Background: Clove has a long traditional in use as a popular mouthwash, breath freshener and food flavoring, in
addition to its medical benefits. The purpose of this study was to test the effect of water extract of clove on the
microhardness of artificially initiated carious lesion of the outer enamel surface compared with sodium fluoride and
de-ionized water.
Materials and Methods: Thirty-one teeth of upper first premolars extracted from 11- 14 year old patients, referred from
Orthodontic Department, College of Dentistry, Baghdad University. They were randomly divided to four study groups
and one control group. After production of initial carious like lesion of outer enamel surface, the teeth were
immersed, for four minutes of selected agents which were water clove extract (1%, 5% and 10%), sodium fluoride
0.05% and de-ionized water. Then each tooth was rinsed and storage with de-ionized water. This procedure was
repeated daily for one week. Teeth were subjected to Vicker’s microhardness and microscopic examination before
and after the pH cycle and following the treatment with the selected solutions.
Results: water clove extract and sodium fluoride were successful in elevation of the microhardness values of
demineralized enamel surface, this was statistically highly significant for clove extract at (1%, 5% and 10%), and
sodium fluoride 0.05%, while the microscopic examination of enamel ground section under light microscope
revealed that zone of remineralization in enamel was seen after treatment with all concentrations (1%,5% and10%) of
water clove extract, and sodium fluoride, but it revealed more with 0.05% sodium fluoride and 5% clove extract
concentration.
Conclusions: The three concentrations of water clove extract were effective in remineralization of the outer enamelsurface;
which was reflected by increase in enamel microhardness values.
