Abstract
245 patients their aged 16 years and above (mean 25.86, standard deviation 5.72 years: 55.51 % were females and 44.49 % males) were seen. They presented with 358 impacted mandibular third molars. (67.88 %) impaction were seen in patients between the ages of 16 to 25 years, while (89.67 %) impaction were seen between the ages of 16 to 30 years. Assessing the level of impaction using PELL and G R E G O RY classification showed that 154 (43.02 %) impaction were in position A, 135 (37.71 %) were in position B while 69 (19.27 %) were in position C. 89 of impacted teeth were in position I (24.86 %), 211 (58.94 %) were in position II, while 58 (16.20 %) were in position III. Between 358 impacted mandibular third molars, (62.29 %) had symptoms of pain. (67.6 %) impacted teeth were associated with pathological lesions. Out of these, 50.84% were periodontal disease and pericoronitis, 15.64% were caries, while 1.12 % were associated with cysts. In conclusion, the level of impaction suggests that a remarkable number of impacted mandibular third molars should be removed under general anesthesia. There is need for further studies to determine the levels of impaction, the types of anesthesia used during extraction and the outcome.
