What Everybody Ought to Know About Asthma
Dr. Teeth 23 April, 2008
(7) Comment Asthma is the most common chronic disease among children. Asthma triggers include viral infections; environmental pollutants, such as tobacco smoke; certain medications, (aspirin, nonsteroidal anti-inflammatory drugs), and sustained exercise, particularly in cold environments.
Diagnosis
History
Symptoms of asthma may include episodic complaints of breathing difficulties, seasonal or nighttime cough, prolonged shortness of breath after a respiratory infection, or difficulty sustaining exercise.
Wheezing does not always represent asthma. Wheezing may persist for weeks after an acute bronchitis episode. Patients with chronic obstructive pulmonary disease may have a reversible component superimposed on their fixed obstruction. Etiologic clues include a personal history of allergic disease, such as rhinitis or atopic dermatitis, and a family history of allergic disease.
The frequency of daytime and nighttime symptoms, duration of exacerbations and asthma triggers should be assessed.

Tooth regeneration will make fillings a thing of the past
Dr. Teeth 6 April, 2008
(4) Comment 
Scientists are developing the technology to enable teeth to regrow the crystals that make up dentin and enamel, thereby phasing out fillings and drillings completely.
The technology will evenbtually phase out fillings and drillings completely.
The goal – estimated to be at least 10 years away – is to spot tooth decay early enough that they then get the teeth to grow healthy tooth-matter over the bad spots.
The scientists are beginning to find just the right solutions of chemicals to rebuild decayed teeth, rather than merely patching their holes.
‘What we’re hoping to have happen is to catch [decaying teeth] early and remineralise them,’ said Sally Marshall, a professor at the University of California at San Francisco.
By putting a layer of the solution on individual test teeth, Marshall has already been able to remineralise some parts of the teeth.

Brushing Teeth with a Computer Game
Dr. Teeth 12 February, 2008
(3) Comment Scientists have come up with a novel idea to encourage kids to brush their teeth properly.
They’ve created a game with a webcam and basic software similar to a Nintendo Wii.
The ‘Playful Toothbrush’ is the brainchild of scientists at Taiwan University and aims to aid the tiresome task faced by dental professionals and parents everywhere – getting children to brush their teeth effectively.
With the average five year old brushing only a quarter of their teeth, the ‘learning through play’ approach may prove a winner.
LED modules containing three LEDs are mounted onto one end of the toothbrush and a web camera, mounted onto a bathroom mirror, can track this.
The camera uses computer software to track the movements of the toothbrush.
This information is fed as an input into the computer, which displays a game that the scientists have developed.
