Background A sizable increase in the outbreak of tooth attrition and especially dental erosion has been observed. Detection of tooth wear, proper prevention, and effective intervention in the early stage will avoid the adverse effect on teeth performance and elegance. Thus, the current study aimed to determine the level of awareness of senior dental students (general dentists) about the preval...

Whenever the tooth dentin-pulp complex is affected by caries, attrition, erosion, chemicals and abrasion, pulpal response to these injuries can stimulate inflammatory activity. Although the pulp injury caused by these irritants can be important, in many cases the most severe tissue trauma is not a direct result of these environmental or accidental events, instead, it results from the surgical t...

Non-carious cervical lesion (NCCL) is the loss of hard dental tissue commonly observed at the buccal and labial tooth surfaces at the cementoenamel junction (CEJ). Most NCCLs of teeth can be classified into four categories: attrition, erosion, abrasion, and stress-induced cervical lesion. Stress-induced cervical lesions are loss of tooth structure that results from repeated tooth flexure caused...

INTRODUCTION Chronic regurgitation of gastric acids in patients with gastroesophageal reflux disease may cause dental erosion, which can lead in combination with attrition or bruxism to extensive loss of coronal tooth tissue. CASE PRESENTATION This clinical report describes treatment of severe tooth wear of a gastroesophageal reflux disease patient who is 54-year-old Turkish male patient. Aft...

We consider all-pay auctions in the presence of interdependent, affiliated valuations and private budget constraints. For the sealed-bid, all-pay auction we characterize a symmetric equilibrium in continuous strategies for the case of N bidders. Budget constraints encourage more aggressive bidding among participants with large endowments and intermediate valuations. We extend our results to the...

We examine the extent to which readily available data at a large public university can be used to a priori identify at-risk students who may benefit from targeted retention efforts. Although it is possible to identify such students, there remains an inevitable tradeoff in any resource allocation between not treating the students who are likely to exit without treatment and treating students who...

Results: The participants reported an average retention rate of 81.0% 6 17.9%. We found a significant prediction equation (F4,1671⁄4 16.39, R21⁄4 0.282, P , .001), using the perceptions of student success factor (P , .001, R21⁄4 0.162), the timing of formal admission (P , .001, R 1⁄4 0.124), the number of years the ATPs had been accredited (P 1⁄4 .001, R 1⁄4 0.039), the number of students admit...

This paper describes the impact of staff turnover and attrition in a tobacco control program in Scotland. Data collection involved 56 in-depth interviews with program managers and intervention team members. Staff turnover has been recognized as a significant barrier in implementing public health programs, but has never been examined as carefully as in this paper to my knowledge. Understanding h...

The article highlights the contributions of a few prominent women scientists to the science of pharmacology. These women,some of whom were from other scientific fields, contributed significantly to our understanding of pharmacology. This was achieved in an era in which pharmacology was a more or less male dominated field. Even though it is easier for women to enter scientific fields nowadays, t...
