PULPDENT OBA-MCP is a light-cure orthodontic adhesive composite for the direct bonding of orthodontic brackets. For dental professional use only.
PULPDENT OBA-MCP is a light-cure orthodontic adhesive composite containing modified calcium phosphate that releases fluoride, calcium, and phosphate ions into the oral environment. OBA-MCP is not formulated with Bisphenol A. BisGMA, or BPA derivatives.
The provided text is a 510(k) summary for the PULPDENT OBA-MCP (Orthodontic Bracket Adhesive with MCP). This document focuses on demonstrating substantial equivalence to a predicate device rather than presenting a performance study with acceptance criteria in the typical sense for an AI/ML medical device.
Therefore, the requested information about acceptance criteria, study details, sample sizes, expert qualifications, adjudication methods, MRMC studies, standalone performance, and ground truth for an AI/ML device is not available in the provided text.
The document primarily addresses:
- Device Description: A light-cure orthodontic adhesive composite containing modified calcium phosphate that releases fluoride, calcium, and phosphate ions.
- Indications for Use: Light cure orthodontic adhesive composite for the direct and indirect bonding of orthodontic brackets. For dental professional use only.
- Predicate Device: PULPDENT OBA - Orthodontic Bracket Adhesive (K911286).
- Reference Device: PULPDENT Solo Flowable Composite with MCP (K153249).
- Biocompatibility Evaluation: Stated that PULPDENT OBA-MCP is substantially equivalent to the predicate (Pulpdent OBA) which has an established history of safe and effective use. It also mentions that the reference device (Pulpdent Solo Flowable Composite with MCP) was tested with a Cytotoxicity Test (ISO 10993-5 2009) and an Implantation Test (ANSI/ADA Specification 41 and ISO 7405) and found to be biocompatible.
- Device Comparison: A table comparing the subject device with the predicate and reference devices on aspects like description, technology/mechanism of action, indications for use, composition, and physical properties (appearance, specific gravity, water absorption, fluoride release, phosphate release, calcium release, compressive strength, flexural strength, diametral tensile strength, light cure set times).
- Discussion of Differences: The key difference is the addition of Modified Calcium Phosphate (MCP) and the removal of BisGMA from the original OBA formulation. The document argues that MCP is biocompatible and that the enamel bond strength of materials with calcium phosphate is comparable to those without it, referencing a study by "Zhang, et.al." (details not provided).
Since this is a submission for an adhesive material, the "performance" discussed is related to its physical and chemical properties and biocompatibility, not diagnostic or predictive accuracy in the context of AI/ML.
To directly answer your request based on the provided text, I must state that the information requested for AI/ML device evaluation is not present.

Similarities
Pulpdent OBA-MCP and the predicate product, OBA, both share the same technology and mechanism of action, as an orthodontic bracket adhesive. They have essentially the same physical properties and nearly identical chemical formulations.
Differences
Pulpdent OBA-MCP differs from Pulpdent OBA with the addition of MCP (Modified Calcium Phosphate). Additionally, the BisGMA has been removed from the original OBA formulation.
Discussion of the Differences
MCP, or Modified Calcium Phosphate, is a methacrylate moiety, with stabilized calcium and phosphate ions, that is used as a filler in dental materials. In the natural course of the tooth, and its demineralization and remineralization processes in acidic oral environments, there is an ongoing exchange of biologically available calcium and phosphate ions. The addition of calcium and phosphate ions to dental products can be seen in many premarket approved devices. Biocompatability testing performed on products with a similar chemcial composition (including the reference device) have confirmed that a calcium and phospahte addition is biocompatible (see file 012 Biocompatabiltiy Evaluation). It has also been shown that the enamel bond strength of orthodontic materials containing a calcium phosphate moiety exhibits a comparable bond strength to commercially available cements without calcium phosphate. (Zhang, et.al., file ecopy)
Conclusion
Taking into account the above similarities and differences, Pulpdent OBA-MCP Orthodontic Bracket Adhesive with MCP, is substantially equivalent, in design, performance and indications for use, to the predicate product, Pulpdent OBA - Orthodontic Bracket Adhesive.
