THE NEW BEST RESIN COMPOSITE FOR ROOT CANAL TREATMENT IS FOUND.




Following an endodontic treatment, if the remaining tooth structure is not adequate for the stable retention of a direct core build-up material, insertion of post into the canal is a treatment option to retain the core. The post can be metal, fiber, or ceramic. Metallic posts have poor stress distribution due to differences in the elastic modulus of metal and dentin, which can occasionally cause root fracture and the potential discoloration of surrounding soft tissue. The use of glass fiber posts has advantages, such as more rapid treatment and better biocompatibility, aesthetics, corrosion resistance, and similar biomechanical properties to dentin. 

ROOT CANAL TREATMENT

When loaded, adhesively luted endodonticreinforced with glass or quartzlead to better homogeneous tension distribution than rigid metal or zirconium oxide ceramic. Moreover, it has been reported that, compared with traditional metallic cast posts, glass fiber posts decrease the likelihood of irreparable root fracturesTo prevent cohesive failure of the material that enhances the retention of root dentin, the use of resin composites should be evaluated. Low elastic modulus (with respect to fiber posts) and direct bonding to the root dentin are advantages of resin composites. PDF LINK.......

Harvesting Free Palatal Masticatory Mucosal Graft Using 3a Mucotome

Image
The technique of free autogenous gingival grafting (FGG) has undergone little modification since its introduction by Bjorn in Scandinavia in 1963 and by King and Pennel inthe United States in 1964. The technique is widely used to treat a variety of mucogingival problems such as insufficient or lack of attached gingiva, the presence of high frenum attachments, shallow fornix and denuded roots following gingival recession.  FGG can be procured from donor site using scalpels, gingivectomy knife or palatal shaving knife (Paquette knife). The donor site is frequently the palate, although the use of edentulous ridge areas, tuberosity and attached gingiva has also been described. Scalpel is most commonly used and conventional method for procuring gingival auto grafts. Gingivectomy knife, although not commonly used, also works on similar principle. Since the scalpel blade is straight and stiff and the palate is curved, repeated incisions to release the graft from underlying connecti

Dental Ailments may be risky for Cardiac Patients

Image
Patients that are suffering from cardiac t=disorders are susceptible to physical and mental stress. Dental ailments add to the stress further as these patients are unable to cope with the pain due to cardiac disorders. These patients may encounter medical emergencies in case of dental disorders and they may demand multi disciplinary approach to achieve the success. Additionally, the results of cardiac surgery may suffer if the oral cavity is not maintained well since there is always a fear of infection affecting the heart from the oral cavity. Hence, the cardiac surgeon has to refer surgical patients to a dentist for oral prophylaxis and to treat any oral infections before cardiac surgery to prevent infective endocarditis. PDF LINK

Non-Instrumented Silver Point Retreatment Using the GentleWave Procedure

Image
Apicoectomies are required for endodontically treated teeth instead of the preferred non-surgical endodontic therapy when biological or technical factors necessitate this therapy. These biological or technical factors may include, but are not limited to, non-healing periapical lesions, persistent clinical symptoms, separated instruments or silver points and the presence of long posts. Success rates for apicoectomies have been reported up to 78% with as many as 4% of endodontically treated teeth requiring this type of surgery. Although success rates are relatively high, once the tooth is no longer a candidate for non-surgical endodontic treatment, the alternatives in lieu of apicoectomy are limited to extraction with no replacement or replacement with a fixed prosthesis, removable prosthesis or implant.
