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 Pharyngeal airway and hyoid bone position changes of skeletal anchored Forsus Fatigue Resistant Device and activator appliances(2021) Ince-Bingol, Sinem; Kaya, Burcak; https://orcid.org/0000-0002-7014-0784; 33449194Objectives To evaluate the effects of miniplate anchored Forsus Fatigue Resistant Device (MAF) and activator treatments in the pharyngeal airway dimensions and hyoid bone position. Materials and methods Thirty-eight patients with mandibular retrusion who were treated with either MAF or activator were selected retrospectively and compared with an untreated control group. The data of 114 lateral cephalograms, comprising those taken before treatment (T1) and at the end of functional treatment (T2), were evaluated with regard to their linear, angular, and area measurements. Results The mandibular length increased and the hyoid bone moved forward with both treatments (P < 0.05). The horizontal change in the hyoid bone position with MAF treatment was correlated with changes in the point B and ANB angle. Increases of 1.8 mm, 1.4 mm, and 1.8 mm in the pharyngeal airway dimensions were obtained at the levels of the second, third, and fourth cervical vertebra, respectively, with the MAF treatment. On the other hand, an increase of 1.9 mm was found at the level of the fourth cervical vertebra with the activator treatment. The greatest vertical movement in the Menton and the highest increase in the oropharyngeal area were observed in the MAF group (P < 0.05). Conclusion Both the MAF and activator treatments caused favorable maxillomandibular changes; however, the MAF treatment provided a greater increase in the oropharyngeal area according to both the increase in mandibular length and the change in the vertical position of the mandible. Clinical relevance Functional appliances were found to be useful in increasing the pharyngeal airway dimensions in the shortterm. The skeletal anchored fixed functional appliance caused a greater increase in the oropharyngeal airway area that may be beneficial for Class II patients who carry a risk of having respiratory problems.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 Effect of maxillary incisors, lower lip, and gingival display relationship on smile attractiveness(2020) Tosun, Hande; Kaya, Burcak; 32115112Introduction: This study aimed to evaluate the effect of the relationship between maxillary incisors and lower lip in conjunction with the maxillary gingival display on perception of smile attractiveness. Methods: The frontal intraoral photograph of ideally aligned teeth was modified using image processing software. Twenty different smiles were obtained with a combination of 10 different maxillary incisor edge-lower lip distances and 10 different maxillary gingival display amounts. Attractiveness of these 20 smiles was evaluated by orthodontists (n = 101), dentists (n = 107), and laypersons (n = 105). Two-way ANOVA was used to compare alterations on smile esthetics, and repeated measures ANOVA was used to evaluate the interaction between the variables. Bonferroni-adjusted pairwise comparisons were applied for determining the differences between the rater groups. Results: Maxillary incisor edge-lower lip distance (P < 0.01), maxillary gingival display amount (P < 0.001), and rater group (P < 0.01) had statistically significant influences on perception of smile attractiveness. Orthodontists prefer to see a minimal amount of mandibular incisor exposure and almost full crowns of maxillary central incisors. Dentists and laypersons are more tolerant of mandibular incisor exposure and maxillary central incisor coverage by the upper lip. None of the rater groups preferred the coverage of maxillary incisor edges or maxillary gingival display. Conclusions: Elimination of maxillary gingival display helps to improve smile attractiveness, whereas the coverage of maxillary incisor edges has a negative influence.Item Corrections, clarifications, and explanations regarding malocclusion classification, and types of miniplates utilized(2020) Cubuk, Secil; Kaya, Burcak; 32588112Item Treatment efficiency of activator and skeletal anchored Forsus Fatigue Resistant Device appliances(2020) Ince-Bingol, Sinem; Kaya, Burcak; Bayram, Burak; Arman-Ozcirpici, Ayca; 0000-0002-7014-0784; 32671559Objectives The aim of the study was to investigate the treatment efficiency of miniplate anchored Forsus Fatigue Resistant Device (MAF) as compared with the activator appliance. Materials and methods Mandibular retrognathia was treated with two methods, the MAF group (8 girls, 11 boys, mean age 13.03 +/- 0.69 years) and the activator group (7 girls, 12 boys, mean age 12.68 +/- 0.73 years). An untreated control group (9 girls, 10 boys, mean age 12.95 +/- 0.73 years) was constructed to eliminate growth-related changes through the American Association of Orthodontists Foundation Legacy Collection. Data of 114 lateral cephalograms were analyzed. Results The inhibition of the maxillary growth was greater in the MAF group, whereas forward displacement of the mandible was higher in the activator group (P < 0.05). Sagittal maxillomandibular relation was improved similarly in both treatment groups (P < 0.05). Mandibular length was increased in both treatment groups with the highest increase in the activator group (P < 0.05). Retroclination of the incisors was observed in the MAF group (P < 0.05). The upper lip was retruded in the MAF group and lower lip was protruded in the activator group (P < 0.05). Conclusion The activator created greater mandibular changes, whereas the MAF provides somewhat smaller mandibular changes due to the restriction caused by retroclined maxillary incisorsItem Comparative evaluation of periodontal effects and survival rates of Memotain and five-stranded bonded retainers A prospective short-term study(2020) Kartal, Yasemin; Kaya, Burcak; Polat-Ozsoy, Omur; 32780168Purpose To prospectively compare the short-term periodontal effects and survival rates of mandibular lingual canine-to-canine Memotain (CA-Digital, Mettmann, Germany) and five-stranded bonded retainers. Methods In all, 52 patients requiring retention after orthodontic treatment were assigned to 2 study groups (n = 26 in each group). Retention was provided by Memotain retainers which were fabricated digitally using CAD-CAM (computer-aided design and computer-aided manufacturing) technology in the first group and by five-stranded retainers which were fabricated manually using a conventional bending method in the second group. The patients were examined at the following time points: 1 week, 1 month, 3 months and 6 months. Plaque index, gingival index, probing depth, marginal recession, bleeding on probing, failure rate per tooth, and survival rate of retainer wires were analyzed by Mann-Whitney U, Friedman, Wilcoxon signed-rank, and chi(2) tests. Results The differences between the groups were nonsignificant for plaque index, gingival index, probing depth, marginal recession, bleeding on probing, failure rate per tooth and survival rate of retainer wires. Significant differences were observed within the groups throughout the follow-up period for plaque index and probing depth. The survival rates of retainer wires were 77% for the Memotain retainers and 73% for the five-stranded retainers for the 6-month follow-up period. Conclusions Periodontal outcomes and survival rates of Memotain and five-stranded mandibular lingual bonded retainers were similar. Furthermore, periodontal health was maintained and considerably high survival rates were achieved with both retainer types.
