Nanoparticles (NPs) are insoluble particles with a diameter of fewer than 100 nanometers. Two main methods have been utilized in orthodontic therapy to avoid microbial adherence or enamel demineralization. Certain NPs are included in orthodontic adhesives or acrylic resins (fluorohydroxyapatite, fluorapatite, hydroxyapatite, SiO2, TiO2, silver, nanofillers), and NPs (i.e., a thin layer of nitrogen-doped TiO2 on the bracket surfaces) are coated on the surfaces of orthodontic equipment. Although using NPs in orthodontics may open up modern facilities, prior research looked at antibacterial or physical characteristics for a limited period of time, ranging from one day to several weeks, and the limits of in vitro studies must be understood. The long-term effectiveness of nanotechnology-based orthodontic materials has not yet been conclusively confirmed and needs further study, as well as potential safety concerns (toxic effects) associated with NP size.

Background: The oral cavity, which stretches from the lips to the oropharynx, is the initial portion of the digestive system. Materials and Method: Twenty-eight separate oral soft tissue surgeries were performed, fourteen with a 940 nm Diode laser with an output power of 1W and the other fourteen with a scalpel. Results: Although there was no difference in healing between the two groups, patients who were operated on with a laser felt more comfortable than those who were operated on with a conventional manner.
