摘要: We evaluated the influence of photoactivation method and hydrophobic resin (HR) application on marginal internal adaptation, hardness (KHN), crosslink density (CLD) a resin-based fissure sealant. Model fissures were created in bovine enamel fragments (n = 10) sealed using one following protocols: no adhesive system + sealant continuous light (CL), soft-start (SS), HR CL, or SS. Marginal gaps KHN assessed after storage water for 24 h. The CLD was indirectly by repeating measurement h immersion 100% ethanol. There difference among samples with regard to adaptation. similar cured either method. Use prior placement sealants curing may not provide any positive integrity density.
