• remove excess
• document

Question 2

what is the principle of the bleeding index

Answer 2

measure severity of gingival inflammation

0 - normal
1 - mild inflammation
2 - moderate inflammation
3- severe inflammaton

Question 3

basic forms of periodontal disease

Answer 3

gingivitis
- inflammation, red, swollen gingiva

early periodontitis
- plaque beginning to collecet, infection with perio pockets forming

moderate periodontitis
- spread of inflammation, loss in bone, loosening teeth, receding gums

advanced periodontitis
- inflammation of gingiva and surrounding tissues, sever bone loss

Question 4

mobility scores

Answer 4

0 - normal
1- slight mobility
2- moderate mobility
3- extreme mobility

Question 5

types of nonsurgical periodontal disease treatment

Answer 5

dental prophylaxis
- complete removal of caalculus, soft deposits, plaque, stain

scaling and root planing
- remove remaining particles of calculus and necrotic cementum

gingival curettage

antimicrobial and antibiotic agents
- tetracyclin

Answer 6

excisional surgery
- gingivectomy: removal of diseased gingival tissue
- gingivoplasty: surgical reshaping and contouring of gingival tissues

protect newly forming tissues
minimize pain
prtect from trauma while eating
supports mobile teeth

Question 8

advantages of hand scaling vs ultrasonic scaling

Answer 8

hand scaling

- more control
- area-specific

ultrasonic
