| Abstract | ||
| Siwak is a chewing stick used to clean the teeth and message the gum. Their routine use was shown to be associated with the reduction in severity of dental caries. This study aimed to test the effect of water Siwak extract on the microhardness and microscopic features of artificially initiated carious lesion of the outer enamel surface, in comparison to stannous fluoride and sodium fluoride. Upper first premolars were extracted and subjected to pH cycling procedure. Teeth immerged individually in 20 ml of selected agents for four minutes then rinsed by de ionized water. Agents involved were 5% and 10% water Siwak extract, 8% stannous fluoride and 0.05% sodium fluoride. Samples were subjected to Vickers microhardness test and microscopic examination before and after the pH cycling and following insertion in the agents. Water Siwak extract, stannous fluoride and sodium fluoride were found to increase the microhardness values of de mineralized enamel surfaces, this were statistically highly significant for Siwak extract and stannous fluoride (P< 0.01) and significant for sodium fluoride. However none of the mentioned agents was able to increase the micro hardness to approximate the original values of the sound enamel. Under polarized light results revealed that water Siwak extracts and stannous fluoride produce the best remineralization surface zone. Water Siwak extracts is very effective in remineralization of initial carious lesion. | ||
