- Degree of satisfaction using a questionnarie [ Time Frame: 1-2 weeks ]Participant satisfaction will be assessed by asking the question "How satisfied are you with the device?" using a 0-10 point scale (considering 0= extremely dissatisfied and 10 = completely satisfied)
- Degree of improvement or worsening of oral self-biting injuries using a questionnarie [ Time Frame: 1-2 weeks ]The degree of improvement or worsening of oral self-biting injuries while using the device will be assessed by asking the question "How much do you think wearing the device improves the oral self-biting injuries?" using a 0-10 point scale (considering 0= extreme worsening to 10= completely improved).
- Degree of change in their quality of life using a questionnaire [ Time Frame: 1-2 weeks ]The degree of change in their quality of life while using the device because of changes in their oral self-biting injuries will be assessed by asking the question "How much do you think wearing the device improves your quality of life?" using a 4-point scale (considering 0 = nothing, 1 = a bit, 2 = quite, 4 = a lot).
- Compliance [ Time Frame: 1-2 weeks ]Participants compliance using the device will be assessed as the percentage of time the device was used with respect to the recommended time.
- Adverse effects [ Time Frame: 1-2 weeks ]The adverse effects related to use of the device will be recorded (excessive salivation, dry mouth, tooth pain, mucosal irritation, temporomandibular joint (TMJ) pain, TMJ sounds, bite change, other).
- Willingness to pay [ Time Frame: 1-2 weeks ]Participants willingness to pay will be assessed by asking the question "What is the maximum you would pay for the device?"
