Microbial microleakage in temporary restorative materials after post space preparation
Keywords:Coronal leakage, bacterial leakage, temporary restorations, post, calcium hydroxide
AbstractPurpose: This study investigated the microbial microleakage through temporary restorative materials (Coltosol, IRM, Vidrion R) after post space preparation. Methods: Forty-two maxillary anterior human teeth were prepared and obturated with guttapercha and Sealapex using the lateral condensation technique, with 4mm of apical obturation remaining. Calcium hydroxide paste was used to fill the post space preparation, and 4mm of the coronal portion was restored with the temporary filling materials. Six specimens were totally sealed (negative control) and six specimens were not filled (positive control). An in vitro microbial leakage test (MLT) with a split chamber (upper/lower chambers) was used. Microbial microleakage was observed daily for 90 days. Data were analyzed by Kruskal-Wallis and Mann-Whitney tests. Results: Coltosol, IRM, and Vidrion R allowed microbial microleakage after 19 to 89 days. Conclusion: All temporary fillings and intracanal dressings did not prevent the penetration of microorganisms to the root apex. Key words: Coronal leakage; bacterial leakage; temporary restorations; post; calcium hydroxide
