In a recent study, researchers from Thailand and Japan investigated how sensitive various restorative materials were to discoloration from coffee. Just like natural teeth, restora- tive materials are susceptible to discoloration from certain foods and beverages with high staining properties, including coffee, tea and red wine. In order to avoid dis- coloration over time, surface qual- ity is thus essential for the success of restorative treatments. New CAD/CAM composite resin blocks are industrially po- lymerised under standardised parameters at high temperature and pressure to achieve optimum properties at the microstructural level and a high degree of conver- sion. As a result, material charac- k k c c o o t t s s r r e e t t t t u u h h S S / / 9 9 2 2 7 7 6 6 1 1 0 0 3 3 3 6 6 6 © Coffee is one of the world’s most popular beverages; however, it is known for its tooth staining properties.

In the study, researchers from the Tokyo Medical and Dental Uni- versity in Japan and the Chula- longkorn University in Bangkok aimed to evaluate how modern composite resin block materials The researchers measured the change in colour in eight CAD/ CAM blocks, including ﬁ ve com- posite resin blocks (Block HC, SHOFU; CERASMART, GC; GRADIA Block, GC; KZR-CAD Hybrid Resin Block, Yamamoto Precious Metal; Lava Ultimate, 3M ESPE), one hy- brid ceramic block (VITA ENAMIC, VITA Zahnfabrik), one PMMA block (Telio CAD, Ivoclar Vivadent) and one feldspathic ceramic block (VITABLOCS Mark II, VITA Zahn- fabrik), and four conventional composite resins. ” Page 2 LONDON, UK: A new method of de- tecting bacteria during root canal therapy could eradicate the need for follow-up appointments and prevent treatment failure, accord- ing to a new study. The SafeRoot device, created by a team of re- searchers at King’s College London Dental Institute, enables rapid bacterial detection inside the root canal through ﬂ uorescent stain- ing and microspectroscopy, en- suring the procedure has been successful and reducing the need for tooth extraction or surgical in- tervention. During trials, the re- search team was able to success- fully detect bacterial cells after just 3 minutes of testing. “SafeRoot will reduce the time for root canal completion and will in- crease the success rate of treat- ments by letting the dentist know when it’s safe to proceed with ﬁ ll- ing the tooth,” said Professor of Bi- omaterials and Restorative Den- tistry Tim Watson from the Dental Institute.

They replicated the ma- terial by sequential growth of zinc oxide nanowire carpets, fol- lowed by layer-by-layer deposi- tion of a polymeric matrix around these. Using computer modelling, the researchers con- ﬁ rmed that the structure of the synthetic enamel acted like natu- ral enamel, diffusing the forces from vibrations through the in- teraction between the nanowires and polymer. Despite these posi- tive results, automation of the production of the material will be challenging, they said. The Structo OrthoForm presented at the 2017 International Dental Show. The device is the ﬁ rst dentistry-speciﬁ c 3-D printer tailored for orthodontic applications. ” BUSINESS Page 4 Higher tooth loss risk Dental care in MS patients Elderly Japanese residents who were forced out of their homes by the 2011 earthquake and tsunami disaster may be at greater risk of tooth loss, a survey by Tohoku University has found. Factors neg- atively affecting dental health were stress, ﬁ nancial problems, di- etary changes and a lack of oppor- tunities to brush teeth, it found. Researchers from Queensland have found that most multiple sclerosis patients perceived dental care in Australia as inﬂ exible and not tailored to individual experi- ences of the disease. Among other problems, patients reported ex- periencing difﬁ culties accessing dental care, including transport and ﬁ nancial barriers.
