Correlación entre los hallazgos clínicos y radiográficos para el diagnóstico de lesiones endoperiodontales.

Abstract

Introduction: Endoperiodontal lesions affect pulpal and periodontal tissues through anatomical structures such as canals, apical foramina, and dentinal tubules, presenting clinical and radiographic findings that must be evaluated in a complementary manner. Objective: To analyze the correlation between clinical diagnosis and radiographic findings for the diagnosis of endoperiodontal lesions. Materials and methods: An observational, analytical, and cross-sectional study was conducted with 56 teeth from 52 patients. To establish the correlations between clinical variables and radiographic bone loss, Spearman's rho and 95% confidence intervals were used with cluster bootstrap analysis (10,000 resamples). Results: 100% of the sample showed a negative response to sensitivity tests. A probing depth ≥ 4 mm was the most prevalent (87.5%) and showed a moderate correlation with radiographic bone loss (ρ = 0.447; 95% CI: 0.256–0.597). Clinical attachment loss showed the strongest correlation (ρ = 0.889; 95% CI: 0.834–0.929), followed by tooth mobility (ρ = 0.574; 95% CI: 0.390–0.704). Discussion: Pulp sensitivity was consistent with the literature, but its lack of variability prevented the establishment of associations. Tooth mobility, clinical attachment loss, and probing depth showed positive correlations with radiographic bone loss, with the strongest correlation being between clinical attachment loss and radiographic bone loss (ρ = 0.889). This finding highlights the importance of jointly evaluating clinical and radiographic aspects. Conclusion: Periodontal parameters showed a positive correlation with radiographic bone loss and endoperiodontal lesions.
