Instructions for vital tooth whitening:
- Determine and record pre-operative shade.
- Clean teeth with ONLY a flour based pumice
- Place cheek retractors and then cover exposed lip surface with petroleum gel
- Dry teeth and apply Gingival Barrier to both arches, slightly overlapping enamel and interproximal spaces
- Light cure in a fanning motion for 10-20 seconds until Gingival Barrier is cured
- Firmly attach a mixing nozzle to the Pola Office+ syringe away from patient. Dispense a small amount of gel on to a mixing pad until a uniform gel is extruded
- Using the nozzle as a guide, directly apply a thin layer of gel to all teeth undergoing treatment. A thin layer will help prevent the gel from running.
NOTE: It is best not to lift the nozzle when moving from tooth to tooth. Use a continuous motion - Leave gel on for 8 minutes (Optional: a curing light may be used at this stage, please refer to light manufacturer’s recommendations)
- Suction off using a surgical aspirator tip. Note: It is normal for a residue layer of gel to remain on the surface of the teeth
- Repeat steps 7-9 three times (optional 4 times)
- After the last application, suction all the gel off, then wash and apply suction
- Remove Gingival Barrier by lifting it from one end
- Record the final shade.
Tips for non-vital tooth whitening:
- Isolate tooth effectively
- Protect oral mucosa to prevent chemical burns
- Verify adequate endodontic obturation
- Use protective barrier to prevent peroxide from reaching the periodontal ligament
- Avoid acid etching as periodontal ligament irritation may result
- Advise the patient that a whitened non-vital tooth will not look the same as a vital tooth
- Recall patients periodically to examine the whitened teeth (clinically & radiographically).
Instructions for NON-vital tooth whitening:
- Determine and record pre-operative shade.
- Isolate tooth/teeth undergoing whitening using a rubber dam. Ensure the dam fits tightly at the cervical margin.
Note: If a rubber dam is not used, cover approximately half of the adjacent vital teeth with 3-4mm thick layer of Gingival Barrier to insulate from heat discomfort of the curing light. This is done when one tooth is being whitened non-vitally
- Open lingual access to pulp chamber and remove all composite, base material and gutta percha 2-3 mm apical to the CE junction. Place a glass ionomer/zinc phosphate base, at least 1 mm thick to ensure a barrier between the “sealed” root canal and whitening gel
- Place the Pola Office+ gel into the opened pulp chamber and onto the labial surface
- Leave gel on/in for 8 min (Optional: curing light may be used at this stage, please refer to light manufacturer’s recommendations)
NOTE: If using a curing light and treating inner and outer surfaces, 2 curing lights can be used (one on each side of tooth) to activate Pola Office+ - Suction off the gel
- Repeat steps 4-6 until desired shade is achieved
- After the last application, suction and wash the gel off
- Record the final shade.
