1. Glass Ionomer Cements with Improved Bioactive and Antibacterial Properties
Abstract : Dental restorative cements are placed in a harsh oral environment where they are subjected to thermal shock, chemical degradation, and repeating masticatory force. The ideal restorative dental cements should have superior mechanical properties, chemical stability, aesthetic, good handling properties, biocompatibility, antibacterial properties, and preferably bioactivity.

2. Clinical aspects of restorative treatment in the primary dentition
Abstract : The failure rate of restorative treatment in primary teeth was studied in a cohort of children born in 1981 and related to caries diagnosis, prevalence and distribution on different tooth surfaces, and compared with a cohort of children born in 1971. Concurrently, the longevity of composite resin in modified Class 2 cavities in primary molars was followed up and the resistance of deciduous and permanent enamel to acid adjacent to composite resin and glass polyalkeonate cement (GPA) was tested in vitro.

3. Calcium aluminate cement as dental restorative : Mechanical properties and clinical durability
Abstract : In 1995, the Swedish government recommended the discontinuation of amalgam as restorative in paediatric dentistry. Because the mercury content in amalgam constitutes an environmental hazard, its use has declined. READ MORE

4. Influence of a dental ceramic and a calcium aluminate cement on dental biofilm formation and gingival inflammatory response
Abstract : Dental restorative materials interact with their surrounding oral environment. Interaction factors can be release of toxic components and/or effects on biofilm formation and gingiva. In the end of the nineties, a calcium aluminate cement (CAC) was manufactured as a “bioceramic” alternative to resin composite. READ MORE

5. 2-hydroxyethylmethacrylate: Effects on the immune system in mice
Abstract : The use of acrylic compounds in dentistry has increased. Different derivatives of acrylic acid are used in dental bonding material, in resins and in glass ionomer cements. While there have been only a few reports on adverse reactions in patients, there is substantial evidence of adverse reactions in dental personnel. READ MORE
