Advances in biomaterials and understanding of pulpal healing have expanded the indications for VPT and contributed to favourable clinical outcomes; however, appropriate case selection remains a critical determinant of treatment success. Currently, the clinical assessment of pulpal status before VPT relies on a combination of patient-reported symptoms, clinical and radiographic findings, pulp sensibility testing and intraoperative assessment of pulpal bleeding. Although clinically valuable, these parameters do not provide a direct and objective measure of the biological status or healing potential of the pulp and may be influenced by clinical interpretation. Consequently, there remains a need for objective biological parameters that provide more direct information on pulpal status and healing potential, thereby supporting case selection and prognostic assessment in VPT.\n\nProgressive pulpal inflammation is accompanied by increased production of inflammatory mediators, vascular congestion, enhanced vascular permeability, impaired microcirculation, and reduced tissue perfusion. These vascular alterations may compromise oxygen delivery to the pulp, resulting in reduced pulpal oxygen saturation (SpO2). As oxygen availability decreases, cellular metabolism shifts towards anaerobic pathways, promoting the accumulation of acidic metabolites, which may consequently lead to a reduction in pulpal blood pH. Accordingly, pulpal SpO2 and pulpal blood pH may represent complementary physiological and metabolic indicators of pulpal inflammatory status. Their assessment may provide objective information on the biological condition and healing potential of the pulp that is not directly captured by conventional diagnostic methods. Consistent with these observations, Hosseinzadehfard et al. (2026) reported that pulpal blood pH and SpO2 varied with pulpal diagnostic status, supporting their potential value as objective indicators of pulpal inflammation. However, their study focused on the diagnostic relevance of these parameters rather than their association with VPT success. To date, their association with subsequent treatment outcomes and clinically relevant thresholds for outcome prediction remain to be established.\n\nThe present prospective clinical study aims to investigate the association of pulpal blood pH and pulpal SpO2, individually and in combination, with the clinical and radiographic outcome of VPT at the 12-month follow-up, and to determine clinically relevant threshold values associated with treatment success. Pulpal blood pH will be assessed both immediately after initial pulp exposure and following pulpotomy in the remaining vital pulp tissue, allowing evaluation of the relationship between the two pH measurements. Systemic oxygen saturation and venous blood pH will additionally serve as physiological reference measures. The findings may provide an evidence-based foundation for a more objective and biologically informed approach to case selection and prognostic assessment in VPT.",[27,28,29,30],"Vital Pulp Therapies","pH","pH Changes","Oxygen Saturation",[32,28,33,34],"vital pulp therapy","oxygen saturation","pulp","NOT_YET_RECRUITING","2026-09-27",{"date":38,"type":39},"2026-09-30","ACTUAL",{"date":41,"type":22},"2026-10-01",{"date":43,"type":22},"2028-08-01",{"name":45,"class":46},"ertuğrul karataş","OTHER",""]
