Convenient sampling technique was followed where all screened patients having TMDs included in the study. TMDs patients who have check-bite keratosis are 226 patients (60.6%). Female TMDs patients are the majority (75.60%) and 78.8% of TMDs patients with cheek bit keratosis were female. The highest numbers of TMDs patients (4.6%) were at age of 20 years old.
