Prevalence of Non-Carious Cervical Teeth Loss in a Sample of Erbil Population

Background and objective: Special emphasis is placed on the elevated occurrence of cervical non-carious tooth lesions across different age groups. The primary objective of this study is to assess the prevalence of non-carious tooth lesions in a sample of Erbil population. Methods: The study was done retrospectively from September 2022 to February 2023 at the Khanzad Teaching Center, Erbil, Iraq. Total of 270 patients who sought dental treatment rather than non-carious lesions and / or attended for routine checkup and then were selected randomly and categorized into five distinct age groups which start from 18 to over 58 years, Clinical examinations which consist of full mouth examination of the teeth by visual and Tactile to determine the presence of non-carious tooth. Result: The overall prevalence of non-carious tooth lesions was 34.2%, and this prevalence tended to rise with age, it has a significant role in developing tooth loss. Attrition shows a significant association with age (p<0.01), with a higher prevalence observed in older age groups. Attrition was observed in higher percentage than other defects (16.3%). the data reveals a higher prevalence of abrasion among males compared to females (6.00% vs. 2.80%, respectively). and females exhibit a slightly higher prevalence of abfraction compared to males (2.40% vs. 1.20%, respectively). Conclusion: The prevalence of non-carious cervical lesions exhibits a positive correlation with age, with a notable predilection for the vestibular tooth surfaces. Among these lesions, attrition emerges as the most observed non-carious tooth lesion.
