Comparison of Chlorhexidine Gluconate, Sodium Hypochlorite, Neem Extract, and Microwave Radiation for Disinfection of Type IV Dental Stone.

Objective:  The present study evaluated the effect of chemical disinfectants and microwave sterilization on the removal of biofilm containing , , and from type IV dental stone.

Materials And Methods:  One hundred twenty-eight ( = 128) type IV dental cast stone specimens were prepared, and biofilms of microorganisms were cultured. Dental stone samples were subjected to disinfection protocols, including 0.

Comparison of surface micro-roughness and adaptation of titanium and cobalt chrome implant abutment fabricated by selective laser melting and conventional techniques.

Purpose: The objective of this study was to assess the surface micro-roughness and abutment adaptation of selective laser melting (SLM) implant abutments in comparison to cast and machined implant abutments.

Methods: Forty abutment specimens were divided equally into four groups according to the fabrication technique as follows (n = 10), Machined Ti alloy abutments (Control), Cast CoCr abutments, SLM-CoCr abutments, and SLM-Ti alloy abutments. Forty internal connection implants (Ø 4.

Comparison of misfit and roughness of CAD-CAM ZrO, selective laser sintered CoCr and preformed Ti implant abutment crowns.

Background: Marginal misfit and surface roughness of customized implant abutments is critical for restorative success. However, little is known about the comparison of misfit and surface roughness of CAD-CAM Zirconium oxide (ZrO), selective laser melting (SLM) Cobalt Chrome (CoCr) and preformed abutments. The aim of the study is to investigate the relation of misfit and micro-roughness of selective laser melting (SLM), preformed and CAD-CAM implant abutments.

Comparison of De-Torque and Failure Load Evaluation of Selective-Laser-Sintered CoCr, CAD-CAM ZrO, and Machined Implant Abutment/Restoration.

Aim: This study aimed to compare the torque loss, fracture load, compressive strength, and failure types of selective-laser-sintered cobalt chromium (SLM-Co-Cr), computer-aided design and computer-aided manufacturing zirconium oxide (CAD-CAM-ZrO), and machined titanium (Ti) implant abutments.

Methods: Thirty endosseous dental implants were vertically embedded with machined Ti (control group), CAD-CAM-ZrO, and SLM-Co-Cr abutments. Abutment fabrication involved CAD-CAM milling and SLM technology.

The efficacy of iatrosedation and music listening techniques in attenuating dental anxiety in patients undergoing dental crown preparation: A randomized clinical trial.

Dental anxiety is a common problem encountered in dental clinics that affects both patients and dentists. Adequate management of dental anxiety is critical for optimal treatment outcomes for the patient. This study aims to assess the efficacy of two anxiety-reduction techniques (iatrosedation and music listening) for dental crown preparation in adult patients.
