Abstract
Objective: In this study, oral micro-organisms have been examined in saliva according to morphological type by ages through use of a phase-contrast microscope.
Materials and Method : 177 subjects participated in this study. The samples were collected from the saliva on the lingual side of the lower frontal tooth. The amount and motile were checked under the classification of such types as oral micro-organisms as cocci, bacilli, filament, comma or spiral, respectively.
Results: The amount of oral micro-organisms in saliva was less than in dental plaque at the inter-proximal area. The amount of cocci and bacilli type oral micro-organisms were revealed in a decreasing tendency from an infant to a child, increasing rapidly in adolescent age and decreasing gradually as age increased. The motile of cocci and bacilli typed oral micro-organisms decreased a little but were steady in low levels with the increase in age. The amount and the motile of filamentous type or spiral type oral micro-organisms in saliva were found to be very little and inactive, at all ages. In order to decrease the activity of oral micro-organisms saliva for the prevention of oral diseases, such trials as increasing the salivary flow, cleansing the oral cavity and the dilution of the saliva by frequent intake of water or proper mouth gargling, was recommended, even though it revealed less saliva found than in other oral areas.
Conclusion: It was concluded that it could be hard to be applied the oral micro-organism factors in saliva as one of the important items to estimate for individual oral health state index because of no distinct differences on the amounts and the motile of each type of oral micro-organism, between the age groups.
