[The kinetics of apical cicatrization. An experimental study apropos of 25 cases with radiologic imaging].

The conventional usage of endo-canalar antiseptic of Rockle's type (SEPTODONT Laboratory) and the application of a standard protocol during two seances have shown: a 68% successful rate of healing at six months post therapeutic follow up, the diameter decrease of radiological images of peri-apical lesions, more than 80% in relative value; for about 20 teeth drawned lots (in a prospective study). This reduction of 33% at least at the maxillary and 50% at the mandible may be a reliable indicator for an endodontic surgical decision or fixed prosthetic rehabilitation report since the third month (especially peri-apical lesions of more than five millimetres of diameter). The respect of the security apical-limit of the root canal filling is fundamental. The second Senegalese (Dakar) serial will permit us to evaluate the use of calcium hydroxide in mediate and prolonged canalar disinfection.
