Tooth Extraction Without Palatal Injection
from Dentistry Today
The palatal injection is among the most feared by patients and causes more pain than injections in less dense soft tissues of the mucosa. A study was published in the March issue of Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology & Endodontics entitled "Comparison of the Efficiencies of Permanent Maxillary Tooth Removal Performed With Single Buccal Infiltration Versus Routine Buccal and Palatal Injection."More

Effective Treatment for Infective Endocarditis Using a Rigorous Hospital Management-based Approach
from Medical News Today
A clinical study carried out at Hôpital de la Timone in Marseille has demonstrated that a standardized management protocol for patients with infective endocarditis can dramatically reduce mortality rates. In 2002, a simple, rigorous and standardized protocol for therapeutic management were introduced by the team of researchers. More

Accuracy of Template-based Dental Implant Placement
from The International Journal of Oral & Maxillofacial Implants
The accuracy of a system for image-guided dental implant planning and placement based on individually fabricated oral templates was investigated in a phantom study. Materials and Methods: The study was performed on identical phantoms of a partially edentulous mandible. In one phantom mandible (the master model), pilot boreholes for dental implants were placed. Computerized tomography image data were then acquired. Using a system for template-based dental implant placement, identical boreholes were planned on the image data and then reproduced in the 10 remaining phantom mandibles. More

Teeth Stem Cells
from WGN-TV
Baby and wisdom teeth, along with jawbone and periodontal ligament, are non-controversial sources of stem cells that could be "banked" for future health needs. Harvested from the pulp layer inside the teeth, jawbone and periodontal ligament, these stem cells may one day correct periodontal defects and cleft palate, and may help restore nerve cells lost in diseases such as Parkinson's.

Senate Confirms Collins as Director of NIH
from Modern Healthcare
In a unanimous vote, the U.S. Senate confirmed the appointment of Francis Collins as the next director of the National Institutes of Health, according to HHS. A physician-geneticist known for his discoveries of disease genes and his leadership on the Human Genome Project, Collins served as director of the National Human Genome Research Institute at the NIH from 1993 until 2008.

Oxidant-Antioxidant Status in Blood and Tumor Tissue of Oral Squamous Cell Carcinoma Patients
from the National Center for Biotechnology Information
Increased oxidative and nitrosative stress associated with disturbances in antioxidant defense system have been implicated in the pathogenesis of several diseases, most notably oral cancer. The aim of this study was to evaluate the oxidant-antioxidant status in blood samples and tumor tissue in oral squamous cell carcinoma (OSCC) patients in comparison with the healthy controls. More

Scalloped Dental Implants: A Retrospective Analysis of Radiographic and Clinical Outcomes of 17 NobelPerfect Implants in Six Patients
from the National Center for Biotechnology Information
The scalloped dental implant is designed to biologically guide and facilitate interproximal bone remodeling during healing and to maintain bone height and papillae during functional loading. The design features of the scalloped implant include hard and soft tissue apposition areas, which are parallel to each other and mirror the cementoenamel junction. More

Down to the Bone
from The Age
Val Engel says she has long appreciated the need to look her best, which is one reason she spent so much money on top-quality dental implants after she started losing her teeth in her 50s. By her mid-60s, however, she had started experiencing pain in her lower jaw. "A surgeon said I had an infection in the area of the implants - and it got worse and worse," she said. Engel, now 71, had the infection drained, but the pain continued. Her jaw would not heal, and she ended up undergoing multiple operations. Even so, her problem has been almost impossible to treat, part of her jaw has died and she is still suffering five years later. More

Resin Elasticity and the Strengthening of All-Ceramic Restorations
from NIDCR
Resin luting of all ceramic restorations results in increased performance; however, the strengthening mechanism and the role of the mechanical properties of the resin are not fully understood. The hypothesis tested is that ceramic strength enhancement is dependent on the elastic modulus of the resin. Three point flexural moduli of a flowable, luting, and hybrid composite resin were characterized. Two hundred forty porcelain disks were air abraded. More

New Office, Impossible Time Frame
from Dental Economics
In 1999, I purchased a 20-year-old general practice in downtown Denver located on the second floor of a 42-story high-rise building, writes Dr. Gary Radz. We did our best to give the dated practice a face-lift to create a more modern appearance. We transitioned from an insurance-based general practice to a fee-for-service cosmetically oriented general practice. More
