| Background: Various surgical and non-surgical techniques have been proposed to restore the furcal defects, with non-surgical techniques being preferred due to their non-invasiveness, convenience, and fewer side effects. Several materials with different physical properties and treatment success rates have been used for this purpose. However, the efficacy of cold ceramic (CC) for furcal and root canal wall perforation repair in primary teeth has not been previously evaluated. Purpose: This study aimed to compare bacterial leakage and dye penetration in perforated primary molars restored with mineral trioxide aggregate (MTA) Angelus and CC. Materials and Method: This in vitro study was conducted on 50 extracted primary molars. A perforation was created in their pulpal floor by using a round-end diamond bur with 1mm diameter. The teeth were then randomly divided into 4 groups: furcal perforation repair with CC (group 1; n=20), furcal perforation repair with MTA Angelus (group 2; n=20), unrestored furcal perforation (positive control; n=5), and no furcal perforation (negative control; n=5). Bacterial leakage was evaluated using a two-chamber bacterial leakage model with Enterococcus faecalis (E. faecalis) while dye penetration was assessed stereomicroscopically by the dye penetration technique using basic fuchsin. Data were analyzed by the Mann-Whitney U, Kaplan-Meier, log-rank, Chi-square, and Fisher’s exact tests (alpha=0.05). Results: MTA and CC had no significant difference in dye penetration depth (p Value= 0.896) or bacterial leakage (p= 0.434). Conclusion: Despite the study limitations, it can be concluded that both CC and MTA have acceptable sealing properties for furcal perforation repair in primary molars under in vitro conditions since they had no significant difference in dye penetration or bacterial leakage tests. Considering the characteristics of MTA, such as its long setting time, high cost, and difficult handling, CC may be used as a suitable alternative material for treatment of furcal perforations in primary teeth. | ||
