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
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
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 the root resorption after rapid maxillary expansion (RME) via cone-beam
computed tomography (CBCT).
Materials and Methods: Records of 25 patients who had undergone RME with tooth-borne
banded expander were obtained from the archive of the orthodontic department. CBCT data were
reconstructed with surface and volume rendering, and the volumetric images were manipulated to
display the root surfaces from various orientations. On these three-dimensional images, permanent
first molars and first and second premolars were segmented, and their roots were isolated.

Objective: The purpose of this retrospective radiographic study was to determine the reliability and reproducibility of skeletal and
dental measurements of lateral cephalograms created from a computerised tomography (CT) scan compared with conventional
and digital lateral cephalograms.
Methods: CT and conventional lateral cephalograms of the same patients were obtained from university archives. The lateral
cephalometric radiographs of 30 patients were manually traced. The radiographs were subsequently scanned and traced using
Dolphin Imaging software version 11 (Dolphin Imaging, Chatswort ...Daha fazlası
Objective: To evaluate and compare the effects of enamel microabrasion, casein phosphopeptide-amorphous calcium phosphate (CPP-ACP), and their combination on the shear bond strength (SBS) of orthodontic brackets bonded to demineralized enamel surface.
Materials and Methods: One hundred human first premolar teeth were randomly allocated to one of five groups. Group I was considered as the control of other groups. For the remaining groups, demineralization was performed via solutions. In group II, brackets were directly bonded to the demineralized enamel surface. CPP-ACP was applied in group ...Daha fazlası
OBJECTIVE: The aim of this study is to evaluate dentoskeletal effects of Herbst and Twin Block (TB) appliance therapies in Skeletal Class II malocclusion.
SUBJECTS AND METHODS: Herbst group consisted of 11 girls and 9 boys (mean age = 12.74±1.43 years), TB group comprised of 10 girls and 10 boys (mean age = 13.0±1.32 years), and control group included 9 girls and 11 boys (mean age = 12.17±1.47 years). Mean treatment/observation times were 15.81±5.96 months for Herbst, 16.20±7.54 months for TB, and 15.58±3.13 months for control group. Pre-treatment (T0) and post-treatment (T1) lateral cephal ...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
Introduction: The aims of this study were to evaluate the effect of an antibacterial monomer-containing selfetching
adhesive in reducing enamel demineralization around orthodontic brackets in vivo and to compare it
with the conventional adhesive system quantitatively. Methods: Fourteen orthodontic patients were randomly
divided into 2 equal groups; they received brackets fitted to all their teeth, bonded with either Clearfil Protect
Bond (Kuraray Medical, Okayama, Japan) (experimental group) or Transbond XT (3M Unitek, Monrovia, Calif)
(control group). Block randomization to obtain equal ...Daha fazlası
INTRODUCTION:
The aim of this study was to test the null hypothesis that increased irregularity of the mandibular incisors is associated with a reduction in the alveolar support on cone-beam computed tomographic sections.
METHODS:
From a sample of 1100 digital volumetric tomographs, 125 tomographs of subjects with Class I malocclusion (mean age, 21.6 ± 4.8 years) were selected for this study. An irregularity index was used to categorize these tomographs as having mild, moderate, or severe crowding. All tomographs were taken by using an iCAT (Imaging Sciences International, Hatfield, Pa) ima ...Daha fazlası
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

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
