Efficacy and safety evaluation of alcohol-containing and alcohol-free mouth rinses: A clinicocytological study.

Context: Whether the alcohol-based mouth rinses are as good as nonalcoholic mouth rinses as far as oral mucosal safety is concerned?

Aims: The aim of the study was to investigate the oral mucosal safety of widely used alcohol- and nonalcohol-based mouth rinses at their recommended doses.

Settings And Design: The clinical and cytological investigations were carried out by enrolling 120 systemically healthy volunteers fulfilling the inclusion criteria. The volunteers were subjected to a repeated mouth rinse for 60 days to either alcohol-based or alcohol-free mouth rinses at their recommended dosages.

Comparative in vitro SEM study of a novel root canal irrigant-MTAD and conventional root biomodifiers on periodontally involved human teeth.

Background: Smear layer removal and collagen fiber exposure may improve regeneration which can be accomplished by use of root biomodifiers. These enhance the degree of connective tissue attachment to denuded roots. The objective of this in vitro study was to evaluate and compare novel root canal irrigant and other root biomodifiers for smear layer removal on periodontally involved human teeth.

Adhesion and biologic behavior of human periodontal fibroblast cells to resin ionomer Geristore: a comparative analysis.

Aim: The resin ionomer Geristore, originally designed for restorative procedures, has been used extensively in treating subgingival defects (such as root resorption and perforations) and as a retrofilling material. The purpose of this study was to evaluate the cell adhesion as well as in vitro biocompatibility of human periodontal fibroblast cells with resin ionomer Geristore in comparison with mineral trioxide aggregate (MTA) and glass ionomer cement (GIC).

Material And Method: Adhesion, growth, and morphology of human periodontal fibroblasts over test materials were evaluated by scanning electron microscopy (SEM).

Potential of the propolis as storage medium to preserve the viability of cultured human periodontal ligament cells: an in vitro study.

Aim: In vitro experiments were carried out to evaluate the potential of propolis, a natural resin known for its wide therapeutic window, as storage medium to preserve the viability of cultured human periodontal ligament (PDL) cells.

Materials And Methods: Primary cultures of human PDL cells were subjected to either independent exposure of propolis (2.5%, 5.
