OCORRÊNCIA DE PERDA DENTÁRIA ENTRE OS USUÁRIOS DA ESTRATÉGIA DE SAÚDE DA FAMÍLIA DO MUNICÍPIO DE CAMPINA GRANDE - PB

Objective: To evaluate the occurrence of tooth loss among users of the Family Health Strategy in Campina Grande-PB. Method: The non-probabilistic sample was composed by 204 users of FHUs, aged 18 years or more. Data collection instrument used was a specific form, containing open, closed, multiple choice and dichotomous questions. The variables studied were sex, age, tooth loss, type of missing tooth and reason for losing. The oral examination was performed by a single examiner, under natural light at the FHU environment, using only disposable wooden spatulas. Data were analyzed using the SPSS (Statistical Package for Social Sciences) version 13.0, and presented by means of descriptive statistics (absolute and percentage distributions). Results: 87.7% of the sample was found to present teeth loss, and molars predominated (69.3%). Individuals aged over 56 years had the highest percentage of teeth lost (53.1%). Men had a higher percentage of tooth loss (34.4%) compared to women. Decay was the main reason for tooth extraction (47.3%). Conclusion: Tooth loss prevalence was proven to be high, affecting mainly males and above 56 years of age. Posterior teeth were the most frequently lost, being tooth decays the main cause. DESCRIPTORS: Prevalence. Tooth Loss. Family Health Program.

EFEITO DOS SUCOS DE FRUTAS INDUSTRIALIZADOS NA MICRODUREZA DO ESMALTE DENTAL PERMANENTE

Objective: To analyze in vitro the endogenous pH and the effect of industrialized fruit juices on the microhardness of permanent tooth enamel. Material and Method: Sample was composed of 10 beverages from two commercial brands and different flavors. Experimental groups were formed by selecting the beverages with lower and higher pHs according to the brands. Twenty-five specimens were prepared from human third molars and randomly assigned into five groups: G1: Ades Uva®, G2: Ades Morango®, G3: Kapo Uva®, G4: Kapo Laranja® and G5: Control (distilled water). Vickers microhardness was analyzed before (T1) and after (T2) the demineralization-remineralization cycles by applying a 100 g load during 15 seconds. The specimens were immersed in the juices during 1 minute, followed by 3 minutes in artificial saliva. Wilcoxon test was used for statistical analysis with 5%significance level and 95% confidence level. Results: All beverages presented pH values below the critical value of 5.5 for enamel demineralization, varying from 3.53 to 3.93. Microhardness analysis showed statistically significant difference (p=0.04) in all experimental groups, the largest reduction was observed in G1 (190.67). Conclusion: All beverages promoted a significant decrease in permanent enamel microhardness, being considered as potentially erosive under the conditions of this study. DESCRIPTORS Hardness Tests.

AVALIAÇÃO DO POTENCIAL EROSIVO DE BEBIDAS À BASE DE SOJA

Aim: To evaluate the endogenous pH, titratable acidity (TA) and total soluble solid content (TSSC) of soy-based drinks. Methods: Twelve samples of soy-based drinks (9 juices and 3 milks) were analyzed. The endogenous pH was evaluated by potentiometry, titratable acidity was evaluated by the addition of 0.1N KOH increments to the mouthwashes, and TSSC readings were performed by Brix refractometry using the Abbe refractometer. The soy-based drinks were evaluated with 3 measurements for each sample, and the mean of the three values was recorded. Data were collected by a single examiner, recorded in study-specific charts and were analyzed statistically by Epi-Info software (mean and standard deviation). Results: All soy-based juices showed pH below the critical value of 5.5. Ades Abacaxi® presented the lowest pH (3.94), while Sollys Original® presented the highest pH (7.15). Regarding the titratable acidity, the lowest mean (0.04) to Ades Original® while Sollys Uva® showed the highest mean (0.33). The lowest TSSC (8.0) was to Ades Original®, while the highest TSSC (15.0) to Mais Vita Uva®. Conclusion: The industrialized soy-based juices evaluated in this study have a high erosive potential and may be potentially erosive to the dental tissues. DESCRIPTORS: Soybeans / adverse effects.

Lesões Cervicais não cariosas: um panorama atual

A perda progressiva da estrutura dentaria associada a ocorrencia de lesoes cervicais nao cariosas tem-se mostrado um problema cada vez mais frequente na pratica odontologica contemporânea, uma vez que o aumento da expectativa de vida tem favorecido a manutencao da denticao natural. Dessa forma, o numero de pessoas que expoem seus dentes por um maior periodo de tempo aos multiplos fatores etiologicos relacionados a perda progressiva e nao cariosa das estruturas dentais tambem tem aumentado, fato que pode resultar em complicacoes esteticas e funcionais. Portanto, este trabalho destina-se a realizar uma revisao de literatura acerca dos fatores etiologicos, classificacao, caracteristicas clinicas e opcoes terapeuticas para as lesoes cervicais nao cariosas, possibilitando aos cirurgioes-dentistas o estabelecimento do diagnostico diferencial, de condutas preventivas e de tratamento.

Oral health habits, prevalence of dental caries and dental erosion in adolescents

Objective To assess oral hygiene habits, and prevalence of dental caries and erosion in adolescents of Campina Grande, Paraíba, Brazil. Methods Cross-sectional study with random cluster sampling involving 201 15-year-old schoolchildren. Oral health habits were obtained through questionnaire, and socioeconomic data, by means of interviews. The DMFT index was adopted to determine the prevalence of caries and that proposed by O’Sullivan, to assess dental erosion. Data were analyzed using the Statistical Package for Social Sciences (SPSS) version 18. A 5% significance level was adopted. Results All subjects reported using toothbrush and toothpaste, 50.7% reported dental flossing, and association was found between sex and use of mouthwash (p <0.05). Regarding dental caries, the mean DMFT was 3.67 and 51.7% had DMFT lower than or equal to 3. For dental erosion, 18.4% of the sample had erosive lesions, predominantly enamel lesions (92%). Conclusion The use of dental floss was low and adolescents revealed unsatisfactory index. The DMF-T value was moderate and lower than that reported for the Brazilian age group. The prevalence of dental erosion was high, with predominance of enamel lesions. Indexing terms: Dental caries. Oral hygiene. Tooth erosion.

Access to Oral Health Services in Areas Covered by the Family Health Strategy, Paraíba, Brazil

Objective: To evaluate access to oral health services and associated factors in areas covered by the Family Health Strategy. Material and Methods: This is a population-based study with a systematic random sample of 759 individuals aged ≥ 06 years of a municipality in northeastern Brazil. Data on socio-economic and demographic conditions, tooth pain severity in the last six months and issues related to access to oral health services were collected. Data were analyzed using Pearsons chi-square test and Poisson regression analysis, considering 5% significance level. All tests were performed using the Statistical Package for Social Sciences software (SPSS) version 18.0. Results: 61.7% of individuals had access to dental services, 53.5% of them in the public sector. Through Poisson multivariate regression, individuals more likely to have full access were students (PR: 3.085, 95% CI 1.75-5.43), adolescents (PR: 2.297, 95% CI 1.30-4.04), adults at reproductive phase (PR: 2.127, 95% CI 1.24-3.62) and those with toothache in the last six months (PR: 1.314, 95% CI 1.08-1.59). Illiterates and individuals with up to complete elementary school were associated with lower likelihood of having full access to oral health services. Conclusion: More than half of the sample had access to oral health services, being higher in the public sector than in the private sector. Having full access to oral health services was associated in the multivariate model with age, education and toothache in the last six months.
