CPITN indicates Community Periodontal Index of Treatment Need.
Means were obtained from analysis of variance (ANOVA) testing and compared by using Duncan's multiple range test (35). Different letters indicate groups are significantly different from one another at P <.05; if the same letter is present, the groups are not different from one another. Thus, a mean labeled (a,b) is not significantly different from one labeled (b,c) because they both have a "b" beside them. Higher oral quality of life scores represent poorer quality of life.
CPITN scores are as follows: <1, healthy periodontium; 1-1.9, gingival bleeding; 2-2.9, calculus; ≥3, moderate-deep periodontal pockets (need root planing).
