Aims: To evaluate and compare the wettability of root canal sealers after using various irrigants. To determine wettability, we evaluated the contact angle, because lower the contact angle, better the wettability. Green tea has antibacterial and anti-inflammatory properties; therefore, it was used as an irrigant. Materials and Methods: Seventy-two freshly extracted, human, single-rooted teeth were used in the study. The roots were split into 144 dentin sections. The specimens were divided into the following four groups having 36 samples each: Group I—sodium hypochlorite 3%, Group II—chlorhexidine (CHX) 2%, Group III—green tea extract, and Group IV (control)—normal saline. The groups were further subdivided based on the sealer used. Results: There was highly significant difference among the mean contact angle values of zinc oxide eugenol sealer, AH Plus sealer, and MTA Fillapex sealer using 2% CHX (P < 0.01). The least contact angle was observed with green tea as root canal irrigant and MTA as root canal sealer (25.20 ± 4.00). Conclusion: The type of irrigant used had an influence on the contact angle of sealer. Among all the irrigants and sealers used in this study, the least contact angle was observed with green tea root canal irrigant and MTA Fillapex sealer.
