Step 1: DIAGNOSIS |
Endo Ice - Refrigerant spray used to diagnose pulpal health. - Applied with a cotton pellet. - Sold in 6oz can. |
|
|
Step 2: Isolation |
Dental Dams- isolate the tooth to provide a clean working environment and prevent tools and debris from falling into patient's mouth. Keeps the working area dry. Brand name is Hygenic Flexi dam: - framed or unframed; latex free; powder free - unframed comes in 6"x6" Dental dam: - latex or non-latex; powder or powder free - comes in 5"x5" and 6"x6" Elasti-dam: - powder free - latex - 5x5" or 6x6" Fiesta: - latex - color coded and fruit scented - 5x5" or 6x6" |
|
|
Step 2a: Isolation with clamps or wedjets |
Wedjets: - latex or non-latex Clamps: - further isolate the tooth and prevent dental dam from slipping - winged or wingless - glossy or matte Fiesta: color coded for organization; matte; winged or wingless |
|
|
Step 3: Access |
Use rotary bur to access the pulpal chamber and then use an orifice opener to flare the coronal portion of the tooth. |
|
|
Step 4: Locate apex/ apical constriction |
Find the working length of the canal using a combination of hand files, radiographs and an apex locator. A size 8 or 10 Hyflex x-file hand file is generally used to create a glide path to the apex. Canal Pro apex locator: - dual impedance technology allows for real time communication between procedure and LCD color display - 94% accuracy - audio and visual feedback - working length determined using this device should be checked with radiograph |

Step 5: Canal Preparation |
Purpose: remove infected tissue, irrigate the canal, shape the canal. Hyflex x-file: - hand files with .02 taper Hyflex NT: - best suited for calcified canals, straight canals, retreatments and removal of gutta percha - .04 taper, 15-60 - .06 taper, 20-40 - 21, 25, 31 mm length - orifice opener .08/25 19 mm length Hyflex CM: - controlled memory allows you to navigate the anatomy of the canal more efficiently - no shape memory - files can be pre-bent - respond to excessive resistance with straightening of the spirals - multi-use; regain shape after heat sterilization - 3x less likely to separate than tradition niti files - same sizes as Hyflex NT Hyflex EDM: - manufactured with electrical discharge machining- underwater spark erosion technique that hardens the surface of the file making it 7x less likely to separate - multi-use due to regenerative abilities - comes pre-sterilized which saves that extra steps for dentists and assistants - variable cross section which contributes to high resistance to cyclic fatigue - quadratic cross section at tip where the most strength is needed - trapezoidal in the middle - almost triangular at the top where the most flexibility is needed Hyflex EDM One File: - can replace several sizes of traditional rotary files due to its variable tapering - size 25; .08 taper for the first 5mm; changes to a .04 taper at the top |

Step 5a: Canal Prepartion |
Endo motor/hand pieces: Canal Pro CL: - cordless endo motor - contra-angle head - 6 head positions - large, easy to read LCD display - 80 min. continuous run time - quick charging time - energy saving mode |
