Abstract This in vitro study used the same frequency and duration of acid contact as a previous situ/in vivo to evaluate effect erosion on CAD/CAM restorative materials human enamel compare effects challenges enamel. The (IPS e.max CAD, Lava Ultimate, PMMA block) were eroded by immersion 150 ml cola drink for 14 days (4 × 5 min/day). surface microhardness roughness specimens measured at baselin...

The capability of a soft drink or a juice to erode dental enamel depends not only on the pH of the drink, but also on its buffering effect. As the latter is the ability of the drink to resist a change of pH it may add to the effects of the actual pH. The aim of the present study was to compare the pH and the buffering effect of various soft drinks with their erosive effects and the solubility o...

BACKGROUND Large food portion sizes are determinants of a high caloric intake, especially if they have been made attractive through value size pricing (i.e. lower unit prices for large than for small portion sizes). The purpose of the two questionnaire studies that are reported in this article was to assess the impact of proportional pricing (i.e. removing beneficial prices for large sizes) on ...

An investigation by The BMJ has uncovered evidence of the extraordinary extent to which key public health experts are involved with the sugar industry and related companies responsible for many of the products blamed for the obesity crisis through research grants, consultancy fees, and other forms of funding. Among the main targets in the United Kingdom for an industry facing increasing pressur...

This study evaluated by an in vitro model the effect of beverages on dental enamel previously subjected to erosive challenge with hydrochloric acid. The factor under study was the type of beverage, in five levels: Sprite® Zero Low-calorie Soda Lime (positive control), Parmalat® ultra high temperature (UHT) milk, Ades® Original soymilk, Leão® Ice Tea Zero ready-to-drink low-calorie peach-flavore...
