An update on CAD-CAM usage for removable partial denture fabrication: A systematic review.

The accuracy of Computer-Aided Design and Computer-Aided Manufacturing (CAD-CAM) systems in the fabrication of removable partial denture (RPD) frameworks compared to conventional manufacturing methods is of interest to dentists. Known data show that CAD-CAM systems produce RPD frameworks with superior fit and adaptation, potentially reducing post-insertion adjustments and enhancing patient satisfaction. The importance of digital impressions, advanced CAD software and the capabilities of milling or 3D printing equipment in determining the success of CAD-CAM fabricated frameworks is highlighted.

Synthesis and in vitro antifungal efficacy of Cu-chitosan nanoparticles against pathogenic fungi of tomato.

Cu-chitosan nanoparticles were synthesized and evaluated for their growth promotory and antifungal efficacy in tomato (Solanum lycopersicum Mill). Physico-chemical characterization of the developed Cu-chitosan nanoparticles was carried out by DLS, FTIR, TEM, SEM-EDS and AAS. The study highlighted the stability and porous nature of Cu-chitosan nanoparticles.

Maintenance tocolysis with oral micronized progesterone for prevention of preterm birth after arrested preterm labor.

Objective: To evaluate the efficacy of maintenance therapy with oral micronized progesterone (OMP) for prolongation of pregnancy in cases of arrested preterm labor.

Methods: Ninety women at 24-34weeks of singleton pregnancy with intact membranes and arrested preterm labor were randomly allocated to receive OMP (n=45) or placebo (n=45) daily until 37weeks or delivery, whichever was earlier. Outcome parameters were compared using Student t test, χ(2) test, Fisher exact test, and log-rank χ(2) test.
