Objectives: The aim of this study was to evaluate and compare the clinical retention rate between hydrophilic and hydrophobic resin-based sealant placed under field setting and related factors.
Materials And Methods: Sixty-six children with 106 pairs of teeth in the same arch with matching International Caries Detection and Assessment System (ICDAS) scores ranging from 0 to 2 were recruited. This study was a split-mouth design with each tooth in the pair randomly assigned into either hydrophobic resin-based sealant group (Concise white sealant, 3M.
