Calplus is a temporary or permanent root canal filling material for use following pulpectomy, or for apexogenesis or apexification.

Cerafill RCS is a MTA (mineral trioxide aggregate) based root canal sealer that provides complete and permanent sealing of root canals. It can be used with or without root canal obturation materials.

Endoseal is used for permanent obturation of the root canal space with the aid of obturating points in accordance with ISO 6876 for Dental Root Canal Sealing materials.

Nanoseal S is indicated in patients for permanent obturations of root canal after vital extirpation or after treatment of pulpal gangrene and temporary filling.

Zical Ultra Paste is used for permanent obturation of the root canal space with the aid of obturating points.

Zical Ultra Powder/Liquid is used for permanent obturation of the root canal space with the aid of obturating points.

Device Description

CalApex is a non-eugenol, radiopaque, calcium hydroxide polymeric resin root canal filling material. It is a two part, base/catalyst – paste/paste system that is mixed in equal portions. The mixture is then carried to the root canal with endodontic obturation points or directly dispensed in the root canal depending on delivery method, e.g. tube or dual-barrel syringe.

Calplus can be used as a temporary or permanent root canal filling material.

Cerafill RCS is an endodontic sealer based on MTA, providing a biocompatible and effective root canal filling. It is premixed and pre-loaded in a syringe, which allows a complete filling of the entire root canal including accessory and lateral canals. The product is eugenol-free and will not impede adhesion inside the root canal.

Endoseal is a Zinc Oxide/Eugenol root canal sealant. The product is made up of two separate components, a powder base and a liquid catalyst, to form the final device.

Nanoseal S is a permanent root canal filling material which is silicone based (polydimethylsiloxane). It is cold flowable and is in a dual barrel cartridge.

Zical Ultra Paste is a two-part, base/accelerator, paste/paste system that is mixed in equal portions. The mixture is carried to the root canal with endodontic obturation points. The product comes in a dual barrel cartridge.

Zical Ultra Powder/Liquid is a two-part, powder/liquid system for permanent filling of root canals. The mixture is carried to the root canal with endodontic obturation points.

Indications for Use:

Testing Summary:

CalApex, Cerafill RCS, Endoseal, Nanoseal S, Zical Ultra Paste, and Zical Ultra (powder/liquid) were tested for appearance, flow, film thickness, water solubility, working time, and disintegration according to protocols based on ISO 6876:2012 and tested for radio-opacity according to a protocol based on ISO 13116:2014. CalPlus was tested for appearance, flow and film thickness according to ISO 6876:2012, and radio-opacity according to ISO 13116: 2014.

{5}------------------------------------------------

Appearance uses a pass/fail criteria set for each device based on the acceptable appearance of each paste, base or catalyst.

Flow test method is based on Section 5.2 of ISO 6876:2012. The CalApex, Cerafill RCS, Endoseal, Nanoseal S, Zical Ultra Paste, and Zical Ultra (powder/liquid) pass criteria is not less than 17mm. The CalPlus pass criteria is 25-28mm.

Film thickness is based on Section 5.5 of ISO 6876:2012. The pass criteria for all subject root canal sealers is not more than 50µm.

Water solubility is based on Section 5.6 of ISO 6876:2012. The pass criteria for all subject root canal sealers is shall not be more than 3% by mass.

Working time is based on Section 5.3 of ISO 6876:2012. The CalAPex pass criteria is 16-18min. The Cerafill RCS, Endoseal, Zical Ultra Paste, and Zical Ultra (powder/liquid) pass criteria is 25-30min. The Nanoseal S pass criteria is 8-10min.

Setting time is based on Section 5.4 of ISO 6876:2012. The CalApex pass criteria is 20-40min. The Cerafill RCS pass criteria is 24 hours. The Endoseal, Zical Ultra Paste, and Zical Ultra (powder/liquid) pass criteria is 45-60min. The Nanoseal S pass criteria is 10-15min.

Disintegration is based on Section 4.3.5 of ISO 6876:2012. The pass criteria for all subject root canal sealers is no evidence of disintegration.

Radio-opacity is based on ISO 13116:2014. The pass criteria for all subject root canal sealers is above or equal to 3 mm when compared with aluminum wedge.

All test results passed and the test method pass criteria in standards. All test reports are included. The bench testing is the same type of test done by the predicate and reference devices. The pass criteria are either the same as the predicate and reference devices (in some cases ISO 6876 sets pass criteria for all root canal sealers) or the pass criteria are tighter than those of the predicate and reference devices. Having a tighter pass criteria would not change the substantial equivalence because the subject devices would also still meet the pass criteria used by the predicate and reference devices.

Shelf life for the root canal sealers is 3 years except for CalApex which is 2 years. Shelf life uses the same testing protocols as the characterization testing which are based on ISO 6876:2012. Pass criteria are the same as for bench testing. The predicate and reference devices use the same ISO standard for their testing but have unknown shelf lives in most cases (Sealapex and MTA Fillapex have a 2 year shelf life).

A biocompatibility assessment according to ISO 10993 was provided for all subject devices.

Conclusion: Prevest Denpro Root Canal Sealers are substantially equivalent to the predicate device, Sealapex. They have the same indications, similar testing, and very similar ingredients. The subject devices and predicate or reference devices have similar forms, work, and setting times, flow, film thickness, water solubility, radiopacity. The pass criteria are either the same as the predicate and reference devices (in some cases ISO 6872 sets pass criteria for all root canal sealers) or the pass criteria are tighter than those of the predicate and reference devices. Having a tighter pass criteria would not change the substantial equivalence because the subject devices would also still meet the pass criteria used by the predicate and reference devices.

Any differences in the measured parameters are minor and do not change the substantial equivalence because all the values meet ISO 6876 or other relevant standard. Both the subject devices and the predicate device have physical parameters which meet requirements of the relevant ISO standards. Both the subject devices and predicate/reference devices have biocompatibility assessments according to ISO 10993. Shelf life testing is similar to the shelf life testing of predicate or reference device. Reference devices are included to cover any ingredients, or indications not covered by the predicate devices. Any differences in ingredients are minor and do not change the substantial equivalence.
