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.
