Dental Radiology Exam Study Guide with Complete Solutions

Dental Radiology Exam Study Guide with Complete Solutions Radiolucent - Answer️️ -Dark-to-black areas on a processed radiograph that result from the passage of radiant energies through less dense/soft areas. Examples include pulp, dental caries and foramen. Radiopaque - Answer️️ -Light-to-white areas on a processed radiograph that result from radiant energies penetrating more dense structures. Examples include amalgam and gutta percha. amalgam restoration - Answer️️ -A form of dental restoration that uses a combination of two or more metals, one of which is mercury; a blend of powdered metal alloy and mercury to produce a restorative material. composite restoration - Answer️️ -A form of dental restoration that uses resin restorative material that is hardened by chemical or light curing. Condyle of the mandible - Answer️️ -A ball like structure that forms the hinge between the maxilla and the mandible and is a part of the temporomandibular joint Panoramic radiograph - Answer️️ -An extraoral radiograph taken to expose the maxillary and mandibular arches, tempormandibular joints and associated anatomy on a single film. ©SOPHIABENNET@2024/2025 Tuesday, August 20, 2024 10:21 AM 2 Cephalometric radiograph - Answer️️ -An extraoral radiograph of the head that is used in orthodontic and prosthodontic dentistry to show a profile of the patient's head. Computed Tomography (CT) - Answer️️ -An imaging technique that isolates an area or "slice" of tissue while blurring out other structures. Ramus - Answer️️ -The vertical portion at each end of the mandible that are perpendicular to the body of the mandible. body of the mandible - Answer️️ -The curved horizontal part of the mandible that extends from one ramus to the other mandible - Answer️️ -A single bone which makes up the lower jaw and is the only movable bone in the skull. - Made up of the condyloid process, the coronoid process, the ramus, the body of the mandible, the alveolar process, and the mental protuberance. Maxilla - Answer️️ -Two bones that form the upper jaw and part of the palate, joined together at the midline by the maxillary suture Alveolar process - Answer️️ -The extension of the maxilla and mandible that surrounds and supports the teeth to form the dental arches. - Upper aspect of the body of the mandible - Appears radiopaque on maxillary molar peroapical radiographs Midsagittal plane (midline) - Answer️️ -Imaginary vertical plane that equally separates the body into right and left halves. ©SOPHIABENNET@2024/2025 Tuesday, August 20, 2024 10:21 AM 3 orbit - Answer️️ -eye cavity Frankfort Plane - Answer️️ -Imaginary line from the bottom of the eye socket to the auditory meatus Junction of lateral wall of nassal fossa and the wall of the maxillary sinus - Answer️️ -Inverted Y located above the maxillary canine in the canine- premolar region. Appears radiopaque on maxillary canine periapical images. Periapical exposure - Answer️️ -Pertaining to around the apex; radiograph that exposes the entire tooth and surrounding tissues. Maxillary sinus - Answer️️ -Large cavities located superior to the maxillary premolar and molar teeth. Appear radiolucent on maxillary premolar and molar periapical images. The outline of the denser tissue (the floor of the sinus) appears radiopaque. - Roots of maxillary 1st molar always appear to penetrate sinuses but rarely do. Nutrient canals - Answer️️ -small passageways through bone that contain blood vessels, nerve tissue, and lymphatic tissue that supply the teeth. pulp tissues - Answer️️ -nutrient canals once they enter the to
