Objectives: To investigate the effectiveness of modified ART class IV restorations in a one-year follow-up interventional study with historical control.

Materials and Methods: In 69 adults one modified class IV ART restoration per subject was placed at a public dental ward in Gambia in 2012 by one community oral health worker. Historical controls were 12-months data collected in 2005 in 61 patients with original ART class IV anatomical structure rebuilding restorations. One independent examiner evaluated the restorations according to ART evaluation criteria (secondary outcome parameter). Primary outcome parameter was the annual failure rate.

Results: Modified class IV ART performed significantly better compared to historical controls in short-term 12 months follow-up (p<0.001). The annual failure rate in modified class IV ART was 19.2% and was 83.6% in historical controls.

Conclusions: One-year performance was close to multiple-surface ART restorations in permanent teeth using high-viscosity glass ionomer cements.

Clinical Relevance: Class IV cavities might be treated with modified ART technique in dentally underserved areas.
