【摘要】：目的：應(yīng)用Er,Cr:YSGG激光治療中老年根面齲,從充填體的微滲漏和在治療過(guò)程中對(duì)疼痛評(píng)估兩方面進(jìn)行實(shí)驗(yàn)室及臨床研究,為Er,Cr:YSGG激光在臨床應(yīng)用提供理論依據(jù)。方法：(1)收集根面有齲壞的離體牙40顆,觀察組用Er,Cr:YSGG激光去腐備洞,對(duì)照組用高速渦輪機(jī)去腐備洞,每組20顆；觀察組再隨機(jī)分為A組采用富士Ⅱ型玻璃離子水門汀充填,B組自酸蝕下復(fù)合樹(shù)脂充填,對(duì)照組充填方法同觀察組,采用熱力循環(huán)法和染料滲透法處理充填后的離體牙,體視顯微鏡和掃描電鏡下觀察微滲漏情況。(2)選取年齡在50～60歲的根面齲患者,男女各15例,共60顆患牙,要求每個(gè)病例口內(nèi)至少有2個(gè)同名牙(同頜或?qū)︻M)齲壞程度相似,分別采用Er,Cr:YSGG激光(觀察組)和高速渦輪機(jī)(對(duì)照組)去腐備洞。術(shù)后采用面部表情量表對(duì)患者治療過(guò)程中的疼痛進(jìn)行評(píng)估。結(jié)果：(1)采用富士Ⅱ型玻璃離子水門汀和自酸蝕下復(fù)合樹(shù)脂充填后的離體牙,觀察組和對(duì)照組的染料滲漏情況無(wú)統(tǒng)計(jì)學(xué)意義(P0.05)；觀察組和對(duì)照組充填體邊緣微縫隙在頜壁、齦壁的間隙寬度差異無(wú)統(tǒng)計(jì)學(xué)意義(P0.05);(2)Er,Cr:YSGG激光可以減輕根面齲去腐備洞過(guò)程中的疼痛,差異具有統(tǒng)計(jì)學(xué)意義(P0.05)。結(jié)論：(1)應(yīng)用Er,Cr:YSGG激光對(duì)根面齲去腐充填后,不會(huì)降低微滲漏的發(fā)生率；(2)Er,Cr:YSGG激光在根面齲去腐備過(guò)程中可以明顯減輕疼痛和不適,可作為微創(chuàng)無(wú)痛治療根面齲的選擇之一。
[Abstract]:Objective: to study the treatment of root caries in the middle and old age by using Ernst Cr: YSGG laser. The laboratory and clinical studies on the microleakage of the filling body and the pain assessment during the treatment were carried out to provide the theoretical basis for the clinical application of Ernchr Cr: YSGG laser. Methods 40 decayed teeth with decayed root surface were collected in the observation group and 20 holes in each group were removed by err Cr: YSGG laser and 20 by high speed turbine in the control group. The observation group was randomly divided into two groups: group A was filled with Fuji type 鈪，
