TOPIC: BASICS OF RADIOLOGY 🌟IMPORTANT POINTS TO REMEMBER 🔹Dental X-ray machine consists of an envelope, tube head, positioning arm, control panel, circuit and supporting stand. It can be of wall-mounted fixed type or mobile. 🔹Tube head consists of glass X-ray tube, tube housing, transformer, lead shield, surrounding oil, tube head seal, filtration, collimator, spacer cone […]
TOPIC: PHYSICS OF RADIATION 🌟 IMPORTANT POINTS TO REMEMBER 🔹John Dalton in 1808 developed his famous ‘Theory of Atom’. 🔹Elemental matter: It is made up of a combination of a single type of atom, e.g. hydrogen atom. 🔹Compound matter: It is composed of recurring units of a specific number of atoms in a definite arrangement […]
GORLIN SYNDROME (Basal Nevus Cell Carcinoma Syndrome) ⭐IMPORTANT POINTS TO PONDER Gorlin syndrome is an autosomal dominant neurocutaneous (phakomatosis) disease characterized by a triad of multiple basal cell nevi, jaw odontogenic keratocysts, and skeletal anomalies. 🔹An odontogenic (primordial) keratocyst is a cyst that arises from a tooth before its calcification. 🔹It is most commonly located […]

TYPICAL RADIOLOGICAL APPEARANCE CONTD. 🔺Brush in winter appearance: Normal sialographic appearance of submandibular gland 🔺Savage like appearance: Sialographic appearance of Sialographic 🔺Snow storm appearance: Sialographic appearance of sjogren’s syndrome 🔺Sialectasis: Sialographic appearance of Sialodenitis 🔺Ball in hand appearance: Sialographic appearance of intrinsic benign tumors 🔺Balloon like appearance: Follicular cyst
TYPICAL RADIOLOGICAL APPEARANCE 🔺Soap bubble appearance: Ameloblastoma, ABC, Central hemangioma 🔺Driven snow appearance: Calcifying epithelial odontogenic cyst 🔺Honeycomb pattern: Calcifying epithelial odontogenic cyst, odontogenic myxoma, hemangioma, giant cell granuloma 🔺Sunburst appearance: Hemangioma, osteosarcoma 🔺Sun ray appearance: Hemangioma, osteosarcoma, osteoblastoma
TYPICAL FEATURES OF LESION 🔸Ameloblastoma: Eggshell cracking 🔸Pyogenic granuloma: Hourglass appearance 🔸Hodgkin’s disease: Bimodal age incidence peak
LAMINA-DURA Lamina-dura is a radiographic feature appears as a thin radiopaque line surrounding the roots of the teeth, which represents the alveolar bone proper. Presence of intact lamina-dura around the apex of the tooth strongly suggestive of vital pulp.
