چکیده

BACKGROUND AND AIM: Dental anomalies are typically detected in radiographic screening. The present study was conducted with the aim of investigating the dental anomalies found in panoramic radiographs taken from the study population in Ardabil, Iran, in ۲۰۱۵-۲۰۱۶.METHODS: The present study was conducted on ۱۸۰۰ panoramic radiographs obtained from ۷۹۹ men and ۱۰۰۱ women in the Radiology Department, Dental Faculty of Ardabil University of Medical Sciences, Ardabil. The radiographs were precisely evaluated in terms of various dental anomalies, including root dilaceration, missing teeth, impaction, retained deciduous, supernumerary teeth, peg lateral teeth, talon cusp, taurodontism, and lingual pit. The data were analyzed using the chi-square and Fisher’s exact tests.RESULTS: The results of this study revealed that ۳۳۱ patients had at least one dental anomaly. Dilaceration with ۴۲.۰% was the most common anomaly. The other anomalies detected in the radiographs included missing teeth, impaction, lingual pit, peg lateral teeth, retained deciduous teeth, supernumerary teeth, talon cusp, and taurodontism with a rate of ۲۰.۲%, ۱۸.۴%, ۱۰.۸%, ۱۰.۲%, ۷.۸%, ۶.۶%, ۱.۵%, and ۰.۳%, respectively. No cases of microdontia, macrodontia, germination, and fusion were observed. Dental anomalies were more incident among women than men (P = ۰.۰۱۰). Furthermore, the detected anomalies had a higher rate in maxilla compared to mandible (P = ۰.۰۱۰).CONCLUSION: As the findings of this study indicated, dilaceration was the most common dental anomaly, followed by missing teeth and impaction, respectively.
