Is dental erosive wear a common condition among 16-year-olds in Troms, Norway?

The aim of the present study was to investigate the prevalence, distribution and severity of dental erosive wear among 16-year old adolescents living in Troms. Clinical, intra-oral pictures of 392 individuals involved in the «Tromsø undersøkelsen, Fit Futures» were evaluated for dental erosive wear by three previously calibrated examiners.

Water sorption and solubility of polyamide denture base materials

Some patients experience adverse reactions to poly(methyl methacrylate)-based (PMMA) dentures. Polyamide (PA) as an alternative to PMMA has, however, not been well documented with regard to water sorption and water solubility. The aim of this in vitro study was to measure water sorption and water solubility of two PA materials compared with PMMA, and to evaluate the major components released from the PA materials and the effect on hardness of the materials.
