Endo

Question 1

Tooth #8

Answer 1

Question 2

Asymmetrical Preparation

Cause: Excessive removal of tooth structure on one of the marginal ridges. Not accurately locating the cingulum notch

Answer 2

Question 3

Over-Extended Access Prep Incisally

Cause: Extended prep too far incisally

Under-extended Access Prep Apically

Cause: Failue to extend prep to cingulum notch

Answer 3

Halfway up the triangular ridge/slightly distal

Answer 7

Question 8

Access: Dot 2

Just distal to the buccal groove

Answer 8

Question 9

Access: Dot 3

Halfway up the triangular ridge/slightly distal

Answer 9

Question 10

Access point

Penetrate the central pit to a depth of +4 mm

Answer 10

Question 11

Access:

connect the penetration point to the DB dot-dot not impinge the DB cusp triangular ridge

Answer 11

Question 12

Access:

Connect DB dot to the MB dot

Answer 12

Question 13

Access:

Connect the MB dot to the P dot-parallel the mesial proximal surface when connecting the dots

Answer 13

Question 14

Access:

Connect the P dot to the initial penetration point- DO NOT impinge on the ooblique ridge

Answer 14

Question 15

Access:

Remove the remaining roof of the pulp chamber

Answer 15

Question 16

Excessive Flaring

Cause: failure to keep the long access of the bur perpendicular to the occlusal plane

Answer 16

Question 17

Under-extend prep

Remedy: Follow the chuti method-place the dots in the correct position

Answer 17

Question 18

Access not over pulp Chamber

Answer 18

Question 19

Lack of straight line access

Remedy: selective filing to remove dentin triangle

Answer 19

Question 20

Hornectomy

Failure

Cause: failure to maintain the depth of the bur resulting in partial removal of the roof of the pulp chamber

Remedy: maintain a depth of 4mm relative to the central pit while connecting the dots

Answer 20

Question 21

Severely Gouged Floor of chamber (near perforation)

Cause: Taking the bur too far passed the roof of the chamber…lack of knowledge of the tooth’s morphology

Answer 21

Question 22

Perforation

Failure

Answer 22

Question 23

Answer 25

Question 26

Wave One Gold

Answer 26

Question 27

Wave one Gold - Degresive tapers

Answer 27

Question 28

Apical Control Zone

Answer 28

Question 29

Streamlined Technique

Answer 29

Question 30

Vortex Orifice opener

Answer 30

Coronal Third Prepartion Dentin Triangle-use orifice opener in a brush stroke motion (away from furcation) to remove to gain straight line access Use orifice opener in a brushing motion...brushing away from the furcation on removal

Question 31

Glidepath

Answer 31

a smooth radicular tunnel from canal orifice to phsiologic terminus (foraminal constriction) Reduce torsional stress Reduce flexing stress Reduce taper lock

Question 32

Proglider

Answer 32

One single mechanical glide path file progressive tapers from 2% to 8% over its length offers a smoother "glide path" trasition metallurgically enhanced utilizing M-wire technology controlled, smooth, inward cutting action

Question 33

Shaping objectives

Answer 33

continously tapering funnel from the access cavity to apical foramen root canal preparation should maintain the path of the original canal apical foreman should remain in its original position apical opening should be kept as small as practical

Question 34

Pass Stroke

Answer 34

pass = 3 strokes stroke = 2-3 mm file insertion (or until it binds)

Question 35

Vortex on Torque

Answer 35

Question 36

Proglider on Torque

Answer 36

Question 37

Waveone on Torque

Answer 37

Question 38

Working Length

Answer 38

1. Remove file 2. measure the tip of the file to the rubber stopper 3. record the length and set everything to that measurement

Question 39

Leur-Lock Syringe

Answer 39

Question 40
