DHB claims on fluoridation challenged

The claim that water fluoridation reduces tooth decay by 40%, as repeated by Dr. De Wet yesterday (link below) is not supported by weight of evidence, according to a group of dentists who are taking a thorough and critical look at the research and data. FIND originated last year when a group of private dentists saw the need for critical and unbiased interpretation of evidence, and public informed consent decision making. While not claiming to represent the majority of dentists, the group is steadily growing as more dentists become interested in finding out the facts for themselves.

According to spokesperson Dr. Stan Litras, a Wellington dentist, the 2009 NZ Oral Health Survey quoted by Dr. de Wet is not a controlled, robust scientific study into fluoridation, and is inappropriate for making policy decisions on fluoridation.

Large metadata studies have concluded that if there is any benefit to children at all, it is of the order below 15%, and benefit to adults is questionable.

The vast majority of countries do not use fluoridation and yet their decay rates are the same or better than NZ, while their rates of asthma, diabetes, thyroid problems and mental distress conditions are generally lower.

The 2011 5-year-old data show that unfluoridated Rotorua has 58% percent of Maori children with no decay at all compared with 30% in fluoridated Taupo. We see a similar picture in Waikato and Counties-Manukau.

Why would they want to put extra industrial fluoride into their water and food chain?

We would like to see Dr. De Wet focusing on investigating the health effects of fluoride, and explain to us how the DHB know that toxic levels for long term ingestion of fluoride from all sources (food, beverages,toothpaste and water among others) are not being exceeded at the individual level, particularly by children, and particularly by Maori and Pacific Islanders who are at increased risk of harm due to diets which already are higher in fluoride and low in calcium.
