Abstract
A high quality direct radiographic film is useful for dental care. The film contains relatively high silver coverage preferably coated on both sides of the support. It also contains sufficient silver halide desensitizer to reduce silver halide sensitivity to X-radiation by at least 0.02 log E. The combination of silver and desensitizer coverages provides sufficiently high photographic speed, excellent image quality and increased stability to background radiation sources.
