Tooth movement activates the central amygdala and the lateral hypothalamus by the magnitude of the force applied
from The Angle Orthodontist
The following research was designed to determine whether the magnitude of the force used to induce incisor tooth movement promotes distinct activation in cells in the central and lateral hypothalamus of rats. Also, the effect of morphine on Fos immunoreactivity was investigated in these nuclei.  More
 

Study shows benefits of Medtronic INFUSE Bone Graft in dental restoration
from Reuters
Medtronic, Inc. announced results of a study comparing the safety and effectiveness of INFUSE Bone Graft to autogenous bone graft when used in maxillary sinus floor augmentation. The study shows that the advantage of using INFUSE Bone Graft is that it avoids harvesting autogenous bone and the associated morbidity, cost, and increased surgical time. The results were recently shared at the joint meeting of the American Academy of Oral and Maxillofacial Surgeons and Canadian Academy of Oral and Maxillofacial Surgeons in Toronto.  More

Tankersley told the ADA House of Delegates, meeting this week at annual session in Honolulu. Tankersley, an oral and maxillofacial surgeon from Newport News, Va., and a dentist in private practice for 38 years, was installed Oct. 6 as the ADA's 146th president.  More
 

Dentinal hypersensitivity: Assessing a chronic problem
from RDH Magazine
Most frequently observed on the premolars, dentinal hypersensitivity occurs when tubules at the exposed dentin surface lead to sharp pain when exposed to a stimulus or trigger. Common triggers include hot or cold air and acidic, sweet, or sugary foods or beverages. The dentinal tubule is the portal through which stimuli gain access to the pulp. The odontoblasts and associated nerve fibers are able to detect dentinal fluid movement. Very little appears to be required to disturb and move odontoblasts and their associated pulpal nerve fiber endings into the proximal ends of the dentinal tubules.  More
 

Understanding the link between HPV and oropharyngeal cancers
from Journal of the American Academy of Physician Assistants
New studies suggest that there may be an alternative pathway for the development of oropharyngeal cancers. The high-risk types of human papillomavirus, especially type 16, are now thought to be potential etiologic agents. The concept that HPV plays a role in head and neck cancers is not new. This link has been under investigation for at least 20 years. This is a worrisome public-health concern because patients with HPV-positive OSCC are three to five years younger at diagnosis than those with HPV-negative OSCC, and they have a history of high-risk sexual behavior.  More

Influence of defect depth on resonance frequency analysis and insertion torque values for implants placed in fresh extraction sockets
from Osseo News
Clinical studies show promising outcomes with implants inserted at the time of extraction. However, this often results in an initial bone defect at the marginal region which preferably should heal for an optimal function. Therefore, monitoring of these implants is vital. The aims of this study were to determine the initial stability of implants placed into fresh extraction sockets, and to explore the correlations between the peri-implant bone levels and implant stability parameters.  More
 

Naltrexone implants more effective than oral form
from Reuters Health via National Association for Continuing Education
Naltrexone implants are more effective than oral naltrexone for helping heroin-dependent individuals stay off the drug, a small study in the Archives of General Psychiatry shows. "Sustained-release naltrexone implants appear to provide a new treatment option for patients with heroin dependence, particularly for those seeking an alternative to opioid agonist maintenance," Dr. Gary K. Hulse of the University of Western Australia in Nedlands and his colleagues conclude.  More
