Morphological Comparison of Bacillus-Shaped Deposits Constructed with Whitlockite Crystals among Human Supragingival, Marginal, and Deep Subgingival Calculi

抄録

We have reported that some filamentous and rod-shaped microorganisms in human dental calculus were replaced by the hexahedrally based crystals of whitlockite. Morphologically, such rocky pile-shaped deposits in subgingival, marginal (ledge-type), and deep subgingival (spiny) calculi were more or less distinguishable. This may be caused by the differences of the microbial flora, and the supplied Mg content and pH range derived from either saliva or gingival fluid
