Abstract

Background and objectives Dental anxiety (DA) and gagging (GAG) are prevalent problems that severely impact social behavior and quality of life. Furthermore, because dental phobia is considered a Blood-Injection-Injury (B-I-I) phobia, the present study contrasted DA, GAG and control subjects regarding the severity of dental anxiety and investigated the comorbidity of GAG, DA and B-I-I fears. Methods Demographics, Verbal Pain Scale (VPS), Oral Health Impact Profile-14 (OHIP-14), Decay, Missing and Filled Teeth (DMFT), Dental Anxiety Scale (DAS) and response to phobic stimuli were collected from 53 GAG, 68 DA and 80 control subjects. Results GAGs exhibited results between DA and controls regarding the likelihood to have high-anxiety/phobia (DA group: OR = 55.56; GAG group: OR = 17.24), self-assessed dental anxiety (OR = 29.14; OR = 17.48), fear of dental injections (OR = 8.51; OR = 2.91) and dental drills (OR = 12.02; OR = 5.82). DA and GAG had similar results regarding: DAS score (p = 0.13), fear of blood tests (OR = 4.68; OR = 4.09) and blood donations (OR = 3.13; OR = 3.10). Overlap between GAG, DA and a B-I-I fear was observed. GAG and DA patients and worse maximal VPS and OHIP-14 scores retained their significant positive association with the DAS score in the multivariate analysis. Conclusions The co-occurrence of DA, GAG and B-I-I-related fears suggests these entities are linked. However, different anxiety levels, symptoms and triggers, reflect the broad spectrum of fear of medical/dental situations.
