The dental unit is an essential component of any dental clinic, providing a comfortable seating position for patients. It typically includes a dental chair for patient positioning during treatment, a tool holder with various instruments and machines used for dental examinations and treatments, a light for illuminating the area of interest, a sink, and a suction system. Additionally, the unit may have X-ray imaging capabilities for capturing images of the teeth, which dentists use to assess oral health. These X-rays use a low dose of radiation to capture internal images of the teeth and gums
