ZHANG Liang
Abstract：Objective:To assess the incidence and severity of postendodontic treatment pain(PEP) subsequent to root canal treatment(RCT) in vital teeth, necrotic pulp teeth and re-treatment teeth.Method:One hundred and thirty-seven patients undergoing RCT in our hospital from July 2011 to December 2012 were selected as the objects and devided into vital pulp group(n=70),necrotic pulp group(n=26) and re-treatment group(n=40) according to their different clinical manifestations.All patients were given the same procedure of RCT.The incidence and severity of postendodontic treatment pain(PEP) at 6 and 18 hours posttreatment of patients from different group were compared.Result:The incidence and severity of PEP in the vital pulp group(63.8%,2.46±1.4) were significantly higher than the necrotic pulp group(38.5%,1.78±1.2) and the re-treatment group(43.8%,1.89±1.1),the differences were statistically significant(P<0.05).Gender was significantly associated with the intensity of PEP.After treatment of 6,18 hours,women reported a higher mean pain intensity than men (2.29±1.38) versus (1.95±1.19) and (1.97±1.21) versus (1.68±0.99),the differences were statistically significant(P=0.034,0.041).Conclusion:RCT of teeth with vital pulp induce significantly higher incidence and intensity of PEP compared to teeth with necrotic pulp or re-treatment teeth.
