Week 5

Question 1

Assessment of oral biofilm

Answer 1

location, amount, and extent (generalized or localized)

Question 2

acquired pellicle

Answer 2

nonminerlized layer, unstructured, homogeneous layer adhere to tooth surfaces

Question 3

oral biofilm

Answer 3

cellular, non mineralized layer, dense, transparent, highly organized mass of bacterial colonies inter closed in matrix

Question 4

materia alba

Answer 4

cellular, non mineralized layer, loose deposit of microbes, skins cells, broken down food, white to yellow apperance

Question 5

food debris

Answer 5

cellular, non mineralized, unstructured particles that remain in the out after eating

Question 6

Extrinsic stain

Answer 6

cellular, mineralized or non, discoulorations on external tooth via pellicle, biofilm or calculus

Question 7

supragingaval calculus

Answer 7

cellular, mineralizza, permette with hard calcium phosphate, covered with biofilm, on grown, yellow-white ish

Question 8

Subgingival calculus

Answer 8

cellular, mineralized, adheres to tooth under gum, organic martix of bacteria w hard calcium phosphate, been - back covered w biofilm

Question 9

progression of periodontal disease

Answer 9

1) Pellicle formation
2) Bacterial biofilm formation (mineralization of biofilm leads to calculus formation, biofilm overlays calculus)
3) Inflammation (leading to pocket formation)
4) Activation of inflammatory response
5) Ulcerated sulcular epithelium with an increase in crevicular fluids, along with continued inflammation
6) Disease may progress to periodontitis if JE migrates away from CEJ and bone destruction occurs
7) Presence of tooth mobility and tooth loss can occur with further destruction

Question 10

non plaque induced gingival diseases

Answer 10

viral infections, fungal infections, skin diseases, allergic reaction, mechanical trauma, habits, occlusal forces

Question 11

Halitosis assessment (mesurent, assessment, treatment)

Answer 11

• heliometers; oral chroma
• quantify intensity exam, soft and hard deposits, oral hygiene , determine cause
• Improved oral hygiene, tongue cleaning, diet, antimicrobial mouth rinses, medication

Question 12

Endogenous

Answer 12

Originated from within the tooth (origin)

Question 13

Intrinsic

Answer 13

within the tooth substance and cannot be removed by polishing (location)

Question 14

exogenous

Answer 14

originated from outside of the tooth (origin)

Question 15

extrinsic

Answer 15

Occur on external surface of the tooth - can be removed by polishing (location)
