Abstract :

Objectives: This invitro study assesses the effectiveness of topical fluoride varnish are preferable for the safety of overdenture abutments from acid challenges.

Methods: Freshly Extracted Twenty caries–free Permanent teeth were sectioned and prepared simulating overdenture abutment preparations. Teeth were randomly divided into four groups of 5specimens each. After that all teeth specimen groups were received the assigned fluoride treatment except control group. Teeth were then placed in a cycle of demineralization and remineralizationbesides that teeth were sectioned at 10μm buccolinguallywith a hard tissue microtomeand evaluated under Polarized light microscope.

Results: The lesions in the control group (A) were homogeneous while there was much variation in depth in the fluoride treatment groups. The remineralization bands were detectable in all groups, and it was particularly evident in weekly MI varnish (weekly)Group C.

Conclusion:With the invitro condition chosen, daily application of MI Varnish is the most efficient and useful treatment of products tested for the improvement of remineralization & preventing demineralization of overdenture abutments.
