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 study and compare the effects of different demineralizationinhibition
methods on the shear bond strength (SBS) and fracture mode of an
adhesive used to bond orthodontic brackets to demineralized enamel surfaces.
Methods: Eighty freshly extracted, human maxillary premolars were divided
into 4 equal groups and demineralized over the course of 21 days. Brackets were
bonded to the demineralized enamel of teeth in Group 1. In Group 2, bonding
was performed following resin infi ltration (ICON®, DMG, Hamburg, Germany).
Before bonding, pre-treatment with acidulated phosphate fluor ...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
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
Objectives: The aims of the present study were (1) to determine ethnic differences in craniofacial
dimensions between Turkish and Saudi populations and (2) to identify possible gender differences
between males and females, based on a sample of untreated young adult subjects with
normal occlusions and well-balanced faces.
Methods: In total, 163 cephalometric radiographs were traced and evaluated to compare
untreated adults of Turkish and Saudi ethnicity. The Turkish group comprised 86 subjects; 45
females and 41 males. The Saudi group comprised 77 subjects; 39 females and 38 males. For st ...Daha fazlası
Amaç: Nekrotik pulpalı immatür dişlerde kök ucunun açık olması, kök kanal sisteminin geniş ve kök ucuna doğru genişleyerek sonlanması nedeniyle bu dişlerde endodontik tedavi ile etkili bir apikal tıkama oluşturulması oldukça zordur. Bu yüzden bu dişlerin endodontik tedavilerinde kullanılacak kök kanal dolgu sisteminin apikal tıkama özelliği önem kazanmaktadır. Çalışmamızda hazırlanan simule immatür dişlerde yeni üretilmiş MTA Fillapex kanal dolgu patının Güta-perka ile birlikte kullanımı ve oluşturduğu apikal tıkamanın etkinliği Güta-perka/AH Plus kanal dolgu sistemi ile karşılaştırılarak in v ...Daha fazlası
Çocuk ve adolesanlarda konjenital olarak eksik veya travma nedeni ile kaybedilmiş daimi kesici dişlerden kaynaklanan problemlerin tedavisi için farklı yaklaşımlar mevcuttur. Bu olgu raporunda, alt ön keser dişleri konjenital olarak eksik olan hastaya uygulanan polietilen fiber ile güçlendirilmiş rezin tutuculu köprü sunumu amaçlanmıştır. On iki yaşındaki kız çoğuğu, bölümümüze diş eksikliğine bağlı estetik problem nedeni ile getirildi. Ağız içi ve radyolojik muayenesinden alt ön keser dişlerinin konjenital olarak eksik olduğu belirlendi. Komşu yan keser dişler bu bölgeye diastemalı olarak yerl ...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
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
Background: The aim of this study is to determine the relationship between the educational status of the parents who applied to the pediatric dentistry clinic and their approach to children’s oral-den- tal health. Methods: Questionnaire form with 8 question was used for parents. 226 parents which were selected randomly were included to the study. All parents gave their verbal assent to participation and infor- mation about questionnaire was given to them. The data were ana- lyzed by using chi-square tests. Results: The mean age for the mothers was 34,9, for the fathers was 39, for their childr ...Daha fazlası
Ehlers Danlos Syndrome (EDS) is a connective tissue disease that has effect on the structure and function of collagen. Collagen is a fibrous protein that is one of the main building structures of connective tissues such as skin, tendon, bone and cartilage. Connective tissue requires all type of collagen to function correctly.
People with EDS may show symptoms such as skin hyperelasticity, joint hypermobility, increased tendency to bruise and abnormal scarring. Dental findings have been reported with some types of EDS. This case report describes the dental findings of a patient (10, c?) who ...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
