Microbial contamination comparison between cotton pellet and polytetrafluoroethylene tape endodontic spacers: a systematic review

Abstract

This systematic review compares polytetrafluoroethylene tape and cotton pellet when used as endodontic spacers underneath provisional restorations. The review followed the PRISMA guidelines and was registered in the PROSPERO database (CRD42020176555). Studies that compared the microbial contamination between polytetrafluoroethylene tape and cotton pellet, when used as spacers, were included. Literature searches of Pubmed, Embase, EBSCOHost Dentistry & Oral Sciences Source, Scopus, and Open Grey databases were conducted from their inception until May 2020 for studies in English or other Latin script languages. Hand searching of reference lists was performed. Three laboratory and three clinical studies were included. The risk of bias of the component studies varied widely. Results from the laboratory studies showed higher bacterial counts for cotton pellets. Results from the clinical studies showed that polytetrafluoroethylene tape was associated with a significantly lower incidence of microbial contamination. Findings were consistent throughout the studies, though the evidence available is scarce and heterogeneous. Polytetrafluoroethylene tape was associated with less microbial contamination when compared with cotton pellets as endodontic spacers and therefore appears to be a more suitable material for the purpose.

Undergraduate Endodontic Training and Its Relation to Contemporary Practice: Multicenter Cross-Sectional Study in Saudi Arabia

“…A recent survey found that the majority of dentists in Saudi Arabia use the same temporization techniques taught in dental schools [ 58 ]. Teflon spacers were found to be a better alternative to cotton pellets [ 59 , 60 ]. However, cavit restoration is only used for less than two weeks and deteriorates easily under masticatory forces [ 56 , 57 , 61 ].…”

The Effect of Calcium Hydroxide, Triple Antibiotic Paste and Chlorhexidine on Pain in Teeth with Symptomatic Apical Periodontitis: A Randomised Controlled Trial

“…Firstly, in the present study, cotton pellets were used as endodontic spacers and to wipe off excess medicaments from the access cavity walls. This step might leave residual cotton fibres on the access cavity walls, and can interrupt the seal of the temporary restoration as well as acting as a potential substrate for surviving bacteria [ 34 ]. Secondly, the procedures were performed without the aid of an endodontic microscope.…”
