Clinical Trial Summary

A full understanding of etiology and diagnosis of peri-implant diseases is crucial for finding effective treatments for these diseases that are more widely accessible to dentists. Several treatment protocols for peri-implant diseases have been proposed, but no gold standard has been established to date. Thus, the purpose of this study is to analyze efficacy of stabilized chlorine dioxide as a chemical adjuvant for treatment of peri-implant mucositis in a non-surgical treatment protocol with a 3-month follow-up.

Description:

Fifty individuals with peri-implant mucositis will be identified to participate in this study and randomized into two groups to analyze clinical parameters and results of this study: 1) test group (stabilized chlorine dioxide rinse) and 2) control group (placebo). Each group will be associated with periodontal basic therapy.

Treatment Protocol After inclusion of the patients, medical history and initial examination are performed, patients will be randomly divided into the following two groups: 1) test (stabilized chlorine dioxide rinse associated with periodontal basic therapy); and 2) control (placebo associated with periodontal basic therapy).

Periodontal basic therapy will consist of oral hygiene instruction, motivation, retentive factor removal, and an adaptation of the protocol of full-mouth scaling and root planing (stabilized chlorine dioxide mouthwash will be used). Plastic currets are used to instrument the implants and metal currets to instrument teeth. Immediately after instrumentation, chemical solutions of chlorine dioxide or placebo will be dispensed to the subjects.

The subjects will follow their normal oral-hygiene procedures with the addition of using the study rinse toothbrush and toothpaste provided to them.

• No radiographic evidence of bone loss beyond the first two threads of the implant

Exclusion Criteria:

• Patients treated with systemic antibiotic therapy or periodontal/mechanical/local delivery therapy within 12 weeks prior to study entry and throughout the study duration.

• Patients chronically (i.e. two weeks or more) treated with non-steroidal anti-inflammatory drugs (NSAIDs) or any medications know to affect soft tissue condition (excluding treatment of Acetylsalicylic acid = 100 mg/day).

• Patients with uncontrolled diabetes, of any type, and/or patients with HbA1c test value >7.5% dated 3 months prior to the screening visit.

• Patients receiving radiation therapy to the head and neck area and/or receiving immunosuppressive therapy.

• The presence of any medical or psychiatric condition or any other condition that, in the opinion of the Investigator, could affect the successful participation of the patient in the study.

• Drug and alcohol abuse.

• Patient participates in any other clinical study 30 days prior to the start of the study and throughout the study duration.

• Subject is pregnant (based on pregnancy result) or lactating.

• Subject is a smoker, or has been a smoker within the past 6 months.

• Any other condition that may interfere with the study as judged by the PI

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Global Probing Depth	The distance measured from the base of the pocket to the most apical point on the gingival margin. Measured in mms. Over 3 mm indicates a need for periodontal therapy. Higher results mean a worse outcome.	90 days
Primary	Global Plaque Score.	The plaque index assesses the amount of dental plaque visible on the vestibular and lingual surfaces of all teeth, except the third molars. The index is calculated by dividing the number of plaque-containing surfaces by the total number of available surfaces. Values range from 0-18 with 0 being excellent and 18 poor. Higher numbers mean a worse outcome.	90 days
Primary	Modified Gingival Index (MGI)	The MGI relies on a visual assessment of gingival changes to measure the severity of inflammation. Five categories, using a 0-4 scale, score the marginal and papillary gingival tissue based on color, texture, edema, and spontaneous bleeding. 0 being normal and 4 being severe inflammation characterized by edema, redness, swelling, and spontaneous bleeding. The higher scores mean a worse outcome.	90 days
