About this study

Patients will be assigned for two clinical appointments, the first visit is for baseline charting, probing depth will be recorded on six sites per implant, using a standardized periodontal probe and the presence or absence of bleeding will be recorded. Disclosing tablets will be utilized to

Confirm the presence or absence of plaque around teeth and the implant. Patients (Group A) will be given a water floss, with verbal and written instructions to use the water floss, twice daily for 2 minutes, along with brushing, while Group B will be instructed to brush with a manual brush alone, twice daily for 2 minutes. After two weeks, in the second visit, the implant site is re-evaluated to monitor the outcomes.

Treatment and study plan

Water Flosser

Device

Water irrigation device

Tooth brush and string floss

Device

The control group will use the toothbrush and the regular string floss.

Primary outcomes

  1. Bleeding on Probing

    Time frame: 2 and 4 weeks

    The disappearance of bleeding upon probing with the University of North Carolina-15 mm (UNC-15) periodontal probe. It is done at the same time as probing the pocket depths. It is done at six sites per implant-presence of bleeding = 1, absence = 0 -at each site.

  2. Plaque Index of Silness and Loe

    Time frame: 4 weeks

    Score Description 0 No plaque 1 A thin film of plaque adhering to the free gingival margin and adjacent area of the implant; not visible to the naked eye but detectable by probe 2 Moderate accumulation of soft deposits visible to the naked eye within the gingival pocket and/or on the implant and gingival margin | 3 Abundant soft matter within the gingival pocket and/or on the implant and gingival margin |

Secondary outcomes

  1. Probing Pocket Depths (PPD)

    Time frame: 4 weeks

    The PPD will be recorded at baseline visit using the UNC-15 periodontal probe, at 2 weeks, and at 4 weeks. Pocket depths around implants should usually be around 1-4 mm. Pockets that are deeper than 4 mm or are 4 mm or less but with bleeding will be recorded as abnormal.
