Effect of immediate dentin sealing on preventive treatment for postcementation hypersensitivity.
OBJECTIVE
The aim of this study was to investigate the effect of Prime and Bond adhesive on preventing postcementation hypersensitivity of vital abutment teeth restored with a full-coverage restoration using the immediate dentin sealing (IDS) technique.


METHODS
Twenty-five male patients received 25 three-unit fixed partial dentures. A split-mouth design was used and two vital abutment teeth in each patient were allocated randomly into Groups A or B. Teeth in Group A were treated with Prime and Bond using the IDS technique while teeth in Group B were used as a control and left untreated. The discomfort interval scale, ranging from 0 to 4, was adopted to evaluate hypersensitivity. The double-blind method was applied during the operation so that neither the patient nor the clinician knew which abutment had been treated. The sensitivity assessment was performed 1 week, and 1, 6, 12, and 24 months after cementation. RESULTS were analyzed using the sign test.


RESULTS
Scores for teeth in Group A were statistically significantly lower than those in Group B at 1 week and 1 month postcementation (P < .05), whereas there was no significant difference between Groups A and B at the end of 6, 12, and 24 months (P > .05).


CONCLUSIONS
Preventive treatment with Prime and Bond using the IDS technique can significantly reduce postcementation hypersensitivity. Int J Prosthodont 2010;23:49-52.
