Psychological, behavioral, and clinical effects of intra-oral camera: a randomized control trial on adults with gingivitis

Objectives To evaluate the effects of using an intra‐oral camera (IOC) during supportive periodontal therapy (SPT), on the psychological, behavioral, and clinical parameters of patients with gingivitis, outlined by evidence and a theory‐based framework. Methods A group of 78 adult patients with gingivitis receiving an SPT was randomized into two groups: IOC and control. Bleeding on Marginal Probing (BOMP), self‐reported dental hygiene behaviors, and psychological determinants of behavior change (outcome expectancies, self‐efficacy, and planning) and IOC opinion were evaluated 1 week before or during the appointment and 4 months later. Repeated‐measures anova was used to compare groups over time. Results Almost all the patients brushed their teeth daily, while 78% either never or hardly ever used dental floss. The IOC group showed significant improvements in BOMP index (P < 0.001), self‐reported flossing (P < 0.05), and self‐efficacy (P < 0.05) compared to the control group. Conclusions The use of IOC significantly improves clinical, behavioral, and psychological determinants of periodontal health 4 months after treatment.
