“…The power density was 35.4 mW/cm 2 . For accuracy in determining the points, we used the ear locator for auriculopuncture (Acupoint detector MH-II ® , Japan), which is based on the principles of electrical potential least resistance, allowing greater accuracy [ 30 ] ( Fig 3 ). A single operator performed the LLL treatment and placebo.…”

ObjectiveEvaluate the effectiveness of LLL (Low level laser therapy) in auriculotherapy points for pain reduction following lower third molar extractions.Study designRandomized, controlled, single-blinded study.MethodsEighty-four bilateral, symmetrical third molar surgeries were performed in 42 healthy patients using a split-mouth design. In the immediate postoperative period, each side was randomly treated in a single-blind method with an LLL at the auriculotherapy points or simulation of its use (contralateral side) over a 21-day interval. This protocol was repeated 24 and 48 hours after surgery. All patients used the same analgesic (paracetamol) but only in case of pain. The primary variable was postoperative pain according to the visual analogue scale, and the secondary variables were mouth opening, edema, local temperature, dysphagia, and the presence of infection (systemic temperature, lymphadenopathy). These variables were evaluated at baseline and at 24 hours, 48 hours and seven days after surgery. Adverse effects were recorded and reported.ResultsThere was no difference between the groups in relation to any of the evaluated parameters (p>0.05).ConclusionFor this experimental model, application of a low-intensity laser at auriculotherapy points did not prevent postoperative pain following lower third molar surgery.Trial registrationThis trial is registered at ClinicalTrials.gov; the registration number is NCT02657174 and the Unique Protocol ID number is 1.100.869.

“…AESR at specific ear auricle region has been an effective diagnostic tool for various diseases, [ 34–38 ] and AESR distribution has been shown in this work to correlate to different body physiological conditions. Hence, AESR signals show great potential in serving as a new diagnostic indicator to supplement conventional diagnostic methods, especially for complicated diseases when conventional physiological signal measurement cannot provide definitive prognostics.…”

“…Thus, only temporal signal recording in specific region can be acquired and spatial‐level characterization is missing. For instance, auricular electrical skin resistance (AESR) signal has been used for diagnosing various human diseases, such as hepatic disorders, [ 34 ] hip injury, [ 35 ] breast cancer, [ 36 ] type‐2 diabetes mellitus, [ 37 ] and metabolic syndrome, [ 38 ] and the pencil‐like commercial auricular detecting tools, which are primarily single‐probe electrical detectors with a rigid metal probe (such as Pointer Excel II, Lhasa OMS Inc., Weymouth, MA, USA), can measure point‐by‐point cutaneous conductance levels by manually moving the probe over the auricular skin surface. But the acquired signal is extremely sensitive to applied pressure, leading to low measurement repeatability.…”

Underneath the ear skin there are rich vascular network and sensory nerve branches. Hence, the 3D mapping of auricular electrophysiological signals can provide new biomedical perspectives. However, it is still extremely challenging for current sensing techniques to cover the entire ultra‐curved auricle. Here, a 3D graphene‐based ear‐conformable sensing device with embedded and distributed 3D electrodes for full‐auricle physiological monitoring is reported. As a proof‐of‐concept, spatiotemporal auricular electrical skin resistance (AESR) mapping is demonstrated for the first time, and human subject‐specific AESR distributions are observed. From the data of more than 30 ears (both right and left ears), the auricular region‐specific AESR changes after cycling exercise are observed in 98% of the tests and are clustered into four groups via machine learning‐based data analyses. Correlations of AESR with heart rate and blood pressure are also studied. This 3D electronic platform and AESR‐based biometrical findings show promising biomedical applications.

Background: A comfortable postoperative return to daily activities has increased the need to control inflammation after third molar surgery. Anti-inflammatory drugs and analgesics are not exempt from adverse effects such as allergies and chronic gastritis, and they are not without cost. The association between low-level laser and auricular acupuncture can be an alternative when conventional drugs are contraindicated. Among its advantages, we can mention the low risk of side effects, low cost and simplicity of application. The objective of this study is to evaluate the efficiency of low-level laser at auriculotherapy points in reducing postoperative pain in lower third molar surgery.
