Oral Diagnosis and Radiology Quiz

Digital Radiography

• Digital radiography uses an electronic sensor instead of x-ray film to produce images that can be examined on a computer screen in a short time.

Panoramic Radiographies (OPTG)

• A type of extraoral radiography that shows both jaws, bony part of TMJ, and all upper and lower teeth at the same time.
• Provides ease of use, especially in patients and children who have difficulties in opening their mouth.
• No film is placed in the mouth during the procedure.
• Preferred in today's dentistry as it fits the entire mouth into a single image, making it easier to detect many problems.

Bite-Wing Radiographies

• Used to evaluate the relationship between the crowns of the teeth and the height of the alveolar bone and the cemento-enamel junction.

Radiography Indications

• Caries detection and evaluation
• Imaging pathologies resulting from infection that may occur around the teeth and roots in patients complaining of pain
• Traumatic dental injuries
• Detecting eruption problems
• Developmental anomalies
• Unexplained color changes of teeth
• Before planning for orthodontic treatment
• In the presence of facial swelling
• For evaluation of prosthetic purposes
• For surgical evaluations

Types of Dental Radiographies

• Intraoral radiographs
• Occlusal radiography
• Periapical radiography
• Bite-wing radiography
• Extraoral radiographs
• Panoramic radiography / OPTG
• Cephalometric radiography
• Dental Volumetric Tomography

Periapical Radiography

• Used when detailed images of one or more teeth are desired
• Evaluates the crown and root part as a whole and visualizes the surrounding bone tissue
• Conditions of permanent teeth below the milk teeth can be evaluated
• Used to evaluate infections in the teeth, pathologies resulting from trauma and root canal treatment stages

Oral Diagnosis and Radiology

• Examines intraoral and head-neck area tissues and organs systematically
• Evaluates all changes in these structures clinically and radiographically
• Plans treatments to be performed and directs patients to the relevant departments
• Provides education at undergraduate and graduate levels.

Importance of Radiographic Examination

• An indispensable method used for diagnosis, treatment planning, and post-treatment control
• Helps detect decay, bone loss, and root canal problems that cannot be noticed during examination
• Aids in treatment planning in orthodontic treatment and implantology.
