COMPARISON THE DIFFERENT TYPES OF BONDING TECHNIQUES EFFECTS ON WHITE SPOT LESION FORMATIONTaner OZTURK*, Onur Aykan ATILLA**, Mustafa Murat ERUZ***, Ahmet YAGCI** Erciyes University, Faculty of Dentistry, Department of Orthodontics, Kayseri, Turkey**Osmanli Dental Center, Republic of Turkey Ministry of Health, Ankara, Turkey*** Private Practice, Kayseri, TurkeyBackground: White spot lesions (WS) are a frequent side effect of the fixed orthodontic treatment. This prospective study aimed to evaluate any difference between the formation of white spot lesion with indirect and direct bonding in patients who treated by fixed orthodontic treatment.Material&amp;Method: The records of 20 patients evaluated who were randomly distributed among the groups as indirect bonding group (n:10) and direct bonding group (n:10). All patients were treated with non-extraction orthodontic treatment throughout a mean of 1,5&plusmn;0,6 years. The records were taken by the quantitative light-induced fluorescence (QLF) method to determine enamel demineralization before and after treatment in the study. The images analyzed and fluorescence changes (&Delta;F, &Delta;Fmax, &Delta;Q and WS area) were recorded. &nbsp;Statistical evaluation of differences between groups at the end of treatment was made by Mann-Whitney U test. Wilcoxon signed rank test was used for intra-group comparisons.Results: After treatment, direct bonding group had a significantly higher value of fluorescence loss compared to indirect bonding group (p&lt;0,05). In the indirect bonding group, there was only a significant WSL formation in left mandibular canine.Conclusion: The use of indirect bonding techniques at the beginning of orthodontic treatment can reduce WSL formation.Keywords: White spot lesion, bonding technique, fluorescence loss</p
