Infiltração resinosa em lesões brancas cariosas e não cariosas: relato de casos / Infiltración resinosa em lesiones blancas cariosas y no cariosas: Reporte de Casos / Resinous infiltration in carious and non-carious white lesions: Case Reports

Introdução: O processo de desmineralização proveniente da cárie leva à formação de manchas brancas que são a primeira manifestação visível da doença. Os infiltrantes resinosos surgem como uma alternativa para o tratamento dessas lesões não cavitadas, pois sãoresinas de baixa viscosidade e faz parte dos procedimentos que visam uma odontologia menos invasiva. Objetivo: Este estudo objetiva relatar a experiência clínica no uso de infiltrante resinoso, Icon, em lesões de mancha branca de etiologias cariosa e não cariosa em dois pacientes distintos, insatisfeitos com a estética do seu sorriso. Descrição do caso: Ao exame clínico foi observado nos pacientes com lesões brancas. No primeiro paciente, de 14 anos, verificou-se a presença da atividade de cárie e micro cavitações. Dessa forma, o plano de tratamento perpassou orientação de higiene oral supervisionada, aplicação de verniz fluoretado, Enamelast, semanal, adequação do meio com restaurações em resina, e só então o uso do infiltrante. A segunda paciente, de 11 anos, já possuía saúde bucal adequada e tinha queixa estética devido à lesão branca não cariosa, hipoplasia, cujo plano de tratamento foi à utilização do Icon apenas. Conclusões: Nos dois casos obteve-se melhoria estética considerável com este procedimento microinvasivo. Melhoria na saúde bucal, aliado à devolução da estética, pode ser observada com o uso de infiltrantes resinosos (AU).

Introduction: The process of demineralization resulting from caries leads to the formation of white spots that are the first visible manifestation of the disease. Resin infiltrants appear as an alternative for the treatment of these non-cavitated lesions, since they are low viscosity resins and are part of the procedures that aim at a less invasive dentistry.Objective:This study aims to report the clinical experience in the use of a resin infiltrant, Icon,in white spot lesions of carious and non-carious etiologies in two different patients who were dissatisfied with the esthetics of their smiles.Methodology: On clinical examination, white lesions were observed in both patients. In the first patient,14 years old,the presence of caries activity and micro cavitations was verified. Thus, the treatment plan included supervised oral hygiene guidance, weekly application of fluoride varnish,Enamelast, adaptation of the environment with resin restorations, and, onlythen, the use of the infiltrant, Icon. The second patient, 11 years old,already had adequate oral health and had an esthetic complaint due to a non-carious white lesion, hypoplasia, whose treatment plan consisted of the use of Icon only.Conclusions:In both cases considerable esthetic improvement was obtained with this microinvasive procedure. Improvement in oral health, combined with the return of esthetics, can be observed with the use of resin infiltrants (AU).

Microbiota of dental caries in primary teeth of a Costa Rican Child population / Microbiota de la caries dental en piezas primarias de una población infantil costarricense

Abstract The objective of this research was to identify bacteria present in the microbiota of dentinal carious lesions in primary molars of some Costa Rican pediatric patients. Data were collected from 15 children aged between 4 and 8 years old who attended the Pediatric Dentistry Clinic at the Faculty of Dentistry from the University of Costa Rica (UCR). The inclusion criteria were: infants between 4 and 8 years old who presented cavitated carious lesions in primary teeth, who were actively attended by students at the Faculty of Dentistry from the UCR, and whose parents or legal guardians signed the informed consent to participate in this research. Samples were taken using a sterile spoon, placed in storage vials, and subjected to various conventional and molecular microbial identification techniques, such as Gram stain identification, catalase tests, oxidase, TSI, API 20E, API STAPH, and VITEK 2. Of the 60 bacterial strains subjected to Gram staining, the following was obtained: 28 Gram-positive bacteria and 32 Gram-negative bacteria. The main isolated organisms were species of Staphylococcus epidermidis, Pasteurella pneumotropica/Mannheimia haemolytica, Pantoea spp, and Streptococcus mutans.

Resumen El objetivo de esta investigación fue identificar las bacterias presentes en la microbiota de lesiones cariosas dentinales en molares primarias de pacientes pediátricos costarricenses. Las muestras fueron recolectadas de 15 niños entre los 4 y 8 años que fueron atendidos en la Clínica de Odontopediatría en la Facultad de Odontología de la Universidad de Costa Rica (UCR). Los criterios de inclusión fueron: pacientes entre los 4 y los 8 años de edad que presentaran lesiones cariosas cavitadas en dientes primarios, que se encuentraran activos para su atención por estudiantes de la Facultad de Odontología de la UCR, y que los padres o encargados legales firmaran el consentimiento informado para participar en esta investigación. Las muestras se tomaron utilizando una cuchareta estéril, colocándolas en viales de almacenamiento y fueron sometidas a diversas técnicas de identificación microbiana convencionales y moleculares tales como: identificación por Tinción de Gram, pruebas catalasa, oxidasa, TSI, API 20E, API STAPH y VITEK. De las 60 cepas bacterianas sometidas a tinción de Gram se obtuvo: 28 bacterias Gram Positivas y 32 bacterias Gram Negativas. Los principales organismos aislados fueron: especies de Staphylococcus epidermidis, Pasteurella pneumotropica/ Mannheimia haemolytica, Pantoea spp y Streptococcus mutans.

Vitalidade pulpar em lesões de cárie profundas após restaurações pelo Tratamento Restaurador Atraumático (ART) em molares decíduos: resultado após 24 meses de um ensaio clínico randomizado / Pulp vitality in deep carious lesions after Atraumatic Restorative Treatment (ART) restorations in primary molars: 24 months results of a randomized clinical trial

O objetivo desta tese foi avaliar a vitalidade pulpar de dentes decíduos com lesão de cárie profunda tratados com duas técnicas restauradoras. A taxa de sobrevivência da restauração foi avaliada como um desfecho secundário. Este volume apresenta um compilado do protocolo de pesquisa e os resultados de ensaio clínico randomizado (Clinicaltrials.gov registration NCT02903979) de não inferioridade com dois braços paralelos relatados pelas recomendações SPIRIT e CONSORT, respectivamente. Crianças de 4 a 8 anos com pelo menos uma lesão cariosa profunda oclusal ou ocluso-proximal em molares decíduos foram selecionadas na clínica odontológica da Universidade Ibirapuera. Cento e oito molares decíduos foram alocados em dois grupos: (1) restauração com cimento de hidróxido de cálcio seguido do cimento de ionômero de vidro de alta viscosidade (CHC + HVGIC) ou (2) restauração com HVGIC. A vitalidade pulpar e a sobrevivência da restauração foram avaliadas em 6, 12 e 24 meses. A análise por intenção de tratar foi usada para a vitalidade pulpar e a análise de sobrevida foi realizada com o método de Kaplan-Meier ( = 5%). Aos 24 meses, 86 restaurações foram avaliadas e 91 foram avaliadas pelo menos uma vez durante o estudo. A perda foi de 20%, e o número de participantes no início e no final do estudo foi semelhante entre os grupos (p = 0,872). Não houve diferença significativa entre os tratamentos restauradores em relação à vitalidade pulpar (CHC + HVGIC = 70% e HVGIC = 68,5%) (OR = 1,09; IC95% = 0,48-2,48). No entanto, as restaurações HVGIC (73%) apresentaram uma taxa de sobrevivência maior do que CHC + HVGIC (50%) (p = 0,021). Na análise de regressão de Cox apenas a variável tratamento apresentou p <0,20. Nesse sentido, a análise ajustada não foi realizada. Os dentes tratados com HVGIC tiveram 65% menos chance de falha do que aqueles tratados com CHC + HVGIC. Assim, pode-se sugerir que a aplicação de CHC é dispensável em lesões profundas de molares decíduos, visto que a longevidade da restauração é menor e a vitalidade pulpar não se altera com sua utilização.

Determinación del pH salival después de la aplicación de aceite ozonizado / Determination of salivary pH after application of ozonated oil

La saliva, compuesta principalmente por 99% de agua y 1% de moléculas orgánicas e inorgánicas, mantiene un rango de pH de 6.0 a 7.5, pero puede verse alterada por ciertos factores. En este estudio se determinó la variación del pH salival, luego de la aplicación tópica manual en mucosa masticatoria y órganos dentarios con aceite de girasol ozonizado de 300 mEq/kgO2, en jóvenes estudiantes de entre 21 a 23 años, como agente de neutralización en los cambios de pH. Se realizó un estudio comparativo longitudinal en 13 sujetos después de su cepillado dental; se tomaron dos muestras en saliva estimulada con el test estandarizado Saliva-Check BUFFER (GC®EUROPE). La medición basal de pH fue 7.66 ± 0.09, cifra por encima del rango normal; después de la aplicación del aceite de girasol ozonizado (O3MX®300IP) el pH fue de 7.27 ± 0.19, estableciéndose una variación de 0.28 ± 0.48, t = 8.04, p < 0.05 (0.000). Este estudio revela una caída significativa en el pH salival después de aplicar aceite de girasol ozonizado, lo que sugiere su potencial como buffer del pH salival. Se necesitan más investigaciones para explorar las implicaciones clínicas para el manejo de la salud oral (AU)

Saliva, primarily composed of 99% water and 1% organic and inorganic molecules, typically maintains a pH range of 6.0 to 7.5 but can be influenced by various factors. This study aimed to assess the variation in salivary pH following manual topical application of 300 mEq/kgO2 ozonated sunflower oil to the masticatory mucosa and dental structures in young individuals aged 21 to 23 years, using it as a pH-neutralizing agent. A longitudinal comparative study was conducted on 13 subjects after dental brushing. Stimulated saliva samples were collected using the standardized Saliva-Check BUFFER Test (GC®EUROPE). An initial baseline pH measurement of 7.66 ± 0.09 was obtained, which was above the normal range. Following the application of ozonated sunflower oil (O3MX®300IP), the pH dropped to 7.27 ± 0.19, indicating a variation of 0.28 ± 0.48 (t = 8.04, p < 0.05 (0.000). In conclusion, this study reveals a significant decrease in salivary pH after applying ozonated sunflower oil, suggesting its potential as a salivary pH buffer. Further research is needed to explore the clinical implications for oral health management.(AU)

Fluoruro de estaño en el control de cavidades sin restauración en dientes temporales / Stannous fluoride in nonrestorative cavity control in primary teeth

Introducción: el control de cavidades sin restauración (NRCC, por sus siglas en inglés), es una opción de tratamiento conservador y no invasivo para dentina cariosa, sobre todo en dentición temporal. Una de las estrategias del NRCC es la remineralización. El fluoruro de estaño (FDE) puede considerarse, como una opción viable ya que existe evidencia de su eficacia cariostática. Objetivo: valorar al FDE como remineralizante alternativo en dentina de molares temporales, asociado al NRCC. Material y métodos: se efectuó un estudio clínico, epidemiológico, y descriptivo con preescolares voluntarios de 3 a 5 años de edad con consentimiento firmado de participación en el estudio, y que presentaron molares con ICDAS 5 y 6. La aplicación del FDE a 0.8%, la evaluación de la dureza de la dentina con los criterios de Nyvad, y el diagnóstico del estado pulpar, la efectuó un operador entrenado para esta finalidad. Se aplicó un análisis estadístico descriptivo y uno no paramétrico. Resultados: el efecto cariostático producido por el FDE a 0.8%, sobre dentina afectada de molares temporales de niños mexicanos fue estadísticamente significativo durante cinco meses. Conclusiones: la aplicación de fluoruro de estaño puede considerarse como una alternativa de tratamiento cariostático asociado al NRCC para niños de 3 a 5 años de edad (AU)

Introduction: nonrestorative cavity control (NRCC), is a conservative and non-invasive treatment option for carious dentin, especially in primary dentition. One of the NRCC strategies is remineralization. Stannous Fluoride (SDF) can be considered as a viable option since there is evidence of its cariostatic efficacy. Objective: to evaluate FDE as an alternative remineralizing agent in the dentin of primary molars, associated with NRCC. Material and methods: a clinical, epidemiological, and descriptive study was carried out with preschool volunteers aged 3 to 5 years with signed consent to participate in the study, and who presented molars with ICDAS 5 and 6. The application of FDE at 0.8%, the evaluation of dentin hardness with the Nyvad criteria, and the diagnosis of pulp status, was carried out by an operator trained for this purpose. A descriptive and non-parametric statistical analysis was applied. Results: the cariostatic effect produced by 0.8% FDE on affected dentin of primary molars of Mexican children was statistically significant for five months. Conclusions: the application of stannous fluoride can be considered as an alternative cariostatic treatment associated with NRCC for children 3 to 5 years of age (AU)

O Diamino Fluoreto de Prata é uma opção para o tratamento de lesões de cárie não francamente cavitadas em superfícies oclusais em crianças?: achados sobre sua eficácia e aceitação dos pais em um ensaio clínico randomizado / Is Silver Diamine Fluoride an option for treating non-frankly cavitated caries lesions on occlusal surfaces in toddlers?: findings on its efficacy and parents acceptance from a randomized controlled trial

O uso do diamino fluoreto de prata (DFP) em lesões não fracamente cavitadas raramente é investigado. Esta dissertação apresenta resultados de um ensaio clínico controlado randomizado (ECR) delineado para avaliar se o DFP seria uma opção eficaz ao verniz fluoretado no tratamento dessas lesões na superfície oclusal de molares decíduos (NCT02789202). Além disso, trouxemos os resultados de uma revisão sistemática com meta-análise (CRD42020186245) sobre a percepção de responsáveis em relação ao uso do DFP e os resultado do ensaio sobre a aceitação deles ao tratamento de lesões de cárie não francamente cavitadas com DFP em crianças. No Capítulo 1, 109 crianças de 1 a 4 anos com pelo menos uma lesão de cárie ativa (ICDAS 1 a 3) em molares decíduos foram randomizadas em DFP e verniz fluoretado e acompanhadas por 24 meses. Análises por intenção de tratar adotando regressão logística multinível e regressão de Cox com fragilidade compartilhada foram realizadas. 309 molares foram incluídos e 239 reavaliados. DFP preveniu mais progressão (91%) do que o verniz (81%). As lesões tratadas com DFP apresentaram, em media, 69% menos chance de progressão quando o modelo foi ajustado pela severidade (lesões iniciais vs microcavitadas). A progressão demorou mais para ocorrer no grupo do DFP. Para o Capítulo 2, foi realizada uma busca nas bases de dados MEDLINE, Scopus, Web of Science, Embase e Open Grey até maio de 2020. Foram incluídos ECR, estudos clínicos não randomizados e estudos observacionais que avaliaram a percepção de responsáveis sobre compostos de prata no tratamento de lesões de cárie. O risco de viés foi avaliado utilizando uma ferramenta específica para estudos de atitutes e práticas. Para a meta-análise, os estudos foram separados considerando se os entrevistados receberam o DFP como tratamento de seus filhos ou não e se foram obtidos quanto a satisfação geral ou quanto, especificamente, a descoloração. Análises de subgrupo e meta-regressão foram realizadas para avaliar a influência de variáveis associadas ao instrumento na percepção e explorar possíveis fontes de heterogeneidade. 19 estudos foram incluídos na revisão sistemática e 12 na metaanálise. A aceitação geral do tratamento foi de moderada a bem aceita (26.9% a 100%) e variou de acordo com a metodologia utilizada. Em geral, responsáveis responderam mais positivamente quando a criança recebeu o tratamento (90%) do que quando a aplicação foi mostrada com uma foto (59%). Por fim, avaliou-se a percepção dos responsáveis sobre a saúde e estética em crianças que tiveram lesões em esmalte tratadas com DFP (Capítulo 3). Crianças incluídas em três ECR que tiveram as lesões em esmalte tratadas com DFP ou não foram consideradas. Um questionário padrão foi utilizado. Primeiramente, avaliamos a percepção geral e, em seguida, focada nos dentes tratados. Análise multiníveis foram realizadas para comparar a percepção de responsáveis de crianças tratadas vs não tratadas com DFP. Os níveis foram definidos conforme o dente e a criança/responsável. O tratamento com DFP não afetou a percepção geral dos responsáveis sobre as condições estética e de saúde bucal relacionadas a criança (85%). No entanto, quando a avaliação foi focada no dente tratado, a percepção naquelas crianças que receberam tratamento com DFP foi pior do que naquelas que não receberam. Concluindo, o DFP é uma opção eficaz no controle de lesões de cárie não francamente cavitadas. Além disso, geralmente, parece ser aceito de maneira adequada pelos cuidadores. No entanto, um padrão diferente de aceitação é observada quando destacamos o dente tratado, mostrando que a educação/informação é uma questão importante na indicação desse tratamento em crianças.

Risk factors associated with occlusal caries in first permanent molars in a school program: longitudinal study

Aim: Evaluate the longitudinal status of dental caries in the occlusal surface of first permanent molars (FPM) and to identify risk factors for the progression to cavitated caries lesions in a school oral health program. Methods: Children who were enrolled in the program between September 2017 and October 2019, 5 to 10 years-old, presenting the four FPM were included. Four calibrated examiners assessed dental caries according to Nyvad criteria. Descriptive analysis included frequency, mean, and standard deviation calculations. Chi-square test was used in the bivariate analysis and, logistic regression adjusted for cluster effect was used to identify significant risk factors for cavity among the following independent variables: gender, age in the baseline, deft, upper/lower molar, initial caries score, Molar Incisor Hypomineralization (MIH), fluorosis, occlusal sealing. Odds ratio (OR) and respective confidence intervals (CI) are presented. Results: From 174 children enrolled in the program between 2017/2019, 120 were reevaluated in 2022. Eleven (2.6%) FPM in 11 children (9.2%) presented cavitated caries in the follow up examination. Significant risk factors for cavity were caries experience in the primary teeth (OR = 5.59; CI: 1.4 ­ 22.3) and the presence of MIH (OR = 5.33; CI: 1.6 ­ 18.1). Most of the active lesions in the follow up were considered active in the baseline examination. Conclusions: The progression to cavity was relatively low, significantly influenced by past caries experience and MIH

Can oral health have an impact on academic performance and school absenteeism?: a systematic review and meta-analysis

Aim: The study aimed to evaluate the association between oral health and academic performance and/or school absenteeism. Methods: Electronic searches were performed of the PubMed, Web of Science, SCOPUS and LILACS/BVS databases. We included observational studies that evaluated the association between dental caries, tooth loss, dental pain or oral health status with school absenteeism or academic performance. The studies had to contain a representative sample of the population: schoolchildren, children or adolescents. After the removal of duplicates, the electronic searches produced 3,789 articles. Of these, 25 studies were included in the systematic review and 13 in the meta-analysis. Results: Considering all the studies evaluated in the meta-analysis, seven articles satisfied 100% of the Joanna Briggs Institute Critical Appraisal checklist, and six contained between 90% and 75% positive answers. The pooled effects showed that the chances of school absenteeism were 31% higher in subjects with dental caries (OR 1.31; 95%CI 1.12-1.54). Students with fair/poor dental health had a 50% higher chance of suffering poor academic performance (OR 1.50; 95%CI 1.22-1.84) and 34% higher chance of having problems at school (OR 1.34; 95%CI 1.06-1.70). Students with a history of toothache had a 3.7 higher chance of being absent from school (OR 6.65; 95%CI 1.60-8.32) and 71% higher chance of missing class due to toothache (OR 1.71; 95%CI 1.15-2.56). Subjects with a history of toothache had a 2.5 times higher chance of suffering poor academic performance (OR 2.58; 95% CI 2.04-3.27). Conclusion: Therefore, students with oral problems were more likely to take time off school and present inferior academic performance

Influence of notebook computers screens and undergraduate level of dental students in the radiographic detection of carious lesions

Aim: To evaluate the influence of notebook computers screens and undergraduate level of dental students in the radiographic detection of carious lesions. Methods: Bitewing digital radiographs were presented to 3rd and 5th year dental students in three different notebooks computers: Notebook 1 with anti-glare screen (1366×768 pixels), Notebook 2 without anti-glare screen (1366×768 pixels), and Notebook 3 with anti-glare screen (1920×1080 pixels). A reference standard based on a consensus analysis was set by three senior professors of Oral Radiology and Cariology. Sensitivity, specificity and accuracy values were measured and submitted to two-way ANOVA at a significance level of 5%. Results: Notebook 2 provided significantly lower sensitivity values (Mean 56.5% ± 2.94) than notebook 3 (71.1% ± 2.82) (p = 0.002). We found no statistically significant differences between the two undergraduate years (p > 0.05). Conclusion: The anti-glare screen of notebook computers screens can influence the radiographic detection of carious lesions, but the undergraduate level of dental students does not influence this diagnostic task

Incidence of Dental Caries and Associated Factors in the School Period in a Municipality in Southern Brazil

Abstract Objective: To estimate the incidence of dental caries and associated factors in the school period from six/seven to ten years of age. Material and Methods: A longitudinal study involving 168 children was followed up between 2015 and 2019 in the municipality of Palhoça, Brazil. The dependent variable was the caries incidence rate in the mixed dentition. The independent variables included information regarding demographic and socioeconomic status. Multivariate analyzes were carried out using Poisson Regression with a robust estimator. Variables with p <0.20 in the bivariate analysis were included in the adjusted model. Relative risks were estimated, as well as 95% confidence intervals. Results: Of 168 followed schoolchildren, 32 developed the disease, providing an incidence rate of 19.0%. Female children had a 10% higher risk [RR = 1.10 (95% CI 1.03; 1.18)] of developing caries than males. Also, children born from fathers with ≤ 8 years of schooling at baseline had a 9% higher risk [RR = 1.09 (95% CI 1.01; 1.16)] of developing dental caries compared to fathers with higher education. Conclusion: The incidence of dental caries in a four-year period was 19.0%. Females and children born from fathers with a lower level of education showed higher incidence rates.

Impact of Molar Incisor Hypomineralization on Oral Health-Related Quality of Life in Brazilian Schoolchildren Aged 8 to 10 Years

ABSTRACT Objective: To assess the impact of Molar Incisor Hypomineralization (MIH) and confounding factors on oral health-related quality of life (OHRQoL) according to the perception of 8 to 10-year-old children and their parents/caregivers. Material and Methods: A cross-sectional study including 403 students aged 8-10 years was carried out, in which OHRQoL was measured using the Child Perceptions Questionnaire administered to both children and parents/caregivers. The diagnosis of MIH was performed according to the previously proposed index. Dental caries experience, malocclusion, and sociodemographic factors were evaluated as confounders. Cluster analysis and Poisson regression with robust variance (p<0.05) were performed. Results: The prevalence of MIH was 13.4%. Parents/caregivers of children with MIH in incisors showed a higher impact prevalence in the emotional well-being domain (PR=1.92; 95%CI=1.16-3.19). Children with hypoplasia had a higher prevalence of negative impact on OHRQoL in the oral symptoms domain (PR=1.51; 95%CI=1.03-2.23). According to the perception of parents/caregivers, dental caries experience had a negative impact on the quality of life of students in the emotional well-being domain (PR=4.19; 95%CI=1.06-16.49) and in the total questionnaire score (PR=3.21; 95%CI=1.06-9.71). Conclusion: According to the perception of parents/caregivers, children with MIH in incisors showed a greater impact on OHRQoL. Additionally, the presence of hypoplasia affected the self-perception of OHRQoL in children, and caries experience influenced the OHRQoL of children, as perceived by parents/caregivers.

Clinical Findings Arising from the Use of Silver Diamine Fluoride to Prevent or Treat Caries Lesions and Dentinal Hypersensitivity: A Data Mining Analysis

Abstract Objective: To summarize data of clinical trials that used silver diamine fluoride (SDF) to prevent and treat caries lesions and dentinal hypersensitivity. Material and Methods: Six electronic databases were searched in May 2022. The concentration of SDF, type of usage (alone/combined), dentition, anterior/posterior teeth, tooth region, dental tissue, number of the treated surfaces, the intervention environment, participants' age, frequency and duration of SDF application, purpose, and outcome were the extracted variables. The type of study, year of publication, authors, journals, and country were also investigated. Results: From 8860 articles, S3 were selected. Most were randomized (n=38), that applied 38% SDF (n=43), alone (n=44), on multiple surfaces (n=44), only in dentin (n=36), of the crown (n=46) of anterior and posterior (n=36) primary teeth (n=39). The studies were preferably carried out outside the clinic (n=3l), only in children (n=33), with reapplication of SDF (n=30), but did not inform the duration of application (n= 19). SDF was most used to treat (n=46) only caries lesions (n=50). They were published between 2001 and 2022, mainly in the Journal of Dentistry (n=10). China (n=19) and Lo E.GM (n=19) were the countries and authors that published the most, respectively. Conclusion: The silver diamine fluoride 38% alone was most used to treat caries lesions in the dentin of the crown of all primary teeth, preferably applied on multiple surfaces, requiring re application, and outside the clinic.

Profile of Dental Caries in Eastern and Western Parakanã Children at Amazônia Paraense, Brazil

ABSTRACT Objective: To evaluate the prevalence of dental caries in children from 18 months to 5 years of age in eastern (near urban centers) and western (far from urban centers) Parakanã, verify the influence of proximity to non-indigenous cultures, and compare with other ethnicities and non-indigenous. Material and Methods: The universe of children was examined by one researcher in a cross-sectional study. Descriptive analysis and the Mann-Whitney test (p<0.05) were performed. Results: It was observed that 68.8% (N = 53) of children from 18 to 36 months of age presented dmft = 0 (without caries), while 12.5% (N = 6) of children of five years of age presented this condition. For children between 18 and 36 months, the average dmft values were 0.74 (SD=1.91) for eastern children and 1.25 (SD=1.65) for western children. At five years of age, the average dmft values were 4.35 (SD=3.29) and 3.75 (SD=2.05) for eastern and western, respectively. Mann-Whitney test (p<0.05) showed no difference between East and Western children. When compared with non-indigenous Brazilian children, the values behaved similarly. Conclusion: Knowledge of the epidemiological profile of dental caries in Indigenous Parakanã children is relevant both in planning oral health actions for this population and for aggregating information, which is still scarce for Indigenous.

Early Childhood Caries in a Northeastern Brazilian Capital: Observations of Social Distinct Daycare Centers

ABSTRACT Objective: To investigate factors associated with the experience of dental caries in children in early childhood in two socially distinct centers in the city of São Luís, Maranhão, Brazil. Material and Methods: A cross-sectional study was conducted in two socially distinct daycare centers (private and public). The children were assessed regarding their caries experience, and their parents/guardians were prepared regarding socioeconomic information, parents/guardians' habits, and children's habits. Descriptive and inferential statistics were used. Association tests and multivariate analyses were performed to analyze independent variables and outcomes (type of daycare center and caries experience) using a p-value of 5%. Results: The sample consisted of 89 children aged up to 5 years of both sexes. The type of daycare center was associated with some socioeconomic data, such as family income (p<0.01) and parents' education (p=0.05). Data on oral hygiene and children's habits, such as breastfeeding, also remained associated with the type of daycare center. There was an association between income and DMFT (PR=8.48 - 95%CI 2.26;31.78). Conclusion: The socioeconomic profile of parents/guardians and breastfeeding were associated with the prevalence of caries in deciduous teeth in children aged 10 to 48 months.

Relationship Between Celiac Disease and Dental Caries in Children and Adolescents: A Systematic Review and Meta-Analysis

ABSTRACT Objective: To assess the relationship between celiac disease and the prevalence of dental caries in children and adolescents and also evaluate if dental enamel defects in celiac children predispose to dental caries. Material and Methods: Searches were performed in the following databases: PubMed, Scopus, Cochrane Library, Latin American and Caribbean Literature on Health Sciences, and OpenGrey. The risk of bias was assessed using the Newcastle-Ottawa Scale. DMFT/dmft and DMFS/dmfs data of observational studies that compared the prevalence of caries between children and adolescents with celiac disease and healthy individuals. Meta-analysis was performed using a random effects model. Heterogeneity between studies was estimated using Cochran's Q test, and inconsistency was measured using I2 statistics. Results: Of the 121 studies retrieved, 17 were selected, and 12 were included in the meta-analysis. The prevalence of caries in the primary dentition (dmft) did not differ between celiac patients and controls [SMD = -0.35; 95% CI (-0.83; 0.13); p = 0,15; I2 = 89%]. There was also no difference in the prevalence of caries in permanent teeth (DMFT) between groups [SMD = -0.44; 95% CI (-1.02; 0.14); p = 0.14; I2 = 95%]. Conclusion: Celiac disease is not a determinant factor in the development of dental caries in children and adolescents compared to the control group.

Relación entre el índice CPOD y la limitación para socializar en escolares de Ecuador / Relationship between the DMFT index and the limitation to socialize in schoolchildren from Ecuador

Introducción: La Organización Mundial de la Salud define a la caries dental como un problema de salud mundial que afecta entre el 60 al 90% de la población. Se considera una enfermedad transmisible de origen multifactorial, que evoluciona de manera progresiva hasta ocasionar la destrucción de los tejidos duros. Objetivo: Determinar la relación entre dientes cariados, perdidos y obturados, y la limitación para socializar en escolares de Ecuador. Métodos: Se realizó un estudio descriptivo de tipo correlacional sobre una población de 154 escolares de 12 años de la parroquia el Batán, de Cuenca-Ecuador (2016); para el análisis estadístico los datos fueron ingresados al programa SPSS, donde se efectuó estadística descriptiva para cada una de las variables y la limitación para socializar. Resultados: Se logró constatar que la población objeto presentó un índice de CPOD muy bajo (32,5 %), de igual forma se evidenció que el 62,7% no presentó limitación a la hora de socializar. En cuanto a la correlación entre ambas variables, se mostró una asociación positiva con un nivel de significancia de p=0,002. Una de las principales limitaciones del estudio fue el escaso contacto con los participantes. Se recomienda, efectuar investigaciones epidemiológicas longitudinales con la finalidad de observar la variación del coeficiente de correlación de las variables en fases de pretratamiento y de postratamiento. Conclusión: Al finalizar el estudio, se demostró que existe correlación estadística entre el índice CPOD y la limitación en el desempeño socializar en los escolares de 12 años de la parroquia el Batán.

Introduction: the World Health Organization defines dental caries as a global health problem that affects between 60 and 90% of the population. It is considered a communicable disease of multifactorial origin, which evolves progressively until it causes the destruction of hard tissues. Objective: to determine the relationship between decayed, missing and filled teeth and the limitation to socialize in schoolchildren from Ecuador. Methods: a descriptive correlational study was carried out on a population of 154 schoolchildren aged 12 years from the El Batán parish, Cuenca-Ecuador (2016); data was entered into the SPSS program for the statistical analysis, where descriptive statistics were performed for each of the variables and for the limitation to socialize. Results: it was possible to verify that the target population had a very low DMFT index (32.5%); in the same way it was evidenced that 62.7% did not have limitations when socializing. A positive association, with a significance level of p=0.002, was shown regarding the correlation between both variables. One of the main limitations of the study was the limited contact with the participants. We recommend to carry out longitudinal epidemiological investigations in order to observe the variation of the correlation coefficient of the variables in the pre-treatment and post-treatment phases. Conclusion: we showed, at the end of the study, that there is a statistical correlation between the DMFT index and the limitation in socializing performance in 12-year-old schoolchildren from the El Batán parish.

Impact of oral onditions on Quality of Life in Peruvian Preschoolers in Rural and Urban Areas / Impacto de las alteraciones bucales en la calidad de vida de preescolares peruanos de zonas rurales y urbanas

Abstract The objective of this study is to determine the impact of oral conditions on the quality of life related to the oral health of preschool children in a rural and urban area of Cusco. The study was descriptive and cross-sectional, from a population of 179 preschoolers aged 3 to 5 years, from two public early childhood education institutions, and their respective parents or caregivers in the department of Cusco, Peru. We worked with the entire population that met the inclusion and exclusion criteria, seventy-four preschool children were selected for each area, deciding to have the same amount of children per group based on the smallest group. A clinical odonto-stomatological examination was carried out for oral conditions (dental caries, malocclusion, and dental trauma) according to the WHO's criteria and a survey that was used for sociodemographic characteristics. In addition, a validated Peruvian version of the ECOHIS questionnaire was used to obtain data on the impact on quality of life. All the variables of the total and individual scores of the ECOHIS domains were analyzed individually and the Kruskal-Wallis test was used to determine the association between variables. The oral conditions prevalence in preschool children in rural areas referring to dental caries was 100% (dmft index > 6), dental trauma 10.8%, and malocclusions 60.8%; for the urban area dental caries was 93.2% (dmft index > 6), dental trauma 9.5% and malocclusions 36.5%. Of the three oral conditions only the experience of dental caries was related to the OHRQOL of preschoolers in urban and rural areas.

Resumen El objetivo de este estudio es determinar el impacto de las alteraciones bucales en la calidad de vida relacionada con la salud bucal de niños preescolares de una zona rural y urbana de Cusco. El estudio fue descriptivo y transversal, de una población de 179 preescolares de 3 a 5 años de edad, de dos instituciones públicas de educación inicial, y sus respectivos padres o cuidadores en el departamento de Cusco, Perú. Se trabajó con toda la población que cumplió con los criterios de inclusión y exclusión, se seleccionaron setenta y cuatro niños preescolares por cada área, decidiendo tener la misma cantidad de niños por grupo en base al grupo más pequeño. Se realizó un examen clínico odonto-estomatológico para detectar alteraciones bucales (caries dental, maloclusión y trauma dental) según los criterios de la OMS y una encuesta que se utilizó para las características sociodemográficas. Además, se utilizó una versión peruana validada del cuestionario ECOHIS para obtener datos sobre el impacto en la calidad de vida. Todas las variables de los puntajes totales e individuales de los dominios ECOHIS fueron analizadas individualmente y se utilizó la prueba de Kruskal-Wallis para determinar la asociación entre variables. La prevalencia de alteraciones bucales en niños preescolares de zonas rurales referida a caries dental fue del 100% (índice dmft > 6), traumatismo dental 10,8% y maloclusiones 60,8%; para la zona urbana la caries dental fue del 93,2% (índice dmft > 6), el traumatismo dental 9,5% y las maloclusiones 36,5%. De las tres alteraciones bucales, sólo la experiencia de caries dental se relacionó con la OHRQOL de los preescolares de las zonas urbana y rural.

Serotipos prevalentes de Streptococcus mutans en América Latina / Prevalent serotypes of Streptococcus mutans in Latin America

La microbiota oral está conformada por diversas especies bacterianas que en condiciones normales desempeñan una función protectora del huésped; sin embargo, cuando existe un desequilibrio en el ecosistema, estos microorganismos son capaces de producir diversas manifestaciones como lo es el caso de la caries dental, enfermedad infecciosa producida principalmente por Streptococcus mutans, patógeno capaz de desmineralizar los tejidos duros del diente mediante la fermentación de hidratos de carbono obtenidos de la dieta. Se ha identificado en la pared celular de este microorganismo ocho serotipos que intervienen en la adhesión, agregación y coagregación bacteriana. En los seres humanos S. mutans presenta los serotipos c, e y f, siendo el serotipo c el más prevalente a nivel mundial, el cual se conoce que está asociado a pacientes sanos, a diferencia del e y f que son capaces de invadir las células endoteliales de las arterias coronarias. No obstante, en los últimos años se ha logrado identificar el serotipo k que de igual manera presenta alta capacidad de invadir el endotelio humano, actuando en la patogénesis de las enfermedades cardiovasculares. El objetivo de la presente revisión bibliográfica es lograr cuantificar los serotipos prevalentes de S. mutans en América Latina (AU)

The oral microbiota is made up of various bacterial species that under normal conditions perform a protective function of the host, however, when there is an imbalance in the ecosystem, these microorganisms are capable of producing various manifestations such as caries, an infectious disease. produced mainly by Streptococcus mutans, a pathogen capable of demineralizing the hard tissues of the tooth through the fermentation of carbohydrates obtained from the diet. Eight serotypes involved in bacterial adhesion, aggregation and coaggregation have been identified in the cell wall of this microorganism. In humans, S. mutans presents serotypes c, e, and f, serotype c being the most prevalent worldwide, which is known to be associated with healthy patients, unlike e and f, which are capable of invading the endothelial cells of the coronary arteries. However, in recent years it has been possible to identify serotype k, which also has a high capacity to invade the human endothelium, acting in the pathogenesis of cardiovascular diseases. The objective of this literature review is to quantify the prevalent serotypes of S. mutans in Latin America (AU)

Avaliação da profundidade da cárie proximal nos exames radiográfico convencional e digitalizado / Evaluation of the size of proximal caries in radiography and digitized

Introdução: A cárie dentária é uma doença multifatorial que compreende vários fatores biológicos e sociais. A superfície proximal dos dentes é uma região de difícil visualização que pode esconder pequenas lesões cariosas no esmalte dentário, impossibilitando o diagnóstico através de inspeções visuais e táteis. Objetivo: O objetivo deste trabalho foi avaliar a profundidade da cárie proximal nos exames radiográficos convencionais e digitais, comparando as profundidades das lesões consideradas nestes exames às do exame histológico. Método: Foram utilizados exames radiográficos interproximais de 40 dentes humanos, 20 pré-molares e 20 molares, com alterações clínicas em uma das superfícies proximais, como lesões de mancha branca ou acastanhada e pequenas cavitações. Três profissionais especializados em radiologia odontológica com mais de cinco anos de experiência clínica mediram a profundidade das lesões pelos exames radiográfico e digital das amostras. Para obter os resultados, utilizou-se a técnica de análise de variância (ANOVA). Resultados: Constatou-se um nível de significância de 5% nas mensurações dos exames radiográficos convencionais e digitalizados, mostrando a fidelidade das imagens radiográficas em relação a real profundidade da lesão. Conclusão: Conclui-se que os exames de imagem avaliados foram eficientes na determinação da profundidade das lesões de cárie proximal.

Introduction: Dental caries is a multifactorial disease that comprises several biological and social factors. The proximal surface of the teeth is a region of difficult visualization that can hide small carious lesions in the dental enamel, making diagnosis through visual and tactile inspection infeasible. Objective: The objective of this study was to evaluate the depth of proximal caries in the conventional and digitized radiographic examinations, comparing the depths of the lesions considered in these examinations to those of the histological examination. Method: Interproximal radiographic examinations of 40 human teeth, 20 premolars and 20 molars, with clinical alterations on one of the proximal surfaces, such as white or brown spot lesions and small cavitations, were used. Three professionals specialized in dental radiology with more than five years of clinical experience measured the depth of the lesions by radiographic examination of the samples. To obtain the results, we used the technique of analysis of variance (ANOVA). Results: A level of significance of 5% was found in conventional and digitized radiographic measurements, showing the fidelity of the radiographic images in relation to the actual depth of the lesion. Conclusion: It was concluded that the imaging tests evaluated were efficient in determining the depth of proximal caries lesions.

Exodontia de primeiro molar superior permanente em criança: relato de caso / Clínico maxillary first permanent molar extraction in a child: case report

Entre as perdas precoces de um elemento dental ocorre em grande frequência a do primeiro molar permanente, que normalmente tem o seu irrompimento por volta dos 6 anos de idade, e são propensos a serem acometidos por lesões cariosas que se não cuidadas precocemente pode-se levar a perda do elemento dental. Há também outros agentes que ocasionam a perda do elemento como o trauma de baixa intensidade, tais como, os cálculos dentários, os hábitos bucais deletérios e principalmente a falta de motivação de higiene oral. Diante disto, este trabalho visa a apresentação de um caso clínico de um paciente de 9 anos de idade, sem alterações sistêmicas, com grande destruição coronária no dente 26. Os exames de imagens foram colaboradores para diagnóstico e definição da extração. Foi realizada a exodontia em campo aberto. O paciente foi instruído quanto à higiene bucal e futuramente encaminhado para um tratamento ortodôntico. Conclui-se que o Cirurgião Dentista tem papel fundamental no diagnóstico e tratamento dessas alterações dentais, enfatizando a importância do tratamento restaurador de lesões cariosas precocemente, remoção de qualquer agente irritante de baixa intensidade e na motivação da higiene bucal(AU)

Among the early loss of a dental element, the loss of the first permanent molar occurs very frequently, which usually has its eruption around the age of 6 years, and they are prone to be affected by carious lesions that, if not treated early, can if it leads to loss of the dental element. There are also other agents that cause the loss of the element, such as low-intensity trauma, such as dental calculi, deleterious oral habits and especially the lack of motivation for oral hygiene. Therefore, this work aims to present a clinical case of a 9-year-old patient, without systemic alterations, with great coronary destruction in tooth 26. The imaging exams collaborated for the diagnosis and definition of the extraction. The extraction was performed in an open field. The patient was instructed about oral hygiene and later referred for orthodontic treatment. It is concluded that the Dental Surgeon has a fundamental role in the diagnosis and treatment of these dental alterations, emphasizing the importance of an early restorative treatment of carious lesions, removal of any low-intensity irritant and in the motivation of oral hygiene(AU)
