Products for lightening teeth are appearing on the market with ever-increasing frequency. Heavy advertising, coupled with heightened public awareness and expectations of an aesthetically pleasing smile, have resulted in increased patient demand for treatment to improve all types of tooth discoloration. Although it is the role of the dental profession to provide the services demanded by the consumer, it is also our duty to be discerning and to re-assess continually the techniques we use, for both efficacy and safety. To do this, long-term follow up of clinical techniques is essential. This paper contains the clinical results of teeth treated over 4.5 years using the hydrochloric acid/pumice microabrasion technique to remove enamel opacities and pigmentation. The subject under discussion is that of enamel discoloration: intrinsic staining with its origins in dentine, such as that caused by the ingestion of tetracycline antibiotics during odontogenesis, is not amenable to this form of surface treatment.
牙齿美白产品在市场上出现的频率越来越高。大量的广告宣传，再加上公众对美观笑容的意识和期望不断提高，导致患者对改善各种牙齿变色治疗的需求增加。虽然满足消费者需求是牙科行业的职责，但我们也有责任保持敏锐，不断重新评估我们所使用的技术，包括疗效和安全性。为此，对临床技术进行长期随访至关重要。本文包含了使用盐酸/浮石微磨除技术治疗牙齿超过4.5年以去除牙釉质不透明和色素沉着的临床结果。正在讨论的主题是牙釉质变色：起源于牙本质的内源性染色，例如在牙齿发育期间因摄入四环素类抗生素引起的染色，不适合这种表面处理形式。
