Title Adhesive Resin Cements are More Effective Than Glass Ionomer Cements at Lessening Post-Operative Sensitivity After the Placement of a Full Coverage Crown
Clinical Question In patients receiving a full coverage crown, does glass ionomer cement cause less post-operative sensitivity than adhesive resin cement?
Clinical Bottom Line Adhesive resin cements may cause less post-cementation sensitivity than glass ionomer cements when used for crown and bridges.

PubMed ID Author / Year Patient Group Study type
(level of evidence)
#1) 22918005 Shetty/201250 patients receiving full coverage restorations on vital abutment teeth.Randomized Controlled Trial
Key resultsIn the study using 50 patients each receiving a full coverage crown all patients were available for the 7 day follow-up. Hypersensitivity was checked using a visual analog scale ranking 0-10, 10 being the worst and 0 being painless. There was no statistical evidence of hypersensitivity immediately or 24 hours after cementation. However, there was a statistically significant difference between the cements at 7 days post-cementation with a significance of 0.05. There was a higher sensitivity rating for glass ionomer cement compared to the adhesive resin cement.

The Evidence
This randomized controlled trial was done with 50 patients, all of whom needed a full coverage crown. There was a 100% completion and follow-up rate. The patients were split into 2 groups of 25 each, one receiving glass ionomer cement and the other receiving adhesive resin cement. It was a single blind test with full compliance and no competing interests involved.
Applicability This is applicable to any patient receiving a full coverage crown. The dentist should consider post-cementation hypersensitivity in addition to retention, when choosing a luting agent for crown and bridge procedures.
