introduction: although dental caries is a preventable disease, it is still common and remains a public health problem. one of the potentially effective preventive measures is the use of lasers. the purpose of this study was to review the studies about use of laser irradiation on the inhibition of carious lesions and the effectiveness of different commercial laser type (nd:yag, co2, and argon). ...
Background and Aims: Indirect composites are designed to overcome the shortcomings of direct composites such as polymerization shrinkage and low degree of conversion. But, good adhesion of resin cements to indirect composites is still difficult. This research was designed to assess the effect of different powers of ErYAG laser compared with sandblasting. On the micro tensil bond strength of r...
apart from other aspects, desert is a natural environment and is one of the appealing terrestrial elements. putting its symbolic and fictional senses aside, the term “desert” bears mystic sense more than material sense. in addition to the worlds materialistic experiences, desert has attracted the attention of writers because it creates a kind of inner experience, which returns the individual in...
Introduction: In order to increase the bonding strength of the composite resin cements to the indirect composites, experiments such as the creation of surface roughness with sandblasting, acid-etching, silane application, laser, etc. have been carried out. However, there is no consensus about the results. Therefore, the purpose of this study was to investigate the effect of Er: YAG and Nd: YAG ...

Today laser has become a standard tool in modern minimal invasive microneurosurgery and it is being increasingly used in functional neurosurgery as well. Lasers have found their full and extensive application for their capacity of acting on pathological tissues without direct contact, through relatively small craniotomy, and in deep hardly accessible regions. In accordance with worldwide experi...
