[The impact of socioeconomic status in the estimation of non-adult dental age].
The aim of this study is to observe the possible impact of socioeconomic level on stages of macroscopic dental development. The sample consists of 456 children from European origin, aged 3.5 to 16 years (242 girls and 214 boys). We apply a radiographic method of non-adult dental age estimation based on Bayes' theorem. Both socioeconomic level and geographic origin of grandparents are given in a questionnaire devised by the first author. First, results obtained with the Bayesian dependent method (BD method) are compared to those obtained with a more commonly used method of dental age estimation based on Correspondence Analysis and linear Regression (CAR method). Second, two approaches are proposed in order to test potential relationships between socioeconomic level and stages of macroscopic dental development. Both are based on observed shifts between dental age and chronological age with regard to socioeconomic level. Results obtained with the BD method are better, in terms of quality, than those obtained with the CAR method. We observed no influence of socioeconomic level on stages of macroscopic dental development.
