Transient Paresthesia after Surgical Removal of Embedded Supernumerary Tooth

Paresthesia is a sensory pathology which clinically manifests as numbness, pricking, tingling and burning. However it can informally referred to any abnormal sensation. Due to its anatomical location which is more superior position in the jaw compared with the other parts of the inferior dental canal, the mental foramen region is a common area for nerve damage to occur. Therefore, extra caution should be taken in proper evaluation of the anatomical position of mental foreman that can be situated in critical mandibular regions.
Transient Paresthesia
There are multiple factors that can cause nerve injury including mechanical, chemical and thermal components. Mandibular paresthesia or dysaesthesia for the inferior alveolar nerve/ mental nerve distribution can be associated with local or systemic factors. The local factors are divided to endodontic and surgical etiology. The endodontic etiologic factors are the severe endodontic infection involving the nerve and the iatrogenic sequelae of endodontic therapy.  Read more......

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.
