Background. There is little information regarding the ability of observational scales to properly assess children’s behavior during procedural sedation. Aim. To evaluate the characteristics of the Houpt scales, the Ohio State University Behavioral Rating Scale (OSUBRS) and the Venham Behavior Rating Scale when applied to preschool children undergoing conscious dental sedation. Design. This study included 27 children, 4–6 years old with early childhood caries that participated in a clinical trial (NCT02284204) that investigated two sedative regimes using oral midazolam/ketamine. Dental appointments were video-recorded; five calibrated observers assessed 1,209 minutes of video recording to score the children’s behavior, following the instructions of the investigated scales. Data were analyzed by descriptive analysis and Spearman correlation tests (P<0.05). Results. The Houpt overall behavior and the Venham scale were highly correlated (rho = −0.87; P<0.001). OSUBRS scores were better correlated with Houpt overall behavior and Venham ratings, when compared to Houpt scores in the categories for movement and crying. Conclusions. The Houpt overall behavior and the Venham scores are global scales that properly measure children’s behavior during dental sedation. Continuous assessment with OSUBRS through videos has a chance to give more precise data, while the Houpt categories can easily demonstrate children’s behavior during procedures.
