Overview

Brief Summary

Qualified subjects will be enrolled and randomized to either one of the two study groups described above based on their initial modified gingivitis and plaque scores. Subjects will be instructed to use the products according to the instructions provided. Subjects will return to the dental office for evaluation after two weeks, six weeks and three months of product use. All subjects will be followed for adverse events throughout the study

Arms & Interventions

Test 1 mouthwash

Experimental

After brushing in the morning and in the evening, 20 ml of mouthwash shall be used for each rinsing, 2 times daily (morning and evening) for 30 seconds each time. No further rinsing with water shall be occurred after each mouthwash rising. Each qualified subject will follow this specific application for 3 months

Intervention: cetylpyridinium chloride (CPC), zinc lactate and sodium fluoride Mouthwash (Drug)

Test 2 mouthwash

Active Comparator

After brushing either in the morning or in the evening, 20 ml of the mouthwash shall be used for each rinsing, 2 times daily (morning and evening) for 30 seconds each time

Intervention: sodium fluoride Mouthwash (Drug)

Outcomes

Primary Outcomes

Modified Gingival Index

Time Frame: baseline, 2 week, 6 week & 3 month

A Modified Gingivitis Index score from 0 to 4 will be assigned by the examiner to all tooth surfaces. In regards to the scale, lower number is a better outcome.

Saxton Bleeding Index

Time Frame: baseline, 2 week, 6 week & 3 month

Gingival bleeding is assessed 30 seconds after probing; a score of 0 represents an absence of bleeding. a score of 1 is given if bleeding is observed within 30 seconds after probing and a score of 2 is given if bleeding is observed immediately on probing

Modified Quigley-Hein Plaque Index

Time Frame: baseline, 2 week, 6 week & 3 month

Modified Quigley-Hein Plaque Index score of 0 to 5 will be assigned to all scoreable disclosed tooth surfaces. In regards to the scale, lower number is a better outcome.

Modified Gingival Index

Time Frame: baseline, 2 week, 6 week & 6 month

A Modified Gingivitis Index score from 0 to 4 will be assigned by the examiner to all tooth surfaces. In regards to the scale, lower number is a better outcome.
