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 ...

The purpose of this prospective, randomized, double-blind study was to compare the anesthetic efficacy of 4% articaine with 1:100,000 epinephrine to 2% lidocaine with 1:100,000 epinephrine for inferior alveolar nerve blocks in patients experiencing irreversible pulpitis in mandibular posterior teeth. Seventy-two emergency patients diagnosed with irreversible pulpitis of a mandibular posterior t...

OBJECTIVES While stimulation of the peripheral nerves increases the pain threshold, chronic pressure stimulation of the sciatic nerve is associated with sciatica. We recently found that acute pressure block of the sciatic nerve inhibits pain. Therefore, we propose that, the pain pathology-causing pressure is chronic, not acute. Here, we report a novel self-administered method: acute pressure bl...

Long acting local anaesthetics and inferior alveolar nerve block in children can cause loss of sensation and proprioception in a large area supplied by that particular nerve. Similar to the maxilla in mandible also, adequate level of anaesthesia can be achieved in the desired site of treatment by using a short acting local anaesthetic. Early return of normal sensory feedback after using short a...

INTRODUCTION Phentolamine mesylate has been reported to be an effective local anesthetic reversal agent for soft tissue but has not been studied regarding reversal of pulpal anesthesia. The authors conducted a prospective randomized, single-blind study comparing the reversal of pulpal and soft tissue anesthesia when phentolamine was administered at 30 minutes versus 60 minutes after the adminis...

paresthesia is a burning or prickling sensation or partial numbness, resulting from neural injury. the symptoms can vary from mild neurosensory dysfunction to total loss of sensation in the innervated area. only a few cases have described apical periodontitis to be the etiological factor of impaired sensation in the area innervated by the inferior alveolar and mental nerves. the aim of the pres...
