TotalFill a newly developed pulp-capping material, offers results comparable to BD in addition to its advantageous handling properties. Although TheraCal LC contains resin ingredients, given proper curing, it seems to be a successful material for DPC and offers superior handling properties.

Objective The objective of this study was to investigate enamel remineralization using lyophilized extract from Moringa Oleifera Leaves (MOL). Materials and methods A total of seventy-five teeth were selected and randomly divided into 5 equal groups (n = 15). All teeth were air dried for 30 s, two windows (right and left) were drawn on the labial surface of each tooth. The right window was set as the control and no etching or treatment was performed. The left window was etched for 30 s for all five groups. After etching, group I received no treatment, group II received plain varnish, group III received fluoride varnish, and finally groups IV and V received plain varnish loaded with 50 mg/ml and 200 mg/ml of lyophilized MOL extract respectively. All samples were then immersed in artificial saliva for 14 days. The specimens were examined under scanning electron microscope (SEM) and energy dispersive x-ray (EDX). Results SEM micrographs revealed that MOL extract loaded-varnish groups IV & V showed the most re-establishment of normal enamel architecture. Elemental analysis of the treated surfaces of Groups IV and V showed the surfaces treated by MOL loaded-varnish groups had significantly higher Ca, P, and O deposition than the fluoride varnish group. Conclusion MOL might be considered as a biomimetic material capable of guiding enamel tissue remineralization.

One of a synthetic food dye which used worldwide is Tartrazine, it is an orange-colored, water soluble with a potential toxicological risk. Food or drinks containing tartrazine caused sensitivity symptoms. Vitamin E is an essential lipid-soluble vitamin and has well-established antioxidant properties which improve the proliferation, differentiation, and mineralization, and reduced apoptosis of osteoblastic cells.Aim of this study: to evaluate the effect of tartrazine and co-administration of vitamin E on post extraction socket using histological examination by light microscope. Materials and methods:Surgical extraction of mandibular first molars were done in a twenty one albino rats, the animals were randomly divided into 3 groups; group I (control), group II given tartrazine and group III given tartrazine and Vitamin E (treated group).
