The purpose of this study were to determine the association of scores on the North Carolina Behavior Rating Scale (NCBRS) to those of the Frankl scale during restorative visits; and to quantify and compare rated behavior of children during an oral examination and restorative visits involving either a placebo or a combination of chloral hydrate (CH) and hydroxyzine. Fifteen patients 21-37 months old participated in this institutionally approved study. The study was a double-blind, crossover design. Following an examination using a mirror, explorer, and prophylaxis cup, the child received either a placebo or a combination of chloral hydrate and hydroxyzine.
The sequence was reversed at the next appointment. All exam and treatment visits were videotaped and analyzed using the NCBRS. In addition, all treatment visits were rated with the Frankl scale. The data were analyzed using a repeated ANOV A and correlation coefficients. The results showed a high interrater reliability(> 86% agreement) and a significant correlation between the NCBRS and Frankl scale (P < 0.001). No significant difference was found for the amount of disruptive behavior among oral examination, placebo, and medication visits (P :,; 0.097), although a consistent decrease in mean disruptive behavior for that order of visits was observed most frequently. The findings suggest the importance of rating behavior during a pretreatment visit before placebo or sedation visits. (Pediatr Dent 13:339-43, 1991)
