半导体激光辅助治疗牙周牙髓联合病变效果观察

Effect observation of semiconductor laser adjuvant therapy of periodontal pulp joint lesions

目的 探究半导体激光辅助治疗在牙周牙髓联合病变治疗中的效果。方法 选取牙周牙髓联合病变患者50例,年龄30-55岁,随机分为试验组和对照组,每组各25例。对照组患者采取根管治疗和牙周基础治疗。试验组患者在此基础上采取半导体激光辅助治疗。测定两组患者治疗前牙周探诊深度（PPD）、临床附着水平（CAL）、改良出血指数（mBI）,并于治疗后每3个月复查1次,关注其动态变化,以此评价半导体激光辅助治疗效果。结果 治疗后3个月,两组患者的PPD、CAL及mBI均较治疗前明显下降,且试验组患者的PPD下降程度更明显,与对照组比较差异显著（P〈0.05）;两组患者的CAL和mBI比较无显著差异（P〉0.05）。治疗后6个月,试验组患者的PPD、CAL、mBI仍持续下降,而对照组则无明显变化,试验组患者的各项指标与对照组比较均具有显著差异（P均〈0.05）。结论 在牙周牙髓联合病变的基础治疗后,使用半导体激光辅助治疗可以有效提高治疗效果,获得更为长期和稳定的预后。

Objective To explore the semiconductor laser assisted in the treatment of dental pulp joint lesions. Method 50 cases of periodontal pulp joint disease, 30 ~ 55 years old, were randomly divided into experimental group and control group, 25 cases in each group. Control group patients adopted root canal therapy and periodontal treatment. On the basis of control group, experimental group patients used semiconductor laser for adjuvant therapy. Measured before treatment periodontal probing depth（PPD）, clinical attachment level（CAL）, improved bleeding index（m BI）, and reviewed every 3 months after treatment, paid close attention to its dynamic change, and evaluated treatment effect of semiconductor laser auxiliary treatment. Result 3 months after treatment, PPD, CAL, and m BI of the two groups were significantly decreased, PPD of experimental group patients decreased more obviously, it was significant difference（P〈0.05）. CAL and m BI of the two group were no significant difference（P〉0.05）. 6 months after treatment, PPD, CAL, m BI of experimental group patients still continued declined, while control group had no significant change. Indicators of the two groups were significant differences（Pall〈0.05）. Conclusion After the basic treatment of periodontal pulp joint pathological changes, using the semiconductor laser as a means of adjuvant therapy can effectively improve the treatment effect, and get a more long-term and stable prognosis.
