TOPIC: PATIENT MANAGEMENT IN DENTAL RADIOLOGY 🌟 IMPORTANT POINTS TO REMEMBER 🔺Dental radiographers must understand the importance of dental radiographs and their use in the management of the patients. 🔺He or she can be a dental assistant, dental hygienist or dental auxiliary. 🔺Proper dental radiograph is helpful to the dentist for detecting the pathology […]
TOPIC: BITEWING RADIOGRAPHY 🌟IMPORTANT POINTS TO REMEMBER 🔹Position of bite: The tab or bite platform should be positioned in the middle of the film packet and parallel to the upper and lower edges of the film packet. 🔹Position of film packet: The film packet should be positioned with its long axis horizontally for horizontal bitewing […]
PARALLEL LINE ANGLE TECHNIQUE 🌟 IMPORTANT POINTS TO REMEMBER 🔹Parallel line angle technique is also called Fitzgerald technique, long cone technique and extended cone technique. 🔹The central ray of the X-ray beam should be perpendicular to the film and the long axis of the tooth. The film should be placed in the mouth parallel to […]
TOPIC: BISECTING LINE ANGLE TECHNIQUE 🌟 IMPORTANT POINTS TO REMEMBER 🔹Bisecting line angle technique is also called short cone technique. 🔹Cieszynski rule: This rule states that two triangles are equal when they share one common side and have two equal angles. The central ray of the X-ray beam and the imaginary bisector result in formation […]
INTRAORAL RADIOGRAPHY: GENERAL CONSIDERATIONS 🌟 IMPORTANT POINTS TO REMEMBER 🔹Types of intraoral radiography: Periapical Radiography, Bitewing Radiography, Occlusal Radiography 🔹Head position: The chair should be raised high enough so that the occlusal surfaces of the maxillary arch can be visible while taking maxillary views. 🔹Occlusal plane: This should be parallel to the floor.
TOPIC: RADIATION HAZARDS 🌟IMPORTANT POINTS TO REMEMBER 🔹Biological effects: Can be somatic (stochastic effect, deterministic effect) or genetic. The effect can be also acute or immediate effect and chronic or long-term effect. 🔹Immediate effects of radiation are dermatitis, brittleness of the fingernail, epilation and leukopenia. 🔹Chronic or long-term effect: Repeated low levels of radiation exposure […]
TOPIC: RADIATION PROTECTION 🌟 IMPORTANT POINTS TO REMEMBER 🔹Natural radiation: It yields an average annual dose of about 0.79 mSv. It has three components: cosmic radiation, terrestrial radiation and internal sources. 🔹Cosmic radiation: It includes both energetic subatomic particles and photons of extraterrestrial origin that reach the earth.
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 […]
🌟 PERIODONTICS-PSYCHIATRY RELATIONSHIP 📌 POINTS TO PONDER 🔹Psychosomatic disorder in the oral cavity may be caused by either the development of habits that injure the periodontium, or the direct effect of the autonomic nervous system. 🔹Psychosocial factors can modify the periodontal status through behavioural changes regarding oral hygiene, smoking, dietary intake, bruxism and drug use. 🔹Four […]
