fa Effect of surface treatment with Er Cr:YSSG, Nd:YAG, and CO2 lasers on repair shear bond strength of a silorane-based composite resin ترمیمی Cosmetic and Restorative Dentistry پژوهشي Research <b> Background and aims.</b> The aim of the present study was to compare the effect of surface treatment with Er Cr:YSSG, Nd:YAG, and CO2 lasers on repair shear bond strength of a silorane-based composite resin. <div><b>Materials and methods</b>. Sixty eight cylindrical samples of a silorane-based composite resin (Filtek Silorane) were prepared and randomly divided into 4 groups as follows: group 1: without surface treatment groups 2, 3 and 4 with surface treatments using Er Cr:YSSG, Nd:YAG, and CO2 lasers, respectively. A positive control group (group 5) was assigned in order to measure cohesive strength. Repair shear bond strength values were measured and data was analyzed using one-way ANOVA and a post hoc Tukey test at a significance level of α=0.05.</div><div>  <b>Results.</b> There were statistically significant differences in repair shear bond strength values between group 2 and other groups (P < 0.05) and between group 1and groups 3and 4 (P < 0.001) however, there were no significant differences between groups 3 and 4 (P = 0.91).</div><div>  <b>Conclusion</b>. The repair shear bond strength of silorane-based composite resin was acceptable by surface treatment with lasers.</div><hr><p class="MsoNormal" style="text-align: left direction: ltr unicode-bidi: embed"><b>Source: </b>Journal of Dental Research, Dental Clinics, Dental Prospects </p> <p class="MsoNormal" style="text-align: left direction: ltr unicode-bidi: embed"><a href="http://dentistry.tbzmed.ac.ir/joddd/index.php/joddd/article/view/465" target="_blank"><font color="#0000ff">Full Text</font></a></p> Laser, Silorane based composite resin, Surface treatment 0 0 http://idai.ir/browse.php?a_code=A-10-32-3224&slc_lang=fa&sid=1 Parnian Alizade Oskoee parnianoskuee@yahoo.com 100319475328460014856 100319475328460014856 Yes Dntal and Periodontal Research Center, Tabriz University of Medical Sciences, Tabriz, Iran/Department of Operative Dentistry, Faculty of Dentistry, Tabriz University of Medical Sciences, Tabriz, Iran Narmin Mohammadi 100319475328460014857 100319475328460014857 No Department of Operative Dentistry, Faculty of Dentistry, Tabriz University of Medical Sciences, Tabriz, Iran Mohammad Esmaeel Ebrahimi Chaharom 100319475328460014858 100319475328460014858 No Department of Operative Dentistry, Faculty of Dentistry, Tabriz University of Medical Sciences, Tabriz, Iran Soodabeh Kimiyai 100319475328460014859 100319475328460014859 No Department of Operative Dentistry, Faculty of Dentistry, Tabriz University of Medical Sciences, Tabriz, Iran Fatemeh Pournaghi Azar 100319475328460014860 100319475328460014860 No Department of Operative Dentistry, Faculty of Dentistry, Tabriz University of Medical Sciences, Tabriz, Iran Sahand Rikhtegaran 100319475328460014861 100319475328460014861 No Department of Operative Dentistry, Faculty of Dentistry, Tabriz University of Medical Sciences, Tabriz, Iran Maryam Shojaee 100319475328460014862 100319475328460014862 No Department of Operative Dentistry, Faculty of Dentistry, Qazvin University of Medical Sciences, Qazvin, Iran
