(2019)The aim of this study was to evaluate the effect of platelet-rich fibrin (PRF) membrane on tooth movement in comparison with shunt control and piezoelectric surgery. Sixteen White Vienna rabbits were included in the study ... -
Imaging Characteristics of Stafne Bone Cavity: Pictorial Essay
(2017)Background: Stafne bone cavities (SBCs) are typically seen on panoramic radiographs as unilocular, rounded or ovoid shaped, welldefined corticated radiolucencies that are located between the mandibular first molar and the ... -
Immune responses in women with periodontitis and preterm low birth weight: Levels of CD4+and CD8+T cells in gingival granulation tissue
(2020)Objective: Preterm Low-Birth-Weight (PLBW) is frequently associated with periodontal disease. However, the mechanism is still unknown. The present study was performed to examine the possible link between periodontal ... -
Impact of multiple firings and resin cement type on shear bond strength between zirconia and resin cements
(2020)PURPOSE. The aim of this study was to evaluate the effect of multiple firings on the bond strength between yttria-tetragonal zirconia polycrystals (Y-TZP) and 2 types of resin cements. MATERIALS AND METHODS. Sixty 3Y-TZP ... -
In Vitro Evaluation of Direct and Indirect Effects of Sonic and Ultrasonic Instrumentations on the Shear Bond Strength of Orthodontic Brackets
(2020)Objective: Sonic and ultrasonic instrumentations generate vibrations that may influence debonding characteristics. The objective of this in vitro study was to assess the direct and indirect effects of sonic and ultrasonic ... -
Incidence of root canal treatment of second molars following adjacent impacted third molar extraction
(2016)Background/purpose: The aim of this study was to evaluate the incidence of requirement for root canal treatment of adjacent second molars following the surgical extraction of an impacted third molar. Materials and ... -
Indirect Bonding Revisited
(2016)In recent years, the popularity of indirect bonding increased due to advantages such as reduction of chair time and enhancement of patient comfort. Although the indirect bonding technique has improved over the years, the ... -
The influence of zirconia coping designs on maximum principal stress distribution in all-ceramic premolar crowns: A finite element analysis
(2019)Purpose: To evaluate the effects of different coping designs on maximum principal stresses in the veneering material using a finite element analysis method. Methods: A maxillary first premolar tooth model was prepared. The ... -
Investigation of SOSTDC1 gene in non-syndromic patients with supernumerary teeth
(2018)Background: The etiology of supernumerary teeth is still unclear however heredity is believed to be a major factor and this idea was supported by several case reports. Recently, a relationship between supernumerary tooth ... -
Lactobacillus rhamnosus could inhibit Porphyromonas gingivalis derived CXCL8 attenuation
(2016)An increasing body of evidence suggests that the use of probiotic bacteria is a promising intervention approach for the treatment of inflammatory diseases with a polymicrobial etiology. P. gingivalis has been noted to have ... -
Lingual Treatment of an Adult Patient with a Simplified Extraction Protocol
(2018)Successful orthodontic treatment of adult cases depends on the biological, mechanical, and esthetic requirements of patients. While customized lingual appliance systems meet the esthetic expectations of the patients, they ... -
Marginal Adaptation of Provisional CAD/CAM Restorations Fabricated Using Various Simulated Digital Cement Space Settings
(2018)Purpose: The ideal digital cement space value for the fabrication of provisional computer-aided design/ computer-aided manufacturing (CAD/CAM) crowns with clinically acceptable marginal adaptation is not well known. The ... -
Marginal fit of CAD-CAM monolithic zirconia crowns fabricated by using cone beam computed tomography scans
(2020)Statement of problem: Information regarding the precision of monolithic zirconia crowns fabricated by using a standard computer-aided design and computer-aided manufacturing (CAD-CAM) workflow is available. However, ... -
