The objective of this study was to evaluate the prevalence of non-carious lesions in South Canara population and factors responsible for the same. 2000 patients were evaluated using diagnostic instruments for the presence of attrition, abrasion, erosion and abfraction, followed by questionnaire, to evaluate most common factors associated with these lesions in South Canara population. Collected data were statistically analyzed using the “Statistical Package for the Social Sciences” (SPSSv16.0) software. The prevalence of attrition, abrasion, erosion and abfraction in South Canara Population was found to be 18.3 %, 27.9 %, 1.8 % and 5.2 %, respectively and it was more prevalent in 40-60 years of age group. Right handed patients had maximum prevalence of abrasive lesion on the left quadrants. Main aetiology for erosive lesions was found to be alcohol intake. It can be concluded from the present survey that; the age group that was most affected by non-carious lesion was between 40-60 years. There was no significant effect of gender on the prevalence rate of these lesions except for erosive lesions. (p-0.000) Also, no significant effect of location and diet was found on the prevalence rate except for the abrasive lesions (location, p-0.000 and diet, p-0.001).
