The oral specialist diagnosis and treatment has the characteristics of diagnosis and treatment behavior immediacy, phased diagnosis and treatment process, diagnosis and treatment population diversity, diagnosis and treatment effect subjectivity, and patient dominance of outpatient medical record storage. In the process of fulfilling the notification obligation, there may be risks such as the protection of the autonomous rights and interests of minor patients, the limited communication time, the insufficient clarity of the first diagnosis plan, the new requirements for the performance form, and the expansion of the application of the presumption of fault. The oral specialist diagnosis should pay attention to the true expression of the informed object; the diversification of the informative channels to obtain the clear attitude of the patient; the optimization of the informative process to make up for the information imbalance; the strict implementation of the core medical safety system to promote the actual fulfillment of the notification obligation.
