Singapore boy given mouth pulp therapy - Times of India - March 16, 2011
Chennai: A boy from Singapore suffering from cerebral palsy, whose teeth had decayed, was administered anaesthesia and given a full mouth pulp therapy procedure. The procedure involves placing crowns on all the teeth instead of extracting them and leaving him toothless. The procedure was performed at Dr. Smilez advanced dental centres. The procedure which normally takes around 4 hours was done in 1.5 hours. TNN
Congratulations to Dr. Venkatesh Babu on registering for PhD at Sri Ramachandra Medical University. He will be pursuing his research in root canal revascularization.
Congratulations to Dr. Hariharan on publishing an article on dental implants in the international journal of oral and maxillofacial implants. The second article from India in the journal.
Nasal Anesthetic Spray Could Replace Dentist's Needle
A new discovery may replace the needle used to give local anesthetic in the dentist's chair for many procedures.
Boffins have reported that a common local anesthetic, when administered to the nose as nose drops or a nasal spray, travels through the main nerve in the face and collects in high concentrations in the teeth, jaw, and structures of the mouth.
The discovery could lead to a new generation of intranasal drugs for noninvasive treatment for dental pain, migraine, and other conditions, the scientists suggest in American Chemical Society's bi-monthly journal Molecular Pharmaceutics. The article is scheduled for the journal's May-June issue.
William H. Frey II, Ph.D., and colleagues note that drugs administered to the nose travel along nerves and go directly to the brain.
One of those nerves is the trigeminal nerve, which brings feelings to the face, nose and mouth. Until now, however, scientists never checked to see whether intranasal drugs passing along that nerve might reach the teeth, gums and other areas of the face and mouth to reduce pain sensations in the face and mouth.
Neil Johnson, working in the labs of Frey and Leah R. Hanson, Ph.D., at Regions Hospital in St. Paul, Minn., found that lidocaine or Xylocaine, sprayed into the noses of laboratory rats, quickly traveled down the trigeminal nerve and collected in their teeth, jaws, and mouths at levels 20 times higher than in the blood or brain.
According to the scientists, the approach could provide a more effective and targeted method for treating dental pain/anxiety, trigeminal neuralgia (severe facial pain), migraine, and other conditions.
Study Says Oral Bacteria In Pregnant Mother Can Cause Complications
Even healthy expecting women can be at risk for pregnancy problems caused by oral bacteria, researchers from Case Western Reserve University have warned.
They have begun to understand how and which bacteria from the 700 species living in the mouth are responsible for the increasing numbers of preterm and stillbirths.
Yiping Han, from the department of periodontics in the School of Dental Medicine, led the study that found several new bacteria originating in the mouth travel through the blood to cause an inflammatory reaction in the placenta and eventually cause a range of health issues from miscarriages to stillbirths.
Researchers have been baffled why oral bacteria have shown up in the placenta or amniotic fluid of pregnant women.
The researchers found that after injecting the blood in the tails of pregnant mice with saliva from healthy people and dental plaque from those with periodontal disease, oral bacteria continued to grow in the placentas after it had left the mice blood 24 hours later.
Prior to Han's work in connecting oral bacteria to the problems in pregnancy, it was thought that infections were transmitted through the vaginal tract.
Information from Han's previous studies over the past decade shows that oral bacteria can be transported through the blood when there is a cut in the mouth's lining or an oral health problem such as gingivitis or periodontitis which breaks down the defenses in the mouth's lining that block or prevent bacteria from entering the bloodstream.
According to Han, this suggests that even healthy pregnant women should be concerned bacteria that normally lives in the mouth can enter the blood stream and make their way into the placenta's immune-free environment to ignite an inflammatory reaction that can lead to premature or stillbirths.
The findings were featured in the spotlight section in a recent Infection and Immunity. The study was also reported on the home page of the American Society for Microbiology.
