Objective: The objective of this study is to determine the blood sugar level (BSL) in patient undergoing tooth extraction and evaluate rate of extraction socket healing in relation to BSL.

Methodology: 30 Patients with known history of Diabetes mellitus & need to undergo tooth extraction will be selected in this prospective observer blind study. Random blood sugar level will be checked preoperatively. All patients will undergo tooth extractions by standard method. Sutures will be placed to just approximate the mucoperiosteal flap. Socket healing will be evaluated using clinical criteria like pain, postoperative bleeding, postoperative infection, dry socket along with the socket width will be measured immediate postoperative and on 7th day postoperative. The difference will be evaluated in relation to preoperative BSL.

Result: The data was analyzed from 30 subjects. Out of which, 17 patients had BSL level less than 150mg/dl and 13 patients had greater than or equal to 150mg/dl and less than 300 mg/dl. The findings suggested that there is significant relation between the BSL levels of the patient and the socket healing based on all the criteria except infection.

Conclusion: Here we can easily say based on statistical analysis that all study parameters reject null hypothesis except infection. It means all parameters were significantly associated except infection. Also we can see in all study parameters, the percentage of pain, bleeding, socket healing, infection, and dry socket had more in greater than or equal to 150 and less than 300 BSL group as compared with less than 150 BSL in both the groups that immediately post–operative and after 7^th day.
