The last 50 years have witnessed an unbelievable amount of change
in restorative dentistry. The evolution of materials and techniques
has been so enormous that it has become virtually impractical for
the clinician to keep abreast. An area of major change has been the
ceramic restoration. The first break through came about with the
introduction of the porcelain-fused-to-metal restoration. The
ability to fire and fuse porcelain against gold alloy or base
metals considerably extended the use of ceramic materials. Suddenly
it was possible not only to generate single units of porcelain for
anterior and posterior teeth but also to fabricate extended partial
dentures. It is important to note that ceramic veneering of metal
crowns or copings resulted in changes not only to the ceramic
material but also to the casting alloys themselves. By using metal
substrates with a higher casting temperature and a ceramic material
with a lower fusion range, highly esthetic and durable restorations
could be developed. This method of restoring missing teeth
continues to play a very important role in the field of
prosthodontics.
Remineralization is increasingly accepted as a viable non-invasive
approach for restoring carious teeth, at least during the earlier
stages of the caries process. According to the principles of
minimal intervention dentistry, optimal non-invasive strategies are
preferred for treatment of early enamel lesions. This study was
designed to investigate the remineralising efficacy of casein
phosphopeptide amorphous calcium phosphate on early enamel lesions
using energy dispersive x-ray analysis for quantitative assessment
and scanning electron microscope for morphological changes. It can
be inferred from the study that casein phosphopeptide amorphous
calcium phosphate paste significantly remineralises the early
enamel lesions substantially .This could be attributed to the
diffusion of calcium and phosphate minerals into the surface with
the aid of saliva as the transport medium. This book gives an
overview of how we can measure the amount of mineral loss or gain
quantitatively along with the morphological changes.
In the past caries diagnosis and treatment was limited to detection
and restoration of cavitated lesions. This drill and fill method
failed to detect the underlying etiologic factor. Preventive
programs should be instituted by analyzing the caries risk of the
patient and providing a customized program to suit the need of
patient. Regular monitoring and appropriate intervention are
critical for changing the oral environment from one of hostility to
one directed towards repair and stability. This book gives an
overview on need for prevention, various modes of caries prevention
and recent advances in caries prevention including the role of
herbs in caries prevention.
