1/24. Dental fluorosis associated with hereditary diabetes insipidus.

    Among the characteristics of hereditary pituitary diabetes insipidus are polydipsia and polyuria from early infancy. Drinking of large amounts of water, even with lower than accepted fluoride content, can produce fluorosis of the teeth. A mother and her four children affected by this disorder presented different degrees of fluorosis directly related to the stage at which hormonal therapy was introduced. ( info)

2/24. Esthetic improvement following enamel microabrasion on fluorotic teeth: a case report.

    enamel microabrasion is a proven method of removing intrinsic and superficial defects from teeth, establishing esthetics with minimal loss of dental enamel. This article reports one case in which two different microabrasion techniques were used to remove fluorotic stains from teeth. ( info)

3/24. Brick tea fluoride as a main source of adult fluorosis.

    An epidemiological survey was conducted in Naqu County, tibet in September 2001 to investigate the manifestations of fluorosis in adults caused by the habitual consumption of brick tea. Profiles were obtained for the total daily fluoride intake, environmental fluoride levels and average urinary fluoride concentration, and a physical examination and a skeletal radiographic study were conducted. One hundred and eleven 30-78-year-old adults were enrolled. It was found that the fluoride level of water sources in Naqu County was 0.10 /-0.03 mg/l; no evidence of fluoride air pollution was found, but the brick tea water processed foods--zamba and buttered tea--had fluoride contents of 4.52 /-0.74 mg/kg and 3.21 /-0.65 mg/l, respectively. The adult daily fluoride intake reached 12 mg, of which 99% originated from the brick tea-containing foods. The positive rate of clinical symptoms by physical examination was 89%; furthermore, 42 of the 111 subjects were diagnosed by X-ray. The positive examination rate was 83%. Although the osteosclerosis-type skeletal fluorosis (overall increased bone matrix density) affected 74%, arthropathy and arthritis affected a significant number of the patients, resulting in functional disability. The results suggest that this brick tea-type fluorosis had even more severe adverse effects on human health compared with both the water-type and coal combustion-type fluorosis that occurred in other areas of china.

4/24. Treatment of endemic fluorosis and tetracycline staining with macroabrasion and nightguard vital bleaching: a case report.

    A patient, diagnosed with a combination of level 3 endemic dental fluorosis and degree 1 tetracycline staining, was treated sequentially by macroabrasion techniques and nightguard vital bleaching. Various pairings of diamond and carbide burs, abrasive disks, rotary polishing points, and diamond polishing pastes were tested to obtain the optimal combination for macroabrasion. This conservative treatment regimen produced results that were termed "excellent" by the patient and met the goals of the dentists. ( info)

5/24. Esthetic alternative for fluorosis blemishes with the usage of a dual bleaching system based on hydrogen peroxide at 35%.

    Esthetic dental procedures in pediatric dentistry represent sources of satisfaction and realization, as much for the patient as for the professional. Lack of dental esthetics may develop psychological problems in infant as well as in adolescent patients. Blemishes produced by fluorosis appear as a challenge to the pediatric dentist and alternatives for treatment are desired. The scope of this present paper is to relate a clinical case with esthetic solution for blemishes in teeth enamel due to fluorosis. A dual system of bleaching was used (photo/chemically activated) based on hydrogen peroxide at 35% (Hi-Lite-Shofu) in a male eight-year-old patient with white fluorosis blemishes on teeth 11 and 21. The bleaching system used was efficient in bleaching teeth with white blemishes due to fluorosis, thus masking the blemishes and providing a more uniform appearance. ( info)

6/24. Using microabrasive material to remove fluorosis stains.

    BACKGROUND: Increased public access to fluoride has decreased the prevalence of caries and increased the prevalence of fluorosis staining. This article provides a case report involving a conservative method of removing fluorosis stain, as well as describes an in vitro test of the method. CASE DESCRIPTION: A healthy man sought treatment at new york University College of Dentistry for removal of severe, dark brown fluorosis staining on his anterior teeth. To remove the stain, the treating clinician used a microabrasive material, which leaves enamel intact, instead of a tooth-whitening agent, which requires removal of all affected enamel. methods: To demonstrate that enamel structure is not disturbed by the microabrasive material, the authors performed a study using scanning electron microscopy, or SEM. They viewed enamel structure under SEM at x1,000 magnification. They viewed untreated microabraded enamel and compared it with enamel that had been treated for 20 seconds with 37 percent phosphoric acid. RESULTS: An etch pattern was not discernible on the tooth treated with the microabrasive material. The enamel prisms remained intact and the cores were not exposed. CLINICAL IMPLICATIONS: Microabrasion removes intrinsic fluorosis stain effectively while protecting enamel. In this case, an enamel shade of brown not in the range of any tooth color shade guide was reduced. ( info)

7/24. Contribution of trona (magadi) into excessive fluorosis--a case study in Maji ya Chai ward, northern tanzania.

    Excessive fluoride ingestion predominantly comes from drinking water sources. However, prevalence and severity of dental and skeletal fluorosis in northern tanzania have been reported to be higher than would be expected from ingestion of fluoride through drinking water alone. This study aimed at investigating the contribution of "trona" (also locally known as magadi) a food additive, to the prevalence and severity of fluorosis in northern tanzania. The study was carried out in four villages (Embaseni, Kitefu and Ngurdoto) in Maji ya Chai ward; and Nkoanekoli in Poli ward, in Arusha region, tanzania. Analysis of fluoride concentrations was carried out in drinking water sources as well as in magadi samples. Assessment of the prevalence of dental fluorosis using Dean's Index Method was carried out for a population of 2217 pupils in four primary schools located in the case study area. Fluoride concentration in drinking water sources was found to range from 1.7 to 11.3 mg/l, while the concentration in magadi samples in case study villages were in the range of 0.21 to 0.9 mg/g. Total fluoride ingestion through magadi and water were established to be 11.74 mg/person/day in Embaseni, 36.1 mg/person/day in Ngurdoto, 10.88 mg/person/day in Kitefu and 5.7 mg/person/day in Nkoanekoli villages. Levels of total fluoride ingestion were directly correlated with Community Fluorosis Index (CFI) values, which were found to be 3.32 (in Embaseni), 3.67 (in Ngurdoto), 2.2 (in Kitefu) and 1.47 (in Nkoanekoli). The village with the highest fluoride consumption rate showed the highest CFI as well. High levels of fluoride concentrations in magadi suggest that excessive fluorosis in northern tanzania may be due to the use of magadi in food preparations. ( info)

8/24. Conservative aesthetic solutions for the adolescent and young adult utilizing composite resins.

    The demand for aesthetic procedures in today's dental arena is increasing exponentially, yet these desires often call for conservative restorative options, especially for the adolescent patient. The use of direct composite resin restorations offers the dentist the most sim-ple and cost-effective manner in which to create an aesthetic change in the anterior portion of the mouth. The combination of improved materials and innovative delivery techniques allows clinicians to reach these aesthetic goals by creating conservative and functional restorations that have excellent longevity. This article demonstrates five direct composite approaches for solving aesthetic dilemmas in the adolescent and young adult patient. ( info)

9/24. Improved esthetics with a combined bleaching technique: a case report.

    This paper describes a clinical case in which a combination bleaching technique was used to improve the appearance of the patient's discolored anterior teeth. enamel microabrasion was used first to remove superficial fluorosis stains. A home bleaching regimen was then used to lighten the overall shade of the teeth, which had appeared more yellow after microabrasion. ( info)

10/24. Macroabrasion in pediatric dentistry.

    One of the most frequent reasons for seeking dental care is discolored anterior teeth. Macroabrasion is a technique used for the removal of localized superficial white spots and other surface stains. This article has compiled three case reports with relevant clinical photographs of discolored teeth where the treatment regimen included macroabrasion alone as well as macro-abrasion in combination with anterior composite restorations.
