Histological assessment of pulpal responses to resin modified glass ionomer cements in human teeth.

Background: The biocompatibility of resin-modified glass ionomers (RMGIs) as a lining material is still under question. The present study evaluated the response of the pulp-dentin complex following application of resin-modified glass-ionomer cement, calcium hydroxide and conventional glass-ionomer in deep cavities prepared in human teeth.

Materials And Methods: In this controlled clinical trial, 30 deep class V buccal cavities (3 mm × 2 mm × 2 mm) were prepared in human premolars treatment planned to be extracted for orthodontic reasons and divided into 3 groups.

Effect of surface treatments on fracture resistance of root filled teeth with bonded fibre posts.

Background/aim: This study examined the effect of several dentin surface treatments on fracture resistance of root filled teeth containing bonded fibre posts.

Material And Methods: The roots of 84 single-canal premolars were instrumented, filled with gutta-percha and randomly divided into seven groups. The coronal 9 mm of gutta-percha was removed to create a post space.

Risk of Contamination of Different Areas of Dentist's Face During Dental Practices.

Background: Dental practice presents opportunities for cross-contamination. The dentist's face is at high-risk of infection transmission. The purpose of this study was to evaluate the risk of contamination in different areas of dentist's face during dental practices.

Effect of base metal alloys recasting on marginal integrity of castable crowns.

Introduction: Base metals have a wide use in casting methods. Sometimes they are reused in laboratories which may have an adverse effect on the restoration marginal integrity. This study aimed to investigate the effect of recasting of alloys on marginal integrity of restorations.

Effects of immediate orthodontic and orthopedic forces on peri-miniscrew bones: histomorphologic and histomorphometric assessment in dogs.

Aim. The aim of this study was histomorphologic and histomorphometric evaluation of peri-screw bone after immediate orthodontic and orthopedic forces and comparing them with a control group. Materials and Methods.

Accuracy of linear measurements of galileos cone beam computed tomography in normal and different head positions.

Introduction. The aim of this study was to determine the accuracy of linear measurements in dry human skulls in ideal position and different deviated positions of the skull. Methods.

Microflora around teeth and dental implants.

Background: When an implant is exposed to oral cavity, its surface gets colonized by micro-organisms. The aim of this study is to comparatively assess the microbiological parameters in sulci around the teeth and the crowns supported by dental implants.

Materials And Methods: In this prospective, cross-sectional study, 34 partially edentulous patients aged between 40 and 50 years with total 50 anterior maxillary single implants with cemented crowns (depth of sulci <4 mm) and 34 similar teeth in the same jaw of the same patients were included.

The Effectiveness of GECB Pastille in Reducing Complications of Dry Socket Syndrome.

Background and Purpose. Dry socket syndrome is one of the most irritating complications after tooth extraction. This study aims to investigate the efficacy of pastille GECB compared to ZOE.

Evaluation of microgap size and microbial leakage in the connection area of 4 abutments with Straumann (ITI) implant.

A microgap between implant and abutment can lead to mechanical and biological problems such as abutment screw fracture and peri-implantitis. The aim of this study was to evaluate microgap size and microbial leakage in the connection area of 4 different abutments to ITI implants. In this experimental study, 36 abutments in 4 groups (including Cast On, Castable, Solid, and Synocta abutments) connected to Straumann fixtures (with their inner part inoculated with bacterial suspension) and microbial leakage were assessed at different times.
