Evaluation of an Intra Auricular Device as a Treatment for Painful Temporo-Mandibular Disorders (IAD)

May 4, 2022 updated by: Valeria Donnarumma, Federico II University

Prospective Longitudinal Study for the Evaluation of an Intra Auricular Device as a Treatment for Painful Temporo-Mandibular Disorders

Background: An innovative, non-invasive, and reversible Intra Auricular Device (IAD) has recently been introduced to treat temporomandibular muscle and joint disorders.Aim: To evaluate the effects of the IAD on pain, psychosocial domain and Pressure Pain Threshold (PPT) of masticatory muscles in patients with TMD pain. Methods: Ten subjects with TMD pain and with pain intensity higher than 30 mm on a VAS scale were included in the study. Patients received the IAD and counselling. Assessments included questionnaires of the DC/TMD Axis II questionnaires (Characteristic Pain Index, Interference, Jaw Functional Limitation Scale, Patient Health Questionnaire 9, Patient Health Questionnaire 15, Generalized Anxiety Disorder scale, Oral Behavior Checklist and Oral Health Impact Profile-22, Axis I clinical examination and PPTs at baseline (T0), after one month (T1), three months (T2) and six months (T3) from the first use of the device. PPTs were measured at anterior temporalis muscles, masseter muscles and right thenar as a control site.The Shapiro-Wilk test was used for the normal distribution of data. The difference among the longitudinal timepoints for variable was analysed with ANOVA. Statistical significance was accepted at p < 0.05.

  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: TMD Pain group
Arm included patients with TMD Pain intensity >3 on a VAS scale and with diagnosis of myofascial pain, either alone or in combination with arthralgia, headache attributable to TMD or with disc displacement with reduction. Participants had to be 18 years of age or older. All subjects had to wear the device for 6 months and it should not be used for more than 23 hours in a 24-hour period
Device: Intra auricular device (IAD)
The Intra Auricular Device (IADs) are a pair of inconspicuous, custom fit auricular prosthetic devices.The ear inserts are manufactured using computer-aided design/computer-aided manufacturing (CAD/CAM) technology and are made from a liquid, photo-reactive acrylate (EShell 300), used in hearing aid shells and otoplastics for the last 10 years. They are designed to be placed into the outer third of the ear canals, and they have a small retraction post used to facilitate removal . A red or blue dot, respectively, indicates the right and the left side. The device do not interfere with hearing or speech

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change of Pain (evaluated with Characteristic pain intensity scale)
Time Frame: Six months from the first use of the device
This questionnaire is a valid instrument assessing pain intensity, numbers of days with interference and pain-related disability in the last month. The characteristic pain intensity score, which ranges from 0-100, is calculated as the mean intensity ratings for reported current, worst, and average pain
Six months from the first use of the device
Change of Pain evaluated with instrumental exam( Pain Pressure Threshold)
Time Frame: Six months from the first use of the device
Pain Pressure Threshold were assessed by a single examiner at the anterior temporalis and masseter muscles (respectively TdxM; TsxM; MdxM; MsxM). An additional measurement was performed at the right thenar muscle (TenM) selected as a control muscular site.
Six months from the first use of the device
Psychosocial domain positive change
Time Frame: Six months from the first use of the device
Evaluation of psychosocial positive change through psychosocial questionnaires.
Six months from the first use of the device
