Outcomes of modified arthrocentesis using concentric needle and cannula technique with sequential viscosupplementation and orthobiologics in both TMJ compartments.

Minimally invasive therapeutic procedures have been applied for the management of degenerative joint disease in the temporomandibular joint (TMJ). This study describes a modified technique of arthrocentesis with concentric needle and cannula in the TMJ associated with viscosupplementation and/or orthobiologics. Its effects were evaluated based on clinical outcomes related to pain, mouth opening, and joint sound, along with longitudinal tomographic evaluation based on the Wilkes classification.

Alternative to Avoid Tooth Discoloration after Regenerative Endodontic Procedure: A Systematic Review.

This systematic review aimed to evaluate whether alternative materials to conventional triple antibiotic paste (TAP - metronidazole, ciprofloxacin, and minocycline) and grey mineral trioxide aggregate (GMTA) could avoid tooth discoloration in teeth submitted to Regenerative Endodontic Procedure (REP). It was also investigated if dental bleaching is able to reverse the color of darkened teeth due to REP. The search was conducted in four databases (Medline via PubMed, Scopus, ISI Web of Science and BVS - Virtual health library), following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses.

Association between obstructive sleep apnea and alcohol, caffeine and tobacco: A meta-analysis.

The aim of this systematic review was to answer the focused question, "Is there an association between obstructive sleep apnea (OSA) and alcohol, caffeine or tobacco use?" Five electronic databases (Cinahl, Literatura Latth American and Caribbean, PubMed, Scopus, Web of Science) and 3 grey literature (Google Acadêmico, ProQuest, OpenGrey) were searched, as well as search on reference list of included papers and contacts with study authors. Observational studies were included. The Meta-Analysis of Statistics Assessment and Review Instrument (MAStARI) tool assessed the potential risk of bias (RoB) among the studies, while the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach determined the level of evidence.

Effect of Milk Renewal on Cell Viability In Vitro at Different Time Frames.

The purpose of this study was to evaluate if the renewal of milk as a storage medium, every 12, 24 and 48 h, is able to increase its ability to maintain human periodontal ligament fibroblasts (PDLF) viability over time. PDLF were soaked in Minimum Essential Medium at 37 °C (MEM-37) (positive control), tap water (Water) (negative control) and in skimmed milk (44 wells) at 5 °C and 20 °C. The skimmed milk was renewed every 12 h (Milk-12), 24 h (Milk-24) and 48 h (Milk-48) in 11 wells of each plate, and the milk in the remaining 11 wells of each plate was maintained in situ (not renewed milk) (NRM).
