Dental Caries is a kind of chronic oral disease that greatly threaten human being’s health. Though dentists and researchers struggled for decades to combat this oral disease, the incidence and prevalence of dental caries remain quite high. Therefore, improving the disease management is a key issue for the whole population and life cycle management of dental caries. So clinical difficulty assessment system of caries prevention and management is established based on dental caries diagnosis and classification. Dentists should perform oral examination and establish dental records at each visit. When treatment plan is made on the base of caries risk assessment and carious lesion activity, we need to work out patient‑centered and personalized treatment planning to regain oral microecological balance, to control caries progression and to restore the structure and function of the carious teeth. And the follow-up visits are made based on personalized caries management. This expert consensus mainly discusses caries risk assessment, caries treatment difficulty assessment and dental caries treatment plan, which are the most important parts of caries management in the whole life cycle.

龋齿是一种严重威胁人类健康的慢性口腔疾病。尽管牙医和研究人员几十年来一直在努力对抗这种口腔疾病，但龋齿的发病率和患病率仍然很高。因此，改善疾病管理是龋齿全人群和全生命周期管理的关键问题。因此，建立了以龋齿诊断和分类为基础的龋齿防治临床难度评估体系。牙医应在每次就诊时进行口腔检查并建立牙科记录。在根据龋齿风险评估和龋损活动度制定治疗方案时，需要制定以患者为中心的个性化治疗方案，恢复口腔微生态平衡，控制龋齿进展并恢复龋齿的结构和功能。并根据个性化龋齿管理进行随访。本专家共识主要讨论龋齿风险评估、龋齿治疗难度评估和龋齿治疗方案，是龋齿全生命周期管理中最重要的部分。
