Clinical Evaluation of Toothbrushes for Elderly Patients: A Crossover Study.

Objectives: The aim of this study was to evaluate the efficacy of 2 newly designed toothbrushes used by elderly individuals based on plaque removal and gingival inflammation reduction compared with 2 commercially available toothbrushes.

Materials And Methods: This was a randomised, controlled, single-blind, 4-period crossover clinical trial. Thirty elderly participants meeting the inclusion criteria were randomly allocated into 4 groups, which determined the sequence of the 4 toothbrushes: CUdent/extra soft, CUdent/soft, GoodAge, and Colgate.

The synthesis and characterization of a novel potassium chloride-fluoridated hydroxyapatite varnish for treating dentin hypersensitivity.

Dentin hypersensitivity is treated using materials that occlude the dentinal tubules or release potassium ions that induce nerve desensitization. In this study we formulated a novel varnish containing potassium chloride and fluoridated hydroxyapatite and evaluated its physical properties and cytotoxicity. Potassium ion release from the varnish was measured.

A novel glass ionomer cement containing MgCO(3 )apatite induced the increased proliferation and differentiation of human pulp cells in vitro.

This study aimed to investigate the in vitro biological response of human dental pulp cells to glass ionomer cement (GIC, Fuji IX GP(®)) containing 2.5% magnesium carbonate apatite (MgCO(3)Ap). MgCO(3)Ap was synthesized by wet method and characterized using FT-IR, XPS, and SEM.
