| Summary: | <span style="font-family: TribuneItalic; font-size: 9pt; color: #000000; font-style: normal; font-variant: normal;"><em>Light-cured resin composite is one of the most commonly used molding materials due to its easy-to-mold characteristic. </em><span style="font-family: TribuneItalic; font-size: 9pt; color: #000000; font-style: normal; font-variant: normal;"><em>Nevertheless, care must be taken while treating this material, especially with respect to material thickness and how long it is </em><span style="font-family: TribuneItalic; font-size: 9pt; color: #000000; font-style: normal; font-variant: normal;"><em>exposed to light. Failure to treat the material with these optimal parameters will result in undesired hardness. To determine the most </em><span style="font-family: TribuneItalic; font-size: 9pt; color: #000000; font-style: normal; font-variant: normal;"><em>favorable value of these two parameters, an experiment was done with 3 different material thicknesses, and 3 different exposure </em><span style="font-family: TribuneItalic; font-size: 9pt; color: #000000; font-style: normal; font-variant: normal;"><em>times. After the sample of the resin composite was removed from its molding, it was stored under humid condition for 24 hours. </em><span style="font-family: TribuneItalic; font-size: 9pt; color: #000000; font-style: normal; font-variant: normal;"><em>Afterwards hardness test was done on the sample using Micro Vickers Hardness tester from this experiment, the significant difference </em><span style="font-family: TribuneItalic; font-size: 9pt; color: #000000; font-style: normal; font-variant: normal;"><em>in hardness was obtained and the maximum hardness was evaluated from the resin composite sample with 2 mm thickness and 60 </em><span style="font-family: TribuneItalic; font-size: 9pt; color: #000000; font-style: normal; font-variant: normal;"><em>seconds light exposure.</em></span></span></span></span></span></span></span><br style="font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: -webkit-auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px;" /></span> |
