RESUMO
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.

With the progress of technology, three-dimensional (3D) printing technology has become more and more widely used in stomatology. 3D printed template has played an irreplaceable role in oral implantation; at the same time, 3D printed template, which has been successfully applied to the calcified root canal negotiation, endodontic treatment of dental invaginatus, apical surgery and autotransplantation, has also provided a new concept and treatment mode for the diagnosis and therapy of endodontic diseases. This review, summarized the research and application of 3D printed template from the perspective of the treatment of endodontic deseases.

RESUMO
Objective To explore the expression and significance of adhesion molecules ?2 integrin CD11c, CD18 in the polymorphonuclear neutrophils (PMN) and mononuclear leukocytes (MNL) of peripheral blood in patients with acute ischemic stroke (AIS).Methods Using indirect immunofluorescence and adopting a flow cytometry, the expressions of CD11c, CD18 in PMN and MNL in peripheral blood were measured within 72 h and 7 d after onset in 28 patients and 28 healthy controls.Results In AIS group, the expressions of CD11c, CD18 in PMN and MNL within 72 h ( 20.82?5.88, 218.25?89.00, 34.78?14.56 and 286.75?95.50, respectively) and at 7 d ( 18.60?5.52, 185.52?68.44, 31.97?14.47and 247.00?88.06, respectively) were significantly higher than those of normal control group ( 15.63?3.01, 150.76?41.20, 20.20?8.50 and 186.38?52.97, respectively)(all P
