Abstract:
Introduction: The retrograde endodontic treatment of periapical periodontal diseases in
classical vision shows little chance of success. This is explained by the use of inappropriate tools,
inadequate visibility, frequent postoperative complications and failures that resulted in the
extraction of the tooth. This changed radically with the introduction of the microscope, of micro
tools, sonic and ultrasonic tips and plug biocompatible materials.
Purpose and Objectives: To evaluate preliminary clinical results of the use of SONIC retro
tips in retrograde endodontic treatment and estimate the surgical access to the root apex and
capacity of retrograde cavity preparation.
Material and methods: The study included 10 patients who had periapical periodontal disease at
one tooth, 10 teeth underwent apical resection. While the clinical and instrumental examination, orthopantomography and dentoparodontal radiography were made, computed tomography in case of necessity.
Results: Following clinical examination data, we have set limits of periapical pathology, the
condition of neighboring teeth, the condition of mucosa. Access to the operative field was superior
in 100% of patients. On postoperative contact radiographs, the length of retrograde obturation and
the length of resected tip were counted. During the 6 months period after surgery, 1 from 10
patients was complaning of periodical pains and there was sensibility around the root tip projection
on palpation. According to the clinical and radiographic criteria, in 9 patients have obtained good
results and only one of 10 has failed.
Conclusion: The tips simplify the surgical access to the root apex and have a good capacity
of preparation. Preliminary clinical results indicate excellent progress at 6 months postoperatively.
With these tips intra and postoperative aspects in apical resection are considerably improved for
doctors and patients.
