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