Estimated Impact of Competing Policy Recommendations for Age of First Dental Visit

Abstract

To compare levels of dental utilization and untreated dental decay among children aged 1 to 3 years that are likely to occur under 2 potential guidance policies: (1) pediatricians refer all toddlers to dentists for screening (consistent with American Academy of Pediatric Dentistry and the American Dental Association recommendations; DENT), and (2) pediatricians receive training in caries risk assessment, screen toddlers, and refer at-risk children to dentists (consistent with American Academy of Pediatrics recommendations; PED). Using decision analysis, we estimated the impact of PED and DENT assuming alternately unlimited dental capacity for Medicaid-insured patients and fixed Medicaid dental capacity. Results With unlimited capacity, if DENT were implemented, then dental utilization is estimated to increase from 27% under the status quo to 65% and untreated decay to decrease from a mean of 0.60 surfaces to 0.52 surfaces per child. If PED were implemented, then dental utilization and untreated decay would decrease from status quo levels to an estimated 11% and 0.47 surfaces, respectively, assuming that diagnostic sensitivity and specificity both equaled 1; they would decrease to 13% and 0.53 surfaces, respectively, if sensitivity equaled 0.76 and specificity equaled 0.95. With fixed capacity, under DENT, untreated decay is estimated to increase to 0.63 surfaces because low-risk private-pay patients would crowd out at-risk Medicaid-insured children, whereas under PED, untreated decay would still be less than under the status quo. Implementing PED will decrease untreated decay under most plausible scenarios, whereas switching to DENT will increase the burden of disease if Medicaid dental capacity is limited.
