Happy New year Edmonds, Shorline , and the Seattle Metro area. Hopefully, 2014 is off to a great start for everyone.

I wanted to share with our readers a study that sheds some definitive light on why the majority of people fear the dentist.Neuroscientists have found that the sounds of dental instruments , especially dental drills, evoke fear and anxiety in some people.This landmark study was presented at the November meeting for the Society for Neuroscience. This years meeting was in San Diego.

Japanese researchers found that people who fear going to the dentist show significant differences in their brain responses compared with those who were more relaxed about dental visits, according to a story by

The researchers surveyed 21 women and 13 men ages 19 to 49 to see how much they feared dental visits. The groups were then divided into high- and low-fear groups, and they underwent brain imaging with functional MRI (fMRI) systems while they heard a series of sounds, including dental drills and suction tools.

When people in the low-fear group heard dental sounds, parts of their brains in the left and right superior temporal gyri responded more than when they heard neutral sounds. The study found that dental sounds triggered more activity in the primary auditory areas of the brain.

Anxious people registered a surge of activity in the brain’s left caudate nucleus, which may play a role in learning and remembering the sounds of the dental instruments.

The study can be applied to assess the effectiveness of interventions such as cognitive behavior therapy for patients who have a strong fear of dental treatment, the researchers said.

Complete Dentistry sees this every day and the cycle can lead to serious dental disability and loss of teeth. Dr Etue treats denial anxiety every day through a kind approach and advanced training in Sedation.

Sedation allows all of these trigger sounds to be a thing of the past. In a safe and controlled environment, Dr Etue and the team at Complete Dentistry, can cure dental anxiety and allow patients to have a healthy and happy smile , with out any of the anxiety, at a price they can afford.
