Objective: To assess the association between the controlled and uncontrolled type-2 diabetic patients to the severity of Alveolar bone loss

Study Designed: Cross-sectional analytical study.

Place and Duration of Study: Department of Radiology, Sardar Begum Dental College and Khyber College of Dentistry Peshawar KPK from 1st October 2020 to 31st March 2021.

Methodology: One hundred and seventy patients were included. Daniel formula (1999) was used for the patient to check the alveolar bone loss and questionnaire was filled by the researcher and examination was done on the dental unit using examination instruments.

Results: The mean age was 39.41±6.92. The oral hygiene status in patients visiting the radiology department using toothpaste twice a day was 50.58% while bone loss among patient using toothpaste and brushing their teeth twice a day was 21.51%. The patient with a controlled glucose level was 41.28% while a patient with an uncontrolled glucose level was 58.72%. The bone loss in a patient with controlled HbA1c the bone loss in normal to moderate 38.38%while severe bone loss was 2.90% which is less as compared to the controlled group. The bone loss was reported higher in males (51.16%)as in females were 48.84%, but there was a severe bone loss in females 31,40% as compared to males 17.44%.

Conclusion: There is a strong association between alveolar bone loss with the increased level of HbA1c. When the levels of HbA1c level increased the bone loss in both male and female was reported high. Type 2 diabetic patients having increased HbA1c levels cause severe bone loss.
