The aim of this work is a review of recent scientific literature about intra-oral halitosis among patients using dentures. Halitosis is a condition in which an unpleasant smell comes out of the oral cavity, which is caused mainly by volatile sulfur and non-sulfured compounds. The etiology of halitosis may be intra- or extra-oral; in most patients, however, it is due to the activity of microorganisms in the oral cavity. The problem of the occurrence of intra-oral halitosis has accompanied patients for many years. In dental prosthetics, the problem of halitosis occurs in patients using removable or fixed dentures. In both cases, new niches for the development of microorganisms may be created, including those related to intra-oral halitosis. It should be noted that dentures-both fixed and removable-are a foreign body placed in the patient's oral cavity which, in case of insufficient hygiene, may constitute a reservoir of microorganisms, causing this unpleasant condition. Conventional treatment of intraoral halitosis reduces microbial activity via chemical and/or mechanical action. Currently, the search for new strategies in the treatment of halitosis is in progress. One idea is to use photodynamic therapy, while another is to modify poly(methyl methacrylate) (PMMA) with silver and graphene nanoparticles. Additionally, attempts have been made to combine those two methods. Another unconventional method of treating halitosis is the use of probiotics.
这项工作的目的是回顾近期关于佩戴假牙患者口腔内口臭的科学文献。口臭是一种口腔散发出难闻气味的状况，主要由挥发性硫化合物和非硫化合物引起。口臭的病因可能在口腔内或口腔外；然而，在大多数患者中，这是由于口腔内微生物的活动所致。口腔内口臭的问题多年来一直困扰着患者。在牙科修复领域，佩戴可摘义齿或固定义齿的患者都会出现口臭问题。在这两种情况下，都可能为微生物的滋生创造新的环境，包括与口腔内口臭相关的环境。应当注意的是，固定义齿和可摘义齿都是放置在患者口腔内的异物，如果卫生措施不到位，可能会成为微生物的滋生地，导致这种令人不适的状况。传统的口腔内口臭治疗方法通过化学和/或机械作用降低微生物活性。目前，治疗口臭的新策略研究正在进行中。一种想法是使用光动力疗法，另一种是用银和石墨烯纳米颗粒对聚甲基丙烯酸甲酯（PMMA）进行改性。此外，人们还尝试将这两种方法结合起来。另一种治疗口臭的非传统方法是使用益生菌。
