Expert consensus on digital guided therapy for endodontic diseases / 国际口腔科学杂志·英文版

Digital guided therapy (DGT) has been advocated as a contemporary computer-aided technique for treating endodontic diseases in recent decades. The concept of DGT for endodontic diseases is categorized into static guided endodontics (SGE), necessitating a meticulously designed template, and dynamic guided endodontics (DGE), which utilizes an optical triangulation tracking system. Based on cone-beam computed tomography (CBCT) images superimposed with or without oral scan (OS) data, a virtual template is crafted through software and subsequently translated into a 3-dimensional (3D) printing for SGE, while the system guides the drilling path with a real-time navigation in DGE. DGT was reported to resolve a series of challenging endodontic cases, including teeth with pulp obliteration, teeth with anatomical abnormalities, teeth requiring retreatment, posterior teeth needing endodontic microsurgery, and tooth autotransplantation. Case reports and basic researches all demonstrate that DGT stand as a precise, time-saving, and minimally invasive approach in contrast to conventional freehand method. This expert consensus mainly introduces the case selection, general workflow, evaluation, and impact factor of DGT, which could provide an alternative working strategy in endodontic treatment.

Experts consensus on the procedure of dental operative microscope in endodontics and operative dentistry / 国际口腔科学杂志·英文版

The dental operative microscope has been widely employed in the field of dentistry, particularly in endodontics and operative dentistry, resulting in significant advancements in the effectiveness of root canal therapy, endodontic surgery, and dental restoration. However, the improper use of this microscope continues to be common in clinical settings, primarily due to operators' insufficient understanding and proficiency in both the features and established operating procedures of this equipment. In October 2019, Professor Jingping Liang, Vice Chairman of the Society of Cariology and Endodontology, Chinese Stomatological Association, organized a consensus meeting with Chinese experts in endodontics and operative dentistry. The objective of this meeting was to establish a standard operation procedure for the dental operative microscope. Subsequently, a consensus was reached and officially issued. Over the span of about four years, the content of this consensus has been further developed and improved through practical experience.

The prevention and control of a new coronavirus infection in department of stomatology / 中华口腔医学杂志

During a short period of time, the outbreak of pneumonia caused by a novel coronavirus, named Novel Coronavirus Pneumonia (NCP), was first reported in China, spreading to 24 countries and regions rapidly. The number of confirmed cases and deaths continued to rise. World Health Organization (WHO) announced that the outbreaks of the novel coronavirus have constituted a Public Health Emergency of International Concern. Efficient infection control can prevent the virus from further spreading, which makes the epidemic situation under control. Due to the specialty of oral healthcare settings, the risk of cross infection is severe among patients and oral healthcare practitioners. It's more urgent to implement strict and efficient infection control protocols. This paper, based on existing guidelines and published researches pertinent to dental infection-control principles and practices, mainly discusses epidemiological characteristics of NCP and the features of nosocomial infection in oral healthcare settings, and furthermore provides recommendations on patient's evaluation, and infection control protocols in department of stomatology under current circumstance..
