Using Pure Office whitening gel

Remove the syringe from the fridge and allow it to reach room temperature.

Protect the tooth to be whitened by preparing an operating field.

Assess the quality of the root canal obturation to avoid any risk of the product spreading.

Clean the pulp chamber: remove pulp tissue and necrotic tissue residue.

The canal must have root canal obturation material removed to around 3 mm under the amelocemental junction. Isolate the gutta-percha obturation by placing a small glass ionomer plug.

Place the mixing tip on the Pure Office syringe.

Distribute the product in the prepared canal and compress the product into the cavity using a microapplicator.

Complete temporary closure using a watertight material.

Perform a check 7 days after the procedure.

Repeat application of the product if required.

When the whitening is appropriate, rinse, dry and apply a temporary obturation for 5 weeks before the final reconstruction.
