Summary
The prevalence of congenitally missing mandibular second premolars is 0.7% in the Palestinian population. This finding aligns with global prevalence rates for this dental anomaly.
Area of Science:
- Dentistry
- Oral Health
- Human Anatomy
Background:
- Congenitally missing teeth are a common dental anomaly.
- Mandibular second premolars are among the teeth frequently affected by agenesis.
- Understanding prevalence is crucial for diagnosis and treatment planning.
Purpose of the Study:
- To determine the prevalence of congenitally missing mandibular second premolars in a Palestinian population.
- To analyze demographic associations with this dental anomaly.
Main Methods:
- Retrospective study design.
- Analysis of 1,843 panoramic radiographs from five Palestinian cities.
- Independent examination by two experienced dentists.
Main Results:
- A prevalence of 0.7% for congenitally missing mandibular second premolars was observed.
- No significant association found between gender and agenesis.
- Unilateral agenesis was more frequent than bilateral.
- The left side showed a higher incidence than the right side.
Conclusions:
- The prevalence of congenitally missing mandibular second premolars in Palestine is 0.7%.
- This prevalence falls within the range reported in other populations worldwide.
- Findings contribute to the global understanding of dental agenesis patterns.
