Introduction: Preparation of vital teeth involves removal of sound tooth structure, which causes opening of dentinal tubules, thereby causing displacement of the dentinal tubular fluid, leading to dentinal hypersensitivity. After cementation of crowns in such teeth, incidence of pain and hypersensitivity has been reported. An extensive use of desensitizing agents has been observed over the past few decades because of the introduction of newer agents and the increased incidence of post-cementation sensitivity. Dentin desensitizing agents are commonly used in dental practice. But their effects on crown retention have been anecdotal. Materials and Methods: Thirty-three extracted human maxillary first premolar teeth were selected for the study, which were prepared using a special assembly and divided into three groups (i.e., ZP + U, ZP + G, and ZP) to compare the effect of Gluma (Heraeus-Kulzer, Germany) and Ultraseal (Ultradent, USA) on crown retention using zinc phosphate cement. Results: It was seen that the group ZP + G was statistically significant with groups ZP and ZP + U. However, no such difference was observed between ZP and ZP + U. Conclusion: Both the agents can be used and prove effective when used with zinc phosphate cement. However, the major mode of failure was adhesive in nature with the cement being retained on both the crown and the tooth structure. |
