Special braces analyse tooth-friendliness of foods

A study by Dr. Car­men Gonzales, et al investigated the effect of systemic fluoride intake from birth to 12 weeks on orthodontically induced root resorption and tooth movement in rat mo­lars. Fifty male rats were randomly di­vided into the following 5 groups: a neg­ative control group that re­ceived no so­dium fluoride and had no tooth movement; a positive control group that re­ceived no sodium fluoride but had tooth movement; and 3 experiment­al groups that received 45-ppm sodium fluoride from birth to 2, 4, and 12 weeks, respectively. At week 10, a 50-g nickel-titanium coil spring was ap­plied to the maxillary left first molar for 2 weeks. At week 12, movement of the maxillary first mo­lars was measured in relation to the maxillary second molar on digitized cephalometric radiographs. Mesial and distal roots were examined by using scanning electron and 3-dimensional laser microscopes. The study found that fluoride reduced the depth, volume, and roughness of the resorption craters in the experimental groups. Yet, the area was similar to that in the positive control group. The longer fluoride was administered via drinking water, the smaller the amount of tooth movement ob­served. It concluded that fluoride in drinking water from birth reduced the severity of orthodontically induced root resorption, but the amount of tooth movement was also decreased.

The state of oral health in New York City may soon be on the rise.

City health officials voted, 8-0, in favor of banning 16-oz soft drinks. New York City mayor Michael Bloomberg brought up the legislation earlier this year.

The goal behind this legislation was to lower obesity rates, which have become a major problem in the United States. Without consuming sodas in the same large quantity as in the past, oral health will likely improve. The amount of sugar in soda, especially 16-oz serving sizes, is extremely problematic for one’s dental health.

A standard size soft drink contains 12 teaspoons of sugar on average.

Sugar results in many oral health problems, including gingivitis and decay. Plaque eventually develops from the bacteria, which damages the tooth enamel.

A University of California study has determined that soft drink consumption has continually gotten worse during the last 50 years, which has adversely impacted oral health as a whole. Excessive sugar consumption results on obesity, in addition to various oral health problems.

Fashion braces have become a new trend in Asia. The problem is no one figured to check the health ramifications.

Health experts in Indonesia, Thailand and China have warned against wearing the fake fashion braces.

The fake braces have become popular amongst teenagers based on the high cost of orthodontics. The braces can be purchased online or in open-air markets. The braces are sometimes fitted at beauty salons.

The braces appear to be harmless but there have been two recent deaths linked to the braces. In Thailand, the braces have been banned based on a death of a teenage boy. The death resulted from an infection in the thyroid glands that led to heart failure.

People in Thailand now caught selling the braces may face a jail sentence up to six months. If a person is found to be importing these braces, the person could face up to a year in jail.

The problem with the braces stems from the wiring they use. The wiring is made of lead, which can cause major health problems if it enters the wrong part of the body.
