25 Questions

1. Bony wall that divides 2 spaces - radiopaque

2. Occurs frequently due to the high concentration of water in cells.

3. A form of secondary radiation - the result of x-rays that has been deflected from its path by an interaction with matter.

4. Continues from ramus; radiopaque band

5. Dental x-ray machines operating 70 kVp or below: minimum 1.5 mm aluminum filtration - Dental x-ray machines operating above 70 kVp: minimum of 2.5 mm. of aluminum filtration.

6. Posterior to mandibular third molar

7. Tubes within maxillary sinus that carry nerves - blood supply - radiolucent band with boundary of two radiopaque cortical bony lines

8. Closed - pointed cone-high production of scatter - not used any longer.

9. Rounded prominence that appears radiopaque

10. The x-ray photon is deflected from its path during its passage through matter

11. Time between exposure to ionizing radiation and the appearance of observable clinical signs.

12. Sievart

13. 8 inch and 16 inch; longer are preferred due to less divergence of beam - open ended and lead lined.

14. Hollow space - cavity that appears radiolucent

15. Used to decrease voltage from the incoming 110- or 220-line voltage to the 3 to 5 volts used by the filament circuit.

16. Gray

17. Coronal part of alveolar bone - between teeth - cortical bone - radiopaque

18. Rate which exposure to radiation occurs and absorption occurs (more damage occurs with high dose due to rapid delivery and does not allow for repair)

19. Quantity of radiation received or total amount absorbed (more damage with tissue absorbing large quantities of radiation)

20. Cortical bone - radiopaque band above maxillary incisors

21. Mature bone - muscle - nerve

22. Hole in bone below mandibular premolars - blood supply to lower lip exits here; radiolucent; often misdiagnosed for periapical pathology

23. Intersection of maxillary sinus and nasal cavity - radiopaque - cortical bone; above maxillary canine.

24. The measurement of electrical force that causes electrons to move from a negative pole to a positive one. Measured in volts (V) or kilovolts (kV)

25. Tube that passes through bone - contains nerve canals/blood vessels/and appears radiolucent
