Abstract

Objective. The purpose of this study was to compare both subjective (Periapical Index, PAI) and objective (densitometric) radiographic evaluation of healing after endodontic treatment for apical periodontitis. Study design. Standardized radiographs of 103 teeth taken at baseline (immediately after endodontic treatment) and at 1, 4, 12, 26, and 52 weeks wereevaluated. Consensus PAI scores obtained from 7 calibrated observers served as "true scores. " Densitometric estimates of periapical status were obtained from digitized radiographs as the ratio of mean gray value of an area of radiolucency (AR) to an adjacent and similar-sized normal (N) area (AR/N). The selected regions of interest on baseline images were automatically superimposed on postoperative images. All estimates of change were measured with respect to baseline. The subtraction estimate was expressed as AR(S)-N-S. Linear regression was used to analyze longitudinal changes against baseline and to assess the relationship of PAI and AR/N and of change in PAI with respect to baseline and AR(S)-N-S. Results. Five hundred fifty-six PAI scores were generated, with 547 AR/N values and 444 subtraction estimates. PAI, AR/N, and AR(S)-N-S demonstrated statistical significance for change (P less than or equal to .05) starting at 12 weeks. PAI was significantly correlated with AR/N (P < .0001), as wasCHPAI with AR(S)-N-S (P < .024). Conclusion. The PAI and 2 densitometric estimates (AR/N and AR(S)-N-S) detected healing of apical periodontitis at 12 weeks after treatment. No difference could be observed among the methods.
