Abstract
ABSTRACTBackground: Cinnamon 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 ultrasonic extract of cinnamonon the microhardness before and after artificially initiated carious lesion of the outer dentin-root surface comparedwith sodium fluoride and de-ionized water.Materials and Methods: Thirty teeth of upper first premolars extracted from 11-14 year old patients, referred fromOrthodontic Department, College of Dentistry, Baghdad University. They were randomly divided to four study groupsand one control group. After production of initial carious like lesion of outer dentin surface, the teeth were immersed,for four minutes of selected agents which were ultrasonic cinnamon extract (0.5%, 1% and 5%), sodium fluoride 0.05%and de-ionized water. Then each tooth was rinsed and storage with de-ionized water. This procedure was repeateddaily for one week. Teeth were subjected to Vicker’s microhardness and microscopic examination before and afterthe pH cycle and following the treatment with the selected solutions.Results: Ultrasonic cinnamon extract and sodium fluoride were successful in elevation of the microhardness values ofdemineralized dentin surface, this was statistically highly significant for cinnamon extract at (0.5% and 1%), andsodium fluoride 0.05%, but significant with 5% cinnamon extract concentration, while the microscopic examination ofdentin-root ground section under light microscope revealed that zone of remineralization in dentin was seen aftertreatment with all concentrations (0.5%, 1% and 5%) of ultrasonic cinnamon extract, and sodium fluoride, but itrevealed more with 0.5% cinnamon extract concentration.Conclusions: The three concentrations of ultrasonic cinnamon extract were effective in remineralization of the outerdentin-root surface; which was reflected by increase in dentin microhardness values.Key words: Cinnamon, Microhardness, Root caries.
