Study on ptfe tape as root canal isolation material in oral cavity

PTFE tape, which is commonly used as plumber’s tape is an inorganic, non-fibrous, ribbon like material. The aim of this study was to evaluate PTFE tape as endodontic spacer material and to compare it with commonly used spacer material that is cotton, in primary teeth.;Seventeen children undergoing pulpectomy of lower second primary molar bilaterally were included in the study. 

Cotton and PTFE tape were placed as spacers on each side randomly. Samples were taken from the access cavity at baseline and after seven days to check for microbial leakage. Spacer materials were also checked for microbial contamination.;The results revealed that there was a significant increase in the bacterial colony count after seven days in cotton group. The access cavities were also positive for microbial leakage in the cotton group where the spacers showed positive growth. In PTFE group only two samples showed microbial contamination of spacer and out of two only one sample showed contamination of access cavity along with spacer.;Within the limitations of this study, it can be concluded that PTFE tape performed better than cotton as endodontic spacer material. 

Thus, PTFE tape can be recommended as an endodontic spacer material as an alternative to cotton in primary teeth.
