Root caries has gained much attention in the last few years. As the world's population is ageing and people currently tend to retain more teeth compared with older generations, there is an increased prevalence of periodontal disease and gingival recession, which may accelerate the onset of root caries.
This review aims to summarise recent findings related to the diagnosis, prevention and treatment of root caries.
MEDLINE (OVID) and Scopus (Elsevier) searches were performed to identify and discuss articles that address the pathogenicity and clinical management of root caries.
Root caries is a multifactorial disease. Cariogenic species involved in root caries are less dependent on carbohydrates since collagen degradation inside the dentinal tubules can provide nutrients and microcavities for the invading microorganisms. Furthermore, the root surface has fewer minerals in comparison with enamel, which may accelerate the onset of demineralisation. Root caries could be prevented by patient education, modification of risk factors, and the use of in-office and home remineralisation tools. The use of non-invasive approaches to control root caries is recommended, as the survival rate of root caries restorations is poor. When plaque control is impossible and a deep/large cavity is present, glass ionomer or resin-based restorations can be placed.
The assessment of root carious lesions is critical to determine the lesion activity and the required intervention. Dental practitioners should also be aware of different prevention and treatment approaches to design optimum oral health care for root caries-affected patients.
近年来，根面龋受到了广泛关注。随着世界人口老龄化以及人们与老一辈相比倾向于保留更多的牙齿，牙周病和牙龈退缩的患病率有所增加，这可能加速根面龋的发生。
本文旨在综述根面龋的诊断、预防和治疗的最新研究进展。
通过 MEDLINE（OVID）和 Scopus（Elsevier）检索，筛选并讨论了与根面龋的致病性和临床管理相关的文章。
根面龋是一种多因素疾病。与根面龋相关的致龋菌对碳水化合物的依赖性较低，因为牙本质小管内的胶原降解可为入侵微生物提供营养物质和微腔。此外，与牙釉质相比，根面的矿物质较少，这可能加速脱矿的发生。通过患者教育、改变危险因素以及使用诊室和家庭再矿化工具，可以预防根面龋。建议采用非侵入性方法来控制根面龋，因为根面龋修复体的存活率较低。当菌斑控制不可能且存在深大龋洞时，可以放置玻璃离子水门汀或树脂基修复体。
评估根面龋损对于确定病变活性和所需干预措施至关重要。牙科医生还应了解不同的预防和治疗方法，为受根面龋影响的患者设计最佳的口腔保健方案。
