Objective To reveal the oral hygiene status of adolescents with invisible appliances, identify the importance of individual health education, and provide a theoretical basis for clinical practice. Methods Sixty adolescent patients with invisible appliances were divided into two groups according to health education mode. Twenty adolescents without any orthodontic treatment were enrolled to the blank group. Plaque index (PLI) and bleeding index (BI) were used to describe the status of oral hygiene before, 1 month after, and 6 months after treatment. Results Before treatment, the highest PLI was recorded in the right maxillary first molar of all groups, and the lowest PLI was observed in the left maxillary central incisor. After treatment, the PLI of the experimental group significantly decreased while that of the control group showed no significant change. The BI in the experimental group did not change, but an increase in this index was observed in the control group. Both PLI and BI tended to decrease in the blank group. At the same check-points, statistical differences in terms of PLI and BI were observed between the experimental and control or blank groups.Conclusion Intensified individual oral health education can improve the oral hygiene status of adolescents with invisible appliances.
