Intended Use

Sealapex/Sealapex Xpress is a calcium hydroxide, polymeric resin, root canal filling material that is used in conjunction with gutta percha or silver endodontic points.

Device Story

Sealapex/Sealapex Xpress is a non-eugenol, radiopaque, calcium hydroxide polymeric resin root canal sealer. It functions as a two-part base/catalyst paste system that hardens upon mixing in the presence of root canal moisture. The device is used by licensed dental professionals during endodontic procedures to fill microscopic gaps between the obturator and canal walls. It is delivered either via hand-mixed tubes or a dual-barrel syringe with single-use automix tips. The sealer acts as a barrier against blood, exudates, and infection, facilitating successful root canal obturation.

Clinical Evidence

Bench testing only. Performance evaluated per ISO 6876:2012 for consistency (flow), film thickness, and radiopacity. Results showed flow of 23.1 mm (vs 22.8 mm predicate), film thickness of 33.85 µm (vs 20.3 µm predicate), and radiopacity of 6.0 mm Al (vs >3.3 mm Al predicate). All results met ISO specifications.

Technological Characteristics

### 3. Predicate Device:

The proposed Sealapex Sealapex Xpress is substantially equivalent to the legally marketed device, Sealapex 4 (K010940), cleared on June 20, 2001, product code KIF.

### 4. Description of Device:

Sealapex/Sealapex Xpress is a non-eugenol, radiopaque, calcium hydroxide polymeric resin root canal filling material. It is indicated for use as a root canal sealing and filling material, and is used during an endodontic procedure to seal off the prepared root canal apical foramen and tubules from blood, exudates, and infection. The proposed is a twopart, base/catalyst - paste/paste system that is mixed in equal portions. Then, the mixture is 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.

The proposed is available packaged in tubes (Sealapex) and dual-barrel syringes (Sealapex Xpress) used with single-use automix tips. The tubes are dispensed onto a mixing pad, hand mixed and then applied to the canal with an endodontic point. Sealapex Xpress has the same formulation and indications for use as Sealapex, but is branded as "Sealapex Xpress" since it offers the convenience of single-use automix tips that remove

{4}------------------------------------------------

the need for hand mixing. The dual-barrel and single-use automix tips allow the dental professional to deliver the desired volume of Sealapex Xpress directly into the prepped root canal.

# 5. Statement of Indications for Use:

Sealapex/Sealapex Xpress is a calcium hydroxide, polymeric resin, root canal filling material that is used in conjunction with gutta percha or silver endodontic points.

- 6. Technological Characteristics:
Sealapex/Sealapex Xpress is intended to fill the microscopic gaps between the canal filler/obturator and canal walls. Reactive components that let Sealapex Xpress sealer set in root-canal are Calcium Oxide in base paste and Salicylate moieties in accelerator (catalyst) paste. Material hardens upon mixing of the base and accelerator pastes in the presence of moisture in the root canal.

The paste base formulation of the proposed Sealapex Xpress and the predicate device, Sealapex 4 (K010940), is very similar, the only difference being an increase in the amount of Resin and Titanium Dioxide, along with a slight addition of a Silica in the proposed Sealapex/Sealapex Xpress base formulation.

The paste catalyst formulation of the proposed Sealapex Xpress and the predicate device, Sealapex 4 (K010940), is very similar, the only difference being a decrease in amount of filler, a decrease in Titanium Dioxide, along with the slight addition of a Silica in the proposed Sealapex/Sealapex Xpress catalyst formulation. Titanium Dioxide (USP) is a common non-toxic white pigment approved by FDA as a food additive, and the minor change does not affect performance or biocompatibility of the paste.

Fumed silica filler serves as a rheological modifier. It does not participate in the setting reaction. Both fillers in the proposed base and catalyst formulations are similar in physical characteristics and surface treated to make the filler particle more hydrophobic and to improve the compatibility with the formulation.

The Resin is an inert, water-insoluble material that helps thicken the paste and does not participate in setting reaction. The slight increase in the amount of Resin should stabilize the consistency of the paste and does not adversely affect the equivalence and performance of the product.

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

The slightly modified formulation for the proposed Sealapex Xpress has successfully been on the EU market for several years. Performance testing on stability, work time, set time and slump were performed on the modified formula to validate that the proposed products meet the current product specifications and are substantially equivalent to the predicate Sealapex 4 (K010940).

- 7. Non-Clinical Performance Data:
Verification activities were performed in accordance with design control requirements as specified in 21 CFR 820.30 and ISO 13485 Medical Devices- Quality Management Systems and the results demonstrated substantial equivalence to the predicate.

- 8. Summary of Performance Testing Performance Testing Bench
Performance testing for the proposed Sealapex/ Sealapex Xpress included testing for Consistency (Flow), Film Thickness, and Radiopacity per ISO 6876:2012 - Dentistry -Root Canal Sealing Materials.

In the Physical and Mechanical Properties of Table 6.2, the film thickness has a 13.5 micron (um) difference between the predicate and proposed devices. This difference does not affect the substantial equivalence of the subject and predicate devices. The sealer was tested to meet ISO 6876:2012 standard, which states that a sealer shall have a film thickness of not more than 50 um. The proposed Sealapex and Sealapex Xpress are below the maximum 50 um allowance. Therefore, the predicate and proposed sealers will flow sufficiently into the root canal and adapt to canal shape to fill voids.

Table 6.2 displays both an internal and the ISO 6876:2012 test method for determining Flow. The internal test method for Flow differs from the current ISO 6876:2012 test procedure due to the amount of sample used for testing.

The predicate and proposed devices produced Flow results of 48.5 mm and 51.0 mm, respectively, based on internal test methods. This data shows no substantial difference between the predicate and proposed devices. Per ISO 6876:2012, the predicate and proposed devices show no substantial difference based on Flow test results of 22.8 mm and 23.1 mm, respectively.

The data analyzed from the various tests substantiate that the proposed Sealapex/ Sealapex Xpress is substantially equivalent to the predicate Sealapex 4 (K010940).

- 9. Substantial Equivalence:
Sealapex 4 (K010940) is an existing device which was granted market clearance by FDA in 2001. Sybron Dental Specialties, on behalf of SybronEndo, seeks only to slightly modify the formula of the existing device cleared under K010940. Additionally, the device would be produced at a sister facility in Scafati, Italy; and the manufacturer name will change to SybronEndo.

Table 6.2 depicts the comparison of performance and mechanical properties and modification associated with the proposed Sealapex Xpress.

# 10. Conclusion as to Substantial Equivalence:

The slight modifications of Sealapex Xpress base and catalyst formulations and the move of the manufacturing location to Scafati, Italy does not affect the intended use of the device nor does it alter the fundamental scientific technology of the device. The nonclinical testing demonstrates that the proposed Sealapex Xpress performs as well as the predicate device based on the specifications set by ISO 6876:2012 testing requirements. The proposed Sealapex/Sealapex Xpress are substantially equivalent to the predicate Sealapex 4 (K010940).
