Abstract

Background: Dental tissue that has been irradiated with a laser undergoes morphological and chemical changes. Because the magnitude of these changes is influenced by the absorption qualities of the tissue, it is possible that these alterations will vary depending on the kind of laser used and the dental tissue. Objective: The purpose of this research was to evaluate the mineral content of dentin irradiated with CO2 10600nm, Diode 980nm and Er:Cr: YSGG 2780nm. Material and method: One hundred extracted molars were utilised for the study, and the samples were split into five groups. Next, the enamel was scraped from the dentin surface using a standard bur while abundant coolant was applied. A low-speed diamond stone was used to prepare the teeth, resulting in the creation of two slabs for each tooth. The dentine of samples were irradiated to .5 watt of co2, diode, Er:Cr: YSGG lasers with nano ZnO-HA and without. Calcium (Ca) and phosphorous (P) were measured and analysed using a Scanning Electron Microscope (SEM) in conjunction with Energy Dispersive X-ray (EDX).
