What local anesthetics cause paresthesia?

number of reported cases involving articaine increased markedly, and articaine became the local anesthetic most reported to be associated with paresthesia across the entire study period.

Can articaine be used for nerve block?

These papers include studies of both infiltration and nerve block anaesthesia. Other authors concluded that articaine has a faster onset than lidocaine,11 and a meta-analysis has proved that articaine is 1.6–3.5 times more potent than lidocaine.

Is articaine a local anesthetic?

Within the rich local anesthetic drugs available in dentistry for the prevention and management of pain 4% articaine solutions achieve highest level of anesthetic potency and lowest systemic toxicity in all clinical situations, prior to its superlative physicochemical characteristics and the pharmacological profile.

Can local anesthesia cause nerve damage?

Inferior alveolar, mental and buccal nerves can also be affected due to local anaesthesia. Of these buccal nerve damage is the most rare. In addition to total or partial anaesthesia, altered sensation can mean deep, burning pain or flushing over the associated cheek.

Which is better for paresthesia prilocaine or articaine?

Garisto et al. found that anesthetic solutions used in dentistry with a high concentration of active substance (4%), i.e. prilocaine and articaine, have a significantly higher association (factors: prilocaine 7.3, articaine 3.6, p <0.0001) with the development of paresthesia than those of lower concentration (2%, e.g. lidocaine).

How is articaine related to neurologic adverse events?

A number of reports claim to provide a basis for the opinion that articaine is related to a higher frequency of neurologic adverse events like paresthesia, demanding a change in the recommendations for usage. However, when going into scientific detail, this claim seems to lack the level of evidence needed for such extensive changes.

Which is better articaine or other local anesthetics?

To minimize exposure of the fetus to the effects of the local anesthetic drug, a drug with a shorter elimination half-life is preferred. The 27-minute half-life of articaine is preferable to the 90-minute or greater half-life of the other available local anesthetics.

Are there any adverse reactions to paresthesia in Canada?

Considering about 30 million dental local anesthetic injections per year in Canada, 20 adverse reactions of paresthesia in 25 years have to be classified as negligible (CADRMP Adverse Reaction Database). Remembering the PLP reports ( Gaffen & Haas, 2009; Haas & Lennon, 1995 ), the discrepancies compared to the Health Canada reports become obvious.
