| Popis: | The purpose of this article is to compare and contrast the different types of endodontic access cavity designs based on the current available evidence. Four types of access cavity designs, namely, traditional endodontic access cavity design (TEC), contracted/conservative endodontic access cavity design (CEC), ultra-conservative or ninja endodontic access cavity design (NEC) and truss endodontic access cavity design (TREC) have been suggested, and the latter three are currently in the limelight. Studies in vitro have been performed comparing the TECs, CECs, TRECs and NECs; except for the TECs, the other three types have not undergone clinical trials on patients. The choice of endodontic access cavity design affects fracture strength of the tooth, but remnants of pulpal tissue, due to ineffective instrumentation, can cause root canal treatment failure. CPD/Clinical Relevance: Root canal treatment with new access cavity designs has been proposed. However, there is lack of evidence to support such practices. It is important to consider the potential deleterious effects of such access cavity designs rather than emphasizing the preservation of tooth structure alone. |
