Aim: To compare the differences in the finger print patterns viz., total finger ridge count (TFRC), a-b ridge count and atd angle in patients with type II diabetes mellitus with non-diabetic as control group Materials and methods: The study is conducted in 75 type II diabetic patients and 75 non-diabetic persons as a control group. A sample of 51 male and 24 female patients suffering from type II diabetes mellitus in the age group of 30 to 60 years has been examined and compared with 75 normal persons (47 males and 28 females) in the same age group to know the difference in fingerprint patterns. We have also compared total finger ridge count, a-b ridge count and atd angle. For collection of palmar prints ‘Purvis Smith’ method has been used. Results: Increase in number of whorls, total finger ridge count, ab ridge count along with wider atd angle in type II diabetes mellitus patients. The result of the present study is more or less coincides with the observations of the earlier researchers. Conclusion: This inference may be widely applied clinically for the early diagnosis of type II diabetes mellitus mainly in a mass screening of a population as an additional diagnostic tool.
