Design outcomes

Primary

MeasureTime frame
Gingival Index? Plaqe Index. Timepoint: Before starting the intervention in both groups? Two weeks after intervention in each group, two weeks after cleansing, two weeks after intervention. Method of measurement: For the gingival index variable, we first measured the four surfaces of the teeth with the help of a probe and if 0: normal gums, 1: mild inflammation, slight color change, no swelling, no BOP2: moderate inflammation, redness, swelling and glossiness of the gums with BOP3: severe inflammation with Redness and swelling, wounds and continuous bleeding, and for the index plaque variable from Fuchsin tablets, which is based on the amount of tooth surface color using the following formula (number of teeth)/(teeth 100 (percentage) x 4).
