Evaluation of Cotton and Polytetrafluoroethylene Tape as Endodontic Spacer martial in pulpectomy of primary molars

Abstract

Aim: This study aimed to evaluate the sealing ability of cotton and Polytetrafluoroethylene (PTFE) tape as spacer under temporary filling material in between root canal treatment visits.Method and Materials: forty infected primary molars indicated for pulpectomy from twenty children were selected for this study. Two visits root canal treatment were done with temporary restorative material and application of the tested cotton and PTFE as a spacers on each side randomly. Microbiological study was done after pulpectomy by taking sample from the coronal portion of the cavity at the folloing steps, directly after pulpectomy, seven days follow up for both the cavity and the spacer material itself.Results: Cotton fibers group showed bacterial contamination for both the cavity and material itself while PTFE showed the least amount of bacterial growth over their samples. There was contamination of the majority of cotton group samples in contrary to minimal amount for PTFE samples showed bacterial contamination. Conclusions:Using PTFE as a spacer material under provisional restoration showed very good results from microbial point of view and it may be used as cotton alternative in the future in the endodontic field

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

“…Six articles were selected for full-text retrieval. Three laboratory studies ( 6 , 9 , 15 ) and three clinical studies ( 7 , 16 , 17 ) fulfilled the inclusion criteria and were included in the review. Due to heterogeneity among the included studies, quantitative synthesis was not performed…”

“…The period of evaluation ranged from 1 to 4 weeks. Two studies used primary teeth ( 16 , 17 ). All studies described a rationale for the period of evaluation.…”

“…All studies described a rationale for the period of evaluation. One was based on recommendations for intracanal medicament efficacy, ( 7 ) whereas the remaining two were based on previous recommendations for provisional restorative materials ( 16 , 17 ). All three studies used colony-forming unit counts as their outcome measure ( 7 , 16 , 17 ).…”

“…One study was deemed to have a ‘moderate’ risk of bias arising from differences between groups at baseline, lack of true randomization and appropriate statistical analyses, and limitations in trial design ( 6 ). Of the three clinical studies, all studies were deemed to have an overall ‘high risk’ of bias, arising from lack of detail regarding their randomization process and allocation concealment ( 7 , 16 , 17 ). The corresponding authors of four studies ( 7 , 15 - 17 ) were contacted for clarifications necessary to the assessment of risk of bias, with no replies.…”
