Ontario dentists: practice variation in referrals to pediatric dentists.

Variations in the pediatric referral practices of general dentists for children aged zero to 14 years may be related to issues concerning quality and standards of care, cost containment, and predictability in third-party payment programs. In September 1992, a survey mailed to a random sample of approximately 10 per cent of Ontario general dentists was used to gather information about pediatric referral practices as well as economic and demographic factors associated with these practices. Responses were received from 381 of the 540 dentists surveyed (69 per cent). Most dentists who gave reasons for pediatric referrals (85.6 per cent) named behavior management problems as the primary cause. However, 21.5 per cent did not refer any children under 14 to pediatric dentists. Due to the variable results obtained using assorted statistical tests to regrade the outcomes of interest, the self-reported nature of the data, and the large amount of pediatric referral practice variation left unexplained by the multivariate analysis (95 per cent), this study's findings are equivocal.
