To promote good oral hygiene, including plaque removal and treating and preventing gingivitis.
Oral-B® Sonic Complete™ is a rechargeable electric toothbrush comprised of a charging unit and a rechargeable power handle. The rechargeable power unit is inductively charged and therefore electrically safe in accordance with the Second Edition of the standard for Personal Hygiene and Health Care appliances, UL 1431. The Oral-B® Sonic Complete™ electric toothbrush has a vibrating brush head that moves with a side-to-side movement. The brush head is designed to facilitate deeper penetration of interdental areas. The brush head moves side along the axis of the brush head at 260 Hz at an unloaded angle of ± 5 degrees. The brush head has no moving parts and is similar to a manual brush. The Oral-B® Sonic Complete™ has a longitudinal brush head with a length of 22 mm and a width of a 9mm. The tufts are angled in 3 directions. The inner row with oval tufts and the outer rows are angled in opposite directions at an angle of 7.5 degrees. In addition, the outer rows are angled outwards for improved gumline cleaning at an angle of 5 degrees. The bristles are standard nylon filaments with a diameter of 6 and 6.5 mil. Two rows of bristles are longer and form a power tip for improved interproximal cleaning. These power tips have a wear indicator function and are colored with the FDA approved colorant FD&C blue No.2. The bristle material is Polyamid or PA6.12. The Oral-B® Sonic Complete™ features a Pressure Control to help avoid possible gingival damage by users who apply excessive pressure during brushing; the drive system and the soft bristles are designed so that the bristle tip movement dramatically decreases to almost zero at applied loads above 2 N. It also features a Professional Timer and a Push-Push switch. The Professional Timer automatically interrupts the brushing motion briefly with a short stuttering sound every 30 seconds to remind the user to move to another quadrant of the mouth, so that each quadrant is brushed equally. At the moment we only have a "stuttering timer" as described, however there soon will be a version sounding a "beeping noise" after 2 minutes brushing time, Oral-B® Sonic Complete™ offers customized brushing modes for complete mouth care. The basic godel offers two modes and the deluxe model offers three modes controlled by the Push switch: Clears for a complete cleaning of your teeth and gums, Soft: for the gentle care of your tongue and other sensitive areas, and Massage: (deluxe model only) for a gentle stimulation of gums. The toothbrush features a round handle, with anti-slip characteristics for better control in wet conditions.
The provided text describes the Oral-B® Sonic Complete™ rechargeable electric toothbrush. While it states that the device has been tested in numerous controlled clinical studies and that these trials evaluated oral soft and hard tissue for safety, plaque, gingivitis, and bleeding, it does not explicitly detail specific quantitative acceptance criteria or the full study methodology in the typical format for medical device performance studies. The document focuses on demonstrating substantial equivalence for an expanded indication for use (treating and preventing gingivitis) rather than presenting a detailed performance study with predefined acceptance criteria for the device itself.
However, based on the information provided, we can infer some aspects related to the testing and "acceptance" of the device in the context of its 510(k) submission.
Here's an attempt to structure the information based on the typical requirements, acknowledging the limitations of the provided text:
Acceptance Criteria and Device Performance
The document does not provide a table with quantitative acceptance criteria for device performance. Instead, the acceptance is based on demonstrating the device's safety and effectiveness for its intended use, particularly the expanded indication of "treating and preventing gingivitis," and its substantial equivalence to predicate devices. The "reported device performance" is descriptive rather than quantitative in the provided text excerpts.

Study Details
The document states that "Oral-B® Sonic Complete™ powered toothbrush has been tested in numerous controlled clinical studies. These trials evaluated oral soft and hard tissue for safety, plaque, gingivitis and bleeding. Collectively, these studies demonstrate that the Oral-B® Sonic Complete™ powered toothbrush is effective at treating and preventing gingivitis." However, it does not provide all the granular details requested for a single, comprehensive study. It references two clinical studies in the bibliography.
-
Sample size used for the test set and the data provenance:
- Test set sample size: Not explicitly stated in the summary.
- Data provenance:
- Study 1 reference (Cronin et al., 2004): Conducted by "New Institutional Service Co., Inc., Dental Research and Product Testing, Northfield, New Jersey, USA." This suggests the data is prospective and from the USA.
- Study 2 reference (Rosema et al., 2004): Department of Periodontology, Academic Centre for Dentistry Amsterdam. This suggests the data is prospective and from Amsterdam (Netherlands).
-
Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not explicitly stated in the provided text. Clinical studies of this nature would typically involve trained dental professionals (e.g., periodontists, dental hygienists) for assessments.
-
Adjudication method for the test set: Not explicitly stated. For clinical studies evaluating gingivitis and plaque, assessments are typically performed by trained examiners following standardized protocols, and reliability checks (e.g., inter-rater agreement) are common, but specific adjudication methods like "2+1" are not mentioned.
-
If a multi-reader multi-case (MRMC) comparative effectiveness study was done:
- The provided text refers to "controlled clinical studies" demonstrating effectiveness, but it does not describe an MRMC study comparing human readers with and without AI assistance. This type of study (MRMC for AI) is typically for diagnostic imaging devices, not direct-to-consumer toothbrushes.
- The studies mentioned compare the device itself (with its cleaning mechanism) against either a control or another toothbrush, not human readers and AI.
-
If a standalone (i.e. algorithm only without human-in-the loop performance) was done: No, this device is a physical toothbrush, not an algorithm. Therefore, "standalone" algorithm performance is not applicable. The device's performance is inherently "human-in-the-loop" as a user operates it.
-
The type of ground truth used:
- Clinical Endpoints: Based on the description ("evaluated oral soft and hard tissue for safety, plaque, gingivitis and bleeding"), the ground truth would be based on clinical assessments/measurements (e.g., Gingival Index, Plaque Index, Bleeding on Probing) performed by trained dental professionals.
- Bibliography references studies that focus on "efficacy of two toothbrushes" (Study 1) and "Healing Effect of Experimental Gingivitis Using 2 Sonic Toothbrushes" (Study 2), further indicating clinical measures as ground truth.
-
The sample size for the training set: Not applicable in the context of this device and the provided documentation. This information is relevant for AI/machine learning models which are not described here. The "training set" for a physical device would refer to data used during its development and optimization, which is not detailed in a 510(k) summary for a toothbrush.
-
How the ground truth for the training set was established: Not applicable, as explained above.
