Graph 1.

The above graph represents the correlation between the type of teeth (anterior and posterior) with the mean of the average contact angle estimated on individual teeth surfaces. The mean of the contact angles of the anterior (88.41°, blue) and posterior tooth (80.35°, red) was found. The mean of the contact angles of the anterior teeth is greater in comparison with the posterior tooth. The anterior teeth have less wettability when compared to the posterior teeth as contact angle is inversely proportional to wettability
