Objective: Multiple etiological factors contribute to the process of erosion and destruction of enamel. Among which, carbonated soft beverages and energy drinks are the most aggressive extrinsic causes. The consumption of milk whether bovine or plant based highly contributes to the remineralization process.Design: Thirty five freshly extracted sound human maxillary first premolars were used and randomly divided into the following groups; Group I (Control group): included 5 teeth immersed in distilled water. Group II (Power Horse group): 15 teeth were immersed in 330ml of the drink. Group III (Cornelius group): 15 teeth were immersed in 330ml of the energy drink. After 10 days, the teeth were further randomly divided as follows (5 teeth each); Group IV (Power Horse +Lactose free milk), Group V (Power Horse +Almond milk), Group VI (Cornelius +Lactose free milk) and Group VII (Cornelius +Almond milk). Teeth of groups IV-VII were placed in both types of milk for 5 days where the milk was changed every 2 hrs. The remaining teeth from groups II and III (5 teeth each) were kept in distilled water. At the end of the experimental period, the teeth were prepared for SEM examination, EDX and statistical analyses.Results: SEM examination showed that surface erosion was more aggressive in Power Horse group (II) when compared to Cornelius group (III). Furthermore, the results revealed better remineralizing effect in groups IV and VI (lactose free treated) rather than those treated with almond milk (groups V and VII). EDX results presented statistically significant decrease in Ca and P wt % in group II compared to group III. Statistically significant increase in Ca and P wt % in group IV in relation to group V and similarly, significant increase in group VI compared to group VII were also detected. Conclusion:Energy drinks produce erosive defects of varying intensity on the enamel surface of human teeth. The intake of remineralizing agents; such as milk, immediately following every meal containing acidic diet is mandatory to reverse the demineralization process.

Introduction: Wound healing is a highly complicated event attained through precisely programmed phases. Curcumin was used as a flavoring and coloring agent. It also exhibited remarkable properties in medicinal therapy. Aim: This study aimed to investigate the therapeutic effect of curcumin on healing of induced palatal ulcer in a rat model. Material & Methods: Thirty six male Albino rats were divided into three groups. Group I (Control group): rats were given the vehicle solution. Group II (ulcer induced group): ulcers were created on the hard palatal mucosa of rats of this group. Group III (curcumin & ulcer induced group): ulcers were induced then rats were daily given 200mg/kg of curcumin starting from the day of ulceration. The animals were sacrificed such that two rats from the control group and five rats from the experimental groups were sacrificed after three, six and twelve days post ulceration. Specimens were prepared for histological examination and scanning electron microscopic assessment. Results: Histological examination revealed better enhancement of ulcer healing and epithelization together with establishment of more dense collagen bundles in group III samples when compared to group II throughout the examined experimental periods. Scanning electron microscopic results supported the histological findings showing significant reduction of the ulcer size in group III specimens. Conclusion: oral administration of curcumin has beneficial effects in accelerating wound healing and improving all phases of wound repair of palatal ulcer in rats.
