Success rate of apicectomy of anterior and premolar teeth

Abstract

This study was carried out to assess the success rate ofapicectomy of anterior and premolar teeth. Out of 336 patients,who had undergone apicectomy in a private practice between1997–2001, only 256 patients (76.2%) completed the twoyears recall visits; which was the minimum time recommendedin this study to judge whether the operation was successfulor not. The age range of the patients was 12–67 years(mean of 34.7 years), 136 were males and 120 were females.The overall success rate of apicectomy in this study was89.1%. Sex of the patient had no bearing on the success rate(p > 0.05). Highly significant influence of the patient’s age onthe success rate was observed (p < 0.01); the success rate increasedproportionally with increased age. Highly significantinfluence of the type of the apicectomised tooth on the successrate was noted (p < 0.001); upper anterior teeth showed thehighest success rate (92.1%), whereas upper premolars showedthe lowest success rate (77.4%). Periapical condition of thetooth prior to the operation, preoperative vs postoperative obturationof the root canal, and orthograde obturation vs retrogradeobturation were not significant factors affecting the successrate of apicectomy (p > 0.05).
