  Purpose
There is a need for toothpastes that more effectively remove oral plaque and prevent re-formation. The objective of this study is to map the development and resolution of clinical gingivitis using conventional clinical examination and imaging data to determine how useful imaging techniques can be for evaluating how well a toothpaste cleans the teeth

Condition Intervention
Gingivitis Device: optical measurements

Study Type: Observational [Patient Registry]
Study Design: Observational Model: Case-Only
Time Perspective: Prospective
Target Follow-Up Duration: 1 Month
Official Title: Non-Invasive Oral Biofilm Characterization

Further study details as provided by Beckman Laser Institute and Medical Center, University of California, Irvine:

Primary Outcome Measures:
  • Changes in gingival perfusion [ Time Frame: up to 6 weeks ]
    optical measurements


Estimated Enrollment: 40
Study Start Date: June 2014
Estimated Study Completion Date: June 2019
Estimated Primary Completion Date: June 2019 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Gingivitis
optical measurements
Device: optical measurements
Laser Speckle Imaging, Optical Coherence Tomography and Multiphoton Microscopy

Detailed Description:

The researcher can use imaging techniques to map changes in gingival blood flow during the development and resolution of fully reversible, early clinical gingivitis using standard-of-care clinical indices as gold standard

The researcher can use imaging techniques to map inflammatory microstructural changes in the oral mucosa including swelling, vasodilation and edema during the development and resolution of fully reversible, early clinical gingivitis using standard-of-care clinical indices as gold standard
