Nd:YAG激光治疗急性局限性智齿冠周炎的临床观察

Clinical observation on treatment of acute wisdom tooth pericoronitis with neodymium:Yttrium-Aluminum-garnet Laser

目的:观察口腔钕激光(neodymium:yttrium-aluminum-garnet,Nd:YAG)治疗急性局限性智齿冠周炎的临床疗效。方法:选取114例急性局限性智齿冠周炎患者,局部用3%过氧化氢和生理盐水交替冲洗后棉球擦干,随机分为3组,A组Nd:YAG激光组(n=38):Nd:YAG激光低强度治疗(LLLT)模式,具体选择参数:MSP,1.5 W,100 m J,15Hz,非接触局部移动照射病变区肿胀软组织10 min,B组(n=38):局部肿胀龈袋注人适量盐酸米诺环素软膏1次;C组(n=38):局部龈袋置入2%碘甘油,1次/d×3 d。所有治疗组均未全身用药,第4 d观察疗效。结果:和C组比较,A,B组局部炎性肿胀症状均有明显改善,总有效率分别为89.47%和78.95%,A,B两组间疗效无显著性差异(P>0.05)。A,B组的疗效均显著好于C组(P<0.01;P<0.05.);与B,C组比较,A组患者自觉疼痛明显减轻(P<0.01)。结论:Nd:YAG激光治疗急性局限性智齿冠周炎具有较好临床疗效。

Objective： To study the efficacy of neodymium： yttrium- aluminum-garnet laser of curing acutewisdom tooth pericoronitis, comparing with iodine glycerine. Method： 57 cases of acute wisdom tooth pericoronitis were selected and randomly separated into 3 groups, whose local parts were washed with 3 % hydrogen peroxide,and physiological saline consecutively, and dried clearly. For patients in group A test sides were treated with the Nd： YAG laser （1064 nm, MSP, 1.5 W, 100 mJ, 15 Hz）. Clinical assessments （total effective rate of local treatment and visual analog scale of pain） were performed pre-treatment and at 4 days post treatment, B,minocycline hydrochloride ointment was injected on their infected areas once. Patients in Group C were treated with 2 % iodine glycerine once everyday in 3 days. Efficacy of all experimental treatments were observed at the 4th day. Result：The symptoms of group A an B were mitigated obviously,whose ratio of effectiveness was 89.47 % and 78.95 % respectively, without significant difference （P 〉0.05）, and were all better than that of group C （63.16 %, P 〈0.01 P 〈0.05.）. Conclusion： Nd： YAG laser is good in curing acute wisdom tooth pericoronitis.
