Abstract

AIM AND OBJECTIVE

This study was conducted to microbiologically evaluate cotton, PTFE tape, and foam pellets as endodontic spacer in primary teeth.

MATERIALS AND METHODS

Thirty primary second molars indicated for pulpectomy were included in this study. Followed by the completion of pulpectomy in each teeth cotton, PTFE tape, and foam pellets were placed as endodontic spacers randomly in 10 teeth each. The samples were collected from the pulp chamber at baseline and after 7 days to evaluate for microbial contamination of the same. The data obtained was tabulated and subjected to appropriate statistical analysis.

RESULTS

There was a statistically significant increase in the colony forming unit after 7 days in cotton and foam pellet group. But PTFE tape group showed very minimal contamination of the pulp chamber after 7 days.

CONCLUSION

Within the limitations of this study, it can be concluded that PTFE tape found to be the best alternative to cotton as an endodontic spacer.

CLINICAL SIGNIFICANCE

In case of multiple visit pulpectomy procedure, the state of sterility must be maintained in between the appointments until a definitive coronal restoration is placed following root-canal obturation. So it is mandatory to place an endodontic spacer under a provisional restoration to maintain the patency of the root canals and prevention of the microbial growth. The PTFE tape is inorganic, nonfibrous material which can be tightly packed without any voids under the provisional restoration. So PTFE tape is the best material to maintain the root canal patency and to provide a sterile environment by preventing the microbial growth under the provisional restoration as an endodontic spacer material in between the appointments.

摘要

目的

本研究旨在对棉花、聚四氟乙烯带和泡沫颗粒作为乳牙牙髓腔充填物进行微生物学评估。

材料与方法

本研究纳入30颗需进行牙髓摘除术的乳牙第二磨牙。在每颗牙齿完成牙髓摘除术后，将棉花、聚四氟乙烯带和泡沫颗粒作为牙髓腔充填物随机分别放置于10颗牙齿中。在基线期和7天后从髓腔采集样本，以评估其微生物污染情况。将获得的数据制成表格并进行适当的统计分析。

结果

7天后，棉花和泡沫颗粒组的菌落形成单位有统计学意义的增加。但聚四氟乙烯带组在7天后髓腔污染极少。

结论

在本研究的局限性范围内，可以得出结论，聚四氟乙烯带被发现是作为牙髓腔充填物替代棉花的最佳选择。

临床意义

在多次就诊的牙髓摘除术过程中，在根管充填后放置最终的冠修复体之前，每次就诊之间必须保持无菌状态。因此，必须在临时修复体下放置牙髓腔充填物以保持根管通畅并防止微生物生长。聚四氟乙烯带是一种无机、非纤维材料，可以在临时修复体下紧密填充而无任何空隙。因此，聚四氟乙烯带是在就诊间隔期间作为牙髓腔充填物材料保持根管通畅并通过防止临时修复体下微生物生长来提供无菌环境的最佳材料。
