The pathogenesis of the lesion remains unclear, but is often associated with undifferentiated cells in the periodontal ligament, that when stimulated by irritants, for example, calculus, biofilm, the presence of orthodontic appliance with poor hygiene, crowns destruction caused by Carie cavities, traumatic restorations, as well as masticatory forces and impaction of food;
There was one particular case during these past six years working at Plainview Oral and Maxillofacial surgery that made me realize my desire to go to dental school. Dr. Barry Bass and I began preparing for a surgical extraction of the left mandibular second molar. The tooth was infected and formed a large cystic fibroma that was eating away at the patients jawbone. Dr. Bass said this was going to be a long and difficult surgery; nevertheless, I was prepared for the challenge. I reviewed the Cone Beam CT scan to see what specific instruments the doctor may want for the surgery, other than the general surgical tray.
Occlusion: Occlusion can be defined very simply:”it means the contact between teeth”. the concept can be further refined by defining those contacts between the teeth when the mandible is closed and stationary as the static occlusion, and those contacts between teeth when the mandible is moving relative to the maxilla as the dynamic occlusion.  • there are few terms in occlusion which needs to be explained in ordr to understand occlusion in detail. • Static Occlusion: static occlusion is the contact of upper and lower dentition when mandible is not moving. • Centric occlusion (CO): can be described as the occlusion the patient makes when they fit their teeth together in maximum intercuspation.
On the other hand, slight disease affects approximately 35% of the adult population48, 49, 50. Patients need to see the condition of their own mouth. At the initiation of every appointment, during data collection and tissue assessment, the patient should be provided a mirror to visualize with the clinician the evidence of periodontal disease, caries, gingival recession, tooth mobility, furcation involvement, etc. During periodontal probing, the patient should hear the pocket measurements as data is being recorded and collected. In a similar approach, during examination of the radiographs, the patient should be shown evidence of permanent bone loss, and contrast that to areas without bone loss.
Adenoid Cystic Carcinoma term has been coined by Spies in 1930. Adenoid Cystic Carcinoma is a rare malignant tumors which reported to be <1% of all head and neck cancer. Adenoid cystic Carcinoma can arise from different site of the body which contain salivary gland. However, the most commonly site arise from minor salivary gland in oral cavity represent 60%. In other hand, the most major salivary gland site arise from parotid gland.
Chronic periodontitis Chronic Periodontitis is an inflammatory disease of the supporting tissues of the teeth caused by specific microorganisms or groups of specific microorganisms, leading to progressive destruction of the attachment apparatus of the teeth including periodontal ligament, cementum and alveolar bone with periodontal pocket formation, and recession of the gingival tissue(1) . The clinical feature that characterizes periodontitis from gingivitis is the presence of clinically apparent attachment loss. This loss mainly is associated with changes in the density and height of subjacent alveolar bone (1). Severe generalized periodontitis affects 5–15% of any population worldwide and is a major cause of teeth loss after dental caries (2). Chronic Periodontitis also known as adult periodontitis or chronic adult
Abscesses occur for a variety of reasons, cause extreme pain, and can be treated with much success. If left untreated, however, bacteria can spread into other areas of the mouth, causing serious medical conditions. Periodontal disease can cause the formation of an abscess, which is more common in cats that have a tendency to bite or chew frequently. If left untreated, facial or mouth traumas, bacterial infections, and diabetes can all contribute to the formation of an abscess. Symptoms of tooth root abscess are the following: - Bad breath - Loose teeth - Facial swelling - A
Introduction This paper discusses the two types of rhinitis which are allergic and non-allergic and how rhinitis affects the dentition, jaw growth, dental occlusion, and behavior. Rhinitis in adults is discussed as well as the effect of rhinitis on children. Allergic Rhinitis Allergic rhinitis affects more than 1.4 billion people worldwide and is the condition where the immune system recognizes an intruder which in this case is called an allergen. The immune system releases histamine and chemical mediators in response to the allergen, and the nose, eyes, ears, throat, skin and roof of the mouth may experience symptoms.
