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.

Texture.Purpose: To evaluate the efficacy of 40 mg pre-operative and 80 mg post-operative doses of intravenous methylprednisolone (Solumedrol) in the reduction of post-operative complication after surgical removal of impacted mandibular third molars. Materials and methods: A prospective randomised double blind study was carried out in The Department of Oral and Maxillofacial surgery, GITAM Dental College and Hospital, Visakhapatnam On fifty patients with impacted mandibular third molars randomly divided into two groups of twenty five patients each after obtaining the ethical committee approval. Parameters taken for consideration are swelling, pain and trismus pre-operatively, immediate post operative, 2 nd and 7 th post operative days. WBC count on pre operative and 7 th post op day. The study solution was administered intravenously just before administration of local anesthesia. Post operative dose of the drug was given 6 hours after the pre operative dose. Results: Significant difference was observed between placebo and steroid groups with respect to pain, swelling and mouth opening from pre-operative to 2 nd day. Non-significant difference was observed between placebo and steroid groups with respect to WBC counts (cells/mm3) at pre-operative, 7 th day and difference of pre-operative to 7 th day at 5% level of significance (p>0.05).
