conclusions the volume of the injected anesthetic accelerated the onset of sensory and motor block without affecting the rate of success in our patients. results the onset of sensory and motor block was significantly shorter in the 1.3% lidocaine group than in the 2% lidocaine group (p ≤ 0.05). the success rate of sensory and motor block was not different. the quality (completeness) of sensory ...

BACKGROUND AND AIM: Ocular disorder like, diplopia, mydriasis, blurred vision, ptosis, exophthalmos, and blindness (permanent or temporary) are infrequent complications of an injection of local anesthetics in mouth.The main purpose of this study was to survey the dentist’s knowledge and attitude about ocular disorders due to intra-oral anesthetics injection.<br...

QUESTIONS OF THE DAY L ocal anesthesia can be defined as loss of sensation in a discrete region of the body caused by disruption of impulse generation or propagation. Local anesthesia can be produced by various chemical and physical means. However, in routine clinical practice, local anesthesia is produced by a narrow class of compounds, and recovery is normally spontaneous, predictable, and co...

Systemic neurotoxicity due to excessive cerebral local anesthetic blood levels is one of the most severe and most frequent adverse outcome of local anesthetic use. Toxic levels are most often produced by unintentional intravenous or intraarterial injection(1,2). Toxicity can also result from the rapid absorption of drug following perineural injection. Peak blood levels are usually obtained acco...

background: injection of local anesthesia is one of the most important reasons for development of avoidance behavior in children. efforts have been performed to decrease pain perception of injection. the present research evaluated the effect of cooling the injection site on pain perception before infiltration of local anesthetics. materials and methods: a prospective single-blind crossover clin...
