项目摘要
An artificial root canal was prepared using the crown of human incisors filled with phosphate buffer solution. This research was to clarify the effects of peroxide on teeth after the tooth-whitener-application. Tooth-whitener containing 30% hydrogen peroxide or 35% carbamide peroxide was applied according to the instructions with or without acid-etching pretreatment. Luminol-chemi luminescence was used to measure the quantity of peroxide that penetrated into the buffer within the root canal.As a result of we used high density hydrogen peroxide water for the humans tooth crown of a tooth part which we gave the artificial root canal which we devised to and bleached it, and having operated it, a large quantity of hydrogen peroxides were measured between root canals. We mean that this passes the enamel that a hydrogen peroxide is a makeup of a tooth, dentin by bleaching operation and seeped.We observe a change of morphology of a minute organization by observation of a percent section of a tooth after bleaching.I recognize some changes, but there is not it in the situation that I can conclude to be it yet. However, a large quantity of dissolution of a dentin ingredient was recognized in immersion of a tooth to the hydrogen peroxide water. A makeup of dentin dissolves by bleaching, and this thing suggests the possibility that, meanwhile, I go through a chance, and a bleach arrives at to a pulp cavity, a root canal.
采用人门牙冠填充磷酸盐缓冲液制备人工根管。本研究旨在阐明过氧化氢在牙齿美白后对牙齿的影响。按说明书使用含30%过氧化氢或35%过氧化脲的牙齿增白剂,有或没有酸蚀预处理。用鲁米诺化学发光法测量过氧化物渗透到根管内缓冲液中的量。由于我们使用了高密度过氧化氢水用于人类牙冠的一部分我们给了人工根管我们设计并漂白了它,在操作它之后,在根管之间测量了大量的过氧化氢。我们的意思是这一过牙釉质即过氧化氢是构成牙齿的一种物质,牙本质通过漂白操作而渗出。我们通过观察牙齿漂白后的百分之一的部分,观察到一分钟组织形态的变化。我认识到一些变化,但目前的情况还不能让我得出结论。然而,当牙齿浸泡在过氧化氢水中时,牙本质成分会大量溶解。牙本质的组成通过漂白而溶解,这件事表明,与此同时,我经历了一个机会,漂白剂到达了牙髓腔,根管。
