Dental pain in Brazilian schoolchildren: a cross‐sectional study

International Journal of Paediatric Dentistry 2013; 23: 131–137 Aim. To estimate the prevalence, intensity and associated factors of dental pain in 7‐ and 8‐year‐old schoolchildren in a Southern Brazilian city. Design. A cross‐sectional study was carried out involving a representative sample (n = 401) of schoolchildren of Tubarão, Brazil. The data were obtained through oral examinations, following WHO criteria. Dental pain was analysed using a specific questionnaire developed to measure it. Prevalence and intensity of spontaneous pain and pain caused by cold and hot food and liquids were analysed. Association studies were carried out using chi‐square test followed by nonconditional multiple logistic regression analysis to test for independence of association between outcomes and explanatory variables. Results. The prevalence of spontaneous dental pain and dental pain caused by cold and hot food and liquids was 31.7 and 28.1%, respectively. Females and schoolchildren who had visited the dentist at least once showed statistically higher prevalence of spontaneous pain and pain caused by cold and hot food and liquids. Eight‐year‐old schoolchildren and those presenting cavities in the primary dentition also showed higher prevalence of spontaneous dental pain. Conclusions. The prevalence and intensity of dental pain were considered high. The prevalence showed to be associated with female gender, higher age, the presence of cavities in the primary dentition and dental visit.     

MORBIDITY AND MORTALITY DUE TO AIDS: A STUDY OF BURDEN OF DISEASE AT A MUNICIPAL LEVEL

Introduction:

The purpose of measuring the burden of disease involves aggregating morbidity and mortality components into a single indicator, the disability-adjusted life year (DALY), to measure how much and how people live and suffer the impact of a disease.

Objective:

To estimate the global burden of disease due to AIDS in a municipality of southern Brazil.

Methods:

An ecological study was conducted in 2009 to examine the incidence and AIDS-related deaths among the population residing in the city of Tubarao, Santa Catarina State, Brazil. Data from the Mortality Information System in the National Health System was used to calculate the years of life lost (YLL) due to premature mortality. The calculation was based on the difference between a standardized life expectancy and age at death, with a discount rate of 3% per year. Data from the Information System for Notifiable Diseases were used to calculate the years lived with disability (YLD). The DALY was estimated by the sum of YLL and YLD. Indicator rates were estimated per 100,000 inhabitants, distributed by age and gender.

Results:

A total of 131 records were examined, and a 572.5 DALYs were estimated, which generated a rate of 593.1 DALYs/100,000 inhabitants. The rate among men amounted to 780.7 DALYs/100,000, whereas among women the rate was 417.1 DALYs/100,000. The most affected age groups were 30-44 years for men and 60-69 years for women.

Conclusion:

The burden of disease due to AIDS in the city of Tubarao was relatively high when considering the global trend. The mortality component accounted for more than 90% of the burden of disease.
