- Primary Endpoint
- Presence of external root resorption (ERR) in mandibular 2nd molars in percentage
Study Overview
Brief Summary
The prevalence of external root resorption and distal caries in mandibular second molars associated with impacted mandibular third molars will be detected in addition to the association of the risk factors.
Detailed Description
Settings:
The data collection will be obtained from the data base available at the department of Oral and Maxillofacial Radiology, Faculty of Dentistry, Cairo University, Cairo, Egypt.
CBCT images will be obtained from Egyptian patients who had CBCT examination as part of their dental examination, diagnosis or treatment planning.
Variables:
- Angulation of the third molar according to Winter's classification (vertical/mesio-angular/disto-angular/horizontal).
- Position of impacted mandibular third molar according to Pell and Gregory21 classification. (Position A, position B, position C)
- Age.
- Gender.
