Why this spec matters
A Japan Dental Technician (歯科技工士) is a national license under the 1955 Dental Technicians Act. The role is a technical craft profession: under instruction from a dentist, the technician fabricates dentures, orthodontic appliances, and crown-and-bridge prosthetics. Unlike the Dental Hygienist (1948 Dental Hygienists Act), who performs chairside preventive care and patient guidance, the Dental Technician almost never touches patients and works in a lab or in-clinic technical room. The exam photo spec — 60mm tall × 40mm wide — is identical to the nurse, pharmacist, and Dental Hygienist exams. In addition, the Dental Technician exam has its own rules: the photo must be glued onto an official paper mount issued by the Japan Dental Medical Promotion Foundation, and an identity check ("the photo is indeed the applicant") must be performed by the dental technician school or training facility the applicant currently attends or has graduated from, or by the Foundation itself. Although the same Foundation also issues the mount for the Dental Hygienist exam, the two exams are entirely separate licenses with separate applications and separate identity checks — photos and mounts cannot be reused between them.
