??Cone beam computed tomography ??CBCT?? changes the traditional method of oral X-ray imaging. In endodontics?? CBCT is a reliable and nondestructive examination method. It’s sub millimeter spatial resolution and image information of hundreds of megabytes constitute a technical platform for the precision medicine of endodontics?? which provides strong guarantee for evidence-based medicine. There is no doubt that the age of big data makes the fine diagnosis of the ultrastructure of the dental pulp tissue a new concept.

近15年来,影响根管治疗质量的最重要因素之一就是手术显微镜的引入和推广应用。手术显微镜多级放大功能和良好的照明技术,使医生能够看清髓室底及根管内部结构,精确定位手术位置,把握操作细节,从而改善并提高根管治疗术的质量。显微根管治疗可以对传统根管治疗无法完成或难以完成的病例包括根管遗漏、塑化根管、钙化根管、根管台阶形成、器械断针、侧壁穿孔等进行治疗,使更多患牙得以保留。本文结合笔者的临床经验及国内外文献,对根管手术显微镜的组成、显微治疗辅助设备器械的功能和显微镜在疑难根管治疗中的应用等进行评述。强调根管显微镜在疑难病例治疗中的重要性和必要性,并提出在进行显微根管治疗前须进行显微镜应用技巧培训。

??Digital medical as a product of digital technology combined with medicine??has gotten rapid development in recent years. Digital 3D printing is a newly emerged technology in this background. Digital 3D printing technology has changed the traditional medicine pattern??especially in the field of surgical medical. It mainly reflects in evaluation and forecast risk before the operation??real-time navigation in the process of the operation and evaluation of surgical effects after the operation.This paper introduces the application of digital 3D printing technology in the treatment of OSAHS.

??Root canal debridement and infection control are two of the main steps in root canal therapy. Bacteria will be present as biofilm colonies inside the root canal??and it will be well within fins??intercanal anastomoses??apical ramification??apical furcation or lateral accessory canal. Meanwhile??during the cleaning and shaping process??smear layer can be produced??which can be used for the viable bacteria inside the complex anatomical structure to sustain growth and activity. In addition??due to the complexity of the root canal system??the conventional irrigation and disinfection technology is superficial??then the smear layer and Enterococcus faecalis biofilms are difficult to remove. In recent years??lasers??as a novel adjuncting irrigation tool??are used clinically??such as Er??YAG laser and Er??Cr??YSGG laser. As is reported??laser-activated irrigations can effectively remove the smear layer and the infection and obtain better disinfection rates. So in this a review??we made a summary of the effect of laser-activated irrigations on endodontics.

??Temporomandibular joint??TMJ??is one of the most complex joints of the human body. For its deep location??we often need the help of imaging methods to study it. Because of image overlap and distortion??the traditional two-dimensional imaging methods are not accurate. Cone beam CT??CBCT??overcomes the shortcomings of the traditional two-dimensional imaging methods??and can analyze the TMJ in three-dimensional direction??which is important to the clinical diagnosis and pathological treatment.

??Objective    To estimate the three-dimensional effects of thermomechanical condensation by comparing the effects of thermomechanical condensation?? continuous-wave condensation and cold lateral condensation. Methods    The roots of sixty extracted human anterior teeth were divided into three groups randomly after preparation. After root canal filling with the three techniques?? thermomechanical condensation ??group A?? n=20???? continuous-wave condensation ??group B?? n=20?? and cold lateral condensation ??group C?? n=20???? the teeth were scanned by high resolution micro-computed tomography ??micro-CT??. Then?? the teeth were sliced at 3 mm?? 6 mm?? and 9 mm from the apical foramen. The cross-sections were observed using scanning electron microscopy ??SEM??. The percentage of void area were measured using Image J image processing software?? and all measurements were analysed by SPSS 17.0 software. Results    Both micro-CT and SEM indicated that the percentage of void area in group A was equal to that in group B ??P > 0.05??. And the percentage of void area in both group A and group B were significantly lower than that in group C ??P < 0.05??. Conclusion    The three-dimensional effects of the thermomechanical condensation technique are equal to the effects of the continuous-wave condensation technique and are superior to the traditional cold lateral condensation technique.
