Observations on the Mottled Condition of Human Teeth Endemic in a Certain Locality of Nagercoil in Travancore, S. India
A comparative study of the conditions that place and those in the adjoining are^ would show that the sectional incidence mottled enamel can be correlated with ^ occurrence of fluorides in the drinking wa , supplies. Thus, the analysis of the drinkjj1^ water supply of the afflicted persons shows ^ presence of 0.4 to 0.5 parts (per 100,000) fluorine, whereas the water supplies for the otn section...
متن کاملKINETICS OF -Fe NANOCRYSTALLIZATION IN Fe55Cr18Mo7B16C4 BULK AMORPHOUS ALLOY
Abstract: In this research work, crystallization kinetics of Fe55Cr18Mo7B16C4 alloy was evaluated by X-ray diffraction, TEM observations and differential scanning calorimetric tests. In practice, crystallization and growth mechanisms were investigated using DSC tests in four different heating rates. Results showed that a two -step crystallization process occurred in the alloy in which - Fe phas...
متن کاملNANOCRYSTALLIZATION MECHANISMS OF Fe52Cr18Mo7B16C4Nb3 BULK AMORPHOUS STEEL
Crystallization kinetics of Fe52Cr18Mo7B16C4Nb3 alloy was evaluated using X-ray diffraction, differential scanning calorimetric (DSC) tests and TEM observations in this research work. In effect, crystallization and growth mechanisms were investigated using DSC tests in four different heating rates (10, 20, 30, 40 K/min) and kinetic models (i.e. Kissinger- Starink, Ozawa, and Matusita methods). ...
متن کاملStudies in Endemic Fluorosis: Visakhapatnam and Suburban Areas: Distribution of Fluorine in Local Waters
Raghavachari and Venkataraman (1940) King Institute, Guindy, reported the occurrence of fluorides in waters from the Visakhapatnam District. Further particulars sought from the King Institute indicated: "In connection with the investigation of rural water supplies, a large number of samples from bore wells and dug wells in the Visakhapatnam District were analysed; 11 sources yielded water conta...
متن کاملIs Dental Fluorosis Caused by Thyroid Hormone Disturbances?
Although it has been known since 1917 that mottled dental enamel (later recognized as dental fluorosis—DF) is identical with that observed in thyroid dysfunction, disturbances of thyroid hormone metabolism during crucial periods of tooth development as the primary cause of DF have received very little consideration by dental researchers. New findings indicate that thyroid hormone metabolism is ...
