Unusual Root Staining of the Third Molars in a Patient Exposed to Lead and Tetracyclinec

Intrinsic staining of teeth can result from introducing a variety of substances into the body which can form complexes with hard tissues (enamel, dentine, and bone). Two well-known substances that can cause such intrinsic staining of the teeth are lead and tetracyclineclass medications. Lead has been used for centuries in many industrial processes such as the development of batteries, sheets for X-Ray films, protective gear for high-radiation purposes (lead doors and lead gowns), and more stigmatically in the past, gasoline and paint. Lead poisoningoccurs when a person of any age swallows, absorbs, or inhales lead in any form. 

Tetracycline


Tetracycline and some of its homologues, such as minocycline, have a tendency to deposit in the hard substance of tooth and bone by forming a tetracycline-calcium-orthophosphate complex, which produces an intrinsic stain. The intensity of the stain depends on the dosage, duration of treatment, and age of onset of treatment. The age of onset of the treatment using tetracycline based medications is also important in determining the pattern of staining, such as the stratification of staining of the root(s).

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

Indications for Orthognathic Surgery

Image
Orthognathic surgery (OS) is a surgical intervention that alters relationships of the jaws and dental arches. The treatment involves a combination of orthodontics and maxillofacial surgery.  Orthognathic Surgery It is used to correct dentofacial deformities that cannot be treated with acceptable results by conventional orthodontics. The first description of a surgical intervention to correct a malocclusion was by Hullihen in 1849. The most frequently used surgical procedures for correcting the relationship of the jaws are Le Fort I osteotomy and sagittal ramus split osteotomy. Also often used are vertical ramus osteotomy, inverted L osteotomy, and variations and combinations of the above. Read More>>>>>>
