The cost-effectiveness of supportive periodontal care: a global perspective.

Author information

To evaluate the cost-effectiveness of supportive periodontal care (SPC) provided in generalist and periodontal specialist practices under publicly subsidized or private dental care.


SPC cost data and the costs of replacing teeth were synthesized with estimates of the effectiveness of SPC in preventing attachment and tooth loss and adjusted for differences in clinician's time. Incremental cost-effectiveness ratios were calculated for both outcomes assuming a time horizon of 30 years.


SPC in specialist periodontal practice provides improved outcomes but at higher costs than SPC provided by publicly subsidized or private systems. SPC in specialist periodontal practice is usually more cost-effective than in private dental practice. For private dental practices in Spain, United Kingdom and Australia, specialist SPC is cost-effective at modest values of attachment loss averted. Variation in the threshold arises primarily from clinician's time.


SPC in specialist periodontal practice represents good value for money for patients (publicly subsidized or private) in the United Kingdom and Australia and in Spain if they place relatively modest values on avoiding attachment loss. For patients in Ireland, Germany, Japan and the United State, a higher valuation on avoiding attachment loss is needed to justify SPC in private or specialist practices.
