“…When the concentration of GO-MMT was 0.3 wt%, the product had the highest flexural strength and microhardness compared to the other formulations. MMT-Bis-GMA/TEGDMA [52,53] Filler in low-shrinkage dental composite Sodium MMT (Na + MMT) had an effect on flexural modulus, flexural strength, degree of conversion, steady-state shear viscosity and viscosity of the Bis-GMA/ TEGDMA resin complex. The results showed that the incorporation of up to 0.3 phr of Na + MMT improved the mechanical and chemical properties.…”

Montmorillonite (MMT) is a biocompatible, cost-effective phyllosilicate mineral clay material with a nanolayered structure belonging to the smectite group. MMT is frequently used as an adsorbent catalyst in organic synthesis, food additives, cosmetics, medical applications and many other applications in varying industries. MMT has been incorporated into numerous experimental dental restorative materials as a reinforcing filler due to its high aspect ratio, forming interfacial solid bonds with the polymer matrix. The relatively high cation exchange capacity and layered structure of MMT pave the way as a medium for drug delivery systems. Furthermore, the incorporation of ions such as calcium, fluoride, silver, and zinc potentially increase the remineralization properties and antibacterial properties of MMT-based dental materials. Despite modern dental restorative materials having advanced significantly with innovations in material nanoscience, challenges such as biocompatibility, inadequate mechanical properties, marginal leakage, polymerization shrinkage, aesthetic concerns, and overall costs remain to be addressed. This review investigates the potential of montmorillonite (MMT) in dentistry, emphasizing its distinctive properties, composite formulations, and applications. It assesses the current state of research in these areas, aiming to highlight existing gaps in knowledge, emerging trends, and lesser-known applications of MMT-based materials. The review underscores MMT's promise as an alternative material across various dental applications while noting the scarcity of research on completed products and in vivo clinical studies.

“…In [21], there is a presentation of the possibility to provide a modification of the surface through a chemical reaction using specific polymers in the course of the curative process, contributing to avoiding further development of caries. In [22], the authors studied how some polymer materials when dispersed in water have an important effect on some mechanical properties of the teeth structure. Vat-polymerization additive manufacturing (AM) methods for the development of dental parts, containing different resins based on acrylic esters as main component have gained popularity in present times.…”

Nowadays in our society modern science uses a wide range of materials to perform multiple functions. One of the fields in which biological, synthetic and hybrid materials have found various applications is related to the medical one. The variety of materials used in medicine adapts to specific requirements and applications, due to the wide range of physical, chemical and biological properties that these materials can guarantee. The present review paper offers a short review, based on the data available in the scientific literature, on the possibility of using materials for dental application.

“…Most of the resins used for dental applications are based on acrylic monomers such as bis-GMA, TEG-DMA, and UDMA [3,[7][8][9][10], which are further coupled by silanized agents to form the polymer matrix. Filler particles could be crystalline such as quartz, hydroxyapatite, tri-calcium phosphate, and zirconia [11][12][13] or amorphous such as glass (such as barium oxide or lithium disilicate glasses) [14,15].…”

(1) Background: the current study investigated three nanohybrid composites: two commercial products ClearfilMajestyTM (CM) and HarmonizeTM (HU), compared with an experimental product PS2. (2) Methods: Two sample types were molded using Teflon dies. The first sample type was represented by standard discs (20 mm diameter and 2 mm thickness) (n = 60, 20/each material), used for surface conditioning investigation, specifically roughness monitoring and color stability analysis using AFM and the CIELab test, respectively. The second sample type was a standard cylindrical specimen (4 mm diameter and 6 mm height) for compression testing (n = 60, 20/each material). After complete polymerization, the samples were ground with sandpaper and further polished. The filler size and distribution in the polymer matrix were investigated with SEM. Data were statistically analyzed using the Anova Test followed by Tukey’s post hoc test on the Origin Lab 2019 software produced by OriginLab Corporation, Northampton, MA, USA. (3) Results: A mono-disperse system was identified in HU samples, while CM and PS2 revealed both nano- and microfiller particles. The samples’ observation after immersion in coffee and tea indicated that a lower roughness combined with optimal filler lamination within the polymer matrix assured the best color preservation. The compression strength was lower for the HU sample, while higher values were obtained for the complex filler systems within CM and PS2. (4) Conclusions: the behavior of the investigated nanohybrid composites strongly depends on the microstructural features.
