Relationships of beta-blockers and anxiolytics intake and salivary secretion, masticatory performance and taste perception

OBJECTIVE Assess the influence of salivary flow on physiological parameters of the stomatognathic system in patients who take beta-blockers or anxiolytic medications. DESIGN Sixty patients were divided into three groups based on the following criteria: Group 1, control (n=20; no use of medication); Group 2, use of antihypertensive beta-blockers (n=20); and Group 3, use of benzodiazepine anxiolytics (n=20). Salivary flow was assessed by determining stimulated and non-stimulated flow/minute. The quantification of the sense of taste was determined on a visual analogue scale (VAS) using solutions of 0.9% NaCl (salty), 50% sucrose (sweet), 20% unsweetened coffee (bitter) and 4.2% vinegar (sour). The DMFT index (number of decayed/missing/filled teeth) was determined by a calibrated examination, following the criteria of the World Health Organization (WHO). Masticatory performance was assessed with an Optosil comminution test and Rosim-Ramler equation. RESULTS The results did not reveal a significant correlation between salivary flow and masticatory performance (p>0.05). We observed significant decreased non-stimulated salivary flow for Group 2 (p=0.05) when compared to controls. However, taste perception was not influenced by salivary secretion amongst groups. Furthermore, we observed a significant negative correlation between non-stimulated salivary flow and DMFT in Group 1 (p=0.02; r=-0.52). CONCLUSIONS Patients under beta-blockers therapy presented reduced non-stimulated salivary flow when compared to controls, without influencing the sense of taste or masticatory performance. The use of anxiolytics did not affect salivary flow and taste perception in the studied sample.

Geographic Information Systems (GIS) in Assessing Dental Health

The present study investigated the distribution profile of dental caries and its association with areas of social deprivation at the individual and contextual level. The cluster sample consisted of 1,002 12-year-old schoolchildren from Piracicaba, SP, Brazil. The DMFT Index was used for dental caries and the Care Index was used to determine access to dental services. On the individual level, variables were associated with a better oral status. On the contextual level, areas were not associated with oral status. However, maps enabled determining that the central districts have better social and oral conditions than the deprived outlying districts.

Estimate of DMFT index using teeth most affected by dental caries in twelve-year-old children

The objective of the study was to develop regression models to describe the epidemiological profile of dental caries in 12-year-old children in an area of low prevalence of caries. Two distinct random probabilistic samples of schoolchildren (n=1,763) attending public and private schools in Piracicaba, Southeastern Brazil, were studied. Regression models were estimated as a function of the most affected teeth using data collected in 2005 and were validated using a 2001 database. The mean (SD) DMFT index was 1.7 (2.08) in 2001 and the regression equations estimated a DMFT index of 1.67 (1.98), which corresponds to 98.2% of the DMFT index in 2001. The study provided detailed data on the caries profile in 12-year-old children by using an updated analytical approach. Regression models can be an accurate and feasible method that can provide valuable information for the planning and evaluation of oral health services.O objetivo do estudo foi desenvolver modelos de regressao para delinear o perfil epidemiologico da carie dentaria em localidade com baixa prevalencia de carie aos 12 anos de idade. Foram examinadas duas amostras probabilisticas (n=1.763) de individuos de escolas publicas e privadas de Piracicaba,(SP). Dados sobre os dentes mais afetados foram coletados em 2005 e validados utilizando um banco de dados (2001). A media (dp) do CPOD foi de 1,7 (2,08) em 2001 e os modelos de regressao desenvolvidos estimaram um CPOD de 1,67 (1,98) em 2005, o qual representa 98,2% do CPOD em 2001. Os resultados apresentaram detalhes do perfil da carie dentaria aos 12 anos, usando uma abordagem analitica atual. Os modelos de regressao poderiam ser considerados como uma forma acurada e factivel no auxilio do planejamento e avaliacao dos servicos em saude bucal.
