    While citing references, we discuss the surgical methods and results of arthroscopic surgery of the temporomandibular joint at our department. Our subjects were 51 patients with 71 affected joints. These included 9 men with 10 affected joints, and 42 women with 61 affected joints. The average age of the male patients was 31.6 years (range ; 17-47 years), while that of the female patients was 34.3 years (range ; 17-74 years). Preoperatively the average mouth opening was 28.3 ± 6.6mm, and that improved significantly to 39.8±5.0mm postoperative (p<0.01). The VAS for temporomandibular pain and impaired daily living activity was 4.9±2.6 and 5.1±2.7 preoperative respectively, One month postoperative it was 1.5±1.5 (p<0.01) and 1.0±1.6 (p<0.05), respectively and three months postoperative was approximately one tenth of what it had been preoperatively. Of the 51 patients, there were 36 "significantly improved" cases (70.6%), 10 "improved" cases (19.6%), and 5 "mildly improved" cases (9.8%), and as a result, the efficacy rate was 90.2%.

    We analyzed trace elements in 100 normal oral mucosae by Particle Induced X-ray Emission (PIXE) method. We studied 48 males and 52 females, 11 to 77 years of age with a mean age of 31.6 years. The submajor elements Na, P, S, Cl, K and Ca were detected in all samples, and Mg was detected in 97% of the samples. Twelve trace elements, Si, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Se, Mo and Sn, were detected in the oral mucosae. Of these trace elements, Si, Cr, Mn, Fe, Ni, Cu, Zn and Se were detected in greater than 80% of the samples. We detected six ultratrace elements Ge, As, Br, Rb, Pd and Cd. Of these ultratrace elements, Br and Rb were detected in greater than 90% of the samples. Fourteen contaminated elements were detected in the oral mucosae. Al and Pb were detected in all samples, although contaminated elements do not normally exist in human body. There were significantly higher mean concentration values of Se and Pb in the males than in the females. There were significantly different concentration values of S and Cr, according to age groups.

    The pumping lavage system(PLS), a lavage technique for the upper joint cavity, cleans inside the upper joint cavity by repeated pressurized injection and aspiration of physiological saline through a single puncture. With existing PLS methods, the surgeon uses a syringe to inject physiological saline into the upper joint cavity based on tactile sensations at the fingertips, and as a result, pressure inside the upper joint cavity could potentially build up. In addition to this risk, the lavage procedures themselves are complicated. We have been obtaining favorable results using a pressurized bag with PLS to directly inject physiological saline from a transfusion bottle. When a pressurized bag is used with PLS, physiologcal saline can be injected at a specific pressure, thus partially simplifying the lavage procedure and improving the safety aspect. The efficacy of PLS using a pressurized bag was 81.3%.

    通常臨床歯科医学における骨移植は,その病理学的形態より3壁性骨欠損を有する歯周病患者に対して広く行われている。今回,下顎前歯部(下顎結合部)唇側面歯槽骨の開窓や限局性穿孔は存在するが,歯肉退縮を生じていない骨格型III級不正咬合患者へ顎矯正手術と同時に自家骨移植を付加的に行った。初診時のセファログラム所見より高く幅の狭い下顎結合部とこの薄い骨に直立している下顎前歯が確認された。また,術前矯正歯科治療中,下顎前歯はその捻転の解消と頬舌的な移動が行われた。手術時には下顎前歯部の開窓や限局性穿孔が確認された。下顎前歯部(下顎結合部)唇側面に自己海面骨を移植することによって歯槽骨の開窓や限局性穿孔は覆われた。結果的にセファログラム上での経過所見より,その後4年10か月間移植骨の残留が認められ,さらに臨床的に咬合が安定し通常後戻りしやすいとされる下顎前歯捻転の後戻りも認められず良好な結果を得たので報告した。
