The application of biomimetic strategies and nanotechnologies (nanodentology) has led to numerous innovations and provided a considerable impetus by creating a new class of modern adhesion restoration materials, including different nanofillers. An analysis of the molecular properties of biomimetic adhesives was performed in this work to find the optimal composition that provides high polymerisation and mechanical hardness. Nanocrystalline carbonate-substituted calcium hydroxyapatite (nano-cHAp) was used as the filler of the light-cured adhesive Bis-GMA (bisphenol A-glycidyl methacrylate). The characteristics of this substance correspond to the apatite of human enamel and dentin, as well as to the biogenic source of calcium: avian eggshells. The introduction and distribution of nano-cHAp fillers in the adhesive matrix resulted in changes in chemical bonding, which were observed using Fourier transform infrared (FTIR) spectroscopy. As a result of the chemical bonding, the Vickers hardness (VH) and the degree of conversion under photopolymerisation of the nano-cHAp/Bis-GMA adhesive increased for the specified concentration of nanofiller. This result could contribute to the application of the developed biomimetic adhesives and the clinical success of restorations.

Article Synopsis
- The study investigated how different surface treatments affect the color of enamel and dentin in teeth.
- It found that prolonged acid-etching significantly altered the color of enamel, exceeding acceptable limits, while dentin color remained stable regardless of treatment.
- The research suggests that clinicians should minimize acid-etching time to prevent undesirable color changes in enamel for better aesthetic outcomes.

Objectives: To evaluate the effect of different zirconia compositions and manufacturing processes on the light irradiance (LI), to measure the degree of conversion (DC) of solely light-curing restorative composite underneath these zirconia grades and to evaluate the respective zirconia microstructures.
Methods: Six dental zirconia grades (GC HT, GC UHT [GC]; Katana HT, Katana UTML [Kuraray Noritake]; Lava Esthetic, Lava Plus [3 M Oral Care]) were cut and sintered per manufacturer instructions. One 3D-printed zirconia grade (XJet [XJET]) was prepared according to previous research.

Objectives This study aimed to compare the shear bond strength of three resin cements (light-cured resin cement, pre-heated composite resin, and dual-cured self-adhesive resin cement) when bonding to lithium disilicate discs. Materials and methods Thirty-six discs made of lithium disilicate were fabricated and etched with 9.5% (HF), and 36 human premolars were collected and immersed in the acrylic molds, then randomly divided into three equal groups (n = 12): Group 1: light-cured resin cement, Group 2: pre-heated resin composite, and Group 3: dual-cured resin cement.
