Objective To evaluate the levels of dental anxiety and its influencing factors in patients undergoing surgical procedures for tooth implants, and to explore the relationship between dental anxiety, state anxiety and trait anxiety. Methods One hundred and twenty-one patients were examined for preoperative anxiety level using modified Cora’s dental anxiety scale (MDAS), dental fear scale (DFS), state-trait anxiety inventory (STAI) before implantation surgery. And the Results were statistically analyzed. Results Prevalence rate of moderate or high dental anxiety (MDAS≥12) was 60.3%, and the mean MDAS score was (12.14±2.44). The differences of anxiety level between groups in gender, income level, self-rated oral health, being initial treatment or not, and if you have a dental implant surgery was statistically significant (P<0.05); the differences of marital status, education level and age was not statistically significant (P>0.05). There was a significant positive correlation between MDAS, DFS and S-AI score (P<0.01), and there was no correlation between T-AI and MDAS, DFS, S-AI score. Conclusion Dental anxiety in patients undergoing surgical procedures for tooth implants was extensive. The level of anxiety was affected by many factors, which was positively correlated with S-AI, and suggesting the necessity of preoperative anxiety intervention in clinical practice.
