NCT05866341

Brief Summary

The aim of this investigation is to evaluate the impact of the 14- day consumption of a nitrate-rich diet on the the extent of gingival inflammation in a cohort of periodontal aftercare patients. Recorded parameters were gingival index, plaque control record, salivary nitrate/nitrite level and vascular parameters

Masking Details
Patients were allocated using a computer-generated randomization list in blocks of six either to the test or the placebo group. Assignment to a participant number was done according to the chronological order of enrolment in the study. All therapeutic and diagnostic interventions were performed at the Department of Periodontology of the University Hospital of Wuerzburg. All examinations were performed by two experienced, inter- and intra-calibrated periodontists not being involved in patient assignment and hand out of the experimental juices respectively.
