The magnetic field is known to attenuate mental depression, but it is not clear on the effect of dental magnets on human brain activity. Therefore, this study was to determine the influence of magnetic field from intraoral magnets on the human brain activity by analyzing the changes in alpha waves.Materials and Methods: Twenty complete denture male patients aged between 50 and 60 years were included after their consent. The neodymium-iron-boron sintered magnet was incorporated into the existing mandibular denture bilaterally in canine region. The participants were subjected to electroencephalogram (EEG) and the output measured alpha waves at three phases: (i) without placement of magnets (WM0), (ii) 30 days post-magnet placement in the mandibular denture (WM), and (iii) after 6 months post-removal of magnets (WM6). The data obtained was skewed (non-parametric), and hence multivariate analysis using Friedman test, and bivariate analysis using Wilcoxon signed rank test and Mann-Whitney test were done to assess the significant difference among the groups. Results: The comparison of alpha waves between different phases showed a significant difference in all the pairs (p < .05) except WM-WM6. Comparison of alpha waves between right and left hemisphere showed no statistically significant difference (p > .05). Conclusion:We concluded that dental magnets had an influential effect on the alpha waves in the brain on both the left and right hemispheres. The removal of dental magnets retained the changes in brain activity even after 6 months of removal, denoting the alternative therapy to management of mental depression.

To evaluate the prevalence of different complications during and after maxillary third molar extraction. Materials and Methods: An observational study was conducted at Ruby Dental Clinic and Implant Centre, Kunnamkulam, Kerala, India from April 2018 to March 2019. Total 120 Patient who were planned for surgical extraction of maxillary third molar were included in this study. All surgical extractions of maxillary third molar were performed under local anesthesia by a qualified and experienced oral and maxillofacial surgeon. Results: A total of 120 patients of surgical extraction of maxillary third molar were carried out under local anaesthesia over a scheduled period of study. 38 patients were having intra-operative or postoperative complications. Out of 120 patients, 75 were males and 45 were female patients. Most common complications in our study were maxillary tuberosity fracture seen in 13 patients (34.2%). The second most commonly found complication was delayed wound healing 6 (15.8%), postoperative pain 5 (13.2%) and post-operative infection 4 (10.5%). Conclusion: The risk of complications in third molar surgery will always exist and increases in proportion to the surgical difficulty.
