valor de significación de 0,05 y un Análisis de Regresión Logística Binaria. Resultados: La prevalencia de halitosis fue del 50% en los niños y se relacionó con saburralingual, higiene bucal, edad y sexo (p<0,05), pero no hubo asociación entre la halitosis, el tipo de respiración y la presencia de caries dental. Los niños que presentan saburra lingual tienen 177 veces mayor riesgo de presentar halitosis mientras que los que muestran una higiene bucal regular tienen 205 veces más riesgo de presentar halitosis. Conclusión: La prevalencia de halitosis en niños es alta y los principales factores de riesgo son la saburra lingual y la higiene bucal regular.


Abstract Halitosis is considered a frequent anomaly in oral health that is defined as an unpleasant odor that emits from the oral cavity, nose, respiratory tract or digestive system. Objective: To determine the prevalence of halitosis and its relationship with associated factors such as: oral hygiene, tooth decay, tongue plaque, type of breathing, age and sex in children aged 5 to 12 years who attend the Giordano Bruno School of the Province of Pichincha - Ecuador. Materials and methods: Observational, descriptive, cross-sectional study carried out in a population of 178 students aged 5 to 12 years, the sample consisted of 122 children selected through probability sampling. Informed consent was requested to participate in the study. The prevalence of halitosis was evaluated with a monitor that detects volatile sulfur compounds and the associated factors were measured by means of the IHOS, the Winkel coated tongue index, the oral mirror test and the ceo-d and CPO-D index. The data were analyzed with the Chi square test with a significance value of 0.05 and a Binary Logistic Regression Analysis. Results: The prevalence of halitosis was 50% in children and it was related to tongue coating, oral hygiene, age, and sex (p <0.05), there was no association between halitosis, type of respiration and the presence of dental caries. Children with tongue coating have a 177 times greater risk of halitosis, while children with regular oral hygiene have a 205 times greater risk of halitosis. Conclusion: The prevalence of halitosis in children is high and the main risk factors are tongue coating and regular oral hygiene.

ABSTRACT

Mood disorders such as stress and depression can promote alterations of several hormones Aim: The present study aimed to evaluate if symptoms of depression and stress are associated with halitosis. The hypothesis is that halitosis is associated with stress and depression symptoms. Methods: All university students' entrants in the Federal University of Pelotas (UFPel) were invited to participate. Self-reported halitosis was measured using a visual analog scale. Students were also asked about the presence of halitosis perceived by close individuals. The stress level was measured using a modified version of the Perceived Stress Scale and symptoms of depression were screened by Patient Health Questionnaire-2. Poisson Regression Models were performed. Results: Of a total of 2,058 students who participated in the study, only 16% of them have reported not having any degree of halitosis and 17.6% were informed of closed individuals having halitosis. After adjustments, stress and depression symptoms remained associated with halitosis selfreported. Individuals from the higher stressed quartile presented higher scores of halitosis (RR 1.37 CI95% [1.24­1.53]). Students who presented depressive symptoms showed higher scores of self-perceived halitosis (RR 1.20 CI95% [1.10­1.32]). When the association of stress and halitosis reported by close individuals was tested, symptoms of depression lost the association in the adjusted model, while individuals from the highest quartile from stress remained associated (PR 1.36 CI95% [1.02­1.81]). Conclusion: Halitosis was associated with stress even after control for oral health and socioeconomic variables

ABSTRACT

Objective: to review the literature on the relationship between oral health and bariatric surgery in obese individuals. Methods: articles published until March 2021 were searched in the Medline/PubMed, LILACS, BBO, and Web of Science databases. The search used a combination of descriptors related to the words: obesity, bariatric surgery, and oral health. Results: one hundred thirty-five studies were identified in the database search. Of these, 47 were included in this review. The oral changes investigated in the literature for individuals who underwent bariatric surgery were dental caries, tooth wear/erosion, hypersensitivity, periodontal disease, hyposalivation, halitosis, and changes in mastication and oral soft tissue. The evaluated articles showed methodological controversy regarding the study design, follow-up period, sample size, and assessed clinical parameters, which complicated the comparison of studies. Final considerations: there is no consensus in the literature regarding the relationship between oral health and bariatric surgery in obese individuals. Further prospective cohort studies should be conducted to investigate this association better.(AU)


Objetivo: revisar a literatura sobre a relação entre saúde bucal e cirurgia bariátrica em indivíduos obesos. Métodos: foi realizada uma busca de estudos publicados até março de 2021 nas bases de dados Medline/PubMed, LILACS, BBO e Web of Science. Foi utilizada uma combinação de descritores relacionada às palavras: obesidade, cirurgia bariátrica e saúde bucal. Resultados: foram identificados 135 estudos nas bases de dados pesquisadas. Desses, 47 estudos foram incluídos nesta revisão. As alterações bucais investigadas em indivíduos que realizaram cirurgia bariátrica apresentadas na literatura foram: cárie dentária, desgaste dentário/erosão dentária, hipersensibilidade, doença periodontal, hipossalivação, halitose, alterações da função mastigatória e alterações no tecido mole bucal. Os estudos avaliados mostraram controvérsia metodológica em relação a: tipo de desenho de estudo, tempo de seguimento, tamanho da amostra e parâmetros clínicos avaliados, fato que dificultou comparar os estudos. Considerações finais: não há consenso na literatura sobre a relação entre saúde bucal e cirurgia bariátrica em indivíduos obesos. Mais estudos de coorte prospectivos devem ser realizados para estudar melhor essa associação.(AU)

ABSTRACT

Com a implantodontia, muitos problemas relacionados aos tratamentos reabilitadores puderem ser solucionados. Quando um paciente perde um elemento dentário, remove-se terminações nervosas que diminuem a função táctil naquela região. A halitose é um fator comum em próteses sobre implantes, devido a maior dificuldade de higienização. O objetivo do presente estudo foi avaliar a sensibilidade e halitose de 48 pacientes (n=48), em quatro grupos distintos: Grupo 1 (próteses fixas unitárias); Grupo 2 (próteses fixas múltiplas); Grupo 3 (prótese tipo overdenture); Grupo 4 (próteses fixas do tipo protocolo). A aferição da halitose nos pacientes será por meio de um halímetro (FitScan Breath Checker ­ Tanita, Japan) e a função somatossensorial nos tecidos moles periimplantares através do teste psicofísico de sensação de toque leve (LTS) utilizando monofilamentos de von frey (Aesthesio® - Exacta). Foram realizadas as mensurações em 4 períodos distintos: no momento da colocação dos cicatrizadores (T1), 30 dias após a instalação dos cicatrizadores (T2), no momento da instalação da prótese (T3) e 30 dias após a instalação da prótese (T4). Após os dados coletados, foi realizada análise estatística e comparativa entre os grupos. Foi possível observar que a interação entre os fatores tempo, condição e tipo de prótese interferiram de forma significativa nos valores médios da sensação ao toque utilizando monofilamentos de von frey (P = 0,001). Foi possível verificar que houve associação entre o nível de halitose e o tempo de análise para o uso de prótese protocolo e para prótese overdenture. Porém, o mesmo não ocorreu para prótese unitária ou múltipla esplintada. No grupo protocolo (P = 0,002) e no grupo overdenture (P = 0,002), a contagem que apresentou achado estatisticamente significativo foi odor forte ou intenso no momento da reabertura e 30 dias após a instalação da prótese. Quanto à sensibilidade ao toque, todos os grupos obtiveram resultados significativos do aumento da sensibilidade ao toque durante e após a instalação da prótese se comparados ao inicial(AU)


With implant dentistry, many problems related to rehabilitative treatments can be solved. When a patient loses a tooth element, nerve endings that decrease tactile function in that region are removed. Halitosis is a common factor in implant prostheses, due to greater difficulty in cleaning. The aim of the present study was to evaluate the sensitivity and halitosis of 48 patients (n = 48), in four distinct groups: Group 1 (unitary fixed prostheses); Group 2 (multiple fixed prostheses); Group 3 (overdenture type prosthesis); Group 4 (fixed protocol type prostheses). The measurement of halitosis in patients will be through a Halimeter (FitScan Breath Checker - Tanita, Japan) and the so-matosensory function in peri-implant soft tissues through the psychophysical test of light touch (LTS) using von frey monofilaments (Aesthesio ® - Exact). Measurements were taken in 4 different periods: at the time of placement of the healers (T1), 30 days after the installation of the healers (T2), at the time of installation of the prosthesis (T3) and 30 days after the installation of the prosthesis (T4) . After the collected data, a statistical and comparative analysis was performed between the groups. It was possible to observe that an interaction between the factors time, condition and type of prosthesis significantly interfered in the mean values of the sensation to touch using von frey monofilaments (P = 0.001). It was possible to verify that there was an association between the level of halitosis and the analysis time for the use of protocol prosthesis and for overdenture prosthesis. However, the same did not occur for single or multiple splinted prostheses. Without group protocol (P = 0.002) and without group overdenture (P = 0.002), the count that presented a statistically significant finding was strong or intense odor at the time of reopening and 30 days after prosthesis installation. As for sensitivity to touch, all groups obtained results obtained from increased sensitivity to touch during and after installation of the prosthesis compared to the initial one(AU)

ABSTRACT

Objetivo: avaliar quais as possíveis causas e quais são os fatores associados ao surgimento da halitose. Métodos: foi realizada uma revisão nos bancos de dados PubMed e SciELO, utilizando os descritores e sinônimos MeSH organizados em lógica booleana: 'Halitosis' AND 'Risk Factors' OR 'Association' OR 'Etiologies', com as seguintes etapas: identificação dos artigos, triagem, elegibilidade e inclusão. Apenas artigos publicados entre os anos de 2015-2020, ensaios clínicos randomizados, estudos transversais ou de coorte foram incluídos na revisão. Foram excluídos protocolos de estudos e os artigos que não estavam nos critérios e objetivo desta revisão. Resultados: de 240 artigos encontrados, 22 foram inclusos. Desses, 50% demonstraram que a falta ou a deficiência dos hábitos de higiene oral se relacionam com a halitose. Ainda, 40,9% deles se referem à saburra lingual como um forte fator etiológico e 36,4% demonstram que a doença periodontal está diretamente associada com o mau hálito. Além disso, em relação a outras condições locais e sistêmicas, xerostomia (13,6%), doença gastrointestinal e refluxo laringofaríngeo (9,1%), rinite e diabetes (4,5%) também demonstraram associação. Considerações finais: a halitose pode estar associada com higiene bucal, saburra lingual, doença periodontal, alguns hábitos e quadros sistêmicos.(AU)


Objective: to evaluate the possible causes and what are the factors associated with the onset of halitosis. Methods: a review was performed in the PubMed and SciELO databases, using the descriptors and synonyms MeSH organized in Boolean logic: 'Halitosis' AND 'Risk Factors' OR 'Association' OR 'Etiologies', with the following steps: identification of articles, screening, eligibility and inclusion. Only articles published between 2015- 2020; randomized clinical trials; cross-sectional or cohort studies were included in the review. Study protocols and articles that were not in the criteria and objective of this review were excluded. Results: Of 240 articles found, 22 were included. Of those, 50% showed that the lack or deficiency of oral hygiene habits are related to halitosis. Furthermore, 40.9% of them refer to tongue coating as a strong etiological factor and 36.4% demonstrate that periodontal disease is directly associated with bad breath. Moreover, in relation to other local and systemic conditions, xerostomia (13.6%), gastrointestinal disease and laryngeal reflux (9.1%), rhinitis and diabetes (4.5%) also demonstrated an association. Final considerations: Halitosis may be associated with oral hygiene, lingualcoating, periodontal disease, some habits and systemic conditions.(AU)

ABSTRACT

RESUMO Introdução: A halitose é um sinal da presença de mau cheiro ofensivo ao olfato humano, geralmente é provocada pela falta de higiene ou estilo de vida e afeta milhares de pessoas em todo o mundo. Objetivo: Realizar uma revisão de literatura a respeito da etiologia, diagnóstico e tratamento da halitose buscando proporcionar um maior embasamento cientifico com informações atualizadas para os profissionais da área. Métodos: O estudo caracterizou-se por uma busca de artigos na base de dados eletrônicos PubMed, Lilacs, Google Acadêmico e Scielo publicados entre 2014 e 2019, em inglês, português e espanhol. Foram consultados 52 trabalhos, destes, 28 foram selecionados após uma criteriosa filtragem. Análise e integração das informações: Diversas etiologias advindas da cavidade bucal podem provocar a halitose. Existem vários exames complementares para auxílio diagnóstico da halitose, tais como testes sialométricos, organoléptico e a análise de presença de saburra para o diagnóstico. Há diversos protocolos instituídos para o tratamento da halitose, desde procedimentos preventivos a curativos. Conclusão: No que concerne a etiologia, a halitose pode ocorrer por fatores fisiológicos ou patológicos; 90 porcento dos casos tem como origem a cavidade oral, podendo estar associada ao biofilme dentário, cárie, língua saburrosa, próteses mal adaptadas e cicatrização tecidual.

ABSTRACT Introduction: Oral halitosis or malodor is offensive to the human sense of smell. It is often the result of poor hygiene or lifestyle and affects thousands of people worldwide. Objective: Conduct a literature review about the etiology, diagnosis and treatment of halitosis with the purpose of contributing a broader scientific basis of updated information for professionals in the field. Methods: The study was characterized by a search for papers published in the electronic databases PubMed, Lilacs, Google Scholar and Scielo between 2014 and 2019 in English, Portuguese or Spanish. A total 52 papers were consulted, of which 28 were selected after careful filtering. Data analysis and integration: Halitosis may be due to a variety of oral cavity etiologies. Several complementary tests are available which help diagnose halitosis, e.g. sialometric tests, organoleptic tests and analysis of the presence of saburra for the diagnosis. Several protocols have been implemented for the treatment of halitosis. These range from preventive to healing procedures. Conclusions: The etiology of halitosis may be due to physiological or pathological factors. Although 90 percent of the cases originate in the oral cavity and may be associated with dental biofilm, caries, tongue saburra, ill-fitted prostheses or tissue scarring, diagnosis should be based on careful clinical examination. Using questionnaires to gather information such as frequency, duration, number of times it appears on the same day, habits and medications will help elucidate the case. Successful treatment depends on the diagnosis and implementation of a cause-and-effect therapy and a rational multidisciplinary approach which is essential to obtain positive outcomes and improve oral health as well as its individual and social effects(AU)

ABSTRACT

RESUMEN Halitosis es la presencia de un olor desagradable que emana de la cavidad oral. La etiología de este mal olor es multifactorial, existiendo causas no orales, orales y extraorales. Los compuestos volátiles sulfurados (CVS): sulfuro de hidrógeno y metilmercaptano son los elementos prominentes del mal olor. Intraoralmente, existe una correlación significativa entre las concentraciones de CVS y bacterias periodontopatogénicas. En pacientes sin enfermedad periodontal el mal olor se origina principalmente de la cobertura del dorso de la lengua por lo que la limpieza o raspado de ésta es un método efectivo para prevenir o disminuir la halitosis. Existen múltiples opciones químicas para el abordaje del mal aliento que dependerán del origen y grado de severidad. Este artículo revisa el origen y los tratamientos tanto mecánicos como químicos que se tienen disponibles.


ABSTRACT Halitosis is the presence of an unpleasant smell that emanates from the oral cavity. The etiology of halitosis is multifactorial, existing non oral, oral and extraoral causes. The volatile sulphur compounds (VSC): hydrogen sulfide and methyl mercaptan are the prominent elements of malodour. Intraorally there is a significant correlation between VSC concentrations and periodontopathogenic bacteria. In patients with no gum disease the halitosis is originated mainly in the dorsal surface of the tongue, so cleaning or brushing it is an effective method to prevent or decrease halitosis. There are multiple chemical options for the treatment of the malodour that will depend on the origin and severity of it. This article reviews the origin and mechanical and chemical treatments that are available.

ABSTRACT

Abstract The present study aimed to validate (cross-culturally adapt and test psychometric properties) the Brazilian version of the Halitosis Associated Life-Quality Test (HALT). A process of translation and cross-cultural adaptation was conducted by a group of dental researchers. The first draft of the Brazilian Portuguese version was pre-tested on a sample of 33 individuals leading up to the final version of the questionnaire. The Brazilian version of the HALT (B-HALT) was applied to 100 individuals with halitosis (organoleptic score ≥ 2) and 100 individuals without halitosis (organoleptic score < 2). Exploratory factor analysis (EFA) was performed to evaluate the dimensionality of B-HALT. Cronbach's alpha (α) and interclass correlation coefficient (ICC) were used to measure its reliability. For convergent validity, Spearman's correlation was conducted between the B-HALT and the organoleptic scores. The discriminant validity was evaluated through the Mann-Whitney and Kruskal-Wallis tests. EFA confirmed the unidimensionality of B-HALT, which has also demonstrated excellent internal consistency (α = 0.96) and test-retest reliability (ICC = 0.93). There was a positive correlation between B-HALT and organoleptic scores (r = 0.33; p < 0.001). B-HALT was able to discriminate between the groups with and without halitosis measured by the organoleptic method (p < 0.001) and self-reported halitosis (p < 0.001). B-HALT has demonstrated to be a reliable and valid tool to evaluate the oral health-related quality of life associated to halitosis in Brazilian adults.

ABSTRACT

OBJECTIVES: This study aimed to determine the accuracy of the Breath-Alert™ portable breath meter (BA) for the detection of halitosis in children and adolescents, considering the organoleptic test (OT) as the gold standard in this assessment. METHODS: A cross-sectional study was conducted on 150 children (aged 6-12 years). OT was performed by three independent examiners on a single occasion, obtaining three scores of 0-5 points on the Rosenberg's organoleptic scale. The median of the three evaluations for each child was used for analysis. BA was used according to the manufacturer's instructions, with breath odor scored from 0-5 points. Scores ≥2 on both tests were considered indicative of halitosis. RESULTS: A total of 26 (17.3%) and 23 (15.3%) children were detected with halitosis on the OT and BA tests, respectively. The sensitivity and specificity of the BA scores for the detection of halitosis were 80.76% and 98.38%, respectively. The positive and negative predictive values for BA were 91.3% and 96.06%, respectively. CONCLUSION: In the present study involving children, who require fast, practical examinations, BA proved to be an auxiliary tool to OT for the detection of halitosis in the practice of pediatric dentistry, demonstrating high sensitivity and specificity.

ABSTRACT

RESUMEN La halitosis es un motivo de consulta frecuente y que puede repercutir de gran manera en la calidad de vida de quien la presenta. Puede dividirse en halitosis genuina, pseudohalitosis y halitofobia. De las halitosis genuinas, cerca del 90% son secundarias a patología de la cavidad oral. En otorrinolaringología, las principales causas responden a tonsilolitiasis, patología rinosinusal y cuerpos extraños nasales. Existen distintos métodos diagnósticos que permiten medir e identificar la halitosis, con sus beneficios y desventajas. Las medidas generales de higiene oral, así como intervenciones específicas deben estar basadas en la evidencia a cargo de un equipo multidisciplinario que permita garantizar mejores resultados.


ABSTRACT Halitosis is a frequent health problem, that can have a huge impact in the quality of life of those affected. It can be classified as genuine halitosis, pseudohalitosis and halitophobia. Of genuine halitosis, approximately 90% is originated from the oral cavity. In otorhinolaryngology, most frequent causes are tonsiloliths, rhinosinusitis and nasal foreign bodies. There are different diagnostic methods, each one with its benefits and disadvantages. General measures of oral hygiene, as specific interventions must be evidence-based in charge of a multidisciplinary team that guarantees better results.

ABSTRACT

ABSTRACT Halitosis is highly prevalent in periodontitis and attributed mainly to the presence of volatile sulfur compounds (VSC), where hydrogen sulfide (H2S) is the chief culprit in the characteristic malodor of periodontitis and thus may play an active role in its pathogenesis. The aim of this study was to evaluate the effect of H2S in the acute, intermediate and chronic immuneinflammatory host response and alveolar bone loss in vivo by using an animal model of induced periodontal disease. Thirtysix rats were divided into 2 groups: test group (n = 18), rats exposed to H2S (NaHS H2S donor molecule) and control group (n = 18), rats treated with saline only (Ctrl). All animals had one of their lower second molars ligated to induce periodontal disease (PD). The sound contralateral molar was used as control (H). Each group was subdivided into 3 (n = 6), according to followup time (3h, 5 days and 14 days). The gingival tissue was used for mRNA expression analysis (IL1, IL6, RANKL, OPG and SOFAT) by realtime PCR and the mandibles were analyzed morphometrically. Data analysis showed that the ligature promoted alveolar bone loss, observed mainly at 14 days, both in the group exposed to H2S and in the Ctrl group. H2S administration did not result in additional bone loss. Gene expression showed a significant increase in IL1, IL6, RANKL and SOFAT only in the CtrlPD group (p<0.05). A significant downregulation in OPG expression was observed over time in the CtrlPD group (p<0.05). In conclusion, H2S had no effect on alveolar bone loss in the absence of a ligature. In the presence of a ligature, however, exposure to H2S had an immunoregulatory effect on the expression of proinflammatory and proresorptive cytokines.


RESUMO A halitose é altamente prevalente na periodontite e é atribuída principalmente à presença de compostos sulforosos voláteis (CSV), sendo o sulfeto de hidrogênio (H2S) o principal gás relacionado ao mau odor e que pode estar envolvido na patogênese da doença periodontal. O objetivo deste estudo foi avaliar o efeito agudo, intermediário e crônico do H2S na resposta imunoinflamatória e na perda óssea alveolar em ratos, com e sem doença periodontal induzida. Trinta e seis ratos foram divididos em 2 grupos: teste (n = 18), ratos expostos ao H2S (NaHS molécula doadora de H2S) e grupo controle (n = 18), ratos tratados apenas com solução salina (Ctrl). Todos os animais tiveram um dos seus segundos molares inferiores submetidos à colocação de uma ligadura para o desenvolvimento da doença periodontal (DP), em comparação com o dente contralateral saudável (H). Cada grupo foi subdividido em 3 (n = 6), de acordo com o tempo de eutanásia (3h, 5 dias e 14 dias). Os tecidos gengivais foram utilizados para a análise da expressão gênica (IL1, IL6, RANKL, OPG e SOFAT) por PCR em tempo real e as mandíbulas foram analisadas morfometricamente. Análise dos dados demonstrou que a ligadura promoveu perda óssea alveolar, observada principalmente aos 14 dias, tanto no grupo exposto ao H2S quanto no grupo Ctrl. A administração de H2S não resultou em perda óssea adicional. A expressão gênica demonstrou aumento significativo de IL1, IL6, RANKL e SOFAT apenas no grupo CtrlPD (p <0,05). Uma significativa regulação negativa na expressão de OPG foi observada ao longo do tempo no grupo CtrlPD (p <0,05). Podese concluir que o H2S não teve efeito adicional na perda óssea alveolar, na ausência de ligadura. Entretanto, na presença de ligadura, a exposição ao H2S teve um efeito imunorregulatório na expressão de citocinas próinflamatórias e próreabsortivas.

ABSTRACT

Hygiene deficiency causes type 1 (oral) halitosis. There are short and long-term studies on the anti-halitosis effect of mouth rinses but less knowledge on their instant effects. The aim of this study was to compare instant and freshness effects of 8 mouth rinses on type 1 halitosis. Ninety self-reported halitosis patients (19-58 y.o., median 31) were randomly divided into 9 groups. Cysteine (20 mM) challenge test was applied to obtain maximum halitosis level in the mouth of each patient. Single use of 8 different mouth rinses (R1-R8) and tap water (R0) were tested on each group (n=10). Afterward, patients were requested to score oral freshness effect of the mouth rinse on a 5-point scale (0, bad; 5, fresh). Minimum halitosis level was obtained by rinsing with 20 mMol ZnCL2. In each step, oral gas (organic, NH3, SO2, H2S, H2) concentrations were quantified by using a portable multi-gas detector (MX6, IndSci, US). The ANOVA or Kruskal Wallis tests were used to compare the quantitative measurements. R3 (Halitosil Zn) mouth rinse was found to be have the highest instant anti-halitosis effect while the R2 (Colgate plax) had the lowest. The sensation of freshness was highest in R7 (Oxyfresh power mouth rinse lemon-mint) and lowest in R8 (Signal expert protection). The freshness effect was not associated with the anti-halitosis effect (r= 0.185, p=0.608). Mouth rinses containing ZnCl2 without alcohol are instantly effective on halitosis. Mouth rinses containing ethyl and other alcohols (including glycol, sorbitol, menthol, eucalyptol, thymol, xylitol and eugenol) were found to be less effective on halitosis.


La deficiencia de higiene causa halitosis tipo 1 (oral). Se han reportado efectos anti-halitosis a corto o largo plazo de los enjuagatorios bucales, pero se desconocen sus efectos instantáneos. El objetivo de este estudio fue comparar el efecto instantáneo y de frescura de 8 enjuagues bucales en la halitosis tipo 1. Noventa pacientes (19-58 años, mediana 31) que reportaron sufrir halitosis se dividieron aleatoriamente en 9 grupos. Se aplicó la prueba de provocación con cisterna (20 mM) para obtener el máximo nivel de halitosis en la boca de cada paciente. El uso individual de 8 enjuagues bucales diferentes (R1-R8) y agua del grifo (R0) se probó en cada grupo (n = 10). Posteriormente, se pidió a los pacientes que puntuaran el efecto de la frescura oral del enjuague bucal en una escala de 5puntos (0, malo; 5, fresco). El nivel mínimo de halitosis se obtuvo con 20 mMol de ZnCL2 enjuague. En cada paso, se cuantificaron las concentraciones de gases orales (orgánicos, NH3, SO2, H2S, H2) mediante el uso de un detector portátil de múltiples gases (MX6, IndSci, EE. UU.)Se encontró que el enjuague bucal R3 (Halitosil Zn) tiene un mayor efecto antihalitosis instantáneo, mientras que el R2 (Colgate plax) fue el más bajo. El sentido de frescura fue mayor en el enjuague bucal R7 (enjuague bucal Oxyfresh power lemon-mint) mientras que fue bajo en R8 (protección experta de Signal). El efecto de frescura no se asoció con el efecto anti-halitosis (r = 0.185, p=0.608). Los enjuagues bucales que contienen ZnCl2 sin alcohol son instantáneamente efectivos en la halitosis. Se encontró que los enjuagues bucales que contenían etil y otros alcoholes (incluidos glicol, sorbitol, mentol, eucaliptol, timol, xilitol y eugenol) son menos efectivos para el control de la halitosis.

ABSTRACT

Objetivos: correlacionar os exames organolépticos (método subjetivo) e a cromatografia gasosa (método objetivo) para diagnóstico conclusivo da halitose e avaliar o comportamento dos compostos sulfurados voláteis (CSVs) durante o manuseio clínico desta patologia. Metodologia: estudo longitudinal com 19 pacientes submetidos ao diagnóstico de halitose, com exames organolépticos (EOt1) e cromatografia gasosa (ECGt1) realizados durante a consulta inicial, com todos os pacientes oriundos do município de Ijuí, Rio Grande do Sul. Todos os 38 exames complementares foram confrontados entre si, por meio do teste estatístico Qui-Quadrado de independência. Para acompanhamento clínico da efetividade do tratamento da halitose e, consequentemente, análise do comportamento dos CSVs, outros quatro exames de cromatografia gasosa (ECGt2, ECGt3, ECGt4 e ECGt5) foram realizados para cada paciente, e todos (95) comparados entre si, pelo teste de Wilcoxon. Resultados: a correlação entre EOt1 e ECGt1 obteve concordância em 78,9% dos casos, indicando forte associação (p = 0,002) entre ambos. Ao avaliar a monitorização dos compostos sulfurados H2S, CH3SH e (CH3)2S, todos envolvidos em alguma fase da gênese da halitose, houve significativa redução de todos os compostos. Conclusões: os exames de cromatografia gasosa (objetivo) e organoléptico (subjetivo) são equivalentes para diagnóstico inicial da halitose, pois apresentaram correlação estatística significante. Em relação à monitorização do tratamento da halitose, a cromatografia gasosa se mostrou eficiente, apresentando altos índices de redução de todos os CSVs. (AU)


Objectives: To correlate organoleptic evaluations (subjective method) and gas chromatography (objective method) for the conclusive diagnosis of halitosis and to examine the behavior of volatile sulfur compounds (VSC) during the clinical management of this pathology. Methodology: Longitudinal study with 19 patients diagnosed with halitosis through organoleptic evaluations (EOt1) and gas chromatography (ECGt1), both applied during the initial appointment. All patients were from the city of Ijuí, located in the state of Rio Grande do Sul, Brazil. All 38 complementary analyses were compared using the chi-square test of independence. Regarding the clinical follow-up on the effectiveness of halitosis treatment, and consequently the analysis of VSC behavior, four other gas chromatography tests (ECGt2, ECGt3, ECGt4, and ECGt5) were conducted with each patient, and all (95) were compared using the Wilcoxon test. Results: The correlation between EOt1 and ECGt1 showed concordance in 78.9% of cases, indicating a strong association (p=0.002). The evaluation of the monitoring of sulfate compounds H2S, CH3SH, and (CH3) 2S, which are all involved in some phase of the halitosis genesis, showed a significant reduction of all compounds. Conclusions: The gas and chromatography and organoleptic tests are equivalent for the initial diagnosis of halitosis because they presented significant statistical correlation. Regarding the monitoring of halitosis treatment, gas chromatography was efficient, presenting high reduction rates of all VSC. (AU)

ABSTRACT

Objective: To perform the transcultural adaptation to Brazil and validation of the Halitosis Associated Life-quality Test (HALT) for use in adolescents. Material and Methods: Students aged 12 to 15 years, of both sexes, with healthy permanent dentition, attending public schools in Piracicaba, Brazil, were selected for this study. The HALT was translated, backtranslated, reviewed by an expert committee and submitted to a pre-test. In the first phase (n = 13), 15% of the sample did not understand items 2, 12 and 15; therefore, these items were reformulated and resubmitted to 13 adolescents. The version with a sociocultural adaptation was self-applied by 56 adolescents (64% females, 13.4 ± 1.0 years), of whom 25 participated in the test-retest. The presence of visible biofilm, gingival bleeding, calculus and tongue coating, was evaluated. Selfperception of halitosis after exhalation/breathing was assessed by a single question. Results: The HALT score ranged from 0 to 62 points (mean = 10.1±13.4) and the floor effect was 5.4%. Internal consistency was excellent (Cronbach's alpha = 0.92) and reproducibility was moderate (Intraclass Correlation Coefficient = 0.59). Individuals with "excessive" tongue coating had a higher HALT score than those with mild and/or moderate coating (p<0.001). Multiple linear regression analysis indicated that only the male sex was related to a higher HALT score (p<0.05). Conclusion: The Brazilian Portuguese version of the HALT was easily understood by adolescents. Those with greater tongue coating accumulation reported more frequently the presence of halitosis, which was only associated to male sex.
