Response: Anatomic characteristics of ultrasound imaging of the temporomandibular joint at rest and in various jaw positions: a descriptive study- has changed to "Anatomic characteristics of ultrasound imaging of the temporomandibular joint at rest and in various jaw positions in a healthy individual: a descriptive study"

2. The study was approved by the University Internal Review Board for research with human subjects (IRB #: 22-018).----Please mention the year if approval since the data collection took place on 2022 and early 2023.

Response: The study was approved in the fall of 2022 by the University Internal Review Board for research with human subjects (IRB #: 22-018). Participants were recruited through recruitment flyers, emails, and word of mouth. Recruitment was delayed due to the Covid-19 pandemic. Data collection took place in a controlled laboratory setting at a mid-size university in Illinois in 2022 and early 2023. All participants provided informed consent.

3. Discussion

In this cross-sectional examination of 11 healthy individuals, all 11 participants had some atypical anatomy (flat mandibular head, altered articular disc shape, displacement or deformation of the disc during movement) in US imagining, at least one position (at rest or during jaw movements). However, no participants had current pain/dysfunction and none met the DC-TMD classifications for the condition. Most participants denied symptoms during testing, although one participant did have pain with retrusion and another had popping without pain.-------Please bring it to the result section.

Response: Done

4. Limitations in this investigation include a small sample size, difficulty keeping one US imaging setting to achieve good views of anatomy in each position tested, and lack of standardized measurements of anatomy seen via US imaging for the TMJ. Generalizability is quite limited due to the nature of the research design and noted limitations. An additional limitation and in general for US imaging studies, is the movement of the transducer while a body part is moving and trying to capture an image. This can lead to difficulty in the quality of the images and this study was no exception in that challenge.

Response: Done (a image has changed to an image).
