Q

Lack of straight line access

Remedy: selective filing to remove dentin triangle

A

Q

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

A
21
Q

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

Q

Streamlined Technique

A
30
Q

Vortex Orifice opener

A

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

31
Q

Glidepath

A

a smooth radicular tunnel from canal orifice to phsiologic terminus (foraminal constriction)

Reduce torsional stress

Reduce flexing stress

Reduce taper lock

32
Q

Proglider

A

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

33
Q

Shaping objectives

A

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

34
Q

Pass

Stroke

A

pass = 3 strokes

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

35
Q

Vortex on Torque

A
36
Q

Proglider on Torque

A
37
Q

Waveone on Torque

A
38
Q

Working Length

A
  1. Remove file
  2. measure the tip of the file to the rubber stopper
  3. record the length and set everything to that measurement
39
Q

Leur-Lock Syringe

A
40
Q

Obturation

A

use of materials and techniques to fill the entire root canal system in a three dimensional manner

41
