Children with OI and dentinogenesis imperfecta need the same basic care as discussed in Part 1, but they also need to be monitored for cracking, chipping and abrasion of the teeth. Special care will be needed even with the baby teeth. All of the teeth may not be affected by DI, and primary teeth usually are affected to a greater extent than the permanent teeth. Restorative treatment may be needed at some point. Continue reading →
Bleaching is a procedure which involves lightening of the colour of a tooth through the application of a chemical agent to oxidize the organic pigmentation in the tooth.
Tooth bleaching today is based upon hydrogen peroxide as an active agent. Hydrogen peroxide may be applied directly or produced in a chemical reaction from sodium perborate or carbamide peroxide. Hydrogen peroxide acts as a strong oxidizing agent through the formation of free radicals, reactive oxygen molecules and hydrogen peroxide anions. These reactive molecules attack the long chained, dark coloured chromophore molecules and split them into smaller, less coloured and more diffusible molecules.
What is carbamide peroxide in teeth whitening gels
Carbamide peroxide is also known as urea peroxide or urea hydrogen peroxide. Like any other peroxides, they are oxidizing agents which releases oxygen when in contact with water. The chemical formula is CH6N2O3, or CH4N2O.H2O2.
The carbamide peroxide is a skin, eye and respiratory irritant. It is also corrosive and causes burns. It does not cause injuries at 10% concentration but it might at 35% concentration hence causing white chemical burns on the skin and gums alike. Continue reading →
