This study, conducted from a government program perspective, compared the incremental cost-effectiveness of oral health interventions, in particular their delivery to underserved populations in whom dental sealants constitute an important, high-yielding complement to toothbrushing in dental-caries prevention. The study data concern the relative cost-effectiveness of three sealant materials in four approaches to prevent cavitated dentine carious lesions in permanent molars in a community intervention trial among school-age children in Wuhan, China. The four approaches were high-viscosity glass-ionomer cement without heat application (HVGIC); high-viscosity glass-ionomer cement with heat application [light-emitting diode (LED) thermocured HVGIC]; glass-carbomer; and composite resin. The costs studied were: cost of sealing permanent molars; adverse event costs for restoring cavitated dentine carious lesions developing within 4 yr in study data; and projections of 1,000 sealants per group. Preventing one more cavitated dentine carious lesion cost US$105 for the study data when comparing HVGIC (n = 405) with composite resin (n = 396) and US$59 per 1,000 sealants in the projections; LED thermocured HVGIC compared with composite resin cost US$115 for one more cavitated lesion and US$52 per 1,000 sealants, respectively. Although more expensive than composite resin, LED thermocured HVGIC was identified as the most cost-effective among the sealant materials studied. Ease of application, minimal technical and infrastructure requirements, and cost-effectiveness make glass-ionomers a practicable option for governments making decisions under economic constraints.
