Rare Genetic Trait Discovered in Skull

The skull of a man who likely had trouble eating was recently discovered.

Experts at the University of Saskatchewan dug up the skull of a man afflicted with agenesis—a condition in which the two central bottom teeth never form. The skull was recovered in modern-day Siberia and the Bronze Age settler was likely buried about 4,000 years ago. The man most likely died due to an arrowhead fragment embedded in his jaw.

The agenesis gene is extremely rare. Experts say it only impacts 0.5 percent of people.

The experts used radiocarbon dating to determine that the skull belonged to a male who was in his late 30s or was around 40.

What’s the Right Age for a Dental Visit?

Parents don’t know enough about dental care as they should.

A recent study of nearly 500 parents with children younger than 12 was conducted to see how much they knew about dentistry. The results showed that about half of the parents didn’t take their children to visit the dentist on a regular basis.

There were 20 percent of the parents that incorrectly thought that they only had to take their children to the dentist when their teeth appeared. Also, only half of fathers and 63 percent of mothers made sure their children regularly brushed their teeth.

Substance May Provide Boost to Enamel

It may be beneficial to your health if you eat more dark chocolate.

A dentist from Beverly Hills, Calif. claims that a bitter power found in dark chocolate, theobromine, can actually harden the enamel. This would add protection to the teeth against the possible impact of staining.

Milk chocolate, however, would not have the same effect based on its high sugar content that causes bacteria and bad breath.

Dr. Harold Katz also states that cheese, green tea and strawberries have a beneficial impact when it comes to whitening teeth. The foods, just like dark chocolate, produce the best results when consumed early in the day after plaque piled up over night.

Gum Disease Bacteria May Hamper Immune System

University of Pennsylvania researchers made a new discovery about the impact of periodontitis.

Periodontitis often causes dysbiosis, which is a two-fold manipulation of the human immune system that diminishes the immune system’s effectiveness.

The information appears in the journal Cell Host & Microbe. The periodontal bacterium Porphyromonas gingivalis impacts two pathways while eliminating immune cells and maintaining their ability to produce inflammation. This saves the neutral gum bacteria from immune system clearance.

But it also makes way for dysbiosis, producing bone loss and inflammation. The broken down products feed into dysbiosis. The resulting cycle, which is buoyed by the combination of inflammation and dysbiosis, worsens periodontitis.

Coffee Could Lead to Healthy Teeth

There may be a newly discovered benefit to drinking coffee.

Recent studies suggest that regularly drinking coffee keeps teeth healthy and clean. The information was determined by a team at the Federal University in Rio de Janeiro.

The caffeine helps to eliminate harmful bacteria and plaque.

The researchers looked at baby teeth containing the robusta coffee bean, which is grown in Brazil and Vietnam. They concluded that the bean aided in getting rid of a film of bacteria on the teeth, serving to thwart the onset of plaque.
