Design outcomes

Primary

Measure	Time frame
Bleeding of the gingiva on probing as an indicator of oral health	—

Secondary

Measure	Time frame
- Number of self-reported pain complaints. Pain is defined as a confirmative answer to the question: Have you had any pain or discomfort from your teeth since the last visit? Pain provoked by warm, cold, sweet, sour or tenderness to touch or chewing. - Presence or absence of dental plaque per site and dental plaque coverage percentage (mS&L) to provide a general impression of the oral hygiene (good: plaque coverage 60%); - Dental pocket probing depth (in mm) and gingival recession (in mm) to determine the total amount of attachment loss resulting in the presence or absence of clinical attachment loss and the Periodontal Inflamed Surface Area (PISA); - Presence or absence of aphthous lesions, mucosal ulcerations or other forms of mucositis; - Presence or absence of peri-oral inflammation (herpetic ulcers or angular cheilitis) - Presence or absence of old / pathogenic (red fluorescent) dental plaque and the coverage percentage of red fluorescent dental plaque (RFP) using a dedicated single-lens-reflex-camera (Quantitative Light-induced Fluorescence; QLF-camera) and cheek retractors 35; - Number of decayed, missing or filled surfaces (DMFS); - Clinical Oral Dryness Score General health - General health questionnaire (an extensive questionnaire at visit 1 and 5 short questions during follow-up visits); - Abdominal girth (change over time from baseline till the end of the mission); Sleep, stress, lifestyle and diet - Questionnaire on general living and sleeping habits: score of sleeping habits - Validated Perceived Stress Scale, questionnaire in Dutch (PSS.nl) - Smoking habits (smoking (yes/no) and in pack/years) etc.; - Physical activity at home and during the mission; - Food and drinks intake frequency questionnaire; Oral effects of stress - Presence or absence of arthrogenic or myogenic temporomandibular joint problems using a validated questionnaire on TMJ pain and headache.
