Diet has an influence in our oral health as well.  Most of us have been warned against eating too much candy because it will give us cavities. This is true because much of the bacteria in our mouths are nourished by simple sugars and carbohydrates.  An excess of candy, soda, or other simple sugars is an easy way to let bacteria thrive in our mouths. In addition, there are other ways to further reduce the risk of invaders harming the mouths’ health. Visits to the dentist can be beneficial where fluoride treatments are available. Combined with dental sealants , these treatments can, in most cases, ensure prevention of harmful bacterial effects.  Fluoride is extremely effective in protecting enamel on the teeth. “Fluoride, a chemical that appears naturally in groundwater in many areas of the world, quickly bonds with the tooth's enamel to maintain its smooth crystalline surface and deter bacteria from gaining a toehold.”  The Oral-B website advises people to “drink tap water when possible” because “if bottled water is your main source of drinking water, you could be missing the decay-preventative benefits of fluoride.”  Also, a study in the Journal of the American Dental Association states that “antiseptic mouthwashes have been associated with a 28 to 34 percent reduction in dental plaque biofilms at six month follow-ups. Chlorhexidine gluconate [mouthwash] rinses, when combined with toothbrushing, have been reported to reduce oral biofilms . . by 50 to 55 percent.”  By going to the dentist and following advice, one can begin to prevent oral infection and disease.
Test of Written Spelling Fourth Edition (TWS-4) - Is a norm-referenced test of spelling administered using a dictated word format. The TWS-4 now has two alternate or equivalent forms (A and B) which make it more useful in test-teach-test situations. The TWS-4 is appropriate for students in Grades 1 through 12 as well as for those in remedial programs. The TWS was developed after a review of 2,000 spelling rules. The words to be spelled are drawn from 10 basal spelling programs and popular graded word lists. The results of the TWS-4 may be used for four specific purposes: to identify students whose scores are significantly below those of their peers and who might need interventions designed to improve spelling proficiency, to determine areas of relative strength and weakness in spelling, to document overall progress in spelling as a consequence of intervention programs, and to serve as a measure for research efforts designed to investigate spelling. Can be administered in 20 minutes to either groups or individuals and yields the following educationally relevant information: standard scores, percentiles, spelling ages, and grade equivalents.
