Dental Terminology Lecture

Question 1

caries disease

Answer 1

multifactoral biofilm disease leading to breakdown of teeth

caries disease may progress to become a cavitated lesion. It LEADS to cavities.

Question 2

periodontal disease

Answer 2

multifactoral biofilm disease leading to breakdown of the supporting structures of teeth

Question 3

occlusal disease/disorders

Answer 3

misalignment of teeth and/or how jaws come together leading to caries and/or periodontal diseases and other disorders of the jaw

Question 4

oral infections and cancers- where will you find them

Answer 4

abnormalities of soft tissue of the mouth leading to breakdown of the lining of the mouth (mucosa) and potentially deeper structures

Question 5

locations where caries diseases may occur (4) and what theyre called
what is caries disease

Answer 5

1. on occlusal surface (pit and fissure caries)
2. on the proximal surface - proximal caries
3. on the facial/buccal or lungial/palatal surface = smooth surface caries
4. on expossed root surface = root caries

Question 6

what are the advantages and disadvantages of amalgam restorations?

Answer 6

advantages: easy to place, inexpensive and very durable. can polish after 24 hours and make it nicer
disadvantages: unaesthetic, moderately aggressive preparation (requires more tooth to be taken out for it to and may weaken the tooth- adding inert filling into a hole we make adds no strucutral support to the tooth) . may corrode over time. start to chip on edges where filling meets tooth.

Question 7

advantages and disadvantages to composite/resin restorations

Answer 7

advantages : aesthetic, can be more conservative of tooth structure(dont need as much bulk for strength), may strengthen the tooth ITSELF because it mechanically BONDS to the tooth structure.

disadvantages : harder to place, more expensive, less durable ? (if placed well, very durable, teacher says not less durable if placed well), harder to detect

Question 8

what are PFM, FVC , and FPC?

Answer 8

crown types-
PFM is porcelain fused to metal
FVC is Full Cast Alloy crown - solid metal (gold or mixed metal?)
FPC is full porcelain crown- completely porcelain

Question 9

what are the advantages and disadvantages to metal crown restorations

Answer 9

advantages: strengthens tooth, protects from fracturing, conservative preparation (doesnt require super thick amount of metal around tooth), good marginal seal, very durable
disadvantages: unaesthetic (some cultures like it tho), multiple appointments are needed for it, more expensive than a filling

Question 10

porcelain/ceramic crowns or porcelain/metal crown advantages and disadvantages?

Answer 10

advantages: aesthetic, strengthens the tooth, protects from fracturing, and very durable (ceramic can break so its important the occlusion be adjusted properly so theres not ondo force!!!)
disadvantages: less conservative preparation(needs to be thicker), difficult margins (crown either fits and margins are sealed, or it doesnt fit and it has to be remade) , multiple appointments needed, more expensive than a filling

Question 11

What are the advantages and disadvantages to Veneers? what are veneers made of?

Answer 11

porcelain or “indirect composite” restorations

advantages: more conservative than crowns, thin amount of tooth structure is removed, thin veneer of porcelain put onto the tooth, easily controlled aesthetics, can strengthen tooth because of bonding, done properly can be quite durable
disadvantages: harder to place, more expensive than fillings because of additional work (two appointments needed)

Question 12

what is another term for crown and bridge restorations? what are they made of?

Answer 12

fixed partial denture

Question 13

what are the advantages and disadvantages to metal or ceramic crown and bridge restorations?

Answer 13

advantages: replaces missing teeth, permanent placement, aesthetic, strong and durable

disadvantages : difficult to clean, requires prep of two adjacent teeth, expensive, requires multiple appointments

Question 14

what are the parts to a bridge?

Answer 14

two retainer crowns , connectors (between the teeth), and pontic (tooth replacement tooth)

Question 15

what are the advantages and disadvantages to an implant?

Answer 15

advantages: most like a regular tooth, clean/maintain regularly, aesthetic, permanently placed, replaces missing tooth
disadvantages: MOST expensive restoration option, requires multiple surgeries and multiple appointments over months, no periodontal ligament

Question 16

what are the advantages and disadvantages to a removable partial denture / bridge?

Answer 16

advantages: most conservative of tooth structure, least expensive option, replaces missing teeth
disadvantages: food gets stuck inside, have to take out overnight for cleaning, bulky, impacts speech, needs periodic adjusting

Question 17

what goes into a hard tissue exam?

Answer 17

(part of step 3 of oral diagnosis and treatment planning - odtp- process, will learn more)

• thorough visual exam with a mirror
• tactile examination with a pigtail explorer
• radiographic image review (show to patient and get a better understanding)

Question 18

what are PA and BW’s

Answer 18

periapical radiograph: for assessing heath of tooth, nerve center, is there abnormalities at apexes?

bitewing radiograph: see bone of both jaws, best for asessing whether theres caries lesioms between teeth, and the health of periodontal bone around the teeth

Question 19

what is CBCT

Answer 19

cone beam computed topography - 3d reconstruction , can also be of the whole skull, or just parts in different planes. can get a panoramic image, cross sectional, saggital, axial as well. versatile but high radiation so not doing often. Pano and FMX are better for routine

Question 20

radiopaque and radiolucent

Answer 20

radiopaque indicates higher density- the whiter, the more dense. radiolucence indicates lower density, air is black, etc.
-caries are more radiolucent because of decalcification

Question 21

new vs recurrent caries

Answer 21

new is at an unrestored site. recurrent or secondary occurs at the margins of existing restorations

Question 22

what is an open crown margin?

Answer 22

space between tooth and crown, often found w decay at the crown margins

Question 23

what is rarifying osteitis

Answer 23

bone loss, applies to periapical radiolucency

Question 24

how can radiograph show periodontal disease

Answer 24

loss of alveolar bone height(?), loss of crestal cortical bone (tip of alveolar bone / top part), widening of the periodontal ligament space (defined radiolucence border along normally shaped root)
