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
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
Introduction: The aim of this study was to determine the peri-miniscrew implant crevicular fluid receptor
activator of nuclear factor-lB ligand (RANKL) and osteoprotegerin (OPG) levels around loaded and unloaded
miniscrew implants at different time intervals. Methods: Twenty loaded and 16 unloaded miniscrew implants
were included in this study. All miniscrew implants were placed bilaterally between the maxillary second premolars
and first molars as anchorage units for canine distalization. Peri-miniscrew implant crevicular fluid was taken
from the mesiobuccal aspects of the loaded and unl ...Daha fazlası
Objective –The aim of this study was to evaluate the effects of local resveratrol
(RSVL) administration on bone formation in response to expansion of the interpremaxillary
suture, in rats.
Material and Methods – Twenty 50- to 60-day-old male Wistar rats were separated
into two equal groups. Both groups were subjected to expansion, and 30 cN of force
was applied to the maxillary incisors with helical-spring. Twenty-four hours after
appliance placement, single-dose 10 lmol ⁄ kg RSVL in the dimethylsulfoxide
(DMSO) was injected to the inter-premaxillary suture in the experimental group. In ...Daha fazlası
The aim of this study was to investigate the efficiency of different diagnostic methods in detection of residual dentinal caries
in excavated cavities. Fifty extracted molar with deep dentinal carious lesions were excavated using a slow-speed handpiece.
All cavities were assessed by laser fluorescence(LF) device, electronic caries monitor(ECM), and caries detector dye(CDD) by
three independent observers blindly. The measurements were repeated after two weeks. Specimens containing dentin slices
150 μm in thickness were prepared for histological analyses. The existence and absence of car ...Daha fazlası
This in vitro study was to evaluate the erosive potential of four soft drinks at different times on bovine teeth by profilometry. Bovine incisors buccal side was sectioned with a diamond saw and a total of 100 enamel blocks were prepared (8 × 4 × 0.5 mm). Five specimens each were exposed to 60 ml of soft drinks (Sprite, Coca Cola, Cappy-orange and Ayran) for 15, 30, 60, 120 and 180 minutes in a continuously vibrating soft drinks bath in a beaker at room temperature. Surface loss of the specimens was determined with a profilometry. The data were analyzed by two-way analysis of variance and Tuke ...Daha fazlası
Horizontal root fractures are rare in comparison to other types of injuries and the reported
prevalence in the literature is between 0.5% and 7%. The treatment and prognosis of root
fractures depend on many variables, the most important being the length of time between trauma
and treatment, degree of dislocation and mobility, site of fracture, fixation period, stage of root
development, age of patient, and quality of treatment. The ideal healing type is hard tissue healing.
The aim of these case reports is to present four different patients who had horizontal root fractures
of imma ...Daha fazlası
