Nanomaterials have been studied in many products such as drug delivery, impression materials, restorative materials, dental implants, sensors, dental devices, and a widespread nanoparticles’ research has been done on various aspects of prosthetic dentistry. In dental materials, the nanoparticles are widely used in denture base materials, ceramics, implants, luting cements, and impression materi...

INTRODUCTION With increasing use of digital scanning with restorative procedures in the dental office, it becomes necessary that educational institutions adopt instructional methodology for introducing this technology together with conventional impression techniques. OBJECTIVE To compare the time differences between instructing dental students on digital scanning (DS) (LAVA C.O.S. digital imp...

BACKGROUND Bubbles and voids on the occlusal surface impede the actual intercuspation and pre-impression preparation aims to reduce the incidence of air bubbles and voids as well as influences the quality of occlusal reproduction and actual clinical intercuspation in the articulator. The study was undertaken to determine the influence of different pre-impression preparation procedures of antago...

INTRODUCTION Rhinolith, as the name indicates, is lithiasis or stone formation in the nose. The first well documented case of rhinolithiasis was reported by Barthdinin in 1654 [1]. Rhinoliths are completely or partially encrusted mineralized nasal masseseither exogenous or endogenous, depending on the origin of the nucleus on which the encrustation occurs. Dessicated blood clots, ectopic teeth ...

The present study was undertaken to assess the accuracy, precision and validity of hydrophilic Vinyl Poly Siloxane [VPS] impression material for bite mark documentation and analysis. Medium body VPS impressions of maxillary and mandibular anterior teeth among thirty subjects were taken and dental stone casts prepared. Hollow volume overlays were made and metric analysis was done using advanced ...

Background and Aim: Disinfection of dental impression materials can alter their dimensional stability, which in turn can affect the accuracy of dental casts. This study aimed to determine the effect of three disinfectants on the dimensional changes of ir-reversible hydrocolloid impression materials and addition silicones. Materials and Methods: Forty alginate and 40 addition silicone impressio...
