Conditioning of PEEK Implant Abutment Surfaces Using Photodynamic Therapy, Nd:YAG Laser, and Conventional Methods to Evaluate Shear Bond Strength.

This study was done to evaluate shear bond strength (SBS) and modes of failures after different surface treatment modalities on polyetheretherketone (PEEK) implant abutments. Seventy-five PEEK implant abutment specimens were randomly distributed into five groups based on surface treatment methods: Group I: No treatment, Group II: methylene blue-mediated photodynamic therapy (MB-PDT), Group III: neodymium-doped yttrium aluminum garnet (Nd:YAG) laser, Group IV: Sulfuric acid (HSO), and Group V: Sandblasting (Sb). The measurements for SBS and failure modes for PEEK implant abutment specimens were evaluated via Universal Testing Machine and Stereomicroscope, respectively.

Efficacy of antimicrobial photodynamic therapy in disinfection of Candida biofilms on acrylic dentures: A systematic review.

Background: The aim of this systematic review was to critically analyze and summarize the currently available scientific evidence concerning antifungal efficacy of aPDT against Candida on acrylic surface.

Methods: The focused question was: '"Is aPDT effective in minimizing the counts of Candida on acrylic dentures". A literature search was conducted interpedently on the following electronic research databases: PubMED/MEDLINE, Cochrane, Google Scholar and Embase.

Decontamination of a siloxane impression material by using 5-aminolevulinic acid activated by photodynamic therapy, microwave irradiation, and hydrogen peroxide.

Aim: The present study was intended to evaluate the antimicrobial effect of PDT, HO and MI on the contact angle, strain-in-compression, and tear strength of siloxane impression material formerly colonized with E. coli, S.aureus and S.

Clinical peri-implant parameters and inflammatory cytokine profile among smokers of cigarette, e-cigarette, and waterpipe.

Background: To date, there has been no study identified that assessed peri-implant parameters and local levels of proinflammatory cytokines between waterpipe smokers (WS) and electronic cigarette users (VS). To evaluate the true effect of the risk indicator (WS and VS), a positive control (cigarette smokers [CS]) was added in the study design.

Purpose: To compare clinical and radiographic peri-implant parameters and proinflammatory cytokine profile in the peri-implant sulcular fluid (PISF) among CS, WS, VS, and nonsmokers (NS).

Influence of silane and heated silane on the bond strength of lithium disilicate ceramics - An in vitro study.

Objectives: To evaluate the effect of silane application and silane heat treatment on lithium-disilicate ceramic when bonded to composite resin.

Methods: Twelve blocks of lithium-disilicate (LD) ceramic were fabricated and bonding surfaces were etched using 9.5% hydrofluoric acid (90 seconds).
