Abstract: PURPOSE: To investigate the effect of continuous oral health education on patients with fixation after traumatic dislocation of teeth. METHODS: Sixty patients with fixation after traumatic dislocation of teeth from the Dental Emergency Department of Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine were randomly divided into control group and experimental group, thirty cases in each group. Patients in the control group were given clinical education at the time of treatments, while patients in the experimental group were given continuous oral health education after treatments. Pulp vitality, plaque index and oral hygiene behavior of the two groups were compared using SPSS 21.0 software package. RESULTS: The pulp activity of the experimental group was significantly higher than that of the control group 3 and 6 months after operation(P<0.05). The plaque index of the experimental group was significantly lower than that of the control group at 1st, 3rd, and 6th month after operation(P<0.05). The proportion of correct brushing, regular oral examination and good oral habits of the experimental group was significantly higher than those of the control group(P<0.05). CONCLUSIONS: Application of continuous oral health education in patients with fixation after traumatic dislocation of teeth can raise the living ratio of dental pulp, reduce plaque index and improve oral hygiene, which is worthy of clinical promotion and application.
