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.
