Abstract Objective: To test the null hypothesis that presence of dehiscence and fenestration was not different among patients with skeletal Class I, II, III malocclusions. Materials Methods: In this retrospective study, a total 123 cone-beam computed tomography (CBCT) images were obtained an iCAT scanner (Imaging Sciences International, Hatfield, Pa). Patients normal vertical patterns classified according to dental malocclusion ANB angle. I comprised 41 patients—21 girls 20 boys (mean age,...

To test the null hypothesis that presence of alveolar defects (dehiscence and fenestration) was not different among patients with vertical growth patterns.A total 1872 teeth in 26 hyper-divergent (mean age: 24.4 ± 4.8 years), 27 hypo-divergent 25.1 4.5 25 normo-divergent 23.6 4.1 years) no previous orthodontic treatment were evaluated using cone-beam computed tomography. Axial cross-sectional views regard to whether dehiscence and/or fenestration on buccal lingual surfaces existed or not....

The aim of this study was to test nano-composite (Filtek Supreme Plus Universal) and a newly introduced nano-ionomer (Ketac™ N100 Light Curing Nano-Ionomer) restorative determine their shear bond strength (SBS) failure site locations in comparison with conventional light-cure orthodontic bonding adhesive (Transbond XT). Sixty freshly extracted human maxillary premolar teeth were arbitrarily divided into three equal groups. brackets bonded the each group different composites, according...

The aim of this study was to evaluate soft tissue differences between Turkish and North American adults by comparing two sample populations with ideal occlusion well-balanced faces. Lateral cephalometric radiographs 117 Anatolian (65 female 52 male, mean age: 23.9 ± 2.8 years) were compared a 116 European-American ancestry (64 25.0 6.8 years). analyses Holdaway, Epker, Legan Burstone performed using Dolphin Image Software 9.0. Thirty-two measurements (27 linear 5 angular) analysed. For...

The aims of this study were to evaluate intra-examiner repeatability and inter-examiner reproducibility landmarks using two cephalometric analysing techniques, manual computerized, compare these for speed. One hundred lateral radiographs randomly selected 11 angular six linear parameters traced measured by examiners the method Dolphin Image Software 9.0 on each radiograph. A Student's t-test paired independent samples was used mean values intra- differences. Intraclass correlation...

The aims of this study were (1) to establish standards for Arnett soft tissue cephalometric analysis Anatolian Turkish young adults and (2) identify possible gender differences between males females. After analysing the radiographs 350 individuals, 133 subjects (67 males, mean age 22.6 ± 2.2 years, 66 females, 22.1 2.6 years) with normal antero-posterior vertical skeletal relationships selected. true line was established. landmarks marked facial performed. For statistical evaluation, an...

To test the null hypothesis that there is no significant difference between chitosan-containing and conventional nonfluoridated dentifrices in inhibition of enamel demineralization around orthodontic brackets.Sixteen patients who were scheduled to have extraction four first premolars for reasons divided into two groups after power study was estimated. Patients experimental group instructed use dentifrice (AloeDent), control (Sensodyne Mint). After 60 days, teeth extracted longitudinally...

The aim of this follow-up study was to evaluate the effects Pre-Orthodontic Trainer (POT) appliance on anterior temporal, mental, orbicularis oris, and masseter muscles through electromyography (EMG) evaluations in subjects with Class II division 1 malocclusion incompetent lips. Twenty patients (mean age: 9.8 ± 2.2 years) a were treated POT (Myofunctional Research Co., Queensland, Australia). A group 15 9.2 0.9 untreated malocclusions used as control. EMG recordings treatment taken at...

The aim of this study was to compare the measurements performed with digital manual (DM) cephalometric analysis and automatic obtained from an online artificial intelligence (AI) platform, according different sagittal skeletal malocclusions.Cephalometric radiographs 105 randomly selected individuals (mean age: 17.25 ± 1.87 years) were included in study. Dolphin Imaging software used for DM analysis, WebCeph platform AI-based analysis. In total, 10 linear 12 angular evaluated. paired t-test,...

The aim of this in vitro study was to compare microleakage orthodontic brackets between enamel–composite and composite–bracket interfaces at the occlusal gingival margins, bonded using indirect bonding systems with that a conventional direct method. Forty freshly extracted human maxillary premolar teeth were randomly divided into two groups. In group 1, directly according manufacturer's recommendations. Group 2 consisted 20 indirectly Transbond XT (3M-Unitek), as adhesive, Sondhi Rapid Set...

The aim of this study was to evaluate the relationship between tongue volume and lower incisor irregularity, using cone-beam computed tomography (CBCT), identify possible gender differences. CBCT images 60 patients 16 36 years age were selected from 1400 sets in database. Tomography carried out iCAT® (Imaging Sciences International, Hatfield, Pennsylvania, USA) segmentation by Mimics 10.1 software (Materialise NV, Leuven, Belgium). calculated voxels scan number for a given mask.

Abstract Background Investigating the effects of 405-nm, 532-nm, 650-nm, and 950-nm wavelengths LLLTs (low-level laser therapies) on orthodontic tooth movement in rats by using histological immunohistochemical methods. Forty-five Wistar albino were randomly divided into 5 groups: control group (positive control: left maxillary 1st molar side; negative right side), 405 nm LLLT (Realpoo), 532 650 940 (Biolase). The teeth all applied mesially 50-g force. Starting from day, 48 h intervals, was...
