Thus, visual dental stimuli provoke anxiety. This preliminary study aimed to assess the level of aversion to visual stimuli in dental patients and compare it with that in dentists.Patients and Methods: A total of 43 dental patients (25 women, 18 men; average age, 29.9 ± 13.3 years; patient group) and 13 dentists (4 women, 9 men; average age, 28.2 ± 2.0 years; dentist group) were included. All participants had previously undergone dental treatment. The dental fear level was assessed using the self-reported Dental Fear Survey (DFS). Thirty-two images associated with dental treatment were prepared and classified into three categories: dental instruments, dental procedures, and the dental environment. All participants rated their level of disgust toward each image on a visual analog scale with scores ranging from 0 to 100.Results: In the patient group, the disgust ratings for tooth extraction, dental drilling, and local anesthesia were > 60, which were significantly different from those in the dentist group (Mann–Whitney U-test, p< 0.001, p=0.001, and p=0.001, respectively). The ranking order of the disgust ratings for the 32 images showed significant correlation between the patient and dentist groups (Spearman correlation coefficient, r=0.80, p< 0.001). In the patient group, the disgust ratings for dental impressions and the interdental brush, dental light, and dental chair were significantly correlated with DFS scores (r=0.61, p< 0.001; r=0.47, p=0.001; r=0.41, p=0.006; and r=0.40, p=0.008, respectively).Conclusion: This study revealed that patients have more negative feelings toward invasive procedures than dentists. However, a significant correlation was identified between the ranking of aversion-provoking dental stimuli by patients and dentists. Furthermore, the level of aversion to several dental-related items that do not cause pain was correlated with the dental fear level.Keywords: dental anxiety, pain perception, visual stimuli, dental impression, visual analog scale
