印象採得時の循環動態変動に対する体位の影響第1報 健康成人について
Get PDFapplication/pdfWe examined the circulatory changes during impression taking and the effect of posture in 41 healthy adults. We took the impressions of upper and lower arches separately, both in the supine and sitting positions, using an alginate impression material. Blood pressure and pulse rates were measured noninvasively with a bedside monitor (Bioview 1000^[○!R]) at the following times : (1) after 10 minutes of rest ; (2) shortly before the insertion of the impression material ; (3) shortly after the insertion of the impression material ; (4) after 1 minute of holding the impression material in the mouth ; and (5) after it was removed. Blood pressure was significantly lower during impression taking compared to at rest. There was no significant influence of posture on circulatory changes during impression taking.journal articl

摘出した形状記憶インプラント周囲組織の金属イオン
Get PDFapplication/pdfRecently titanium and titanium alloys have been widely used for dental implants. Shape-memory alloy implants of these implants are composed of nickel and titanium. This alloy has little adverse effect on the body. We report a case of shape-memory alloy implant removed due to peri-implantitis. Bone loss was observed around the implant due to peri-implant inflammation on X-ray examination. This shape-memory alloy implant was removed, and the soft tissue around the implant was examined using X-ray microanalyzer to analyze the constructive element. These results show that Ni and Sn, dissolute in periimplant tissue.journal articl
歯内療法のニューウェーブ
Get PDFapplication/pdfAs high technology has recently been introduced in endodontics, there has been major progress in the concept, instruments and techniques of endodontic treatment. In this manuscript, present situations of this new trend were summarized and discussed by showing some new topics that attracted attention such as new changes and development of new instruments or materials. 1. Conservative treatment of infected pulp The concept of lesion sterilization and tissue repair (LSTR) therapy was shown as a method of avoiding pulpectomy that leads to loss of the tooth as much as possible, and its effectiveness and indication were discussed. 2. The advances in root canal preparation and a new method The history of root canal preparation techniques was reviewed, and Nickel-Titanium files with super elasticity, which have attracted much attention for the application to curved canal enlargement, were evaluated by comparing with conventional instruments. 3. Laser application to endodontics The effects of various kinds lasers were discussed in relation to the areas of endodontics where each laser is applied. 4. Intracanal medication with calcium hydroxide The use of calcium hydroxide, which has recently attracted attention as an intracanal medicament, was discussed, by showing its effectiveness and some technical problems in clinical application. 5. Microendodontics Advantages and potential of endodontic procedures using dental operation microscopes were summarized. 6. New development of root canal obturation techniques and root canal filling materials Some negative aspects of the root canal obturation technique, which is the main current method of root canal filling, were pointed out, and the obturation method that has been studied based on a new concept was discussed.journal articl
