Evaluación comparativa de la endodoncia guiada por estática frente a la endodoncia a mano alzada en dientes...

The present study aimed to compare the use of conventional freehand access cavity preparation with the static-guided (SG) endodontic technique in terms of its ability to locate and negotiate root canals, iatrogenic errors (perforations), and the amount of tooth structure loss while treating single-rooted traumatized teeth with pulp canal calcifications (PCC).

This randomized clinical trial was registered in the Clinical Trial Registry of India (https://ctri.nic.in, CTRI/2024/01/061580). A total of 30 patients with traumatized teeth exhibiting calcified root canals were included in the study. The patients were randomly divided into two groups as follows: SG endodontic technique and conventional freehand technique. Following the completion of the treatments, the cases were evaluated as either successful (canal located) or failed (perforation or canal not located). In addition, the amount of removed tissue was calculated on the postoperative radiographs using ImageJ software. Chi-square and Mann-Whitney U tests were performed to analyze the data (P = 0.05).

In the SG endodontic group, canals were located in all teeth, while in the conventional freehand approach, 13% of cases reported failure to locate root canals. Tissue loss was significantly lower in the SG approach compared to the conventional freehand approach (P < 0.05).

The conventional freehand technique caused three times more tooth tissue loss compared to the SG endodontic approach. There were no failed cases in the SG endodontic technique group, and all root canals were successfully located.
