Parents' willingness to pay (WTP) is measured for three different services provided in a community hospital dental clinic and a school-based(More)

BACKGROUND Probiotic supplementation can reduce mutans streptococci (MS) numbers. One of its proposed mechanisms is immunomodulation. Salivary human neutrophil peptide 1-3 (HNP1-3) levels have previously been demonstrated to be higher in caries-free than in caries-susceptible children, suggesting their preventive role against caries. We aimed to compare(More)
OBJECTIVES To identify the optimal levels and mix of basic dental services (sealants and fillings for permanent teeth and extraction of primary teeth) under two different dental settings: hospital-based and mobile dental clinics under specified resource constraints. METHODS A linear programming model is used based on explicit identification of system(More)
OBJECTIVES To assess the transition process of sealant retention and to determine the effect of sealant loss on subsequent caries.
