四手操作模式预防妊娠期急性牙髓炎患者交叉感染的效果及对口腔细菌微生态的影响

Effect of Four-hand Operation Mode on Preventing Cross-infection in Patients with Acute Pulpitis of Pregnancy and Its Influence on Oral Bacterial Microecology

目的:研究四手操作模式预防妊娠期急性牙髓炎患者交叉感染的效果及对口腔细菌微生态的影响。方法:选取2019年5月—2020年5月在瑞金市妇幼保健院就诊的妊娠期急性牙髓炎患者124例,采用随机抽签法分为二手操作组和四手操作组,各62例。二手操作组给予二手操作技术治疗,四手操作组给予四手操作技术治疗。比较两组患者治疗前后聚合酸杆菌、福赛坦氏菌、中间普氏菌、卟啉单胞菌、放线杆菌检出率,龈沟出血指数(SBI)、探诊深度(PD)、菌斑指数(PLI)、口气值,以及治疗时间、交叉感染发生情况、治疗效果。结果:两组治疗后各种细菌检出率、PLI、SBI、PD、口气值均低于治疗前(P<0.05);与治疗后二手操作组相比,四手操作组各种细菌检出率、PLI、SBI、PD、口气值均更低,差异均有统计学意义(P<0.05);与二手操作组相比,四手操作组患者治疗时间更短,交叉感染率更低,治疗总有效率更高,差异均有统计学意义(P<0.05)。结论:四手操作模式能有效预防妊娠期急性牙髓炎患者交叉感染发生,改善患者口腔细菌微生态及牙周状况,治疗效果较好。

Objective:To study the effect of four-hand operation mode on preventing cross-infection in patients with acute pulpitis of pregnancy and its influence on oral bacterial microecology.Method:A total of 124 patients with acute pulpitis of pregnancy who were treated in Ruijin Maternal and Child Health Care Hospital from May 2019 to May 2020 were selected and divided into the second-hand operation group and the four-hand operation group according to random drawing method,with 62 cases in each group.The second-hand operation group was given the second-hand operation technique treatment,and the four-hand operation group was given the four-hand operation technique treatment.Detection rates of Polyacid bacteria,Fossettan bacteria,Prevotella intermedia,Porphyromonas and Actinobacillus,sulcus bleeding index(SBI),probing depth(PD),plaque index(PLI)and halitosis value of before and after treatment,treatment time,occurrence of cross-infection and treatment effect were compared in two groups.Result:After treatment,the detection rate of various bacteria,PLI,SBI,PD and halitosis value in both groups were lower than those before treatment(P<0.05).Compared with the secondhand operation group after treatment,the detection rate of various bacteria,PLI,SBI,PD and halitosis value in the four-hand operation group were lower,the differences were statistically significant(P<0.05).Compared with the second-hand operation group,the treatment time in the four-hand operation group was shorter,the crossinfection rate was lower and the total effective rate was higher,the differences were statistically significant(P<0.05).Conclusion:Four-hand operation mode can effectively prevent the occurrence of cross-infection in patients with acute pulpitis of pregnancy,improve the oral bacterial microecology and periodontal status of patients,and the treatment effect is good.
