Polishing vs Hydrogen Peroxide: Effect on DIAGNOdent Readings in Stained Fissures
Sponsor: Özlem Erçin Sultanzade
Summary
This study compared two methods of cleaning stained pits and grooves (fissures) on the chewing surfaces of back teeth before measuring them with a laser fluorescence device (DIAGNOdent), which is used to help detect early tooth decay. In the same patients, one side of the mouth was treated with mechanical polishing using a prophylaxis paste, while the other side was treated with a 35% hydrogen peroxide gel. The study measured whether either cleaning method changed the device's readings, and if so, by how much. The results showed that the readings increased after both procedures, but the increase was larger after polishing than after hydrogen peroxide application. These findings may help clinicians better interpret DIAGNOdent readings after cleaning stained teeth.

Interventions
Mechanical Polishing with Fluoride-Free Prophylaxis Paste
Application of a fluoride-free prophylaxis paste (Cleanic, Kerr, Salerno, Italy) to the occlusal fissure area using a polishing brush attached to a micromotor operating at 10,000 rpm, for 30 seconds with light pressure using circular movements, followed by water spray rinse and air drying.
35% Hydrogen Peroxide Application
Application of an in-office bleaching agent containing 35% hydrogen peroxide (Whiteness HP, FGM Dental, Brazil), prepared per manufacturer's instructions (3 drops peroxide, 1 drop thickener), covering the stained fissure areas for 15 minutes, followed by aspiration, water rinse, and air drying.
