Clinical Effffects of Two Kinds of Nickel-Titanium Instruments in Root Canal Therapy of Primary Molars
Objective To explore the effect of Reciproc Nickel-titanium instumenst and Protaper Nickel-titanium instruments in root canal therapy of primary molars.Methods A total of 50 children with primary dental pulp disease visited the department of stomatology at Affiliated Hospital of Gansu University of Chinese Medicine from January 2020 to January 2021 were selected,which were treated with Reciproc nickel titanium instruments(RE group)and Protoper nickel titanium instruments(PT group)were used for root canal treatment.The operation time,endodontic interappointment pain and postoperative X-ray were recorded.The root canal therapy operations for primary teeth were all performed by one doctor.Results The average root preparation time was(3.70±1.19)min in group RE and(5.43±1.16)min in the PT group,which was shorter in the RE group than in the PT group(P<0.05).But the difference about endodontic interappointment pain and postoperative X-ray between the group was not statistically significant(P>0.05).Conclusion Both Reciproc nickel titanium instrument and Protaper nickel titanium instrument have the short operation time,low endodontic interappointment pain and good filling effect in root canal therapy of primary molars.The Reciproc was superior to Protaper in the cancal treatment operation time.
