Results at One Year
Lack of Postoperative Sensitivity
Patients reported some level of sensitivity associated with 5% of the 96 restorations recalled at one year. In three of these cases, patients experienced a moderate level of sensitivity immediately after placement and a decrease in sensitivity over time until they were asymptomatic. Two of these patients had restorations placed with bonding agent. One restoration was replaced due to an air bubble which was detected in a subsequent radiograph, and one was a very deep restoration which eventually needed root canal therapy. ese conditions do not appear to be associated with the restorative material selected. No sensitivity was reported by patients at one year recall.
The esthetics of the restorations was excellent (Figure 3). Ninety-six percent of recalled restorations received a rating of 5, whereas 2% received a rating of 4, and 2% received a rating of 3.
Resistance to Fracture/Chipping
Resistance to fracture and chipping were excellent. None of the recalled restorations exhibited any fracture or chipping.
Resistance to Marginal Discoloration
Resistance to marginal discoloration was rated as excellent (Figure 3). ere were no observations of marginal staining at one year.
Ninety-nine percent of the restorations
exhibited no signs of wear (Figure 3). Only one
of the recalled restorations exhibited some wear and received a rating of 3.
Retention was excellent (Figure 3) – there were no debonds at the one-year recall.
