Purpose: The purpose of this study was to determine how ethnicity influences parental acceptability of behavior management techniques (BMTs) used during dental treatment of children. This is the first known study to compare ethnic differences in acceptance levels of the BMTs. Methods: Parental acceptance of 10 BMTs (tell-show-do, voice control, non-verbal communication, positive reinforcement, distraction, parental presence/absence, nitrous oxide, protective stabilization, sedation, and general anesthesia) was rated using a visual analogue scale (VAS) after watching vignettes of each technique. Parental preferences were stratified by ethnicity and analyzed. Results: Among the 104 parents (21 Caucasians, 29 Hispanics, 30 Asians, and 24 African Americans) who qualified and completed the study, we observed that, overall, non-invasive techniques (positive reinforcement and tell-show-do) were most accepted by parents, while invasive techniques (voice control and protective stabilization) were least accepted (P<0.001). Within each ethnicity, there were significant differences between the BMTs (P<0.001). Additionally, conscious sedation was the only BMT to show a significant difference between the ethnic groups (P=0.047), with Asian parents having a lower mean score than Caucasian and Hispanic parents. Conclusions: Our results suggest that considering the ethnic/cultural differences of patients and their parents is an instrumental component for pediatric dentists to provide quality care to children patients.
