It is indicated for cases of root perforation (canal and furcation), iatrogenic or by caries, root perforation by internal resorption, retrofilling, direct pulp capping, pulpotomy, apexigenesis, and apexification. The plasticizer Polyviny|pyrrolidone is added in the subject device to improve the plasticity of the mixture powder/liquid, with plasticity being understood as the quality of being easily shaped or molded. Thus, the new formulation of the subject device improves handling and insertion into the dental cavity since the pasted after mixing becomes a molding putty type consistency. The radiopacifier CaWO4 is also added in the subject device to prevent discoloration of the tooth, since CaWO4 does not reduce when exposed to sunlight, unlike Bi2O3 found in the predicate device. Overall properties noted for the subject device include the following: - . Setting time: MTA Repair HP solidifies upon being maintained in a wet environment after spatulation. The start setting time is approximately 15 minutes. - . Radiopacity: Similar to gutta-percha and more radiopaque than dentin and bone. - . Absence of dental discoloring due to the radiopacifier CaWO4 used. {5}------------------------------------------------ ## Device Comparison Table | Element | Proposed Device<br>(K151047) | Predicate Device<br>(K112046) | |------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | Trade Name | MTA REPAIR HP | MTA ANGELUS | | Device Description | MTA REPAIR HP is an endodontic<br>bioceramic reparative cement with high<br>plasticity, composed of mineral oxides<br>in the form of fine hydrophilic particles.<br>It is indicated for cases of root<br>perforation (canal and furcation),<br>iatrogenic or by caries, root perforation<br>by internal resorption, retrofilling,<br>direct pulp capping, pulpotomy,<br>apexigenesis, and apexification. | MTA Angelus is mineral<br>trioxide aggregate cement<br>used for root repair during<br>endodontic treatment,<br>combining the powder and<br>liquid produces a colloidal gel<br>that solidifies to form a<br>barrier. | | Common Name | Resin, Root Canal Filling | Resin, Root Canal Filling | | Classification | Root Canal Filling Resin | Root Canal Filling Resin | | Class | Class II | Class II | | Product Code | KIF | KIF | | Indications for<br>Use | * Treatment of perforations<br>of root canal and furcation<br>caused iatrogenically or<br>by caries lesions;<br><br>* Via canal treatment of root<br>perforation due to internal<br>resorption;<br><br>* Surgical treatment of root<br>perforation due to internal<br>resorption; | * Treatment of perforations<br>of root canal and furcation<br>caused iatrogenically or by<br>caries lesions<br><br>* Via canal treatment of<br>root perforation due to<br>internal resorption<br><br>* Surgical treatment of<br>root perforation due to<br>internal resorption | | | | | | | * Periapical surgery with | * Periapical surgery | | | reverse filling; | with reverse filling | | | * Pulp capping; | * Pulp capping | | | * Pulpotomy (removal of | * Pulpotomy (removal of | | | affected crown portion of the | affected coronal pulp to | | | pulp preserving the vitality and | preserve vitality of remaining | | | function of the remaining | pulp tissue) | | | radicular portion) | | | | * Apexogenesis (induction of | * Apexogenesis | | | root development in vital teeth | (indication of root | | | with an inflamed coronal pulp) | development in vital teeth | | | | with an inflamed coronal pulp) | | | * Apexification (induction of | * Apexification (induction | | | formation of a mineralized | of formation of a | | | barrier at the root tip of young | mineralized barrier | | | permanent teeth with | at the root tip of | | | incomplete root | young permanent | | | development | teeth with incomplete | | | and a necrotic pulp) | root development | | | | and a necrotic pulp) | | | | | | Biocompatibility | Biocompatible (Biological | Biocompatible | | | Evaluation Report) | | | Design | Powder (capsule) | Powder (bottle) | | | Liquid (capsule) | Liquid (flask) | | Shelf Life | 3 years | 3 years | | | | | | Standards | ISO 6876:2012 | ISO 6876:2012 | | | ANS/ADA Nº 57 - 2000 | ISO 10993-1:2009 | | | ISO 10993-1:2009 | | | Composition:<br>powder | Tricalcium silicate<br>3CaO.SiO2 Dicalcium<br>silicate 2CaO.SiO2;<br>Tricalcium aluminate<br>3CaO.

MTA HP meets the applicable requirements of the following FDA recognized standards: - ISO 10993-1 Biological evaluation of medical devices-part 1: evaluation and testing. - ISO 10993.5: 2009 Biological evaluation for medical devices Tests for cytotoxicity: in vitro methods - ISO 10993-6: 2007 Biological evaluation of medical devices part 6: Tests for local effects after implantation and protocol supplied by the vendor. - ISO 10993-11: 2006 Biological evaluation of medical devices part 11: Tests for systemic toxicity, described in method TOX-052 Rev. 01. - . ANSI/ADA Specification no. 57: Endodontic Sealing Material, 2000. - . ISO 6876:2012 - Dentistry -- Root Canal Sealing Materials Flow, working time and film thickness ISO 6876 testing is not applicable to root-end filling materials as expected. This is because MTA Repair HP is a root repair material, not a root canal sealer. In this particular situation, ISO 6876:2012 - "Dentistry – Root canal sealing materials" is used as guide to determine properties such as setting time, radiopacity, and solubility. These test results are consistent with the {8}------------------------------------------------ intended use of root repair materials, because if the material is too fluid there is no possibility to seal the lateral of a root perforation without experiencing the flowing of the cement and, consequently the loss of the material. Bench test results allowed us to conclude that MTA Repair HP is well suited for its intended use. #### Substantial Equivalence: The subject and the predicate device are substantially equivalent based on identical indications for use, same operating principle and similar material and design. MTA HP and MTA Angelus present the same components except for their radiopacifier. This new radiopacifier agent prevents the discoloration of the tooth, since CaWO4 in the subject device does not reduce when exposed to sunlight, as does Bi2O3 in the predicate device. MTA HP comes also with a plasticizer in its liquid to improve the plasticity of the material. Physical chemistry and biocompatibility properties of the subject device have not been affected. However, both the substitution of the radiopacifier agent and the addition of the plasticizer into the liquid did not affect the critical properties (setting time, solubility and radiopacity) of MTA REPAIR HP. There is a one minute difference noted in the working time of the subject device, compared to its predicate; however, the time difference does not affect the usability of the subject device. #### Conclusion: The subject device and the predicate devices have intended use, have similar technological characteristics, and are made of similar materials. The subject device and predicate device encompass the same range of physical dimensions, including setting time, solubility, biocompatibility and shelf life. The subject and predicate devices are packaged in similar materials and both are provided nonsterile. Any differences in the technological characteristics do not raise new concerns. Angelus Industria De Productos Odontologicos has demonstrated that, for the purposes of FDA's regulation of medical devices, MTA Repair HP is substantially equivalent in indications and design principles to its predicate device MTA-Angelus.
