Effect of transcutaneous acupoint electrical stimulation on inferior alveolar nerve block in patients with irreversible pulpitis

Objective To evaluate the effect of percutaneous acupoint electrical stimulation(TEAS)on the success rate of alveolar nerve block(IANB),pain and anxiety in the treatment of irreversible pulpitis of mandibular molars.Methods A total of 48 patients from the Department of Stomatology,Xuzhou Central Hospital from October 2020 to January 2021 who had irreversible pulpitis were randomly divided into experimental group(24 cases)and control group(24 cases)at ratio of 1∶1 using STATA 12.0.The information of group and treatment method was put into an opaque envelope numbered 1 to 48,and the patients meeting the inclusion criteria were recruited.Before their TEAS treatment,the information keeper handed them over to the acupuncturist and implemented the grouping scheme in the envelope.The experimental group was given bilateral Hegu and Laogong acupoints stimulated by TEAS,and the intensity was the maximum that the patients could tolerate.The stimulus intensity in the control group was 0 mA.Heft?Parker Visual Analog Scale(HP?VAS)values were recorded before TEAS stimulation(T0),after stimulation(T1)and during myelectomy(T2)to calculate pain scores.Visual Anxiety Scale(VAS?A)was used to record anxiety scores and IANB success rate of patients at T0 and T1.Chi?square test was used for the success rate of patients and two independent sample t test was applied for the remaining data.Results The success rate of IANB in the experimental group(79.2%)was significantly higher than that in the control group(33.3%),the difference was statistically significant(χ²=10.243,P=0.001).The T1 pain score of the experimental group[(66.2±5.2)mm]was lower than that of the control group(88.0±6.0)mm,and the difference was statistically significant(t=2.745,P=0.009).Compared with the control group T2[(65.4±5.6)mm],the T2 pain score of the experimental group(43.7±5.4)mm was also lower,the difference was statistically significant(t=2.786,P=0.008).Compared with the control group,T0 pain score(92.1±6.8)mm,T1 and T2 pain score of the control group decreased,the difference was statistically significant(tT1=3.951,PT1=0.000;tT2=3.035,PT2=0.004).There was no significant difference in pain scores between T1(88.0±6.0)mm and T0(92.1±6.8)mm in the control group(t=0.446,P=0.685).At T1,the anxiety score of the control group(3.0±0.2)was higher than that of the experimental group(1.1±0.2),and the difference was statistically significant(t=6.379,P<0.001).Anxiety scores in the experimental group were significantly decreased after TEAS treatment[T0(2.1±0.4)cm,T1(1.1±0.2)cm](t=2.288,P=0.027).Conclusion The application of TEAS before pulpitis can relieve pain,improve anxiety and improve the success rate of IANB in patients with irreversible pulpitis of mandibular molars.
