Properties of obturations and obturation materials, associated with the development of secondary caries

Silviya Dimitrova, Nadia Bibova


The main part of dentists` work is associated with the operative treatment of dental caries, aiming at the sta­bilization of the process and restoration of the natural anatomy and function of the teeth with artificial ma­terials. With the emergence of restorative dental medicine came the questions related to the survival rate of the restorations, the reasons for their replacement and the possibilities for control and management of the factors, leading to activation and progression of the carious process.

The aim of the literature overview is to study the most common reasons, leading to a decrease of the surviv­al rate of different restorations within the conditions of the mouth cavity. It analyzes factors with direct and indirect importance for the development of secondary caries and the longevity of obturations, such as po­lymerization shrinkage, accumulation of dental biofilm, micropermeability, marginal adaptation, micro­gap, etc.
