– if the patient is known to be allergic to any of the ingredients in
Tetric EvoFlow.
Side effects
In individual cases, components of Tetric EvoFlow may lead to sensitization.
Tetric EvoFlow should not be used in such cases.
To avoid possible irritation of the pulp, areas close to the pulp should be
protected with a suitable pulp/dentin protector (apply a calcium hydroxide-
based preparation to areas in close proximity to the pulp).
Interactions
Substances containing eugenol/clove oil may inhibit the polymerization of
composite materials. Consequently, application of such materials together
with Tetric EvoFlow must be avoided. Discolouration may occur in combina-
tion with cationic mouthwashes, plaque disclosing agents and chlorhexi-
dine.
Application in restorative therapy
1. Select the shade.
2. Provide appropriate isolation, best with a rubber dam
(e.g. OptraDam ® Plus).
3. Prepare the cavity according to the requirements of the adhesive technique.
4. Clean the cavity with water spray.
5. Air dry the cavity.
6. Do not apply a base material when using an enamel/dentin bonding
agent. Selectively cover very deep areas close to the pulp with a calcium
hydroxide material (e.g. ApexCal
resistant cement (e.g. a glass ionomer cement, such as Vivaglass
Liner). Do not cover other cavity walls, since they can be used to sup-
port the bond with an enamel/dentin adhesive.
7. Apply matrix (e.g. OptraMatrix
8. Condition and apply the bonding agent according to the instructions for
use of the product in use. We recommend using Syntac
phoric acid etching) or ExciTE
AdheSE ® One F self-etching adhesive.
9. Apply Tetric EvoFlow in layers of max. 2 mm or 1.5 mm (Dentin shades,
Bleach XL, IVA5, IVA6). Polymerize each layer according to the table
shown below. Hold the light emission window as closely as possible to
the surface of the restorative material. When using a metal matrix,
additionally polymerize from the buccal or lingual/palatal after remov-
ing the matrix.

11. Finish the restoration with suitable finishers (e.g. Astropol

12. Check the occlusion.
13. Polish with silicone polishers (e.g. Astropol P/HP, Astrobrush
single-step OptraPol
and polishing strips.
Application for the cementation of ceramic or
composite restorations
Tetric EvoFlow is to be used exclusively in light-curing procedures. Conse-
quently, the composite is only suitable for the cementation of restorations
that are sufficiently translucent to permit enough polymerization light to
pass through the restoration and reach Tetric EvoFlow in order that the
composite can cure completely. Before being cemented in place, the restora-
tion has to be pre-treated according to the instructions of the manufacturer.
Prepare the cavity as follows:
1. Appropriate isolation, i.e. with a rubber dam or OptraDam
required.
2. Remove the temporary restoration and any residue of the temporary
luting material and clean the cavity with a prophy paste (e.g. Proxyt);
subsequently, rinse with water spray and dry the cavity.
3. Condition and apply the bonding agent according to the instructions for
®
use of the product in use. If necessary, protect the adjacent tooth with a
matrix band during conditioning.
4. Apply Tetric EvoFlow directly to the restoration; insert the restoration,
and remove excess material. To prevent the formation of an oxygen
inhibited layer, an oxygen-tight glycerine gel (e.g. Liquid Strip) may be
applied along the restoration margins. Make sure that the glycerine gel
is not mixed with Tetric EvoFlow!
5. Next, polymerize Tetric EvoFlow in segments starting with the proximal
margin:
– If a curing unit with a light intensity of min. 800 mW/cm
bluephase), light-cure for 10 s per mm of ceramic and segment.
– If a curing unit with a light intensity of 500 to 800 mW/cm
light-cure for 20 s per mm of ceramic and segment.
Remove the gel with water spray after polymerization.
6. After polymerization, remove excess material with suitable finishers
(e.g. Astropol F or single-step OptraPol Next Generation) or fine dia-
monds. Remove proximal excess with diamond or tungsten carbide
finishers or finishing strips. Check the occlusion and articulation and
adjust if necessary. Use silicone polishers (e.g. Astropol P/HP, OptraPol
5 s
Next Generation) as well as polishing discs and polishing strips to
polish the restoration to a high gloss.
