ABSTRACT
Objective:
To observe the structure and formation of plaque.Methods:
A 1 mm in heigth and 3 mm in diameter plastic ring was adhered to enamel slice, then the enamel slices with plastic rings were adhered to right maxillary first molars in order to establish the model of dental plaque.The specimens of dental plaque for 1 day, 5 days and 9 days were serially sectioned and were imaged by TEM.Results:
The TEM results showed that there were few microorganisms in early plaques, mainly of which were coccus. With the time went on, the kind and quantity of the microorganisms became more, and bacilli and hyphomycetes also appeared. In mature plaques, there were fence-like structure with coccus in center and bacilli and hyphomyceters at both sides, in which some bacteria went to necrosis.Conclusion:
The ultrasrtucture of this dental plaque model was similar to nature's with a certain extent values.
