Abstract

The development of the cavity configuration factor was substantiated by the necessity of quantifying the ratio of polymerization shrinkage and polymerization stress indicators in accordance with the peculiarities of the geometry of prepared carious defect. However, according to various studies, the level of distribution of polymerization stress more strongly depends on the absolute sizes of the investigated restoration samples, and not directly on the C-factor, however, it has not been adequately evidently interpreted from the point of view of the clinical significance for the obtained results.

The aim of the study. To analyze the effect of the configuration factor of the prepared cavity on the success of the direct restorations function in the process of developing a model of predictive assessment of stress distribution at the interface of composite material and tooth tissues.

Materials and methods. Google Scholar search form (http://scholar.google.com) was used with its advanced features for realization of study objective. The following sets of words «C-factor», «dental cavity configuration», «cavity geometry», «direct restoration», and «composite restoration» were used as header operators in various combinations, each resulting for the search of keywords combination represented as a set of academic papers on relevant topics, that were subsequently subject to content analysis.

Results and discussion. Based on the literature data, the reduction of shrinkage stress was confirmed with the growth of the quantitative index of the C-factor and a decrease in the predictive index of the success of composite restoration represeted the similar trend. The C-factor in the range of 0,3-2,3 is not extremely critical in terms of the risk of microleakage formation between the composite and the tooth, as compared to indicators of the C-factor approaching 3,0.

Conclusions. The further development of a complex model of finite elements with the representation in its structure elements of a different density (in particular, enamels, dentin, various composites) and the corresponding mathematical argumentation of the polymerization shrinkage and stress vectors, will allow to objectivize the cumulative effect of the C-factor on the success of the composite restoration function, proceeding from the poly-directional stresses at the bonding interface of the composite material and tooth tissues interface.
