Abstract:
The aim of this study was to evaluate the preclinical use of a training model in local anesthesia teaching on the subsequent clinical administration of a local anesthetic. Sixty-five dental students gave their first injection to a fellow dental student: twenty-two students after previous experience on a training model and forty-three without this training. After the injection, the opinions of both the student who performed the injection and the recipient were explored by questionnaires. Use of a training model did not affect the self-reported opinion of the students who performed the injection. However, the recipients of the injection considered students who exercised on the training model significantly more confident and calm, and reported a near-significant decrease in level of pain during insertion of the needle and feeling of a tingling lip. These results suggest that use of preclinical training models in local anesthesia teaching may have beneficial effects.

Local anesthetics are amphiphilic molecules consisting of a hydrophobic aromatic part linked to a hydrophilic group by an ester or amide linkage. They are weak bases and are usually available as salts, which increases their solubility and stability. Once administered, LAs exist in the body either...

Cocaine is an ester of benzoic acid and methylecgogine. It is used to anesthetize and vasoconstrict locally. Currently, it is used primarily for topical applications. It is beneficial for surgeries on the upper respiratory tract, providing anesthesia and shrinking the mucosa. Cocaine in the form of cocaine hydrochloride is...
