Summary

Routine removal of unerupted third molars is justified, especially for patients over 20. Pathologic conditions in pericoronal tissue were found in over half of the examined unerupted third molars.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Dental Pathology
  • Histopathology

Background:

  • Unerupted third molars can develop pathologic conditions in their surrounding pericoronal tissue.
  • The necessity of routine removal is often debated based on the incidence of these conditions.

Purpose of the Study:

  • To determine the incidence of pathologic conditions affecting the pericoronal tissue of unerupted third molars.
  • To assess if these findings justify the routine removal of these teeth.

Main Methods:

  • Histologic examination of pericoronal tissue from 104 surgically removed unerupted third molars.
  • Analysis of tissue from patients aged 13 to 63, including both mandibular and maxillary third molars.

Main Results:

Related Experiment Videos

  • Pathologic tissue was found in 58.65% of cases, compared to 41.35% normal dental follicle tissue.
  • Pathologic conditions included dentigerous cysts (50.96%), chronic inflammatory tissue, odontogenic keratocysts, and ameloblastomas.
  • Pathologic incidence increased with age, being higher than normal tissue in patients over 20 years old.

Conclusions:

  • The high incidence of pathology in unerupted third molars supports their prophylactic removal.
  • Routine removal of unerupted third molars is recommended, particularly for individuals older than 20 years, to prevent pathologic changes.
