Abstract

Introduction. Complex pathogenetic events during periodontal disease occur on tooth root surface. These events can cause physical and chemical changes on it. The main aim of this research was - to investigate the chemical changes on the dental cementum after laser- assisted periodontal therapy.
Material and method. Examined sample consists of 40 root surfaces from extracted teeth. All extracted teeth were in stage III and IV of periodontal disease according to the classification framework of periodontal diseases from 2018. Qualitative and quantitative chemical analysis, for each element present was done with ICP (inductively coupled plasma) with mass spectrophotometry. A control group consisted of extracted impacted teeth or teeth that were extracted for a non-periodontal reason (occlusal trauma, orthodontic therapy or prosthetic reason).
Results. Data showed statistically significant loss of calcium on the surfaces of teeth treated with laser-assisted periodontal therapy. Based on the data, root surfaces treated with laser-assisted periodontal therapy had a statistically significantly higher amount of phosphorus. The ratio of sulfur in the root surfaces where laser-assisted periodontal therapy was performed, there was no statistically significant difference for P = 0.0629. Also, there was a significant difference between the presence of iron in the control group and from teeth on which laser-assisted treatment was done.
Conclusion. There are numerous chemical changes observed after laser-assisted periodontal treatment on root surfaces compared to root surfaces obtained from healthy root surfaces.
Keywords: chemical changes, dental lasers, laser-assisted periodontal therapy, root surface
