Dental Etching Gel, Luting Cement & Bonding Liquid | Made in the UK

PRODUCT DESCRIPTION: Carebond is one component bonding liquid for methacrylate restorations containing dispersed acrylates and monomers and initiators in volatile base. It can be used following acid etching with phosphoric acid..

INDICATION:

–           Bonding for direct & indirect light cure composite restorations/compomers.

–           Adhesive for core build up materials repair restorative for composites, compomers, ceramic veneers and all ceramic restorations.

–           Treatment of hypersensitive cervical erosions.to use as varnish to protect glass ionomers sealer for crack, deficiencies of teeth and restorations.

–           Bonding of self, light cure and dual curing composites luting of posts using dual cure composites

CONTRAINDICATIONS: In rare cases (delayed and long term) product may cause hypersensitivity or allergy in some people. If such reactions are experienced, discontinue use of the product and refer to physician.

CAREBOND:

Contains reactive monomers and contents of retraction cord impregnated with alum salts may cause premature polymerization and thus the cord may be difficult to be removed.

Carebond should be used sparingly on calcium hydroxide liners as the solvent may cause weakening.

Do not use eugenol based cements in conjunction with Carebond and composite as it impairs setting.

INSTRUCTIONS FOR USE:

Operating site and teeth should be isolated well to prevent contamination by oral fluids. Use of rubber dam is advised.

PULP PROTECTION:

It is advisable to line the deepest part of the cavity with a dot of Calcium Hydroxide liner such as Calbase LC or Carecal. Do not use Eugenol based liners.

SANDWICH TECHNIQUE:

If the cavity is deep then line the deepest part of the cavity with the hard setting calcium hydroxide liner. Then line the rest of the cavity with glass ionomers liner such as Restomer Base. The liner can be laid in thick layer reaching the enamel-Dental junction. This will reduce the thickness of composite and help to achieve full light cure throughout easily. Also the reduced bulk assists in reducing pressure caused by expansion and contraction of composites. Following this the whole area can be acid etched including the glass ionomers as mentioned below.

TECHNIQUE OF ETCHING USING COMPOSITE BOND

ACID ETCH OF THE ENAMEL

Attach the supplied to acid gel syringe.

Apply the gel to the cavity extending some 2mm beyond the margin (This is particularly important for additional retention in class IV cavities). The gel should be applied with the gentle wiping action.

Place a small quantity of etching gel on to a cotton bud. Ensure that needle is securely locked into the leur syringe. By gentle pressure extrude the gel directly on to tooth. Start with enamel cavity margins and work around to sides and base of the cavity. The blue colour of the gel will assist in controlling the area of action. Allow to etch for 25 secs from the start of the application. Do not allow the gel to dry out . Wash away the gel with jet of water and then wash with the air/water spray until all the gel has been removed. Dry the etched area. Ensure that enamel is dried until chalky dull appearance. The dentine should not be totally dried but moist but not very wet. Re-etching may be required if the enamel is not frosty in appearance. Isolate the tooth and prepare for application of bonding liquid.

APPLICATION OF BONDING SOLUTION

One drop of Carebond is placed on brush and then applied thinly and evenly to the base, sides and edges of the freshly conditioned cavity and if the pins are in position they should also be painted.

Ensure all aspects of the cavity and margins are wet with Carebond. Wait for 20 second and with dry air blowing spread Carebond gently

This will also remove solvents.

Light cure 10 sec.

Apply similarly a second coat of care bond; however as soon as it is applied fill cavity with the composite in layer of 3mm and light cure it.

Use transparent matrix:

In box cavities especially the transparent matrix should be used, as this will enable light curing. The base of the cavity should be carefully adapted to the tooth and interdental wedges should be used.

Fill the cavity with the composite such as Hi-Crysta and light cure when complete or follow prescribed procedure.

SECONDARY USE:

Repair of Filling and Restorations

Roughen surface of filling preferably sand blast, wash dry and apply Carebond as directed and light cure.

Treating hypersensitivity

Clean and polish neck of tooth using oil free polishing paste. Wash it and thoroughly dry it. Apply Carebond and follow procedure for light curing. Remove oxygen layer with cotton wool pellet.

Use as Varnish for Glass Ionomers

Paint directly on surface of restoration and disperse with air and light cure for 10 sec (LED >500mW/cm2)

Luting of Root Posts

Following acid etching a drying of prepared root canal Carebond should be applied to root and post. Light cure for 30 sec. separately. Place composite base luting into root canal and seat post firmly into place. Light cure neck of post.

CURE OF LC COMPOSITES (light source: LED >500mW/cm2)

Each surface of restoration should be exposed for at least 10 seconds and additional curing should be carried out buccal and lingual walls. Where pins are in position, it is useful to cure the material around them first and then re-pack the rest. Use cellophane strip, celluloid crowns and celluloid cervical matrix, to hold the restoration and cure through these.

CAUTION:

Carebond contain acetone, which is highly flammable. Keep away from flames. Other contents are acrylates and Methacrylate monomers which can give rise to following fumes. Keep in good ventilated area and don’t breathe in vapours.

May cause whitening of mucosa  due to coagulation of protein. It is reversible and subsides.

Avoid eye contact.  Rinse immediately with plenty of water and seek medical advice.

SPECIAL NOTE:

Replace cap immediately after removal of composite,

Do not expose to the bright light.

Use non-metallic instruments.

STORAGE: Store in cool dry place 4-23’C

Always replace caps after use.

Always keep under dry conditions and away from direct sunlight.
