The average dose of radiation associated with one periapical (PA) radiograph is approximately 100-150 mR (milliroentgens). This range is supported by various studies that assess the radiation exposure of dental radiographs and take into consideration factors such as the type of film used, the exposure settings, and the patient's size.

Periapical radiographs specifically target the tooth and surrounding bone structures, allowing for a detailed view with relatively low radiation exposure compared to other imaging techniques. Advances in digital radiography have further reduced the radiation dose associated with dental imaging, making it safer for both patients and practitioners.

Understanding this dose is crucial for dental professionals as it aids in risk assessment and informed consent discussions with patients regarding the necessity and safety of dental radiographs. Maintaining awareness of radiation doses is an essential aspect of practicing radiation safety in dentistry, ensuring that exposures are kept as low as reasonably achievable (ALARA principle).
