[Chronology and date of eruption of primary teeth in Senegal].

Chronology and eruption dates of primary teeth are parameters of importance in different medical scientific fields. We carried a longitudinal clinical study to determine these parameters in a local Senegalese population. The study interests a sample of 573 Senegalese Negro children of the two sexes and its aims are to situate these parameters formally and in space in on hand, and to be able to justify; in comparison to these parameters, the disturbances which accompany often the phenomenon of dental eruption in the other hand. We have results relating to chronology and eruption date of the 20 primary teeth of each of the children. Our study strengthens data already known but it reveals also other data as well as important. Other studies are however necessary to set a good board of chronology and eruption date of primary teeth in the Senegalese population.
