Prevalence of tooth loss, bleeding on probing and malocclusion as oral disease indicators in Costa Rican male adolescents: a cross sectional study / Prevalencia de la pérdida de piezas dentales, del sangrado al sondeo y la maloclusión como indicadores de enfermedades orales en adolescentes varones costarricenses: un estudio transversal

The evidence to characterize oral health during adolescence in Costa Rica is limited. This lack of adequate research makes it difficult to develop appropriate health policies for this subgroup of the population. This is particularly important because adolescence is the period during which good health habits must take root in order to foster good physical and cognitive development. This study aims to determine the prevalence of tooth loss, bleeding on probing and malocclusion in Costa Rican male adolescents at the ''Colegio Técnico Profesional San Agustín'' (St. Augustine's Technical High School) located in the province of Cartago. Data was collected from 428 male adolescents aged 12-22 years in a cross-sectional study during 2019. Prevalence of tooth loss was calculated as the number of individuals having lost at least one tooth. The average number of teeth lost by individuals was also recorded. The bleeding on probing was an indicator used as a proxy parameter for monitoring periodontal health where the presence of bleeding on probing and calculus was also recorded. Malocclusion was measured using the Dental Aesthetic Index (DAI). The results showed that the prevalence of tooth loss, bleeding on probing and malocclusion was of 19%, 70.0% and 98%, respectively. It was also found that 81% of the participants had all their teeth, 11% had lost 1 tooth, 8% had lost more than one tooth of which 0.5% had lost more than 5 teeth. Considering a general classification of periodontal problems based on bleeding on probing and presence of calculus, the prevalence of periodontal problems increases to 92%. Regarding the DAI, the category identifying a very severe malocclusion was the most prevalent in the sample (88%). It is alarming the high prevalence of tooth loss, bleeding on probing, and malocclusions in a sample of Costa Rican male adolescents, compared to similar studies in other countries. The overarching conclusion of this study is that oral diseases represent an important health problem that urgently need proper public health action.

La evidencia para caracterizar la salud bucal durante la adolescencia en Costa Rica es limitada. Esta falta de investigación adecuada dificulta el desarrollo de políticas de salud convenientes para este subgrupo de la población. Esto es particularmente importante porque la adolescencia es el período durante el cual se deben arraigar buenos hábitos de salud para fomentar un buen desarrollo físico y cognitivo. Este estudio tiene como objetivo determinar la prevalencia de pérdida de piezas dentales, sangrado al sondeo y maloclusión en adolescentes varones costarricenses del Colegio Técnico Profesional San Agustín ubicado en la provincia de Cartago. Se recopilaron datos de 428 adolescentes varones de 12 a 22 años en un estudio transversal durante 2019. La prevalencia de pérdida de piezas dentales se calculó como el número de individuos que habían perdido al menos una pieza dental. También se registró el número promedio de dientes perdidos por individuos. El sangrado al sondeo fue un indicador utilizado como parámetro para el seguimiento de la salud periodontal donde también se registró la presencia de sangrado al sondeo y cálculo dental. La maloclusión se midió utilizando el Índice Estético Dental (DAI, por sus siglas en inglés). Los resultados mostraron que la prevalencia de pérdida de piezas dentales, sangrado al sondeo y maloclusión fue del 19%, 70,0% y 98%, respectivamente. También se encontró que el 81% de los participantes tenían todos sus dientes, el 11% había perdido 1 pieza dental, el 8% había perdido más de una pieza dental, de los cuales el 0,5% había perdido más de 5 piezas dentales. Considerando una clasificación general de problemas periodontales basada en sangrado al sondeo y presencia de cálculo, la prevalencia de problemas periodontales aumenta al 92%. En cuanto al DAI, la categoría que identifica una maloclusión muy severa fue la más prevalente en la muestra (88%). Es alarmante la alta prevalencia de pérdida de piezas dentales, sangrado al sondeo y maloclusiones en una muestra de adolescentes varones costarricenses, en comparación con estudios similares en otros países. La conclusión general de este estudio es que las enfermedades bucodentales representan un importante problema de salud que necesita urgentemente una acción adecuada de salud pública.

Cambios en parámetros masticatorios con prótesis parcial removible para dientes posteriores perdidos / Changes in masticatory parameters with removable partial dentures for missing posterior teeth

Introducción: el reemplazo de dientes perdidos aspira a mejorar la función masticatoria. Aunque hay diferentes opciones para ello, la conveniencia de la prótesis parcial removible (PPR) es su bajo costo. Objetivo: comparar el desempeño masticatorio (DM) después de 20 ciclos masticatorios y al umbral de la deglución (UD) en adultos de 50 a 70 años con dientes posteriores perdidos (DPP), con/sin PPR; y los ciclos hasta la deglución. Material y métodos: estudio transversal en 35 adultos con dientes anteriores y PPR bien ajustadas y utilizadas para comer. El lado de prueba fue el lado con más DPP. El DM se evaluó después de 20 ciclos y al UD utilizando un alimento prueba artificial (Optosil Comfort®) con/sin la PPR en orden aleatorizado. Las partículas se tamizaron para determinar el tamaño medio de partícula (TMP) como medida del DM. Los ciclos se contaron visualmente. Estadística descriptiva y comparaciones con SPSS-v23. Resultados: hubo diferencias significativas (p ≤ 0.05) al masticar con/sin PPR. El TMP fue más pequeño (mejor DM) con la PPR después de 20 ciclos y al UD (3.9 vs 4.4 mm y 3.2 vs 4.2 mm). Los ciclos para llegar al UD disminuyeron con la PPR (40 vs 47). Conclusión: a pesar de una mejora limitada de la función masticatoria, las PPR ayudan a preparar los alimentos en partículas más pequeñas antes de deglutirlas. La mejoría en DM con PPR es de 24% al UD, realizando menos ciclos antes de deglutir sus alimentos (AU)

Introduction: replacement of missing teeth should improve masticatory function. Although there are different options removable partial dentures (RPD) are used due to their lower cost. Objective: to compare masticatory performance (MP) after 20 chewing-cycles and swallowing-threshold (ST) in 50-70 year-old adults with missing posterior teeth (MPT) with and without their cast-metal RPD; chewing cycles until swallowing were also compared. Material and methods: 35 adults participated in this cross-sectional study. Subjects with anterior teeth and welladjusted RPDs, used for eating were included. The side with more MPT was selected as the test side. MP was evaluated after 20 cycles and ST using an artificial test-food (Optosil Comfort®) with/without the RPD (subject-own-control) (randomized order). Chewed particles were sieved to determine medium-particle-size (MPS) as a measure of MP. Chewing cycles were visually counted. Descriptive statistics and comparisons were run with SPSS v23. Results: there were significant differences (p ≤ 0.05) for all parameters when chewing with/without the RPD. MPS was smaller (better MP) with the RPD (3.9 vs 4.4 mm and 3.2 vs 4.2 mm) after 20 cycles and ST respectively. Cycles required to reach ST were less when chewing with the denture (40 vs 47). Conclusion: despite a limited improvement of masticatory function RPDs help patients prepare their food into smaller particles before swallowing. Improvement in MP with RPDs for patients with MPT is 24% at ST and they perform fewer chewing cycles before swallowing food (AU)

Multivariable analysis of tooth loss in subjects with severe periodontitis over 4-year natural progression / 北京大学学报(医学版)

OBJECTIVE@#To evaluate the characteristics of severe periodontitis with various number of tooth loss during 4-year natural progression, and to analyze the factors related to higher rate of tooth loss.@*METHODS@#A total of 217 patients aged 15 to 44 years with severe periodontitis were included, who participated in a 4-year natural progression research. Data obtained from questionnaire survey, clinical examination and radiographic measurement. Tooth loss during 4-year natural progression was evaluated. The baseline periodontal disease related and caries related factors were calculated, including number of teeth with bone loss > 50%, number of missing molars, number of teeth with widened periodontal ligament space (WPDL), number of teeth with periapical lesions and etc. Characteristics of populations with various number of tooth loss and the related factors that affected higher rate of tooth loss were analyzed.@*RESULTS@#In 4 years of natural progression, 103 teeth were lost, and annual tooth loss per person was 0.12±0.38. Nine patients lost 3 or more teeth. Thirty-four patients lost 1 or 2 teeth, and 174 patients were absent of tooth loss. Molars were mostly frequent to lose, and canines presented a minimum loss. The number of teeth with WPDL, with periapical lesions, with intrabony defects, with probing depth (PD)≥7 mm, with PD≥5 mm, with clinical attachment loss≥5 mm, with bone loss > 50% and with bone loss > 65% were positively correlated to number of tooth loss. Results from orderly multivariate Logistic regression showd that the number of teeth with bone loss > 50% OR=1.550), baseline number of molars lost (OR=1.774), number of teeth with WPDL (1 to 2: OR=1.415; ≥3: OR=13.105), number of teeth with periapical lesions (1 to 2: OR=4.393; ≥3: OR=9.526) and number of teeth with caries/residual roots (OR=3.028) were significant risk factors related to higher likelihood of tooth loss and multiple tooth loss.@*CONCLUSION@#In 4 years of natural progression, the number of teeth with bone loss > 50%, baseline number of missing molars, number of teeth with WPDL, baseline number of teeth with periapical lesions and number of teeth with caries/residual roots were significantly related to higher risk of tooth loss and multiple tooth loss among Chinese young and middle-aged patients with severe periodontitis in rural areas.

Treatment of a patient with class I malocclusion with moderate crowding and missing first molar: A case report

@#The most common occlusal feature of Class I malocclusion is crowding. Crowded and irregular teeth occur in a majority of the population and are the most common complication in adults. This is a case report of a 21-year-old woman with moderate crowding and a missing lower left first molar. The first permanent molars are sometimes unnoticed by the child or their parents and bring a risk of caries to the first permanent molar. Caries in the first molars that persist without any treatment will give a poor prognosis. Treatment was performed using a fixed orthodontic appliance with the extraction of the two upper and one lower first premolars.

Exploration of the motivations in the adherence of patients to periodontal maintenance therapy / Exploración de las motivaciones en la adherencia de los pacientes en la mantención periodontal

Introduction: Although it has been shown that the supportive periodontal therapy (SPT) is essential to maintain the results obtained by periodontal therapy, patient adherence to SPT is not usually satisfactory (4). The objective of this research is to explore the motivations in the adherence to periodontal maintenance of patients treated at Universidad Viña del Mar (UVM) during the year 2020. Material and Methods: A study based on the qualitative paradigm was carried out using a design based on discourse analysis through semi-structured interviews. A sample size of 10 participants was consolidated, by obtaining with them the saturation of data collected and of 4 main dimensions. Each interview was transcribed ad verbatim and later analyzed through the Atlas.ti 9 Software. Results: Four main categories or dimensions were created: Motivations of the patients to produce a change in their oral health; Information that the patients have regarding their oral health; Oral hygiene habits acquired after periodontal treatment; Situations that prevent adherence to periodontal treatment. Conclusion: The main motivations of patients to adhere to supportive periodontal therapy are related to the education and information they acquire in the first phase of periodontal treatment. Observing the changes during treatment, improving oral health, improving aesthetics and functionality, are other important motivations, as well as the patients' fear of losing their teeth and the desire to educate their family.

Introducción: Aunque se ha demostrado que la fase de mantención periodontal (TPS) es esencial para mantener los resultados obtenidos por la terapia periodontal, la adherencia del paciente a la TPS no es, en su mayoría, satisfactoria (4). El objetivo de esta investigación es explorar las motivaciones de los pacientes en la adherencia a la mantención periodontal, atendidos en la Universidad Viña del Mar (UVM), durante el año 2020. Material y Métodos: Se realizó una investigación basada en el paradigma cualitativo por medio de un diseño en base al análisis de discursos a través de entrevistas semiestructuradas. Se consolidó un tamaño muestral de 10 participantes, al obtener con ellos la saturación de datos recolectados y de 4 dimensiones principales, cada entrevista fue transcrita ad verbatim y posteriormente analizadas a través del Software Atlas.ti 9. Resultados: Se generaron cuatro categorías o dimensiones principales: Motivaciones del paciente para generar un cambio en su salud oral, Información que posee el paciente respecto a su salud oral, Hábitos de higiene oral adquiridos posterior al tratamiento periodontal y Situaciones que impiden la adherencia al tratamiento periodontal. Conclusión: Las motivaciones principales que presentan los pacientes para adherirse a la fase de mantención periodontal, están relacionadas con la educación e información que adquieren en la primera fase del tratamiento periodontal. Observar los cambios durante el tratamiento, adquirir salud oral, mejorar la estética y funcionalidad, son otras motivaciones de importancia, así como el miedo que presenta el paciente de perder sus dientes y las ganas de querer educar a su familia.

Autotransplante dentário como ferramenta de tratamento para perdas precoces de molares / Dental self transplantation as a treatment tool for early molar loss / Auto trasplante dental como herramienta de tratamiento para la pérdida molar temprana

O transplante dentário autógeno é um procedimento cirúrgico que consiste na transposição de um elemento dentário do seu alvéolo para um outro, em um mesmo indivíduo. Esta abordagem é indicada para substituir elementos com prognóstico desfavorável ou reabilitar áreas edêntulas. O objetivo deste trabalho é apresentar as vantagens do transplante dentário autógeno frente a perdas dentárias precoces e os critérios necessários para indicação do mesmo, por meio de um relato de caso clínico no qual, uma paciente do gênero feminino, 16 anos foi submetida ao transplante do elemento 48 para o alvéolo do 47 por motivos de lesão cariosa com extensa destruição coronária com impossibilidade de tratamento clínico restaurador. Em acompanhamento pós-operatório de 01 ano os resultados demostraram continuidade do desenvolvimento radicular do elemento transplantado em seu novo alvéolo, estando este, sem mobilidade, livre de lesões periodontais e/ou endodônticas. Desta forma, conclui-se que as vantagens do transplante dentário autógeno incluem a possibilidade de reabilitação dentária de forma natural, imediata e de baixo custo comparado a tratamentos como implantes e próteses. E este método quando indicado corretamente e realizado sob os devidos cuidados pode alcançar excelentes resultados funcionais e estéticos, sendo uma opção viável para reabilitação de perdas dentárias precoces...

The Autogenous dental transplantation is a surgical procedure that consists of the transposition of a dental element from its socket to another, in the same individual. This approach is indicated to replace elements with an unfavorable prognosis or to rehabilitate edentulous areas. The objective of this paper is to present the advantages of autogenous dental transplantation against early tooth loss and the necessary criteria for its indication, through a clinical case report in which a 16-year-old female patient underwent transplantation element 48 for the alveolus of the 47 due to carious lesions with extensive coronary destruction with impossibility of restorative clinical treatment. In a 01-year postoperative follow-up, the results showed continuity of root development of the transplanted element in its new alveolus, which is without mobility, free from periodontal and/or endodontic lesions. Thus, it is concluded that the advantages of autogenous dental transplantation include the possibility of natural, immediate and low-cost dental rehabilitation compared to treatments such as implants and prostheses. And this method, when correctly indicated and performed with due care, can achieve excellent functional and esthetic results, being a viable option for the rehabilitation of early tooth loss... (AU)

The association between sleep disturbances and tooth loss among post-stroke patients / Prevalência de edentulismo e distúrbios de sono após acidente vascular cerebral

ABSTRACT Background: Loss of teeth has been associated with neurological and sleep disorders. It is considered to be a predictor of stroke and leads to modifications of airway patency and predisposition to obstructive sleep apnea. Objective: To investigate sleep quality, risk of obstructive sleep apnea and excessive sleepiness among post-stroke patients with tooth loss attending the Neurovascular Clinic of the Federal University of São Paulo. Methods: The prevalence rates of different types of stroke were assessed among 130 patients with different degrees of tooth loss, along with the presence of sleep disturbances, risk of obstructive sleep apnea and excessive daytime sleepiness. Results: The prevalence of ischemic stroke was 94.6%, with either no significant disability or slight disability. Our sample had poor sleep quality, and a high risk of obstructive sleep apnea, but without excessive daytime sleepiness. Half of our sample had lost between 9 and 31 teeth, and more than 25% had edentulism. The majority used full removable dental prostheses, and more than half of these individuals slept without removing the prosthesis. Conclusions: We found high prevalence of poor sleep quality and high risk of obstructive sleep apnea among post-stroke patients with tooth loss. This indicates the need for further studies on treating and preventing sleep disturbances in stroke patients with tooth loss.

RESUMO Antecedentes: A perda de dentes tem sido associada a distúrbios neurológicos e do sono. É considerada um preditor de acidente vascular cerebral (AVC), com modificações na permeabilidade das vias aéreas e predisposição à apneia obstrutiva do sono. Objetivo: Investigar a qualidade do sono, o risco de apneia obstrutiva do sono e a sonolência excessiva em pacientes pós-AVC com perda dentária, atendidos na Clínica Neurovascular da Universidade Federal de São Paulo. Métodos: O estudo avaliou a prevalência de diferentes tipos de AVC em 130 pacientes com diferentes graus de perda dentária e a presença de distúrbios do sono, risco de apneia obstrutiva do sono e sonolência excessiva. Resultados: A prevalência de AVC isquêmico foi de 94,6%, sem deficiência significativa ou deficiência leve. Nossa amostra tinha má qualidade de sono e alto risco de apneia obstrutiva do sono, sem sonolência diurna excessiva. Metade de nossa amostra perdeu entre nove e 31 dentes, e mais de 25% tiveram edentulismo. A maioria usava próteses dentárias totalmente removíveis e, desses pacientes, mais da metade dormia com elas. Conclusões: Encontramos alta prevalência de má qualidade do sono e alto risco de apneia obstrutiva do sono em pacientes pós-AVC com perda dentária. Isso indica a necessidade de mais estudos sobre o tratamento e a prevenção de distúrbios do sono em pacientes com AVC e perda dentária.

Relationship between tooth loss, nutritional status and consumption of macro and micronutrients in elderly people from southern Brazil

Maintaining a functional natural dentition plays an important role in keeping a satisfactory nutritional status. The aim of this study was to evaluate the relationship between oral health conditions determined by the presence of edentulism and the number of missing teeth, nutritional status and consumption of nutrients by the elderly. This cross-sectional study comprised 494 independent elderly of both genders, over 60 years of age, registered at the Brazilian public health service in Londrina, southern Brazil. The data collection included: oral examinations; anthropometric measurements by calculating the Body Mass Index (BMI); analysis of food consumption based on a multiple pass 24-hour dietary recall and a food intake frequency questionnaire; and structured interviews to obtain sociodemographic information. Multiple linear regression, the Fisher's Exact test, chi-square and Mann-Whitney tests, were applied at a 5% significance level. The prevalence of edentulism was 47.3%; this predominated in females, age group from 65 to 74 years, low education level and low/medium economic classification. A larger numberof underweight and fewer number of overweight elderly were recorded among the edentulous versus dentate participants (< 0.0001). Significantly lower consumption of several nutrients, as well as fruit, was recorded among the edentulous group. In particular, carbohydrates, vitamins (B1, B9 and C), and the majority of the minerals studied were associated with a larger number of missing teeth. In conclusion, tooth loss was associated with the food consumption pattern of some macro-and micronutrients and the nutritional status of the Brazilian elderly.

Self-perception of oral health among tertiary-care users: quanti-qualitative analysis with chronic kidney disease patients

Chronic kidney disease (CKD) has become a global public health challenge. The objective of this study was to analyze the relationship between self-perception of oral health and clinical condition among patients with CKD. This isa quanti-qualitative survey conducted in a CKD specialized service. The sample consisted of 60 patients who underwent oral examinations to have their severity of caries (DMFT) and need for dental prosthesis checked. Age, sex, time on dialysis, marital status, skin color, education and pre-existing diseases were also analyzed. Among the kidney patients who agreed to undergo the clinical examinations and showed communication skills, some were selected, and three focus groups were created, with the participation of a moderator and six to 10 kidney patients in each group. Their speeches were processed in the IRAMUTEQ software and analyzed through the similarity analysis and word cloud techniques. As for profile, the patients were aged 60.23 ± 10.87 years old; were male (73.33%); were on dialysis for 41.90 ± 56.57 months; were married (61.67%); were white (76.67%); had incomplete primary education (41.66%); had arterial hypertension (76.67%); had a DMFT index of 22.55 ± 8.39; 43.33% needed an upper complete denture; and 30.00% needed a lower complete denture. The similarity analysis revealed many doubts and uncertainties about current health services, which can be proven by the words 'no' and 'treatment'. The quanti-qualitative analysis showed a high rate of dental loss and the need for complete dentures and suggests inequities in oral health care for chronic kidney disease patients, especially in tertiary care. There was a positive representation regarding oral health, but the lexicographical analyses of the textual corpusconfirmed the self-perception of lack of dental care.

Tooth Loss, Sociodemographic Conditions and Oral Health-Related Quality of Life in the Elderly

Abstract Objective: To verify the association between impacts produced by tooth loss and sociodemographic variables in the oral health-related quality of life (OHRQoL) in the elderly. Material and Methods: This is an analytical cross-sectional study carried out in the municipality of Vitória/ES, Brazil, which sample was composed of 402 older adults. The Oral Health Impact Profile (OHIP-14) was used to measure the individuals' OHRQoL. For data analysis, descriptive and bivariate analyses were performed using the Fisher's exact test and the Mantel-Haenzsel test to assess the effects of combined dimensions. The significance level adopted was 5%. To assess the strength of association between independent variables and dimensions, Odds-Ratio (OR) with 95% confidence interval (CI) was calculated. Results: The prevalence of negative impact on OHRQoL in the elderly was 32.6%. The greatest impact perception was found in individuals with up to 10 years of schooling (p=0.021 and OR=1.602), with need for removable partial dentures (p=0.000 and OR=2.873) and those who did not accept the loss of dental elements (p=0.000 and OR=3.064). Conclusion: Older female adults with socioeconomic class C/D-E, with up to 10 years of schooling, who lost 11 or more teeth, who declared the need for removable partial dentures, suffered greater impacts caused by tooth loss on OHRQoL.

Screening and analysis of prognostic factors of repairing single missing tooth by autotransplantation of teeth / 中华口腔医学杂志

Objective: To screen and analyze the factors affecting the prognosis of replacing single missing tooth by autograft tooth, so as to provide reference for clinical judgment of surgical prognosis. Methods: A total of 176 patients (188 teeth) underwent autotransplantation of teeth in the Department of Oral & Maxillofacial Surgery, School of Stomatology, The Fourth Military Medical University from January 2017 to December 2019, including 85 teeth of males and 103 teeth of females were involved. The age was (33.0±9.8) years (16-65 years). The possible factors affecting the prognosis of replacing single missing tooth by autograft tooth were summarized and grouped, and the clinical and imaging data were recorded and judged. The surgical records and photographic data from the patients' previous medical records were retrospectively analyzed. The survival analysis method was used for statistical analysis to screen out the factors affecting the cumulative survival rate of transplanted teeth. Results: The 5-year cumulative survival rate of 188 transplanted teeth was 88.4%. Univariate Log-Rank analysis showed that age (P<0.001), sex (P=0.008), smoking (P<0.001), position of recipient area (P<0.001), height of alveolar bone in recipient area (P<0.001), time of donor tooth in vitro (P<0.001), use of donor model (P<0.001) and initial stability (P<0.001) were significantly correlated with cumulative survival rate of transplanted teeth. Multivariate Cox proportional hazard regression analysis showed that smoking (β=-2.812, P=0.049), alveolar bone height (β=1.521, P=0.020), donor time (β=-2.001, P=0.019), use of donor model (β=1.666, P=0.034) and initial stability (β=-1.417, P=0.033) were significantly correlated with the cumulative survival rate of transplanted teeth. Conclusions: The prognosis of autogenous tooth transplantation can be predicted by smoking, height of alveolar bone in recipient area, time of donor teeth in vitro, use of donor model and initial stability. Good prognosis of transplanted teeth can be obtained by using donor model during operation, reducing the time of donor teeth in vitro, taking effective methods to restore alveolar bone height, maintaining good initial stability, and good oral health education after operation.

Early loss of primary molar and permanent tooth germ caused by the use of devitalizer during primary molar root canal therapy: Two cases report / 北京大学学报(医学版)

Devitalization has been widely used in the root canal therapy of primary and permanent teeth in China more than ten years ago. With the development of local anesthetic drugs and injection technologies, this treatment method with high potential risks has been gradually abandoned. However, a questionnaire survey targeted all the participants at the 2018 China Pediatric Dentistry Conference showed that the devitalizer utilization proportion was still as high as 38.1% (383/1 005), even though the ratio was much lower than 75.5% (105/139) in 2003. These doctors had pay more attention to tissue burn caused by devitalizer marginal leakage or direct leakage, and know how to identify and handle with devitalizer burn. Devitalizers were usually made of arsenic trioxide, metal arsenic or paraformaldehyde, which have cytotoxicity, allergenicity, mutagenicity, carcinogenicity, and teratogenic effects on animals. Marginal leakage of devitalizers have high risks of causing soft and hard tissue necrosis. Most of the dentists have an understanding of the potential damages of arsenic containing devitalizers, so they will choose parafor maldehyde with relatively less toxicity. Paraformaldehyde has a certain self limitation, and there are few cases reported, so some dentists lack of vigilance. Paraformaldehyde can also causes tissue necrosis if leakage happens, and the treatment methods are similar to that of arsenic containing devitalizers. When handling with devitalizers burn, the necrosed soft and hard tissue, for example gingiva, alveolar bone or teeth that cannot keep, must be completely removed until fresh blood appears, then rinse with large amount of saline and seal with iodoform gauze. This paper described two cases of devitalizer burn during the root canal treatment of primary molars, both of the doctors failed to identify the devitalizer burn symptoms in the early stage, thus didn't do proper treatments immediately after burning. Resulting in the necrosis of large area of gingiva and alveolar bone, loss of primary molars and permanent tooth germs 1-2 months after devitalizer burn. This paper reported these two cases in detail in order to warn dentists the high risks of using any kind of devitalizers, help them learn how to identify and treat devitalizer burn, and remind them to stop using devitalizers as soon as possible.

Indicação de exodontias e fatores associados: estudo transversal na população indígena Kiriri / Recommendation of tooth extraction and associated factors: cross-sectional study in the Kiriri indigenous population

Resumo O objetivo deste artigo foi avaliar a prevalência e os fatores associados à indicação de exodontia em uma população adulta de índios Kiriri do Nordeste do Brasil. 225 indígenas (≥19 anos) foram avaliados. Os critérios de indicação de exodontia adotados foram: dentes com perda de inserção clínica ≥50%, em pelo menos 3 sítios, e, também, raízes residuais. Modelos estatísticos foram utilizados para avaliar associações entre necessidade de exodontia e as variáveis selecionadas. A porcentagem de dentes com indicação de exodontia foi de 4,98%, caracterizando uma média de 1,24 dente por indivíduo. A análise de regressão mostrou associação positiva entre indicação de exodontia e idade ≥35 anos (OR=2,24, 95%IC: 1,13-4,43, p=0,02), renda <R$ 570,00 (OR=3,34, 95%IC: 1,19-9,37, p=0,02) e índice de placa ≥40% (OR=2,38, 95%IC: 1,24-4,56, p=0,01). Uma prevalência de 33% de indivíduos com indicação de um ou mais dentes para exodontia está, principalmente, relacionada aos fatores de risco: idade maior que 35 anos, índice de placa ≥40% e renda inferior a um salário mínimo. Esse estudo reflete tanto a importância da priorização da prevenção em saúde bucal, como a necessidade de ampliação do acesso aos serviços de maior complexidade.

Abstract The scope of this cross-sectional study was to evaluate the prevalence and the associated factors of the recommendation of dental extraction in the adult Kiriri Indigenous population of northeastern Brazil. A total of 225 natives (≥19 years) were evaluated. The extraction criteria were teeth with clinical attachment loss ≥50% in at least 3 sites, and residual roots. Statistical models were used to evaluate associations between the need for dental extraction and selected variables. The percentage of teeth recommended for dental extraction was 4.98%, characterizing a mean of 1.24 tooth per individual. A regression analysis showed that age ≥35 years (OR=2.24, 95%CI: 1.13-4.43, p=0.02), income <R$ 570.00 (OR=3.34, 95%CI: 1.19-9.37, p=0.02) and plaque index ≥40% (OR=2.38, 95%CI: 1.24-4.56, p=0,01) were significantly associated with indication for dental extraction. A prevalence of 33% of subjects with dental extraction recommendation were associated with age older than 35 years, plaque index ≥40% and income less than a minimum wage were related with the recommendation for extraction. This study reflects the importance of prioritizing oral health prevention, as well as the need to expand complex dental services.

Evaluating edentulism and frailty in a group of elderly people treated at the dental clinic of Universidad San Martín de Porres in Lambayeque, Peru / Condiciones de edentulismo y fragilidad en un grupo de personas mayores que acudieron a la clínica odontológica de la Universidad San Martín de Porres de Lambayeque, Perú

Introduction: Dentistry should contribute to achieving healthy aging based on the identification of the well-being and oral health needs of the elderly. Objective: To evaluate the conditions of edentulism and frailty in a group of elderly people treated at the dental clinic of Universidad San Martín de Porres in Lambayeque, Peru, between the years 2016 and 2018. Material and Methods: An observational, descriptive, retrolective, and cross-sectional study was conducted. Two hundred and seven medical records that included an odontogram were randomly selected to identify cases of total or partial edentulism according to the Kennedy classification. The files were assessed with Fried's test to evaluate the conditions of frailty. The association between variables was estimated by means of a significance analysis using the Chi square test. Results: There was a statistically significant difference between edentulism in both jaws and conditions of frailty (p<0.05). An association of edentulism with physical inactivity and weakness was also demonstrated. Additionally, a statistically significant difference between degrees of edentulism was observed regarding poor diet (p<0.05). Conclusion: The absence of teeth in the elderly acts as a risk factor leading to negative changes in diet, weight, and physical activity. These changes may be associated with frailty, as masticatory insufficiency results in a poor diet and subsequent weakness.

Introducción: El aporte de la Odontología debe contribuir a lograr un envejecimiento saludable, basado en la identificación de las necesidades de bienestar y salud bucal de las personas mayores. Objetivo: Evaluar la condición de edentulismo y de fragilidad en un grupo de personas mayores atendidas en la Clínica Odontológica de la Universidad San Martín de Porres de Lambayeque, entre los años 2016 y 2018. Material y Métodos: Se diseñó un estudio observacional, descriptivo, retrolectivo y transversal, seleccionando de manera aleatoria 207 historias clínicas que incluyeron un odontograma para identificar casos de edentulismo total o parcial de acuerdo a la clasificación de Kennedy: mientras que para evaluar las condiciones de fragilidad fueron revisadas las fichas con el test de Fried. Diferencias entre variables fueron evaluadas con un análisis de significancia mediante la prueba Chi cuadrado. Resultado: Se mostró una diferencia estadísticamente significativa entre edentulismo en ambos maxilares y condiciones de fragilidad (p<0,05). Se evidenció además asociación de edentulismo con inactividad física y debilidad; observándose adicionalmente una diferencia estadísticamente significativa entre grados de edentulismo en relación a la mala alimentación (p<0,05). Conclusion: La ausencia de dientes en las personas mayores funge como un factor de riesgo que contribuye a cambios desfavorables en la dieta, el peso y la actividad física, mismos que se asocian con la fragilidad, donde la insuficiencia masticatoria puede conducir a una deficiente alimentación y la consecuente debilidad.

Prevalence of tooth loss and associated factors in institutionalized adolescents: a cross-sectional study / Prevalência de perda dentária e fatores associados em adolescentes institucionalizados: um estudo transversal

Abstract This study aimed to assess the prevalence of tooth loss and associated factors in institutionalized adolescents. This cross-sectional study included 68 male adolescents incarcerated from Socio-Educational Assistance Center (CASE) aged between 15 and 19 years. Questionnaires were applied individually to assess sociodemographical, economical, medical, behavioral and oral health self-perception variables. All present teeth were evaluated by Decay, Missing, Filling (DMF) Index. The prevalence of tooth loss was analyzed in individuals with ≥1 tooth loss. Associations between tooth loss and exposure variables studied were analyzed by Poisson Regression with robust variance estimation. The prevalence of tooth loss was 47.06%. First molars in the mandible and maxilla and central incisor in the maxilla were the most absent teeth. In the multivariate model, number of decayed teeth, and those that reported daily use of medication were associated with higher tooth loss. Besides, tooth loss was associated with decayed tooth and daily use of medication. Oral health promotion and treatment should be implemented in these institutions to reduce the prevalence of dental loss in these adolescents.

Resumo Esse estudo objetivou avaliar a prevalência de perda dentária e fatores associados em adolescentes institucionalizados. Esse estudo transversal incluiu 68 adolescentes do sexo masculino de um Centro de Atendimento Socioeducativo (CASE) com idades entre 15 e 19 anos. Questionários estruturados foram aplicados individualmente para acessar variáveis sociodemográficas, econômicas, médicas, comportamentais e autopercepção de saúde bucal. Todos os dentes presentes foram avaliados pelo Índice de dentes Cariados, Perdidos e Obturados (CPOD). A prevalência de perda dentária foi analisada em indivíduos com ≥1 dente perdido. Associações entre perda dentária e variáveis de exposição foram analisadas por regressão de Poisson com estimativa de variância robusta. A prevalência de perda dentária foi 47,06%. Primeiros molares na mandíbula e maxila e incisivos centrais na maxila foram os dentes mais ausentes. No modelo multivariado, número de dentes cariados esteve associado com perda dentária, e aqueles que faziam uso diário de medicações foram associados a maior perda dentária. Além disso, perda dentária foi associada com cárie dentária e uso diário de medicação. Promoção de saúde bucal e seu tratamento devem ser implementados nessas instituições para reduzir a prevalência de perda dentária nesses adolescentes.

The impacts of oral health-related quality of life of elderly people living at home: a cross-sectional study / Impactos da qualidade de vida relacionada à saúde bucal de idosos em domicílio: estudo transversal

Abstract The scope was to verify the impact of oral and sociodemographic conditions, the dental treatment needs and dental pain, on the quality of life of the elderly. This cross-sectional study was conducted in 15 primary health care areas. A backward multivariate linear regression model was used (p<0.05) with oral health related-quality of life as dependent variable. There were 335 elderly people with predominance of women (56.72%) and aged up to 74 years (59.40%). Those who had up to 8 years of education predominated (87.46%), and those who were still working were the minority (13.43%). Multivariate linear regression (p<0.05) showed association with missing teeth (β=0,12; IC 0,00:0,04; p<0,04) and dental prosthesis needs (β=0,14; IC 0,13:0,81; p<0,01), women (β=0,18; IC 0,23:0,85; p<0,01), less aged (β=-0,12; IC -0,05:0,00; p<0,02), not working (β=-0,15; IC -1,09:-0,20; p<0,01), with dental care need (β=0,24; IC 0,25:0,63; p<0,01) and dental pain (β=0,14; IC 0,10:0,64; p<0,01). Missing teeth, sociodemographic conditions, dental treatment needs and dental pain might impact oral health-related quality of life of elders.

Resumo O objetivo foi verificar o impacto da condição bucal e sociodemográfica, necessidade de tratamento odontológico e dor dentária na qualidade de vida de idosos. Este estudo transversal realizou-se em 15 áreas de cuidados primários de saúde. O modelo de regressão linear multivariado foi utilizado (p <0,05) considerando qualidade de vida como variável dependente. Participaram 335 idosos, predomínio de mulheres (56,72%) com idade até 74 anos (59,40%). Ter até 8 anos de estudo predominou (87,46%) e os que trabalhavam eram minoria (13,43%). A regressão linear multivariada (p <0,05) apresentou associação da qualidade de vida com dentes perdidos (β=0,12; IC 0,00:0,04; p<0,04) e necessidade de próteses (β =0,14; IC 0,13:0,81; p<0,01), com mulheres (β=0,18; IC 0,23:0,85; p<0,01), idosos mais jovens (β=-0,12; IC -0,05:0,00; p<0,02), que não trabalham (β=-0,15; IC -1,09:-0,20; p<0,01), com necessidades de tratamento odontológico (β=0,24; IC 0,25:0,63; p<0,01) e dor dentária (β=0,14; IC 0,10:0,64; p<0,01). Dentes perdidos, aspectos sociodemográficos, necessidade de tratamento odontológico e dor dentária podem impactar a qualidade de vida relacionada à saúde bucal de idosos.

The role of health literacy as a factor associated with tooth loss / O papel da literacia em saúde como fator associado às perdas dentárias

ABSTRACT OBJECTIVE The objective was to analyze the role of health literacy (HL) as a factor associated with tooth loss among users of the Brazilian Health System with chronic non-communicable diseases. METHODS The cross-sectional analytical study was conducted with adult and elderly users chosen at ten Family Health Clinics in a draw in the town of Piracicaba, São Paulo State, Brazil. A questionnaire was applied with sociodemographic data (sex, age, skin color and education), behavioral data (brushing and flossing), determinants in health (type of dental health services and how often) and clinical data (pain). Mouth conditions were collected by intraoral examination of visible dental biofilm and community Pediodontal Index. The systemic clinical conditions (blood glucose, glycated hemoglobin and blood pressure) were extracted from the medical records. The explanatory variable was HL (low, medium and high), measured with the Health Literacy Scale (HLS-14). RESULTS The outcome was tooth loss measured by the index of decayed, missing and filled teeth. Logistic regression was performed using a conceptual model for HL (p < 0.05). For the 238 subjects, the mean age was 62.7 years (± 10.55). Tooth loss was associated with HL in regression models adjusted by type of dental service, dental frequency, and dental floss. In the final model, the factors associated with tooth loss are older age (OR = 1,12; 95%CI: 1,07-1,17), a lower education (OR = 3,43; 95%CI: 1,17-10,10), irregular use of dental floss (OR = 4,58; 95%CI: 1.75 in-7,31), irregular use of dental services (n = 2,60; 95% 1,32-5,12), periodontal pocket (> 4 mm) (n = 0,31; 95%CI: 0,01-0,08), having visible dental biofilm (OR = 7,23; 95%CI: 3,19-16,41) and a higher level of blood sugar (glucose) (n = 1,98; 95%CI: 1.00-3,92). CONCLUSIONS tooth loss was associated with HL when adjusted by health behaviors; when sociodemographic variables and clinical conditions were included, it was less significant. In the final model, behaviors, determinants in health and clinical conditions were risk indicators of tooth loss, showing the multifactorial nature of this phenomenon.

RESUMO OBJETIVO O objetivo foi analisar o papel da Literacia em Saúde (LS) como fator associado às perdas dentárias entre usuários do Sistema Único de Saúde com doenças crônicas não transmissíveis. MÉTODOS O estudo transversal e analítico foi conduzido com usuários adultos e idosos selecionados em dez Unidades de Saúde da Família sorteadas, em Piracicaba - SP, Brasil. Foi aplicado um questionário com dados sociodemográficos (sexo, idade, cor da pele e escolaridade), comportamentais (escovação e uso de fio dental), determinantes em saúde (tipo e frequência de uso de serviço de saúde médico e odontológico) e clínica (dor). As condições bucais foram coletadas por exame intrabucal do biofilme dental visível e Índice Pediodontal Comunitário. As condições clínicas sistêmicas (glicemia, hemoglobina glicada e pressóricas) foram extraídas dos prontuários. A variável explanatória foi a LS (baixa, média e alta), medida pelo Health Literacy Scale (HLS-14). RESULTADOS O desfecho foi à perda dentária medida pelo Índice de dentes permanentes cariados, perdidos e obturados. Foi realizada regressão logística com uso de um modelo conceitual para a LS (p < 0,05). Para os 238 indivíduos, a média de idade foi 62,7 anos (± 10,55). A perda dentária esteve associada à LS nos modelos de regressão ajustados por tipo de serviço odontológico, frequência odontológica e uso de fio dental. No modelo final, a perda dentária teve como fatores associados a maior idade (OR = 1,12; IC95% 1,07-1,17), menor escolaridade (OR = 3,43; IC95% 1,17-10,10), ao uso irregular de fio dental (OR = 4,58; IC95% 1,75-7,31), uso irregular do serviço odontológico (OR = 2,60; IC95% 1,32-5,12), bolsa periodontal (> 4mm) (OR = 0,31; IC95% 0,01-0,08), ter biofilme dental visível (OR = 7,23; IC95% 3,19-16,41) e maior índice de glicemia (OR = 1,98; IC95% 1,00-3,92). CONCLUSÕES A perda dentária esteve associada à LS quando ajustada por comportamentos em saúde, a partir da inclusão das variáveis sociodemográficas e condições clínicas ela perdeu a significância. No modelo final, comportamentos, determinantes em saúde e condições clínicas foram indicadores de risco da perda dentária, demonstrando a multifatorialidade envolvida neste fenômeno.
