Relative Frequency Of Biopsy Of Lesions In A Dental Hospital - A Retrospective Study

Introduction: Biopsy is a surgical procedure involving removal of whole tissue or lesion or removing a part of it for further investigation and diagnosis using histopathology features. The aim of this study is to assess the relative frequency of biopsy of lesions involving oral and maxillofacial regions in a dental hospital. Materials and Methods: Data from 86000 patients visiting Saveetha dental college during the time period of June 2019 to March 2020 were collected and reviewed. All relevant information like Age, Gender, type of biopsy, the diagnosis were extracted from the patient's records. The collected data is entered in Excel and processed using SPSS. Results: A total of 256 patients had undergone biopsy, 57.8% patients underwent Incisional biopsy 20.1% patients underwent resection and 21.5% patients underwent excisional biopsy. Majority of the patients affected are between the age of 41-50 years (22.7%) and most of them are males (68%). The most common diagnosis observed in our study is SCC. The results obtained are statistically significant (p<0.05). Conclusion: Majority of patients underwent incisional biopsy because most of the lesions are malignant. The most common diagnosis observed in our study is squamous cell carcinoma and this is probably due to habits like chewing tobacco, alcohol.
