Electric pulp testing is one of the pulp vitality tests which aid dentists in diagnosis of the pulp status. This test is technique sensitive and hence may elicit false responses. There are some concerns regarding the optimal placement of the probe tip. The threshold value (the lowest electric current at which sensation is perceived) is reached when an adequate number of nerve fibers are stimulated, so the sensation would be greatest where the density of neural distribution is the highest. The purpose of this study was to identify the optimum site for electrode placement in anterior teeth of adults, the threshold values of these teeth using an electric pulp test, and to determine the influence of sex, age, and arch on the outcome. The optimum electrode placement sites and threshold values varied with type of tooth and arch. The maxillary teeth, canines, male gender and increasing age required higher electric current to evoke a sensation, while incisal edges required lower current to evoke a sensation.

Purpose: Precise electrode placement is crucial for the success of sacral neuromodulation (SNM). The aim of this study was to explore a more accurate and convenient method for positioning punctures during the first stage of SNM.
Methods: This retrospective study compared preoperative baseline values, intraoperative indicators, postoperative scores, and other clinical data from 130 patients who underwent SNM electrode implantation at our department between 2018 and 2023.

Objectives: Multiple studies have described the onset and variable incidence of postoperative acute vertigo following cochlear implant (CI) surgery. However, postoperative imaging has not yet been specifically evaluated with special focus on vertigo. The aim of this study is to assess the incidence and causes of new-onset, acute postoperative vertigo following CI surgery using cone beam computed tomography (CBCT).

Background: There is growing interest in use of transcutaneous spinal stimulation (TSS) for people with neurologic conditions both to augment volitional control (by facilitating motoneuron excitability), and to decrease spasticity (by activating inhibitory networks). Various electrode montages are used during TSS, with little understanding of how electrode position influences spinal circuit activation. We sought to identify the thoracolumbar electrode montage associated with the most robust activation of spinal circuits by comparing posterior root-muscle reflexes (PRM reflexes) elicited by 6 montages.

Electroconvulsive therapy (ECT) is an effective treatment for depression but is often associated with cognitive side effects. In patients, ECT-induced electric field (E-field) strength across brain regions varies significantly due to anatomical differences, which may explain individual differences in cognitive side effects. We examined the relationship between regional E-field strength and change in verbal fluency score (i.

Purpose: Cochlear implantation (CI) surgery is essential for restoring hearing in individuals with severe sensorineural hearing loss. Accurate placement of the electrode within the cochlea is essential for successful auditory outcomes and minimizing complications. This study aims to analyze the relationship between the round window niche (RWN) alignment, its visibility during surgery, and the impact on surgical techniques and outcomes.
