Nanotechnology is revolutionising the field of dentistry by transforming the development and application of dental materials. At its core, nanotechnology involves the manipulation and manufacture of materials and devices at the nanometre scale – a realm where individual atoms and molecules are manipulated to create novel materials. These advancements have paved the way for dental nanomaterials that exhibit superior properties, such as enhanced mechanical strength, improved aesthetic qualities, and increased durability, vastly improving the quality of dental care.
Incorporating nanotechnology into dentistry has led to the creation of various innovative materials including nanocomposites, nanoparticles and antimicrobial nanomaterials, which have substantially improved the performance and outcomes of dental treatments. The new generation of nanocomposites, for instance, offers improved colour match to the natural dentition along with enhanced wear resistance. Similarly, antimicrobial nanomaterials are being investigated to combat bacterial infections within the oral cavity, aiming not only to treat but also to prevent disease.
Moreover, the specific application of these materials extends to a range of dental procedures, from fillings and prosthetics to bone regeneration and endodontic therapy. Researchers and clinicians are exploring the potential for these nanotechnology-based materials to mimic the natural biomechanical properties of dental tissues such as enamel, offering a personalised and biomimetic approach to oral health care solutions. As the field continues to progress, the increased understanding of interactions between dental materials at the nano-level and the biological environment holds promise for further breakthroughs in dental material science.

Comprehensive research into the biocompatibility and toxicological profiles of nano-enhanced dental materials is critical. The focus remains on ensuring these materials do not adversely affect human health or lead to issues such as oral cancer, while maintaining the required antibacterial activity.
Clinical Applications and Treatments
Nanotechnology substantially advances clinical outcomes in dentistry by enhancing materials and treatment methods, promising improved oral health and more effective dental practice.
Nanotechnology in Dental Restorative Procedures
Nicknamed ‘nanodentistry’, the integration of nanotechnology within restorative dentistry has led to the development of superior dental restorative materials. Incorporating nano-sized fillers into composites results in restoratives that not only aesthetically blend with natural tooth structure but also possess increased strength and wear resistance. Ceramics, particularly zirconia, are engineered at the nanoscale to improve their mechanical properties, resulting in prosthodontics and orthodontic implements that are both durable and visually pleasing.

Enhancement of Dental Prophylaxis
Nanotechnology contributes to advancing prophylactic treatments in dental applications by combating dental biofilms, a significant factor in periodontal disease and caries. Antimicrobial biomaterials have been designed at the nanoscale to disrupt biofilms and reduce the incidence of oral infections. Dental products such as toothpastes and mouthwashes incorporate nanoparticles to enhance their antimicrobial efficacy without compromising patient safety.

Nanotechnology for Diagnostics and Pathology
Nanotechnology has revolutionised the field of dental diagnostics and pathology, offering precise early detection methods and non-invasive diagnostic techniques.
Early Detection and Diagnosis in Dental Pathologies
Nanotechnology is pivotal in the early detection of oral diseases, which is fundamental for successful treatment outcomes. One key area is the diagnosis of oropharyngeal carcinoma, where nanoscale devices can identify cancer cells at much earlier stages than traditional methods. Similarly, oral squamous cell carcinoma, the most common form of oral cancer, benefits from nanoscale diagnostic tools that can detect abnormal cells earlier and more accurately.
Antimicrobial nanomaterials are utilised to target Streptococcus mutans, the primary bacteria responsible for dental caries, and their ability to form oral biofilm. Nanocoatings applied to dental surfaces can help inhibit biofilm formation, thereby preventing pathologies before they can cause damage.
Non-Invasive Techniques in Oral Health Monitoring
In the realm of oral health, nanotechnology offers non-invasive techniques that greatly enhance patient comfort and compliance. Nanodiagnostic devices can detect markers of disease in saliva, providing a pain-free alternative to traditional biopsy and tissue sampling methods. The presence of metal/metal oxide nanoparticles in oral biofilm can serve as contrast agents for advanced imaging techniques, allowing for detailed visualisation without invasive procedures.
The development of nanosensors has also enabled the real-time monitoring of conditions, allowing for immediate intervention. These sensors, functioning at a nanoscale level, can detect minute changes in the oral environment, including pH shifts and bacterial activity, often signalling the onset of disease.
Future Perspectives in Nanodentistry
Nanodentistry is poised to revolutionise the future of dental care with groundbreaking materials and methodologies, though it also raises salient safety and ethical queries.
Emerging Trends in Nanotechnology Research
Recent advancements in nanotechnology research have significantly influenced the development of dental nanocomposites. These materials, composed of nanoparticles, offer superior aesthetics, mechanical properties, and durability compared to conventional composites.
