OTSCC is the most occurring cancer diagnosed in the oral cavity worldwide. There has been a rise in the occurrence of carcinoma of the tongue, especially among non-alcohol and non-tobacco users. The aim of the study is to assess the prevalence of non tobacco tongue OSCC and to correlate with the dental factors. The retrospective analysis data was collected from the dental hospital management system records of Saveetha dental college in OSCC patients without any habits from June 2019 to March 2020. The Clinical details, history and dental factors were tabulated and analysed using statistical software SPSS. Fifteen cases of OTSCC were found to be not associated with any tobacco or alcohol habits. The most prevalent age was from 51 to 60 years and more common in males. The most common site was the lateral border of the tongue. 73% of the patients were not associated with any dental factor and the most common histopathological grade was WDSCC 66%. 60% of the patients had been diagnosed with stage III OTSCC. Within the limits of this study, there is a high prevalence of WDSCC in tongue OSCC in the lateral border of tongue in male between the age group of 51-60 years commonly in males. There was not much association seen with dental factors. The present study underlines the importance of in depth analysis of other etiological factors in OTSCC, thereby facilitating a better understanding of the biology and progression.
