OBJECTIVE To evaluate the efficacy of the written explanation given to patients when obtaining informed consent for oral surgery, taking the surgical extraction of the impacted mandibular third molar as the clinical model for this study. PATIENTS AND METHODS This study included 87 patients requiring surgical extraction of an impacted lower third molar. Residents of the Oral Surgery Department...

background: because nerve stimulators are not always available for brachial plexus block, fmding the right injection spot for nerve blocks is important. in this study we used physical examination to determine the appropriate spot for injection. methods: all patients who were candidates for upper extremity surgery and were either in class asa i or asa ii, were selected. paresthesia was elicited ...

Whenever endodontic therapy is performed on mandibular posterior teeth, damage to the inferior alveolar nerve or any of its branches is possible. Acute periapical infection in mandibular posterior teeth may also sometimes disturb the normal functioning of the inferior alveolar nerve. The most common clinical manifestation of these insults is the paresthesia of the inferior alveolar nerve or men...

Spinal anesthesia is induced by injecting small amounts of local anesthetic into the cerebrospinal fluid (CSF), which solution must be capable of blocking nerve paths, and non-toxic, that is, it should not hinder the proper functioning of the bulbar centers, or interfere with the metabolic processes of the more important organs. The injection is usually made in the lumbar spine below the level ...

Paresthesia-dominant and pain-dominant subgroups have been noted in carpal tunnel syndrome (CTS), a peripheral neuropathic disorder characterized by altered primary somatosensory/motor (S1/M1) physiology. We aimed to investigate whether brain morphometry dissociates these subgroups. Subjects with CTS were evaluated with nerve conduction studies, whereas symptom severity ratings were used to all...

BACKGROUND Two methods of nerve block based on eliciting neural feedback with the block needle currently exist. The paresthesia technique uses sensory feedback to ascertain that the needle tip is close to the nerve. By contrast, a peripheral nerve stimulator makes use of motor responses to electrical stimulation. The relation of motor responses to an electrical peripheral nerve stimulator and s...

We experienced two cases of inferior alveolar nerve paresthesia caused by root canal medicaments, which were successfully relieved by microscopic endodontic treatment. In the first case, the paresthesia might have been attributable to infiltration of calcium hydroxide into the mandibular canal through the root canals of the mandibular left second molar tooth. In the second case, the paresthesia...

OBJECTIVE Paresthesia is an adverse event that may be associated with the administration of local anesthetics in dentistry. The purpose of this retrospective study was to analyze cases of paresthesia associated with local anesthetic injection that were voluntarily reported to Ontario"s Professional Liability Program (PLP) from 1999 to 2008 inclusive, to see if the findings were consistent with ...

Paresthesia is a burning or prickling sensation or partial numbness resulting from neural injury. Paresthesia resulting from periapical pathosis or various stages of root canal treatment is of great importance in the field of endodontics. The purpose of this paper is to review paresthesia caused by periapical lesions, local anesthesia, cleaning, shaping and obturation.

introduction: control of post thoracotomy pain is particularly important in prevention of post operative respiratory complications. several methods are proposed for control of postoperative pain. cryoanalgesia by freezing of intercostal nerves is able to providing long term pain relief in post operative period which probably results in cutaneous sensory changes. methods: this clinical trial stu...
