Introduction. A significant loss of dental structures during endodontic treatment increases the probability of tooth cracks, fractures or even tooth loss. The aim of this systematic review is to assess the influence of temporary filling material on dental cracks and fractures during endodontic treatment. Materials and methods. The literature was digitally searched for in vivo and in vitro studies using Pubmed, ScienceDirect, Willey Online Library databases. An additional hand search was performed. Due to lack of data search was not limited with the start period and was completed 27th of March, 2018. A total of 38 (after duplicate removal) potentially relevant records were identified in the literature search. After screening, full-text analysis of selected studies was done. Studies quality was estimated using Checklist for Reporting In vitro Studies and methodology applied. Extracted data was structured and summarized. Results. 5 publications met the selection criteria. 10 temporary filling materials were evaluated in this review. Non-eugenol chemically hardening temporary filling materials were tested in all studies. The analysis demonstrated that these temporary filling materials significantly increase the filling and dental fractures. Also, have the lowest fracture and tooth fracture resistance. Glass ionomer cements (GIC) presented the higher hermetic, tightness and fracture resistance features, which equates to the fracture resistance of natural teeth. Conclusions. Temporary filling material influences dental cracks and fractures during endodontic treatment. The highest effect in dental cracks and fractures had ready-to-use, non-eugenol containing temporary filling materials, the lowest - GIC. Clinical significance. In vitro studies form a pivotal role in dental research contribution to a substantial evidence base and is an integral part of the decision-making process in clinical practice. In order to improve the treatment quality of the tooth and its long survival during endodontic treatment, understanding the effect of temporary filling material on teeth cracks and fractures is significant. Priority should be given for temporary filling materials which are stronger and with better bonding to dental structures. |
