Abstract
Aim: The aim of this in vitro study was to evaluate the effect of chicken egg shell powder solution (CESP) on the dental erosion produced by Coca Cola drink in permanent teeth. Material and methods: Thirty extracted human incisors were collected for this study purpose. After extraction all the specimens were cleaned and sectioned longitudinally resulting in 60 samples from a total of 30 tooth samples. All samples were randomly assigned to the following three groups. Group 1: Untreated group, Group 2: Demineralization by soft cola drink (4 cycles of 2 minutesâ immersion at 6 hoursâ interval), Group 3: Demineralization by soft cola drink (4 cycles of 2 minutesâ immersion at 6 hoursâ interval) followed by 7 daysâ immersion in CESP. For surface roughness assessment images were taken from AFM. The root means square roughness (Rrms) was calculated from the AFM images. The differences in the mean roughness values between the three groups were analyzed by Anova and Tukeyâs post hoc test. Results: One way Anova analysis revealed a statistically significant differences with p-value of 0.00, between the mean roughness values of three groups. Tuckeyâs post hoc test revealed that there is a statistically significant difference (0.158±0.012) between the surface roughness of Group 2 and Group 3 as well as between Group 1 and Group 3(0.085±0.012) with a p-value of 0.00, indicating that following treatment by CESP the mean roughness values decreased significantly. Conclusion: CESP reduces the surface roughness of all treated teeth samples giving encorughment to the protective effect of CESP againts erosive enamel loss.
Highlights
The paradigm of modern dental practice is gradually moving towards the concept of minimal invasion dentistry(MID) which is a conservative philosophy that mainly emphasizes upon early detection of carious lesions, remineralization of tooth surfaces and preservation of surrounding tooth structure [1,2]
Tapping mode AFM (TM AFM) images were used to study the topographic features of polished tooth surfaces and to show net differences between exposed and un exposed enamel surfaces
The protective effects of chicken egg shell powder solution on enamel was compared with samples treated with demineralizing solution and the results showed a statistically significant difference (0.158±0.012) with a p value of 0.00 indicating the effectiveness of remineralizing effect of Chicken Egg Shell Powder Solution (CESP) on enamel surfaces
Summary
The paradigm of modern dental practice is gradually moving towards the concept of minimal invasion dentistry(MID) which is a conservative philosophy that mainly emphasizes upon early detection of carious lesions, remineralization of tooth surfaces and preservation of surrounding tooth structure [1,2]. Since enamel lacks an inherent ability to repair itself if affected by abrasion, fracture or caries, the rebuilding of early, superficial enamel layer loss depends heavily on the composition of saliva as well as on tooth pastes and creams containing alloplastic materials such as calcium or fluoride [8]. Modern tooth pastes/creams/gels containing sodium fluoride or tri calcium phosphate have been considered as the most effective source of in organic ions required for enamel remineralization [9]
