OBJECTIVES The study is to evaluate changes in microhardness of enamel after exposure to acidic center filled chewing gum on primary and permanent teeth. METHODS Thirty primary and 30 permanent molar extracted teeth were painted with acid resistant varnish except a small window over buccal surface. Teeth were divided into four groups according to type of teeth and type of chewing gum (Center ...

Abstract Domains and metric spaces are two central tools for the study of denotational semantics in computer science, but are otherwise very different in many fundamental aspects. A construction that tries to establish links between both paradigms is the space of formal balls, a continuous poset which can be defined for every metric space and that reflects many of its properties. On the other h...

Molasses meal is a popular stock feed which is manufactured from two by-products of the sugar milling process, namely cane flour and molasses. Cane flour, or pulp, is prepared from bagasse by separating the pithy fraction and then drying and milling it. In this form it is capable of absorbing up to four times its own weight of molasses. One such stock feed, produced in Natal, is made up of 75% ...

This paper deals with the conjugation of durian seed gum (DSG) with whey protein isolate (WPI) through Maillard reactions. Subsequently, the functional properties of durian seed gum in the non-conjugated (control sample) and conjugated forms were compared with several commercial gums (i.e., Arabic gum, sodium alginate, kappa carrageenan, guar gum, and pectin). The current study revealed that th...

PURPOSE The aim of this study was to evaluate the lactic acid concentration in supragingival plaque from caries-active pre-school children after a short-term use of either xylitol- or sorbitol-containing chewing gums. MATERIAL AND METHODS The investigation consisted of a prospective crossover design with 10 healthy children aged 2-4 years each with at least two caries lesions within the denti...
