A large number of the all operative work performed in a dental office is amalgam fillings. Secondary caries continuous to be a serious problem although amalgam has been improved to a large extent. All efforts that have been made to eliminate the problem of secondary caries associated with amalgam fillings have not been very successful so far. There is always a lack of permanent seal between restorations and the prepared tooth surfaces so that microleakage always exists. The purpose of this paper was to search the literature on the subject and find ways and attempts that have been made on the elimination of secondary caries. On the other hand was aimed to present and discuss the application of fluorides into the cavity preparation as a preventive method of eliminating secondary caries as well as the possible effects of fluorides on the dental pulp if they exist. The literature gives a lot of information on the subject and fluorides in the cavity before the filling insertion seems to be a safe and approved method against secondary caries. Regarding the effect of fluorides on the pulp it is indicated that when the proper agent and technique is used there is no any deleterious effect and the method is not contraindicated.
牙科诊所进行的大量手术操作都是汞合金补牙。尽管汞合金已在很大程度上得到改进，但继发龋仍然是一个严重问题。迄今为止，为消除与汞合金补牙相关的继发龋问题所做的一切努力都不太成功。修复体与预备好的牙面之间始终缺乏永久性密封，因此微渗漏一直存在。本文的目的是检索关于该主题的文献，找出为消除继发龋所做的方法和尝试。另一方面，旨在介绍和讨论在窝洞预备中应用氟化物作为消除继发龋的预防方法，以及氟化物对牙髓可能存在的影响。文献提供了关于该主题的大量信息，在充填前将氟化物置于窝洞内似乎是一种安全且被认可的预防继发龋的方法。关于氟化物对牙髓的影响，表明当使用合适的制剂和技术时，不会有任何有害影响，且该方法并非禁忌。
