Conditions

Plaque Induced Gingivitis

Outcome Measures

Primary Outcomes (2)

• To assess the effectiveness of the test product in terms of change in plaque deposition

  By using Turesky Modification of the Quigley-Hein Index by Dentist or Dentist trained evaluator.

  Before and after usage of test product at T30 mins on Day 01, Day 15 (±2 days), and Day 30 (±2 days)

• To assess the effectiveness of the test product in terms of change in plaque induced gingivitis

  By using Loe \& Silness Gingival Index by Dentist or Dentist trained evaluator.

  Before and after usage of test product at T30 mins on Day 01, Day 15 (±2 days), and Day 30 (±2 days)

Secondary Outcomes (1)

• To assess the improvement in product perception questionnaire

  Baseline prior to usage of test product and on Day 01, Day 15 (±2 days), and Day 30 (±2 days)

Other Outcomes (1)

• Safety assessment by examined of oral soft tissues (tongue, hard and soft palate, gingivae, mucobuccal folds, inner cheeks, sublingual areas) and hard tissues, including dental restorations.

  At baseline Day 01 (±2 days), Day 15 (±2 days), and Day 30 (±2 days)
