Saliva obtaining: The patient was asked to sit upright and tilt his/her head forward to collect saliva samples. İn this way, unstimulated saliva was allowed to accumulate in the floor of the mouth. The accumulated saliva was collected in a sterile container. It was then transferred to a propylene tube. The tubes were centrifuged and the clear part at the top of the tube was taken with a sterile syringe and transferred to a different propylene tube with 0.5 ml in each tube. Tubes were stored at -80ºC until the day of analysis.
The aim of this study was to determine the effect of orthodontic treatment with aligner on changes in osteoprotegerin (OPG) and receptor activator of NF-κB ligand (RANKL) levels in saliva samples and to investigate the possible relationship between periodontal clinical parameters. Materials and Methods: A total of 25 (n=25) saliva samples were taken from systemically healthy non-smoking individuals who were planned to receive orthodontic treatment with aligner before treatment. Whole mouth clinical periodontal measurements including probing depth (PD), clinical attachment level (CAL), bleeding on probing (BOP), gingival index (GI) and plaque index (PI) were also recorded and repeated at 1 and 3 months. Enzyme-linked immunosorbent assay (ELISA) was used to determine OPG and RANKL levels in biological samples.
