ABSTRACTEmergency conditions of ingestion foreign objects in dental practice may occur, one which is burs. Most the cases, object passes through digestive tract without difficulty, but some require surgery. Immediate removal be necessary because long-term retention leads to complications and even death. Case: 21 years old man underwent procedures, a few minutes after preparation, bur came off t...

background and aims. er:yag laser irradiation has been claimed to improve the adhesive properties of dentin; therefore, it has been proposed as an alternative to acid etching. the aim of this in vitro study was to investigate the shear bond strength of an etch-and-rinse adhesive system to dentin surfaces following er:yag laser and/or phosphoric acid etching. materials and methods. the roots of ...

THE advent of cavity-shaping technics, which utilize high rotational speeds and a light hand pressure to remove a large amount of tooth material, has resulted in an acute awareness by dental operators that certain burs are superior to others. This situation has caused an obvious desire by the dentist, the dental researcher and the manufacturer for knowledge which will explain these differences ...

BACKGROUND At the end of fixed orthodontic treatment, the remnant of adhesive should be eliminated from the tooth surface. The purpose of this study was to compare the effect of three methods of removing adhesive on enamel surface roughness, dental pulp temperature, and also on the time spent. MATERIALS AND METHODS The brackets on 90 extracted teeth were debonded using bracket removal pliers....

Purpose: This study aimed to evaluate the microleakage of glass ionomer restorations (GIC) in Class V cavities prepared with both conventional and Er: YAG laser techniques. Methods: Twenty teeth were used. Standard (4mm wide,3m high,3mm deep) on buccal lingual surfaces teeth. All randomly divided into four groups. In Groups II IV, by laser, I III conventionally a diamond bur. then restored GIC ...

Hypoxia stimulates excessive growth of vascular smooth muscle cells (VSMCs) contributing to vascular remodelling. Recent studies have shown that histone deacetylase inhibitors (HDIs) suppress VSMC proliferation and activate eNOS expression. However, the effects of HDI on hypoxia-induced VSMC growth and the role of activated eNOS in VSMCs are unclear. Using an EdU incorporation assay and flow cy...

Traditionally, it has been difficult to compare the clinical performance of carbide dental burs. The purpose of this laboratory study was to investigate the comparative cutting efficiency of number 330 dental burs from six manufacturers. These burs were tested utilizing custom-built equipment consisting of a frictionless air sled to which the Macor substrate was attached. The substrate was fed ...

BACKGROUND AND AIMS Seed yield and dormancy status are key components of species fitness that are influenced by the maternal environment, in particular temperature. Responses to environmental conditions can differ between ecotypes of the same species. Therefore, to investigate the effect of maternal environment on seed production, this study compared two contrasting Arabidopsis thaliana ecotype...
