Effect of Centric Interference on Canine Tooth Wear
… term effect of a centric interference on canine tooth wear (CTW) and on centric occlusion (CO) and maximal intercuspation (MIP) variance. Materials and Methods: Thirty subjects, 11 males and 19 females, were selected based on inclusion and exclusion criteria. Changes in enamel volume were studied …

Tooth wear in Irish teenagers: a laboratory and epidemiological study
… characteristics, development and determinants of toothwear among Irish schoolchildren. Methods: A cross-sectional (examination at 16-years-old) and longitudinal (examinations at 5-,12-,14-years) study were conducted. Two indices were used to measure toothwear, children/parents completed a …

Age effect on presence, susceptibility and treatment of erosive tooth wear
Erosive tooth wear (ETW) is a growing dental condition often associated with aging. This in-vitro project comprised three studies aiming to investigate the impact of tooth age on ETW susceptibility and prevention. In the first study, un-identified extracted premolars were collected and had their …

The prevalence of caries and tooth wear in cleft children aged between 6 months and 6 years in the West of Scotland.
Aim: To compare the prevalence of caries and tooth wear in the primary teeth of children with clefts with comparable national data and to determine whether there is an association between the occurrence of a cleft and socioeconomic deprivation in the West of Scotland. Method: Ethical approval was …

An in vitro investigation into the effects of sports gels/drinks on human hard tissue – Consumer habits and Dentist knowledge
<b>Introduction</b><b><br/></b>Tooth wear has become increasingly prevalent among all age ranges of the human population and with an increase in the numbers maintaining their dentition to later years, it can be a challenging dilemma to manage in many aspects. The increase in prevalence occurring in …

Molar Wear Patterns in Macaca Fascicularis, Presbytis Cristatus and Presbytis Rubicunda: A Photogrammetric Analysis
… and given that molar form changes with wear, animals with different diets might be expected to show differences in tooth wear related to their differences in diet.

The fate of neonate calves. A discussion of the bovine infant health implications of dairying in antiquity, using archaeozoological studies of six Orcadian contexts.
… early developmental stages in molariform teeth; tooth-wear methodologies are imprecise at this stage before wear commences. Known-age modern bovine foetal and neonate material are collected as a control assemblage for method development (n=73); six Neolithic to Norse era assemblages from Orkney …

Estrutura da variação craniana em populações de Bolomys lasiurus (Lund, 1841) (Rodentia: Cricetidae) do Nordeste do Brasil
… a first step, the correlation structures between tooth wear and suture ossification indexes are evaluated to access possible effects of sex, vegetation, season and local variation among samples of 31 sites on craniodental estimators of rela tive age and to improve age determination for …

Three dimensional surface texture analysis for characterisation of enamel erosion
… the effect of acid-mediated erosive enamel wear on the micro-texture of polished (Group 1) and unpolished (Group 2) human enamel in vitro. 20 polished and 20 unpolished enamel samples were prepared and subjected to a citric acid erosion and pooled human saliva remineralisation model. For the …

The ecology and utilisation of Lumholtz's tree kangaroos Dendrolagus lumholtzi (Marsupialia: Macropodidae), on the Atherton Tablelands, far north Queensland.
… tree-kangaroos can be simply aged using a tooth wear index developed during this study. Aging is essential for establishing demographics, such as age specific mortality and fecundity of populations, currently unknown in D. Iumholtzi. Without the ability to age populations we cannot reliably …
