Many scientific works have shown the outstanding advantagesof microscopes applied in dentistry. The use of endodonticmicroscopes helps to identify symptoms, diagnose the diseasecorrectly, and detect the root canal more easily. With the remarkableadvantages of the microscope in terms of magnification and focus,the microscope really opens a new era for dentsitry in general andEndodontic in particular. In Vietnam, the research and application ofmicroscopy in endodontic treatment is still limited. In order toevaluate the applicability of microscopes in dental treatment ofendodontics, we conducted the study Study of microscopyapplication in root canal treatment of upper first molar with thefollowing objectives: 1. Describe the clinical and radiological features of the upperfirst molar indicated for endodontic treatment. 2. Assessing the effectiveness of microscope application in thetreatment of upper first molar. 3. Evaluation of the results of the upper first molar’s endodontictreatment. The need of the study Endodontic diseases always make up a high proportion in dentaldiseases. Endodontic treatment is an important area of restorativedentistry to restore function and aesthetics to diseased teeth. Theupper first molar is one of the earliest erupted teeth and has the mostendodontic treatment, but the rate of failure of endodontic treatmentis the highest among the molar teeth. Many studies show that thepresence of MB2, as well as unsatisfactory cleaning of the pulpchamber, is the main cause of treatment failure. Therefore, theapplication of technical advances such as dental microscopes todetect root canals, wall crevices, pulp chambers, granules andcalcified blocks is extremely necessary to support the dentist indetect, clean, shape the canal, and pulp chamber treatment. 2 New contributions of the study - This is a research project following the new trend of microscopeapplication in the accurate diagnosis and examination of fissuresbefore and during treatment, the discovery of calcified particles andcalcification chamber, and management of complications whenencountered in the treatment of upper first molar. - The thesis specifically evaluates the efficiency of using amicroscope to detect the orifice of the root canal, of which the mosteffective is to detect the MB2 is much higher than naked eye. - The results of the study are monitored up to 24 months aftertreatment, which is long enough to generalize the results, makingrecommendations in the application of microscopes in endodontictreatment. Layout of the thesis The thesis has 143 pages, including sections: problem statement (2pages), introduction (44 pages), subjects and research methods (18pages), results (47 pages), discussion (29 pages), conclusion (2 pages),Suggestion (1 pages), The thesis has 49 tables, 47 pictures, 8 charts, 1diagram. 131 references including Vietnamese and English documents. CHAPTER 1: INTRODUCTION1.1. Anatomy of the upper first molar root canal system The upper first molar is the earliest permanent tooth, so it is thefirst to decay. Upper first molar has three root: two buccal root (MBand DB) and one platal root. Each root corresponds to 1 root canal,sometimes 2 canals, usually found in the proximal canal.1.1.1. Outer anatomy Viewed from the occlusal surface: The contour is usually diamondshape. Three large cusps form a typical pattern for maxillary molarteeth, which are linked together into a triangle. These are importantanatomical landmarks applied when opening pulp for endodontictreatment of the upper fist molar teeth.1.1.2. Inner anatomy The in ...
