Questions to Cover With Dental Hygienist Schools<\/strong><\/h3>\nNow that you have decided to become a dental hygienist in Crucible PA, you can begin the process of comparing programs and schools. As we discussed at the start of this article, many prospective students start by looking at the location and the cost of the colleges. Maybe they search for several online options as well. Even though these may be relevant initial points to consider, there are a few additional questions that you need to address to the schools you are reviewing in order to make an informed decision. Toward that end, we have supplied a list of questions to help you with your due diligence and ultimate selection of the best dental hygienist college for you.<\/p>\n
Is the Dental Program Accredited?<\/strong> There are several good reasons why you should only choose an accredited dental hygienist college. If you are intending to become licensed or certified, then accreditation is a condition in virtually all states. In order to take the National Board Dental Hygiene Exam, your dental school must be accredited by the Commission on Dental Accreditation (CDA). Accreditation also helps guarantee that the education you receive is comprehensive and of the highest quality. Crucible PA employers typically prefer or require that new hires are graduates of accredited programs. And finally, if you are applying for a student loan or financial aid, usually they are not offered for non-accredited programs.<\/p>\nIs Adequate Practical Training Provided?<\/strong> Practical or clinical training is an important portion of any dental training program. This applies for the online college options as well. A number of dental hygienist colleges have relationships with local dental offices and clinics that furnish practical training for their students. It’s not only imperative that the school you select provides enough clinical hours but also provides them in the kind of practice that you ultimately would like to work in. For example, if you are interested in a career in pediatric dentistry, make sure that the school you enroll in offers clinical rotation in a local Crucible PA dental office that focuses on dental treatment for children.<\/p>\nAre Internships Available?<\/strong> Find out if the dental schools you are looking at sponsor an internship program. Internships are probably the most effective means to obtain hands-on, clinical experience in a professional dental practice. They make it easier for students to transition from the theoretical to the practical. They can also help students create working relationships in the professional dental community. And they look good on resumes too.<\/p>\nIs Job Placement Support Offered?<\/strong> Many students that have graduated from dental hygienist schools require help obtaining their first job. Check if the programs you are researching have job assistance programs, and what their job placement rates are. Schools with higher job placement rates are likely to have good reputations within the Crucible PA dental community in addition to extensive networks of contacts where they can place their students for internships or employment.<\/p>\nAre the Classrooms Smaller?<\/strong> Check with the colleges you are looking at how large typically their classes are. The smaller classes generally provide a more intimate environment for learning where students have increased access to the teachers. Conversely, large classes often are impersonal and provide little individualized instruction. If practical, ask if you can sit in on a couple of classes at the Crucible PA dental hygienist school that you are leaning toward in order to witness first hand the degree of interaction between students and teachers before making a commitment.<\/p>\n <\/strong>What is the Total Expense of the Program?<\/strong> Dental hygiene colleges can fluctuate in cost dependent on the duration of the program and the amount of practical training provided. Other variables, for example the reputations of the schools and whether they are private or public also come into play. But along with the tuition there are other significant expenses which can add up. They can include costs for such things as commuting and textbooks as well as school equipment, materials and supplies. So when examining the cost of colleges, remember to include all of the expenses associated with your education. The majority of schools have financial aid departments, so make sure to ask what is available as far as loans, grants and scholarships in the Crucible PA area.<\/p>\nAre the Classes Convenient?<\/strong> Before enrolling in a dental hygienist school, you need to verify that the assistant or hygienist program furnishes classes that fit your schedule. This is particularly true if you will be working while getting your education and must go to classes near Crucible PA at nights or on weekends. And even if you choose an online school, you will still have to schedule your practical training classes. Also, while making your inquiries, ask what the make-up practice is if you should have to miss any classes due to illness, work or family emergencies.<\/p>\nAttending Dental Hygienist School near Crucible PA?<\/h3>\nCrucible steel<\/h3>
Crucible steel is steel made by melting pig iron (cast iron), iron, and sometimes steel, often along with sand, glass, ashes, and other fluxes, in a crucible. In ancient times steel and iron were impossible to melt using charcoal or coal fires, which could not produce temperatures high enough. However, pig iron, having a higher carbon content thus a lower melting point, could be melted, and by soaking wrought iron or steel in the liquid pig-iron for long periods of time, the carbon content of the pig iron could be reduced as it slowly diffused into the iron. Crucible steel of this type was produced in South and Central Asia during the medieval era. This generally produced a very hard steel, but also a composite steel that was inhomogeneous, consisting of a very high-carbon steel (formerly the pig-iron) and a lower-carbon steel (formerly the wrought iron). This often resulted in an intricate pattern when the steel was forged, filed or polished, with possibly the most well-known examples coming from the wootz steel used in Damascus swords. Due to the use of fluxes the steel was often much higher in quality (lacking impurities) and in carbon content compared to other methods of steel production of the time.<\/p>
Techniques for production of high quality steel were developed by Benjamin Huntsman in England in the 18th century. Huntsman used coke rather than coal or charcoal, achieving temperatures high enough to melt steel and dissolve iron. Huntsman's process differed from some of the wootz processes in that it took a longer time to melt the steel and to cool it down and allowed more time for the diffusion of carbon.[1] Huntsman's process used iron and steel as raw materials, in the form of blister steel, rather than direct conversion from cast iron as in puddling or the later Bessemer process. The ability to fully melt the steel removed any inhomogeneities in the steel, allowing the carbon to dissolve evenly into the liquid steel and negating the prior need for extensive blacksmithing in an attempt to achieve the same result. Similarly, it allowed steel to simply be poured into molds, or cast, for the first time. The homogeneous crystal structure of this cast steel improved its strength and hardness compared to preceding forms of steel. The use of fluxes allowed nearly complete extraction of impurities from the liquid, which could then simply float to the top for removal. This produced the first steel of modern quality, providing a means of efficiently changing excess wrought iron into useful steel. Huntsman's process greatly increased the European output of quality steel suitable for use in items like knives, tools, and machinery, helping to pave the way for the Industrial revolution.<\/p>
Iron alloys are most broadly divided by their carbon content: cast iron has 2-4% carbon impurities; wrought iron oxidizes away most of its carbon, to less than 0.1%. The much more valuable steel has a delicately intermediate carbon fraction, and its material properties range according to the carbon percentage: high carbon steel is stronger but more brittle than low carbon steel. Crucible steel sequesters the raw input materials from the heat source, allowing precise control of carburization (raising) or oxidation (lowering carbon content). Fluxes, such as limestone, could be added to the crucible to remove or promote sulfur, silicon, and other impurities, further altering its material qualities.<\/p>
Various methods were used to produce crucible steel. According to Islamic texts such as al-Tarsusi and Abu Rayhan Biruni, three methods are described for indirect production of steel.[2] The medieval Islamic historian Abu Rayhan Biruni (c. 973\u20131050) provides the earliest reference of the production of Damascus steel.[3] The first, and the most common, traditional method is solid state carburization of wrought iron. This is a diffusion process in which wrought iron is packed in crucibles or a hearth with charcoal, then heated to promote diffusion of carbon into the iron to produce steel.[4] Carburization is the basis for the wootz process of steel. The second method is the decarburization of cast iron by removing carbon from the cast iron.[3] The third method uses wrought iron and cast iron. In this process, wrought iron and cast iron may be heated together in a crucible to produce steel by fusion.[4] In regard to this method Abu Rayhan Biruni states: \"this was the method used in Hearth\". It is proposed that the Indian method refers to Wootz carburization method;[3] i.e., the Mysore or Tamil processes.[5]<\/p><\/div>\n
