The device description and performance studies focus on the material properties and biocompatibility of a light-cured dental liner, with no mention of AI or ML.
Yes.
The device is described as a "dentin liner and base" applied to a prepared cavity prior to the insertion of restorative materials, which directly functions to support and protect the dental structure. This falls under the definition of a therapeutic device as it treats or manages a condition (a prepared cavity) to restore or improve health (preparing for restoration of the tooth).
No
This device, Cavios® Cavity Liner, is a dental material used to line a prepared cavity before placing restorative materials. Its function is to act as a physical barrier or base, not to diagnose a condition or disease.
No
The device is a physical material (paste) preloaded into syringes and applied manually, requiring light curing. It is not software.
Based on the provided information, the Cavios® Cavity Liner is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use is to be applied to the interior of a prepared cavity prior to inserting restorative materials. This is a direct application within the body (the tooth cavity), not a test performed in vitro (outside the body) on a sample.
- Device Description: The description details a material applied and cured within the tooth, again indicating in-body use.
- Anatomical Site: The anatomical site is the "Interior of a prepared cavity (dental)," which is part of the human body.
- Performance Studies: The performance studies focus on biocompatibility and material properties (depth of cure, strength, water sorption, solubility), which are relevant to a material placed within the body, not to the diagnostic performance of a test on a sample.
- Predicate Device: The predicate device is a "Calcium Hydroxide Dentin Liner and Protective Base," which is also a material applied within the tooth.
IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening. The Cavios® Cavity Liner is a material used in the body for a therapeutic or restorative purpose, not for diagnostic testing of a sample.

Cavios® is packaged as a multiple use syringe, with new tips being attached for each patient. The syringe can be used until empty. The syringe is kept capped between uses and is fitted with a new tip just prior to use. The syringe is cleaned with an alcohol wipe before and after use.
Indication for Use:
Cavios® Cavity Liner is to be applied to the interior of a prepared cavity prior to the insertion of restorative materials. Cavity Liner is indicated for use in the general dental population.
Intended Use:
Cavios® Cavity Liner is a yellow-white, single-component, light cured, material for dentin liner and base. Cavios® is easily expressed through the plunger type syringe with single use disposable tips. Cavios is intended for the general dental patient population and can be delivered directly into the prepared cavity. The syringe application directly into the cavity. The Cavios material provides excellent radiopacity.
The Intended Use information from the predicate product is equivalent and is reproduced below:
Ultradent Products, Inc's "UltraBlend Plus" calcium hydroxide dentin liner and protective base" is indicated as a cavity liner and/or base material before placing either composite or amalgam. It is also used for pulp capping and small direct exposures without hyperemic bleeding. UltraBlend Plus may also be used as an opaque when amalgam has "tattooed" dentin and an esthetic restoration is being placed or when performing a crown repair where the metal is showing.
As is documented in the comparison of Indications For Use, the Cavios® and Ultra-Blend Plus dentin liner and base are indicated for the same use, share the same clinical indication, clinical setting, target population, anatomical sites, intended use, prescription requirement, storage conditions and method of application.

A technical comparison of the subject device to the predicate device is detailed in the Substantial Equivalence discussion below. Cavios was designed, tested and compared to Ultra-Blend plus (see the comparison table below).
Both Cavios and Ultra-Blend utilize a single-component material that is photo-polymerized to form a liner for subsequent placing of dental restorations. The primary difference between the subject device and the predicate is a minor difference in the filler material. Both products utilize urethane dimethacrylate as the photo-polymerizing base. Cavios employs a-Tricalcium phosphate whereby Ultra-Blend plus uses calcium hydroxyapetite as fillers. Both materials are mixed to maintain the properties of the paste and filling material. Both products utilize barium sulfate to provide radio opacity.
The Cavios® Cavity Liner has been evaluated according to the recognized consensus standards and other testing (see sections 15 and 18) and was found to conform to all requirements. Test data is further discussed in the respective sections (biocompatibility and bench testing)
Non clinical test data:
A number of testing standards were utilized to evaluate Cavios (see Sections 15 and 18). Per ISO 10993-1, Annex A, Cavios can be categorized as follows:

sulfate, ingredients of Cavios, have been widely used in filling materials as filler or radiopaque materials and are free of harmful substances.
ISO 10993-1 presents a schema for deciding whether biocompatibility evaluation is required.
Is there either direct or indirect contact? YES
Is the material the same as in a commercially available device? YES
YES Does the device have the same chemical composition as these devices?
Are the manufacturing and sterilization processes the same? YES
Is the contact to the body the same? YES
Given this schema, there is no need to select biological tests. Nonetheless, we have obtained selected ISO 10993 test results for the Cavios product as follows.

We did not conduct testing for system toxicity, subchronic toxicity, irritation and implantation. The results above in addition to the long and widespread use of these compounds, suggests that there are no biocompatibility issues. A total of 93,000 Cavios units have shipped since 2004; there have been no incidents or adverse reports since 2005. Cavios also carries a CE Mark and was recently re-evaluated in October of 2010.
