["Tooth mortality" in a Marseille S.C.T.D. The effect of periodontal disease: comparison with some results of a national epidemiological study]. / Etude descriptive de la "mortalité dentaire" dans un S.C.T.D. Marseillais. Impacts de la maladie parodontale; confrontation avec certains résultats d'une étude épidémiologique nationale.

1,247 avulsions have been noted for a year in the S.C.T.D. (tooth, age and sex of the patient). 44.6% were caused by tooth decay. However periodontal disease was responsible for 39.5% of tooth avulsions. The tooth lost because of periodontal disease were in most part extracted after 40 years. A weakness of some type of teeth regarding tooth mortality may be quoted. A sexual dimorphism of tooth mortality was present in the studied population.
