Comparative Analysis of Carrier-Based Obturation and Lateral Compaction : A Retrospective Clinical Outcomes Study

Abstract EN

The purpose of this retrospective study was to compare the outcome of primary endodontic treatment using a standardized cleaning and shaping technique and obturation with either lateral compaction or carrier-based obturation.

Patients received primary endodontic treatment in the predoctoral dental clinic using a standardized cleaning and shaping protocol.

All root canals were obturated using AH PlusTM sealer with lateral compaction of gutta-percha (LC) or carrier-based obturation (CBO).

A total of 205 cases met the inclusion criteria.

71 teeth in 60 patients were recalled after 2 years and evaluated both clinically and radiographically by two independent examiners.

Success was defined as a lack of clinical symptoms and a normal periodontal ligament space or reduction in size of a previously existing periapical radiolucency.

Chi-square and logistic regression were used for statistical analysis with a significance level of P<0.05.

There was no difference in success rates between cases obturated with LC or CBO (P=0.802); overall success rate was 83%.

Molars had a significantly lower success rate (53%) than premolar and anterior teeth (89%) (P=0.005), irrespective of the obturation technique used.

When a standardized cleaning and shaping protocol was used by predoctoral dental students in a controlled university setting, there was no difference in success rates between cases obturated with LC or CBO.
