Which sensor size for an anterior periapical
The RVG sources say periapical. They do not split anterior from posterior, so this page does not assign a size to anterior films.

X-ray equipment must be bought, installed, and registered per state radiation rules and the manufacturer's requirements.
- RVG 6200 Size 1: 22.2 × 29.6 mm
- RVG 6200 Size 2: 26.6 × 35.5 mm
What is published
SM846 lists size 1 for regular periapical and retro-coronary procedures, and size 2 for bitewings and peri-apical procedures. The product page shows a periapical example labeled size 1.
What is not published
Neither page says anterior, posterior, or a separate size for front teeth. Choosing size 1 for every anterior periapical would be an added claim. This page does not add it.
Active areas
Size 1 is 22.2 × 29.6 mm. Size 2 is 26.6 × 35.5 mm. Both use a 19 micron pixel dimension on the product page.

Questions
- Is size 1 the anterior sensor?
- The sources do not say that. They say periapical for both sizes, with different wording.
- Where is the word anterior?
- It is the search. It is not a sentence on the RVG product page or in the SM846 use table.
- What should you follow?
- The instructions for use and the positioning device the manual or the dentist specifies.
