The aim of this experimental study was to evaluate
the effects of light-emitting diode-mediated-photobiomodulation
therapy (LPT), on the rate of orthodontic tooth movement (TM)
and orthodontically induced root resorption, in rats. Twentymale
12-week-oldWistar rats were separated into two groups (control
and LPT) and 50 cN of force was applied between maxillary left
molar and incisor with a coil spring. In the treatment group, LPT
was applied with an energy density of 20 mW/cm2 over a period
of 10 consecutive days directly over the movement of the first
molar teeth area. The distance b ...Daha fazlası
Objective: To evaluate the changes in cortical bone thickness, alveolar bone
height, and the incidence of dehiscence and fenestration in the surrounding
alveolar bone of posterior teeth after rapid maxillary expansion (RME) treatment
using cone-beam computed tomography (CBCT). Methods: The CBCT records of
20 subjects (9 boys, mean age: 13.97 ± 1.17 years; 11 girls, mean age: 13.53 ±
2.12 year) that underwent RME were selected from the archives. CBCT scans had
been taken before (T1) and after (T2) the RME. Moreover, 10 of the subjects had
6-month retention (T3) records. We used th ...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
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
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
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
Introduction: The aim of this study was to evaluate the prevalence of bacteremia associated with an orthodontic
stripping procedure. Methods: The study included 29 orthodontic patients (mean age, 18.2 6 3.4 years). We
used a standardized stripping procedure: a perforated stripping disk with a contra-angle hand piece was used
at a low speed (\15,000 rpm; 10 seconds) on the mandibular anterior teeth. Blood samples were collected
by inserting a cannula into the left antecubital fossa. A baseline sample was taken before treatment, and
a second sample was taken after the stripping procedure. T ...Daha fazlası
