Carefil-PL 30g Powder 10ml Liquid | Microfine Glass Ionomer for Permanent Restorative | Dental Filling Material

COMPLIES WITH: B.S.6039:1981 TYPE 2 I.S.O. 7489: 1986 TYPE 2

This is a snap-setting special powder/liquid glass ionomer filling material. Available in twelve shades, Carefil-PL’s fraction matches that of tooth structure, preventing the shin-through or matt white effect resulting from the use of other opaque, glass ionomer liners with composites.

INDICATIONS: Restoration of cervical erosion areas, root caries and restoring deciduous cavities. Restoring class III and V cavities (alone or with a composite overlay) fissure filling. It can also used as a liner in conjunction with composite restorative materials, i.e. the ‘Sandwich’ technique for anterior restorations.

PRESENTATIONS: Available in all Vita Shades.

MIXIMG METHOD

Mixing Ratio: 1 Scoop Powder: 1 Drop of Liquid

                       Optimum Ratio at 23°C & 50% RH

                       2.5-2.63 Powder: 1g Liquid

MIXING DIRECTIONS:

Before each use, fluff powder by inverting bottle several times. Using the scoop, place a level scoop of powder onto the mixing pad. Repeat as required.

Divide into 3 equal portions on mixing pad.

To ensure uniform drops of liquid, hold the dispensing bottle in a vertical position, squeeze gently and release after each drop separates. Dispense required number of liquid drops onto mixing pad. Wipe with a damp napkin to prevent clogging of nozzle.

Using a plastic spatula, incorporate one of the three portions of powder into the liquid. Mix in successive portions until the material reaches a homogenous composite like consistency. Mixing should be completed in 30 seconds.

Follow appropriate application techniques.

Coat restoration with two layers of varnish.

TECHNIQUE INSTRUCTIONS WHEN USED ALONE:

Excavate decay and/or prepare and clean stained area to be restored with pumice or all free paste (oil contain formulation or Prophy Paste will interfere with bonding). Mechanical retention should be provided by dovetailing or other means.

NOTE: Rubber dam or retractor should be used to prevent moisture contamination.

Place Calcium hydroxide over all pulped or near pulped exposure areas only.

Apply a glass ionomer conditioner or other Polyacrylic acid containing liquid with cotton pledged fro 10 seconds.

If present, acid etch enamel area for one minute, rinse and dry (optional).

Mix Carefil-PL according to instructions.

Place and contour as required over the previously prepared decayed or eroded areas. This procedure is similar to the use of composites and silicates. Where a stainless steel matrix band is used this should be very lightly coated with Vaseline; plastic strips can also be used. The initial setting time for Carefil-PL is 4 minutes 30 seconds.

Immediately cover the restoration with varnish.

Wait 10 minutes from the time of placement before finishing and polishing with fine diamond or other rotary type instrument.

Apply another layer of varnish.

EROSIONS, ABRASIONS, LESIONS.

All stains are removed by polishing with Prophy Paste and if caries are present they should be excavated and lined.  The conditioner is applied via cotton pledged for 30 seconds. The cavity is then washed and dried ready to receive restoration.

FISSURE FILLING:

The fissures are opened to a depth of 2mm, remove caries etc., wash and dry and then carry out fissure filling as normal using the mix recommended. Finishing and polishing can be accomplished after 7 minutes. Mixing on a cold glass slab will prolong working and setting times.

CATIONS:

Liquid is adhesive and contains Polyacrylic acid. Spatula and instrument should be wiped clean before setting.

Wash spillages immediately.

In case of contact with skin/eyes, wash immediately with plenty of water and seek medical advice if necessary.

Powder is very fine, may give rise to dust, however it is recommended that the lid should be replaced immediately after use or between uses.

STORAGE: Store at normal room temperature in sealed form.
