Objective:
This study aimed to investigate the effectiveness of various commercial temporary restorative materials in preventing microleakage with a pre-endodontic sealing technique (PES).
Methods:
Ninety-six human single-rooted premolars were prepared for endodontic access and randomly allocated to five groups according to the material to restore the cavity (n=16): CON: Control group, Tetric N-bulk, Ivoclar; COL: Coltosol, Coltene; KET: Ketac Molar, 3M; FUJ: Gold Label Fuji II, GC; CLI: Clip F; and two experimental conditions (n=8): COT: conventional technique and, PES technique. Methylene blue dye penetration was measured in mm. Two-way ANOVA and Bonferroni post-hoc were used (p<0.05) Results: For most materials, PES exhibited statistically significantly lower values of dye penetration (p < 0.001), except for KET and COL. The highest dye penetration was found in FUJ using the COT technique.
Conclusion:
The PES technique was more effective in preventing microleakage when polymer-based materials were used. (EEJ-2025-02-027).

pre-mRNA Processing
Once about 20-40 ribonucleotides have been joined together by RNA polymerase, a group of enzymes adds a “cap” to the 5’ end of the growing transcript. In this process, a 5’ phosphate is replaced by modified guanosine that has a methyl group attached to it (7-Methyl...
