Резюме
All academic tutors in the preclinical and clinical teaching are facing
the problem with non accurate cavity preparations. The mistakes are related not
only to dental amalgam restorations but to aesthetic restorations and endodontic
cavities too. The aim of the present study was to measure the proper actual sizes
of the clinical crown of molars and their variability in favour of more accurate cavity
preparation in cariology and endodontics. 313 molar teeth are included in the study
and following lengths were measured: mesiodistal, buccolingual, and buccal crown
hight. The differences with commonly used in Bulgaria local literature sources are
signifi cant. It can be useful for the practice some of the regular terminology in lectures
and operative dentistry manuals to be reconsidered. Cavities with buccolingual
size up to 1/3, convergence of cavity walls in cariology, and even the possibility
of convergence in endodontic cavities is essential to be carefully revisied. Respecting
the decreasing of the sizes of the crowns of human molars during evolution, due
to modern food industry, will lead to better clinical decisions in favour of the most
important treatment task: rare restoration replacement, lower ware rates, and lower
rates of secondary caries.
