Natural tooth repair method, using Alzheimer's drug, could revolutionise dental treatments A new method of stimulating the renewal of living stem cells in tooth pulp using an Alzheimer’s drug has been discovered by a team of researchers at King’s College London. Following trauma or an infection, the inner, soft pulp of a tooth can become exposed and infected. In order to protect the tooth from infection, a thin band of dentine is naturally produced and this seals the tooth pulp, but it is insufficient to effectively repair large cavities. Currently dentists use manmade cements or fillings, such as calcium and silicon-based products, to treat these larger cavities and fill holes in teeth. This cement remains in the tooth and fails to disintegrate, meaning that the normal mineral level of the tooth is never completely restored. However, in a paper published today in Scientific Reports, scientists from the Dental Institute at King’s College London have proven a way to stimulate the stem cells contained in the pulp of the tooth and generate new dentine in large cavities, potentially reducing the need for fillings or cements. The novel biological approach could see teeth use their natural ability to repair large cavities rather than using cements or fillings. Significantly, one of the small molecules used by the team to stimulate the renewal of the stem cells included Tideglusib, which has previously been used in clinical trials to treat neurological disorders including Alzheimer’s disease. Using biodegradable collagen sponges to deliver the treatment, the team applied low doses of small molecule glycogen synthase kinase (GSK-3) inhibitors to the tooth. They found that the sponge degraded over time and that new dentine replaced it, leading to complete, natural repair. Collagen sponges are commercially-available and clinicallyapproved, again adding to the potential of the treatment’s swift pick-up and use in dental clinics.

Most Teenagers happy with their lives but schoolwork anxiety and bullying an issue Most teenagers happy with their lives but schoolwork anxiety and bullying an issue Teenagers who feel part of a school community and enjoy good relations with their parents and teachers are more likely to perform better academically and be happier with their lives, according to the first OECD PISA assessment of students’ well-being. PISA 2015 Results analyses for the first time students’ motivation to perform well in school, their relationships with peers and teachers, their home life, and how they spend their time outside of school. The findings are based on a survey of 540,000 students in 72 participating countries and economies who also completed the main OECD PISA 2015 test on science, mathematics and reading. Many students are very anxious about school work and tests and the analysis reveals this is not related to the number of school hours or the frequency of tests but with how supportive they feel their teachers and schools to be: on average across OECD countries, 59% of students reported they often worry that taking a test will be difficult, and 66% reported feeling stressed about poor grades. Some 55% of students say they are very anxious for a test even if they are well prepared. In all countries, girls reported greater schoolwork-related anxiety than boys; and anxiety about schoolwork, homework and tests is negatively related to performance. Teachers play a big role in creating the conditions for students’ well-being at school and governments should not define the role of teachers solely through the number of instruction hours. Happier students tend to report positive relations with their teachers. Students in schools where life satisfaction is above the national average reported a higher level of support from their teacher than students in schools where life satisfaction is below average. “These findings show how teachers, schools and parents can make a real difference to children’s well-being,” said OECD Chief of Staff Gabriela Ramos, launching the report in London. “Together they can help young people develop a sense of control over their future and the resilience they need to be successful in life. There is no secret, you perform better if you feel valued, if you feel well treated, if you are given a hand to succeed!” Adaptado de: <http://www.oecd.org/newsroom/most-teenagers-happywith-their-lives-but-schoolwork-anxiety-and-bullying-an-issue.htm> Acessado em 19 de abril de 2017. 18.
