Bioseal is a biocompatible, radiopaque, hydroxylapatite-filled zinc oxide and eugenol root canal cement. It represents an evolution over conventional zinc oxide and eugenol cements because it is characterized by greater biocompatibility and does not contain any strong antiseptics.

The recent confirmation of these possibilities has eliminated the need to incorporate tissue-fixing antiseptics (such as formaldehyde or derivatives) into root canal cements. These agents, in addition to transforming vital and necrotic microresidues into a dangerously antigenic material, also risk involving the remaining vital tissues of the delta and periodontium, which are crucial for repair, in their fixative action. Bioseal's unique formulation therefore reflects the current trend toward achieving a seal of the endodontium within the anatomical limits of the canal that is as inert and biocompatible as possible.

In fact, root canal filling is not currently understood as an operative phase which aims to resolve problems that are related to root canal preparation and treatments, but as a completion of the previous emptying phase which must however be carried out with the adoption of operative techniques which do not create iatrogenic damage, with suitable instruments, with appropriate irrigating solutions (see Niclor-5, Tubuliclean) and with “Biophilic” treatments of any micro-residues (Endoidrox).

Directions:
Root canal fillings with cement only or mixed cement-gutta-percha.
How to use:
Mix the contents of a capsule with a drop of liquid; mix thoroughly until the product has a creamy, thick, and uniform consistency. Add more liquid if desired.
- Normal (orange-white capsule) shows the first signs of hardening on the plate after 10-15 minutes.
- Retard (yellow-white capsule) after 30-40 minutes.
Final curing is approximately 90 and 300 minutes respectively.
The working time can be significantly extended by trowelling the concrete onto a slab.
Naturally, inside the root canal, increased temperature and humidity contribute to faster hardening of the material. The operator can therefore choose the version with the features best suited to the filling technique used and their working time.

In vital teeth: complete the preparation with at least one hydroxide treatment before definitively closing the canal. This facilitates solubilization and the subsequent removal, through abundant irrigation (Niclor 5 and sterile saline solution), of any lacerated or bruised pulp fragments remaining in the canal following the ectomy procedures, which become necrotic.

In necrotic teeth: it is recommended to remove the hydroxide treatment at least three times, one week apart, in order to benefit as much as possible from the alkalizing and solubilizing action of calcium hydroxide (Endoidrox).
