Comparative Evaluation of Digital and Conventional Workflows for the Fabrication of Multi-Unit Implant-Supported Fixed Restorations: An Empty Review.

This study aimed to do a comprehensive systematic review on the comparison of digital and conventional workflows regarding prosthetic outcomes, accuracy of implant impressions, framework passivity and fit, and clinical fabrication of multi-unit implant-supported fixed restorations. The EMBASE, PubMed, Scopus, and Cochrane Library databases were searched for relevant articles published up until April 2020. No in-vivo article was found to compare full digital and conventional workflows regarding the accuracy of implant impressions, passivity and fit of frameworks, and prosthetic outcomes.

Effect of Repeated Use of Different Types of Scan Bodies on Transfer Accuracy of Implant Position.

Statement Of The Problem: Some components of implant treatment are reusable. Therefore, possible changes during fixation, removal, and sterilization process should be tested. Many studies have examined the reuse of implant parts, but the impact of repeated use of scan bodies on the accuracy of implant position has not been well investigated.

Fully Digital versus Conventional Workflows for Fabricating Posterior Three-Unit Implant-Supported Reconstructions: A Prospective Crossover Clinical Trial.

This study assessed the clinical variables influencing the success of three-unit implant-supported fixed dental prostheses (ISFDPs) fabricated using either fully digital or conventional workflows. The clinical trial evaluated 10 patients requiring three-unit ISFDPs in the posterior mandible. Maxillomandibular relation records, and digital and conventional impressions were obtained from each patient using an intraoral scanner (IoS) and polyvinylsiloxane (PVS), and the frameworks were fabricated using zirconia and cobalt-chromium, respectively.

Quercetin Decreases Th17 Production by Down-Regulation of MAPK- TLR4 Signaling Pathway on T Cells in Dental Pulpitis.

Statement Of The Problem: Quercetin is a pharmacological flavonoid that can inhibit high mobility group box1 (HMGB1) protein, a non-histone nuclear protein that is implicated in inflammation. Th17 cells are important cells in the pathogenesis of inflammation. Pulpitis is the inflammation of dental pulp, which usually is accompanied by pain.

Activation Toll-Like Receptor7 (TLR7) Responsiveness Associated with Mitogen- Activated Protein Kinase (MAPK) Activation in HIOEC Cell Line of Oral Squamous Cell Carcinoma.

Statement Of The Problem: Oral squamous cell carcinoma is the most common oral malignancy. Toll-like receptor (TLR) activation led to alterations in the levels of mRNA encoding the TLR accountable for recognizing the inducing agonist and cross-regulation of other TLR.

Purpose: The purpose of this study is determination of mitogen-associated protein kinase (MAPK) activation in human immortalized oral epithelial cell (HIOEC) line via up regulating of TLR7.

Effect of low-concentration povidone iodine on postoperative complications after third molar surgery: a pilot split-mouth study.

Purpose: Povidone iodine is used primarily as an antiseptic to decrease surgical site infection. Its hemostatic and antiedematous properties in oral surgery also have been investigated recently.

Patients And Methods: A randomized controlled clinical trial was performed in 30 patients undergoing mandibular third molar removal in a split-mouth design.
