Digital quantification of soft tissue volumetric changes after scaling and root planning.

BACKGROUND

Monitoring the outcome and evolution of periodontitis treatment requires analyzing changes in the periodontium. However, traditional methods for analyzing volumetric changes in periodontal soft tissues have limitations due to their invasiveness or inaccuracy. The aim of this study was to measure the volumetric changes in periodontal tissues following scaling and root planing treatment using digital methods, such as the superimposition of pre- and post-treatment STL files Material and

Methods

The study started with an initial periodontal examination and intraoral scanning. Periodontal treatment was then performed, and at the one-month re-evaluation, the same records were repeated. Finally, the clinical data and STL files of pre- and post-treatment scans were compared.

RESULTS

in terms of clinical data, there was a mean decrease in probing depth of 0.34 ± 0.54 mm and a significant decrease in bleeding rate. Digital measurements showed a mean loss in height of 0.196 ± 0.188 mm and width of 0.344 ± 0.338 mm.

CONCLUSIONS

Quantifying periodontal tissue changes after scaling and root planing was possible by superimposing STL files. Post-treatment gingival tissue shrinkage occurred in both height and width, which was not visible with conventional recordings.
