POLYTETRAFLUOROETYLENE TAPE AS TEMPORARY RESTORATIVE MATERIAL: A FLUID FILTRATION STUDY

Abstract

Purpose: The purpose of this study was to

compare the sealing ability of temporary

restorative materials at 24 hrs and 1 week.

Materials and Methods: Endodontic access cavities

were prepared in 56 extracted lower incisor-teeth

and divided into 5 groups (n=10). Standard 5 mm

deep access preparations were completed and root

canals were prepared to size ISO #30 file. The access

cavities were restored as follows: Group 1: temporary

restorative material (Ceivitron); Group 2: glass ionomer

cement (Fuji II); Group 3: zinc oxide-eugenol cement

(IRM); Group 4: zinc phosphate cement (Adhesor);

Group 5: polytetrafluoroetylene tape (PTFE). The

quality of the coronal sealing of each specimen was

measured (24 hrs and 1 week) using fluid transport

model. The data was analysed with repeated

measurements of ANO VA, Tukey, Paired samples T-Tests.

Results: A significant difference was found among

the groups at all time-periods (p<0.05). At 24 hrs,

PTFE showed similar leakage with Ceivitron, IRM,

and Fuji II but it showed higher leakage than Adhesor.

At 1 week, Ceivitron showed higher leakage than

PTFE, meanwhile PTFE showed similar leakage

with IRM, Fuji II, and Adhesor (p>0.05). Sealing

ability of IRM and PTFE groups significantly

increased by time (p<0.05 and p<0.001 respectively).

Conclusion: Within the limitations of this study, PTFE

showed an acceptable short-term sealing capability

when compared to the other commonly used temporary

restorative materials at 1 week measurements.
