AquaCem – glass ionomer luting cement

AquaCem
AquaCem is a light yellow, translucent glass ionomer luting material consisting of a blend of alumino-silicate glass and polyacrylic acid.

The powder is mixed with distilled water to produce a luting material which adheres to dentin and enamel producing tightly sealed cementations. Delivery forms: а powder/liquid version for hand mixing.

Indications for use: cementation of crowns, inlays, bridges, and orthodontic bands.

Contraindications: direct or indirect application to dental pulp (direct or indirect pulp-capping). Cementation of extensive bridgework when the time needed for application of the cement and positioning of the bridge exceeds the working time (2 minutes 30 seconds) of AquaCem.

Composition

  • Calcium-sodium-fluoro-phosphoroaluminium-silicate
  • Polyacrylic acid
  • Tartaric acid
  • Iron oxide pigments

Safety notes
Be aware of the following general safety notes and the special safety notes in other chapters of these Instructions for Use.

Warnings
Components and mixed material AquaCem may be irritating to skin, eyes and oral mucosa.

  • Avoid eye contact to prevent irritation and possible corneal damage. In case of contact with eyes rinse with plenty of water and seek medical attention.
  • Avoid skin contact to prevent irritation. In case of contact, reddish rashes may be seen on the skin. If contact with skin occurs, remove material with cotton and alcohol and wash thoroughly with soap and water. In case of skin sensitization or rash,
    discontinue use and seek medical attention.
  • Avoid contact with oral soft tissues/mucosa to prevent inflammation. If accidental contact occurs, remove material from the tissues. Flush mucosa with plenty of water and expectorate/evacuate the water. If inflammation of mucosa persists, seek
    medical attention.

Precautions

AquaCem is intended to be used only as specifically outlined in these Instructions for Use. Any use of this product inconsistent with these Instructions for Use is at the discretion and sole responsibility of the dental practitioner.

  • Use protective measures for the dental team and patients such as glasses and rubber dam in accordance with local best practice.
  • Contact with saliva, blood and sulcus fluid during application may cause failure of the restoration. Use adequate isolation such as rubber dam.
  • To prevent bottles, powder scoop and mixing pad from exposure to spatter or spray of body fluids or contaminated hands it is recommended that the bottles, powder scoop and mixing pad are handled offside the dental unit with clean/disinfected
    gloves.
  • Tightly close bottle immediately after use.
  • The desiccant crystals integrated in the cap and/or drying capsule protect the powder from absorbing moisture. The color of the desiccant crystals should be orange. The desiccant crystals are no longer effective after the color has turned from orange to colorless.
  • Increased temperature and/or humidity reduce available working time and accelerate setting time. Material will set faster in the mouth than at the bench. Do not use bench cure rates to judge mouth cure rates.
  • The product should be mixed in proportions of one level scoop powder to two drops water 1 for optimum performance. The mixed material should be homogeneous and streak free prior to application. Variations may affect the strength and durability of the material.
  • Use in a well-ventilated area. Avoid inhaling dust particles from powder

Adverse reactions

  • Eye contact: Irritation and possible corneal damage.
  • Skin contact: Irritation. Reddish rashes may be seen on the skin.
  • Contact with mucous membranes: Inflammation (see Warnings).

Storage conditions
Inadequate storage conditions may shorten the shelf life and may lead to malfunction of the product.

  • Store with original (not dropper cap) caps tightly closed in a well-ventilated place at temperatures between 10 °C and 24 °C (50 °F and 75 °F).
  • Allow material to reach room temperature prior to use.
  • Protect from moisture.
  • Do not use after expiration date.

AquaCem – step-by-step instructions

Cavity preparation

  1. Isolate the field of operation in preferred manner. Rubber dam is recommended.
  2. Cavity preparation must provide for the mechanical retention of the product.
  3. If caries is present, completely excavate using low-speed and/or hand instrumentation.
  4. Place matrix and wedge where indicated.
  5. Gently dry preparation with cotton pellet. Avoid desiccation.

Pulp protection

  1. In deep cavities cover the dentin close to the pulp (less than 1 mm) with a hardsetting calcium hydroxide liner (Dycal calcium hydroxide liner, see complete Instructions for Use).

Dosage and mixing

  1. Invert powder bottle to fluff the powder.
  2. Overfill the scoop with powder and strike off the excess with the bottle insert leaving a flat surface level with the edge of the scoop.

NOTICE
Premature setting of material
Reduced working time AquaCem.

  1. Keep powder and liquid separated until ready for mixing.
  2. Place the powder onto the pad provided or on a glass slab. Special spatulas are not required.
  3. Divide the powder into two halves.
  4. Fill water dispenser with distilled or de-ionized water.
  5. Dispense two drops of water by holding the bottle vertically and squeezing gently.
  6. Add one half of the powder to the water. As soon as the first half is wetted, incorporate the second, then mix thoroughly. The measures are intended as a guide; the mix should have a smooth creamy consistency. It is essential that the powder is incorporated very quickly into the water to ensure the optimum mix ratio. For all normal uses the mixing time should not exceed 15 seconds.

Working and setting time

  • From start of mixing, the remaining working time is approximately 2 minutes 30 seconds.
  • After mixing, the setting time is 3 minutes 30 seconds to 5 minutes.

Application

  1. Apply cement onto the fitting surface of the restoration/orthodontic band and/or the prepared tooth immediately upon completion of the mix whilst appearance is glossy.
  2. Position the restoration/orthodontic band and apply adequate pressure to seat it. Avoid contamination with water/saliva during application and setting. It should, however, be noted that the cement remains subject to dehydration if left isolated for longer than 10 minutes from start of mixing. This means that water balance must be maintained by releasing the cement to the oral environment within this time range.

Finishing

  1. Excess material may be removed at once or after completion of setting time (see 3.4 Working and setting time). Do not touch the cement when it is in the intermediate, rubbery condition. For removal of surplus material, appropriate hand instruments, like a dental probe, and dental floss are used.

Cleaning instruments
Glass ionomers adhere to instruments and glass slabs.

  1. Immediately after use, either clean instruments with water or drop in disinfectant or water to facilitate subsequent cleaning.
