Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2018, Vol 7, Issue 13
Abstract
BACKGROUND Local anaesthesia is the back bone of dentistry, as it allays the most common fear of pain among the dental patients. Many techniques were available to achieve anaesthesia for posterior maxilla. We compared two techniques of posterior superior alveolar nerve block (PSANB), its efficacy in achieving anaesthesia in posterior maxilla. Aim- The aim of the study was to compare the efficacy of “the straight needle technique” with that of the “bent needle technique” for PSANB. MATERIALS AND METHODS This is a randomised double-blinded trial. A group of 100 patients were randomised and divided into two categories, each consisting of 50 patients. Group A patients received PSANB via straight needle technique, while Group B patients received PSANB via bent needle technique. A 26-gauge long needle (38 mm) was used for the study. 2 mL of 2% lignocaine hydrochloride with 1:200,000 adrenaline was used to give the block in both the groups. Objective symptoms were evaluated by a single investigator. Cold test using ice was used to evaluate pulpal status of the patients. Data obtained was subjected to statistical analysis. Sample size was considered conveniently. RESULTS Out of the 100 nerve blocks, 14 failed (Group A: 3 and B: 11), suggesting technique A (Straight Needle Technique) was more successful than B (bent needle) in this study and this was statistically significant (p= 0.021). No statistical difference was noted between the two groups in obtaining gingival anaesthesia in the first molar region, also in second and third molar regions. We did not encounter any complications in our study. CONCLUSION The study concludes that the PSANB using the straight needle technique can be safely and routinely used to achieve profound anaesthesia in the maxillary molar regions.
