Figure 2. Classification LOV/DD (measurements)
We propose to write it in the form of a fraction, where the numerator
indicates the location of defects - LOV, and the denominator indicates
the depth of decay - DD. For example: 1/0, 1/1, 1/2, 1/3, 1/4, 2/0, etc.
For all types of cavities localized in the cervical margin of a tooth,
we used the classification being previously described by us, where the
numerator indicated the level of the cervical location of the cavity. To
describe the depth of the location of the cavity margin line towards the
gingival level, we used the index, the value of which was equal to the
distance (expressed as an integer in millimeters) from the level of the
epithelial attachment to the deepest point of the cavity margin line. If
the bottom of the cavity was located supragingivally, we put the “+”
sign in front of the index; if the bottom of the cavity was located
subdingivally, we put the “-” sign in front of the index; if the
bottom of the cavity was located at the level of the epithelial
attachment, we used the “ index.11
If the cavity had marginal decay of two or more sides - we chose the
deepest cavity for our classification. For example:
2+1 /3, 30/4 etc.
According to our research, we proposed an algorithm for choosing a
method dental treatment, based on the classification we proposed (Table
1).
