The relationship between satisfaction with mouth and number, position and condition of teeth: studies in Brazilian adults.

The objective of this study was to analyse adults' subjective perception of satisfaction in relation to number, position and condition of natural teeth. Subjective perception of satisfaction was assessed by interview. Dental status was assessed. Two types of survey were carried out in Brazil: a longitudinal and a cross-sectional survey. The longitudinal study commenced in 1990, with 227 dentate people aged 45-54 years, of two social classes. Of the 227 subjects examined in 1990, 126 were re-examined and interviewed 3 years later. The cross-sectional survey used the same methods used for the longitudinal study. Six hundred and fifty-seven dentate males aged from 35 to 54 years were examined and interviewed. There was a positive correlation between satisfaction and position of teeth. Premolar pairs had a higher correlation with satisfaction in both studies. Anterior teeth were the most significant predictors of satisfaction. There was no difference in the percentage of satisfied persons between the baseline and follow-up studies. The results indicate that adults with three premolar pairs and intact anterior sextants were satisfied with their oral status. Keeping a certain number of teeth, depending on their position and condition, gave more satisfaction than having the missing teeth replaced with partial dentures.
