自酸蚀粘接剂对活髓基牙的保护治疗效果分析

Study the Protective Effect of Self-etching Adhesive on the Treatment of Vital Pulp Abutments

目的分析自酸蚀粘接剂对活髓基牙的保护治疗效果。方法方便选择2015年8月—2017年2月收治的126例采用金属烤瓷固定桥修复治疗的患者并随机分组。对照组未采取任何保护措施,保护组在备牙后立刻采用自酸蚀粘接剂对活髓基牙进行保护。比较两组磨牙和前磨牙治疗前VAS评分、粘冠前VAS评分、粘冠后VAS评分、粘冠后4周VAS评分。粘冠前和粘冠后4周生活质量评分。结果两组患者磨牙和前磨牙粘冠前VAS评分均最高,在粘冠后VAS评分、粘冠后4周VAS评分均显著降低,和粘冠前VAS评分对比差异有统计学意义(P<0.05),其中,对照组磨牙治疗前、粘冠前、粘冠后、粘冠后4周VAS评分分别是(0.13±0.15)分、(3.67±2.12)分、(0.91±0.23)分、(0.24±0.11)分,保护组分别是(0.13±0.14)分、(3.67±2.11)分、(0.91±0.24)分、(0.25±0.11)分。对照组前磨牙治疗前、粘冠前、粘冠后、粘冠后4周VAS评分分别是(0.14±0.23)分、(4.34±0.23)分、(0.83±0.33)分、(0.36±0.12)分,保护组分别是(0.13±0.24)分、(4.34±0.22)分、(0.81±0.33)分、(0.37±0.15)分。粘冠前两组生活质量评分相近(P>0.05);粘冠后4周保护组生活质量评分中躯体功能、情感功能、社会功能分别为(84.46±13.11)分、(86.91±14.56)分、(93.36±18.22)分,优于对照组(63.10±9.65)分、(72.17±10.98)分、(80.42±13.11)分,(t=5.244、8.322、7.134,P<0.05)。结论自酸蚀粘接剂对活髓基牙并无明显保护作用,无论有无使用自酸蚀粘接剂,只要冠桥修复体具有较高的质量,可显著降低基牙备牙后敏感症状,减轻患者疼痛感。因此,为有效减少活髓基术后敏感性和疼痛度,需选择边缘密合度高的修复体,并做好粘固工作。

Objective This paper tries to analyze the self etching adhesive on the vital pulp teeth protection treatment.Methods 126 cases using the PFM fixed bridge restoration treatment from August 2015 to February 2017 were convenient selected and randomly grouped.The control group did not take any protective measures,the protective group in the tooth after the preparation immediately by the protection of vital abutment self etching adhesive.Comparison of two groups of molars and premolars before treatment VAS score,VAS score before sticky sticky crown,crown after the VAS score,VAS score after 4 weeks of stick crowns was implemented.Quality of life score of 4 weeks before and after the crown stick were compared.Results The VAS scores of the two groups were highest before and after the crown sticking.The VAS score of the sticking crown and the VAS score of the 4th week after sticking crown were significantly lower than those before the sticking crown(P<0.05).The VAS scores of the control group before treatment,before sticking the crown,after sticking the crown,and 4 weeks after sticking the crown were(0.13±0.15)points,(3.67±2.12)points,(0.91±0.23)points and(0.24±0.11)points,respectively,while those in the protection group were(0.13±0.14)points,(3.67±2.11)points,(0.91±0.24)points,(0.25±0.11)points.The VAS scores in the control group before premolar treatment,before sticking the crown,after sticking the crown,4 weeks after sticking crown were(0.14±0.23)points,(4.34±0.23)points,(0.83±0.33)points and(0.36±0.12)points,respectively,and those in the protection group were(0.13±0.24)points and(4.34±0.22)points,(0.81±0.33)points,(0.37±0.15)points.The quality of life scores of the two groups before sticking crown were similar(P>0.05);the body function,emotional function and social function in the quality of life protection group were(84.46±13.11)points,(86.91±14.56)points and(93.36±18.22)points respectively,in the control group,(63.10±9.65)points,(72.17±10.98)points and(80.42±13.11)points,respectively(t=5.244,8.322,7.134,P<0.05).Conclusion Self-etching adhesives have no significant protective effect on live pulp abutments,with or without the use of self-etching adhesives,as long as the crown bridge restoration has a high quality,which can significantly reduce the sensitive symptoms of abutment preparation teeth,reduce pain in patients.Therefore,in order to effectively reduce the sensitivity and pain of post-marrow biopsy,it is necessary to choose a prosthesis with high edge adhesion and do a good job of cementing.
