INTRODUCTION: CAD/CAM dentistry is a field of dentistry and prosthodontics using CAD/CAM to improve the design and creation of dental restorations. The CAD in this technology stands for “Computer Assisted Design” and the CAM for “Computer Assisted Manufacture”. This technology first adopted to automotive industry and used to design automobile bodies, but now it is spread to the other areas of the industry and one of the major areas is dentistry. CAD/ CAM technology was introduced in dentistry in the early 1980s. Since then it is useful for dentists and for laboratories in produced milled ceramic crows, onlays, inlays, veneers, and bridges. This technology finds application in fabricating dental implant abutments, which are meant to replace missing tooth/teeth. Uses of CAD/CAM in Dentistry • It permits the dental restoration fabrication that includes inlays, onlays, crowns, and bridges.   • It has also been used to make prosthetic, orthodontic appliances

WHAT IS SPLINTING? SPLINTING IN DENTISTRY IS “the joining of 2 or more teeth into a rigid unit by means of fixed or removable restorations or devices.” Dental splint: An appliance designed to immobilize and stabilize mobile loose teeth. (AAP1986 Glossary) RATIONALE FOR SPLINTING 1. To provide rest. 2. Redirects the force in a more axial direction.   3. Redistribution of force so that forces do not exceed the adaptive capacity of the periodontium. 4. To preserve the arch integrity 5. Restores a functional occlusion, stabilizes mobile abutment teeth and increases masticatory efficiency. 6. Gives the patient freedom from mobile teeth 7. To stabilize mobile teeth during surgical, especially regenerative therapy. IDEAL REQUIREMENTS OF A SPLINT   1. Simple.   2. Economic   3. Stable and efficient 4. Esthetically acceptable   5. It should incorporate as many firm teeth as is necessary to reduce the extra load on individual teeth to a

INTRODUCTION The goal of an any procedure performed in a primary tooth are to maintain arch length, preserve masticatory function, remove acute and chronic infection from tooth or oral cavity. Primary molar roots are usually curved to allow for the development of the succedaneous tooth. During instrumentation, these curves increase the chance of perforation of the apical portion of the root or the coronal one-third of the canal into the furcation. Due to the complex morphology of the root canal system in primary teeth, the clinician must rely primarily on chemical cleansing and sterilization and secondarily on mechanical instrumentation during pulpectomy procedure. And in order to increase the chance of success of the endodontic treatment, substances with antimicrobial properties are frequently used as root canal filling materials in deciduous teeth. The main objective of endodontic treatment is total elimination of microorganisms from the root canal, and the preventi

The role which the host's immunoinflammatory responses play in the destruction of the periodontal attachment structures. Several mediators of inflammation have been identified as principal factors in disease progression. •          These include short peptides such as bradykinin, long peptides such as interleukin-1 (IL-1) and complement, amines such as histamine and 5-hydroxytryptamine, and products from cells such as prostaglandins, leukotrienes..                      PAIN   An unpleasant emotional experience usually initiated by noxious stimulus and transmitted over a specialized neural network to the CNS where it is interpreted as such.  (C Richard   Monheim’s) •               An unpleasant sensory and emotional experience associated with actual or potential tissue damage or described in terms of such damage.        Types of p
