*The tactics of treating such patients with cavities of 4/0 depend on
the etiology and depth of the change in the color of the tooth.
Currently, such teeth are treated by external or internal bleaching or
by less conventional methods: indirect restoration and artificial
crowns.
**The tactics of treating such patients with cavities of 4/4: use of a
fiber post is recommended.
In the available medical literature, we did not find any works devoted
to the questions of clear cavity classification. At the present stage of
the development of dentistry, the dynamic growth of new knowledge,
technologies and materials significantly changed the methods of treating
defects of dental hard tissues.12 In clinical cases
where the cavity is located subdingivally, the “Cervical Margin
Relocation” (CMR) can be used. During the period of dentistry
development, various CMR techniques have been developed and studied
gaining popularity among dental practitioners; however, there is no
clear classification of gingival cavities.3,13-16
The importance of dental restoration using fiber posts is being
discussed as well. After endodontic treatment of teeth, it is
recommended to use a fiber post, as there is a greater loss of dental
tissue, i.e. the decisive factor in choosing the method of treatment is
the amount of lost hard tissue. 3,17-20
In the SI/STA classification system, there is no clear distinction
between isolated carious cavities, located on one tooth surface, and
combined lesions that involve several surfaces. The disadvantage of this
classification is the characteristics of mainly chewing teeth, without
involving the anterior ones.3,15
The choice between direct and indirect restoration is complicated by the
fact that it does not depend on the objective factors. It depends on the
dentist’s knowledge, habits, preferences and stereotypes concerning the
treatment of such pathologies; the patient’s consent, financial
capabilities and other factors that have nothing to do with the methods
of evidence-based medicine, i.d. the absence of a cavity classification
formed a methodological gap in treatment of this pathology.
