1. Marginal ridge: Ridge or elevation of enamel forming the margin of the surface
of a tooth; specifically at the mesial and distal margins of the occlusal surfaces of
premolars and molars, and the mesial and distal margins of the lingual surfaces of
incisors and canines.
2. Triangular ridge: An elevation of enamel that descends from the cusp into the
middle area of the occlusal surface
3. Transverse ridge: Ridge formed by joining of two triangular ridges crossing
occlusal table transversely or from buccal to lingual outline
4. Oblique ridge: Transverse ridge that crosses occlusal table obliquely from mesi-
olingual to distobuccal on most maxillary molars
5. Bifurcated: Single tooth with 2 roots
6. Cementum: Specialized, calcified connective tissue that covers the anatomic root
of a tooth
7. CEJ (cementoenamel junction): where the cementum and enamel meet
8. Cingulumn: Small bump near cervical third on lingual side
9. Enamel: hard, outermost layer of a tooth
10. DEJ (dentinoenamel junction): Where the dentin and enamel meet
11. Fissure: deep groove, incomplete closure of lobes
12. Fossae: Major depression on occlusal surface of tooth
13. Periodontal Lingament (PDL): Fibers that connect tooth to bone
14. Periodontium: consists of the bone and soft tissues that surround and support
the teeth
15. Pulp: The tissue that contains the blood vessels and nerves of a tooth. Feels
pain
16. Sulcus: Unattached free gingiva - gingiva crevice
17. Pit: A small pinpoint depression on the surface of a tooth that is caused by the
failure of the union of the developmental grooves
18. Cusp: Major elevation or convexity on the masticatory surfaces of canines and
posterior teeth
19. Ridge: a linear elevation of enamel found on the tooth
20. Clinical crown: That portion of the tooth that is visible in the oral cavity
21. Anatomical crown: Portion of the tooth that is covered with enamel (non-visible)
22. Dentin: Dense tissue forming the bulk of a tooth
23. Function of anterior teeth: Tear/ cut food without heavy force
24. Function of posterior teeth: Crush/ grind food with heavy force
25. Tooth Numbering systems: universal/national numbering system, federation
dentaire internationale (fdi, ISO), palmer notation system
26. Attrition: Wearing away tooth structure from Tooth to tooth contact
27. Abrasion: Wearing away tooth by brushing habits, mechanical motions

28. Abfraction: Wearing away tooth structure by Uneven forces at gingival margin
29. Erosion: Wearing away tooth from bacteria; acids and diet
30. Acellular cementum: Cannot be repaired. Located at cervical third of apex
31. Causes of Trauma to pulp: Air, temperature, pressure, materials
32. Cellular cementum: Can be repaired. located at apical third
33. Base: Thick layer at pulpal floor that Provides thermal insulation. Needed if there
is less than 0.5mm of dentin remaining
34. Liner: Thin layer placed at pulpal floor to protect against chemical irritation. Can
be used as a pulp cap
35. Direct supervision: Level of supervision in which the dentist is physically pre-
sent when the dental auxiliary performs delegated functions ( dentist must be in the
facility)
36. How often does an EFDA license get renewed?: Every 2 years
37. When does an EFDA license expire?: Every 2 years bi annually ; March 31st
ODD years (2023,2025)
38. How many CEs per license period?: 10 CEs (every 2 years)
39. Change of address report within: 10 days to state board
40. EFDA permissible functions: Placing/ contouring fillings, coronal polishing,
sealants, fluoride varnish, impressions for some appliances (not final appliances),
temporary crowns, indirect pulp cap, bases and liners, placing matrix and dental
dam
41. MSDs (Musculoskeletal Disorders): Painful conditions that affect both mus-
cles and bones, such as neck or back pain and carpal tunnel syndrome due to poor
posture/ positioning
42. Operating zones right hand: 8-12: operator zone
12-2: static zone
2-5: assistant zone
5-8: transfer zone
43. Parts of an instrument: handle, shank, working end
44. Handle: Grasp of the instrument
45. Shank: Connects working end and handle
46. Working end: functional part of the dental instrument
47. Compactor instruments: Condense and pack filling material
48. Carver instruments: Remove excess filling material
49. Burnisher instruments: Rub, blend, smooth filling material
50. Rotary instruments: Used to finish and polish filling material
51. amalgam carvers: Hollenbach and Discoid/ cleoid
52. Falcrum: Rest finger - controlled movement of instrument using ring finger for
patient and operator safety
