This course discusses in detail some of the reasons for removal of the mandibular third molar, with or without symptoms or pathology.


Learning Objectives:

Upon completion of this course, participants should be able to do the following:

  1. List a differential diagnosis for lesions in the area of the mandibular third molar.
  2. Compile a good clinical history, radiological studies, and histological sampling to focus the differential diagnosis of lesions in the area of the mandibular third molar.
  3. Understand the potential for possible fatal consequences if close follow-up is not achieved.
  4. Enumerate the multiple treatment options for normal and pathologic variants of third molars and their associated lesions.
  5. Understand the continuing controversy surrounding third molars and their extraction.


The removal of the asymptomatic mandibular third molar is one of great debate and frequent controversy. Sometimes these teeth need to be removed early for signs or symptoms of pathology and sometimes they can be observed for further pathologic progression. This course details some of the reasons to remove third molars, with or without associated symptoms or pathology, and reviews surgical considerations involving third molars with associated pathology. The discussion includes developmental variations, impaction, anatomical abnormalities, caries, infections, cysts, and tumors, as well as complications of removal. A differential diagnosis is presented, with current treatment options and recommendations.
