<![CDATA[There have been many articles lately bringing to light the increase in cavities in children and the possible link with bottled water. Some articles have suggested that the increase in bottled water over tap water has decreased the amount of fluoride intake thereby increasing the rate of cavities in children. This statement is not entirely true. Although decreased fluoride intake can increase your susceptibility to cavities it is only one factor in a complex scenario. Also, keep in mind that many bottled water companies do offer water with fluoride in it and also many communities do not have fluoride in their tap water. Over the years dentistry has focused on preventative care with pediatric patients. We do this by recommending good home care, fluoride use, dental sealants and regular check ups. This is only one piece of the puzzle though. One portion of care that dentists do not get to address thoroughly is a child’s diet. With an increase in high sugar and carbohydrate intake, processed foods, and children with little opportunity to brush their teeth during the day, we are seeing more and more children with cavities at a young age. Bottled water is not the enemy, as the International Bottled Water Association stated in a recent article, bottled water does not have sugar in it and is a great and healthy alternative to other bottled drinks on the market. Fluoride is just one step to help our children achieve great oral health. We also have to focus on good nutrition, home care, and regular hygiene visits to help keep our kids healthy!]]>
<![CDATA[Dental X-rays and Brain Tumors What are the Risks? There have been recent studies linking dental x-rays to common brain tumors called meningioma's. In our constant effort to keep our patients informed on the most recent dental information we assembled the facts about this study and its findings and our views on dental x-rays. The study suggests that dental x-rays, particularly when obtained frequently and at a young age, may be associated with an increased risk of an intracranial meningioma. The study compared dental and therapeutic radiation histories in 1433 patients against a control group of 1350 subjects. The study was conducted via telephone interviews with patients and information accrued via patients memory. Due to dental records being held at various offices, researchers were unable to validate the samples history due to time and financial considerations.
- The study states that: “No studies have reported on the association between use of computed tomography (CT) and meningioma risk” as well as: ” The studies that report on dental x-ray exposure are suggestive but are limited by sample size and by the inclusion of cases from time periods with higher dosing regimes than the current era”
- Meningioma’s are common benign brain tumors originating in the meninges. As reported by the Cancer Brain Tumor Registry of the United States, “Primary brain tumors represent only 2% of all cancers, with 35,000 new cases diagnosed each year in the United States,” “Meningioma’s occur at a rate of 7.8 per 100,000 per year, but only 25% are believed to be symptomatic, with the others being found incidentally.” Because the overall prognosis for this type of tumor is good and the tumors are commonly asymptomatic, only being found incidentally, many doctors do not recommend treating them and opt to observe the tumors instead.
- Dr. Elizabeth Claus, the lead author of the study reported is quoted as saying: “Our take home message is don’t panic. Don’t stop going to the dentist” and ” Our study refers to exposures in the past rather than exposures that people are receiving in this day and age”
- The American Dental Association’s position on dental x-rays is that dentists should order dental x-rays for patients only when necessary for diagnosis and treatment.
