Third molar impaction: a review.
J Pak Dent Assoc Jan ;15(2):97-101.

Impaction is the failure of a tooth to erupt within due time due to obstruction by bone or adjacent tooth (teeth), overlying soft tissue, and lack of space which may occur due to tooth-jaw size discrepancy. Impaction most commonly occurs in third molars, more in mandibular than maxillary third molars followed by maxillary canines. Other teeth may become affected. However, as the third molar is the last tooth to develop and erupt in the oral cavity, it readily becomes impacted or displaced if there is insufficient space in dental arch. Third molar impaction should be treated as soon as it becomes apparent it will not properly erupt, and removed earlier to reduce morbidity and promote rapid healing. Nevertheless, many factors have to be considered while dealing with third molar impactions. The purpose of this review is mainly to provide basic information to general practitioners on the topic, so that they can recognize the condition early, manage wherever possible, and make appropriate referrals when indicated. This is a review article.
