Evaluation of various feedback mechanisms in relation to compliance by adult patients with oral home care instructions.
The purpose of the present study was to examine the effect on oral hygiene and gingival health of plaque scoring and the performance of a 'tooth brushing test" at each visit during initial periodontal treatment. A total of 63 adult periodontal patients (22-67 years of age) was allocated to 4 matched groups: Brushing test group (B), open scoring group (O), minimal feedback group (M) and control group (C). The oral hygiene instruction for groups B, O and M was provided by handing out a self-educational manual on oral home care, while the patients of control group (C) received a short brochure describing the Bass brushing technique and the use of toothpicks. Feedback on the improvement of oral hygiene performance was delivered to groups B and O by scoring of plaque and gingival bleeding by probing while this feedback was avoided in the 2 other groups (M, C). The patients of group B performed a tooth brushing test at each of 3 visits. After 3 months the plaque scores of groups B (27%) and O (22%) had improved more than those of the 2 other groups (35%). However, the improvement in gingival bleeding scores was similar in all 4 groups (from 55% initially to 17% at 3 months). At later examinations only minor differences in plaque and gingival bleeding scores were recorded between the various groups. The findings show that, irrespective of the mode of instruction, a considerable improvement occurs and that this improvement is not related to open scoring of plaque or the tooth brushing test.
