【摘要】Objective To evaluate clinical effects of determining root and opening (apical tip of the narrow root canal) diameters for selection of wider master gutta-percha points on root canal filing. Methods 120 patients from our department treated for either pulpitis or apical periodontitis were selected. The conventional procedures such as opening dental pulp cavity and determine the working length of the root canal were performed.Patients were divided into two groups (experimental and control) by 60 cases each. Experimental group: The root end opening (apical tip of the narrow root canal) diameters was measured and determined. Conventional root canal preparation and disinfection were performed. Master gutta-percha that was wider than the apical base tip diameter was selected and root canal sealer was applied by lateral pressure filing. Control group: Conventional root canal preparation and disinfection were performed. Master gutta-percha that was matched with root canal length was selected and root canal sealer was applied by lateral pressure filing. Results Experimental group: 3 cases less filed by 2 mm and 57 cases normal filed. Al were painless.
