Objectives

Narrative objectives1

Diagnosis of periodontal disease is not suitable for health checkup projects involving more than 100 people per day, such as periodontal histology and X-rays. Saliva tests have been developed to address this problem, but they have not been widely used due to problems with diagnostic accuracy. The purpose of this study is to verify the diagnostic accuracy of a new periodontal disease risk diagnosis algorithm developed by combining quantitative salivary test values (leukocyte esterase, hemoglobin, and protein) with a quantitative PCR method that can quantify the amount of periodontal pathogens.

Basic objectives -Others

The diagnostic accuracy of a new periodontal disease risk diagnostic algorithm developed by applying absorbance measurement technology to detect periodontal pathogens using quantitative PCR and quantitative test values from saliva samples will be compared to conventional periodontal disease tests to evaluate reliability.

Assessment

Primary outcomes

Logistic regression equation with patient PISA actual values as the objective variable
The diagnostic criteria by PISA is that 100 or less is healthy, 100 to 500 is pre periodontal disease, and 600 or more is moderate periodontal disease. Therefore, PISA values obtained from each subject were logit-transformed and used as the objective variable, with PISA values of 100 and 600 as the cutoff values. The quantitative values of periodontal pathogens (Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola, and Filifactor alocis) by quantitative PCR and SiLL-Ha's hemoglobin, leukocyte esterase and protein values are placed as explanatory variables and logistic regression equations are calculated.

Key secondary outcomes

Validation of diagnostic accuracy of logistic regression equations
The diagnostic accuracy of the logistic regression equation at each cutoff value will be tested by ROC analysis to detect diagnostic accuracy (accuracy, sensitivity, specificity, positive predictive value, and negative predictive value), by AUC determination, and by Hosmer-Lemeshow method to determine the fit of the regression model.
