CHITOSAN – ANTIBACTERIAL USE IN DENTAL MATERIALS -

Chitosan – Antibacterial use in dental materials Secondary caries is the primary reason for replacement of composite fillings, and clinical studies report more secondary caries when composites are used compared to amalgam in high-risk caries groups. This highlights the need for development of materials that will reduce or inhibit biofilm formation on dental materials. The challenges […]

Newsletter, March 2015 -

We are currently investigating the inhibitory effect of chitosan on biofilm formation The challenges of antibacterial agents in dental materials can be many:• The agent must be present in a concentration that inhibits or reduce biofilm formation.• The concentration must not exceed cytotoxic level.• The aesthetic, mechanical and chemical qualities of the material must not […]

Caries progression on approximal surfaces… -

Caries progression on approximal surfaces in contact with composite restorations   Objective The study aimed to assess risk factors for caries progression on approximal surfaces in contact with newly placed Class II composite resin restorations.   Methods This is a prospective, practice-based study.  From 2001 to 2004, a total of 3286 Class II composite resin […]

In vitro cell responses to 2-hydroxy-propylmethacrylate (HPMA) -

Objectives The objective of the current study was to explore possible cellular responses to the methacrylate monomer 2-hydroxy-propylmethacrylate (HPMA) in vitro. HPMA is one of several methacrylates that are commonly used in resin-based dental materials. However, the toxic response to this monomer is not yet investigated. Methods Different cell cultures were exposed to different concentrations […]
