A Comparison of Various Cementation Methods for the Retention of Prefabricated Posts: An Original Research
Abstrak
Objective: To evaluate and compare the retention strengths of prefabricated posts cemented using zinc phosphate (ZP), glass ionomer (GIC), and resin cements (RC). Methodology: About 60 extracted human mandibular premolars were decoronated to a standardized length and endodontically treated. Post spaces were prepared to a depth of 10 mm, were grouped into 20 each. Prefabricated metal posts were cemented according to the manufacturers’ instructions. Tensile forces until post dislodgment were measured after one day. Results: Mean retention strengths were: Group A (ZP)—124 N, Group B (GIC)—336.86 N, and Group C (RC)—1262.51 N. RC exhibited significantly higher retention than both GIC and ZP cements, and GIC cement showed significantly higher retention than ZP cement. Conclusion: The type of luting cement significantly affects the retention of prefabricated posts. RC demonstrated the highest retention strength, suggesting its superiority for clinical applications requiring enhanced post-retention.
