Non-carious loss of tooth structure is considered the 4th dimension risk factor for

aesthetic, function and longevity of human dentition after acute trauma, caries and

periodontal disease The aim of this study was to determine the prevalence and risk

indicators for tooth wear in (18- 25) years in Sulaimani city. A total of 500 randomly

selected college students were examined for tooth wear. The data were collected by means

of a questionnaire about the history of possible causative factors and a clinical

examination using Smith and Knight’s index on occlusal/incisal, buccal and lingual/palatal

surfaces. Mild tooth wear (score 1) was present in 63.4%, while only 0.4% had lesions

extending up to the dentine. There were 36.2% without tooth wear, there is no evidence of

score 3 or score 4. Incisal edges of both lower and upper teeth were the most affected site

(75.51%). Occlusal problem was the most common predisposing factor (72.73%). Tooth

wear defect did not form an urgent problem at 18-25 years aged group, there was only

minimal enamel loss (63.4%, score 1) that attributed mainly to occlusal problems.
