Case 47: Occlusal stamp technique for direct composite restoration
As the name indicates, a stamp is a preformed contour which impresses or creates a replica when placed on an object. With regards to dentistry, in the field of composite restorations any pit and fissure decay which requires a restoration and has not covitated the tooth structur externally is an ideal candidate for this occlusal stamp technique.

Here in this case its a simple GV Blacks class 1 situation of dental caries on tooth no 2.7. Ther sequence of stemps involved are as follows:
1. After the initial diagnosis and confirmation with a radiograph, The fissures and the occlusal table is cleansed and a very thin coat of vaseline is optional, followed by application of flowable composite on the occlusal table creating a small mound. Before curing it place a small plastic applicator tip and then light cure it. Once done just tease the composite with a sharp tip of an explorer and it will easily pop out. Now the occlusal stamp is ready.




2. Complete the cavity preparation and isolation with rubber dam.




3. Etch and bond the prepared tooth surface.



4. Apply the bulk-fill composite and place a thin teflon on the surface covering the occlusal table. Now use the stamp and seat it just like how it was before taking it out.




5. Now light cure from the external and then remove the stamp and the teflon and complete the curing. Any excess flash can be trimmed and finished.

6. Final finishing and polishing is carried out and occlusion assessed.

This case was done by me at Parasu Dental College, Chennai

Case 45: Cementation protocol for an emax- lithium disilicate crowns The chances for dislodgement of an all ceramic especially a glass ceramic is possible when isolation is not maintained during it cementation. Here is a case with a dislodged emax crown which was done somewhere else a year ago. Bonded restorations normally have an excellent durability and longevity if luted following proper cementation protocols. So what do we do to achieve that protocol? Step 1: Isolate the tooth or teeth using a Heavy rubber dam and use of either Brinker clamps or Tie floss can be done to expose the finish line margin. In this case the margini was supra-gingival and hence a tie-floss technique was employed. Step 2: Treating the cementing surface of the crown. Use of ultrasonics to remove any excess cement flecks attached to the crown is removed. Ideally if u have aluminium oxide air blast it can be used once. Later use 9% or 10% Hydro fluoric acid and etch the glass surface for 90 sec

infective endocarditis & its dental prophylaxis..

Definition Subacute Bacterial Endocarditis (SBE) is a bacterial infection that produces growths on the endocardium (the cells lining the inside of the heart). Subacute bacterial endocarditis usually (but not always) is caused by a viridans streptococci (a type of bacteria); it occurs on damaged valves, and, if untreated, can become fatal within six weeks to a year. Description Endocarditis has traditionally been classified as acute or subacute based upon the pathogenic organism and the clinical presentation. This distinction has become less clear, however, and the less specific term "infective endocarditis" is now more commonly used. Most patients who develop infective endocarditis have underlying cardiac disease, although this is frequently not the case with intravenous drug abusers and hospital-acquired infections. Important factors that determine the clinical presentation are: 1.the nature of the infecting organism 2.whether the infection is superimposed upon preexisting a

Case 50: Full mouth rehabilitation-Digital Dentistry-Digital Smile Design of a patient with Amelogenesis Imperfecta. Amelogenesis imperfecta is a developmental defect where the developement of enamel is affected. The condition may vary from simple white flecks of enamel hypoplasia to severe pitting with brown-yellow discolored teeth. Here is a patient who was a teenager and was emotionally & psychologically affected because of his unesthetic teeth. Reason is, he had amelogenesis imperfecta which was severe involving all his teeth with yellow brown discolorations along with pitting in the posterior teeth. Transforming smile and improving his psychological level can be achieved by first gaining the confidence and trust. This emotional dentistry can be fulfilled by Digital Smile design. As discussed in many of my cases, I use Adobe photoshop for my smile designing part. The very same day the patient walked in, photographs and videos were taken to plan the smile and re-enforce th
