Obturation
After the preparation and chemical cleaning of the root canal system, the canals have to be tightly sealed with a suitable obturation to prevent reinfection. Komet provides a comprehensive range of paper and gutta-percha points as well as F360 Fill, a carrier-based filling system. Komet BioSeal is a bioceramic sealer and EasySeal is a sealer based on epoxy resin. Root canal sealers are mainly used to fill voids, seal additional root canals and multiple foramina. What’s more, endodontic sealers are intended for creating a bond between the filling material and the canal wall and for encasing residual bacteria in the canal.

Komet BioSeal
Komet BioSeal is a new endodontic bioceramic obturation material which perfectly meets all the demands placed on a modern root canal filling material.
Advantages
Bactericidal effect:
Komet BioSeal has the ability to effectively eliminate existing bacteria in the root canal. Komet BioSeal owes its excellent antibacterial effect to the initially high pH value during curing.
Excellent biocompatibility:
Thanks to its calcium-silicate based material, Komet BioSeal has an excellent biocompatibility after having set and, therefore, prevents foreign body reactions by the surrounding tissue. This, in turn, promotes quick healing and reduces post-operative pain.
Easy application and short curing time:
Komet BioSeal has hydrophilic properties and is ready for use. Unlike conventional sealers based on epoxy resin, Komet BioSeal uses the residual moisture from the dentinal tubules for curing. Thanks to the short curing time, combined with the easy and safe application, predictable and reliable obturation results can be achieved using cold filling techniques (for example single-cone technique).
Optimum sealing ability and perfect adhesive bond:
Highly flowable, Komet BioSeal has an optimum sealing ability and creates a perfect adhesive bond between the dentin and gutta-percha. In combination, these two properties prevent the reinfection of the root canal after obturation.
Highly radiopaque:
The specific composition of bioceramic sealers is a real challenge in terms of radiopacity. Thanks to its optimized material composition with zirconium oxide particles, Komet BioSeal is distinguished by an excellent radiopacity.
Step by Step.
After the final rinse, the canal system is dried with paper points of congruent shape and the gutta-percha is adapted.
The root canal system is filled with KometBioSeal through the fine tip of an application syringe.
The guttapercha point is inserted with pumping movements and shortened to the correct working length, for example with the EndoPilot Downpack handpiece

Why bioceramic?
Root canal sealers mainly serve to seal voids, additional root canals and multiple foramina. What’s more, endodontic sealers are intended for creating a bond between the filling material and the canal wall and for sealing off residual bacteria in the canal.
Bioceramic materials have been used in numerous other medical disciplines for many years, for example in orthopaedics. Thanks to KometBioSeal, these materials can now also be used in endodontics.
Advantages
Bactericidal effect:
KometBioSeal owes its excellent antibacterial effect [ 2 ] to its initially high pH value during the curing phase. This means that any bacteria that may be present in the root canal are eliminated. Thanks to its consistently high pH value that remains stable for several days, the disinfecting effect of KometBioSeal is similar to that of a calcium hydroxide insert.
Excellent biocompatibility:
KometBioSeal is based on calcium-silicate, which is why it is particularly biocompatible after the curing phase. In addition, it emits calcium ions [1]. These properties prevent foreign body reactions and, in turn, accelerate the healing process. In addition, cells that have settled on the sealer exhibit a positive proliferation.
Perfect adhesion and easy application:
The adhesion values of KometBioSeal are similar to those of epoxy resin sealers, which facilitates a perfect adhesive bond between the dentin, KometBioSeal and the gutta-percha. Moreover, KometBioSeal has hydrophilic properties, which means that, contrary to conventional sealers based on epoxy resin, KometBioSeal uses the residual moisture in the dentinal tubules for curing. This means that, unlike epoxy resin sealers, KometBioSeal achieves its excellent adhesion values not only under ideal conditions, but also under clinical condition.
On the one hand, this makes the material both easy and safe to use, so that in combination with cold filling techniques, such as for example the single cone technique, a safe and reliable result can be achieved. On the other hand, the adhesive bond and the dimensional stability prevent an undesirable reinfection of the root canal.
(see scanning electron micrograph [ 3 ]).
High radiopacity:
The specific composition of bioceramic sealers presents a major challenge in terms of radiopacity. KometBioSeal owes its outstanding radiopacity [ 4 ] to its optimized formulation containing zirconium oxide particles. The radiopacity of KometBioSeal is similar to that of epoxy based sealers and clearly superior to other bioceramic sealers, giving the user perfect control of the treatment result.
EasySeal
After a successful treatment of the root canal, the root filling is responsible for tightly sealing the canal to prevent reinfection
The high standard among sealers.
Permanent seal:
EasySeal is a root filling material on the basis of epoxy resin. The special composition of the matrial allows excellent adhesion to the dentin. A permanent seal can be guaranteed thanks to the low solubility and great resistance to high temperatures. With EasySeal, the root canal is duably protected from renewed bacterial attack.
Reduced risk of reinfection:
EasySeal is particularly flowable. Like this, even tiny dentinal tubules can be filled with EasySeal, safely preventing reinfections.
Fast and comfortable use:
The Easyseal root filling material comes in a twin-chamber syringe which allows safe and easy application without previous mixing. What´s more, te short setting time of 15 minutes allows a spreedy treatment.
Step by Step.
Clinical sequence:
1. Clean the root canal thoroughly and dry with paper points and an oil-free air jet fr approx. 10 seconds.
2. Before use, remove the cap of the double-chamber syringe by turning anti- clockwise. Check the level of the two components in the double-chamber syringe (see Fig. A-C). Attach a mixing cannula/ mixing tip (and Endo tip) and tighten by turning in a clockwise direction. Press both pastes into the mixing cannula by pressing the piston.
3. Squeeze Easyseal onto a mixing block, pick up and insert into the canal with a lentulo spiral.
Alternatively, select a suitable Masterpoint, cut apically, apply EasySeal and insert into the canal. The mixed root filling paste is workable for approx. 15 minutes.
4. Fill the root canal by means of condensation or thermoplastic techniques using gutta-percha. Full setting is reached at 37°C body temperature within 24hours
5. After use, remove the mixing cannula and close EasySeal with the sealng cap.

Root filling material on the basis of epoxy resin
A permanent apical seal of the root canal can be achieved with EasySeal, a root filling material based on epoxy resin. EasySeal is particularly suitable for orthograde filling techniques, it is radiopaque and dimensionally stable. EasySeal comes in a double-chamber syringe for easy, safe handling without need for previous mixing. The workable time of EasySeal is 15 minutes. Full setting is reached at 37°C body temperature within 24 hours.
Root filling materials based on epoxy resin, such as EasySeal, are classed as high standard thanks to their outstanding properties, for example excellent adhesion to dentin, low solubility and high thermo stability.
Leakage test with dye.
Root filling materials based on epoxy resin, such as EasySeal, are classed as high standard thanks to their outstanding properties, for example excellent adhesion to dentin, low solubility and high thermo stability.
EasySeal: The filling is tight, preventing bacteria from entering. The dye could not penetrate between the gutta-percha and the canal wall.
Commercially available sealer: The dye was allowed to penetrate right up to the guttapercha. The filling is not tight. No protection from renewed bacterial attacks.
