Comparision between Conventional Radiography (IOPA) and Digital Radiography

Diagnosis is the process of assessing a patient’s health as well as ensuing opinions formulated by clinicians. Oral diagnosis is the art of using scientific knowledge to determine the nature of oral diseases and distinguishing it from other diseases .Radiography is a well established procedure in daily dental practice and is still the most basic and an important diagnostic tool available. Radiographs play an integral role in the assessment of periodontal diseases. Conventional bitewing and intra oralperiapical radiographs are commonly used to detect alveolar bone loss associated with periodontal disease. They provide unique information about the status of the periodontium and a permanent record of the bone throughout the course of the disease. However, the quality of an X-ray sensitive film can be affected by multiple variables such as improper exposure, underor overdeveloping and poor fixing.

Alveolar Bone Loss Over the past few years, systems that can generate radiographic digital images without the need for radiography film have become available for use in clinical practice and are gaining popularity among practitioners. Such digital radiography can also reduce the radiation exposure. One of the most useful advantages of digital radiography is the knack it provides to the clinicians to send images to practitioners in a matter of minutes, for which it has become widely accepted as an alternative to film-based radiography .A few studies (most of which were performed in vitro) that examined the use of digital radiography in evaluating crestal alveolar bone loss associated with periodontal disease listed out few of its main advantages over conventional radiography to be speed, convenience, lack of dark room procedures, image improvement tools and dose reduction. Thus the implementation of digital radiography in a dental practice seems to provide a solution for the future imaging requirements.

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 conn...

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>>>>>>

Oral Health Problems among Diabetic Patients ? Part of Dental Professionals in Diagnostic and Therapy

Image
Sickness-changes within the oral cavity are to be considering both as the complication of the diabetes as well as the reason of the difficulty in the metabolic compensation of the illness. Every chronic hyperglycaemia, aside from its reasons, leads to the activation of the process of not enzymatic glycation of proteins, poliolic route and the oxidative stress. The chronic hyperglycaemia and related inflammation leads to the disturbances in the balance between the metaloproteinase system and their inhibitors (MMP/TIMP), what becomes a reason of the pathological reconstruction of the vascular wall,the proliferation of the endothelium and arteriogensis . Inflammatory focus in the human body, including the oral cavity, can on one hand be the reason of disturbances of the metabolic control of the diabetes, from the second hand – can accelerate the development hyperglycaemia related vascular complications.  Many authors think that fundamental role in the occurrence of complicat...
