ABSTRACT
The aim of the study. To compare the long-term results of various methods of surgical treatment of root cysts of the jaws based on the data of cone-beam computed tomography.
Objects and methods. The study included 60 patients with a diagnosis of “root cyst of the jaw” (ICD-10. K 04.8). The treatment plan included CBCT of the maxillofacial region, endodontic treatment of causal teeth, cystectomy with root apex resection, intraoral radiography on the day of surgery, and repeated CBCT 1, 2, and 3 years after surgical treatment.
Results and discussion. In the first study before surgery between the groups, there was no statistical significance of differences in the size of the bone defect: 10.5 (9.7–12.3) mm in group 1 and 10.3 (9.0–11.7) mm in 2nd group. The Hounsfield index values were also comparable in the groups: 101 (79–132) mm and 104 (81–141) mm, respectively. During the re-examination in 1–3 years after the operation, there were found differences in the groups. In patients of the 1st group, there was a lack of statistical reliability of the size of bone defects before surgery – 10.5 (9.7–12.3) mm and after surgery 10.0 (9.3–11.5) mm, p = 0,59. In patients of the 2nd group, the results of measuring the bone defect showed a statistical significance of the differences before and after treatment of 10.3 (9.0–11.7) mm and 7.9 (7.0–8.7) mm, p = 0,005. In addition, the comparison of the results of the 1st group 10.0 (9.3–11.5) mm with the results of the 2nd group 7.9 (7.0–8.7) mm also indicated the presence of statistical significance of the differences.
Conclusion. Thus, based on the analysis of the results of CBCT of the maxillofacial region in dynamics, it can be concluded that the method of endocortical fixation of resorbable membranes is superior in comparison with the standard technique. CBCT data can reliably track the dynamics of the stage of bone tissue regeneration and changes in the size of the bone defect at different periods of observation of patients.
