The new set of guidelines, issued by the American Academy of Pediatrics, for managing dental trauma, are not only helpful to the dentists, but are also very informative for parents who have to deal with such medical emergency. According to Martha Ann Keels, the lead author of...

Stable Carbon and Nitrogen Isotopes in Dental Calculus useful in Paleo-Dietary Analysis

Scientists have often depended upon materials like bone collagen, hair, muscle and finger nails for the purpose of paleo-dietary analysis. However, it is difficult to find them. Moreover, they decompose easily. Using bone for these kinds of research is a tedious task as the bone has to be repeatedly treated with acid baths to obtain the collagen. This process is expensive and many a times, the bone is entirely destroyed. Therefore, the museum curators often deny permission to use the bone for...

Massage Method of Toothpaste Application can protect against Tooth Decay

A new study was carried out in Sweden to find out the effect of using a toothpaste with a high fluoride content (5000 ppm F) or a standard toothpaste with a normal fluoride content (1450 ppm F) two to three times a day on the retention of fluoride in plaque and saliva, and on the pH drop in plaque. The research, which has been published in the journal Acta Odontologica Scandinavia, was carried out under the leadership of Dr. Anna Nordstr├Âm from the Sahlgrenska Academy at the University of...

Soft Diet leads to a Short Mandible and subsequent Dental Overcrowding

A new research, published in the Proceedings of the National Academy of Sciences of the United States of America (PNAS), has found that the size of the mandible is primarily a reflection of the diet that a person consumes predominantly. While a long and narrow mandible is associated with hunter gatherers, a short and wide mandible is found predominantly in farming populations. According to the study, the size of the mandible is affected by the type of diet and the chewing habits. The research...
