Denture wearers take heart. Scientists in Japan claim they have for the first time developed a reliable way to generate new mouse teeth in a Petri dish. Although any application to humans is years away, the team hopes the new approach could eventually lead to the regeneration of entire organs in the lab.

Drug depot in a tooth

Posted by:Editor on Monday February 5th, 2007


The Fraunhofer Institute for Biomedical Engineering IBMT in Germany have developed a dental prosthesis consisting of a drug-filled reservoir, a valve, two sensors and several electronic components. Saliva enters the reservoir via a membrane, dissolves part of the solid drug and flows through a small duct into the mouth cavity, where it is absorbed by the mucous membranes in the patient’s cheeks. The duct is fitted with two sensors that monitor the amount of medicine being released into the body. The patient has to have the agent refilled every few weeks.

Treatment for periodontal pockets

British Dental Journal (2006); 201, 787. doi: 10.1038/sj.bdj.4814381

Treatment for periodontal pockets

Chlo-Site from Oraldent, is a new, simple, and efficient, safe way to treat periodontal pockets. Chlo-Site is a gel with 1.5% chlorhexidine that is capable of assuring both active and passive disinfection coverage at the site where it was applied for up to two weeks, its maker claims.

Chlo-Site, to be used in conjunction with srp, remains microbiologically active for a minimum of 15 days with effective concentrations of two types of chlorhexidine, chlorhexidine digluconate - slow release 0.5% and chlorhexidine dihydrochloric - rapid release 1.0%. This combination makes the bactericidal activity of Chlo-Site 40 - 60 times greater than the Minimum Inhibiting Concentration (MIC) for the pathogenic bacteria usually in periodontal pockets within the first week.

Its easy and ready to use gel is supplied in disposable syringes and can be applied directly into the periodontal pocket with the special periodontal needle provided for fast, accurate treatment of periodontal pockets.

Cortical Bone Collector

What is it for?
Safescraper® TWIST provides an easy method to obtain ideal autologous cortical bone for grafts in any type of defects with a minimally invasive technique

When to use it
Easy to use, Safescraper® TWIST makes autologous bone always available in any condition, both for small and large harvests

How it works
The exclusive cutting performance of the blade allows cortical shavings to be collected, while preserving maximum cell vitality, which is essential for graft integration. The bone collected is already combined with blood and ready to be positioned in the defect, or it can be temporary
maintained in aseptic conditions in the transparent chamber

Mini-blade Gracey's curettes

In recent years, modifications and advancements have abounded in hand instrument design. To chronicle these advancements, this will be the first in a series on the design and use of some of the most innovative and effective developments in hand instruments.
Mini-bladed Gracey curets are modifications of the extended shank Gracey curets. Their terminal shanks are 3 mm longer and their blades are thinner and half the length of standard and extended shank Gracey curets. The shorter, thinner blade allows easier insertion and adaptation in deep, narrow pockets; furcations; developmental depressions; line angles; and deep, tight pockets on facial, lingual, or palatal surfaces. In areas where root morphology or tight tissue prevent full insertion of the standard or extended shank Gracey blade, the mini-bladed Gracey curets can be used with vertical strokes, with minimal tissue distention, and without tissue trauma.
Mini-bladed Gracey curets have substantially improved the degree to which deep subgingival deposits of calculus and biofilm can be removed. This is due to superior access and adaptation of their blades to anatomical contours exposed by moderate to severe clinical attachment loss. In the past, the only solution in difficult-to-access areas was to use standard Gracey curets with a short, toe-down, horizontal stroke.
Micro mini-bladed Gracey curets are the latest modification of mini-bladed Gracey curets. They are now being used in Germany and are not currently available in the United States . These instruments are half the size of the currently available mini-bladed Gracey curets. They allow better access to furcations and very tight, narrow pockets and are ideal for subgingival use with the dental endoscope. This trend toward miniaturization of instruments facilitates non-surgical treatment of areas that were previously difficult or impossible to reach with standard hand instruments.

GEM 21s - First FDA approved Growth-factor in Periodontal defects

Osteohealth Company announced that GEM 21S® (Growth-factor Enhanced Matrix) has been approved by the U.S. Food and Drug Administration (FDA). GEM 21S® is a fully synthetic regeneration system for the treatment of periodontal bone defects and associated gingival recession. GEM 21S® is composed of the tissue growth factor, recombinant human Platelet-Derived Growth Factor (rhPDGF-BB), and a synthetic bone matrix, Beta-tricalcium phosphate (ß-TCP). It is the first totally synthetic product combining a purified recombinant growth factor with a synthetic bone matrix to be approved by the FDA for human application. The combination of the two components of GEM 21S ® are key to the overall effectiveness of the product. The rhPDGF-BB provides the biological stimulus for tissue repair by stimulating the proliferation and in-growth of osteoblasts, cells responsible for the formation of bone, while the ß-TCP provides the framework or scaffold for new bone growth to occur. In recognition of the unique treatment modality provided by GEM 21S®, the FDA has established it as a first-in-class product in its treatment category. More....
