Case 4: Severely discolored stump- Zirconia As the savior

 Not always emax is going to be suitable. Certain situations like the one we are going to have a look, where the underlying dentin is terribly discolored needs a masking effect in the crown.
This patient came with dis-satisfied anterior metal ceramic crown along with a discolored non vital maxillary central incisor.


Initially, I had thoughts of doing an internal bleach in 1.1 and remove the crown in 2.1 and assess. But after removal of crown in 2.1 I had doubts in bleaching the underlying discolored stump. It was blackish and i decided to choose Zirconia with an opaque core as more recent zirconias have improved tranlucency.
This eventually made me go ahead with two crowns rather than doing just a single crown. I prefer cementing Zirconia crowns with GIC cement and that has been a personal choice, although there is a huge debate in choosing a resin cement with necessary surface treatment on the intaglio surface of zirconia.



This case was done by me at Parasu Dental Hospital, Chennai.

Case 45: Cementation protocol for an emax- lithium disilicate crown

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
