Retrospective evaluation of occlusal adaptation of stainless steel crowns applied under deep sedation

Background: The objective of this study was to retrospectively assess the occlusal adaptation, marginal adaptation, and other clinical pathologies of stainless steel crowns (SSCs) performed under deep sedation. Methods: Patients who received SSCs under deep sedation between January 2022 and January 2023 and underwent clinical follow-ups, along with photographic/radiographic evaluations if available, at the 1st week, 1st, 3rd and 6th months, were planned to be included in the study. Furthermore, patients were included in the study if they were evaluated for marginal adaptation of SSC, occlusal adaptation of SSC, fracture or decementation of SSC, abscess/fistula formation, and sensitivity to palpation or percussion during clinical follow-ups. These findings were recorded retrospectively. Accordingly, 24 patients who met the specified criteria were included in this study. The data was analysed with Wilcoxon Signed-Rank test (significance level was set at 0.05). Results: In the first week, successful occlusal adaptation (SOC) was observed in 83.33% (n = 20) of the cases. Also, no other clinical failures or marginal inadaptibility were found in any patient. In the marginal adaptation and clinical success, there was no statistical difference between the examination periods in terms of the number of successful cases (p = 1.000), while the successful cases in the occlusal adaptation evaluation in the first week was statistically lower than those who were successful in further examination periods (p = 0.046). Conclusions: Within its limitations, this study demonstrated that the occlusal adaptation of SSCs placed under deep sedation was acceptable even in the immediate postoperative period. The results are thought to be influenced by the adaptive masticatory system of children. Therefore, it was suggested that acceptable occlusal harmony could be achieved by referencing the adjacent and opposing teeth during SSC placement. Nonetheless, further clinical studies are required to validate these findings.
