    The Impact Of Dentofacial Characteristics And Malocclusions On Dissatisfaction With Dentofacial Appearance
    (CLINICAL ORAL INVESTIGATIONS, 2024-11-28) Ince-Bingol, Sinem; Kaya, Burcak
    ObjectivesTo assess how, and to what extent, dentofacial features and malocclusions affect the perceived dissatisfaction with the appearance of dentofacial region in different age groups.Materials and methodsDissatisfaction with dental appearance (DDA) and facial appearance (DFA) of 430 patients were assessed using self-reported 5-point Likert scores (1: very satisfied - 5:very dissatisfied). Number of decayed, filled, and missing teeth, oral hygiene status, crowding in the upper/lower arches, molar relationship, overjet, overbite, posterior-crossbite, upper/lower midline deviations, face type, profile, nasal tip and chin deviations were assessed by an experienced orthodontist. Ordinal logistic regression analysis was performed to determine how the examined variables affected DDA and DFA scores.ResultsThe median age of the 430 patients (271 female, 159 male) was 23.0 years. 60.9% of the patients had Angle Class I, 32.3% had Angle Class II, and 6.7% had Angle Class III molar relationship. According to the IOTN (DC), 37.4% of the patients had grade 4 and grade 5. Gender had no impact on DDA and DFA. Being young (teenagers OR = 4.78, CI:2.43-9.40, young adults (OR = 3.15, CI: 1.70-5.83), having poor oral hygiene (OR = 2.32, CI: 1.37-3.92), missing teeth (OR = 1.19, CI:1.10-1.29), convex profile (OR = 1.94, CI:1.03-3.67), diastema (OR = 3.18, CI:1.33-7.61), crowding in the upper arch (moderate: OR = 2.10, CI:1.30-3.68, severe: OR = 5.94, CI:3.15-11.19) affected the DDA scores negatively. Class III malocclusion (OR = 5.60, CI:1.85-16.91), decreased overbite (OR = 2.44, CI:1.21-4.89), and increase in DDA scores (OR = 1.88, CI: 1.50-2.35) all increased the DFA scores.ConclusionCertain dentofacial characteristics and age of the patients significantly affect self-reported dissatisfaction with dental and facial appearance levels, with varying degrees of severity.Clinical relevanceAwareness of the impacts of malocclusions and dentofacial features that result in patient dissatisfaction among those who apply for dental treatment at the clinic enables a deeper understanding of the patient's priorities, expectations from orthodontic treatment, and satisfaction with the outcome.

    Factors That May Increase The Risk of External Apical Root Resorption During Orthodontic Treatment Retrospective Clinical Investigation
    (2024) Kaya, Burcak; Gulsahi, Ayse; Turkyilmaz, Gizem
    PurposeTo determine the correlation between external apical root resorption and malocclusion-related variables in patients treated with fixed orthodontic appliances.MethodsIn all, 103 patients aged 12-15 years and treated with edge-wise appliances either without extractions or with four premolar extractions were included in this retrospective cohort study. External apical root resorption was assessed in the pre- and posttreatment panoramic radiographs of these patients for incisors, canines, premolars, and first molars. A total of 2332 teeth were evaluated in 206 panoramic radiographs obtained from 103 patients. The gender of the patients, duration of orthodontic treatments, presence of premolar extractions, Angle classification, overbite, overjet and amount of crowding were assessed. Wilcoxon signed-rank test, Mann-Whitney U test, and Kruskal-Wallis test were used for statistical analysis of the data.ResultsStatistically significant (p < 0.001) root resorption occurred in all examined teeth during orthodontic treatment. The degree of root resorption observed in the premolars was significantly greater in premolar extraction cases than in nonextraction cases. Statistically significant negative correlations were found between the degree of root resorption of the maxillary lateral teeth and between the maxillary first premolar teeth and the amount of maxillary crowding.ConclusionsThe orthodontic treatment protocols and the amount of tooth movements achieved were shown to be dependent on the severity of dental malocclusions and they have an influence on the amount of external apical root resorption that occurs during the course of orthodontic treatment.
