At Lysaght Dental we offer you the very latest in digital radiography. This means that when radiographs are taken you can be assured that you are getting the minimal dose of radiation possible with current technology. We further protect you with the use of a rectangle collimator which reduces the dose by 40% compared to a standard x-ray. It is common for both tooth decay and periodontal disease to be impossible to detect during a clinical exam. Radiographic evaluation of the dental and periodontal tissues is a critical segment of the comprehensive oral examination.
