“…Solubility parameter is expressed as ␦/MPa 1/2 [11,12]. Water is known to be used as an aging media in several studies [10,[13][14][15], ethanol and Methyl ethyl ketone (MEK) are known to represent food simulating solvents and cause an extreme dietary effect.…”

“…Entre as medidas mais importantes para se comparar materiais restauradores estão os valores de dureza em Vickers, uma propriedade mecânica que deve ser levada em consideração, especialmente, quando são confrontados com grandes áreas de esforço mastigatório 16,17 .…”

“…Possibly, polymers exposed to higher power density exhibited higher conversion 5,19 due to a combination of both photo and thermal effects. 5 The extent of conversion relates to the mechanical properties of a resin composite, 4,13,15,16,20 for example, the relationship between double bond conversion and final flexural strength has been explained by a linear model. 5 Therefore, possible increase in conversion in our setting may as well have lead to improvement of mechanical properties, and thus to increased shear bond strength.…”

“…10,14 The strong relationship between the extent of conversion and the mechanical properties of a resin composite is well-documented. 4,13,15,16,20 Therefore, it is hypothesised that bracket shear bond strength improves with increasing power density to a certain extent only. The objective of the present study is to test this hypothesis by investigating the relationship between shear bond strength and power density at a short exposure time.…”
