These authors contributed equally to this work.Background: To evaluate the efficacy and safety of oral irrigator (OI) in controlling dental plaque and gingivitis. Methods: Ninety participants diagnosed with gingivitis were randomly assigned to two groups, given a toothbrush combined with OI (WaterPikPeriodontal disease is a common disease that may bring severe implications for oral and systemic health and negatively impact the patient’s quality of life [Compared with manual floss, oral irrigators (OIs) could be potential interdental cleaning devices. OIs, introduced to the public in the 1960s, are generally designed to remove soft debris and unattached plaque through the mechanical action of a pulsating stream of water [Except for efficacy, less attention has been given to the safety of OIs, especially those with maximum pressures of 100 Psi. Oral tissue assessments and participants’ diaries are the primary methods to assess the safety of OIs [This study aimed to investigate the efficacy and safety of OIs with broader and adjustable pressure settings in managing dental plaque and gingival inflammation for patients with gingivitis during 12 weeks of follow-up. It is hypothesized that, compared to manual toothbrushing only, this OI as an adjunct would improve plaque and gingival inflammation-related indices in patients with gingivitis without causing serious adverse events and pain and dentin hypersensitivity symptoms.
