Pigmenting effect of a new mouth-rinse containing PropolEffect

ABSTRACT
Aim of the work.
The aim of this study was the in vitro evaluation of the staining properties of a mouth-rinse containing Propoleffect®.
Materials and methods.
60 anterior bovine teeth were used, randomly divided in three groups (n=20) and immersed in a Propoleffect®-based mouth-rinse (group A), a 0.12% chlorexidinebased mouth-rinse (group B) and artificial saliva (control group C). Groups A and B were immersed in the mouth-rinse for 2 minutes, rinsed under tap water and stored in artificial saliva.
The immersion in the mouth-rinse was repeated every 12 hours for 28 days. Colour of all teeth was analysed in blind before treatment and at 1, 3, 7, 14 , 21 and 28 days after mouth-rinse immersion.
Tooth colour was assessed using a spectrophotometer based on the CIE-Lab system and a VITA colour-shade guide.
Results.
Both mouth-rinses tested did not produced significant discolorations of enamel.
Conclusions.
Based on the data of this in vitro study the Propoleffect®-based mouth-rinse seems not to cause tooth staining after 28 days.

KEY WORDS: Propoleffect®, chlorexidine, mouth-rinses, tooth discolorations.
