5. Conclusions
OIs
OIS, PLAQUE
With the limitations of the study, we conclude that OIs as adjuncts to toothbrushing are significantly more effective than toothbrushing alone in controlling plaque and improving gingival health. Its efficacy was positively correlated with irrigation pressure and the amount of plaque. Furthermore, the application of OIs was safe during the 12 weeks observation period, and with its good compliance, OIs could be effective adjunct cleaning tools.
