This summary is based on the article published in the British Journal of Oral and Maxillofacial Surgery: Safety of local anaesthesia in dental patients taking oral anticoagulants: is it still controversial? (January 2012) Purpose of the Study To investigate the safety of local infiltration techniques and the inferior alveolar nerve block (IANB) in dental patients taking oral anticoagulants. Main Findings Bleeding as a result of the use of local anaesthesia in patients with therapeutic INR is unlikely, provided that the IANB is done correctly. IANB in patients with INR within therapeutic range is safe. Haemorrhagic complications after local anaesthesia, including the IANB (possibly even other nerve blocks), ...Read More »
This summary is based on the article published in the International Dental Journal: Clinical efficacy of antibiotics in the treatment of peri-implantitis (August 2013) Context Various treatment regimes for Peri-implantitis (PI) have been proposed in the literature. As it is known that bacteria can transfer from periodontally involved teeth to an implant, and that the microbes associated with PI resemble those of periodontal disease, local or systemic delivery of antibiotics with traditional PI treatment regimes may eliminate periodontopathogenic bacteria to a greater extent compared with when these treatment regimes are performed alone. This in turn may facilitate healing of PI ...Read More »
