Item The Impact Of Dentofacial Characteristics And Malocclusions On Dissatisfaction With Dentofacial Appearance(CLINICAL ORAL INVESTIGATIONS, 2024-11-28) Ince-Bingol, Sinem; Kaya, BurcakObjectivesTo 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.Item Factors That May Increase The Risk of External Apical Root Resorption During Orthodontic Treatment Retrospective Clinical Investigation(2024) Kaya, Burcak; Gulsahi, Ayse; Turkyilmaz, GizemPurposeTo 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.Item Multidisciplinary management of an adult skeletal Class III patient with generalized aggressive periodontitis and canine-premolar transposition(2021) Ince Bingol, Sinem; Nisanci Yilmaz, Mediha Nur; Kaya, BurcakThis case report presents orthodontic camouflage treatment and the correction of transposed canine-first premolar teeth in a patient who presented with a skeletal Class III and familial periodontal problem. A 28-year-old female patient who was diagnosed with generalised aggressive periodontitis was treated by scaling and root planing plus the adjunctive use of systemic antibiotics and surgical therapy prior to referral to the orthodontic department. After the progression of the disease was controlled, orthodontic treatment was commenced to correct the dental transposition by using a modified Nance-TPA appliance and sectional arch mechanics. A non-extraction orthodontic camouflage treatment was planned to eliminate the anterior crossbite and to establish a proper occlusion by closing the multiple diastemata. Treatment outcomes remained stable in the 2-year follow-up period. Severe orthodontic-periodontal problems can be successfully treated by oral hygiene motivation, an interdisciplinary approach, and the selection of appropriate biomechanics.Item Fixed Orthodontic Retainers: A Review(2019) Kartal, Yasemin; Kaya, Burcak; 31294414Orthodontic retention is defined as maintaining teeth in optimal aesthetic and functional position after treatment. Despite the necessity of retention phase and the factors influencing the stability of the teeth after orthodontic treatment was discussed by the orthodontist for a long time, it is accepted that a retention phase is essential for stability of orthodontic treatment results nowadays. Therefore, the application of a suitable retention method is important both for prevention of relapse after orthodontic treatment and for increasing patient satisfaction. Removable appliances had been used for many years for retention purposes. Later, fixed retainers were introduced to prevent relapse as having a number of advantages, such as better aesthetics, no need for patient cooperation, effectiveness, and suitability for lifelong retention. However, their need for precise bonding technique, fragility, and tendency to cause periodontal problems by weakening oral hygiene are some of their disadvantages.Item Appraisal of the relationship between tooth inclination, dehiscence, fenestration, and sagittal skeletal pattern with cone beam computed tomography(2019) Coskun, Ipek; Kaya, Burcak; 30741575Objectives: To examine the relationship between sagittal facial pattern and dehiscence/fenestration presence in conjunction with buccolingual tooth inclination by using cone beam computed tomography. Materials and Methods: The study was carried out on the cone beam computed tomography scans of the following three groups of patients (n = 20 in each group): Class I, Class II, Class III. Buccolingual tooth inclination, buccal dehiscence/fenestration presence, and lingual dehiscence/fenestration presence were evaluated on each tooth. Analysis of variance, Kruskall-Wallis H, Scheffe, and chi-square tests were used for statistical comparisons. Results: Differences (P<.05) were observed between the groups for inclination of upper incisors and all lower teeth except for second molars. Dehiscence prevalence in the upper buccal and posterior buccal regions was higher (P<.05) in the Class I group when compared with the other groups. Lower buccal and anterior buccal regions showed higher (P=.0001) dehiscence prevalence in all groups. No difference was observed in fenestration prevalence between the groups. The upper buccal and anterior buccal regions showed higher (P=.0001) fenestration prevalence in all groups. Conclusions: Orthodontists must consider concealed alveolar defects in treatment planning to avoid gingival recession or tooth mobility.Item Periodontal effects and survival rates of different mandibular retainers: comparison of bonding technique and wire thickness(2019) Gokce, Begum; Kaya, Burcak; 31365926Objectives: This non-randomized prospective cohort study aimed to compare the periodontal effects and success rates of mandibular canine-to-canine fixed retainers having different bonding techniques and wire thicknesses. Materials and methods: Hundred patients requiring retention after orthodontic treatment were assigned to five study groups (n = 20 in each group, 61 females/39 males, median age range 16.5-18.0 years). Retention was provided by 0.0215"/direct, 0.0215"/indirect, 0.0175"/direct, 0.0175"/indirect bonded multistranded wires and removable Essix appliances. The primary and secondary outcomes were periodontal effects and success rates. The patients were examined in 1 week, 1 month, 3 months and 6 months follow-up appointments. Plaque index, gingival index, probing depth, marginal recession, bleeding on probing, failure rate per retainer wire and survival of retainer wires were analysed by Kruskal-Wallis H, Mann-Whitney U and chi-square tests. Results: Significant differences were observed between the fixed retainer (FR) and Essix (E) groups in gingival index scores at 1 month [mean FR: 1.13 (95% confidence interval (CI): 0.81-1.44), mean E: 0.40 (95% CI: 0.14-0.69), mean difference: 0.73, P < 0.01], 3 months [mean FR: 0.97/1.01 (95% CI: 0.65-1.30/0.72-1.30), mean E: 0.52 (95% CI: 0.25-0.82), mean differences: 0.45/0.49, P < 0.05], 6 months [mean FR: 0.94 (95% CI: 0.62-1.27), mean E: 0.35 (95% CI: 0.15-0.58), mean difference: 0.59, P < 0.05] and in bleeding on probing scores at 1 month [mean FR: 3.05 (95% CI: 2.12-3.98), mean E: 1.15 (95% CI: 0.42-1.88), mean difference: 1.90, P < 0.01]. The survival rates of retainer wires were 85 per cent for the 0.0215" direct/indirect and 90 per cent for the 0.0175" direct/indirect groups for the 6 months follow-up. Limitations: Six months follow-up period, which demonstrates only short-term outcomes. Conclusions: The periodontal outcomes or survival rates of mandibular fixed retainers were not affected by bonding technique or wire thickness, whereas gingival health improved with Essix retainers but not with fixed retainers.Item Cone Beam Computed Tomography in Orthodontics(2018) Kaya, Burcak; Coskun, Ipek; 30112468Orthodontists treat malocclusions by applying three-dimensional forces. For years, the diagnosis of this three-dimensional condition and the related treatment plan has been based on two-dimensional imaging. Lateral and anteroposterior cephalometric, panoramic, and periapical radiographs are some of the two-dimensional radiographs routinely used in orthodontics. Despite being highly beneficial in evaluating skeletal and dental relations, these radiographs fail to provide sufficient two-dimensional information in certain cases. The purpose of this compilation is to review the use of cone-beam computed tomography in orthodontics.
