![]() A logistic regression accounting for measurement errors provided odds ratios that estimated the ability of the RDT/TDT to predict pulp exposure.ResultsThe median RDT/TDT ratio ranges were 16.8–26.5% on standard and 16.2–24.6% on contrasted radiographs. Inter-rater agreements and concordance were assessed. Lines put at the dentino-enamel junction, the floor of the carious lesion, and the pulp chamber wall allowed deriving RDT/TDT. Four independent raters examined standard pre-operative radiographs and their contrasted versions. ![]() This retrospective study (January 2018–June 2020) analyzed data on 360 patients. Current pre-operative radiographs allow visual estimation but not accurate measurement of lesion depth.PurposeInvestigate the ability of ratio ‘remaining/total dentin thickness’ (RDT/TDT, as determined on pre-operative radiographs) to predict pulp exposure during excavation.Methods During interventions for deep caries lesions without severe symptoms, preserving pulpal vitality is important to ensure treatment success, improve organ prognosis, and decrease cost-effectiveness.
