How to overcome failed local anaesthesia
No full textLocal anaesthetic failure is an unavoidable aspect of dental practice. A number of factors contribute to this, which may be related to either the patient or the operator. Patient-dependent factors may be anatomical, pathological or psychological. This paper considers the reasons for unsuccessful dental local anaesthetic injections and describes techniques which may be useful in overcoming failure

Supplementary routes to local anaesthesia
No full textThe satisfactory provision of many dental treatments, particularly endodontics, relies on achieving excellent pain control. Unfortunately, the administration of a local anaesthetic solution does not always produce satisfactory anaesthesia of the dental pulp. This may be distressing for both patient and operator. Fortunately, failure of local anaesthetic injections can be overcome. This is often achieved by using alternative routes of approach for subsequent injections. Nerves such as the inferior alveolar nerve can be anaesthetized by a variety of block methods. However, techniques of anaesthesia other than the standard infiltration and regional block injections may be employed successfully when these former methods have failed to produce adequate pain control. This paper describes some supplementary local anaesthetic techniques that may be used to achieve pulpal anaesthesia for endodontic procedures when conventional approaches have failed. Although some of these techniques can be used as the primary form of anaesthesia, these are normally employed as \u27back-up\u27. The methods described are intraligamentary (periodontal ligament) injections, intraosseous anaesthesia and the intrapulpal approach. The factors that influence the success of these methods and the advantages and disadvantages of each technique are discussed. The advent of new instrumentation, which permits the slow delivery of local anaesthetic solution has led to the development of novel methods of anaesthesia in dentistry. These new approaches are discussed
Intra-oral topical anaesthetics: A review
No full textObjective: This review considers the use of topical anaesthetics in the mouth to reduce the discomfort of local anaesthetic injections and intra-oral operative procedures. Data sources: Electronic literature search using Pub Med, manual search of references within papers found by the primary search and manual searching of abstracts from scientific meetings. Study selection: The articles selected for this review investigate or used topical anaesthesia in dental procedures. Conclusions: The use of topical anaesthetics does not guarantee pain-free dental local anaesthesia. Efficacy is dependent upon the duration of application and the gauge of needle used. Evidence is available that the use of topical anaesthesia alone is sufficient to perform some intra-oral procedures including periodontal manipulations, operative dentistry and oral surgery. \ua9 1999 Elsevier Science Ltd.
