Tooth wear and its rehabilitation is a much discussed and studied subject in dentistry. The increased life expectancy may be one of the factors that it has become more ubiquitous. Often patients with tooth wear report to the dental clinic requiring extensive restorative treatment. Wear can be the result of attrition, abrasion, erosion or abfraction. The clinical presentation may vary and can be...

A stream of conscious experience is extremely contextual; it is impacted by sensory stimuli, drives and emotions, and the web of associations that link, directly or indirectly, the subject of experience to other elements of the individual's worldview. The contextuality of one's conscious experience both enhances and constrains the contextuality of one's behavior. Since we cannot know first-hand...

Tooth size arch length discrepancy (TSALD) is a well defined means of assessing dental crowding. In previous literature conflicting evidence exists regarding the part played by tooth size and arch dimension in causing dental crowding. The objective of present study were to; examine the relationship between tooth size and arch dimension in crowded and non crowded arches, and to find out the majo...

Orthodontic tooth movement (OTM) is a dynamic process of bone modeling involving osteoclast-driven resorption on the compression side. Consequently, to estimate the influence of various situations on tooth movement, experimental studies need to analyze this cell. Objectives The aim of this study was to test and validate a new method for evaluating osteoclastic activity stimulated by mechanical ...

Gear’s normal contact stiffness played an important role in the mechanical equipment. In this paper, the M-B fractal model is modified and the contact surface coefficient is put forward to set up the fractal model, considering the influence of friction, which could be used to calculate accurately the involute arc cylindrical gears’ normal contact stiffness based on the fractal theory and Hertz ...

Teeth are an integral part of facial aesthetics involved in complex social, cultural & psychological interaction. Of all, latest, tooth color measurement has attracted attention the field dentistry for assessing age. To assess correlation between enamel and chronological age to evaluate individual from color. This was a cross sectional study that included total 200 individuals attending outp...

It is well established that tooth extraction is followed by a reduction of the buccolingual as well as the apicocoronal dimension of the alveolar ridge. Different measures have been taken to avoid this bone modelling process, such as immediate implant placement and bone grafting, but in most cases with disappointing results. One fundamental principle of bone physiology is the adaptation of bone...
