生体活性ガラス系根管シーラーが根管充填後の術後疼痛発生率に及ぼす影響

本研究の目的は、生体活性ガラス系根管シーラーであるニシカ・キャナルシーラーBG（CS-BG）が根管閉塞（RCO）後の術後疼痛（PP）の発生率に及ぼす影響を評価することである。11名の歯科医師が555歯に対してパルペクトミーまたは感染根管治療を行った。RCO時にはCS-BGを使用した。RCO後、PPの発生率とPPに影響する因子（RCO中の痛みとRCO直後の痛み）を分析した。PPは8歯（1.5%）で観察され、RCO後7日以内に痛みを認めた歯はなかった。これらのPPを認めた歯では，RCO中の疼痛発生に有意差が認められたが，RCO直後の疼痛発生には，パルペクトミーおよび感染根管治療と比較して有意差は認められなかった．これらの臨床結果から，CS-BGは生体親和性に優れ，RCO時の患者の苦痛を抑制できることが示された．

The purpose of this study is to evaluate the effect of a bioactive glass-based root canal sealer, Nishika Canal Sealer BG (CS-BG), on the incidence of postoperative pain (PP) after root canal obturation (RCO). Eleven dentists performed pulpectomy or infected root canal treatments for 555 teeth. During RCO, CS-BG was used. After RCO, the rate of PP and the factors affecting PP (pain during RCO and pain immediately after RCO) were analyzed. PP was observed in eight teeth (1.5%), and within 7 days after RCO, there were no teeth with pain. In these teeth with PP, there was a significant difference in the occurrence of pain during RCO, but not in the occurrence of pain immediately after RCO, when compared with pulpectomy and infected root canal treatment. These clinical results show that CS-BG has an excellent biocompatibility, and can suppress the distress of patients during RCO.
