Abstract: This study was undertaken on 14 teeth in order to evaluate a new technique for radiation dose reduction during endodontic therapy. After examination of the preoperative film, usually available in the patient file, an apex locator (Root ZX) was used to measure the working length. Complete chemomechanical debridement was then performed, and the master cone was evaluated by a digital imaging system (RadioVisioGraphy (RVG)). Obturation was performed when measurements of the electronic device and RVG were comparable. A postoperative image was made by the RVG system to evaluate the final obturation. A clinical and radiographic follow-up examination (follow-up period: 6 to 8 months) revealed satisfactory apical healing. These results indicated that a successful obturation technique can be performed by a single radiation exposure, using the RVG unit for master cone evaluation. This technique may be useful in medically compromised patients who need not to be exposed to excessive or repeated radiation during endodontic therapy.
