Sjögren's Syndrome and Sialography Sjögren's syndrome is an autoimmune disorder characterized by the destruction of exocrine glands, particularly the salivary and lacrimal glands, leading to dry mouth (xerostomia) and dry eyes (keratoconjunctivitis sicca). One of the diagnostic tools used to evaluate the salivary glands in patients with Sjögren's syndrome is sialography. Sialography Findings in Sjögren's Syndrome Sialectasi…

Bacterial endocarditis  Endocarditis is an infection of the endocardium of the heart, most often affecting the heart valves. A. Acute endocarditis 1. Most commonly caused by Staphylococcus aureus. 2. It occurs most frequently in intravenous drug users, where it usually affects the tricuspid valve.  B. Subacute endocarditis 1. Most commonly caused by less virulent organisms, such as intraoral Streptococcus viridans that can be introduced systemi…

Anatomy of Maxilary Edentulous Ridge LIMITING STRUCTURES A) Labial & buccal frenum - Fibrous band covered by mucous membrane. - A v-shaped notch (labial notch) should be provided very carefully which should be narrow but deep enough to avoid interference - Buccal frenum has the attachment of following muscles; levator anguli  - It needs greater clearance on buccal flange of the denture (shallower and wider) than the labial frenum. B) La…

Stationary Relationship a) .Centric Relation is the most superior relationship of the condyle of the mandible to the articular fossa of the temporal bone as determined by the bones ligaments. and muscles of the temporomandibular joint; in an ideal dentition it is the same as centric occlusion. (b) Canines may also be used to confirm the molar relationships to classify occlusion when molars are missing; a class I canine relationship shows the cusp tip of the ma…
