    Abstract:
    AIM: To compare the clinical and microbiological outcome of the 1-h ultrasonic debridement of chronic periodontitis patients (CPP) with and without frequent sessions of oral hygiene reinforcement. METHODS: Clinical measurements and subgingival plaque were collected from 44 CPP at baseline, 3- and 6-months. The control group received a single session of 1-h full-mouth ultrasonic debridement, while oral hygiene instructions (OHI) were reiterated over four visits. In the test group, OHI were limited in the 1-h treatment session. At 3-months, both groups received additional debridement and OHI. The "Checkerboard" DNA-DNA hybridization technique quantified Porphyromonas gingivalis, Tannerella forsythia and Treponema denticola in plaque. RESULTS: At three months, smaller reductions in plaque and bleeding indices, and in P. gingivalis numbers were noted in the test group, while these differences disappeared at six months. After the 3-month re-treatment visit, the test group presented with a greater probing pocket depth (PPD) reduction. Plaque negatively affected PPD in a similar manner after both treatment approaches. CONCLUSIONS: Lack of oral hygiene reinforcement in the 1-h full-mouth debridement resulted in higher plaque and bleeding scores and numbers of P. gingivalis at three months; professional removal of dental biofilm every three months is beneficial in subjects with compromised plaque control.
