Evaluation of the effect of repeated local fluoride application on the prevention of new caries in 3-year-old children with active caries / 上海预防医学

ObjectiveTo evaluate the caries prevention effect of different fluoride application frequencies in 3-year-old children with active caries. MethodsA total of 337 3-year-old children with dental caries from 12 kindergartens in Changning District of Shanghai were divided into three groups： group 1 received fluoride application once every three months， group 2 received fluoride application once every six months， and the control group received no fluoride application. At baseline， parents completed a questionnaire survey， and oral examinations were conducted at baseline， 7 months， and 16 months after the fluoride intervention to assess the incidence of new dental caries， new dmft， and new dmfs of children. Multivariate logistic regression analysis was used to analyze the relationship between fluoride application and new dental caries， with new dental caries as the dependent variable and local fluoride application， child's gender， age in months， parents' highest education level， frequency of sugary intake （desserts， candies， sweet beverages）， age of toothbrushing initiation， frequency of daily toothbrushing， use of fluoride toothpaste， parental assistance in child’s toothbrushing， and daily use of dental floss as the independent variables. ResultsThere were no significant differences in baseline general conditions and oral health behaviors among group 1 （121 cases）， group 2 （123 cases） and the control group （93 cases） （all P>0.05）. After 16 months' intervention， three children were lost to follow-up due to transferring schools. The new caries rates of group 1 （120 cases）， group 2 （121 cases） and the control group （93 cases） were 5.83%， 24.79% and 52.69%， respectively. The incidence of new caries was significantly lower in group 1 compared to group 2 and the control group （P<0.001）， and it was also significantly lower in group 2 compared to the control group （P<0.001）. The newly-increased caries of group 1， group 2 and the non-fluoride control group were all 0.12 0.52， 0.36 0.68 and 1.16 1.39， respectively. The mean increment of new caries was lower in group 1 compared to group 2 （P=0.040） and the non-fluoride control group （P<0.001）， and it was lower in group 2 compared to the non-fluoride control group （P<0.001）. After adjusting for factors such as gender， parents' education level and child's oral health behaviors by multivariate logistic regression， the results showed that fluoride application once every three months could significantly reduce the risk of dental caries （OR=0.04， P<0.001）. ConclusionLocal use of fluoride has a certain effect on the prevention and treatment of dental caries in children with active caries. Fluoride application once every three months effectively reduces the incidence of new caries and slows down the progression of caries lesions. It is suggested that local application of fluoride should be implemented once every three months for children with active caries.

Oral Health Status and Salivary Parameters in Stroke Patients at a Tertiary Hospital

@#Introduction: Dental caries and impaired salivary function are very common but undertreated. The aim of this study was to investigate the oral health status and salivary parameters of stroke patients. Methods: A cross-sectional study was carried out on 54 stroke and 54 non-stroke patients attending rehabilitation treatment at Hospital Universiti Sains Malaysia. Decay, Missing and Filled Teeth (DMFT) index and plaque scores were used to evaluate patients’ oral health. Salivary parameters such as salivary cortisol, salivary flow rate, pH and buffering capacity were measured. Salivary cortisol was analysed using Cobas E6000 automated immunoassay. Results: Among the 54 stroke patients, the majority were Malays 72.2% and 63.0% were male, with a mean age of 48.1 (14) years. There was a significant difference of dental caries between stroke patients, at 17.6 (4.26), compared to 15.7 (5.38) for non-stroke patients (p=0.042). Only 53.7% of stroke patients had good oral hygiene, compared to, 85.2% among non-stroke patients’ (p-value= 0.001). Salivary parameters showed no significant differences (p>0.05). However salivary cortisol levels were higher in stroke patients 5.2(5.1) nmol/L) than in non-stroke patients 4.0 (3.6) nmol/L). There was no significant correlation between salivary parameters and DMFT index (P>0.05). Conclusion: Stroke patients had more dental caries and poor oral hygiene compared to non-stroke patients. Salivary parameters showed no significant difference between stroke and non-stroke patients.

Prevalence of Early Childhood Caries in India: A Systematic Review and Meta-Analysis

This review was designed to assess the pooled prevalence of early childhood caries (ECC) in India. An electronic data search was done in PubMed/MEDLINE and Scopus databases in October 2020. Epidemiological surveys assessing the prevalence of ECC were included, and data on gender, geographic region, sampling strategy, feeding habits, and dmft values were extracted. The risk of bias was assessed, and a meta-analysis was performed for pooled prevalence and mean dmft values. The selection of articles, data extraction, and validity assessment were done independently by the two reviewers(ID and RV). Athird reviewer (CJ) resolved any conflict between these two reviewers. Atotal of seventy?one studies were included for quantitative analysis. The pooled prevalence of ECC estimated from 71 studies with 69,330 participants is 46.9% (confidence interval [CI] 46.5–47.2). Males had a higher prevalence of ECC (47%, CI: 46.4–47.6,40 studies, 26,840 participants) than females (43.8%, CI: 43.2–44.2,40 studies, 24,389 participants). Region?wise analysis showed the highest number of studies (44) in southern India, with a sample size of 35,988 with a pooled prevalence of 44.6% (CI: 44–45.1). The pooled mean dmft (random effect) is 2.23 (1.97–2.48), with males having a higher proportion of 2.26 compared to 2.23 in females. The pooled prevalence of ECC was 46.9%, and the pooled mean was 2.23. The results from this study state that one in every two children in India is suffering from ECC, reflecting its public health relevance.

Caries experience scores revisited for caries risk assessment using cariogram model – A cross-sectional study

Context: The widely accepted caries risk assessment tools such as the Cariogram model needs modifications in the scoring of different factors for reliable results. Aims: The study was aimed to report the caries experience in 3?60 years of the Rajasthan population and to apply the newly derived average decayed exfoliated filled teeth/Decayed Missing Filled Teeth (deft/DMFT) scores in the Cariogram model to assess the caries risk. Settings and Design: The cross?sectional study was planned in the Department of Dentistry and a total of 500 participants were equally divided into five groups (3?6, 7?12, 13?30, 31?44, and 45?60 years) were included. Methods and Material: All participants were examined for caries detection using deft/DMFT, ICDAS, and CAST indices according to the predefined protocol. A single examiner evaluated the participants in a dental operatory and data was recorded. Statistical Analysis Used: One?Way ANOVA and Tukey’s Post?Hoc tests were used to evaluate the significant difference between the groups of each caries index. Results: A statistically significant difference was observed between the mean deft/ DMFT and CAST scores of 3?6, 7?12, and 13?30 age groups with the 45?60 years age group. Caries prevalence was highest (83%) in 31?44 and 45?60 year age groups and lowest (51%) in the 3?6 year age group. Conclusions: Caries experience scores increase as the age increases and the highest scores were observed in 31?44 and 45?60 year age groups and the lowest were observed in the 3?6 year age group. The average ICDAS and CAST scores were higher when compared to the deft/DMFT index

Prevalence of dental fluorosis and dental caries in fluoride endemic areas of Rohtak district, Haryana

Objectives: This study investigates the estimation of the fluoride concentration in drinking water in Rohtak district, Haryana, and quantifies its effect on the prevalence of dental fluorosis and dental caries. Materials and Methods: A cross-sectional survey was conducted among 1262 school children in endemic fluoride areas of Haryana. Using simple random sampling, thirty villages from five blocks of Rohtak districts were selected, and children 6–12 years of age were examined. A questionnaire survey form was filled out to record the demographic details of the samples. Dental caries was recorded according to DMFT (D = Decayed, M = Missing due to caries only, F = Filled, T = Teeth)/deft index (d = decayed, e = extracted due to caries, f = filled, t = teeth). Assessment of Dental Fluorosis was done according to Dean's Fluorosis index, modified in 1942. The data were analyzed using SPSS version 19, and nonparametric tests were used to assess the significance. Results: The study participants included 615 males and 647 females among which Mean DMFT in the area of study ranged from 0.32 to 1.90. Mean deft in the area of study ranged from 0.34 to 1.91. The fluoride concentrations in groundwater are in the range of 0.532–8.802. Out of 1262 children examined, 655 (51.90%) children were having dental fluorosis. 607 (48.10%) of the subjects were free from fluorosis. 16.09%, 13.39%, 9.11%, and 8.16% and 5.15% were having questionable, very mild, mild, moderate, and severe form of fluorosis, respectively. Conclusion: It can be concluded that in Rohtak district, the fluoride levels in drinking water and the prevalence of dental fluorosis are high, so requiring an urgent need to improve the quality of water and institute de-fluoridation of drinking water in affected areas to lower the burden of dental fluorosis in the community.

RESUMEN De acuerdo a la literatura, los pacientes hospitalizados con trastornos mentales (TM), tienen mayor riesgo a desarrollar caries y enfermedad periodontal que la población general, asociado a la dificultad motora para hacerse una adecuada higiene oral, a los efectos adversos que ocasionan los medicamentos para el control de los síntomas psiquiátricos y a la falta de cuidado oral y atención clínica. El objetivo era realizar una revisión sistemática de la literatura sobre el estado de salud oral de pacientes hospitalizados con TM. Se hizo una búsqueda sistemática de la literatura en PubMed, de acuerdo con la metodología de la declaración PRISMA, a través de los descriptores en salud MeSh "Dental Caries" y "Mental Disorders" a febrero de 2017. De acuerdo a los diferentes filtros que fueron aplicados, se obtuvieron 14 artículos que describieron el estado de salud oral -mediante el índice COP-D (dientes con caries, dientes con restauraciones, dientes perdidos y dientes con extracción mandatoria)- de pacientes hospitalizados con TM. Se debe promover el reconocimiento de la importancia de la salud oral por parte de los profesionales de la salud, cuidadores y familiares; se debe explorar la cavidad oral para determinar el estado de salud además de instruir a los pacientes y personal de apoyo en higiene oral; las instituciones de salud mental deben establecer un programa de intervención para eliminar focos infecciosos orales y luego implementar un programa preventivo multidisciplinario para mantener la salud oral de acuerdo al diagnóstico del TM.

ABSTRACT According to the literature, hospitalized patients with mental disorders have a higher risk of developing cavities and periodontal disease than the general population, associated with the motor difficulty to perform adequate oral hygiene, to the adverse effects caused by drugs for the control of psychiatric symptoms, as well as the lack of oral care and clinical care. The aim was to carry out a systematic review of the literature on the oral health status of hospitalized patients with mental disorders (MD). A systematic search of the literature was carried out in PubMed, according to the PRISMA statement methodology, through the MeSh health descriptors "Dental Caries" and "Mental Disorders" in February 2017. According to the different filters that were applied, 14 articles describing the oral health status were obtained - through the DMF-T index (teeth with cavities, teeth with restorations, missing teeth and teeth with necessary extraction)- of hospitalized patients with MD. The recognition of the importance of oral health by health professionals, carers and family members should be promoted; the oral cavity should be explored to determine the state of health in addition to instructing patients and support personnel in oral hygiene; mental health institutions should establish an intervention programme to eliminate oral infectious sites and then implement a multidisciplinary preventive programme to maintain oral health according to the MD diagnosis.

Prevalence of Dental Caries Among Costa Rican Male Students Aged 12-22 Years Using ICDAS-II / Prevalencia de caries en varones costarricenses escolarizados de 12 a 22 años utilizando ICDAS-II

ABSTRACT: Objective: Dental decay is a public health challenge in Low- and Middle- Income Countries, particularly for young people, often confronted to healthcare access barriers. The aim of this study was to determine the prevalence and severity of dental caries among young male students in Costa Rica. Study design: A cross-sectional study was performed in 428 Costa Rican male students aged 12-22 years, who attended a nonprofit social welfare boarding school in 2019. A clinical examination was ran by three calibrated examiners following the International Caries Detection and Assessment System (ICDAS-II). Results: Caries prevalence was estimated at 83%, 15% have lost a tooth due to dental decay, 61% have at least one filled tooth, 36% have at least one filled and decayed tooth. The most frequent caries lesions were codes 2-Inactive (46.7%) and code 1-Inactive (23.8%). DMFT indicated a mean index using ICDAS-II 1-6>0 codes of 7.89. Using ICDAS-II 3-6>0 as threshold, the index decreases to 3.94. Finally, the lower and upper first permanent molars were found to be the most affected teeth. Conclusions: Dental caries experience represents a significant public health burden in young people, requiring better access to public dental healthcare.

Evaluation of Pediatric Patient's Age, Behaviors, and Reasons for the First Dental Visit in Edirne, Turkey: a Cross-Sectional Study / Evaluación de la edad, los comportamientos y las razones de la primera visita dental del paciente pediátrico en Edirne, Turquía: un estudio transversal

ABSTRACT: Oral and dental health are vital parts of general baby health, and early dental visits provide significant prevention-focused intervention and parental counseling regarding oral health. Evaluating the age and main complaints of children is therefore important during their first dental visit (FDV). The purposes of this study were to determine the age, reason for the visit, behavioral response, and caries status at the FDV and to evaluate the factors affecting these parameters. Parents of 325 pediatric patients (159 males; 166 females; mean age 7.20±2.78 years) at their FDV were asked to fill out a questionnaire requesting sociodemographic information and their child's medical history, brushing habits, and reasons for attending dental consultation. The decayed-missing-filled-teeth (dmft/DMFT) scores were also recorded. The child's behavioral responses during the FDV were evaluated according to Frankl's Behavior Rating Scale (FBRS). Higher maternal education level and dmft/DMFT score were associated with earlier FDV age. The most common reason for the FDV was dental caries in 33.5% of patients, followed by toothache (29.5%). Most of the children showed positive behavior (46.7%), with positive behavior affected by age and negative behavior affected by the dmft/DMFT score and distance from home. The mean dmft/ DMFT score was 8.1±4.4 and was negatively affected by toothbrushing frequency and family income. These study results indicate that Turkish children living in Edirne present at a late age for the FDV. Raising awareness in terms of dental health care among parents is important to ensure that children attend their FDV at an early age.

RESUMEN: La salud oral y dental son partes vitales de la salud general del bebé, y las visitas dentales tempranas brindan una importante intervención centrada en la prevención y asesoramiento a los padres sobre la salud bucal. Por lo tanto, evaluar la edad y las principales quejas de los niños es importante durante su primera visita al dentista (FDV por sus siglas en inglés). El propósito de este estudio fue determinar la edad, motivo de visita, respuesta conductual y estado de caries en la FDV y evaluar los factores que afectan estos parámetros. A los padres de 325 pacientes pediátricos (159 hombres; 166 mujeres; edad media 7,20±2,78 años) en su FDV se les pidió que llenaran un cuestionario solicitando información sociodemográfica y el historial médico de su hijo, hábitos de cepillado y motivos de presentación a la consulta dental. También se registraron las puntuaciones de dientes cariados-faltantes-obturados (dmft/DMFT). Las respuestas conductuales del niño durante la FDV se evaluaron de acuerdo con la escala de calificación de conducta de Frankl (FBRS). Un mayor nivel de educación materna y una puntuación de dmft/DMFT se asociaron con una edad más temprana de la FDV. La causa más común de la FDV fue la caries dental en el 33,5% de los pacientes, seguida del dolor de muelas (29,5%). La mayoría de los niños mostró un comportamiento positivo (46,7%), con un comportamiento positivo afectado por la edad y un comportamiento negativo afectado por el puntaje dmft/DMFT y la distancia del hogar. La puntuación media de dmft/DMFT fue de 8,1±4,4 y se vio afectada negativamente por la frecuencia de cepillado de dientes y los ingresos familiares. Los resultados de este estudio indican que los niños turcos que viven en Edirne se presentan a una edad avanzada para la FDV. Es importante concienciar a los padres sobre el cuidado de la salud dental para garantizar que los niños asistan a su FDV a una edad temprana.

Especificidad y Sensibilidad de Sistema ICDAS TM versus Índice COPD en la Detección de Caries / Specificity and Sensitivity of the ICDAS TM System versus the DMFT Index in Caries Detection

RESUMEN: La caries dental no tratada es la enfermedad crónica más frecuente en adultos y la caries no tratada en dientes temporales es la décima enfermedad crónica más frecuente. En Chile los adultos presentan un COPD promedio entre 3,76 - 22,16, pero los estudios no son en población representativa y no existen estudios comparativos entre ceod/ COPD e ICDASTM. A nivel mundial, su prevalencia puede alcanzar el 100 % de la población estudiada. Se buscará evaluar si existen diferencias en la sensibilidad y especificidad en la detección de caries utilizando ICDASTM y ceod/COPD. Se realizó una revisión sistemática cualitativa realizando una búsqueda sobre los índices de caries ceod/COPD y sistema ICDASTM, tanto en Chile como a nivel mundial, en las bases de datos Medline, ClinicalKey y SciELO encontrando 3.581, de ellos, 21 se leyeron por completo y 14 cumplieron nuestros criterios. La sensibilidad y especificidad es mayor con ICDASTM que con el índice ceod/COPD y entrega hasta un 43 % más información al detectar lesiones no cavitadas, pero necesita de mayor tiempo para su realización y más recursos al utilizar luz, aire comprimido y una profilaxis previa al examen. Capacitaciones previas, conocimientos y experiencia en ICDASTM son fundamentales para el mejor resultado, estudios demostraron que mientras mayor experiencia, la sensibilidad y especificidad aumentaba a diferencia del índice ceod/COPD. Se deben realizar más estudios comparativos entre ambos índices e incluir ICDASTM en niños por su capacidad de detectar lesiones no cavitadas las cuales son las más prevalentes en dientes temporales.

ABSTRACT: Untreated dental caries is the most frequent chronic disease in adults and untreated caries in primary teeth is the tenth most frequent chronic disease. In Chile, adults have an average DMFT between 3.76-22.16, but the studies are not in a representative population and there are no comparative studies between dmft/DMFT and ICDASTM. Worldwide, its prevalence can reach 100 % of the population studied. The objective of the study was to evaluate if there are differences in the sensitivity and specificity in the detection of caries using ICDASTM and dmft/DMFT. A qualitative systematic review was done, carrying out a search on the dmft/DMFT index and the ICDASTM system, both in Chile and worldwide, in the Medline, ClinicalKey and SciELO databases, finding 3,581, of which, 21 were read completely and 14 met the inclusion and exclusion criteria. The sensitivity and specificity is greater with ICDASTM than with the dmft/DMFT index and delivers up to 43 % more information when detecting non-cavitated lesions, but it needs more time for its realization and more resources because it needs to use light, compressed air and prophylaxis before the examination. Previous training, knowledge and experience in ICDASTM are fundamental for the best results. Studies showed that the greater the experience, the sensitivity and specificity increased, unlike the dmft/DMFT index. More comparative studies should be conducted between both indexes and include ICDASTM in children for their ability to detect non-cavitated lesions, which are the most prevalent in temporary teeth.

Oral Health Status of South-Eastern Iranian Children with Acute Lymphoblastic Leukemia.

Acute leukemia is characterized by the progressive excessive production of leukocytes in the bone marrow as well as the arrival of immature cells into the peripheral blood. The present study aimed to evaluate the oral hygiene status in patients with acute leukemia.METHODSThe present study included 50 ALL patients referred to the affiliated oncology centers of Kerman University of Medical Sciences from April to December 2015 and 52 healthy children. Data collected from the oral examination included the DMFT/dmft and plaque indexes and the presence of mucositis. Information about the diseases, blood test results, the patients’ age, and the type of drug was obtained from medical records. Data was analysed through SPSS software, T-test and Mann-Whitney test at a significance level of 0.05.RESULTSGrade 1 and 2 mucositis was observed in 6 (0.12%) and 1 (0.2%) patients respectively. The plaque index was significantly higher in patients than the healthy group (p= 0.033). The average missing teeth was higher in the ALL group, but it was not statistically significant. There were no statistically significant differences between the individuals with mucositis and those without mucositis (p=0.503). There were no statistically significant differences between the patients and healthy group in terms of the mean DMFT/dmft index.CONCLUSIONSThere were no statistically significant differences between the patients and healthy group in DMFT/dmft index. Statistically significant differences were seen between patients and healthy groups in terms of OHI-S index

The prevalence of dental caries in urban areas is lower than that in rural areas--analysis of changes in the epidemiological characteristics of caries in urban and rural areas / 口腔疾病防治

@#As one of the most common chronic diseases of the oral cavity, caries gradually accumulate over the lifetime and affect approximately 80% of the world population. The epidemiological characteristics of the disease are specific in terms of regional distribution, temporal distribution and population distribution. Caries prevalence and mean decayed, missing and filled permanent teeth (mean DMFT) scores are the most commonly used indexes in oral epidemiology. Caries prevalence is used to describe the frequency of caries over a certain period of time. In addition, DMFT scores reflect the severity of caries in the population. The caries prevalence and the severity of caries are assessed as part of a dynamic process. In developing countries, caries prevalence is higher among urban populations than among rural populations. Currently, the epidemic characteristics of caries in urban and rural areas are changing, and the caries prevalence of urban residents is lower than that of rural residents. This article is a chronological review of the Oral Health Epidemiological Surveys of China from 1983 to 2015, the Preventive Dentistry study and other related studies. It is concluded that the epidemic characteristics of caries in urban and rural areas in China have changed from a higher caries prevalence in urban areas compared to that in rural areas to a lower caries prevalence in urban areas compared to that in rural areas. Several factors, such as the dynamic development of differences in dietary habits, economic levels and access to oral medical resources of urban and rural residents might have led to changes in caries prevalence in urban and rural areas. The caries prevalence of rural residents has increased greatly, which indicates that the caries prevention efforts of the relevant departments should be focused more on rural areas in the future.

The Relation Between Decay Missing Filled-Teeth (DMF-t), Body Mass Index (BMI) with Salivary Human Beta-3 (HBD-3) Secretion in Children with Caries and Free Caries

@#Introduction: Dental caries in children is a major problem of mouth disease throughout the world, so too is there currently an increase in health problems in children due to obesity. Human Beta defensing(HBD) has been found in saliva and from several studies stated that HBD aside from being a broad-spectrum antimicrobial can act as an immunomodulator. The purpose of this study is to reveal whether there is a relationship between obesity and HBD-3 salivary concentration in caries patients and caries-free patients. Methods: This cross-sectional observational study was involved 62 children with caries and caries-free, aged 9-11 years, students at Qommarudin Islamic Boarding School, Gresik, East Java Indonesia. dental caries examination, carried out in accordance with World Health Organization (WHO) diagnostic criteria. Body mass index (BMI) was measured from the height and weight of individuals, HBD3 concentrations were tested with an ELISA kit from Bioassay Technology Laboratory (China) from saliva samples. Evaluate the results with the Kruskal Wallis test, followed by the Mann-Whitney test. The level of significance used in this statistical test was 0.05. Results: there was a relationship between BMI level and HBD-3 concentration in the caries group (p <0.05, p = 0.009) with a moderate level of association. but there was no significant relationship in the caries-free group (p> 0.05, p = 0.189). Conclusion: There was an association between BMI and HBD-3 salivary concentration in caries patients but there was no relationship in the caries-free group.

Correlation of decayed, missing and filled teeth with risk factors for dental caries in children attending outpatient department in tertiary care hospital

Background: Oral health is of vital importance to humans' general health. Despite the marked improvement in oral health, caries occurs in both developed and developing countries worldwide. The patient's age is important for determining caries risk. Special attention must be paid to children's oral health when deciduous teeth start erupting and occlusion has formed in 2 to 3-year-old children. To assess the correlation of decayed, missing and filled teeth (dmft/DMFT) with risk factors for dental caries in children and with knowledge, attitude, and practices of parents regarding dental caries.Methods: Cross-sectional study included 96 children with dental caries attending paediatric outpatient department of Government Stanley Medical College, Chennai, Tamil Nadu, India between 2018 March to November. Clinical evaluation, dmft score, and knowledge, attitude and practices of parents were assessed using pre-formed questionnaire.Results: Patients with high dmft score were found to have low practice score with the Pearson correlation coefficient(r) value -0.41 and P value was 0.01. Corresponding values of knowledge and attitude were not statistically significant. Children who nap/sleep with bottle/pacifier have increased risk (P value-0.01).Conclusions: An oral health risk assessment should be done periodically by Paediatrician who has regular contact with children for early identification of dental caries, to impart healthy oral practices and make them aware of preventive measures.

Do Braces Causes Caries?

Attaining improved aesthetics and proper occlusion are main reasons for commencing orthodontic treatment in any patient. However it is anticipated that orthodontic treatment increases the risk of carious lesions. Objective: To analyze prevalence of dental caries in relation to gender, age group, duration of orthodontic treatment and malocclusion type; and to assess oral hygiene and food habit practice in young orthodontic patients. Methods: A cross sectional study was done in 212 orthodontic patients (age range 11-30 years) having fixed appliance for at least six months duration. A survey form based on ‘Dentition Status & Treatment Need, WHO’ was used to depict DMFT Index and prevalence of dental caries. A questionnaire was used to assess the practice of oral hygiene measures and food habits of the orthodontic patients. The association between dental caries and gender, age group, duration of orthodontic treatment and malocclusion type were analyzed using chi-square test (p<0.05). Results: The prevalence of dental caries (DMFT) was 79.2% and mean DMFT value was 2.87 among orthodontic patients studied. Occurrence of dental caries among male and female patients was 69.44% and 60% respectively. Caries occurrence was highest in age group 16-20 years (72.22%), in more than 18 months treatment duration group (63.92%) and in Class I malocclusion group (68.38%). Similarly, 30.2% consume sweets foodstuff, 26.9% consume junk food and 14.2% consume snacks in between meals frequently. Conclusions: Fairly good proportion of orthodontic patients practice normal oral hygiene methods but very few use special oral hygiene measures. The study showed no association between dental caries occurrence and gender groups, age groups, duration of orthodontic treatment and malocclusion types.

Prevalencia de caries y factores asociados: estudio transversal en estudiantes de preparatoria de Chilpancingo, Guerrero, México / Prevalence of dental caries and associated risk factors: a cross-sectional study among preparatory (high school) students from Chilpancingo, Guerrero, Mexico

RESUMEN Introducción: La caries dental es el principal problema bucal que afecta a casi toda la población. La niñez y juventud son etapas cruciales para adquirir el hábito de higiene bucal adecuada y evitar daños a la cavidad oral en la edad adulta. Objetivo: Estimar la prevalencia de caries y los factores asociados en estudiantes de educación media superior de la Universidad Autónoma de Guerrero. Material y métodos: Estudio transversal en estudiantes de tres escuelas preparatorias de Chilpancingo, Gro. Un cuestionario autoadministrado preguntó sobre datos sociodemográficos, hábitos de higiene dental y la presencia de caries se definió a partir del índice CPOD (diente cariado, perdido y obturado). Se estimó razón de momios e intervalo de confianza de 95% como medida de asociación de los factores de riesgo. La estimación de las asociaciones en el análisis multivariado fue ajustada por el efecto del conglomerado. Resultados: La prevalencia de caries fue 91% (1,300/1,424), 18% (245/1,424) de los estudiantes tuvo obturados, 5% (67/1,424) tuvo una o más piezas dentales perdidas. El índice CPOD fue 5.31. Dos factores se asociaron con la presencia de caries: consumo de frituras, refrescos y golosinas (RMa 2.43, IC 95% 1.45-4.09), y la poca importancia dada a la salud bucal (RMa 1.48, IC 95% 1.01-2.18). Conclusiones: La prevalencia encontrada está en el rango de los reportes internacionales. Los dos factores asociados con la caries dental orientan qué acciones deben promoverse para el cuidado de la salud bucal en los estudiantes de educación media superior de la UAGro.

ABSTRACT Introduction: Tooth decay is the most important oral health problem affecting almost the whole population. Childhood and youth are crucial stages to acquire habits of proper oral hygiene to prevent damage to the oral cavity in adulthood. Objective: To measure the prevalence of dental caries and associated risk factors in students of middle education (preparatory school) at the Autonomous University of Guerrero (UAGro). Methods: Cross-sectional study including students from three preparatory schools (high schools) in Chilpancingo, Guerrero. A self-administered questionnaire collected sociodemographic and dental hygiene information; the presence of caries was defined according to the DMFT index (decayed, filled, and missing teeth). Odds ratio and 95% confidence intervals were estimated as measures of association for risk factors. Estimated associations in the multivariate analysis were adjusted by cluster effect. Results: The prevalence of caries was 91% (1,300/1,424); 18% (245/1,424) of students had filled teeth and 5% (67/1,424) had one or more missing teeth. A DMFT index score of 5.31 was found. Two factors were associated with the presence of caries: intake of snacks, sweets, and soft drinks (OR 2.43, 95% CI 1.45-4.09) and little attention to oral health (OR 1.48, 95% CI 1.01-2.18). Conclusions: The caries prevalence is in the range of international reports. The two factors associated with tooth decay should guide the actions to be implemented for promoting oral health among UAGro students of middle education.

The impact of a school-based tooth-brushing program on dental caries: a cross-sectional study

BACKGROUND@#Promotion of oral health in children is recognized as one of the components of health-promoting schools (HPSs). However, few studies have addressed supportive school environments for children's oral health. This study aimed to evaluate the status of dental caries in school children at HPSs, with the objective of examining the impact of a supportive school environment for oral health, considering the lifestyles of individual children and the socioeconomic characteristics of their communities.@*METHODS@#Data of 2043 5th-grade students in 21 elementary schools in Ichikawa city between 2008 and 2013 were analyzed. Children's oral health status was evaluated using the decayed, missing, and filled permanent teeth (DMFT) index. A self-reported lifestyle questionnaire, a survey of the school environment promoting tooth-brushing, and community socioeconomic characteristics derived from the National Census data were included in the analyses. Bivariate analyses were conducted to evaluate the children's DMFT status, and zero-inflated negative binominal (ZINB) regression was used to assess the relationships between DMFT and other variables.@*RESULTS@#Prevalence of dental caries in the permanent teeth of 5th-grade children (aged 10-11 years) was 33.3%, with a mean DMFT score (± SD) of 0.83 ± 1.50. According to multilevel ZINB regression analysis, children from schools with after-lunch tooth-brushing time showed a higher odds ratio (OR) for excess zero DMFT (OR = 1.47, 95% CI = 1.00-2.15, P = 0.049) as compared to those from schools without it. Neither bivariate analysis nor ZINB model analysis revealed any significant influence of children's gender or use of a toothpaste with fluoride.@*CONCLUSIONS@#The school-based environment supportive of oral health was significantly associated with a zero DMFT status in children. School-based efforts considering the socioeconomic characteristics of the area warrant attention even with declining prevalence of dental caries.

Spatial distribution of decayed and restored teeth in an adult population / Distribuição espacial de dentes cariados e restaurados numa população adulta

ABSTRACT Objective To analyze the spatial distribution of decayed and restored teeth in adults according to the Social Exclusion Index (SEI) and the proximity of public dental service. Methods: This ecological study used secondary data from an epidemiological survey of oral health and from the Piracicaba Research and Planning Institute (IPPLAP). The oral examinations of the DMFT index examined in households by a single examiner calibrated in 2011, by probability sampling, 248 adults (aged 20 to 64 years) representing the residents in Piracicaba-SP, Brazil. Data on social exclusion and health units with dental service were extracted from IPPLAP. We performed georeferencing of the census tracts selected by draw in the epidemiological survey and their respective districts, in addition to the health units with dental service in a radius of 500 m and 1000 m. Spearman's rank correlation coefficient was analyzed (p<0.05). Results: The smallest value of SEI, that is, the highest social exclusion, showed no correlation with decayed teeth (p=0.09), but had strong positive correlation with restored teeth (r=0.79; p<0.0001). Presence of public dental service in the vicinity of 500 m and 1,000 m showed no correlation, respectively, with the average number of decayed (p=0.07 and p=0.58) and restored (p=0.26 and p=0.56) teeth. Conclusion: Although the correlation between social exclusion and caries in adults was not observed, its case management, namely, the restored teeth, showed correlation with social inequalities. Presence of public dental service showed no correlation with components of caries experience evaluated in this study.

RESUMO Objetivo: Analisar a distribuição espacial dos dentes cariados e restaurados em adultos segundo o Índice de Exclusão Social (IEX) e a proximidade de serviço odontológico público. Metodologia: Este estudo ecológico utilizou-se de dados secundários de um levantamento epidemiológico de saúde bucal e do Instituto de Pesquisa e Planejamento de Piracicaba (IPPLAP). Os exames bucais do índice de dentes permanentes cariado perdidos e obturados (CPOD) examinou em domicílios por um único examinador calibrado em 2011, por amostragem probabilística, 248 adultos (20 a 64 anos) representativos dos residentes em Piracicaba-SP, Brasil. Os dados sobre exclusão social e as unidades de saúde com serviço odontológico foram extraídos do IPPLAP. Realizou-se o georreferenciamento dos setores censitários sorteados no levantamento epidemiológico e seus respectivos bairros, além das unidades de saúde com serviço odontológico em um raio de 500m e 1000m. Foi realizada a análise de correlação de Spearman (p<0.05). Resultados: O menor valor do IEX, ou seja, maior exclusão social, não apresentou correlação com dentes cariados (p=0,09), mas teve correlação positiva forte com dentes restaurados (r=0,79; p<0,0001). A presença de serviço odontológico público em proximidade de 500 e 1000m não apresentou correlação, respectivamente, com a média de dentes cariados (p=0,07 e p=0,58) e restaurados (p=0,26 e p=0,56). Conclusão: Apesar de não ser verificada correlação entre cárie e exclusão social em adultos, sua resolutividade, ou seja, os dentes restaurados apresentaram correlação com as desigualdades sociais. A presença de serviço odontológico público não apresentou correlação com os componentes de experiência de cárie avaliados nesse estudo.

The assesment of dental caries status among Students of school of dentistry, mnums / Шинэ санаа Шинэ нээлт

@#The most common oral disease is the dental caries, which is chronic transmissible, losing of hard tissue of teeth, and is very widespread in the world. The annual report of oral health survey of World Health Organization shows that 60-90% of population of developing countries was affected by dental caries. In the press review, the prevalence of dental caries and mean DMFt score among 18 years old were 74.4% and 4.04 in Mexico, 2009; 87.4% and 3.59 in Australia, 2003; and 88.9% and 7.15 in Japan, 1999. In Mongolia, the prevalence of dental caries and mean DMFt score among military students in 1987 were 83.3% and 3.7. There is a few studies among students of School of dentistry. Study population consisted of 115 students, who studied from 3rd to 5th course of School of Dentistry, Mongolian National University of Medical Sciences. Study was done by cross sectional study design from November to December, 2017. We checked up dental status of all students according to recommendation by WHO, 2013. The study was approved by the Medical Research Ethics Committee of the Mongolian National University of Medical Sciences and informed consent was obtained from all students (2017/3-04). The prevalence of dental caries among all students was 100% and mean dental caries score was 8.3±0.3 DMF/t, 3.7±0.3 D/t, 3.8±0.3 F/t, 0.8±0.1 M/t. When we assessed mean DMF/t score by student’s course, it was 8.5±0.5 among 3rd year students, 8.6±0.7 among 4th year and 7.9±0.5 among 5th year (p>0.05). Mean decayed teeth among 3rd, 4th, 5th course students were 4.5±0.5, 4.1±0.6 and 2.8±0.4, respectively (p<0.05). Mean filled teeth was 3.4±0.5, 3.5±0.6, 4.4±0.4 (p>0.05) and missed teeth was 0.7±0.2, 1.0±0.3, 0.7±0.2 (p>0.05) among students respectively above courses. All students, who participated in our study had dental caries and observed declining the number of decayed teeth during the study and the number of filled teeth was increasing.
