Discolouration of teeth, especially the anteriores, can result in considerably cosmetic impairment in person. Combine effects of intrinsic and extrinsic colour determines the appearance of teeth. Whitening of teeth with bleaching is a more conservative therapeutic method than full crowns, veneers or composite restorations which is more invasive and expensive. Among bleaching techniques, in office bleaching with carbamide peroxide provide superior aesthetic result in short period of time with no adverse effects. This paper presents case series of tooth discolouration in non-vital tooth which was successfully bleached using 35 % carbamide peroxide. After 1 year follow up the prognosis was good with no reversal of tooth discolouration. This case report allows the better understanding of the concept of nonvital tooth bleaching with carbamide peroxide which gives a non-invasive alternative for aesthetic purpose in preserving the natural tooth structure.
牙齿变色,尤其是前牙变色,会给患者带来相当大的美容问题。牙齿的内在和外在颜色综合作用决定了牙齿的外观。与全冠、贴面或复合修复相比,牙齿漂白是一种更保守的治疗方法,后几种方法侵入性更强且费用更高。在漂白技术中,使用过氧化脲进行诊室漂白能在短时间内提供更好的美学效果且无不良反应。本文介绍了一组非活髓牙牙齿变色病例,这些病例使用35%的过氧化脲成功进行了漂白。经过1年的随访,预后良好,牙齿没有出现变色逆转。本病例报告有助于更好地理解使用过氧化脲进行非活髓牙漂白的概念,它为出于美学目的保留天然牙齿结构提供了一种非侵入性的替代方法。
