Application of intraoral scanner in the evaluation of oral health for periodontal disease and peri-implantitis patients.

Application of intraoral scanner in the evaluation of oral health

20

The subjects were regularly visited the hospital for maintenance of periodontal disease and peri-implantitis. Total 20 subjectes (67.4:13.6 yes old), 7 male (64.3:19.1 years old) and 13 female (69.1:8.9 years old).

The pace of enrollment was slightly slower than initially expected, so the patient recruitment period was extended. Observation was carried out as originally planned, and no changes to the implementation period were necessary. Since multiple measurements were performed over a set period, five patients were unable to attend the hospital due to their own circumstances, leading to their withdrawal.

No adverse events were observed during the study.

In this study, the discrepancy rate between the IOS and a digital camera:control was examined by measuring the plaque staining area ratio. The results showed that IOS measurements were slightly higher. As a secondary evaluation item, a comparison test was conducted with PCR values:compared with visual inspection and blue staining solution:compared with red staining solution in IOS images. In measuring PCR values, IOS measurements were found to be higher than visual measurements. In the comparison using blue staining solution, no difference was observed between blue and red staining solutions.

It was possible to detect plaque stained areas using the intraoral scanner. The deviation rate results showed that the sharpness was slightly lower than in digital camera images. In PCR measurement, areas that could not be seen directly could be observed on the monitor, which gave a higher value. The question sheet also showed that oral hygiene instruction using the intraoral scanner was easier to understand than conventional methods.
