In Vivo Assessment of Trimetaphosphate Nanocomposite-Based Polyamide-6 Scaffolds Enhanced With Silver Nanoparticles for Bone Regeneration.

The aim of this study was to evaluate the influence of nanocomposite materials, specifically sodium trimetaphosphate (TMP) nanoparticles decorated with 2.5% silver nanoparticles (AgNP), incorporated into polyamide-6 (Pa6) polymeric matrices on bone repair in surgically created critical-size defects in rat calvaria. Eighteen male Wistar rats were divided into three groups based on the treatment received: control group (C)-blood clot; Pa6-AgNP; and Pa6-TMP-AgNP.

Exploring the potential of rapid maxillary expansion and masticatory muscle activity in unilateral posterior crossbite.

Background: This systematic review and meta-analysis aimed to evaluate if rapid maxillary expansion improves the activity of the masticatory muscles (masseter and temporal) in patients with unilateral posterior crossbite.

Material And Methods: Searches were performed in PubMed/MEDLINE, Scopus, Web of Science, Embase, Cochrane Library, and grey literature. A manual search of orthodontic journals was also performed.

Does oral lichen planus aggravate the state of periodontal disease? A systematic review and meta-analysis.

Background: The objective of this systematic review and meta-analysis (SRM) was to assess the evidence between the association of oral lichen planus and periodontal disease, evaluating the periodontal clinical parameters and biomarkers levels.

Methods: This systematic review and meta-analysis followed PRISMA and was registered in PROSPERO (CRD42020181513). Searches were accomplished in databases for articles published until June 2021.
