Course Description

The course introduces the students to basic knowledge and skill necessary to use plaque control measures on patients; educate and motivate them for maintaining oral Science. It teaches the students to identify and use of periodontal instruments for scaling, and maintenance of periodontal instruments, then refer the conditions which require specialized dental care.
