[The place of radiography in endodontic treatment carried out in general practice in Dakar].

An investigation conducted over dental surgeons of 52 dental offices in Dakar and it's near suburb (40 from private sector and 12 from public and quasi-public) has shown that the use of retro-alveolar radiography during endodontic treatment was not systematic, due to the price of retro-alveolar film, waste of time and relative facility of the endodontic treatment of monoradicular teeth. The preparatory negative is favored (32.70%) particularly by private dental surgeons, who use two retro-alveolar films for endodontic treatment: pre and post operative radiography (30%). The immediate post operator control is executed only in case of post-operator pains by public and quasi-public dental surgeons (16.67%) with one retro-alveolar film on average for the endodontic treatment; at term any radiographic control is done. Three retro-alveolar films per endodontic treatment were exceptionally used (9.61%) and offset incidences (15%) are not much used as well as support-films (angulators). The retro-alveolar radiography is still a reliable guide for a clinical success in endodontic treatment with a minimum of three retro-alveolar films and offset incidences.
