Fixed or removable orthodontic appliances impede the maintenance of oral hygiene and result in plaque accumulation. Plaque retention surrounding leads to enamel demineralization caused by organic acids produced bacteria dental plaque. Many studies have evaluated effects fixed on microbial flora periodontal status, but only a few method ligation as an additional factor. The aim this study was determine changes status after bonding whether two different archwire techniques affect these...

To investigate the utility of machine learning (ML) in accurately predicting orthodontic extraction patterns a heterogeneous population.The material this retrospective study consisted records 366 patients treated with extractions. The dataset was randomly split into training (70%) and test sets (30%) stratified according to race/ethnicity gender. Fifty-five cephalometric demographic input data were used train multiple ML algorithms. labelled previous treatment plan. Random Forest (RF),...

The purpose of the present study was to create a machine learning (ML) algorithm with ability predict extraction/non-extraction decision in racially and ethnically diverse sample.Data gathered from records 393 patients (200 non-extraction 193 extraction) population. Four ML models (logistic regression [LR], random forest [RF], support vector [SVM], neural network [NN]) were trained on training set (70% samples) then tested remaining samples (30%). accuracy precision model predictions...

There are many criteria and methods used to constitute determine a standardized esthetic concept in orthodontics. However, the subjectivity of is common opinion authors. Ethnic racial differences play major role diversifying preferences. The aims this study were general preference Turkish population find out whether was affected by sex, age, education, social status, geographic location, or personal profile. Toward these aims, eight profile estimates for each sex morphed video imaging...

This study was conducted to evaluate malocclusion and crowding in 1356 patients (793 girls, 563 boys) referred the Department of Orthodontics, Suleyman Demirel University, Turkey. Class I most frequently seen this Turkish orthodontic population whereas II, division 2 least seen. Comparison mean ages groups indicated statistically significant difference between 1 (P < .05). The lowest age present group. Mild mandibular common finding severe all groups. Cross tabulation maxillary that mild...

This study evaluates dental arch and alveolar widths of patients with Class II, division 1 malocclusion. Thirty female malocclusion were compared 30 subjects I ideal occlusion. Patients posterior crossbites even in a single tooth excluded from the study. According to our results, measured between maxillary second premolars first molars found narrower group, mandibular intercanine group. Interalveolar showed no difference groups. These results suggested that transverse discrepancy originated...

ABSTRACT Objective: This parallel controlled clinical trial evaluated the effect of a gel containing Lippia sidoides essential oil on plaque and gingivitis control. Methods: Thirty patients (n=30) were randomly selected allocated into three groups: (LS, n=10), chlorhexidine (CLX, n=10) or placebo (control, n=10). Plaque bleeding index recorded at baseline after months. All volunteers instructed to brush with times day throughout experiment period. Results: There was significant reduction in...

ABSTRACT Objective: To determine the effect of bracket type on halitosis, periodontal status, and microbial colonization. Materials Methods: Forty-six patients scheduled for fixed orthodontic treatment (age 11–16 years) were selected from department Suleyman Demirel University. Patients divided into two groups with random distribution brackets; 23 treated self-ligating brackets (group SLBs), others conventional CBs). Halitosis measurements records obtained before placement (T0), 1 week later...

To compare the skeletal, dentoalveolar, and soft tissue effects of miniplate anchored Forsus Fatigue Resistant Device (FRD) conventional FRD in treatment Class II malocclusion.The study was carried out with 30 patients (10 girls, 20 boys). In MA-Forsus group, 15 (2 13 boys) were treated a for 9.40 ± 2.25 months. C-Forsus (8 7 9.46 0.81 A total 16 measurements calculated statistically analyzed to find intragroup intergroup differences.Statistically significant differences found between groups...

Abstract Purpose The primary purpose of this study was to develop a new machine learning model for the surgery/non-surgery decision in class III patients and evaluate validity reliability model. Methods sample consisted 196 skeletal patients. All cases were allocated randomly, 136 training set remaining 60 test set. Using set, success rate artificial neural network estimated, along with 95% confidence interval. To predict surgical cases, we trained binary classifier using two different...

The aim was to predict the post-pubertal mandibular length and Y axis of growth in males by using various machine learning (ML) techniques. Cephalometric data obtained from 163 with Class I Angle malocclusion, were used train ML algorithms. Analysis variances (ANOVA) compare differences between predicted actual measurements among methods time points. All algorithms revealed an accuracy range 95.80% 97.64% while predicting length. When growth, accuracies ranged 96.60% 98.34%. There no...

This study aimed to predict long-term growth-related changes in skeletal and dental relationships within the craniofacial complex using machine learning (ML) models.

The aims of this study were to determine the prevalence tooth transposition in a Turkish population, possibly associated dental anomalies and whether side laterality, gender expression or genetic influence exist not.Panoramic radiographs 5486 patients referred Department Oral Diagnosis Radiology, University Suleyman Demirel between April 2003 March 2004 examined retrospectively. All with transpositions recalled for detailed clinical examination medical history. Age, sex, history (trauma),...

ABSTRACT Objective: To evaluate the effects of severity and location nonsyndromic hypodontia on craniofacial morphology. Materials Methods: A total 154 patients with at least two or more congenitally missing teeth were selected divided into groups (group I [mild]: to five teeth; group II [severe]: six teeth). The three according in dental arches (anterior, posterior, both anterior posterior) between jaws (maxilla, mandible, maxilla mandible). Fifty Class without any served as control group....

Studies evaluating maxillary and mandibular skeletal dental positions the vertical components of Class II patients have reported conflicting results. In addition, no common results been found regarding cranial base configurations. However, few studies evaluated nongrowing subjects. The aim this study was to establish whether with division 1 malocclusion specific craniofacial features. For this, 40 females were cephalometrically. Wide variations observed for almost all measurements patients....

Mandibular anterior crowding is identified as the discrepancy between mesiodistal tooth widths of four permanent incisors and available space in alveolar process. However, incisor not merely a tooth-arch size discrepancy. Many variables such direction mandibular growth, early loss deciduous molars, oral perioral musculature molar inclination can be associated with crowding. Only few studies evaluated relationship cephalometric measurements mixed dentition. It was aim this study to search for...
