Minimally invasive access cavities in endodontics

Background: The access cavity is a critical stage in root canal therapy and it may influence the subsequent steps of treatment. new minimally invasive endodontic preparation concept aims to preserve sound tooth structure by conserving as much intact dentine possible including pulp chamber's roof, keep teeth from fracturing during after While there great interest such opening designs numerous publications, still lack scientific evidence support application modern clinical practice. This review critically examine literature on minimal preparations, explain effect various aspects treatment, identify areas where additional research required. Data: An electronic search for English-language articles was performed using following databases: Google Scholar, PubMed, Research Gate. keywords were used: "minimally cavity", "conservative ", "classification cavity". Study selection: 64 papers that most relevant topics this selected between 1969 26 February 2022. Conclusions: Minimally cavities can be classified into conservative, ultraconservative, truss access, caries restorative-driven cavities. There deficiency proof maintains resistance fracture endodontically treated greater than traditional no difference percentage untouched walls debris removal with conservative vs cavities, however, ultraconservative resulted poor irrigation efficacy compared ones. Also, lower cyclic fatigue rotary instruments obturation voids associated studies about have wide range methodological disadvantages or register unsatisfactory inconclusive results. Therefore, further topic needed especially everyday advancement techniques armamentarium used endodontics.
