Dental Biometrics:
this seminar describes foundations of a biometric system for semi-automatic processing and matching of dental images, with the final goal of human identification. Given a dental record, usually as a postmortem (PM) radiograph, And need to search the database of antemortem (AM) radiographs to determine the identity of the person associated with the PM image.use a semi-automatic method to extract shapes of the teeth from the AM and PM radiographs, and find the affine transform that best fits the shapes in the PM image to thos ....etc

INTRODUCTION OF PROJECT



The basic objective of this project regarding “COMPUTERIZATION OF A DENTAL CLINIC” is to eliminate the use of conventional methods of storing records (Viz. on papers, files) which are obviously time consuming, cumbersome and also require more storage.
Thus, computerization should allow quick storage of records and quicker completion of other formalities as well.
It would also lead to easier access the records and ....etc

Posing a great challenge to the traditional Charge Coupled Devices (CCD) in various applications, CMOS image sensors have improvised themselves with time, finding solutions for the problems related with the noise and sensitivity. The use of Active Pixel Sensors having its foundation with the sub-micron technologies have helped to attain low power, low voltage and monolithic integration allowing. The manufacture of miniaturised single-chip digital cameras is an example of this technology.

The incorporation of advanced techniques at the chip ....etc

Abstract:
Dental Composites to Degraded MLI:


Ben Reed's experience as a materials engineer has led him from the challenges of dental composites to long term space exposure on the Hubble Space Telescope (HST).

Dental composites were developed in the 1960s and have continued to play a major role in restorative dentistry to date. However, they do not exhibit the typical service life of silver amalgam or gold fillings. Much of their lower service life is due to the consequences of polymerization shrinkage.

The Hu ....etc

charge-coupled device (CCD)

A charge-coupled device (CCD) is a light-sensitive integrated circuit that stores and displays the data for an image in such a way that each pixel (picture element) in the image is converted into an electical charge the intensity of which is related to a color in the color spectrum. For a system supporting 65,535 colors, there will be a separate value for each color that can be stored and recovered. CCDs are now commonly included in digital still and video cameras. They ....etc

INTRODUCTION

Teeth (singular tooth) are small, calcified, whitish structures found in the jaws (or mouths) of many vertebrates that are used to tear, scrape, and chew food. Some animals, particularly carnivores, also use teeth for hunting or defense. The roots of teeth are covered by gums. Teeth are not made of bone, but rather of tissues of varying density and hardness ....etc
