Teeth relationship

Bite-Registration Waxes are used to estabhsh the occlusion or horizontal relationship of the lower jaw to the upper jaw when there are opposing teeth present. Bite waxes may have a flow of 84% at 30°C. They are generally compounded from high-flow, low-melting paraffins, microcrystalline waxes, and resins. 

The mathematical relationship of the circular pitch to the pitch-circle circumference, number of teeth, and the pitch diameter is shown in the following equations ... 

The mathematical relationship of pitch diameter, diametric pitch, and number of teeth is shown in the equations below. As with any equation, one of the variables can be calculated if any two are known. 

More than 99% of total body calcium is found in bone the remaining less than 1% is in the ECF and ICE Calcium plays a critical role in the transmission of nerve impulses, skeletal muscle contraction, myocardial contractions, maintenance of normal cellular permeability, and the formation of bones and teeth. There is a reciprocal relationship between the serum calcium concentration (normally 8.6 to 10.2 mg/dL [2.15 to 2.55 mmol/L]) and the serum phosphate concentration that is regulated by a complex interaction between parathyroid hormone, vitamin D, and calcitonin. About one-half of the serum calcium is bound to plasma proteins the other half is free ionized calcium. Given that the serum calcium has significant protein binding, the serum calcium concentration must be corrected in patients who have low albumin concentrations (the major serum protein). The most commonly used formula adds 0.8 mg/dL (0.2 mmol/L) of calcium for each gram of albumin deficiency as follows ...

You might start out by saying A tooth is part of a mouth. That reveals a part-to-whole relationship. Then, check the answer pairs for a parallel relationship by substituting each pair in your sentence. An eyebrow is part of a face. That s true, so it s a possibility. A bark is part of a bite. No rule it out. An orthodontist is part of a dentist. A dentist could also be an orthodontist, but it s more likely that this answer was put in as a distracter because of its connection to teeth and mouths. Rule it out. A toothbrush is part of a holder. Again, it seems likely to be a distracter because of its relationship to teeth. Rule it out. A stalactite is part of a cave. A stalactite is a formation that hangs down from the ceiling of a cave, so the sentence is true and, therefore, a possibility. 

Radium has been shown to cause adverse health effects such as anemia, cataracts, fractured teeth, cancer and death. As shown in Tables 1-1 through 1-4, the relationship between the amount of radium that you are exposed to and the amount of time necessary to produce these effects is not known. Although there is some uncertainty as to how much exposure to radium increases your chances of developing a harmful health effect, the greater the total amount of your exposure to radium, the more likely you are to develop one of these diseases. More information on this subject is presented in Chapter 2. 

The relationship between fluoride and dental caries was first noted in the early part of the 20th century when it was observed that residents of certain areas of USA developed brown stains on their teeth. In the 1930s, it was observed that the prevalence and severity of this type of mottled enamel was directly related to high amounts of ingested fluoride [34],...

Oxygen isotopes of phosphate in seawater. Use of the oxygen isotopic composition of phosphate in biogenic hydroxyapatite (bones, teeth) as a paleotemperature and climate indicator was pioneered by Longinelli (1966), and has since been fairly widely and successfully applied (Kolodny et al., 1983 Shemesh et al., 1983 Luz et al., 1984). The relationship between phosphate oxygen isotopic fractionation and temperature originally proposed (Longinelli and Nuti, 1973) has been confirmed by later work (Blake et al., 1997 Colman, 2002).

This chapter describes how a traditional discussion of atomic structure and its relationship to organic chemistry is relevant to dentistry. Although the fundamental chemistry and biochemistry described here are common knowledge, the discussion centers on the associations with teeth and dental disease (Sects. 1 and 2). In addition, the difference between respiration and fermentation and the different types of fermentations involved in dental caries and periodontal disease are discussed (Sect. 3). The chapter concludes with a discussion of the difference between the outer cell surface of gram-positive and gramnegative bacteria that is important in causing these diseases (Sect. 4). 

Fig. 16.5 Relationship of DMFT and index of fluorosis to water fluoride content. The left y-axis indicates the number of decayed missing and filled teeth from caries (DMFT) and the right y-axis indicates the index of fluorosis, a measure of the deleterious effect of fluoride on the enamel surface (see text). The x-axis indicates the ppm fluoride found naturally in the drinking water supply. Triangles indicate DMFT and circles indicate the fluorosis index in the same populations. The curves showing the decrease in caries and decrease in fluorosis intersect at 1 ppm fluoride in the water supply on the x-axis (Copy of Fig. 3 from Hodge HC, Smith FA. (1954). Some public health aspects of water fluoridation. American Association of the Advancement of Science Publication No 19 Washington DC 1954 AAAS 1954, pp. 79-109)...
