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 observe the clinical efficacy of oral neodymium (Yttrium-aluminum-garnet, Nd: YAG) in the treatment of acute confined wisdom teeth. Methods: One hundred and fourteen patients with acutely-limited wisdom pericoronis were randomly divided into 3 groups: group A Nd: YAG laser (n = 38) (LLLT) mode of Nd: YAG laser with specific choice of parameters: MSP, 1.5 W, 100 m J, 15 Hz, non-contact local movement of the swollen soft tissue in the diseased area for 10 min, Gingival parenteral injection of minocycline hydrochloride ointment once; C group (n = 38): local gingival bags with 2% iodine glycerol, 1 times / d × 3 d. All treatment groups were not systemic medication, the first 4 d observed efficacy. Results: Compared with group C, the symptoms of local inflammatory swelling in group A and group B were significantly improved. The total effective rates were 89.47% and 78.95% respectively. There was no significant difference between groups A and B (P> 0.05). The curative effect of group A and B were significantly better than that of group C (P <0.01; P <0.05). Compared with group B and C, the pain of group A was significantly reduced (P <0.01). Conclusion: Nd: YAG laser treatment of acute confined wisdom pericoronitis has good clinical efficacy.
