Abstract

Purpose: The purpose of this study was to determine the relationship of the CYP2B6 genotype to the clinical response to meperidine in pediatric dental patients. Methods: Forty-nine patients, ASA I/ II, 41–101 months old, received an oral sedative regimen containing meperidine for dental treatment. The North Carolina Behavior Rating Scale (NCBRS) and Overall Effectiveness of Sedation Scale (OESS) were used to assess their behavior and sedation outcome. Saliva DNA samples were genotyped by PCR-RFLP. Results: We found the following genotype distributions: homozygous wild-type 1*1 (n = 19, 39%), heterozygous 1*6 (n = 25, 51%), and homozygous variant 6*6 (n = 5, 10%). The genotypes showed a significant difference in the North Carolina Behavior Rating Scores and a trend towards significance of the Overall Effectiveness of Sedation Scale during meperidine oral sedations. Conclusion: This research concludes that variations of the CYP2B6 enzyme can be used in the prediction of successful behaviors for oral sedations that include meperidine in the drug regimen. Future research regarding the enzyme kinetics of meperidine is needed to determine the exact enzymatic function of CYP2B6 and its variants.
