Effects of QCC on improving the compliance of tooth brushing in adolescent patients with orthodontic treatment of fixed appliance

Objective To explore the methodology and effects of quality control circle (QCC) on improving the compliance of tooth brushing in adolescent patients with orthodontic treatment of fixed appliance. Methods A QCC activity conducted from February to August in 2014, focused on improving the compliance of tooth brushing in adolescent patients with orthodontic treatment of fixed appliance. The study investigated 90 participants and compared their compliance of tooth brushing, plaque index (PLI) and gingival index (GI) before and after QCC. Results After the activity, the score of tooth brushing compliance was (10.68±2.78), PLI (1.29±0.41) and GI (0.86±0.37). All the assessment indexes and the comprehensive quality were significantly improved after QCC (P<0.05). Conclusions QCC is efficient to promote the compliance of tooth brushing and oral hygiene, and to improve the comprehensive ability of adolescent patients with orthodontic treatment of fixed appliance.
