TOPIC: DISORDERS OF PARANASAL SINUS 🌟 IMPORTANT POINTS TO REMEMBER 🔸Sinusitis: Sinusitis is the inflammatory condition that causes generalised inflammation of the PNS mucous membrane. 🔸Pansinusitis: All the sinuses will be involved, and may be unilateral or bilateral. There is fever, general malaise, bodyache and headache, usually confined to forehead, and there is also postnasal […]
TOPIC: TUMORS OF JAW 🌟 IMPORTANT POINTS TO REMEMBER 🔸Ameloblastoma: It is also called adamantinoma. It begins as a central lesion of bone which is slowly destructive but tends to expand the bone rather than perforate it. Teeth in the involved region may be displaced. Radiographically, classic ameloblastoma appears as multilocular cyst-like lesion and gives […]
TOPIC: TEMPOROMANDIBULAR JOINT DISORDERS 🌟 IMPORTANT POINTS TO REMEMBER 🔹The condylar head with its cartilaginous surface is particularly vulnerable to environmental and genetic influence leading to growth disturbance. 🔹In unilateral hypoplasia of condyle sigmoid notch is shallow. Prominent antegonial notch is seen on the affected side.
TOPIC: DEVELOPMENTAL DEFECTS OF CRANIOFACIAL REGION 🌟 IMPORTANT POINTS TO REMEMBER 🔸Facial Hemihypertrophy: It is also known as Friedreich disease. Enlargement of half face occurs. On radiograph there is enlargement of bone to the affected side of the skull. 🔸Facial Hemiatrophy: It is also known as Parry–Romberg syndrome. There is appearance of white furrow on […]
TOPIC: CYSTS OF THE JAW 🌟 IMPORTANT POINTS TO REMEMBER 🔹Dentigerous Cyst: Dentigerous cysts develop around the crown of an impacted or embedded unerupted or supernumerary tooth. Cysts may undergo neoplastic transformation to an ameloblastoma called muralameloblastoma and mucoepidermoid carcinoma. 🔹Dentigerous Cyst appears as a well-defined radiolucency with sclerotic borders. Radiographically, the dentigerous cyst […]
TOPIC: DENTAL CARIES 🌟 IMPORTANT POINTS TO REMEMBER 🔹Interproximal Caries: Interproximal caries begin just below the contact point, and it has a small notched radiolucent appearance on the radiograph. Clinically, there is a white spot lesion which is slightly roughened due to demineralisation. 🔹Incipient Interproximal Caries: The carious lesion often forms a classical V-shaped or […]
TOPIC: RADIOLOGICAL ASPECTS OF INFLAMMATORY LESIONS 🌟 IMPORTANT POINTS TO REMEMBER 🔸Periodontal Ligament Space: Accumulation of inflammatory exudates in the connective tissue of the periodontal ligament causes oedema and this causes widening in the periodontal ligament space. The non-pathological reasons for widening of periodontal ligament space are terminal stage of root formation. 🔸Lamina Dura: Loss […]
TOPIC: PERIODONTAL IMAGING AND DISEASES 🌟 IMPORTANT POINTS TO REMEMBER 🔸Technique Used: The standard exposure technique for periodontal imaging procedures is undoubtedly the intraoral radiography using a strict paralleling technique. 🔸Digital Radiography: In digital radiography dedicated software for periodontal filtering may offer an optimised image to inspect crestal cortication, lamina dura and periodontal ligament space. […]
TOPIC: TEETH ANOMALIES 🌟IMPORTANT POINTS TO REMEMBER 🔸MACRODONTIA AND MICRODONTIA: Teeth are larger than normal in macrodontia. 🔸AMELOGENESIS IMPERFECTA: It has various types – hypoplastic type (enamel of the affected teeth fails to develop to its normal thickness), hypomaturation type (enamel shows a mottled appearance; it is softer than normal and appears cloudy white, yellow […]
CONTRAST AGENTS 🌟IMPORTANT POINTS TO REMEMBER 🔹Definition: Contrast agents is defined as radiopaque substances that have been developed to alter artificially the density of different parts of the patient, thus altering the subject contrast. 🔹Requirement of Contrast Media: The contrast media should be adequately radiopaque to show good contrast. They should be viscous enough that […]
