Core-X flow is Dual-Cure Build-up Material and Cement for Endodontic Posts.
Core-X flow consists of two-components, base and catalyst, which when mixed form a dual-cured, highly filled, composite resin core build-up and post cementation material. Core-X flow uses a biocompatible urethane resin and is supplied in a tooth-colored shade which is ideal in situations where esthetics and show-through of core are of primary concern.

Urethane Dimethacrylate
Di- & Tri-functional Methacrylates
Barium Boron Fluoroaluminosilicate Glass
Camphorquinone (CQ) Photoinitiator
Silicon Dioxide
Benzoyl Peroxide

Vital or non-vital tooth core build-up (replacement of existing restorations and/or lost tooth structure) as a base prior to fabricating an indirect restoration.
Cementation of endodontic fiber-posts.

KEY Specifications

Working Time at body temperature (37 °C) – for manipulation/post seating after intraoral placement 40 seconds Working Time at room temperature (22 °C) – for application after start of mix 1 minute 30 seconds Setting Time Light Cure 20 seconds1 (3 mm depth) Setting Time Self Cure (catalyst initiated) 2-3 minutes Precautions This product is intended to be used only as specifically outlined in the Directions for Use. Any use of this product inconsistent with the Directions for Use is at the discretion and sole responsibility of the practitioner. Contact with saliva and blood during compo-site placement may cause failure of the restoration. Use of rubber dam or adequate isolation is recommended. Wear suitable protective eyewear, mask, clothing and gloves. Protective eyewear is recommended for patients. Syringe should be tightly closed by replacing the original cap immediately after use. core·X flow is intended to be used as a dual-cure product. To obtain optimal curing follow the step-by-step instructions. Self-cured, dual-cured and light-cure methods are integrated into the procedural steps. core·X flow should be mixed in equal volumes directly through the supplied mix tips for optimum performance. Variations from this 1:1 ratio may adversely affect working time and compromise final physical properties. Dispensing and mixing other than through the supplied mixing tips is not recommended. core·X flow should extrude easily. DO NOT USE EXCESSIVE FORCE. Excessive pressure may result in unanticipated extrusion of the material or cause syringe rupture. core·X flow when used for post-cementation has a working time of only 40 seconds! Prepare and organize the necessary materials and instruments to allow a fast insertion of the post. Eugenol-containing dental materials should not be used with core·X flow because they may interfere with hardening and cause softening of the polymeric components of the materials. Working Time at body temperature (37 °C) – for manipulation/post seating after intraoral placement 40 seconds Working Time at room temperature (22 °C) – for application after start of mix 1 minute 30 seconds Setting Time Light Cure 20 seconds1 (3 mm depth) Setting Time Self Cure (catalyst initiated) 2-3 minutes Variable in-vitro data exist regarding use of light-cured-only adhesives without Self-cure Activator in conjunction with dual-cured or self-cured composite restorative materials such as core·X flow in limited or no light-curing applications. Chemical/product incompatibility may adversely affect product efficacy, leading to premature restoration failure. As with any dual-cure resin system, the use of a dual-cure adhesive system can shorten working time. This effect should be investigated in the laboratory prior to clinical use. The core·X flow is a light-cured material. Therefore, it should be protected from ambient light. Proceed immediately once material has been placed.

Directions To USE

Cleaning and Preparation of Tooth Finish preparation by removing existing restorations and/or caries. Clean freshly cut enamel and dentin with water spray and air dry. Do not desiccate dentin. Place pin, post or matrix as needed. Pulp protection, Tooth Conditioning/Dentin Pretreatment, Adhesive Application Once the surfaces have been properly treated, they must be kept uncontaminated. Proceed immediately to placement of core·X flow. Dispensing and mixing core·X flow dual-barreled syringe If refrigerated prior to use, remove from refrigerator and bring to room temperature. Remove syringe cap and dispense and discard a small amount of material from the dual-barreled syringe. Be sure material is flowing freely from both ports. Holding syringe vertically, carefully wipe away excess so base and catalyst do not cross-contaminate and cause obstruction of the ports. Save syringe cap for replacement following use. Install a mixing tip on the cartridge by lining up the v-shaped notch on the outside of the mix tip with the v-shape notch on the syringe flange. Turn colored mix tip cap 90 degrees in a clockwise direction to lock in place on syringe. Gently depress syringe plungers to begin the flow of material. DO NOT USE EXCESSIVE FORCE. If force is encountered, remove syringe from operating field, remove and discard mix tip. Check for obstruction and confirm material is flowing from both syringe barrels. Wipe barrels and install new mix tip as outlined above. Dispense a small amount through the mix tip onto a mixing pad and discard. Placement of core·X flow core·X flow produces a syringable mixed consistency for direct placement using the dualbarreled syringe and a banded matrix retainer or clear crown form. Alternatively, mixed material may be expressed onto a clean paper pad and manually placed with the operator’s placement instrument(s) of choice. Working time of mixed material at room temperature (22 °C/72 °F) is approximately 1’30” (one minute thirty seconds) when protected from ambient light. Elevated oral temperatures and/or contact with dual-cure adhesives may shorten work time. Any of the following placement techniques are acceptable. The preferred method is to use both visible light- and chemical self-cure: 1. Visible Light-Cure Place mixed material directly in 2-3 mm increments and light-cure increment for 20 seconds1 . 2. Chemical Self-Cure Place large increment(s) or load mixed material into a clear crown form and seat onto the preparation. Allow to self-cure approximately 2-3 minutes. Visible light-curing1 of external surface is optional, but advisable. 3. Dual-Cure After placing the first 2-3 mm increment, and visible light-curing for 20 seconds1 , large increments may then be placed or material loaded into a clear crown form, seated onto the preparation and allowed to self-cure. Visible light-curing1 of external surface is optional, but advisable. Finishing the core·X flow After initial self-cure set and removal of matrix, a surface light-cure of the material for an additional 20 seconds1 is recommended. Initial crown preparation (gross reduction) may begin immediately using rotary instruments.
