Recognizing these grooves is crucial for identifying patients at higher risk for periodontal and endodontic issues, enabling more effective treatment in dental practices.&nbsp;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. </span><span style="line-height:200%"><span style="color:black"></span></span></span></span><br> <span style="line-height:200%"><span new="" roman="" times=""><b><span style="color:black">Materials and Methods:</span></b><span style="color:black">&nbsp;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.

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.</span><span style="line-height:200%"><span style="color:black"></span></span></span></span><br> <span style="line-height:200%"><span new="" roman="" times=""><b><span style="color:black">Conclusion:</span></b><span style="color:black">&nbsp;According to results, </span><span style="color:black">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.</span></span></span></span><span style="font-size:12pt"><span style="line-height:200%"><span new="" roman="" style="font-family:" times=""><span style="font-size:13.5pt"><span style="line-height:200%"><span style="color:black"></span></span></span></span></span></span><br> &nbsp; 15 21 http://cofs.khuisf.ac.ir/browse.php?a_code=A-10-1-59&slc_lang=en&sid=1 Amirreza Zefreh 1003194753284600798 1003194753284600798 No Faculty of Dentistry, Isf.c, Islamic Azad University, Isfahan, Iran Azadeh Torkzadeh 1003194753284600799 1003194753284600799 Yes Department of Oral & Maxillofacial Radiology, Faculty of Dentistry, Isf.c, Islamic Azad University, Isfahan, Iran Maryam Zare Jahromi 1003194753284600800 1003194753284600800 No Department of Endodontics, Faculty of Dentistry, Isf.c, Islamic Azad University, Isfahan, Iran Rojin Ardalani 1003194753284600801 1003194753284600801 No Department of Oral & Maxillofacial Radiology, Faculty of Dentistry, Isf.c, Islamic Azad University, Isfahan, Iran
