In vitro evaluation of human enamel remineralization after treatment with Ginger, Ashwaganda and Maca herbal dentifrices versus commercially available fluoride containing dentifrice.

Background: Compare the remineralization efficiency of Ginger, Ashwaghanda and Maca dentifrices versus commercially fluoride containing dentifrice.

Methods: Ginger, Ashwaghanda and Maca extracts were prepared by solvent extraction methodology and were characterized using transmission electron microscope, dynamic light scattering, and inductively coupled plasma optical emission spectrometer. The pH of the dentifrices was evaluated by pH meter.

Physical and mechanical evaluation of dental resin composite after modification with two different types of Montmorillonite nanoclay.

Objectives: Evaluation of degree of conversion (DC), flexural properties, micro-hardness and color change (ΔE) of dental resin composite after modification with two types of organo-modified Montmorillonite (MMT) nanoclay; an experimentally synthesized polymethyl-methacrylate modified MMT nanoclay (PMMA/MMT), and a commercially available one (Cloisite20A).

Methods: MMT was synthesized by sol-gel technique, organo-modified with polymethyl-methacrylate and characterized using EDX, XRD and FTIR. PMMA/MMT and Cloisite20A nanoclay were added to flowable resin composite in 0.
