Introduction Several attempts have been made to develop ceramic systems without metal frameworks. To date, there is an increasing range of dental ceramics allowing clinicians to combine very good esthetics with optimal mechanical properties, such as glass-infiltrated porcelain, aluminaand zirconia-reinforced ceramics . Several authors have described different surface treatments to improve the a...

PURPOSE More than half of the cavity restorations are replaced due to bacterial microleakage. A need for disinfection agents arises. Application of silver nanoparticles (AgNPs) may be beneficial, yet their impact on the adhesives' shear bond strength to dentin remains unknown. METHODS The aim was to assess the shear bond strength to dentin of different dental materials combined with AgNPs. Fa...

The aim of this work is to demonstrate the “dry” etching based micro-fabrication technologies in the manufacturing of Single Crystal Silicon (SCS) for Micro-Electro/(Optical)-Mechanical-Systems (ME(O)MS). The ME(O)MS technology is very fast growing industry branch based often on the same silicon technology as integrated circuits. The process of plasma-dry etching is quite simple straightforward...

The acid etch technique and the direct bonding of orthodontic attachments have become accepted procedures in clinical orthodontics. Changes are produced in enamel surface topography by acid etching and on removal of the bonded attachments at the end of treatment. These changes were examined by scanning electron microscopy and the clinical im­ plications of these surface changes are discussed. O...

Aim: To evaluate the effect of 2% Chlorhexidine on antibacterial activity on Resin cement. Methods: A total of 100 patients of 29-56 years of age who required Fixed dental Prosthesis were selected for the study. 2 teeth were prepared in each patient for All Ceramic crowns. In every patient, the 2 teeth prepared were divided in to 2 groups: Control(no antimicrobial agent applied after etching of...

Esthetics has been an indispensable element in human life for centuries. The elimination of esthetic problems substantially aids in confident self-expression. In addition to the different departments dealing with esthetics in medicine, orthodontists also make arrangements to eliminate various esthetic and functional concerns. These arrangements include the correction of skeletal and dental anom...

 Thinning of micromachined wafers containing trenches and cavities to realize through-chip interconnects is presented. Successful thinning of wafers by lapping and polishing until the cavities previously etched by deep reactive ion etching are reached is demonstrated. The possible causes of damage to the etched structures are investigated. The trapping of particles in the cavities is studied a...

BACKGROUND Air-abrasion can be used for enamel preparation before fissure sealing as well as acid etching which is the evidence-based method for enamel preparation before sealing. AIM The aim of this study is to evaluate the status of sealed occlusal surfaces of the first permanent molars after one, two, and five years and to compare consequence of using the two different methods for enamel p...
