Primary

Measure	Time frame
The association between periodontal inflammatory status (PISA value) and oral function, particularly maximum tongue pressure	—

Secondary

Measure	Time frame
Association between periodontal inflammatory status (PISA value) and nutritional status (nutrient intake assessed by BDHQ) Association between periodontal inflammatory status and other oral functional parameters (bite force, masticatory performance, tongue-lip motor function, and swallowing function) Association between past SPT attendance (duration and intervals) and current oral functional parameters as well as periodontal inflammatory status	—
