Aim & Objective: Nanotechnology is a field growing as a major influencer in the health community in recent times. In dentistry, particularly Periodontics, nanotechnology promises great strides in diagnostics, therapeutic strategies and treatment efficacy. Using the specific features of nanomaterials, which involve, their small size, ability to cover large areas while occupying very little space and the chemical attributes that can be changed very easily by the scientists, are some of the innovative approaches towards nanomaterials being used to handle the multifaceted nature of periodontal diseases. This essay examines how nanotechnology is used in periodontology at the cutting edge level with emphasis on how it could redefine preventive practices, diagnostic procedures and curative interventions resulting in positive oral health outcomes. Material & Method: The review adopts a systematic approach to scrutinize the current literature on the employment of nanotechnology in periodontics. A rigorous search through reputable databases identified peer-reviewed articles that met established inclusion criteria. The use of terms such as nanomaterials in periodontal diagnostics, treatments and therapeutics was targeted for data extraction. The study reviews the incorporation of nanotechnology into periodontology with the aim of giving useful information on this new technology. Result: Nanotechnology is widely applied in periodontics and this can be seen from all the literatures. Nanomaterials help in diagnosis, deliver drugs to target cells, and improve tissue repair. Such a discovery points towards the probability of nanotechnology revolutionizing the dental care.
