Mandibular third molar root migration after coronectomy was assessed. Roots migrated significantly, with younger age and female sex associated with greater migration.

Area of Science:

Oral Surgery
Dental Implantology
Periodontology

Background:

Coronectomy is a procedure to remove the crown of a mandibular third molar while leaving the root.
Understanding root migration is crucial for preventing complications like inferior alveolar nerve injury.

Purpose of the Study:

To evaluate early root migration following mandibular third molar coronectomy.
To identify factors influencing the extent of root migration.

Main Methods:

Prospective cohort study involving patients undergoing mandibular third molar coronectomy.
Root migration measured at 2 and 6 months post-surgery.
Factors analyzed included patient age, impaction pattern, and sex.

Main Results:

Keywords:

Coronectomy Mandibular third molar Root migration Third molars

Mean root migration was 3.30 mm at 2 months and 5.27 mm at 6 months.
Migration rates were similar between the 0-2 month and 2-6 month intervals.
Younger age and female sex were significantly associated with greater root migration.

Conclusions:

Root migration occurs following mandibular third molar coronectomy.
Migration is more pronounced in younger patients and females.
These findings aid in predicting and managing potential complications.
