This review of different bleaching agents used for internal bleaching of endodontically treated discoloured teeth included 8 studies. While the findings suggest all agents had a positive effect the quality of the avaiiable studies is low so the findings should be interpreted cautiously.

This review of difference concentrations of hydrogen peroxide for in-office dental bleaching on colour change and bleaching sensitivity included 25 RCTs. The findings indicate that low and medium hydrogen peroxide concentrations had lower risk and intensity of bleaching sensitivity and no difference in colour change efficacy compared with high concentrations.

This review of the effect of light activation on tooth whitening efficacy included 21 RCTs finding that neither the efficacy nor the risk of tooth sensitivity of in-office bleaching was influenced by the use of light, regardless of the hydrogen peroxide concentration.

Ten studies involving a total of 394 patients were included in this review of desensitising agents during tooth bleaching. While the results suggest a reduction in sensitivity variation in the concentration of the agents used, the quality of the included studies means the results should be interpreted with caution.

Dental fluorosis is characterised by bilateral, diffuse, thin and horizontal white striations and stained plaque areas, with pitting and discolouration of the enamel in more severe case. It is caused by excess fluoride ingestion during tooth development and can have an impact on quality of life. The aim of this study was to evaluate the [read the full story…]
Tooth whitening is an increasingly popular cosmetic treatment. In surgery bleaching and dentist-prescribed, home-applied bleaching are the two most common procedures. Light activation using a range of light sources, halogen curing lights, xenon–halogen lights, plasma arcs, light emitting diodes (LEDs), LED plus lasers, and lasers have been used to reduce the bleaching time and decrease [read the full story…]
