[The effect of instrumentation on original apical foramen shape using steel vs niti rotatory: computerized analysis]
BACKGROUND. A fundamental requirement to obtain a correct endodontic preparation depends on the respect, during cleaning and shaping, of the original morphology of the apical foramen, (AF), so that the filling material will form a complete seal. METHODS. In our previous studies, in order to verify if this presumption was respected using rotary NiTi instruments with cutting tip, we instrumented extracted teeth characterised by a different degree of root curvatures. Using a standardized system to replace the sample, the original shape of the apical foramen of each tooth was recorded using a computerised technique and then compared to the shape after instrumentation. The data showed difference…
OSTEORADIONECROSIS OF THE JAW AFTER HEAD/NECK RADIOTHERAPY: CAUSES AND MANAGEMENT
Radiation therapy in combination with surgery and chemotherapy is the most common oncologic treatment for head and neck tumors. This combination of different therapies rappresents a successful treatment, however there are adverse side effects, the most severe and serious is the osteroradionecrosis (ORN). The primary treatment for ORN is to prevent its occurrence thus the best preventive procedure is to insert all patients in to a pre-cancer treatment dental protocol.
