A Retrospective Study of Root Canal Therapy in Non-vital Primary MolarsStallaert, Karen M. 20 December 2011 (has links)
Purpose: This retrospective study was performed to assess the clinical and radiographic success rates of a non-vital formocresol and zinc oxide eugenol (ZOE) primary molar root canal therapy (RCT) technique. The effects of this treatment on the permanent successors and on exfoliation times were also investigated.
Methods: The study included 161 patients with 211 primary molars treated by RCT by a single operator in a private pediatric dental office in the Toronto area.
Results: A clinical success rate of 90.0% and a radiographic success rate of 77.3% were obtained. Enamel defects were found in 6.8% of permanent successors and in patients who were significantly younger at the time of root canal therapy treatment (p = .001). Treated molars exfoliated on average 5.8 months sooner than contralateral teeth (p<0.001).
Conclusions: Formocresol and ZOE RCT is a viable treatment for necrotic primary molars and yielded very high clinical success rates with moderate radiographic success rates.

Comparison of time taken and breakage of six different endodontic systems to prepare molar teeth.Brittain, Roger January 2006 (has links)
The purpose of this study was to determine duration time, breakage and apical displacement, whilst using six different endodontic filing systems to prepare molar teeth. A total of 96 molar teeth were used in the study, divided equally, ie 16 teeth per system selected randomly, totalling 48 canals per system. A standardised access cavity was prepared for all the teeth before selection. The canals were filed according to the manufacturers&rsquo / guidelines. The result showed that PROTAPER® / , K3&trade / and the combination of: HERO Shaper® / , HERO Apical® / and Endoflare® / (Referred from hereon as HERO System for convenience) were statistically faster than PROFILE® / and FlexMaster® / , which were in turn faster than AETTM. Although breakage did occur in K3&trade / and HERO System this was not deemed statistically significant. Apical displacement occurred in the form of Type 1 in the AETTM, PROFILE® / and HERO System, but once again this was not statistically significant. It was concluded that more aggressive cutting features such as a positive rake<br />
angle, pyramidal shaped tip, progressive taper and absence of radial lands, if present, could have enabled K3&trade / , HERO System and PROTAPER® / to have faster times, and in addition these features did not compromise these systems with regard to apical foramina transportation and breakage.
