Factors associated with the need for a complete denture in one arch or both arches among the elderly population.

This study aimed to identify factors associated with the need for complete dentures in one dental arch or both, among the elderly population. The cross-sectional household study was conducted with a representative sample of elderly people (65 years or older) in the state of São Paulo, Brazil, in 2015. The dependent variable was the need for complete dentures (in one arch or both), and independent variables were socioeconomic and demographic conditions, social capital, self-perception of oral health and access to dental services. Simple and multinomial logistic regression models tested effect measures (p < 0.05). A total of 5,948 elderly people participated. Results indicated that those with greater chances of needing a complete denture in one arch were male (OR = 1.54; CI95%:1.04-2.29), with fewer household goods (OR = 2.25; CI95%:1.50-3.38), lower monthly household income: R$501-1500 (OR = 3.44; CI95%:1.27-9.35), R$1501-2500 (OR = 4.11; CI95%:1.50-11.27), R$2501-4500 (OR = 2.76; CI95%:1.10-6.95), self-reported need for a complete denture (OR = 4.75; CI95%:3.08-7.35), ≥3 years since last dental appointment (OR = 1.80; CI95%:1.06-3.05), and dissatisfaction with last dental appointment (OR = 1.80; CI95%:1.06-3.05). There were more chances of the need for complete dentures in both arches among older elders (OR = 1.44; CI95%:1.06-1.88), with lower monthly household income: R$ < 501 (OR = 4.45; CI95%:1.71-11.60), R$501-1500 (OR = 4.01; CI95%:2.14-7.51), R$1501-2500 (OR = 2.95; CI95%:1.64-5.32), < 3 years of education (OR = 1.45; CI95%:1.13-1.85), feeling unhappy (OR = 2.74; CI95%:1.35-5.57), self-reported need for a complete denture (OR = 8.48; CI95%:5.75-12.50), dissatisfaction with their mouth (OR = 2.38; CI95%:1.64-3.46), ≥3 years since last dental appointment (OR = 4.28; CI95%:2.85-6.43), and dissatisfaction with last dental appointment (OR = 4.28; CI95%:2.85-6.43). The several dimensions of the determinants of the need for a complete denture reflect the influence of both demographic and socioeconomic aspects, social capital, self-perception of oral health and access to dental services.

Tooth loss in adults: factors associated with the position and number of lost teeth.

OBJECTIVE: To evaluate the factors associated with tooth loss in adults from the position and number of teeth lost in the dental arches. METHODS: This is a cross-sectional, population-based study with adults participating in the epidemiological survey of oral health of São Paulo in 2015. The outcome of the study was tooth loss, assessed by the proposed classification, namely: I) lost up to 12 back teeth; II) lost up to 12 teeth (including front teeth); and III) lost more than 12 teeth. A four-block analysis was conducted, supported by a conceptual theoretical model adapted for tooth loss. For the multinomial logistic regression, "individuals who did not lose teeth due to caries or periodontal disease" was used as reference (p < 0.05). RESULTS: Of 6,051 adults evaluated, 25.3% (n = 1,530) were classified in category I, 32.7% (n = 1,977) in II, 9.4% (n = 568) in III, and 1.9% (n = 117) were edentulous. Lower income and schooling, the perception of need for treatment and the last appointment motivated by routine, pain or extraction were associated with tooth loss, regardless of the classification. The negative evaluation of the dental service was associated with individuals who lost up to 12 teeth, both front and back. The presence of women and periodontal pocket were associated with tooth loss of up to 12 teeth, including front, and more than 12 teeth. Caries were associated with adults who lost up to 12 teeth, including front teeth. CONCLUSION: The proposed classification allowed the identification of differences between the associated factors. Thus, the need to consider such classification in future studies is evident.

COMPORTAMENTO CLÍNICO DE RESINAS COMPOSTAS EM DENTES POSTERIORES - REVISÃO SISTEMATIZADA DA LITERATURA / Clinical Behavior of Composite Resins in Posterior Teeth - Systematic Literature Review

Dentre os materiais restauradores diretos empregados na atualidade, as resinas compostas constituem a primeira opção para a restauração de dentes posteriores quando a estética é requisitada. O Objetivo deste estudo é revisar a literatura de forma sistemática, sobre a avaliação do comportamento clínico de restaurações de resina composta em dentes posteriores. Onze artigos que tratavam sobre o tema, publicados em periódicos científicos indexados no período de 2005 a 2015, foram selecionados após pesquisa bibliográfica nas seguintes bases de dados: LILACS, MEDLINE, BBO e SCIELO; utilizandose os descritores combinados: Restaurações diretas, Resinas compostas, Avaliação clínica, Dentes posteriores, Materiais restauradores. Deles foram retiradas as principais informações contidas no texto, a respeito das características de avaliação desses materiais em estudos clínicos científicos. Sete artigos relataram desempenho clínico aceitável para as restaurações avaliadas, observando-se que alguns tipos de cavidades são mais factíveis a falhas após a realização das restaurações. A utilização de resinas compostas em dentes posteriores apresenta aceitabilidade e sucesso clínico. Suas falhas são atribuídas principalmente às propriedades do próprio material restaurador e à sensibilidade da técnica restauradora, sendo mais comuns em restaurações de cavidades tipo classe II.

Among the restorers direct employees today materials, composites are the first choice for restoring posterior teeth when aesthetics are required. The aim of this study is to review the literature in a systematic way on the evaluation of the clinical behavior of composite restorations in posterior teeth. Eleven articles that dealt on the subject, published in scientific journals indexed in the period from 2005 to 2015, were selected after literature search in the following databases: LILACS, MEDLINE, BBO and SCIELO; using the combined descriptors: Direct Restorations, Composite resins, Clinical, later teeth, restorative materials. Of them were taken key information contained in the text, regarding the evaluation of characteristics of these materials in scientific clinical studies. Seven articles reported acceptable clinical performance for the evaluated restorations, noting that some types of cavities are more feasible fault after the completion of the restorations. The use of composite resins in posterior teeth presents acceptability and clinical success. Your failures are attributed mainly to the properties of the restorative material itself and the sensitivity of restorative technique, being more common in restorations of class II cavities.

Evaluation of acidulated dentifrice influence on fluoride releasing from glass-ionomer cements / Avaliação da influência de creme dental acidulado na liberação de flúor de cimentos de ionômero de vidro

Objetivo: Avaliar a influência da exposição a um creme dental acidulado sobre a liberação de flúorde Cimentos de Ionômero de Vidro (CIV). Material e Métodos: Confeccionou-se 27 corpos de prova divididos em 3 grupos: G1 (Maxion - R), G2 (KetacMolar 3M/ESPE) e G3 (Vittremer 3M/ESPE), subdividido em subgrupos (n = 3): A (exposição ao creme dental flúor acidulado – pH 4,5 / 7 h / 37ºC), B (exposição ao creme dental fluoretado não acidulado / 7 h / 37 ºC) e C (controle - exposição à saliva artificial). Após exposição aos cremes dentais,os corpos de prova foram imersos em saliva artificial e aferidas a liberação de flúor nos períodos de tempo:1 e 14 dias. Os dados obtidos foram submetidos a análise de variância, utilizando o pacote SPSS (Statiscal Package for Social Science). Aplicou-se seo Teste ANOVA com 5% de probabilidade, para comparação das médias e do comportamento de cada material. Resultados: A exposição ao creme dental ácido apresentou valores de liberação de flúor (ppm/mm2) que variaram, em suas médias, de 1 e 14 dias:G1A (0,269 a 0,204); G2A (0,394 a 0,038); G3A(0,080 a 0,123). Foi estatisticamente significante a relação entre os subgrupos para G1 em T1 e G3 emT1 e T14. Conclusão: a exposição ao creme dental acidulado influenciou positivamente a liberação de flúor do CIV híbrido testado e não impactou a liberação deste íon nos CIVs convencionais.

Objectives: To evaluate the acidulated dentifrice influence on fluoride releasing from glass-ionomercements. Methods: 27 specimens were constructed,divided into 3 groups: G1 (Maxion - R), G2 (KetacMolar 3M/ESPE) and G3 (Vittremer 3M/ESPE), and subdivided into 3 subgroups (n = 3): A (exposure to acidulated fluoride dentifrice – pH 4.5 / 7h /37 ºC), B (exposure to non-acidulated fluoridedentifrice / 7h / 37 ºC), C (control - exposure toartificial saliva). After exposing, the specimens were immersed into artificial saliva and the fluoridere leasing measured at the following time periods:1 to 14 days. Data were subjected to analysis ofvariance using the Statistical Package for Social Science (SPSS). ANOVA test was applied with levelof significance of 5% to compare the means and the behavior of each material. Results: The exposure to acidulated dentifrice showed fluoride releasing means values (ppm/mm2) that varied from 1 and 14days : G1A (0.269 to 0.204); G2A (0.394 to 0.038);G3A (0.080 to 0.123). The relationship among the G1 subgroups at T1 and G3 subgroups at T1and T14 was statistically significant. Conclusion:The acidulated dentifrice positively influenced onfluoride releasing of hybrid GIC but not on that ofconventional GICs.
