Evaluate Bioactive Orthodontic Adhesive with Fluorescence Property

Abstract

Objectives: This study aimed to assess the effect of adding fluorescent dyes to bioactive orthodontic adhesive by measure the degree of conversion & the shear bond strength. Materials and Methods: Bioactive BEAUTIFIL Injectable XSL (S-PRG), from (GIOMER, SHOFU, JAPAN) mixed with Flourcence dye (Strontium aluminate), White Glow in the Dark Powder from (Techno Glow Inc., USA) which glows up for long time. using in 5%, 10% & 15% of weight concentrations. For degree of conversion (DC) we prepared 40 disc-shaped sample for 4 groups (with 10 sample for each) as following: Group1: BEAUTIFIL Injectable XSL (control group), Group2: BEAUTIFIL Injectable XSL with 5% flourcence dye, Group3: BEAUTIFIL Injectable XSL with 10% flourcence dye & Group4: BEAUTIFIL Injectable XSL with 15% flourcence dye. The DC was determined by using Fourier Transform Infrared spectrophotometer FTIR (ALPHAII PLATINUM-ATR. Bruker. GERMANY). For shear bond strength (SBS) 40 samples prepared & divided into 4 groups with 10 samples as following: Group1: BEAUTIFIL Injectable XSL (control group), Group2: BEAUTIFIL Injectable XSL with 5% flourcence dye, Group3: BEAUTIFIL Injectable XSL with 10% flourcence dye & Group4: BEAUTIFIL Injectable XSL with 15% flourcence dye. The shear strength measured by Instron Testing Machine (Gester international. CHINA). Results: The use of fluorescent with bioactive adhesive show statistically no significant difference between groups. but there was decreasing in both DC & SBS with increase flourcence concentration. Conclusions: add fluorescence dye produce acceptable fluorescence-bioactive adhesive & with increase its concentration will increase time of plowing which in turn simplified the removal of remnant after complete treatment with decrease enamel damage.
