Tooth Sensitivity

This study evaluates the clinical performance, marginal integrity, surface wear, color stability, and postoperative sensitivity of graphene-reinforced CAD/CAM indirect restorations (inlays, onlays, overlays) in molars affected by moderate to severe Molar-Incisor Hypomineralization (MIH) in adolescents. A total of 30 patients aged 10-16 years will receive minimally invasive indirect restorations fabricated from a nano-reinforced graphene polymer (G-CAM®). Clinical outcomes will be assessed using FDI criteria, VAS sensitivity scores, patient satisfaction, and digital 3D scans over a 12-month follow-up. The study aims to determine clinical acceptability and safety compared with historical outcomes reported for composite and lithium-disilicate indirect restorations.

The aim of this study is to evaluate the effect of single versus multiple application protocols for in-office dental bleaching using two different bleaching gels (Pola Office Plus, SDI, 37.5% HP and Opalescence Boost, Ultradent, 40% HP) on the risk and intensity of tooth sensitivity, as well as the effect of the application protocol on the bleaching efficacy. Null hypothesis: There is no difference in intensity and risk of tooth sensitivity between single and multiple application of each gel and the application protocol dose not present significant effect on the bleaching efficacy.
