1、熱牙膠連續(xù)波垂直加壓充填技術(SystemB)和高溫牙膠熱塑注射充填法(Obtura2)相結合根管充填效果的研究劉敏蘇東旭馮艷華鄧剛(焦作市五官醫(yī)院河南焦作454000)【摘要】R的:觀察和分析熱牙膠連續(xù)波垂直加壓充填技術(SystemB)與高溫牙膠熱塑注射充填法(0btun2)聯(lián)合根管充填的根管封閉能力及臨床效果。方法:選取2012年6月到2014年8月患牙76顆,根管預備后隨機分為兩組,其屮分別對照組38顆使用單純Obtura2注射法,治療組38顆熱牙膠連續(xù)波垂直加壓充填技術SystemB與Obtura2聯(lián)合應用法進行根管充填,采用葡萄糖定量檢測法,填充后第1,10,15,20,25,30
2、天分別測定葡萄糖的濃度;并在37°C,100%濕度恒溫箱屮保存6個月后,進行染料滲透實驗和掃描電鏡觀察。結果:葡萄糖定量法檢測在第1天兩組間比較差異無顯著性意義(P>0.05>;第10天起,兩組滲漏量差異有顯著性意義(P<0.05);掃描電鏡顯示治療組根管充填材料與根管壁的結合最為緊密。結論:通過運用熱牙膠連續(xù)波垂直加壓充填技術(SystemB)與高溫牙膠熱塑注射充填法(Obtura2)聯(lián)合根管充填封閉效果優(yōu)于單純Obtun2注射式充填,值得臨床推廣應用.【關鍵詞】SystemB;Obtura2;根管充填;封閉能力【中圖分類號】R781【文獻標識碼】A【文章編號】1003-5028
