\"469156185\"<\/a>You may have recently read news stories about dental x-rays being linked to benign brain tumors.\u00a0 We want to clarify a few points and assure you that every reasonable precaution is being taken to ensure your safety and minimize potential risks.\u00a0 For years, the recommendations concerning radiographic frequencies\/techniques have been governed by a concept called ALARA (As Low As Reasonably Allowable).\u00a0 This means that you take x-rays at the lowest possible settings to obtain diagnostic radiographs, as well as taking them only when necessary.\u00a0 When are they necessary?\u00a0 According to the American Dental Association\/FDA Guidelines there are many differences based on age, previous cavity experience and risk factors.<\/p>\n

For new patients to our practice, baseline radiographs are necessary to determine current dental health and risks.\u00a0 If you have recent DIAGNOSTIC radiographs from your previous dentist, this may not be necessary.\u00a0 In this instance these x-rays are used to determine if there is decay between your teeth (which cannot usually be seen during a routine exam) and to check bone levels for signs of periodontal disease.\u00a0 Also radiographs are necessary to diagnose abscesses in patients having toothaches.<\/p>\n

For recall patients with visible decay or increased risk of decay there are two different recommendations for children\/teens and adults.\u00a0 In children and teens x-rays are indicated every 6-12 months.\u00a0 In adults this increases to every 6-18 months.\u00a0 This range means that it is on a case-by-case basis depending on risk factors.<\/p>\n

For recall patients with no visible decay and not at an increased risk for decay there are three groups.\u00a0 For children the interval is 12-24 months.\u00a0 For teens the interval is 18-36 months and adults are 24-36 months.<\/p>\n

The news story reported that most patients only needed x-rays every 3 years.\u00a0 As you can see, this frequency only applies to adults with little to no risk factors.\u00a0 According to Dr. Donald O\u2019Rourke, an associate professor of neurosurgery at the University of Pennsylvania , it is also important to note that there is around a 20-25 year delay in radiation induced meningioma formation.\u00a0 The 1433 study participants mean age was 57, meaning that they were x-rayed using older technology.\u00a0 Digital radiographs have drastically cut radiation exposures.\u00a0 The study also relied on patient\u2019s memories of whether they had received regular x-rays during the decades preceding the study, including during their childhood.\u00a0 Self-reporting of this frequency also leaves great room for error.<\/p>\n

The amount of radiation that we are exposed to from dental X-rays is very small compared to our daily exposure from things like, cosmic radiation and naturally-occurring radioactive elements (for example, those producing radon).<\/p>\n

The table below compares our estimated exposure to radiation from dental X-ray with other various sources. As indicated below, a millisievert (mSv) is a unit of measure that allows for some comparison between radiation sources that expose the entire body (such as natural background radiation) and those that only expose a portion of the body (such as X-rays).<\/p>\n
