We describe a higher magnifying power operating microscope system to improve one method of high-quality microsurgical clipping for cerebral aneurysm in some cases. This higher magnification is achieved by a new lens design in the optical system, which makes the image of the object very clear at high magnifications (distinctiveness of 7 μm). This higher-resolution operating microscope system pro...
Materials and methods: Mixed populations of 50 human first and second incisors were mounted in acrylic dento-form blocks. Conventional access cavities were completed without operation microscope, while attempting to locate and subsequently negotiate the second canals. The teeth in which second canal was not located or could not be negotiated were then submitted under Operating Microscope. The r...
The aim of this work was to study the structure of dental pulp (mainly the connective tissue fibre and odontoblasts) during the active production of dentine in relation to the age of the patient. The pulps of the teeth extracted for orthodontic reasons from a population of 10-50 year-olds were investigated with the help of a transmission electron microscope (TEM) and a scanning electron microsc...
Dental wear can be differentiated into different types on the basis of morphological and etiological factors. The present research was carried out on twelve extracted human teeth with dental wear (three teeth showing each type of wear: erosion, attrition, abrasion, and abfraction) studied by scanning electron microscopy (SEM). The study aimed, through analysis of the macro- and micromorphologic...
