Physicochemical characterization of a dental eggshell powder abrasive material.

Background: This study aimed to determine the physicochemical characteristics of an eggshell-based dental abrasive material.

Methods: The eggshell powder abrasive material (EPAM) was synthesized by ball milling eggshell powder and surfactants. Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), transmission electron microscopy (TEM) and a laser diffraction particle size analyzer (PSA) were used to characterize EPAM.

Reducing the surface roughness of dental acrylic resins by using an eggshell abrasive material.

Statement Of Problem: Excessive surface roughness of denture base resins adversely impacts oral health.

Purpose: The purpose of this in vitro study was to examine the abrasive potential of eggshell powder in reducing the surface roughness of denture base resins.

Material And Methods: Thirty poly(methyl methacrylate) specimens were fabricated and polished with eggshell powders of different particle sizes and with pumice.

Failure investigation of soldered stainless steel orthodontic appliances exposed to artificial saliva.

Unlabelled: Globally in the field of Dental Technology, soldering continues to be the prevailing joining technique for removable orthodontic appliances. The strength of the soldered joint, however, is a growing concern to dental technicians since the commonly employed silver solder undergoes accelerated corrosion and ultimately influences the success of orthodontic appliances intraorally.

Objective: The goal of this in vitro study was to determine the effects of exposure to artificial saliva on the mechanical strength of orthodontic silver-soldered stainless steel joints.
