: The success of treatment and prevention for secondary caries hinges significantly on the techniques employed in Class II composite restoration. Additionally, the location of the restored tooth within the oral cavity has emerged as a potential factor determining the quality of the restoration. A comprehensive understanding of these interrelated variables is crucial for advancing the efficacy and durability of dental composite restorations.

Statement Of Problem: Staining at the gingival margin could impact denture longevity, but the behavior of gingival colored composite resins (GCCs) in this area remains unclear.
Purpose: This in vitro study evaluated surface staining, microleakage, and push-out bond strength at the gingival margin of artificial teeth, comparing two consistencies of GCCs with two resin base materials.
Material And Methods: Specimens included artificial teeth (Ivostar; Ivoclar AG) and two acrylic resin base materials: conventional (Ondacryl; Clássico) and high-impact (Diamond D; Keystone Industries) (n=300).
Primary Dentin Conditioning with Methylene Blue Activated Photodynamic Therapy, Phytic Acid, and Er,Cr:YSGG to Resin-Modified Glass Ionomer Cement in Comparison to Conventional Polyacrylic Acid.

Impact of surface conditioner phytic acid (IP6) Er,Cr:YSGG laser (ECYL) methylene blue photodynamic therapy (MB-PDT) on the microleakage and shear bond strength (SBS) of resin-modified glass ionomer cement (RMGIC) to primary sound dentin. Overall, 80 extracted sound primary molars were collected followed by their submergence in self-cure acrylic resin. The dentin surface was exposed and made flat and was assigned into four groups based on the surface conditioning.

Key Lab for Biomechanical Engineering of Sichuan Province, Sichuan University, Chengdu, China; Sichuan University Yibin Park, Yibin Institute of Industrial Technology, Yibin, China. Electronic address:
Objective: This study aims to investigate adhesive damage caused by the synergistic effects of polymerization shrinkage and occlusal forces via finite element analysis (FEA), based on damage mechanics with the cohesive zone model (CZM). The objective is to obtain the adhesive damage distribution and investigate how the material properties of resin composite impact adhesive damage.
Methods: A 3D reconstruction model of an mandibular first molar was constructed through CBCT imaging, and a Class V cavity was prepared using computer-aided engineering (CAE) software.
Comparative Evaluation of Microleakage in Class V Cavities Restored with Newer Bioactive Restorative Materials: Activa Bioactive Restorative and Activa Pronto.
Int J Clin Pediatr Dent
November 2024
Private Practitioner, Bengaluru, Karnataka, India.
Aim: To compare the microleakage in class V cavities restored with Activa Bioactive Restorative, Activa Pronto, and nanohybrid composite.
Materials And Methods: Standardized class V cavity preparations (mesiodistal: 3 mm; occlusocervical: 2 mm; axial depth: 1 mm) were made on the buccal surface of 60 extracted intact maxillary premolar teeth. The preparations were divided into three experimental groups ( = 20) depending on the restorative material used.
