A 'Fissure Sealant' is a Band 1 surface application as a primary preventive treatment item. A fissure sealant (Band 1) should not be confused with the term 'Sealant Restoration' which is appropriate to Band 2a.
A 'fissure sealant' is where fissure sealant alone is used.
A 'sealant restoration' is a filling where tooth tissue has been removed due to caries and restored with composite or glass ionomer and sealed with a fissure sealant.
Bitewing radiographs are usually considered a prerequisite to sealant restorations and diagnosis of treatment need.
As with any Band 1 or Band 2 claim, an examination and completion of treatment necessary to secure the oral health of the patient (that the patient is willing to undergo) is a requirement.
