Endodontic Instruments an der Vilnius University

• Cassette = hold instruments during sterilization and storage

• Mouth mirror

• General purpose explorer

• Periodontal probe

• Cotton forceps = used for various functions during examination procedureè Holding cotton pellets = cold testing
  è Cotton rolls = controlling moisture for electric pulp test

• Other isolation materials:

1. Includes special instruments in addition to those in examination and diagnosis kit:

   • DL16 = double ended, long tapered tines at varying angles

   • Spoon excavator = used to remove Debris from pulp chamber and canals

     è extra long shank compared to standard spoon (used in restorative dentistry)

   • Glick #1 = used for placement of materials such as temporary restorations)

     è Paddle end = placement of materials

     è Plugger end = removal or condensation of gutta-percha

   • Rod shaped plugger = may have markings to indicate 5mm increments

   • Other aspects of procedure include:

     è Sparula
     è Millimeter ruler
     è Device for holding filesè 

   • Scissors
     è Hemostats
     è Bur block with burs
     è Syringes

• Scalpel handle + blade

• Small, curved hemostat

• Latex drain

• Needle holder

• Suture material

• 25-cc irrigation syringe

• 18-gauge irrigation needle

• Sterile saline

• Surgical suction tip

1. Instruments included with Cleaning + Shaping Tray with addition of paste ingredients + plastic instrument

1. Purpose of Canal preparation (cleaning + shaping) = mechanically debride and allow chemical disinfection, followed by sealing

   of spaces

1. Basic categories of metal = used to construct root canal-shaping instruments

   -> Stainless steel + Nickel-Titanium

   Instruments with different properties
   Clinician should select instrument type based on Physical properties needed for procedure + cost

primarily composed of carbon, iron and nickel
Relatively inflexible -> renders them less adaptable to canal

curvatures

composed of 55% nickel + 45% titanium (can vary) Instruments with different properties
More flexible + adapt more readily to fine, curved canals
Have no advantage over stainless steel files in straight + irregular canal spaces
Due to unique crystalline structure + phase change capability = most of these files have shape memory

Fabricated from Blank wire by: Grinding, twisting or combination of both
Results in different Instrument designs, physical characteristics and working properties

produced by blank wire in lathe Grinding it to specific design

produced by twisting or grinding a square or triangular tapered wire to form cutting edges along the length of the shaft

one end of blank is fixed in lathe
other end is allowed to rotate until desired design shape
