Objectives: The aim of this study was to evaluate differences in craniofacial morphology,
head posture and hyoid bone position between mouth breathing (MB) and nasal breathing
(NB) patients.
Methods: Mouth breathing patients comprised 34 skeletal Class I subjects with a mean age of
12.8 ± 1.5 years (range: 12.0–15.2 years). Thirty-two subjects with skeletal Class I relationship were
included in the NB group (mean 13.5 ±1.3 years; range: 12.2–14.8 years). Twenty-seven measurements
(15 angular and 12 linear) were used for the craniofacial analysis. Additionally, 12 measurements
were evalu ...Daha fazlası
Objective: To evaluate lower incisor position and bony support between
patients with Class II average- and high-angle malocclusions and compare
with the patients presenting Class I malocclusions. Methods: CBCT records of
79 patients were divided into 2 groups according to sagittal jaw relationships:
Class I and II. Each group was further divided into average- and high-angle
subgroups. Six angular and 6 linear measurements were performed. Independent
samples t-test, Kruskal–Wallis, and Dunn post-hoc tests were performed for
statistical comparisons. Results: Labial alveolar bone th ...Daha fazlası
To evaluate the shear bond strength (SBS), fracture mode, wire pull out (WPO) resistance and microleakage between low-shrinking and conventional composites used as a lingual retainer adhesive. Methods: A total of 120 human mandibular incisor teeth, extracted for periodontal reasons, were collected. Sixty of them were separated into two groups. To determine the SBS, either Transbond-LR (3M-Unitek) or Silorane (3M-Espe) was applied to the lingual surface of the teeth by packing the material into standard cylindrical plastic matrices (Ultradent) to simulate the lingual retainer bonding area. To t ...Daha fazlası
