Det er kommet spørsmål fra en tannlege som er bekymret over manglende informasjon om innholdet av ulike mulig helseskadelige stoffer i fluor skyllevæske og tannkremer. Dette er et betimelig spørsmål.

Previously, we have reported data obtained from near-infrared reflection spectroscopy (NIRS) used to non-invasively monitor tissue changes after optical exposure. The results indicated that oral mucosa may be more sensitive than skin to blue light. In this pilot study, visible data from NIRS (VNIRS) was used to observe differences between exposure groups with respect to the following parameters: pigmentation (melanin index; MI), blood oxygenation (OX) and erythema (erythema index; EI).

Six commonly used composite resin materials and recommended bonding systems were tested to assess shear bond strength at the interface between aged and new composites with and without bonding. Test specimens were aged in water for 60 d before new composite was placed.

Three bifunctional silane coupling agent monomers and their blends with a cross-linking silane were investigated as six experimental adhesion-promoters in vitro. Three organosilane monomers, 3-methacryloxypropyltrimethoxysilane, styrylethyltrimethoxysilane, and 3-(N-allylamino)propyltrimethoxysilane, were prepared as 1% (v/v) primers and also blended with a cross-linking silane, 1,2-bis-(triethoxysilyl)ethane at 0.5% (v/v), in a 95:5 solution of ethanol in deionized water.

Sammanfattning Titan och titanlegeringar använda i odontologiska sammanhang karaktäriseras av god biokompatibilitet. Detta är väl dokumenterat i laboratorieförsök med celler i kultur, djurförsök och kliniska studier på människa, och förklaras med att alla titanytor är täckta av ett mycket tunt och stabilt oxidskikt. Detta kan ytterligare förbättras med olika former av mekanisk eller kemisk behandling av […]
