Comparative Analysis Of The Clinical Effect Of Root Filling Between Continuous Wave Of Condensation Technique And Cold Lateral Condensation Technique

Objective In this study,continuous wave of condensation technique and cold lateral condensation technique are compared in terms of filling quality,frequency of obturation of lateral branch of root canal and postoperative pain,to explore these techniques filling effect is more likely what view in our hospital.Methods:Collected 65 live pulp premolars from 65 patients which need for root canal treatment.They were randomly divided into A, B two groups.Each tooth was prepared with k-files and M3 Ni-Ti files.Group A had 34 teeth forcold lateral condensation technique,and Group B had 31 teeth for continuous wave of condensation technique.Observed two methods in thefilling quality,frequency of obturation of lateral branch of root canal by X-ray,and evaluated postoperative pain by postoperative follow-up.Results:There were 1 under-filled,31 flush,2 over-filled in group A,and 0 under-filled,28 flush,3 over-filled in group B.There was no statistically significant difference between two groups(P>0.05).The ratio of the obturated lateral canals was 2.94% in group A and22.58% in group B.Significant difference was found between two groups(P<0.05).the incidence of postoperative pain when 1 day after the root canal therapy was 2.94% in group A,and 16.13% in group B.There was no statistically significant difference between two groups(P>0.05).After 7 days in the two groups were no postoperative pain.Conclusion:Through this research combining with literature review,we learn that continuous wave of condensation technique can also be high quality finish root canal filling.And can improve the efficiency of the obturation of lateral branch of root canal.It is more likely to prompt the existence of lateral branch of root canal.At the same time, it does not increase the risk of over-filled and postoperative pain.
