Abstract
BACKGROUND: High-concentration topical fluorides are used commonly to with compromised salivary function due to irradiation and chemotherapy.
CASE DESCRIPTION: The authors describe a 50-year-old man with previously treated cancer who was using tray-applied topical fluoride gel. He complained of gastric symptoms, difficulty in swallowing, leg muscle soreness and knee joint soreness. A computed tomographic scan revealed thickening of the esophageal walls. An upper endoscopy revealed abnormal motility. The motility test indicated high-amplitude peristalsis and hypertensive lower esophageal sphincter, and urine testing indicated high levels of systemic fluoride. The patient’s fluoride regimen was altered, and within a short period his urinary fluoride levels returned to normal and his symptoms resolved.
CLINICAL IMPLICATIONS: Clinicians prescribing home-applied high-concentration fluorides need to be cognizant of the symptoms of fluoride toxicity, carefully monitor the patient’s compliance with the treatment regimen, and adjust the dosage or mode of application to control the total ingested dose of fluoride.

Topical fluorides: effects on physiologic and biochemical processes
The ingestion of fluoride from dentifrices or mouthrinses can contribute substantially to the total daily intake of the ion, even in communities that provide optimally fluoridated drinking water. It is concluded that the frequent and unsupervised use of these products by children six years of age or younger, especially those living in

Revisiting Fluoride in the Twenty-First Century: Safety and Efficacy Considerations.
Over 100 years of scientific literature is available which describes the long relationship between dentistry and the many possible applications of fluoride anion (F-) as successful therapeutic strategies. To date, systemic introduction of fluoride via water, milk and salt fluoridation, and fluoride-containing tablets, has been employed. Post-eruption topical fluoride products

Recovery from skeletal fluorosis (an enigmatic, American case)
A 52-year-old man presented with severe neck immobility and radiographic osteosclerosis. Elevated fluoride levels in serum, urine, and iliac crest bone revealed skeletal fluorosis. Nearly a decade of detailed follow-up documented considerable correction of the disorder after removal of the putative source of fluoride (toothpaste). INTRODUCTION: Skeletal fluorosis, a crippling bone

Fluoride in dental products: safety considerations
This review summarizes the nature of acute fluoride toxicity, its time-course, and the fluoride doses that are involved. The generally accepted "certainly lethal dose" range for 70 kg adults, i.e., from 5 to 10 g of sodium fluoride or from 32 to 64 mgfluoride/kg, is discussed. Based on recent case reports of fluoride-induced fatalities, it is concluded

Early diagnosis and complete recovery from fluorosis through practice of interventions
OBJECTIVES: The objective of this communication is to disseminate scientific and technical information for early diagnosis of Fluorosis; recent developments in care and management of patients of Fluorosis. Material and Methods: Body fluids collected from patients suspected of Fluorosis referred by hospitals, samples of drinking water used by them are the

Fluoride-Induced Damage to Gastric Mucosa in Human Clinical Trials
When fluoride has been used (at doses of 18-34 mg/day) as an experimental treatment for osteoporosis, gastric pain is one of the two main side effects consistently encountered. To better understand how fluoride causes this effect, researchers have sought to determine how fluoride affects the tissue that lines the gastrointestinal tract. In a

Side Effects from Fluoride Gels: Gastric Distress
Gastric distress -- including nausea, pain, and vomiting -- is one the most common side effects from professional application of "fluoride gels" at the dentist. Patients receiving fluoride gels can swallow more than 20 mg of fluoride from a single treatment -- doses that far exceed the doses that can

Fluoride & Osteoarthritis
While the osteoarthritic effects that occurred from fluoride exposure were once considered to be limited to those with skeletal fluorosis, recent research shows that fluoride can cause osteoarthritis in the absence of traditionally defined fluorosis. Conventional methods used for detecting skeletal fluorosis, therefore, will fail to detect the full range of people suffering from fluoride-induced osteoarthritis.

Acute Fluoride Exposure from Fluoride Gels
Fluoride gel (i.e., 1.23% APF) is an acidic, highly concentrated fluoride treatment that dentists apply to patients teeth about two times a year. The gel contains 1.23% fluoride, which equates to 12.3 mg of fluoride for every 1 mL. Since dentists apply anywhere from 4 to 8 mL of gel

Gastrointestinal Problems Among Individuals with Skeletal Fluorosis
Humans suffering from skeletal fluorosis are known to suffer from an increased occurrence of gastrointestinal disorders. When fluoride intake is reduced, these gastrointestinal problems are among the first symptoms to disappear. The following are some of the studies that have examined this issue: "It is clear from the observations presented in this article
