Abstract

Objective: The main objective of endodontic treatment is to remove microorganisms from the root canal space and prevents reinfection. Deep penetration of the dentinal tubule is advantageous because it increases the contact area between the root canal filling material and dentin, thereby increasing the sealing quality of the entire root canal system. Bioceramic sealers are biocompatible, nontoxic, non-shrinking, hydrophilic, and stable, do not expand during setting, and can form hydroxyapatite, which then forms chemical bonds with dentin to compare the abilities of three types of bioceramic-based sealers to penetrate the dentinal tubules.Methods: Obturation used three types of bioceramic sealers. Group 1 (calcium phosphate silicate), Group 2 (a mixture of tricalcium silicate and resin), and Group 3 (pure tricalcium silicate) were observed using a scanning electron microscope and measurement of the penetration distance with ImageJ.Results: The bioceramic sealers had statistically significant differences in penetration distance into dentinal tubules (p’s<0.001). The mean penetration value of Group 1 (calcium phosphate silicate) was 115.99 μm, Group 2 (a mixture of tricalcium silicate and resin) was 209.28 μm, and Group 3 (pure tricalcium silicate) was 84.07 μm.Conclusion: Although all three bioceramic sealers penetrated the dentinal tubules, they exhibited differences in their penetration capabilities. Group 2 had the deepest penetration, likely due to the resin content.

Highlights

The main goals of root canal treatment are to eliminate root canal microorganisms and to prevent root canal reinfection following treatment [1]
Deep penetration of dentinal tubules is advantageous because it increases the contact area between the root canal filling material and dentin, thereby increasing the sealing quality of the entire root canal system [4]
The sealer penetration depth depends on many factors, including smear layer cleanliness, dentin permeability, root canal dimensions, and the physical and chemical properties of the sealer [5]

Summary

Introduction

The main goals of root canal treatment are to eliminate root canal microorganisms and to prevent root canal reinfection following treatment [1]. A hermetic root canal filling must be obtained using a sealer between the dentin wall and gutta-percha, a requirement referred to as the “monoblock” concept. “Monoblock” indicates the creation of a strong, solid, and comprehensive root canal between the material and root canal wall to prevent bacteria from entering the root canal system [2]. Along with the removal of debris and bacteria, good adaptation to the dentinal wall is essential to achieve an optimal root canal filling. This can be seen from the penetration of the material into the dentinal tubules [3]. The sealer penetration depth depends on many factors, including smear layer cleanliness, dentin permeability, root canal dimensions, and the physical and chemical properties of the sealer (flow rate) [5]
