<A name="[문서의 처음]"></A> CAUTION :   OrthoMTA root repair material is a powder consisting of fine hydrophilic particles that    set in the presence of water. Hydration of the powder creates a colloidal gel that is     solidified to be a strong impermeable barrier. PRECAUTIONS :  <A name=#80000000></A>OrthoMTA must be kept tightly closed to avoid degradation by moisture.  <A name=#80000000></A>OrthoMTA must be stored in a dry area to avoid degradation by moisture.  <A name=#80000000></A>OrthoMTA must be kept in its sealed packaging prior to use to avoid degradation by moisture.  <A name=#80000000></A>OrthoMTA must be placed intra-orally immediately after mixing with liquid, to prevent dehydration during setting.  <A name=#80000000></A>Excess water will retard curing process. Excess moisture should be removed by a cotton swab.  <A name=#80000000></A>Do not irrigate after placing OrthoMTA root repair material, remove excess water with moist cotton pellet. DIRECTION FOR USE : ORTHOGRADE ROOT CANAL FILLING : 1. <A name=#80000000></A>Prepare the canal for obturation. Successful root canal treatment depends on how thoroughly cleaning the canal. After thorough irrigation the canal is dried and is ready for obturation. 2. <A name=#80000000></A>Dry the canal for an effective filling procedure. Remove the excessive water with   paper points. 3. <A name=#80000000></A>Open the cap of an vial and add 5 drops of sterile water. 4. <A name=#80000000></A>Operate the centrifuge for 5 seconds (3500 rpm). 5. Remove any excess water slightly. 6. Load the OrthoMTA paste into the needle of the OrthoMTA Carrier with gentle    pushing motion.         7. Pre-mixed OrthoMTA paste is introduced into canal system by the OrthoMTA Carrier. 8. Gently plug the OrthoMTA paste into the canal system. 9. Spread the paste against the canal wall and making the space for the OrthoMTA    condenser by the OrthoMTA spreader with reciprocating motion. 10. Ensure that a 0.02 tapered size 25 OrthoMTA Spreader fits passively full length of     the working length. 11. A sterile OrthoMTA Condenser is selected. If a standard .02 taper condenser is     selected it should be at least one size smaller than the size of the largest file taken     to the working length. 12. Withdraw the condenser 0.5mm from the working length if you were able to insert     to this level, to avoid any threat of extrusion past the apical constriction. 13. Resist the 'kick-back' force that is felt, and then retract the rotating condenser whilst     applying gentle force along the canal wall. 14. Apply apical pressure gently but resisting back and forth motion with the 16:1 gear     reduction contra-angle to rotate at approximately 3500-4000 rpm.     Slowly withdraw the condenser while applying gentle pressure on one side of the     canal to help feed the OrthoMTA paste into the canal. Holding in one position too     long causes over-heating and black discoloration of the filling material. 15. Placing a plugger at the canal orifice level. 16. After finishing the canal obturation, post preparation is available immediately. PULP CAPPING : 1. Under a rubber dam, complete a cavity preparation outline using high-speed burs,    under constant water cooling. 2. If caries are present, excavate using a round bur in a hand piece at low speed or    use hand instruments. 3. Rinse the cavity and exposure site(s) with 2.6% - 5% NaOCl. Heavy bleeding may be    controlled with a cotton pellet moistened with NaOCl. 4. PREPARE OrthoMTA ACCORDING TO MIXING INSTRUCTIONS PROVIDED BELOW. 5. Using a small ball applicator, or similar device, apply a small amount of OrthoMTA    over the exposure. 6. Remove the excess moisture at the site with a dry cotton pellet. 7. Apply a small amount of flowable compomer(or an equivalent light-cured resin,    glass-ionomer liner) to cover the OrthoMTA materials, and light cure according to its    instructions. 8. Etch the remaining cavity walls with 34% - 37% phosphoric acid gel for 15 seconds.    Rinse throughly. 9. Dry the cavity gently, leaving the dentin moist, but not wet. Apply bonding material.    Cure according to its instructions. 10. Place composite resin to complete the restoration. Cure according to its instructions. 11. At the next appointment, assess the pulp vitality. Pulp vitality and status should be     assessed radiographically every three to six months or as needed. REPAIR OF PERFORATION SECONDARY TO INTERNAL RESORPTION : 1. Using a rubber dam, debride the root canal system using intra canal instruments and    irrigate with NaOCl. For disinfection place calcium hydroxide paste in the root canal    system for one week. 2. Place a temporary restoration to seal the access opening. 3. After one week, using a rubber dam, remove the Ca(OH)2 from the canal system    using NaOCl irrigation and instrument as needed. 4. Dry the canals with paper points and identify the resorptive defect site. 5. Dry the canal for an effective filling procedure. Remove the excessive water with    paper points. 6. Open the cap of a vial and add 5 drops of sterile water. 7. Operate the centrifuge for 5 seconds (3500 rpm). 8. Remove any excess water slightly. 9. Load the OrthoMTA paste into the needle of the OrthoMTA Carrier with gentle    pushing motion. 10. Pre-mixed OrthoMTA paste is introduced into canal system by the OrthoMTA Carrier. 11. Gently plug the OrthoMTA paste into the canal system. 12. Spread the paste against the canal wall and making the space for the OrthoMTA     condenser by the OrthoMTA spreader with reciprocating motion. 13. Ensure that a 0.02 tapered size 25 OrthoMTA Spreader fits passively full length of     the working length. 14. A sterile OrthoMTA Condenser is selected.

Apply apical pressure gently but resisting back and forth motion with the 16:1 gear     reduction contra-angle to rotate at approximately 3500-4000 rpm. Slowly withdraw     the condenser while applying gentle pressure on one side of the canal to help feed     the OrthoMTA paste into the canal. Holding in one position too long causes      over-heating and black discoloration of the filling material. 18. Placing a plugger at the canal orifice level. 19. After finishing the canal obturation, post preparation is available immediately. ROOT APEXIFICATION: .1.
