[Approach to pulpal and pulpo-periodontal lesions of the temporary teeth using therapeutic endodontics].

The anatomical and physiological properties of deciduous teeth make them susceptible to caries and inflammatory and infectious complications. This specificity, the proximity of the germ of the underlaying permanent tooth, and the relation of the last one to the deciduous tooth, make delicate its conservation by endodontal therapeutics after a pulpal or pulpo-periodontal affection. The success of this attempt is related to a good case-selection, based on the general condition of the child, his and his parents motivation, the condition of cariogenicity of the mouth, the analysis of the unity deciduous tooth/germ of the underlaying permanent tooth, the follow-up of the case. A success spares young children extraction of the deciduous teeth before the physiological period of permutation.
