| Objective:The objective of this study was to evaluate the clinical effectsof GuttaFlow through comparing the postoperation pain incidence rate and itspain level between the GuttaFlow and Zinc oxide iodoform sealer,so that it couldprovide the experimental basis for the GuttaFlow used in clinical practice.Methods:60cases of outpatients,a total of60living marrow permanent teethwhich were diagnosed as pulp pathema and need to receive root canal treatment.Theteeth were divided into experimental group and control group at random by theregistration order. The inclusion criteria was that all patients were healthy,withoutdrug allergy and had diagnosisd by clinical examination and X-ray.All teeth hadnever received any root canal treatment.The teeth were prepared by TF(Twisted Files)nickelï¼titanium instrument.Using calcium hydroxide as an interappointmentmedicament,temporarily sealed and obturated after one week.The teeth inexperimental group (n=30) were filled with GuttaFlow+cone technique, while thosein control group (n=30) were filled with Zinc oxide iodoform sealer andgutta-percha using a lateral compaction technique.Conventional filling cavities afterthe shooting postoperative X-ray film and root canal just charge.1~7d after treatmentis the observation period.Explaining to the patients if had pain, swelling and othercomplications, come to review.Results:One week after root canal filling,the pain incidence of experimentalgroup was6.7%,control group was26.7%, so the effect of experimental group wasbetter than control group(P<0.05) and pain grade II grade difference wasstatistically(P<0.05).Conclusions:The treatment with GuttaFlow in root canal filling can reducethe postoperative pain significantly and better than Zinc oxide iodoform sealer in thepain grade II. |
