discuss the advantages/disadvantages and indications for the placement of fissure seals

Advantages of Fissure Sealants:

1. Prevention of Tooth Decay: Fissure sealants are effective in preventing tooth decay. They provide a protective layer that prevents food particles and bacteria from accumulating in the deep grooves of teeth.

2. Non-Invasive Procedure: The application of fissure sealants is a non-invasive procedure. It does not require any drilling or removal of tooth structure.

3. Cost-Effective: In the long run, fissure sealants can be cost-effective. They can prevent the need for more expensive restorative treatments in the future.

Disadvantages of Fissure Sealants:

1. Not Permanent: Fissure sealants are not a permanent solution. They can wear off over time and may need to be reapplied.

2. Not Suitable for All Teeth: Fissure sealants are not suitable for all teeth. They are typically applied to the back teeth (molars and premolars), which have deep grooves.

3. Risk of Sealant Failure: If the sealant is not properly applied, it can fail to provide the intended protection. This can lead to decay under the sealant.

Indications for the Placement of Fissure Sealants:

1. Deep Grooves and Fissures: Teeth with deep grooves and fissures are more prone to decay and are good candidates for fissure sealants.

2. High Risk of Tooth Decay: Individuals who are at a high risk of tooth decay may benefit from fissure sealants. This includes children and teenagers, individuals with a history of tooth decay, and individuals with a high intake of sugary foods and drinks.

3. Newly Erupted Permanent Teeth: Fissure sealants are often applied to newly erupted permanent teeth in children to protect them from decay.
