Measurements were made, using an acoustic transmission method, of the setting times of three visible-light curing sealants (two filled, one unfilled). Five commercially available visible-light polymerizing sources were tested with each material. Only three of the light sources gave setting times not significantly different from the manufacturers' recommended times for all three materials tested. The variation in microhardness with depth of sealant was measured to study the depth of polymerization of the sealants, all of which were adequate. The filled sealants had microhardness values greater than the unfilled sealant, at all depths studied.
采用声透射法对三种可见光固化封闭剂（两种含填料，一种不含填料）的凝固时间进行了测量。对每种材料测试了五种市售的可见光聚合光源。对于所测试的所有三种材料，只有三种光源给出的凝固时间与制造商推荐的时间没有显著差异。测量了封闭剂硬度随深度的变化，以研究封闭剂的聚合深度，所有封闭剂的聚合深度均足够。在所研究的所有深度下，含填料的封闭剂的硬度值均高于不含填料的封闭剂。
