Troisièmes molaires mandibulaires : Evaluation prospective des pratiques professionnelles lors de la prescription de Cone Beam Computed Tomography (CBCT) ,
Elle avait pour but l'évaluation des pratiques professionnelles lors de la prescription de CBCT pour l'examen des 3M avant avulsion, ainsi qu'une comparaison des rapports anatomiques observés sur l'orthopantomogramme (OPT) et sur le CBCT de ces mêmes cas. L'étude a inclus 39 patients correspondant à 56 3M Tous les CBCT étaient prescrits car il existait un rapport anatomique étroit entre NAI et 3M sur l'OPT : contact dans 28% des prescriptions et projection dans 72%. Lorsqu'il y avait présence d'un contact2% de ces cas présentaient un contact également sur le CBCT, dont seulement 33,3% d'entre eux avaient un NAI pincé. Lorsqu'il y avait présence d'une projection, 8% des cas présentaient un contact sur le CBCT dont 712% qui ne présentaient pas de contact sur le CBCT, la totalité de ces cas présentait un NAI en situation vestibulaire et non pincé ,
il y a une projection du NAI et de la 3M sur l'OPT. Concernant la radioprotection l'ensemble de ces examens semblent justifiés, cependant lors d'un contact, sa prescription ne semble pas impérative ,
