In our result, plaque recovered from the UVHT samples showed the lowest counts for both nonmutans streptococci and total facultative bacteria counts whereas NC samples showed the highest counts, although the differences were not significant and the real antimicrobial effect of UV treatment could not be confirmed in an oral environment
. These findings, however, are in accordance with the in vitro study by Gallarado-Moreno et al.
The experimental arrangement simulates approximately three years of use of the attachments in an oral environment
. This time frame was chosen as it represented areas on able period of clinical use before the attachment might need maintenance.
Among many factors that influence the oral environment
, some are age dependent; for example, an immunogenic ability may change complex interrelations between particular species of oral microbiota and host organism during ontogenesis in generally healthy persons.
This, of course in combination with brushing, flossing and rinsing, provide a healthy balance of the microbial community, because saliva also provides nourishment for microorganisms to survive in a commensal manner in the oral environment
. Along with swallowing, proteins in the saliva such as lysozyme, histatins, and defensins help to inhibit adhesion of bacteria to the surfaces of the oral structures, thereby inhibiting bacterial metabolism.

Many factors may influence corrosion in the oral environment
such as type of materials, pH, temperature, humidity, oxygen and type of
By the age of 15, the dietary habits of the individuals are more or less established and the permanent teeth have been exposed to the oral environment
for 3-9 years, thus making the assessment of caries prevalence even more meaningful at this age .
They include such subjects as topography in bio-tribocorrosion, wear-corrosion mechanisms in biomaterials, fretting corrosion processes and wear mechanisms in medical implants, wear and corrosion in the loosening of total joint replacements, abrasion-corrosion mechanisms of implant materials, wear prediction in dental composites, bio-tribocorrosion and the biological environment, biofilms in the oral environment
, protein adsorption of biomedical alloys, and several articles on bio-tribocorrosion in the clinical environment, including dental implants and joints.
"Our proprietary blend of natural, holistic ingredients promotes a healthy oral environment
, killing germs that cause bad breath and plaque," Herroon says.
Changes in the oral environment
during four stages of orthodontic treatment.
Their success depends largely on their colour stability as they undergo discoloration after prolonged exposure in oral environment
and therefore , need replacement for esthetic reasons.
