The Sealing Ability of New Bioceramic Material Used to Repair Furcal Perforation Compared with the Traditional Repair Materials: UV Spectrophotometer Analysis

Iatrogenic furcal root perforations are serious complications during dental treatment. This study was aimed to compare the sealing ability of new bioceramic root repair material TotalFill with the other perforation repair materials (GIC, MTA and Biodentine) using a dye- extraction method. Materials and Methods Forty extracted, human mandibular molars with non-fused well developed root were collected. Artificial perforations were made from the external surface of the teeth. Then the teeth were randomly divided into 4 experimental groups (n= 10) according to the type of repair material used in this study, Medifil glass ionomercement, TotalFill bioceramic root repair material, BiodentineTM and MTA Plus. The specimens were then immersed in 4 % methylene blue dye up to the CEJ for 48 hours followed by dye extraction with 65 % nitric acid for 3 days. The samples were analyzed using ultraviolet (UV) visible spectrophotometer. Data obtained were analyzed using one way ANOVA and Tukey tests at 0.05 significant levels. Results Statistical analysis showed highly significant differences (Pless than0.05) among tested materials. Lower absorption values occurred with TotalFill group fallowed by biodentine and MTA but higher absorption occurred with GIC group. One Way ANOVA showed highly significant differences (Pless than0.05) among the groups. Tukey test showed highly significant differences when compared TotalFill and Biodentine groups with GIC and significant difference with MTA Plus group, but among TotalFill, Biodentine and MTA Plus groups the results were non- significant. Conclusion TotalFillshowed better furcation sealing ability as compared to Biodentine and MTA Plus materials but with no significant differences.
