Background:The extraction of tooth being the most common procedure in oral surgery should be pain free with limited dosage and limited needlepricks. Articaine being unique among amide local anesthetics contains a thiophene group, which increases its liposolubility, and an ester group which helps biotransformation in plasma. Because of the high diffusion properties, it can be used as a single buccal infiltration to extract a maxillary tooth.Aim and Objective:Objective of the study was to compare the efficacy of single buccal infiltration of 4% articaine with that of 2% lignocaine for maxillary first molar extraction.Methodology:A triple blind randomized controlled study was carried on 100 patients of age group 18-60 years who required maxillary first molar extraction, visiting the Department of Oral and Maxillofacial surgery. They were included in the study after obtaining informed consent. Buccal infiltration of 1.8 ml of anesthetic solution was given randomly to 100 patients with appropriate blinding of the cartridges. Objective signs were checked. If any additional injection was given, it was noted as type and number of rescue injection given. Postoperatively VAS score and surgeon's quality of anesthesia was noted. Duration of anesthesia was measured every 5 minutes for 50 minutes from infiltration.Results:Out of 50 patients in group A (Articaine), in 44 patients extraction was done without the need of additional injection whereas in group B(Lignocaine), 29 patients require additional infiltration on the palatal side. The VAS score values for group A were also significantly less in comparison with group B. The mean duration of anesthesia for Group A being (71.70 ± 17.82 min) in 44 patients who only received buccal infiltration.Interpretation and Conclusion:The efficacy of single buccal injection of articaine is comparable to buccal and palatal injection of lignocaine.

Extraction of mandibular third molar is one of the most common surgical procedures performed in oral and maxillofacial surgery, which results in pain, swelling, and bony defect. Many attempts are being made to improve the postoperative recovery and patient quality of life after third molar surgery. Although several materials have been used to minimize the postoperative sequelae, autologous graft is still considered as the gold standard. [1] One such autologous bone graft material with abundance of growth factors that gained popularity in recent years is platelet concentrates such as platelet-rich plasma (PRP) and protein-rich fibrin (PRF). [2] The earlier studies found that the growth factors present in PRF and PRP enhance the healing and improve the postoperative recovery. [3,4] PRP is an autologous concentrate of platelets suspended in plasma, which contains vital growth factors such as platelet-derived growth factors and transforming growth factor-beta 1 and 2 and vascular endothelial growth factors, all of which positively influence the repair and regeneration of tissues. [5,6] It is prepared by a two-stage centrifugation procedure

Intraocular foreign bodies (FBs) are common ocular injuries reporting to the emergency services all over the world. The authors highlight the findings and surgical management of a case of intralenticular metallic FB following an injury while using chisel and hammer. The ocular path of the FB (2 mm) could be traced from a self-sealed corneal perforation, extending through the anterior capsule rupture, terminating at the posterior capsule, forming a posterior capsule tent with a part embedded in clear lens. Preoperative ultrasound biomicroscopy gave clues on posterior capsule integrity and the exact site of FB, and helped prognosticate and plan the surgical management of the case. The ‘locked-in’ FB was extracted after clear lens aspiration and posterior capsulorrhexis. The posterior capsule acted as a natural barrier between anterior and posterior segment, where the FB was found embedded.
