Serine/Glycine Lipid Recovery in Lipid Extracts From Healthy and Diseased Dental Samples: Relationship to Chronic Periodontitis.

Toll-like receptor 2 (TLR2) activation has been implicated in the pathogenesis of periodontal disease but the identity of the TLR2 agonists has been an evolving story. The serine/glycine lipids produced by are reported to engage human TLR2 and will promote the production of potent pro-inflammatory cytokines. This investigation compared the recovery of serine/glycine lipids in periodontal organisms, teeth, subgingival calculus, subgingival plaque, and gingival tissues, either from healthy sites or periodontally diseased sites.

Should Healing Abutments and Cover Screws for Dental Implants be Reused? A Systematic Review.

Purpose: To systematically review the current scientific evidence to assess if healing abutments and cover screws for dental implants can be resterilized effectively for reuse. A secondary purpose was to investigate if there has been any reported adverse biological or mechanical consequences to implants, or harm to patients with the reuse of healing abutments or cover screws.

Materials And Methods: An electronic search of the English language scientific literature was performed independently by multiple investigators using a systematic search process using the PubMed search engine and Cochrane database.
