A structure for a new-patient or full routine examination: history, a complete soft and hard tissue check, periodontal screening, radiographs and a treatment plan. Use it as a checklist for what a thorough exam note should cover, then write your own findings under each heading.
GDC standard 4.1 expects a patient's clinical record to be made as the appointment happens, and to be accurate and complete.
Assist records the appointment and drafts a note in this structure for the dentist to review and sign off. It writes up what was said in the room, and you check every line before it goes in the record.
