Modern restorative dentistry is continuously evolving towards approaches that are minimally invasive and prioritize the preservation of tooth structure and pulp vitality. Traditional methods of caries removal often lead to the unnecessary excision of healthy dentin, increasing the likelihood of pulp exposure and subsequent complications. Recent developments in restorative materials and adhesive strategies, alongside enhanced insights into caries pathology, have set the stage for selective caries excavation, vital pulp therapy, and better management of the smear layer. These innovations aim at maintaining dental health, lengthening the life span of restorations, boosting remineralization, and decreasing caries incidence beside restorations. Moreover, the increasing prevalence of root caries, especially in elderly individuals, poses fresh challenges that lack effective evidence-based interventions with high success rates.

This Research Topic aims to explore the current challenges and breakthroughs in restorative materials and techniques for the preservation of enamel, dentin, and pulp. We strive to emphasize clinical and scientific progress in selective caries excavation and vital pulp therapy, including regenerative techniques aimed at maintaining or restoring pulp vitality in deep carious lesions. Examination of the smear layer modifications following cavity preparation and its implication on adhesive strategies and the durability of restorations will also be discussed. Furthermore, we encourage papers on innovative approaches to managing root caries, particularly in aging populations with distinct clinical requirements. This Research Topic endeavors to propel evidence-based recommendations and foster further innovation in minimally invasive, biologically driven restorative dentistry by compiling original research, clinical studies, and reviews.

To gather further insights in the diverse and evolving landscape of restorative dentistry, we welcome articles addressing, but not limited to, the following themes:

▪ Selective caries excavation and bonding to sound and caries-affected dentin

▪ Vital pulp therapy and techniques for inducing mineralization for pulp preservation

▪ Smear layer modifications and their implications for adhesive strategies

▪ Innovative restorative materials promoting remineralization and antibacterial properties

▪ Strategies for managing restorative root caries, particularly in elderly populations

▪ Approaches for tubule occlusion in treating dentin hypersensitivity

▪ Therapeutic solutions for dental developmental defects

We welcome original research articles, clinical studies, systematic or narrative reviews, and case reports. Manuscripts should present new findings, clinical protocols, or comprehensive reviews related to the advancements in restorative materials and dentin preservation. Contributions from both laboratory-based and clinically-oriented studies are encouraged. Authors are invited to delve into challenges, recent advancements, and future perspectives aimed at the advancement of restorative dentistry.
