Periodontal assessment
BPE explained: sextants, scores 0 to 4, and what each one commits you to

Blog
Explainers for the bits that catch people out
The topics that come up again and again in the Knowledge Test, written out properly — with the reasoning, not just the answer.
Dental materials
Alginate impressions: tray try-in, mixing, seating and what happens after removal
Tray selection, mixing, seating and disinfecting an alginate impression, with the UK scope and infection-control points a US video leaves out.
Airway management
Nasopharyngeal airway insertion: who tolerates it, when to hesitate, and how it goes in
Why the NPA suits the semi-conscious, clenched or facially injured patient, what base of skull fracture changes, and how sizing and insertion are examined.
NEBDN
NEBDN workbook exam revision: how to approach instruments, materials and scenarios
Revise NEBDN image-selection scenarios confidently, from instruments and materials to radiography and medical emergencies.
Airway management
Oropharyngeal airway insertion: sizing, the 180-degree twist, and why the unconscious patient only
How to size a Guedel airway, insert it in an adult and an infant, and why a gag reflex means you have chosen the wrong adjunct.
Orthodontic Dental Nursing
Class I, II and III: reading an incisor classification from the cingulum plateau
The incisor classification is one landmark and one question: where does the lower incisal edge meet the upper incisor? Get that straight and the rest follows.
Dental Radiography
IR(ME)R duty holders: who justifies, who authorises, who presses the button
Referrer, practitioner, operator, employer — what each IR(ME)R 2017 duty holder is responsible for, and why exam questions hinge on telling them apart.
Dental Sedation Nursing
Pulse oximetry in dental sedation: what it measures, and when it lies
Cold hands, a sensor taped too tight, a reading that holds steady. What a pulse oximeter tells you during conscious sedation — and what it does not.
Dental Radiography
The two-point image quality scale: why 'excellent' is no longer a rating
The 2020 guidance replaced the three-point quality scale with A and N: acceptable or not. If you were taught the three-point version, unlearn it.
Assessment and Diagnosis
BPE codes explained: what 0 to 4 actually mean
The Basic Periodontal Examination scale, sextant by sextant — what each code records, where the 3.5 mm and 5.5 mm thresholds sit, and what the asterisk means.
Professional Practice
Decontamination: cleaning, disinfection and sterilisation are not the same thing
The three terms the Knowledge Test keeps testing, why instruments move one way through a decontamination room, and what the cycle record is actually for.
CPD
Enhanced CPD for dental nurses: hours, outcomes and what to record
50 hours, a five-year cycle, four development outcomes and two statements — the GDC enhanced CPD scheme, with the numbers that get examined.
Medical emergencies
Medical emergencies in the dental practice: recognition first, then response
Why the exam tests recognition and sequence rather than treatment detail, how DRABC structures the first minute, and what preparedness really requires.
Exam technique
How to revise for the NEBDN Knowledge Test
What the Knowledge Test asks, why re-reading your notes does not work, and a revision approach built around retrieval practice rather than recognition.
