title: Prevalence of complications of simple tooth extractions and its comparison between a tertiary center and peripheral centers: a study conducted over 8,455 tooth extractions.
abstract: This study was conducted to investigate and compare the prevalence of complications of simple tooth extractions in a tertiary centre (BP Koirala Institute of Health Sciences, Dharan) and the peripheral centers (Mechi and Koshi zonal hospitals). This is a prospective descriptive study. Tooth extractions were carried out under local anesthesia in the tertiary and the peripheral centers during one year period (March 15"th 2004 to March H"111 2005). Intraoperative and postoperative complications were recorded and analyzed. Out of 8,455 tooth extractions in 6,639 [male-2,465 (37.12%) and females - 4,174 (62.88%)] patients aged between 5yrs- 65 yrs, 7,152 extractions were done in tertiary center and 1,393 extractions were done in peripheral centers.90 complications (1.06%) were observed. 53(58.89%) complications were intraoperative and 37(41.12%) complications were postoperative. 60(0.84%) complications were observed in the tertiary center and 30 (2.3%) complications were observed in the peripheral centers and the difference was highly significant (P<0.000001). The most frequent complication in the tertiary centre was fracture of tuberosity (0.15%) and in the peripheral centers it was 'roots left' (0.77%). Prevalence of 'roots left', injury to adjacent tooth and postoperative hemorrhage was significantly high (P<0.05) in peripheral centers. The higher prevalence rate of complications of tooth extractions in the peripheral centers should not be overlooked and well equipped and organized extraction procedure with qualified dental practitioner is strongly suggested to minimize the complications.
