T wave. In general, T waves are in the same direction as the largest deflection of the QRS (normally the R wave). Negative in AVR Inverted T waves in precordial leads V1, V2, V3 can be seen in normal, young athletes Low T voltage changes may occur in the absence of any heart disease at all.
Skeletal Fluorosis: A âDiagnostic Riddleâ. One of the reasons doctors fail to detect skeletal fluorosis is because the symptoms and appearance of fluorosis can closely resemble other, more commonly known, bone and joint diseases. This is true for both the early and late stages of the disease. In the initial stages, known as âpre-skeletalâ fluorosis, a patient may suffer a variety of symptoms in the absence of any detectable bone changes, including joint pains, joint stiffness, and gastric distress. (Czerwinski 1988; Cook 1971).
In moderate to severe fluorosis, the cavity and decay rate is greatly increased. This means that your daughter will need many dental visits for fillings at a formative age and this must be done with great care as not to create a fearful patient later in adulthood. Fluorosis: What It Is and How to Prevent It. Any amount of fluoride can cause fluorosis. Fluorosis is a condition caused by too much fluoride during the years that a tooth develops inside the jawbone. It causes aesthetic and structural defects in the tooth. It can be caused by swallowing toothpaste with fluoride in it, consuming too much fluoride (via drinking water) or too many fluoride supplements (such as fluoride tablets) given by parents or pediatricians.
