- Comparison of two CBCT analysis techniques with conventional periapical radiographs in assessment of tertiary dentin after indirect pulp capping in young permanent teeth Marwa Baraka Lucia Cevidanes Antonio Ruellas Erika Benavides Nourhan Aly Margherita Fontana International Journal of Paediatric Dentistry AbstractBackground and aimTo compare two cone beam computed tomography (CBCT) analysis techniques for measuring tertiary dentin (TD) volume, density, and root length increase, after indirect pulp therapy (IPT) in young permanent teeth with conventional periapical radiographs.DesignComparative study design: Sixty‐nine CBCT scans were taken initially (T1) and after 1 year (T2) of IPT. New CBCT analysis technique A, standardization, segmentation, and registration of T1 and T2 scans were performed using ITK‐SNAP and 3D Slicer CMF to measure TD volume (mm3), density (gray‐level intensity), and root length increase (mm). In the traditional CBCT analysis technique B, analyses were conducted using the In‐Vivo software to calculate TD thickness (mm), radiodensity (HU%), and root length increase (mm). Paired t‐test and the intraclass correlation coefficient were calculated to compare and assess the reliability of all techniques.ResultsNo significant difference between the two techniques existed in the measurement of TD mineral density (Mean [SD]:A = 22.4 [15.4]; B = 24.4 [15.4]; p = .47). Technique A resulted in significantly higher root length increase values (Mean [SD]: A = 1.3 [0.6]; B = 1.1 [0.5]; p = .03). The two techniques showed acceptable reliability levels (0.76–0.99).ConclusionCBCT analysis techniques yielded similar findings for mineral density. The new CBCT volumetric analysis technique, although more laborious, produced higher values for root length increase, and allowed for measurement of dentin volume. 10.1111/ipd.13232 http://onlinelibrary.wiley.com/termsAndConditions#vor
