301 - Digital Plaque Monitoring: Brushing with Magnesium Containing Toothpaste.

Abstract:

Purpose: This study aimed to evaluate the reliability of a 3D-image analysis for quantifying dental plaque by digitally analyzing color 3D-images obtained from an intraoral-scanner, intraoral camera images and comparing the results with clinical examination findings before and after brushing with a magnesium (Mg) containing toothpaste.

Methods: A 9-year-old-boy with a high plaque score according to the Turesky Modified Quigley-Hein-Plaque-Index (TMQHPI) was evaluated. Plaque was disclosed (Tri Plaque ID Gel, GC, USA) and recorded before and after brushing with a Mg containing toothpaste (R.O.C.S Active Mg; Russia) using standardized intraoral-camera images (EOS 760D, Canon Inc., Japan) and a 3D-intraoral-scanner (iTero Lumina, Align Technology, USA). Digital plaque quantification was conducted using software (Image J) by calculating the plaque area-to-tooth surface area percentage (P%) and Digital Area (pixel).

Results: At baseline, TMQHPI scores were 4.5 for 3D intraoral scanner images and were slightly higher compared with intraoral camera images (4.0). The plaque-covered area percentage was 52% for intraoral-camera-images. After brushing with the Mg-containing toothpaste, TMQHPI scores decreased to 1.75 for intraoral camera images and to 2.0 for 3D intraoral scanner images. The percentage of plaque-covered area decreased to 19.7%.

Conclusion: The Mg-containing toothpaste formulation effectively reduced dental plaque. Moreover, its efficacy can be reliably combined clinical evaluation, digital-image-analysis, and 3D-scanning, supporting the use of digital plaque monitoring as a suitable tools in pediatric dental patients.
