【摘要】:目的:比較不同溫度與輔助器械對根管內(nèi)玷污層的清除效果。方法:對60顆離體單根牙進行根管預(yù)備,20℃或60℃的NaOCl作為沖洗液,被動超聲(PUI)或聲波沖洗裝置EndoActiator(EA)或側(cè)方開口沖洗針輔助沖洗,隨機分組(n=10):20℃-PUI組、20℃-EA組、20℃對照組、60℃-PUI組、60℃-EA組和60℃對照組。用熱場發(fā)射掃描電鏡觀察,Hulsmann標(biāo)準評估玷污層清除效果。結(jié)果:60℃組玷污層清除效果優(yōu)于20℃組(P0.05);20℃-PUI組、20℃-EA組效果均優(yōu)于20℃對照組(P0.05)。結(jié)論:NaOCl的溫度是影響玷污層清除效果的主要因素,60℃NaOCl比20℃NaOCl更有效。
