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.

Geçici Restoratif Dolgu Materyali Olarak Politetrafloroetilen Bant (Ptfe): Sıvı Filtrasyon Çalışması

Abstract

Amaç: Bu çalışmanın amacı, geçici restoratif materyallerin 24 saat ve 1 hafta süresinde sızdırmazlık kabiliyetlerinin karşılaştırılmasıdır. Gereç ve Yöntem: 56 adet çekilmiş alt çene kesici dişin endodontik giriş kaviteleri açıldı. Dişler 5 gruba ayrıldı (n=10). Giriş kaviteleri standart 5 mm derinlikte olacak şekilde açıldı ve kök kanalları ISO #30 numaraya kadar genişletildi. Giriş kaviteleri şu şekilde restore edildi: Grup 1: geçici restorasyon materyali (Ceivitron); Grup 2: cam iyonomer siman (Fuji II); Grup 3: çinko oksit öjenol siman (IRM); Grup 4: çinko fosfat siman (Adhesor); Grup 5: politetrafloroetilen bant (PTFE). Her örneğin koronal sızdırmazlık kalitesi sıvı filtrasyon yöntemi kullanılarak ölçüldü (24 saat ve 1 hafta). Veriler hesaplandı (Lp), tekrarlayan ölçümlerle ANOVA, Tukey ve bağımlı gruplarda P testi kullanılarak değerlendirildi. Bulgular: Tüm zamanlar için gruplar arasında anlamlı fark bulundu (p < 0.05). 24 saatte, PTFE; Ceivitron, IRM ve Fuji II ile benzer; fakat Adhesor den daha fazla sızıntı değeri gösterdi. 1 haftada; Ceivitron, PTFE den daha fazla sızıntı değeri gösterdi, aynı zamanda PTFE; IRM, Fuji II ve Adhesor ile benzer sızıntı değeri gösterdi (p > 0.05). IRM ve PTFE gruplarının sızıntı değeri zamanla önemli derecede azaldı (p < 0.05 ve p < 0.001 sırasıyla). Sonuç: Bu çalışmanın sınırları dâhilinde, PTFE, 1 haftalık ölçümlerde, diğer sıklıkla kullanılan geçici dolgu materyalleri ile kıyaslandığında, kabul edilebilir bir kısa-dönem sızdırmazlık kabiliyeti göstermiştir.
