Summary
This is a split-mouth, double-blind randomized controlled trial. Computerized linear
radiographic measurements were used to detect infrabony defects treated with open flap
debridement (OFD) or OFD associated with enamel matrix derivative (EMD), after 24 months. Ten
patients presenting 2 or more defects were selected (43 defects). An individualized film
holder was used to take standardized radiographs at baseline and after 24 months. Images were
digitized and used to measure the distances from the cemento-enamel junction (CEJ) to the
alveolar crest (AC), CEJ to the bottom of the defect (BD) and infrabony defect angle.
