Özet (Çeviri)
Aim. The an11 of this retrospective study was to investigate external apical root resorption occured during fixed orthodontic treatment with or without extraction cases with different type of malocclusions.Material and Method. In this study, panoramic radiographs of cases with Angle Class I, Angle Class II division I, Angle Class II division 2 and Angle Class III malocclusion treated with extraction or non-extraction fixed orthodontic treatment were used. The effect of malocclusion type, extraction/non-extraetion treatments and gender on external root resorption of maxillary incisors in patients which are identical in terms ofchronologic age and treatment duration was evaluated. A total 400 patients were evaluated so that each malocclusion subgroup included 50 patients (25 male and 25 female) with extraction and 50 patients (25 male and 25 female) with non extraction theraphy . Drawings were made in N etcad 4.0 package program in order to determine the amount of external apical root resorption. Root length reduction was calculated in millimeters and external apical root resorption was evaluated in tem1S of the percentage ofthe original root length.Results. The 3-Way Analysis of Variance was used for statistical analysis. Shapiro Wilks test was applied to detem1ine the homogeneity of data. FUliher One way ANOVA test was used for the evaluation of the differences between malocclusion groups, Duncan test was used to determine sources of differences. Student's t-test was used in order to find out whether there were differences between extraction and nonextractiontreatment methods and bctwcen the genders. The result of the statistical evaluation indicated that, the type of malocclusion, the treatment method and gender havestatistically significant effect on external apical root resorption. Conclusion. As a result of this study, it has been found that external apical root resorption occured in maksillary incisors which underwent orthodontic therapy and the amount of external apical root resorption varied among malocclusion groups, extraction/non-extraction treatment groups and genders.
