Overjet and periodontal health : a comparative study between senior and junior dental students

Abstract

The relationship between overjet and periodontal health was studied in 80 male dental students, 40 seniors and 40 juniors with age range from 19 to 24 years. The periodontal status was assessed by the Plaque Index, Gingival Index and probing pocket depth. A comparison of the periodontal health between the senior and the junior students was made. Chi-square test and one way analysis of variance were used for data analysis.The results indicated that there was a relationship between overjet and periodontal health as assessed by Plaque Index (in the upper and lower jaw for the senior students) and by Gingival Index (in the lower jaw for the junior students). However, no significant difference was found for pocket depth in both jaws and for the Gingival index in the upper jaw, for both senior and junior students.
