PREVALENCE OF NON-CARIOUS TOOTH WEAR IN PATIENTS REPORTING AT ABBOTTABAD INTERNATIONAL DENTAL HOSPITAL
Non-carious tooth wear lesions are associated with a number of dental complaints including sensitivity, esthetic complications, poor oral hygiene (plaque accumulation) and tooth fracture etc. Cervical area is one of the commonest site where such type of lesions can be present. There is no data that is available regarding prevalence of such lesions in our population. The objective of this study was to find the prevalence of non-carious tooth wear lesions in patients reporting at Abbottabad International Dental Hospital. The study was conducted over a period of six months on patients reporting at Dental OPD of Abbottabad International Dental Hospital. This study which is descriptive in nature was conducted after formal approval of Ethical Review Board of Abbottabad International Medical & Dental College. Irrespective of the gender 344 patients between age 20 to 60 years were examined using Smith and Knight tooth wear index (TWI). Five surfaces i.e. Cervical (C), Buccal (B), Occlusal / Incisal (O & I), Lingual (L) of every tooth in both the maxillary and mandibular arch were examined. It was found that the prevalence of non-carious tooth wear is likely in molars followed by premolars and least evident in incisors. O&I surfaces were more prone to damage followed by the cervical surfaces. Lingual surfaces are least prone for non-carious tooth wear. Descriptive statistics, mean, median, and standard deviation were applied to the data to conclude the prevalence outcomes of non-carious tooth wear. Molars and premolars were the most affected teeth with non-carious tooth wear and incisors were least affected teeth. O&I surfaces were more affected followed by the cervical surface with least occurrence of these lesions on lingual surface.
