The aim of this study is to retrospectively analyse the prevalence of diabetes mellitus and hypertension among patients undergoing dental implant treatment in a dental hospital. All the patients reported in the month of June 2019 to March 2020 for implant placement was chosen for the study. Implant placement data of patients with diabetes mellitus and hypertension was collected from the dental hospital record system. Result data was tabulated in excel and statistical analysis was done using Statistical Software for the Social Sciences (SPSS) software. The non parametric Chi square test was done for statistical analysis. The prevalence of diabetes mellitus in patients undergoing implant placement is 4.2%, hypertension is 2.2% and coexisting diabetes mellitus and hypertension is 1.7% with a higher ncidence in the male population and more common in the age group of 40 to 60 years. Knowledge about the prevalence of these conditions will be helpful to the clinician for proper management setup and precise diagnosis before implant therapy can prevent surgical and postoperative complications resulting in long term success of dental implants.
