Patients included in the study will undergo a thorough clinical examination aiming at collecting all the data desired: periodontal parameters of Probing Pocket Depth (PPD), presence of recession of the gingival margin (Rec) and full mouth plaque score (FMPS) will be recorded on six sites/tooth by a single calibrated examiner using a University of North Carolina (UNC) 15-mm periodontal probe by a calibrated examiner blind to group allocation.~Gingival index (GI) and angulated bleeding score (AngBS) will be recorded at four sites/tooth.~For GI the following scale will be used:~0 normal appearance of gingiva, no bleeding, no inflammation;~slight change and moderate edema with slight change in texture, no bleeding, mild inflammation;~redness hypertrophy, or edema and glazing, bleeding on probing, moderate inflammation;~marked redness, hypertrophy, or edema, ulceration, spontaneous bleeding, severe inflammation.~For AngBS the following scale will be used:~0: no bleeding;~bleeding upon probe stimulation;~spontaneous bleeding~Consequently, interdental plaque score (IPS), interdental gingival index (IGI), and interdental angulated bleeding score (IAngBI) will be calculated.~Patients will be followed through a five-week period. The timepoints will be the following: T -7 (oral hygiene instructions), T0 (professional supragingival scaling and polishing), T14, T28.
To determine the efficacy of four different oral hygiene protocols involving adjunctive interdental cleaning devices in periodontal patients in terms of plaque and gingival inflammatory scores.
