It has been claimed that correlations exist between oral gas and periodontal disease. In this study the investigator measured oral gas with Motivation® (SN-PD21703 : Sense It Smart Corporation, Tokyo) and assessed the status of periodontal disease by PSR (Periodontal Screening Recording). The aim of the study was to determine wether it is possible to prefigure periodontal disease on the basis of oral gas measurements. Motivation® is a periodontal screening machine that measures odors, and it contains several semiconductor gas sensors. The investigators measured oral gas for three seconds in 94 patients and performed PSR as an indicator of periodontal disease status. They also tested oral gas and periodontal disease for correlations by using the artificial neural network constructed from the parameters of sensor characteristics and PSR codes. The results showed that the artificial neural network showed the advantaged prefiguration (r=0.97). PSR is an easy method to screen for periodontal disease. The results of this study, showed a high correlation between oral gas and periodontal disease, suggesting that measuring oral gas is easy and useful method for prefiguration of periodontal disease.
