Objectives: Appropriate and accurate local anesthetic (LA) techniques are indispensable in the field of oral and maxillofacial surgery to obtain a satisfactory outcome for both the operating surgeon and the patient. When used alone, the inferior alveolar nerve block (IANB) technique requires supplemental injections like long buccal nerve block for extraction of mandibular molars leading to multiple traumatic experiences for the patient. The aim of this study was to anesthetize the inferior alveolar, lingual, and long buccal nerves with single-needle penetration requiring a minimal skillset such as administering a conventional IANB through introduction of the Benny Joseph technique for extraction of mandibular molars. Materials and Methods: This was a prospective study conducted in the Department of Oral and Maxillofacial Surgery, Kunhitharuvai Memorial Charitable Trust (KMCT) Dental College, Calicut, India. The duration of the study was 6 months, from June to November 2017, with a maximum sample size of 616 cases. The LA solution was 2% lignocaine with 1:100,000 adrenaline. The patients were selected from a population in the range of 20 to 40 years of age who reported to the outpatient department for routine dental extraction of normally positioned mandibular right or left first or second molars. Results: Of the 616 patients, 42 patients (6.8%) required re-anesthetization, a success rate of 93.2%. There were no complications such as hematoma formation, trismus, positive aspiration, and nerve injuries. None of the cases required re-anesthetization in the perioperative period. Conclusion: The Benny Joseph technique can be employed and is effective compared with conventional IANB techniques by reducing trauma to the patient and also requires less technique sensitivity.

This paper demonstrates the implementation of a QPSK/Time Division Multiple Access (TDMA) satellite receiver using short preamble-based synchronization in the presence of timing, frequency and phase offsets, and with Additive White Gaussian Noise (AWGN). The detection and estimation of synchronization parameters of the received signal, i.e., frequency, phase and symbol timing, are highly dependent on the preamble of the burst. Moreover, computational complexity and acquisition time of the receiver are directly proportional to the preamble length. The implemented receiver uses a 64-bit short preamble for synchronization and gives better bit error rate (BER) performance at low signal to noise ratio (SNR), close to -3dB. The functional verification of the synchronization algorithm is done using Matlab simulations and the algorithm implementation uses fixed-point C. The receiver design has been prototyped for 4 TDMA channels in Texas Instruments (TI) multi-core C66x DSP. The design and implementation of this receiver have been done for C-DOT indigenous satellite project.

Objectives: The goal of the study was to investigate the clinical effects of amoxicillin-clavulanic acid (500+125 mg) with metronidazole 400 mg ad-ministered three times daily (Group I) versus azithromycin 500 mg administered once daily and with metronidazole 400 mg three times daily (Group II) for the prevention of postoperative infection following mandibular third molar surgical removal. Materials and Methods: The study design was a single-center prospective study. Patients who reported to the Department of Oral and Maxillofacial Surgery between February 2015 and January 2017 for removal of mandibular third molar were screened, and 108 patients were chosen. One surgeon carried out all procedures. Patients were prescribed antibiotics until the two groups contained a similar number of cases. Results: Our data showed that Group II had fewer incidences of surgical site infection, but with no statistical significance. Conclusion: Although both treatments are used routinely after removal of the mandibular third molar, neither is significantly better than the other.
