Abstract: PURPOSE: To explore the occurrence of dental fear in patients undergoing impacted mandibular third molar extraction, and to provide evidence for formulating corresponding preventive measures. METHODS: Two hundred patients who underwent extraction of impacted mandibular third molar in outpatient operating room of Department of Oral and Maxillofacial Surgery of Shanghai Ninth People's Hospital,Shanghai Jiao Tong University School of Medicine from August 2021 to November 2021 were selected. A questionnaire survey was conducted with Dental Fear Questionnaire (DFS) to analyze ages, genders, occupations, education levels, and dental experience on the occurrence of dental fear and the related factors leading to dental fear. A total of 196 valid questionnaires were collected, and were randomly divided into routine treatment group and comfortable intervention group, with 98 cases in each group. Routine treatment and comfortable intervention were given corresponding management, and the satisfaction was compared between the two groups. SPSS 19.0 software package was used for data analysis. RESULTS: Among 196 cases, 35 cases(17.8%) developed dental fear, the average DFS score was 45.21±13.48. There was significant differences in the incidence of dental fear among gender, occupation and dental experience(P<0.05), no significant difference in age, education level and incidence of dental fear (P>0.05). The main factors causing dental fear in tooth extraction events were when the drill was grinding teeth(31.1%), when the sound of the drill was heard (29.6%), when the drill was seen (26.5%), and when anesthetic was injected (23.5%). The satisfaction of the comfortable intervention group was significantly higher than that of the routine treatment group(P<0.05). CONCLUSIONS: The occurrence of dental fear is affected by many factors. Targeted and comfortable intervention and nursing strategies can improve patients' satisfaction and have a positive effect on reducing patients' dental fear.
