Summary
This study found that impacted third molars are common in Saudi patients, occurring more often in the mandible. There was no significant difference in impaction rates between males and females.
Area of Science:
- Oral and Maxillofacial Surgery
- Dental Radiology
Background:
- Third molar impaction is a frequent dental anomaly.
- Understanding impaction patterns is crucial for diagnosis and treatment planning.
Purpose of the Study:
- To investigate the prevalence and characteristics of impacted third molars in a Saudi population.
- To analyze eruption levels and angulations of impacted teeth.
Main Methods:
- Retrospective analysis of 1039 orthopantomograms (OPGs) from patients aged 19-46.
- Evaluation of impacted third molar frequency, angulation, and eruption level.
- Statistical comparison between genders and jaw locations.
Main Results:
- A 40.5% prevalence of at least one impacted third molar was observed.
- Impacted molars were more common in the mandible (1.64 times).
- Mesial impaction was most frequent in the mandible (33.4%), vertical in the maxilla (49.6%).
Conclusions:
- High prevalence of third molar impaction in Western Saudi Arabia.
- Mandibular impaction is more prevalent than maxillary.
- No significant gender predilection for third molar impaction was found.
