A. On
Newly Placed Composites:
1. Light cure and contour the composite.
2. Apply acid etchant,
such as UNI-ETCH®* w/ BAC, to the cured composite
and adjacent tooth structure for 15 seconds.
3. Rinse and dry.
4. Continue with
Section "Applying BisCover LV".
B. On
Old/Previously-Placed Composites or for Reapplication:
1. Pumice the surface, or sandblast, or roughen with
a fine diamond. Rinse and dry.
2. Apply acid etchant,
such as UNI-ETCH w/ BAC, to the cured composite and adjacent
tooth structure for 15 seconds.
3. Rinse and dry.
4. Continue with Section "Applying BisCover
LV".
C. Provisionals
(all types):
NOTE: Can be used prior to or after cementation.
1. Contour the provisional
restoration.
2. Rinse and dry.
(Etching is not required.)
3. Continue with
Section "Applying BisCover LV".
D. On
a Light-Cured/Dual-Cured Resin-Modified Glass Ionomer:
1. Place Resin-Modified Glass Ionomer per manufacturer's
instructions.
2. Light cure for
3-5 seconds at 500mW/cm2 and contour.
3. Continue with
Section "Applying BisCover LV".
E. In
Orthodontic Applications:
Prior to Bracket
Placement:
1. Clean the surface with a slurry of pumice/water.
2. Etch the entire
area with phosphoric acid, such as UNI-ETCH w/ BAC, for 30
seconds (120 seconds for primary teeth).
3. Rinse with water
(approx. 10-20 seconds) and dry thoroughly. The etched
area will appear frosty white. If not, re-etch for an
additional 20 seconds.
4. Continue with
Section "Applying BisCover LV".
5. Apply bracket
cement, according to manufacturer's instructions.
If Brackets Have
Already Been Placed:
1. Follow same instructions as in section E,
"Prior to Bracket Placement" excluding step
5.
F. Enamel
[after Whitening (Bleaching)]:
1. Clean the surface with a slurry of pumice/water.
2. Etch the surface
with 32% phosphoric acid, such as UNI-ETCH w/ BAC, for 30 seconds.
3. Rinse with water
(approx. 10-20 seconds) and dry thoroughly. The etched
area will appear frosty white. If not, re-etch for an
additional 20 seconds.
4. Continue with
Section "Applying BisCover LV".
G. Acrylic
Appliances:
1. Contour the appliance.
Clean the appliance thoroughly.
2. Rinse and dry.
3. Continue with
Section "Applying BisCover LV".
H. On Indirect
Composites:
NOTE: Can be used prior to or after cementation.
1. Pumice the surface, or sandblast, or roughen
with a fine diamond. Rinse and dry.
2. Apply acid etchant, such as UNI-ETCH w/ BAC, to the cured
composite and adjacent tooth structure for 15 seconds.
3. Rinse and dry.
4. Continue with Section "Applying BisCover
LV".
1.
If using a bottle of BisCover LV, dispense BisCover LV into a mixing well. Dip the brush into the BisCover LV. Wipe excess from the brush onto the side of mixing well. The brush does not need to be saturated, just wet enough to apply one thin coat. If using the BisCover LV syringe, apply directly using a syringe and an applicator tip. (NOTE: This is a low viscosity material and as such, care must be taken to control the amount of material dispensed from the syringe. It is also recommended that the tip be removed from the syringe and the cap replaced immediately upon completion of application.)
2. Apply one thin coat of BisCover LV in one
direction with a smooth stroke. Do not agitate the brush
during application. It is very important that one
allows 15 seconds dwelling time for evaporation
of solvent after application. Do not air thin as
this will disperse the material unevenly causing ripples
on the surface.
CAUTION: Upon curing, BisCover LV may
produce a brief exothermic reaction which is minimized
by applying in a thin layer. Do not cure on soft tissue.
3. BisCover LV uses the following curing lights
and curing times to initiate polymerization. Insufficient
curing will leave an air-inhibited layer on the surface
of BisCover LV.
a. LED Lights: Using an LED curing light with
a minimum output of 500mW/cm², light cure for 30
seconds at close range (0-2mm).
b. Halogen Lights: Using a halogen curing unit,
such as VIP™* junior, with a
minimum output of 500mW/cm², light cure for 30
seconds at close range (0-2mm).
NOTE: If the light intensity is lower and/or
curing occurs at a distance (10mm), light cure for greater
than 30 seconds.
c. PAC (Plasma Arc) Lights: Using a PAC light,
light cure for 10 seconds at close range (0-2mm).
4. If a second coat is desired, repeat steps 1-3.
Troubleshooting:
OBSERVATION: After curing, the treated
surface has white spots.
1. Insufficient evaporation of the solvent has occurred
due to too thick of a layer or entrapment of solvent.
SOLUTION: Remove BisCover LV with
rotary instruments and apply again, allowing sufficient
time for evaporation of the solvent.
OBSERVATION: The surface is tacky after
curing.
1. The light intensity may be less than the required
amount. The lamp may be old and need replacement, or
the internal filter may be scratched and dirty.
SOLUTION: Use a radiometer to determine
the actual output intensity, and/or increase the curing time.
2. The light guide may be too far away from the surface.
Light divergence reduces the intensity at the curing
surface as the light spreads to cover a larger area.
SOLUTION: Keep probe 1-2mm from surface,
and/or increase the curing time.
3. Residue build-up on the tip of the probe may block
light and reduce the intensity. A chipped or scratched
probe tip will also contribute to reduced intensity.
SOLUTION: Clean the tip of the light probe,
and/or increase the curing time.
4. Substrate was contaminated.
SOLUTION: Apply a second coat of BisCover
LV.
OBSERVATION: The surface is not tacky
but it can be scratched.
1. BisCover LV requires a minimum curing intensity
regardless of the amount of time cured. Holding the
light at a distance will reduce the intensity dramatically
due to light divergence.
SOLUTION: When curing a large surface
area, it is better to cure smaller sections at close
range as opposed to the whole area from a distance.
OBSERVATION: The surface is not cured
uniformly.
1. The intensity of the curing light may not be uniformly
distributed as an output, falling off in intensity towards
the outer periphery. This is further exaggerated as
the distance between the probe and surface are increased.
SOLUTION: When curing a large surface
area, it is better to cure smaller sections at close
range as opposed to the whole area from a distance.
STORAGE: Store at room temperature (22°C/72°F).
Refer to individual component labels for specific expiration
dates.
PRECAUTIONS: Unpolymerized resins may cause skin
sensitization in susceptible persons. In case of contact
with the skin, wash thoroughly with soap and water.
Do not cure on soft tissue.
