Tooth Discoloration and Bleaching
نویسنده
چکیده
Bacterial, mechanical, or chemical irritation to the pulp may result in tissue necrosis and release of disintegration by-products that may penetrate tubules and discolor the surrounding dentin. The degree of discoloration is directly related to how long the pulp has been necrotic. The longer the discoloration compounds are present in the pulp chamber, the greater the discoloration. Such discoloration can usually be bleached intracoronally (Figures 16-1 and 16-2).
