Dentin Caries

This prospective, single-center, interventional post-market clinical follow-up (PMCF) study aims to evaluate the clinical performance and safety of temporary crown and bridge restorations fabricated using CE-marked ON DENT™ restorative materials throughout their functional intraoral clinical duration. A total of 120 adult patients requiring fixed prosthodontic treatments will be randomly assigned to four independent parallel groups (30 patients per group) based on the specific type of temporary material utilized: Tempo-CAD Monocolor PMMA, Tempo-CAD Monocolor SHT PMMA, Tempo-CAD Multicolor SHT PMMA, or Print On Cyclone Perma liquid resin. Patients will be monitored closely across 5 clinical visits up to a maximum duration of 6 months to assess prosthodontic survival, success rates, biological adaptations, and patient-reported quality of life outcomes.

The aim of this study is to evaluate the effect of flowable conventional and bulk-fill composites on postoperative sensitivity in class I cavities over long-term follow-up. The hypothesis to be tested in this study is that the type of composite material will not affect clinical success.

In this study, a universal adhesive was used with different adhesive techniques (self-etch and total-etch modes) and evaluated for 18 months in three different types of composite material class III and class IV restorations according to the FDI criteria. The hypotheses tested in this study are: (1) clinical success will not differ between different composite materials and (2) clinical outcomes will not differ between different application modes of the universal adhesive.

This study will be performed in two parts, in vivo and in vitro to assess the effect of the remineralization potential of self-assembling peptide P11-4 containing Fluoride on caries-affected dentin compared to untreated caries-affected dentin and the influence of Er, Cr: YSGG Laser treatment.
