| dc.description.abstract | Demineralization areas around the brackets observed during orthodontic treatment are of great interest for the orthodontist as demineralization of enamel adjacent to fixed orthodontic appliances can be an esthetic problem for the patient, as well as a problem for the doctor that overshadows the success of the treatment. A new Er:YAG laser handpiece (X-runner) is unique in its ability to digitally control size, shape and depth of irradiated enamel area. This study evaluated the enamel demineralization around brackets bonded following different etching techniques. In this study, total of 100 premolars were divided into four equal groups and received the following treatments: Group 1 Total Etch, acid etching; Group 2 Self Etch, self-etching; Group 3 Lazer M, manual Er:YAG laser etching; Group 4 Lazer X, Er:YAG laser etching with X-Runner handpiece. After placing the brackets, the teeth were cycled through a demineralization-remineralization procedure for 14 days. The solutions were changed daily in order to simulate the saliva flow in the mouth. The teeth were brushed manually with a soft-bristled toothbrush for 30 seconds between each cycle to simulate mechanical wear. The mineral loss on the enamel surface was assessed using Quantitative Light-Induced Fluorescence (QLF). As a result of analysis of QLF four different parameters including ∆F, ∆F max, ∆Q and Area were obtained. Kruskal Wallis test was used for comparisons of parameters between groups. Mann Whitney U test was used in the determination of the group that caused the differences. According to statistical evaluation of the results of QLF analysis there were significant differences among groups for four different parameters (p<0.01). In acid-etch group enamel demineralization around the brackets was significantly higher compared to other experimental groups (p<0.01). Furthermore, demineralization observed in X-runner group was significantly lower compared to manual Er:YAG laser group (p<0.05). There were no significant differences between other groups (p>0.05). Within the limitations of this study, Er:YAG laser etching with X-runner handpiece was considered to be favorable for prevention of enamel demineralization in vitro. | en |
