Millions of people have bad teeth replaced with implants. Often following the procedure, they are unable to chew food for up to six months, until the implant has become fixated in the bone. Now, for the first time, a drug coating that has been tested on humans allows titanium screws to adhere to the bone better and faster. The Link√ ping researchers behind the method report that the results are good. The study, led by Per Aspenberg, professor of orthopaedic surgery at Link√ ping University, is published in the journal Bone and was highlighted in the British Medical Journal (BMJ). The implants are screwed into the jawbone and provide purchase for artificial teeth. Using current technology, it may take four to six months before the bone surrounding the screw has healed and is strong enough so the patient can begin to benefit from surgery.

Periodontitis means "inflammation around the tooth" - it is a serious gum infection that damages the soft tissue and bone that supports the tooth. All periodontal diseases, including periodontitis, are infections which affect the periodontium. The periodontium are the tissues around a tooth, tissues that support the tooth. With periodontitis, the alveolar bone around the teeth is slowly and progressively lost. Microorganisms, such as bacteria, stick to the surface of the tooth and multiply - an overactive immune system reacts with inflammation. Untreated periodontitis will eventually result in tooth loss, and may increase the risk of stroke, heart attack and other health problems. Bacterial plaque, a sticky, colorless membrane that develops over the surface of teeth, is the most common cause of periodontal disease.
This week's issue of The Lancet describes a case report of an 82-year-old woman in Italy who died of Legionnaires disease after becoming infected with L pneumophila at her dentist. This case has prompted the authors - led by Dr Maria Luisa Ricci at the Istituto Superiore di Sanita, Rome, Italy, to call for various control measures at dental surgeries to prevent similar incidents. Suffering with fever and respiratory distress, the woman who was conscious and responsive and had no underlying disease, was admitted in February, 2011, to the intensive care unit of the "G.B. Morgagni-Pierantoni" Hospital, Department of emergency Anaesthesia and Intensive Care Unit, Forl√, Italy. Results from a chest radiography showed multiple areas of lung consolidation. A Legionella pneumophila urinary antigen test quickly diagnosed the woman with Legionnaires' disease and she was immediately given oral antibiotics (ciprofloxacin) every 12 hours.
A new warning issued by the Food and Drug Administration (FDA), states that certain electric toothbrushes may not be safe for use. On more than one occasion, the battery-powered Arm & Hammer Spinbrush, previously known as the Crest Spinbrush, has been known to break, causing pieces of the toothbrush to injure eyes, and teeth, and even choking. Ali Shumaya, M.P.H., a consumer safety officer at the FDA said: "It's important that consumers know how to avoid the risks associated with using the Spinbrush. We've had reports in which parts of the toothbrush broke off during use and were released into the mouth with great speed, causing broken teeth and presenting a choking hazard." Susan Runner, D.D.S., chief of FDA's dental devices branch commented: "Electric toothbrushes can be very effective in removing dental plaque, and so they can help prevent dental decay and gum disease.
