Fig. 3From: Influence of light-curing distance on degree of conversion and cytotoxicity of etch-and-rinse and self-etch adhesivesDegree of conversion. Degree of conversion [%] (mean ± SD) of the different adhesives (OptiBond FL and OptiBond All-In-One) cured at different light-curing distances (1 mm, 4 mm and 7 mm). Within the same adhesive, values for different light-curing distances, that are not significantly different, are marked with same letters (lower case letters and capital letters for OptiBond FL and OptiBond All-In-One, respectively). Comparisons within the same light-curing distance between the different adhesives that are not significantly different, are marked with nsBack to article page
