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

5. How to use ACTIVA clinically : steps ?
Step 1
![](https://images.storychief.com/account_1794/Screenshot2020-10-07at9_28_06AM_15ce95cdd9623a5b2e13ada47d5f6f5e_800.png)
- Remove infected dentin.
- Apply pulp protection, if indicated.
- The enamel margins should be bevelled and rounded for a better marginal seal.
Step 2
![](https://images.storychief.com/account_1794/Screenshot2020-10-07at9_28_18AM_9aa0d24ac6eaf980826972cb0004c5ea_800.png)
- 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
![](https://images.storychief.com/account_1794/Screenshot2020-10-07at9_31_32AM_e8544ff93c1019d6daf7b2d45343991e_800.png)
- Apply bonding agent.
- This eliminates variables related to cavity preparation, retention form, sensitivity, and wet vs. dry surfaces.
Step 4
![](https://images.storychief.com/account_1794/Screenshot2020-10-07at9_31_42AM_d203667cf2f11e42a832414e973e7414_800.png)
- Place the dispenser needle mix tip against the floor of the cavity.
- Flow ACTIVA ahead of tip.
Step 5
![](https://images.storychief.com/account_1794/Screenshot2020-10-07at9_33_15AM_6e2ef2092fe9861e6d4e6be7df79af89_800.png)
- 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
![](https://images.storychief.com/account_1794/Screenshot2020-10-07at9_34_40AM_1b4ea53c15206b47d5a3681133d5047a_800.png)
- 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
![](https://images.storychief.com/account_1794/Screenshot2020-10-07at9_34_55AM_48c1b63609ddd3dd826ba99a57fc6d93_800.png)
- 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.
