Today, in image analysis the broadest possible rationalization and economization have become desirable. Basically, there are two approaches for image analysis: The image analysis through the so-called scanning methods which are usually performed without the human eye and the systems of optical semiautomatic analysis completely relying on the human eye.The new MOP AM 01 opto-manual system (fig.) represents one of the very promising approaches in this field. The instrument consists of an electronic counting and storing unit, which incorporates a microprocessor and a keyboard for choice of measuring parameters, well designed for easy use.Using the MOP AM 01 there are three possibilities of image analysis:the manual point counting,the opto-manual point counting andthe measurement of absolute areas and/or length (size distribution analysis included).To determine a point density for the calculation of the corresponding volume density the intercepts lying within the structure are scanned with the light pen.

Dental Whitening

Dental unit darkening is the cause of aesthetic complaint by the patient, mainly because it is easily noticed by the human eye. Tooth whitening and ceramic veneers allow aesthetic rehabilitation in a pattern of visual equality to the natural dentition, by restoring teeth color and shape symmetry, bringing to the face a harmonious impact that is reflected in the entire set that composes it. By recovering teeth healthy appearance, this association of procedures restores people’s self-confidence. This study reports a clinical case of an esthetic management for darkened tooth 21, describing the sequence of techniques association of dental whitening and ceramic veneer to achieve aesthetics balance, showing the advantages and limitations of these procedures.

The operating microscope is of paramount importance for the endodontist to develop his work with a higher quality and safety to achieve the success of a treatment to be developed, being able to help him in several clinical cases that may arise during the day-to-day of care, from its magnification (providing a greater amount of details that would normally go unnoticed by the human eye) and from its coaxial lighting (capable of eliminating shadows in the region to be worked), which can be used from the moment of diagnosis until its completion and complications, such as fractures of instruments that need to be removed
