1. ACTIVA and bonding agents

a) Which bonding agent should I use with ACTIVA?

Whichever you are comfortable with.

b) How can ACTIVA BioACTIVE bring about apatite formation through a bonding agent?

Bonding agents are permeable and allow the exchange and diffusion of ions.

2. How deep can ACTIVA BioACTIVE cure?

As ACTIVA is a dual cure material, it also will cure chemically, no matter how deep the restoration. If we talk only about the photocuring, ACTIVA has a 4 mm curing depth.

3. Is ACTIVA a bulk fill material?

ACTIVA is indicated for bulk filling, being a dual cure material. But it works great if we choose to use layering technique for our restorations.

4. What are the clinical indications for ACTIVA?

ACTIVA is a very versatile material. It can be used in any of the following situations :

  • Posterior Restorations
  • Anterior Restorations
  • Class l, ll, lll, lV, V

Step 1

  • Remove infected dentin.
  • Apply pulp protection, if indicated.
  • The enamel margins should be bevelled and rounded for a better marginal seal.

Step 2

  • Etch 10-15 seconds
  • Rinse and dry, but do not desiccate the tooth.
  • Total etch dentin & enamel for 10-15 seconds
  • Selective etch enamel for 15 seconds

Step 3

  • Apply bonding agent.
  • This eliminates variables related to cavity preparation, retention form, sensitivity, and wet vs. dry surfaces.

Step 4

  • Place the dispenser needle mix tip against the floor of the cavity.
  • Flow ACTIVA ahead of tip.

Step 5

  • Place a thin insulating layer of ACTIVA, massage into dentin for 20 seconds
  • Light cure before bulk filling.
  • This mitigates polymerization stress and exothermic reaction.

Step 6

  • Keep tip submerged in the material at all times to avoid air bubbles.
  • Maintain contact with the floor.

Step 7

  • Fill up the cavity

Step 8

  • Allow ACTIVA to self-cure at least 20-30 seconds before light curing.
  • Set curing light to the 20-second low-intensity setting to reduce heat and sensitivity.
  • Self-cure setting time is 2-3 minutes.
  • Before removing the matrix bands, light cure the material or allow it to self- cure for 3 minutes. If allowing ACTIVA to self- cure, covering ACTIVA with an oxygen barrier, such as glycerin, will eliminate the O2 layer.

Step 9

  • Adjust occlusion, finish and polish.
