Abstract

BACKGROUND: The cause of mandibular third molar impaction is said to be due to inadequate space between the distal of the second mandibular molar and the anterior border of the ascending ramus of the mandible. The amount of space is determined primarily by facial growth. This study aimed to assess whether different patterns of facial growth lead to a different incidence of mandibular third molar impaction. It was hypothesized that those with predominantly horizontal (brachyfacial) would have lower incidence of mandibular third molar impaction compared with those with a predominantly vertical growth pattern (dolichofacial). METHODS: Ninety-eight dental records were sourced from the records of..
