Comparative Study
A clinician guide to patients afraid of dental injections and numbness.
Fears of dental injections remain a clinical problem often requiring cognitive behavioural psychology counselling and sedation in order to carry out needed dental treatment. This study, based on a national survey in Australia, compared patient concerns about numbness caused by local anaesthesia and fears of the injection itself. It also examined associations between dental fearfulness and avoidance associated with patient self-reported negative experiences and treatment need. ⋯ Finally, the association between fear of numbness and injections and dental avoidance and treatment needs has not been investigated. This study, based on survey work in Australia, aimed to compare patient concerns about numbness caused by receiving anaesthesia to that of anxiety over the receipt of needles and injections. Associations with dental fear and avoidance as well as negative experiences and treatment needs were also explored.

Randomized Controlled Trial Comparative Study
Comparison between two regional anaesthesia techniques performed by inexperienced operators: the Gow-Gates block versus the Kenneth Reed block.
The aim was to compare the efficacy of Kenneth Reed and Gow-Gates inferior alveolar nerve blocks when performed by an inexperienced operator. ⋯ Our research has demonstrated that the Kenneth Reed technique is equally effective at producing anaesthesia of the inferior alveolar nerve. Compared with conventional techniques there is a lower incidence of positive aspiration and potential for lower morbidity as the local anaesthetic is deposited further from the neurovascular bundle than when deposited near the mandibular foramen as in most conventional Inferior Alveolar Nerve Block techniques.
