Abstract:
Introduction: Zn maintains greater enamel surface-zone porosity, facilitating
diffusion of Ca, P and F into the carious lesion; allow more subsurface
remineralization to take place. Thus, it has the potential to influence
both demineralization and remineralization. This study investigated the
efficacy of fluoride and zinc toothpaste on enamel caries of permanent
teeth in vitro.
Methods: Smooth surfaces of 60 sound extracted premolars were coated
with a nail varnish leaving a 4x4 mm window on the buccal and lingual
surface of each tooth. The teeth were immersed in demineralizing solution
for 72 hours at room temperature, to create an early enamel lesion.
The crowns were cut from the roots. The crown samples were further
sectioned into two halves in mesio-distal direction along the central fossa.
Specimens were randomly divided into two groups (I and II) (n=60),
group I; was treated by daily brushing with fluoride and zinc tooth paste
and group II; was treated with fluoridated toothpaste for 4 weeks. A scoring
system was used for SEM assessment.
Results: In the comparison between the two groups indicated better results
for group I (P = 0.0001).
Conclusions: Zinc and fluoride toothpaste has better effect on remineralization
of subsurface lesion due to the presence of zinc.
