Abstract: Objective To evaluate the value of periodontal pulp combined with semiconductor laser in the treatment of severe periodontitis. Methods A total of 86 patients with severe periodontitis (86 teeth) from June 2017 to June 2019 were selected by simple random sampling. They were divided into two groups by drawing lots, 43 cases in each group. The control group received periodontal pulp treatment, and the study group received periodontal pulp combined with semiconductor laser therapy. The therapeutic effects of the two groups were compared. Results After treatment, the levels of interleukin-4 (IL-4) and tumor necrosis factor-α (TNF-α) in the study group were (15.82±5.05) ng/L and (0.95±0.12) ng/L, lower than those in the control group [(19.03±5.11) ng/L, (1.06±0.19) ng/L] (both P<0.05); probing depth (PD), loss of attachment (CAL), sulcus bleeding index (SBI) in the study group [(5.18±0.55) mm, (5.46±0.49) mm, (2.62±0.75) mm] were lower than those in the control group [(5.51±0.51) mm, (5.81±0.55) mm, (3.03±0.82) mm] (all P<0.05); the bleeding rate of the study group was 4.65% (2/43), lower than that of the control group [20.93% (9/43)] (P<0.05); the tooth looseness score of the study group [(0.58±0.13)] was lower than that of the control group [(0.72±0.24)] (P<0.05); the total effective rate of the study group was 93.02% (40/43), higher than that of the control group [76.74% (33/43)] (P<0.05). Conclusion In severe periodontitis, the combination of periodontal pulp and semiconductor laser therapy can reduce the inflammatory reaction, improve the periodontal index, and enhance the curative effect.

摘要： 目的 探讨重度牙周炎采取牙周牙髓联合半导体激光治疗的价值。方法 简单随机抽样法选取2017年6月至2019年6月本院86例重度牙周炎患者,共86颗患牙。抽签法分为两组,每组43例。对照组给予牙周牙髓治疗,研究组给予牙周牙髓联合半导体激光治疗。比较两组治疗效果。结果 治疗后,研究组白介素-4(IL-4)、肿瘤坏死因子-α(TNF-α)水平[(15.82±5.05)ng/L、(0.95±0.12)ng/L]低于对照组[(19.03±5.11)ng/L、(1.06±0.19)ng/L](均P<0.05);研究组探诊深度(PD)、附着丧失(CAL)、龈沟出血指数(SBI)[(5.18±0.55)mm、(5.46±0.49)mm、(2.62±0.75)mm]低于对照组[(5.51±0.51)mm、(5.81±0.55)mm、(3.03±0.82)mm](均P<0.05);研究组探诊出血率4.65%(2/43),低于对照组20.93%(9/43)(P<0.05);研究组牙齿松动度评分[(0.58±0.13)分]低于对照组[(0.72±0.24)分](P<0.05);研究组总有效率为93.02%(40/43),高于对照组76.74%(33/43)(P<0.05)。结论 重度牙周炎中应用牙周牙髓联合半导体激光治疗可减轻炎症反应,改善牙周指标,增强疗效。
