Paediatric dentists' stress during dental care for children under sedation: a cross-sectional study.

Abstract

The knowledge of the stress related to the practice of paediatric dentistry is scarce. The aim of this study was to verify the stress perceived by paediatric dentists related to young children's dental treatment under sedation and their association with child's behaviour and other independent variables. A cross-sectional repeated measures study was performed with four paediatric dentists who treated 81 sedated preschoolers. Paediatric dentists reported their stress at the end of the session using the visual analog scale (VAS 0-100mm). Samples of saliva were collected to measure the dentists' salivary cortisol level throughout the dental session. The sessions of dental treatment were video recorded for evaluation of the child's behaviour. Children's behaviour was assessed using the Ohio State University Behavioral Rating Scale (OSUBRS). The association between the VAS scores and the other variables was verified using bivariate tests and generalised estimating equation (alpha 0.05). Paediatric dentists felt slightly stressed in most of the sessions (VAS median 7 points; minimum 0, maximum 97 points). VAS associated with the struggling behaviour of the child (B 0.53; 95%CI 0.32-0.74; p ≤ 0.001) and the time since dentist's graduation (B -1.41, 95% CI -1.87 to -0.94; p ≤ 0.001) but not with dentist's salivary cortisol (rho -0.053, p = 0.639). The more frequent the child's struggling behaviour during dental treatment and the shorter the time elapsed since the professional's graduation, the higher the level of objectively and subjectively measured stress of the paediatric dentist during the dental procedure.
