•••6••• Innovationen Regrowing dental tissue with stem cells Researchers developed a procedure to revitalise “dead” teeth affected by trauma during childhood N early half of children suffer injuries to a tooth during childhood. When that trauma affects an immature permanent tooth, it can hinder blood supply and root development, resulting in a “dead” tooth. Usually, the standard of care procedure was apexification that encourages further root development, but it does not replace the lost tissue from the injury and causes root development to proceed abnor- mally. New results of a clinical trial, jointly led by the University of Pennsylvania and the Fourth Mili- tary Medicine University in Xi’an, China, suggest that there is a more promising path for children with these types of injuries: Us- ing stem cells extracted from the patient‘s baby teeth. “This treatment gives patients sen- sation back in their teeth. If you give them a warm or cold stimula- tion, they can feel it; they have liv- ing teeth again,” says professor Songtao Shi, Penn’s School of Den- tal Medicine. He has been working for a decade to test the possibilities of dental stem cells after discov- ering them in his daughter’s baby tooth. He has learned more about how these dental stem cells, offi- cially called human deciduous pulp stem cells (hDPSC), work and how they could be safely employed to regrow dental tissue (pulp). The Phase I trial, conducted in China, enrolled 40 children who had each injured one of their per- manent incisors and still had baby teeth. Thirty were assigned to hDPSC treatment and ten to the control treatment, apexification. Those that received hDPSC treat- ment had tissue extracted from a healthy baby tooth. The stem cells from this pulp were allowed to re- produce in a laboratory culture, and the resulting cells were implanted into the injured tooth. Upon follow- up, the researchers found that pa- tients who received hDPSCs had more signs than the control group of healthy root development and thicker dentin, the hard part of a tooth beneath the enamel. Blood flow increased as well. “For me the results are very exciting,” Shi says. The stem cell therapy proves efficient for trau- matised teeth.

The combination of scanners, dental design software and 3D printers is sweeping the industry. With the introduction of the Sprin- tRay Pro we have a range of 3D printing solutions to add to the hun- dreds of MoonRay 3D printers al- ready installed throughout Europe running dental applications every day. These advanced 3D printers enable the production and process of dental models, surgical guides, crown and bridges, indirect bond- ing trays, guards and splints as well as digital dentures. The range of bio-compatible resin products now available provides many of the solutions to enhancing patient service and reducing waiting times in a chairside environment. For efficient dental scanning at IDS we will be showing and demonstrat- ing the latest range of Shining 3D scanners including the Autoscan DS-EX and Autoscan DS-EX Pro intended for data capture used in restorations, orthodontics and im- plants. For those looking for a chairside solution we will be introducing the brand new 3DISC Heron intraoral scanner. Very lightweight, with ro- tating tip and ergonomic design the Heron is very easy to use. As European wide distributors we support, train and advise on the use of the products as well as providing for any repair and servicing require- ments. Come and see the future at our stand in Hall 3.1 at K68 L69 Shining 3D Autoscan
