Clinical Trial Summary

90-day, self-controlled, longitudinal, non-blinded clinical trial which will measure changes in clinical parameters in participants with gingivitis and Stage I or II periodontitis who apply ClōSYS® Sensitive Fluoride Toothpaste and ClōSYS® Sensitive Rinse.

Description:

The study will be conducted with 60 medically healthy participants between ages 18 to 75 years with gingival or periodontitis (Stage I or II) who are receiving routine preventive care and/or periodontal maintenance. Subjects will brush with ClōSYS® Sensitive Fluoride Toothpaste twice daily and rinse with ClōSYS® Sensitive Rinse twice daily after brushing. The primary response variables will be the Subjects' scores on the Plaque Index (PI), Gingival Index (GI) and the number of sites with bleeding upon probing (BOP). Probing depths and clinical attachment level will be assessed at baseline and 3 months. Adverse events will also be assessed and documented at each visit. In addition, Subjects will keep a usage diary documenting their daily use of the toothpaste and oral rinse and any comments or observations regarding usage or adverse events.

• Subject takes medications that may interfere with study results (eg. antibiotics, steroids, immunosuppressants, high dose aspirin (325+ mg/day), chemotherapy and/or radiation therapy for cancer).
• Subject is a current smoker
• Subject has a history of non-surgical or surgical periodontal therapy within 6 months of study participation
• Subject has Stage III or IV periodontitis, Grade B or C
• Subject is currently taking or in the past 28 days has taken another investigational drug or participated in other investigational studies that may impact study outcomes

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Changes in Modified Gingival Index (MGI)	MGI uses a rating score between 0 and 4, with 0 indicating a tooth with healthy gums and 4 the most severe inflammation. MGI scores were determined by visual exam of the gingiva on 4 surfaces for each tooth present except for third molars, for a total of 28 teeth. The total number of teeth exhibiting inflammation affecting all portions of the gingival unit (Score = 2) were noted at each visit. The total number of teeth affected was evaluated for each visit in the final analysis.; At baseline: Score range is (0-64) At 12 weeks: Score range is (0-32)	Baseline and 12 weeks
Primary	Changes in Plaque Index (PI)	The PI was recorded on all teeth except for third molars. PI was recorded on 4 surfaces of each tooth. PI uses a rating score between 0 and 3, with 0 indicating no plaque in gingival area and 3 heavy accumulation of plaque. Total score is reported.; At baseline: Score range is 9 -157. At 12 weeks: Score range is 1 -147.	Baseline and 12 weeks
Primary	Changes in Probing Depths (PD)	PD at six sites per tooth for all teeth	90 Days
Primary	Changes in Clinical Attachment Level (CAL)	CAL will be measured from the CEJ to the base of the pocket at 6 sites per tooth	90 Days
Primary	Changes in Bleeding On Probing (BOP)	Bleeding On Probing (BOP) will be recorded as a dichotomous variable (present/absent) during the periodontal examination. The percentage of sites that bleed will be calculated by dividing the number of sites with bleeding by the total number of sites.	Baseline and 12 weeks
Secondary	Adverse Events	Adverse events will be collected throughout the study	90 Days
