Change From Baseline in Modified Gingival Index (MGI)
기간: 4, 12 and 24 weeks
|
Modified Gingival Index (MGI) (Lobene, Weatherford et al. 1986) was measured on six gingival areas of all scorable teeth, using a scale of 0-4 as follows: Scores Criteria 0 Normal (absence of inflammation)
Whole mouth MGI scores were calculated by summing all scores and dividing by the number of examined scorable sites. |
4, 12 and 24 weeks
|
|
Change From Baseline in Bleeding on Probing (BOP)
기간: 4, 12 and 24 weeks
|
Bleeding on probing was assessed 30 seconds after probing.
A dichotomous scoring system was used at six sites per tooth using one (1) and zero (0) for presence or absence, respectively.
BOP (%) is a percentage of sites BOP.
