Background and Aim: Dentinal tubules are exposed to the oral environment during preparation of vital teeth for crown restorations, and patients show signs of tooth hypersensitivity. Some treatments have been suggested for dentin hypersensitivity after tooth preparation, such as diode laser (810 nm) irradiation and GLUMA desensitizer. This study aimed to assess the effects of 810 nm diode laser and GLUMA desensitizer on retention of porcelain-fused-to-metal (PFM) frameworks cemented with a self-adhesive resin cement.
Materials and Methods: This in vitro study evaluated 30 intact maxillary first premolars. After tooth preparation with a 0.5 to 0.7 mm finish line above the cementoenamel junction, full metal crowns were cast with a 5 mm diameter ring on their occlusal surface. The specimens were then divided into 3 groups (n=10) of control, 810 nm diode laser, and GLUMA desensitizer. The frameworks were cemented with RelyX U200 self-adhesive resin cement, and their retention was measured by a universal testing machine. Data were analyzed by ANOVA and Tukey post-hoc test (alpha=0.05).
Results: There was no significant difference in retention between 810 nm diode laser (134.96±37.50 N) and the control (138.17±40.81 N) group (P=0.986). However, framework retention in GLUMA desensitizer group (318.59±56.31 N) was significantly higher than that in other groups (P<0.05).
Conclusion: In this in vitro study, GLUMA desensitizer had a significant positive effect while 810 nm diode laser irradiation did no not have any significant effect on retention of PFM frameworks cemented by RelyX U200 self-adhesive resin cement.
