Modes of Attachment to Tooth Surfaces
Tartar gives the surface of the teeth using several different modes, and attachments different mechanisms may even exist in the same calculus Deposit.
1. Investment film
a. Calculus can attach to the surface of the tooth by joining a film on the surface. The film is a thin, bacteria-free membrane that forms on the teeth during the late stage of the eruption.
B. This mode of attachment often occurs on the surface of the enamel.
c. Calculus deposits attach using film, usually easily removed, because this attachment on the film surface (and in fact not " tied " to the tooth surface).
2. Attachment to the irregularity of the surface of the tooth
a. The calculation may also be applied to surface irregularities of the teeth. These violations include cracks in the teeth, tiny holes on the left, where the periodontal ligament fibers untethered, and grooves in cemental surfaces, created as a result of faulty devices during the previous calculation of the removal procedure.
B. Full calculus removal in areas irregularities in the surface of the teeth, usually difficult, as these deposits can be placed in these defects of teeth.
3. Investments by direct contact of solid components and the tooth surface
a. The calculation may also be applied to the tooth surface by attaching directly to soda component of the tooth. In this mode the application of matrix calculus, safety Deposit box associated with inorganic crystals tooth.
B. Deposits are closely integrated with each other in the tooth surface, often hard to remove...
