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 […]
🌟 PERIODONTICS-ORAL SURGERY RELATIONSHIP 📌 POINTS TO PONDER 🔹Teeth should be extracted in an atraumatic manner to conserve alveolar bone. 🔹Clinicians should avoid applying pressure at the crest of the socket to compress the rim of the alveolar bone as it results in the collapse of the remaining buccal plate of the bone and also […]
PERIODONTICS-ORTHODONTICS RELATIONSHIP 📌 POINTS TO PONDER 🔹The effects of orthodontic treatment on periodontium are: – Favors plaque accumulation – Modifies the gingival ecosystem – Gingival recession and hyperplasia – Excessive force causes necrosis of periodontal ligament and alveolar bone. 🔹After 4–6 weeks of regenerative osseous therapy, orthodontic treatment can be initiated. 🔹PAOO is contraindicated in […]
🌟 PERIO-RESTORATIVE RELATIONSHIP 📌 POINTS TO PONDER 🔹Over contoured crowns and restorations accumulate plaque and prevent self-cleansing mechanism of adjacent cheek, lips and tongue. 🔹Overhanging can be removed with the help of files, enamel shavers or EVA prophylaxis system. 📣 Periodontal Considerations In Restorative Dentistry 🔸Margins of restorations 🔸Gingival management for making impressions 🔸Contour of […]
TOPIC: PERIO-PROSTHO RELATIONSHIP 📌 POINTS TO PONDER 🔹Crown-lengthening surgery is the surgical procedure which exposes adequate clinical crown to prevent the placement of the crown margin into the area of the biologic width. 🔹Biologic width is defined as the dimension of healthy gingival tissue, which is attached to the tooth coronal to the crest of […]
