The management of an endodontically abscessed tooth: patient health state utility, decision-tree and economic analysis

Table 4 Cost-Utility-Analysis AND Cost-Benefit Analysis (5-year).

			Cost Utility			Cost-Benefit
Tooth	Treatment Option	Treatment cost ($CND)	EUV (utile)	QATY^β (utile-yr)	Cost: Utility^β (CND$ per utile-yr of tooth survival)	Expected Benefit Value (CDN$)	Cost: Benefit^β ($ paid per dollar of benefit received)

β-QATY = EUV × 5 years. Cost:Utility = Treatment cost/QATY, Cost:Benefit = Treatment cost/Expected Benefit Value.
γ – These cost of CDB option takes into account the 2.4% risk that one of the abutment teeth will incur the cost of root canal therapy in the future.
