Abstract
Objective:
to suggest a composite indicator that identifies the oral health condition of institutionalized elderly persons.
Method:
an observational and cross-sectional study was performed. A total of 315 elderly persons were investigated in long-stay care facilities for the elderly in the city of Natal, Rio Grande do Norte, Brazil. Such individuals underwent an epidemiological evaluation of their oral health conditions, based on the DMFT index, CPI and the PAL (periodontal attachment loss) index. Factor analysis was used to identify a relatively small number of common factors by principal component analysis.
Results:
five oral health variables were included in factor analysis, and using the Kaiser criterion, which considers the percentage of variance explained by the factors, a single factor which together explained 79.7% of the total variance of the variables included in the analysis model was selected. This factor was analyzed and interpreted according to the dimension to which it related, and was entitled the factor of Dental Functionality.
Conclusion:
this factor generated an objective indicator to characterize the oral health of the elderly in long-term care facilities for the elderly of Natal, Rio Grande do Norte, and represents a parameter for studies of the oral health outcomes of this elderly population. It also revealed a change in the dental profile of this population with more teeth present in the mouth and a reduction in edentulism.
