Situations with and without Clinical Site Restoration
A – Treatment Site without restoring tooth
- Using a non-fluoride prophylaxis paste in a rubber cup, clean the tooth/teeth to be treated and abutting teeth.
- Assess condition of teeth. Only teeth with sound dentine and enamel should be treated.
- Isolate area to be treated with cotton rolls or rubber dam or protect the gingival tissue around the affected tooth with petroleum jelly.
- Apply 37% phosphoric acid, e.g. Super Etch (SDI Limited), to site for 5 seconds - wash then dry, do not desiccate.
- Riva Star Step 1: Using the silver brush provided, pierce through the foil of the silver capsule and carefully apply solution to treatment site only.
- Riva Star Step 2: Immediately after, use green brush provided, pierce through the foil of the green capsule and apply a generous amount of the solution to treatment site. Apply same solution to any other tooth surfaces that may have come into contact with the solution from the Riva Star Step 1 capsule (silver capsule).
Note: Treatment surface initially appears creamy white, keep applying solution from Riva Star Step 2 capsule (green capsule) until it turns clear.
- Discard used capsules and brushes in accordance with local regulations.
- Blot dry or if clinical situation permits, wash thoroughly with water for at least 10 seconds and air dry, do not desiccate.
- Reschedule patient to return for permanent restoration procedure if required. For deciduous teeth wait for teeth to exfoliate.
B – Restoring with Self Cure (Auto Cure) Glass Ionomer Cement
- Using a non-fluoride prophylaxis paste in a rubber cup, clean the tooth/teeth to be treated and abutting teeth.
- Assess condition of teeth. Only teeth with sound dentine and enamel should be treated.
- Isolate area to be treated with cotton rolls or rubber dam or protect the gingival tissue around the affected tooth with petroleum jelly.
- Apply 37% phosphoric acid, e.g. Super Etch (SDI Limited), to site for 5 seconds - wash then dry, do not desiccate
- Riva Star Step 1: Using the silver brush provided, pierce through the foil of the silver capsule and carefully apply solution to treatment site only.
- Riva Star Step 2: Immediately after, use green brush provided, pierce through the foil of the green capsule and apply a generous amount of the solution to treatment site. Apply same solution to any other tooth surfaces that may have come into contact with the solution from the Riva Star Step 1 capsule (silver capsule).
Note: Treatment surface initially appears creamy white, keep applying solution from Riva Star Step 2 capsule (green capsule) until it turns clear.
- Discard used capsules and brushes in accordance with local regulations.
- Blot dry or if clinical situation permits, wash thoroughly with water for at least 10 seconds and air dry, do not desiccate.
- If required, place suitable matrix system to tooth
- Place SC GIC e.g. Riva Self Cure (SDI Limited) into cavity preparation according to the manufacturer’s instruction for use
- Contour the restoration prior to occlusal adjustment.
- Polish to complete restoration
- Remove all protective/isolation materials used in the mouth.
C – Restoring tooth with a composite or Resign Modified Glass Ionomer Cement (RMGIC)
- Using a non-fluoride prophylaxis paste in a rubber cup, clean the tooth/teeth to be treated and abutting teeth.
- Assess condition of teeth. Only teeth with sound dentine and enamel should be treated.
- Apply 37% phosphoric acid, e.g. Super Etch (SDI Limited), to site for 5 seconds - wash then dry, do not desiccate
- Riva Star Step 1: Using the silver brush provided, pierce through the foil of the silver capsule and carefully apply solution to treatment site only.
- Riva Star Step 2: Immediately after, use green brush provided, pierce through the foil of the green capsule and apply a generous amount of the solution to treatment site. Apply same solution to any other tooth surfaces that may have come into contact with the solution from the Riva Star Step 1 capsule (silver capsule).
Note: Treatment surface initially appears creamy white, keep applying solution from Riva Star Step 2 capsule (green capsule) until it turns clear. (in some cases, a residual yellowish matt surface may remain).
- Discard used capsules and brushes in accordance with local regulations.
- Wash thoroughly with water for at least 10 seconds and air dry, do not desiccate.
- If required, place suitable matrix system to tooth
- Place SC GIC e.g. Riva Self Cure (SDI Limited) into cavity preparation up to level of DEJ
- Prior to setting of GIC, prepare resin bonding agent e.g. Riva Bond LC (SDI Limited) and apply to GIC surface using a micro brush, condensing GIC at the same time.
- Place composite material e.g. Aura Bulk Fill (SDI Limited) or RMGIC e.g. Riva Light Cure (SDI Limited) and condense cavity to slightly overfill the preparation.
- Light cure the restoration for manufactures recommended time (heat produced from setting will help set the GIC liner).
- Contour the restoration prior to occlusal adjustment.
- Polish to complete restoration.
- Remove all protective/isolation materials used in the mouth.
