Q

Diagnostic conclusion: the tooth displayed symptoms of lingering pain

A

Irreversible pulpitis

24
Q

Diagnosis: this type of cyst develops at or near the root of a necrotic tooth , they develop as an inflammatory response to pulpal infection and necrosis if the pulp

A

Periridicular cyst

25
Q

Diagnosis: a decrease in living cells within the pulp causes fibrous tissue to take over the pulpal canal

A

Pulp fibrosis

26
Q

Diagnosis: the tooth may as be referred to as non vital, describes a tooth that does not respond to sensory stimuli

A

Necrosis

27
Q

Procedures: performed on a tooth that has an acute apical abscess usually has severe pain. Incision is made in the gum to drain infection

A

Incision and drain

28
Q

Abnormal passage or drainage leading from an abscess to the surface of the skin

A

Fistula

29
Q

Procedures: attempt to save the pulp, calcium hydroxide is placed over an exposed or nearly exposed pulp to encourage the formation of dentin

A

Indirect pulp capping

30
Q

Procedures: Indicated when the pulp has been slightly exposed

A

Direct pulp calling

31
Q

Procedure: involves removal of the coronal portion of an exposed vital pulp, used to preserve the vitality of the remaining portion of the pulp within the root of the tooth indicates for primary teeth, teeth with deep carious lesions and emergencies

A

Pulpotomy

32
Q

Also referred to as rct, this procedure involves the complete removal of the dental pulp

A

Pulpectomy

33
Q

Instruments: working ends positioned at an angle which helps to locate the canal openings

A

Endodontic explorer

34
Q

Instruments: similar to spoon excavator but has much longer shank

A

Endodontic spoon excavator

35
Q

Instruments: used to obturate the canals condense and adapt gutta percha into canals

A

Spreaders- lateral pluggers compress down

36
Q

Instruments: paddle end for placement and shaping of temp restoration, rod shaped can be heated for placement or removal of gutta percha

A

Glick number 1

37
Q

Instruments: twisted design for initial debridment of canal and during later stages of shaping and contouring the canal

A

K type files

38
Q

Instruments: has greater cutting efficiency because of its design so cutting occurs in the pulling stroke used for final enlargement of canal

A

Hedstrom file

39
Q

Instrument: similar to k file but the cutting edges are further apart, used to remove dentin structure and smooth and increase size of canal

A

Reamer file

40
Q

Instruments: thin, flexible, tapered tiny projections used to remove vital inflamed pulp tissue (extirpation) from the canal. Can also remove cotton pellets and paper points

A

Broaches

41
Q

Rotary burs: football shaped end and very long shank, used to enlarge walls of pulp chamber ( cutting edge is on sides not end)

A

Gates glidden

42
Q

Rotary burs: long blades, parallel with non cutting ends, used when tooth requires a post preparation for placement of final restoration

A

Pesso files

43
Q

Paper points do what

A

Absorb and dry irrigation solution out of canals

44
Q

Medicaments: facilitates the removal of materials from the canal and provides tissue dissolution, bleaching, deodorizing, and hemmorhage control

A

Irrigation solution

45
Q

Made from rubber material, solid at room temp but soft when heated used to obturate canals

A

Gutta-percha points

46
Q

Cement type material that seals infilled voids during obturation

A

Root canal sealers

47
Q

Used in low speed to place sealed and cements into canal

A

Lentulo spiral

48
Q

Can reduce number of radiographs taken to determine working length using

A

Electronic apex locator

49
Q

Purpose of ___ and ___ is to remove bacteria, smooth and shape the canal so filling material can be completely adapted

A

Debridement and shaping

50
Q

Objective is to place a fluid tight seal in the canals form apical tip to coronal surface to prevent re entry of microorganisms (has to be 1mm within the working length )

A

Obturation

51
Q

____ may be caused by persistent infection, improper measurement of canals, severely curved roots, perforation of canal, fractured roots, extensive root resorption, pulp stones

A

Endodontic failure

52
Q

To surgically remove the apical portion of the root

A

Apicoectomy

53
Q

Performed to remove pathological soft tissue around the root of the apex

A

Apical curettage

54
Q

Root end filling, completed when the apical seal is not adequate

A

Retrograde restoration

55
Q

Remove one or more roots of a multi rooted tooth without removing the crown mostly done on max molars

A

Root amputation

56
Q

The root and the crown are cut length wise and removed, mostly done on mand molars

A

Hemisection
