Background: Impacted tooth is a tooth which is completely or partially unerupted and is positioned against another tooth, bone or soft tissue so that its further eruption is unlikely, described according to its anatomic position. The present study was conducted with the aim of analysing the third molar impaction in facial types and mandibular length. Materials & methods: 200 patients were enrolled in the present study. Clinical measurement was done for evaluating Facial height, and Facial width. Cephalometric measurements were done using scale and protractor. Mandibular length was assessed. Facial index was calculated based on method described by Martin and Saller in 1957. After calculation, facial indexing was divided into following types: Brachyfacial (broad face) and Dolicofacial (long face). All the results were recorded in Microsoft excel sheet and were analysed. Results: Short mandibular length was seen in 40.5 percent of the patients while normal length was seen in 59.5 percent of the patients. Significant association was seen between mandibular length and impaction. Dolico-facial facial index was seen in 53 percent of the patients. However; result was found to be non-significant. Conclusion: Dolicofacial pattern had enhanced percentage of impaction. However; significant results are still lacking and require further evaluation.
