In this article we will discuss about Nano Dentistry:- 1. Meaning of Nano Dentistry 2. Advantages of Nano Dentistry 3. Disadvantages.
Meaning of Nano Dentistry:
Extending nanotechnology into the field of dentistry thereby makes Nano dentistry an emerging field with significant potential to yield new generation of clinical tools, materials and devices for oral health care. Nano dentistry is said to be the future of dentistry where all procedures are to be performed using Nano robots that may become a replacement to the present day dental assistants, technicians & hygienists.
The discovery of Nano dental materials such as Nano powders and Nano composites reinforced with Nano fillers are the most rapidly developing group of materials with excellent prospective for application in the field of dentistry.
Nanostructured yttrium stabilized zirconium oxide ceramics is widely used for fabrication of crowns, bridges, inlays and other dental elements for which high strength, durability and better aesthetics are required. Nanoparticles of varying composition and chemistry have been engineered to prevent the biofilm from attaching to the tooth’s surface which is the prime cause for development of plaque and calculus.
Some nanomaterial’s have also been developed to help with the remineralisation of the teeth after significant decay. Precisely, it brings forth a new era of local anesthesia’s, dentifrices (tooth paste), better treatment modalities in the management of gum problems, dental caries, tooth hypersensitivity and oral cancer by the usage of morphological, biophysical and biochemical properties of the oral cavity.
The diagnosis of the associated problems will become easier due to smaller diagnostic machinery and Nano-devices with ultimate correctness in the results within shortest span of time. It also promises to reduce the span of cosmetic procedures with faster healing and improved aesthetics.
The painful procedures, mortality and morbidity rates thus associated will be reduced spontaneously in the future. With such possible innovations any disease can be relevantly treated at any stage with great efficacy.
Advantages of Nano Dentistry:
1. Superior hardness, flexural strength, modulus of elasticity, translucency, durability of Nano-dental materials and excellent handling properties of all Nano-dental products.
2. Faster and accurate diagnosis of oral diseases with small diagnostic machinery.
3. Reduced span of treatment procedures with faster healing properties.
4. Reduced mortality and morbidity rates thus associated with certain oral diseases.
5. Better aesthetics.
6. Reduced frequency of visits to the dental clinics for patients and less fatigue for the practitioners.
7. Obvious better outcome of the treatment procedures.
8. Economical.
Disadvantages of Nano Dentistry:
1. Numerous ethical issues to deal with (social acceptance is necessary).
2. Toxicity thus associated with the nanoparticles is harmful to human beings as well as to the environment.
3. Subsequent irretrievable genetic information loss that was essential for better prospects of Nano-dentistry and nanotechnology in general.
