Abstract

Objectives: Lower third molar surgery in undergraduate dental education is limited to selection of appropriate cases suited for their level of clinical experience to reduce the risk of complications. This study is aimed at identifying the operative details and post-operative outcomes in different types of third molar impaction among dental students. Methods: 50 cases of lower third molar surgery performed by undergraduate dental students were recruited and divided into Pell and Gregory, and Winter’s classification. Preoperative and postoperative facial measurements, neu- rosensory assessment, mouth opening, Oral Health Impact Profile-14 (OHIP 14), and postoperative complications were obtained. Results: There was no significant difference in the opera- tive time for different types of impaction in Pell and Gre- gory and Winter’s classifications with mean operative time of 83 minutes. Generally, the postoperative outcomes revealed significant increase in facial swelling, reduction in mouth opening, and increase in OHIP-14 score (p < 0.05). In comparing pre- and postoperative outcomes within Pell and Gregory classification, Class 1A showed significant increase in swelling postoperatively (364.3 mm vs. 376.0 mm) (p < 0.008) and significant reduction in mouth opening (47.7 mm vs. 41.3 mm). Significant reduc- tion in mouth opening was also reported in Class 2A (44.9 mm vs. 35.7 mm) and Class 2B (44.5 mm vs. 33.3 mm) (p < 0.05). In comparing within Winter’s classification, signif- icant reduction of mouth opening was observed in all types of Winter’s impaction (p < 0.05). No significant postopera- tive complications were reported. Conclusions: Different classes of Pell and Gregory and Winter’s classification of impaction did not strongly dictate the outcomes of third molar surgery. In general, no severe complications were observed in all surgical procedures done by undergraduate dental students under supervision when cases selected were limited to Pell and Gregory class 1A, 1B, 2A, 2B, and Winter’s classification of mesioangu- lar, vertical and horizontal.
