Background: World Health Organization (WHO) documented Diabetes Mellitus (DM) as the seventh most common chronic disease in the world. In Saudi Arabia, 23.9% of the population has DM. Many studies showed that diabetic patients have higher rate of alveolar bone loss and missing teeth comparing to non – diabetic patients. Kennedy’s classification is commonly used to describe the distribution of edentulous areas in the arch. According to Kennedy’s classification, the suitable prosthetic option will be selected and designed to replace missing tooth/teeth. Objective: To compare the frequency patterns of partial edentulism among diabetic and non-diabetic patients according to Kennedy's classification at KAMC-Jeddah. Methodology: This study performed at the dental department of KAMC. 502 patients were selected randomly. The diabetic and non – diabetic patients were 248 and 254, respectively. All patients were classified according to Kennedy’s classification using panoramic radiograph and medical records. The data were collected and analyzed used SAS version 9.4 and Fisher Exact test. Result: Kennedy’s Cl III was the most prevalent in non-diabetic patients and in the upper jaw for diabetic patients, while Cl I was the most common in diabetic lower jaws. Kennedy's Cl IV was the least prevalent in diabetic and non- diabetic patients for maxilla and mandible. Conclusion: The distribution of Kennedy’s classification among diabetic and non-diabetic patients was significant.
