Clinical Studies of Dental Erosion and Erosive Wear [PDF]

open access: yesCaries Research, 2011
We define <i>erosion </i>as apartial demineralisation of enamel or dentine by intrinsic or extrinsic acidsand <i>erosive tooth wear</i> as the accelerated loss of dental hard tissue through the combined effect of erosion and mechanical wear (abrasion and attrition) on the tooth surface.

Rainfall erosivity and erosivity density through rainfall synthetic series for São Paulo State, Brazil: Assessment, regionalization and modeling

open access: yesInternational Soil and Water Conservation Research, 2022
Rainfall is the main cause of erosion of Brazilian soils, which makes assessing the rainfall erosivity factor (RE) and the erosivity density (ED) fundamental for soil and water conservation.

Dental Erosion [PDF]

open access: yesPolish Journal of Public Health, 2014
Dental erosion is described as an irreversible loss of dental hard tissue resulting from exposure to non-bacterial acids or chelating substances. It may be caused by exogenous or endogenous factors. In the former case, food, drink, as well as the environment might be sources of acids; in the latter, acids flowing into the oral cavity from the stomach ...

Evaluating Rain Erosivity Indices Using Geostatistical Techniques in GIS Environment (Case Study: Golestan Province) [PDF]

open access: yesجغرافیا و آمایش شهری منطقه‌ای, 2022
Today, Soil erosion is considered as one of the important issues of watershed management at the national and global levels. Estimating risk of soil reduction and its spatial distribution is one of the key factors for successful assessment of soil erosion.

Spatiotemporal variation and tendency analysis on rainfall erosivity in the Loess Plateau of China

open access: yesHydrology Research, 2020
Rainfall erosivity is an important factor to be considered when predicting soil erosion. Precipitation data for 1971–2010 from 39 stations located in the Loess Plateau of China were collected to calculate the spatiotemporal variability of rainfall ...

Spatial and temporal estimation of the erosivity factor R based on daily rainfall data for the department of Atlántico, Colombia

open access: yesIngeniería e Investigación, 2015
Soil erosion caused by rain is the detachment and movement of soil particles caused by the impact of raindrops on the surface. Erosivity factor R is a measure of the rain erosive power used for estimating the erosion rate with the RUSLE method (Revised ...
