Non-syndromal supernumerary teeth (NSST) were found in 1.2% of patients. Pre-molars were the most common type of NSST, and consanguinity may play a role in hyperdontia development in the Saudi population.
Area of Science:
- Dentistry
- Oral and Maxillofacial Surgery
- Human Genetics
Background:
- Non-syndromal supernumerary teeth (NSST) represent a dental anomaly.
- Understanding the prevalence and distribution of NSST is crucial for diagnosis and treatment planning.
Purpose of the Study:
- To describe the distribution of non-syndromal supernumerary teeth (NSST) in patients attending Riyadh Colleges of Dentistry and Pharmacy (RCsDP).
Main Methods:
- Retrospective review of 1521 panoramic radiographs from Saudi and non-Saudi subjects.
- Data analysis using SPSS with Chi-square tests.
Main Results:
- Eighteen patients (1.2%) presented with NSST.
- Pre-molars were the most frequent type (33.3%), followed by mesiodens (27.8%).
- Consanguinity was observed in 72.2% of cases with NSST.
Conclusions:
- Consanguinity may be a contributing factor to hyperdontia in the Saudi population.
- Further research is needed to elucidate the genetic and environmental factors influencing NSST development.

The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
