Comparison of Post Cementation Sensitivity Between Resin-Modified Glass Ionomer Cement and Conventional Glass Ionomer Cement as a Luting Material: A Randomized Clinical Trial
Comparison of Post Cementation Sensitivity Between Resin-Modified Glass Ionomer Cement and Conventional Glass Ionomer Cement as a Luting Material: A Randomized Clinical Trial
This randomized controlled trial aims to compare post-cementation sensitivity between resin-modified glass ionomer cement (RMGIC) and conventional glass ionomer cement (GIC) as luting materials. Conducted at the Prosthodontics Department, Saidu College of Dentistry, Swat, the study will enroll 248 patients aged 15-70 with vital abutment teeth, randomly assigned to receive either RMGIC or GIC. Sensitivity will be assessed using a 10-point Visual Analog Scale (VAS), with scores above 1 considered indicative of post-operative sensitivity and further categorized for analysis. Strict inclusion/exclusion criteria and randomization will control bias and confounders. Data will be analyzed in SPSS 22 using t-tests and chi-square tests, with significance set at p≤0.05.
Dental prostheses are frequently used to replace missing teeth. Fixed partial dentures are regarded as the gold standard for restoring lost teeth, aiming to recover proper function, speech, and appearance. These fixed prostheses must be securely attached to the neighboring teeth using specific bonding agents known as luting cements. Ideal luting materials should exhibit low solubility, biocompatibility, resistance to leakage, and should not cause discomfort or sensitivity after cementation. Common luting agents include glass ionomer cement (GIC), resin-modified glass ionomer cement (RMGIC), zinc phosphate cement, and zinc oxide eugenol cement. Among these, GIC and RMGIC are considered reliable and long-lasting choices for luting purposes.
