文题释义:
米诺环素在口腔疾病中的应用
:研究表明有效浓度的米诺环素可减少骨有机质的降解,影响破骨细胞的形态功能,抑制骨吸收,利于骨形成。米诺环素能显著抑制胶原酶的活性,阻止牙周组织的破坏,抑制胶原酶代谢,促进牙周组织再生,能显著缓解临床症状。近来有研究表明,米诺环素对慢性牙周炎疼痛症状的缓解及在牙周牙髓联合病变中辅助根管治疗都具有良好的疗效。目前国内外研究主要着眼于米诺环素应用在牙周疾病、牙周牙髓联合病变、干槽症、智齿冠周炎、种植体周围炎、义齿性口炎等疾患治疗,少见其在根管治疗中作为根管消毒药物的实验研究。

背景:米诺环素作为根管消毒药物,其疗效、安全性及免疫学评估尚需相应实验证明。
目的:观察米诺环素对根管渗出液体积及白细胞介素17水平的影响。
方法:试验组纳入根尖周病急性期需进行根管治疗的患者16例,随机分为2组,氢氧化钙组以氢氧化钙糊剂消毒根管,米诺环素组以米诺环素缓释剂软膏消毒根管,1周后复诊,检测根尖周指数、根尖周渗出液体积及白细胞介素17水平,完成根管充填;对照组纳入牙髓正常但需要进行根管治疗的患者16例,行一次性根管充填,检测根尖周指数、根尖周渗出液体积及白细胞介素17水平。
结果与结论:①试验组根尖周渗出液体积及白细胞介素17水平均高于对照组(P < 0.05);②米诺环素组、氢氧化钙组治疗1周后的根尖周指数、白细胞介素17水平均低于治疗前(P < 0.05);③米诺环素组与氢氧化钙组治疗1周后的根尖周指数、根尖周渗出液体积及白细胞介素17水平比较差异均无显著性意义;④结果表明,米诺环素通过抑制白细胞介素17的表达降低根尖周病根尖区炎症的渗出,有效治疗根尖周病。

Abstract:

BACKGROUND: Experimental proof for the efficacy, safety, and immunological assessment is needed when minocycline is used for root canal disinfection.
OBJECTIVE: To investigate the effect of minocycline for root canal disinfection on levels of interleukin-17 in apical exudates of periapical periodontitis and periapical exudate volume.
METHODS: Sixteen patients with acute periapical periodontitis (16 teeth) scheduled for root canal therapy were enrolled and randomly divided into calcium hydroxide and minocycline groups, respectively, followed by root canal disinfection. One week after disinfection, periapical index, periapical exudate volume and interleukin-17 level were detected prior to the root canal filling. Another 16 patients with normal pulp vitality (16 teeth) scheduled for single root canal filling were enrolled as control group, in which periapical index, periapical exudate volume and interleukin-17 level were detected.
RESULTS AND CONCLUSION: The periapical exudate volume and interleukin-17 level in the calcium hydroxide and minocycline groups were significantly higher than those in the control group (P < 0.05). The periapical index and interleukin-17 level in the calcium hydroxide and minocycline groups were decreased significantly at 1 week after root canal disinfection (P < 0.05), while there was no difference between these two experimental groups in the periapical index, periapical exudate volume and interleukin-17 level. To conclude, the use of minocycline significantly reduces interleukin-17 level and periapical exudate volume, and thus achieves effective outcomes in periapical disease.
