Question

What is the function of potassium iodide in SDF

Answer 1

reduces staining

Answer 2

* silver * water * fluoride * ammonia

Answer 3

* helps kill bacteria

Answer 4

* Provides a liquid base for the mixture

Answer 5

* Helps your teeth rebuild the materials they’re made of (known as remineralisation)

Answer 6

Helps the solution remain concentrated so that it is maximally effective against cavity resonance

Answer 7

black may temporarily stain soft tissues brown for 1-3 weeks

Answer 8

* Rarely, it can cause a chemical burn to the gingivae

Answer 9

* Asymptomatic cavitated dentine carious lesions in primary teeth * Lesions that can be made cleansable * Dentinal lesions that are non-restorable * Root surface caries * Promoting the arrest and remineralisation of active carious lesions * Active dentinal lesions * Pre-cooperative children * Permanent teeth with MIH (blocking dentinal tubules may reduce sensitivity)

Answer 10

* Signs/symptoms of irreversible pulpitis, or dental abscess or sinus * Radiographic peri-radicular radiolucency or signs of pulpal involvement * Infection/pain from pulpal origin or food packing * Allergy to any ingredient inclusive of silver and other heavy metals * Active ulceration, mucositis or stomatitis * Pregnant or breastfeeding * Patients undergoing thyroid gland therapy or on thyroid medication (if potassium iodide used)

Answer 11

Apply petroleum jelly to the soft tissues including the lips if possible Protect the gingiva using petroleum jelly and cotton wool rolls or Riva Star gingival barrier * Ensure teeth are clean and free of debris * Dry teeth using a cotton wool roll or gauze * Use the silver brush or another micro-brush to pierce the silver capsule * Carefully apply the solution from the silver capsule (silver diamine fluoride) to the treatment site with the silver brush, a micro brush or other single use applicator. This should be left to dry for at least 1 minute, ideally 3 minutes. * If a decision has been made with the family to use potassium iodide then follow 7 * 7a) pierce the foil of the green capsule * 7b) apply solution from green capsule (potassium iodide) to treatment site, with the green brush, a micro brush or other single use applicator. Continue application until the creamy white solution present on the lesion turns clean * Blot teeth dry using a cotton wool roll, gauze or fresh single use micro-brush * Remove gingival barrier if used

Answer 12

2-4 weeks after first application

Answer 13

* hard, darkened lesion.

Answer 14

* Slows down the development of decay by stopping demineralization * Makes enamel more resistance to acid attack and speeds up remineralization – bonds with calcium and phosphate to create fluorapatite * Can stop bacterial metabolism at high concentrations to produce less acid

Answer 15

* Provides extra protection against tooth decay when used in addition to brushing * Pale yellow gel that sets quickly when applied to childrens teeth using a soft brush

Answer 16

4 times a year

Answer 17

* Allergy to colophony * Hospitalized with severe asthma in past 12 months * Ulcerative gingivitis * Residual varnish is visible * Child has had varnish applied in the past 24 hours

Answer 18

* Eat soft foods for rest of the day to reduce chewing * Children should not brush their teeth that evening but should continue to brush twice a day with fluoride toothpaste from the following morning (this is debatable - clinicians would probably disagree but this is whats on childsmile)

Answer 19

* bis-GMA with dimethacrylaet monomer to make the sealant easy to flow
