Abstract:   (206 Views)
Background: Palatal root grooves are developmental anomalies often found in maxillary incisors, originating around the cingulum and potentially extending along the root. Recognizing these grooves is crucial for identifying patients at higher risk for periodontal and endodontic issues, enabling more effective treatment in dental practices. This study aimed to assess the prevalence of palatal grooves in the lateral maxillary teeth among patients referred to the Radiology Department at Azad University in Isfahan, using CBCT, due to limited existing research in Iran.
Materials and Methods: This descriptive-analytical cross-sectional study examined 150 CBCT images of 300 lateral maxillary teeth. The scans were obtained from the anterior maxillary teeth of patients referred to the Radiology Department of Isfahan Azad Dental School within the age range of 11 to 60 years from October 2023 to August 2024. Available scans were analyzed in axial and sagittal views. The data were recorded and analyzed using an independent t-test (α = 0.05).
Results: The prevalence of palatal grooves in the lateral maxillary teeth was 18.7%. Of these, 71.4% were unilateral, and 28.6% were bilateral. 85.7%of grooves were Type I, and 7.1% showed Type II and III.
Conclusion: According to results, palatal root grooves, primarily unilateral and classified as Type I, are common anomalies in maxillary lateral incisors, occurring in 18.7% of the studied Iranian population. Their prevalence emphasizes the need for thorough clinical and radiographic evaluations to reduce risks of periodontal and endodontic complications. Cone-beam computed tomography (CBCT) is recommended for accurate detection and treatment planning.
