[Application of a segmentation method to an intraoral epidemiologic survey]

The segmentation method has been applied to the results of an epidemiological study on the oral conditions of 2000 children of Strasbourg, 6 to 15 years old. The classification in decreasing order of the factors influencing the DMF/T index was the following: the age, the socio-professional group of the father, the sex, the calculus index, the gingival index, the df/t, the morphological index and the plaque index. The df/t index was bound in decreasing order of importance to the DMF/T index, the age, the socio-professional group of the father, the sex, the calculus index, the gingival index, the plaque index and the morphological index. For the gingival index, the segmentation analysis indicated in decreasing order the importance of the plaque index, the socio-professional group of the father, the age, the DMF/T index, the calculus index, the df/t index, the morphological index and the sex.
