Intended Use

Proseal Enamel Coating Resin is a light curing material for sealing the enamel pits and fissures of teeth.

Device Story

Proseal Enamel Coating Resin is a light-curing dental sealant composed of methacrylate resin, photo initiator system, and inorganic fillers. It is supplied in syringes or bottles for professional use by dental clinicians. The material is applied to the enamel pits and fissures of teeth; it features a color-change technology, appearing pink upon application to aid in placement accuracy and transitioning to an opaque off-white color upon light-curing. This process provides a physical barrier to prevent dental caries. The device is used in a clinical dental setting to improve oral health outcomes by protecting susceptible tooth surfaces.

Clinical Evidence

No clinical data. Substantial equivalence is supported by in-vitro bench testing, including depth of cure, flexural strength, shear bonding strength, compressive strength, water sorption, solubility, film thickness, and elastic modulus, all meeting ISO 6874:2015 criteria. Biocompatibility testing (cytotoxicity, sensitization, irritation, systemic toxicity, subchronic toxicity, genotoxicity) was performed per ISO 10993.

Technological Characteristics

Flowable paste composed of methacrylate resin, photo initiator, and inorganic fillers. Light-cured. Complies with ISO 6874:2015 (Class 2 sealant), ISO 7405, and ISO 10993-1. Delivered via syringe or bottle.

Indications for Use

Indicated for sealing enamel pits and fissures of teeth in patients requiring dental sealant treatment.

Regulatory Classification

Identification

A pit and fissure sealant and conditioner is a device composed of resin, such as polymethylmethacrylate, intended for use primarily in young children to seal pit and fissure depressions (faults in the enamel) in the biting surfaces of teeth to prevent cavities.

Dear Maggie Zheng:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.
