Cárie dentária em crianças que frequentaram um programa odontológico de atenção materno-infantil

The main goal of this study was to evaluate the prevalence of caries in children that participate in a dental program attending mothers and children in Teresina, Piauí, Brazil. A selection was made of 343 children of both genders, from 3 to 6 years of age. The mothers answered questionnaires and children were examined at the Infant Dental Clinic of the Federal University of Piauí. The epidemiological index dmft was applied and active white spot lesions were included. The SPSS for Windows program, version 11.1 was used and non-parametric tests carried out (Friedman and Kruskal-Wallis). An alpha error of 5% (0.05) was considered for the null hypothesis of false rejection, with a confidence interval of 95%. The results showed that 57.5% (197) of the children were breast-fed for a period longer than 12 months. The mean dmft index and percentages of caries-free children at the age of 3 was 1.86 (58.82%); at 4 years of age 1.94 (57.60%); at 5 years of age 1.98 (56.86%) and at 6 years of age 2.42 (42.55%). The decay component (d) was prevalent at all ages. When active white spot lesions were added to the dmft index, there was an increase of 7.2% for children who had caries activity and/or previous caries experience and 2.61% for those with dmft equal to zero. The daily consumption of fermentable carbohydrates and free demand breast-feeding were factors increasing caries activity. Dental follow-up after the program and the number of daily brushings were shown to be factors providing protection against caries . Based on the results, the authors were able to conclude that the program caused a positive impact on caries disease control, as the number of dental appointments kept influenced the dmft index values in a statistically significant manner.O objetivo do presente estudo foi avaliar o impacto apresentado por um programa de atenção materno-infantill na prevalência de cárie de crianças participantes. Foram selecionadas 343 crianças, de ambos os gêneros, nas idades de 3 a 6 anos. As mães responderam a questionários e as crianças foram examinadas em consultórios da clínica odontológica infantil da Universidade Federal do Piauí (UFPI). Foi aplicado o índice epidemiológico ceod com acréscimo de lesões de manchas brancas ativas. Os dados foram analisados pelo programa SPSS para Windows, versão 11,1 e realizados os testes não paramétricos (Friedman e Kruskal-Wallis). Considerou-se um erro alfa de 5% (0,05) para hipótese nula de falsa rejeição, com um intervalo de confiança de 95%. Os resultados mostraram que 57,5% (197) das crianças foram amamentadas ao seio por um tempo superior a 12 meses. A média do índice ceo-d e percentuais de crianças livres de cárie para a idade de 3 anos foi de 1,86 (58,82%); aos 4 anos, de 1,94 (57,60%); aos 5 anos, de 1,98 (56,86%) e aos 6 anos de 2,42 (42,55%). O fator cariado (c) foi prevalente em todas as idades. Quando foram acrescentadas ao índice ceo-d lesões de manchas brancas ativas, houve um aumento de 7,2% para crianças com atividade e/ou experiência anterior de cárie e de 1,72% para aquelas com ceod igual a zero. O consumo diário de carboidratos fermentáveis e a amamentação em livre demanda se apresentaram como fatores incrementais da atividade de cárie. O acompanhamento odontológico posterior ao programa e o número de escovações diárias demonstraram ser fatores de proteção contra a instalação da doença cárie. Baseados nos resultados, os autores puderam concluir que o programa provocou impacto positivo no controle da doença cárie, uma vez que o número de consultas freqüentadas influenciou nos valores do índice ceod de maneira estatisticamente significativa

Knowledge of oral health and practices among mothers attending a mother-child dental care program

O objetivo do presente estudo foi avaliar a assimilação e as práticas preventivas em saúde bucal adotadas por mães de crianças que freqüentaram um programa odontológico de atenção materno infantil. O Programa Preventivo para Gestantes e Bebês (PPGB) é um programa de extensão vinculado à Universidade Federal do Piauí (UFPI), que tem como meta a conscientização de gestantes e mães de crianças de zero a 36 meses para a adoção de hábitos favoráveis à obtenção de saúde bucal. Realizou-se uma seleção aleatória de fichas clínicas de crianças que haviam participado do PPGB e, através destas fichas, foram enviadas cartas às mães. Houve um retorno de 281 mães, as quais foram submetidas a entrevistas envolvendo os temas abordados pelo programa. Pelos resultados obtidos, pôde-se concluir que as mães freqüentadoras do PPGB detêm um bom nível de informação e adotam, no âmbito familiar, práticas de saúde favoráveis ao controle e prevenção de doenças bucais.This study assesses the assimilation of knowledge and preventive practices in oral health among the mothers of children assisted by a mother-child dental care program. The Preventive Program for Pregnant Mothers and Babies (PPPMB) is an extension project run by the Piauí Federal University (UFPI), whose goal is to make pregnant women and mothers of children from zero to 36 months old more concerned about habits fostering oral health. After a random selection of clinical record cards for children who had participated in this Program, letters were sent to their mothers. Feedback was received from 281 mothers, who responded through interviews that included questions on matters addressed by the Program. The findings indicate that mothers attending this Program were properly informed, adopting hygienic practices in their families that underpin the control and prevention of oral diseases

Salivary Fluoride Levels after Use of High-Fluoride Dentifrice

The aim of the study was to evaluate salivary fluoride (F) availability after toothbrushing with a high-F dentifrice. Twelve adult volunteers took part in this crossover and blind study. F concentration in saliva was determined after brushing with a high-F dentifrice (5000 µg F/g) or with a conventional F concentration dentifrice (1100 µg F/g) followed by a 15 mL distilled water rinse. Samples of nonstimulated saliva were collected on the following times: before (baseline), and immediately after spit (time = 0) and after 1, 2, 3, 4, 5, 10, 15, 20, 30, 45, 60, 90, and 120 min. F analysis was performed with a fluoride-sensitive electrode and the area under curve of F salivary concentration × time (µg F/mL × min−1) was calculated. At baseline, no significant difference was found among dentifrices (P > 0.05). After brushing, both dentifrices caused an elevated fluoride level in saliva; however salivary F concentration was significantly higher at all times, when high-F dentifrice was used (P < 0.01). Even after 120 min, salivary F concentration was still higher than the baseline values for both dentifrices (P < 0.001). High-F dentifrice enhanced the bioavailability of salivary F, being an option for caries management in patients with high caries risk

Topography of Primary Molar Pulp Chamber Floor: A Scanning Electron Microscopy and Micro-Computed Tomography Analysis

Objective: To determine in vitro the frequency, shape, type, diameter, and patency of accessory canals in the primary molars pulp chamber floor. Material and Methods: Sixteen healthy primary molars were evaluated by micro-computed tomography and scanning electron microscopy. Descriptive analyses of the frequency, shape (round, oval, or irregular), type (blind, true, or hidden), patency and diameter of the accessory canals were performed. Results: Half of the teeth presented accessory canals, 62.5% of which were located in the upper molars and 37.5% in the lower molars. The most frequent shape was irregular. In three-dimensional analysis, blind accessory canals (12.5%) and with patency (18.7%) of the teeth were observed. The average accessory canal diameter was 51.97 µm (± 26.03 µm). Conclusion: Upper molars showed a higher frequency of accessory canals with larger diameters. The irregular shape was the most frequent. 18.7% of accessory channels showed patency

Dentin Thickness of Pulp Chamber Floor in Primary Molars: Evaluation by Cone-Beam Computed Tomography

Objective: Use cone-beam computed tomography (CBCT) images to evaluate the dentin thickness of the pulp chamber floor in primary molars. Material and Methods: Cross-sectional study, conducted with CBCT images of teeth of children.&nbsp; Primary molars with preserved pulp chamber floor were included. The dentin thickness of the pulp chamber floor in the primary molars was measured linearly in CBCT cross-sections. Data were descriptively analyzed and the Mann-Whitney test was applied (p&lt;0.05). Results: 27 CBCT exams and 123 primary molars of children aged 4 to 13 years were analyzed; the majority was female (52.0%). In maxillary molars, the median dentin thickness was 1.50 (0.6–2.2) mm in the first and 1.65 (0.6–2.3) mm in the second (p=0.049) molars. In mandibular molars, the median was 1.20 (0.3–1.7) mm in the first and 1.60 (1.0–2.2) mm in the second (p&lt;0.001) molars. Children aged 4 to 8 years showed less dentin thickness (p&lt;0.001). Conclusion: The median dentin thickness of the pulp chamber floor in primary molars was 1.50 mm, ranging from 0.3 to 2.3 mm. Less dentin thickness was associated with younger children, teeth in the mandibular arch, and first molars

Impact of dental fluorosis on the quality of life of children and adolescents

INTRODUCTION: Dental fluorosis is a disturbance of high prevalence caused by the ingestion of fluoride ions present mainly in toothpaste. Preventive measures to avoid it are still controversial. Thus, knowing the impact that fluorosis can cause on the population's quality of life it is important for planning public health policies.OBJECTIVE: To evaluate the impact of dental fluorosis on the quality of life of children and adolescents.MATERIAL AND METHOD: We studied 300 subjects aged 8 to 12 years divided into 4 groups: children (8-10 years) and adolescents (10 to 12 years) with and without fluorosis. The diagnosis of fluorosis was performed according to the index Thylstrup and Fejerskov and quality of life was evaluated using Child Perceptions Questionnaire 8-10 and 11-14. The socio-demographic characteristics of the patients were also evaluated. For inclusion in the sample, selected patients should present eight permanent incisors with crowns fully erupted. Patients who had extensive restorations, fractured teeth, other dental enamel defects and who wore braces were excluded.RESULT: Fluorosis was present in 64.7% of the patients analyzed and in most cases (80.3%) was mild or very mild. In children, the average overall score of the questionnaire was 15.9 for the group without fluorosis and 18.3 for the group with fluorosis (p = 0.255). The teenagers' score in the group without fluorosis was 26.1, while the group with fluorosis was 22.7 (p = 0.104).CONCLUSION: Dental fluorosis caused impact on the quality of life of the population analyzed only in the functional domain
