A comparison of the efficacy of topical application of Lignocaine Hydrochloride 5% gel and Bupivacaine Hydrochloride 5% gel for extraction of teeth

Abstract

Background With the advancements in dentistry the treatments are done with high perfections and patient comfort. Noninvasive, methods reduce fear and anxiety of the patient on phobia of syringes and injections. Topical anesthesia satisfies all the above criteria. Aim and objective Comparison of the efficacy of topical application of lignocaine hydrochloride 5% gel and bupivacaine hydrochloride 5% gel for extraction of teeth. Materials and methods Lignocaine hydrochloride 5% gel and bupivacaine hydrochloride 5% gel are prepared with carbopol (thickening agent). 510 extractions with lignocaine hydrochloride gel 5% and bupivacaine hydrochloride gel 5% in equal numbers was undertaken. Parameters of onset of anesthesia, peak effects, pain, and disappearance of numbness, local irritation, bleeding and periodontal status of teeth to be extracted were taken into consideration. Results Onset and peak effect were faster with 5% lignocaine hydrochloride gel. 5% bupivacaine hydrochloride gel had longer duration of analgesia. Patients experienced more pain with bupivacaine. Grade 1 mobile posterior teeth were painful during extraction. Conclusion 5% lignocaine hydrochloride gel is better than 5% bupivacaine hydrochloride gel as a topical anesthetic for extraction of grade II and grade III mobile teeth.

Comparison of efficacy among various topical anesthetics: An approach towards painless injections in periodontal surgery

“…Onset is measured by probing the free gingiva or attached gingiva and alveolar mucosa every minute. [ 1 ] The other objective symptoms such as superficial probing, deep probing and gingival detachment were assessed with a sharp probe. After application, 3 min duration was given before infiltration anesthesia using 2% lignocaine (1:80,000).…”

Comparative Effect of Topical Local Anaesthetic Spray & Gel in the Reduction of Pain on Periodontal Probing in Individuals with Untreated Chronic Periodontitis

“…The advantages of topical gels include better localization of drug in comparison with ointments and solutions, better control over systemic drug absorption, greater bioavailability and reduction indosage. 16 In addition a flavoured gel is better accepted by children. 17 However, gels get diluted in the mouth with time, resulting in is difficulty in maintaining prolonged mucosal contact resulting in inadequate anesthesia.…”

“…21 Despite these disadvantages, lignocaine gel and spray are commonly used in clinical practice than adhesive patches or disks as they increase the cost of the treatment phenomenally. 16…”

Efficacy of Lignocaine in Gel and Spray form during Buccal Infiltration Anesthesia in Children: A Randomized Clinical Trial

“…Topical anesthetic spray and gel have both advantages and disadvantages. The advantages of topical gels include better localization of drug in comparison with ointments and solutions, better control over systemic drug absorption, greater bioavailability and reduction in 17 In addition a flavored gel is better accepted by children. 18 However, gels get diluted in the mouth with time, resulting in is difficulty in maintaining prolonged mucosal contact resulting in inadequate anesthesia.…”

“…21 Despite these disadvantages, lignocaine gel and spray are commonly used in clinical practice than adhesive patches or disks as they increase the cost of the treatment phenomenally. 17 It can be inferred from the results that, as long as standard techniques of local anesthesia administration are followed, it remains to the discretion of the clinician to choose the formulation of lignocaine as a topical anesthetic agent when dealing with a child patient. The clinician may consider patient preference which however was not evaluated in this study.…”
