The conservative technique for bleaching vital teeth using a nightguard and a 10% carbamide peroxide solution has captured the esthetic interests of the dental profession. The purpose of this article is to assess the safety of the products used in this bleaching teclmiqtie based on resitltsfrom past related research and current research. Ten percent carbamide peroxide solutiotis used in numerous studies have demonstrated tissue-healing properties as well as a propensity for the reduction of plaque and gingivitis. None of these clinical studies revealed any untoward or detrimental side effects, and all demonstrated beneficial effects. Although some concern exisis regarding the potentiating effects of peroxide solutions in the presence of known carcinogens, concerns of toxicity or damage to hard and soft tissues appear utifounded. The majority of current and past research and literature itulicates that the current use of a 10% carbamide peroxide solution in the tnethod advocated for bleachitig vital teeth is apparently safe when administered properly under the sttpervision ofa dentist.
