Nanotechnology utilizes the mechanics to control the size and morphology of the particles in the required nano range for accomplishing the intended purposes. There was a time when it was predominantly applied only to the fields of matter physics or chemical engineering, but with time, biological scientists recognized its vast benefits and explored the advantages in their respective fields. This extension of nanotechnology in the field of dentistry is termed ‘Nanodentistry.’ It is revolutionizing every aspect of dentistry. It consists of therapeutic and diagnostic tools and supportive aids to maintain oral hygiene with the help of nanomaterials. Research in nanodentistry is evolving holistically but slowly with the advanced finding of symbiotic use of novel polymers, natural polymers, metals, minerals, and drugs. These materials, in association with nanotechnology, further assist in exploring the usage of nano dental adducts in prosthodontic, regeneration, orthodontic, etc. Moreover, drug release cargo abilities of the nano dental adduct provide an extra edge to dentistry over their conventional counterparts. Nano dentistry has expanded to every single branch of dentistry. In the present review, we will present a holistic view of the recent advances in the field of nanodentistry. The later part of the review compiled the ethical and regulatory challenges in the commercialization of the nanodentistry. This review tracks the advancement in nano dentistry in different but important domains of dentistry.

This study aimed to compare the amount of fluoride uptake and the recharge and release characteristics of conventional glass ionomer cement (GIC) without any additives in comparison to conventional glass ionomer cement supplemented with silver nanoparticles (AgNPs) at two concentrations: 0.1% and 0.2% (w/w). A total of 60 specimens were used in this in vitro study. The sample was divided into six groups—including three groups without fluoride charge: Group 1 (conventional GIC), Group 2 (GIC with 0.1% silver nanoparticles), and Group 3 (GIC with 0.2% silver nanoparticles; and three groups with fluoride charge: Group 4 (conventional GIC with fluoride); Group 5 (GIC with 0.1% silver nanoparticles with fluoride); Group 6 (GIC with 0.2% silver nanoparticles with fluoride), where Group 1 is considered the control group and the other five groups are used as the test groups. The amount of fluoride released was measured on days 1, 2, 7, 15, and 30. The comparisons were made between the groups with and without fluoride and among all the groups. A significant difference in the amount of fluoride released was observed between the groups, with the highest amount occurring in Group 1, followed by Group 2; the lowest amount of fluoride released was observed in Group 3 (p < 0.05). The groups with fluoride recharge (Groups 4, 5, and 6) exhibited a higher amount of fluoride release than the groups with no recharge (Groups 1, 2, and 3); however, Group 1 has more fluoride release compared to all other groups on days 1, 2, 7, 15, and 30 (p < 0.05). The amount of released fluoride decreased from day 1 to day 30 in all of the groups in the study. Despite the antimicrobial and anticariogenic benefits of adding silver nanoparticles to GIC, it seems that fluoride release characteristics are significantly affected by the addition of this material. This may force the clinician to a compromise between the antimicrobial benefit of silver nanoparticles and the remineralizing advantage of fluoride.

“…It is reported that fabricating scaffolds with optimal pore size, it is possible to maintain oxygen tension and pH levels inside a scaffold that are nearly identical to values measured on the scaffold's exterior. These scaffolds, known as oxygen tension controlled matrices, have been shown in vitro and in static culture to support cell proliferation and mineralization throughout the scaffold structure (i.e., fully osteoconductive), and they may have the potential to repair largescale or critical-size bone defects in vivo (35)…”

Human bone is susceptible to damage from infections, fractures, and diseases. They do, however, have an amazing ability to repair themselves after being exposed to such factors, which is accomplished by a dynamic process of remodeling, maturation, differentiation, and regulated resorption. Larger defects, on the other hand, cannot be fully restored because their sizes exceed the capacity of the bones to repair. In such cases, medical intervention is required to stabilize, align, and support the damaged bone region so that lost function is restored. The goal of Bone Tissue Engineering is to incite and promote the natural healing process of bone, which does not occur in critical-sized defects. A biocompatible synthetic bone scaffold must be biodegradable to allow native tissue integration and must mimic the multidimensional hierarchical structure of native bone. Several biomaterials have been studied for their potential as bone scaffold materials, including ceramics, metals, polymers, and composites. Polymers, on the other hand, have emerged as the primary material in bone tissue engineering due to their tunable physiochemical properties, biocompatibility, and controllable biodegradability. This literature review provides insight into current trends in bone graft
