Clinical and Radiographic Outcomes of Apical Surgery: A Clinical Study.

BACKGROUND

Endodontic treatment is usually indicated when teeth with periapical lesions are encountered. However, sometimes root canal treatment results in failure. In that case, one of the treatment choices is retreatment by an orthograde approach. Surgical endodontic therapy is also an alternative to preserve the tooth. Various techniques have been suggested in the literature which has more predictable results. The introduction of modern surgical techniques have enhanced the results of apical surgery procedures. Operating microscopes, magnifying loupes, microinstruments, ultrasonic tips, and biologically acceptable root-end filling materials (such as MTA and SuperEBA) have been introduced to this field with the modern technique, thus the success rates of modern apical surgery has increased significantly.

OBJECTIVE

The aim of the present study was to evaluate the clinical and radiographic outcomes and periotest values of apical surgery treatment.

METHODS

A total of 112 teeth were included. SuperEBA and MTA were used as root-filling materials. The recorded parameters were gender, age, location of the tooth, the presence/absence of a post, coronal restoration of the tooth, previous surgical/nonsurgical treatment of the tooth, the size of periapical lesions, histopathology of periapical lesions, smoking habits. Also the periotest values were recorded.

RESULTS

The overall success rate was 88.4%. With regard to the evaluated variables, only one parameter (tooth type) was found statistically significant. Although the periotest values were decreased after 6 months compared to immediately postoperative measurements, the values were still significantly higher than preoperative measurements.

CONCLUSION

In this study, apical surgery performed with the modern instruments has significantly successful results with 88.4% success rate.
