Intended Use

Dexis Webview is a web-based software used for general dental and maxillofacial diagnostic image review that allows users alternate access to image data using a common web-browser. It provides the ability to view, enhance, annotate, compare, and export images by accessing an existing image database available in a distributed environment.

Device Story

Dexis Webview is a web-browser-based software application providing remote access to preexisting dental and maxillofacial imaging data stored in a Dexis Core database. Operated by dentists or dental technicians in clinical environments, it allows users to view, enhance, annotate, compare, and export images (X-rays, intraoral/extraoral camera images, digitized film) via standard web browsers on desktop PCs or Macs. The device functions as a remote viewer; it does not perform image acquisition. By enabling remote diagnostic review of images, it assists practitioners in clinical decision-making and enhances diagnostic value through image processing tools.

Clinical Evidence

No clinical data. Safety and effectiveness were established via bench testing, verification, and validation testing, and conformance to ISO 14971 (risk management).

Technological Characteristics

Software-only application; web-browser interface; compatible with Windows and Mac OS. Functions as a remote viewer for dental X-rays and color images. Connectivity via distributed network to Dexis Core database. Complies with ISO 14971.

Indications for Use

Indicated for use by prescription by a trained and qualified dentist or dental technician for general dental and maxillofacial diagnostic image review.

The Dexis Webview software uses common web browsers (Internet Explorer, Chrome, etc) with regards to viewing, enhancing, annotating, comparing, and exporting images using the Dexis Core database in an alternate fashion similar to the access provided by the Dexis software and aiding in the practitioner's decision making process. The following is the functionality comparison:

The Dexis Webview Software is a software program for general dental and maxillofacial diagnostic imaging. It provides the ability to view, enhance, annotate, compare, and export images by accessing an existing image database available in a distributed environment. It allows remote access to x-ray digital images acquired from digital imaging systems. It can also handle other types of images acquired by digitizing film with a flatbed scanner, or color images from intraoral dental cameras as long as they are stored in an accessible database.

{6}------------------------------------------------

Dexis Webview allows the following functionality remotely using a standard web-browser:

- . Access and analyze x-ray images acquired from imaging plates with the Photo-Stimulable Phosphor (PSP) scanners.
- . Access and analyze x-ray images acquired using from intra-oral and extra-oral sensors.
- . Access patient files remotely via a standard web-browser with established network connectivity.
- . Access and view color images from intra-oral and extra-oral cameras,
- . Access, export, and import digital images (such as those obtained by scanning a film) in several standard file formats.
- . Process images with dental specific tools, to enhance their diagnostic value.
- Analyze and enhance images in order to gather additional diagnostic information which may not be immediately apparent on initial visual inspection.
- . Print images and image-related information over the network.

Dexis Webview is typically utilized remotely using a web-browser over a networked environment.

# Substantial Equivalence

The Dexis Webview web-browser Software with the updated Indications for Use and intended use described in this submission is substantially equivalent to the Dexis Software cleared under K140445. It also satisfies all criteria of substantial equivalence based upon the above comparisons in the sections and does not raise new concerns in safety and effectiveness: (1) Indications for Use, (2) Technological Characteristics, and (3) Theory of Operations. The new device does not introduce a fundamentally new scientific technology and the nonclinical tests demonstrate that the device is safe and effective. Thus, the Dexis Webview (proposed under K151941) is substantially equivalent to the cleared Dexis Software (K140445).

# Performance Data

Whereas Dexis Software can capture digital images from various sensors (e.g. intraoral), Dexis Webview can only view, enhance, annotate, compare, and export already acquired images by remotely accessing such images over the network. The proposed device has the same fundamental scientific technology, has not been reclassified, and has an intended use which correlates with that of the predicate device. The safety and effectiveness of the Dexis Webview web-browser software was evaluated via bench testing. verification and validation testing, and conformance to international conformance standards. The Dexis Webview Software performs equivalently in functionality as the cleared Dexis Software (K140445) with regards to viewing, enhancing, annotating, comparing, and exporting images by remotely accessing an existing image database available in a distributed environment. Dexis Webview complies with the following relevant standard: ISO 14971 Second edition 2007-03-01. medical devices - application of risk management to medical devices. Performance data (Verification and Validation) demonstrate that Dexis Webview web-browser software functions equivalently to the Dexis Software predicate device.
