A novel cosmetic product, designed to fill small to moderate facial scars, has shown promise in covering such deformities in a small group of patients. Participants were generally more satisfied with their appearance after the treatment was applied and the researchers believe it could help improve psychological wellbeing for patients whose self-esteem is affected by their scars.
In a clinical trial led by Songtao Shi of the University of Pennsylvania and colleagues in China, stem cells extracted from children's baby teeth were used to regrow the living tissue in teeth damaged by injury. The promising findings highlight the potential of dental stem cells, which could one day be used in a wide range of dental procedures or even for treating certain systemic diseases.
This research work aims to help other researchers in the field to set up an experimental bench to assess the performance of different tools for the retrieval of cement crowns, in terms of reliability, learnability and efficiency.
Routine oral care to treat gum disease (periodontitis) may play a role in reducing inflammation and toxins in the blood (endotoxemia) and improving cognitive function in people with liver cirrhosis. The study is published ahead of print in the American Journal of Physiology -- Gastrointestinal and Liver Physiology.
Since the discovery of the fossil remains of Australopithecus africanus from Taung nearly a century ago, and subsequent discoveries of Paranthropus robustus, there have been disagreements about the diets of these two South African hominin species. By analyzing the splay and orientation of fossil hominin tooth roots, researchers of the MPI for Evolutionary Anthropology, the University of Chile and the University of Oxford now suggest that Paranthropus robustus had a unique way of chewing food not seen in other hominins.
A root canal ranks high on most people's list of dreaded dental procedures, and it results in a dead tooth susceptible to further decay. Now scientists have developed a peptide hydrogel designed to regenerate dental pulp after a root canal, preserving the tooth. The researchers will present their results today at the 256th National Meeting & Exposition of the American Chemical Society.
Tooth loss is a significant health issue currently affecting millions of people worldwide. Two articles published in the September 2018 issue of the Journal of Dental Research share recent advances in bioengineering teeth.
Infection rates of high risk human papillomavirus (HR-HPV) oral infection in England are lower than expected, compared to previous US studies.
When the good and bad bacteria in our mouth become imbalanced, the bad bacteria form a biofilm (aka plaque), which can cause cavities, and if left untreated over time, can lead to cardiovascular and other inflammatory diseases like diabetes and bacterial pneumonia. A team of researchers from the University of Illinois has recently devised a practical nanotechnology-based method for detecting and treating the harmful bacteria that cause plaque and lead to tooth decay and other detrimental conditions.
Elderly individuals with fewer teeth, poor dental hygiene, and more cavities constantly ingest more dysbiotic microbiota, which could be harmful to their respiratory health, according to new research published in the journal mSphere. The findings come from a large, population-based study that identified variations in the tongue microbiota among community-dwelling elderly adults in Japan.
