Arms & Interventions

Test Group

Active Comparator

Subjects will be instructed to brush their teeth twice daily for two minutes each time with the toothpaste and toothbrush provided. After brushing, subjects will swish with 15 ml of mouthrinse for 30 seconds.

Intervention: Test Mouthrinse (Other)

Control Group

Placebo Comparator

subjects will be instructed to brush their teeth twice daily for two minutes each time with the toothpaste and toothbrush provided. After brushing, subjects will swish with 15 ml of mouthrinse for 30 seconds.

Intervention: Control Mouthrinse (Other)

Outcomes

Primary Outcomes

Improvement of gum health as measured by the Gingival Index (Löe 1967) between the study groups.

Time Frame: 6-month period

Four areas of the tooth (buccal, lingual, mesial, and distal surfaces) will be assessed. Each site is assigned a score from 0 to 3 based on clinical observation: 0 indicates normal gingiva and 3 denotes severe inflammation with marked redness, edema, ulceration, and a tendency toward spontaneous bleeding.

Secondary Outcomes

  • Plaque scores as measured by the Plaque Index (Turesky et al. 1970) between the study groups(6-month period)
