MAQUIRA APPLIC COMPOSITE

Cleaning

Thoroughly clean the tooth surface with a rubber cup and a fluoride-free paste then rinse with water.

Shade Selection

Select the appropriate shade of PALFIQUE LX5 prior to placing the rubber dam using the shade guide provided for PALFIQUE LX5.

1. Complete the shade selection within 5 minutes; desiccated teeth are lighter than wet or moist teeth.
2. Lightness (color value) is primary importance on shade selection.
3. When wavering in shade selection, select the lighter (high value) shade.
4. In case of whitened teeth select the shade a few weeks after the completion of whitening. Whitened teeth may become slight darker.

Isolation

A rubber dam is the preferred method to isolate the tooth from contamination.

Cavity Preparation

Prepare the cavity and rinse with water. Add bevels to the enamel margins of anterior preparations (class III, IV, V), as well as chamfers to the margins of posterior preparations (class I, II) because bevels and chamfers assist in erasing demarcations between the cavity margins and restoration, thereby enhancing both esthetics and retention.

1. Scalloped (undulant) bevel could be desirable depending on the esthetics and retention.
2. In case of porcelain/composite repairs, roughen the surface with a bur or a diamond point to prepare the area for adhesion; apply phosphoric acid etch for cleaning; rinse thoroughly with water; air dry thoroughly and treat with a silane coupling agent according to manufacturers instructions.

Pulp Protection

Glass ionomer lining or calcium hydroxide should be applied if the cavity is in close proximity to the pulp. DO NOT USE EUGENOL BASED MATERIALS to protect the pulp. as these materials will inhibit curing of bonding agent and/or PALFIQUE LX5.

Bonding system

Apply light-cured bonding system according to manufacturers instructions.

1. Do not use self-cured bonding systems. We advise that light-cured bonding systems should be used with PALFIQUE LX5 since other types of bonding systems such as self-cured or dual-cured bonding systems may not provide effective adhesion when used with light-cured composite resins. If you want to use self-cured or dual-cured bonding systems, please confirm that such bonding systems are compatible with the light-cured composite resins being used.

Dispensing

Remove the syringe cap. Extrude the paste onto a mixing pad by turning the handle clockwise. After dispensing, turn the handle counter clockwise by a half to full turn to release residual pressure inside the syringe and re-cap the syringe immediately. DO NOT apply unnecessary force to the syringe immediately after removing from the refrigerator.

Filling and contouring

Fill the cavity incrementally. Increments should not exceed the indicated depth DO NOT mix PALFIQUE LX5 with other brands of resin composite or other shades of PALFIQUE LX5 to avoid incomplete cure or voids.

Curing

Light-cure each increment for at least the indicated keeping the curing light tip within a distance of 2 mm from the increment.If other brands of composite resins are layered over the cured composite, follow their instructions.

Finishing

Shape and polish the restoration. For finishing, use fine finishing diamond points. To erase the demarcation between the composite and the natural tooth rotate a 12 fluted carbide bur slowly along the margins without water. Use finishing metal strips or vinyl strips for proximal surfaces. For polishing, polish with rubber points or any suitable polishing tool.
