HYGIENE TRIBUNE | March 2010 f HT page 1B clear bands or the traditional metal brackets. Teens and children like the idea of having a choice and creating their own personal style. Brackets come in gold, ceramic and stainless steel. There are various types of appliances that are also used with traditional orthodontics. Head gear is used on patients with an overbite. The headgear gently restricts forward growth of the maxillary teeth. The Herbst Appliance is used on younger, growing patients and reduces the overbite by encouraging the lower jaw forward and the maxillary molars backward. The palatal expander puts gentle pressure on the maxillary molars and expands the palate. Positioners are clear, plastic appliances that complete traditional orthodontics and are an interim treatment between braces and a retainer. Retainers can be fixed or removable and hold the teeth in position when orthodontics has been completed. Seperators are small rubber bands that are placed before braces to space the teeth and ready them for brackets. for preventative care. Orthodontic patients are at a very high risk for demineralization, the dreaded white spots. White-spot lesions are the earliest microscopic evidence of enamel caries. Once saliva pH reaches 5.5 or lower, acid begins to dissolve the enamel. Teens are one of the main age groups in braces and one of the main groups to use sports drinks and sodas. These beverages have a pH almost as low as battery acid: their pH is about 2.3 and battery acid is 1.0. There are many types of remineralization products. MI Paste or MI Paste Plus, available through GC America, combines amorphous calcium phosphate (ACP) and casein phosphopeptide-amorphous calcium phosphate CPP-ACP, also known as Recaldent™. Tricalcium phosphate, TCP, is available in Clinpro 5000. Calcium sodium phospho-silicate is also available in many professional and overthe-counter products. Fluoride and remineralization products should be used in combination in orthodontic patients to prevent white spot lesions. Xylitol is another necessity for orthodontic patients. Xylitol reduces the bacteria that cause caries. Xlear manufactures the Spry Dental Defense System® that contains an oral rinse, toothpaste, oral mist, mints and gum. Clinical A final word Orthodontic patients face challenges in home care and maintaining gingival health. Electric toothbrushes, such as Sonicare by Phillips and Oral-B by Braun, are excellent products that make for easier and more effective homecare for the orthodontic patient. Water-pik by Teledyne and the in-shower H20 irrigator are both very useful home care tools as well. Adults, teens, children and parents need to understand periodontal disease and the destructive effect of periodontal bacteria. OralDNA manufactures a saliva test, MyPerioPath, that determines the patient’s periodontal bacteria. The dentist and hygienist can then recommend antibiotic therapy to reduce these bacteria. Remember, orthodontic patients have invested heavily in their mouths and they want a pretty smile after treatment. We owe it to our patients to explain, educate and motivate about technologies, treatments and products that will make their orthodontic treatment a success. Of course, it goes without saying that hygienists need to do a thorough periodontal examination on all patients. Technologies like the DentalR.A.T. 2.0., developed by hygienist Becky Logue, make periodontal charting easier by incorporating a foot pedal that can be used while doing 3B computerized periodontal charting.
