I. Description:
Opalescence® Xtra® Boost™ is a 38% hydrogen peroxide power bleaching gel. The distinctive syringe to syringe mixing process ensures fresh product for each application. One barrel contains a unique chemically activated chemistry. The other contains hydrogen peroxide. When mixed, Opalescence Xtra Boost is ready for use. OpalDam® is a unique, light-reflective, passively adhesive(sealing) light cured resin. It’s methacrylate base is designed with adequate strength to maintain a barrier, yet it easily removes from embrasures and undercuts.

Vital Bleaching with OpalDam Use Opalescence Xtra Boost alone or in conjunction with the dentist-supervised Opalescence® Take-Home Bleaching System. Our experience showsthat most treated teeth continue to whiten 12-24 hours after treatment. OpalDam is used to protect soft tissue adjacent to the teeth during in-office bleaching, microabrasion, etc.

embrasures, onto cingulums, and on adjacent gingiva. Light cure as directed below in section “d.”

III. Preliminary Procedures:
Fig. 1 Express OpalDam resin to build a 4-6mm by 1.5-2mm thick strip onto gingiva. Lapapproximately 0.5mm onto enamel. Extend resin beyond the last tooth to be bleached. Where open embrasure(s) exist, express resin through the opening onto lingual, filling embrasure space completely. This will protect interdental papilla and lingual gingival tissue. Resin buttons extending through gingival embrasures add retention to OpalDam barrier.

II. Indications:

Power bleaching is forin-office use only. It is used for dentist-applied bleaching of one or more teeth, parts of a tooth, and/or for accelerated chairside whitening techniques. Opalescence Xtra Boost is also used on nonvital teeth, including intracoronal bleaching in office. Opalescence Xtra Boost is an alternative, conservative method for treating dark, discolored teeth (compared to crowns, veneers, etc.). Thisincludes discolorations caused by congenital, systemic, metabolic, pharmacological, traumatic or iatrogenic factors such as dental fluorosis, jaundice, tetracycline and adult minocycline stains, porphyria, trauma, and erythroblastosis fetalis. Because restorative materials will not whiten, we recommend whitening teeth before esthetic restorative placement (wait two weeks after bleaching procedures beforeplacing adhesive restorations). Bleaching problematic teeth to a more natural shade will optimize shade matching.

1. Remove any calculus or extrinsic stains before the bleaching appointment. This is ideally done prior to the bleaching appointment to prevent sulcular seepage at time of OpalDam application and bleaching treatment. 2. Determine and record shade before bleaching. 3. Shieldpatient’s and clinician’s eyes with protective eyewear with side shields during mixing and applying. 4. Place Ultradent IsoBlock® (Fig. 4).

Fig. 3 Apply Opalescence Xtra Boost 0.5 to 1.0mm thick layer. Place the gel on the labial surfaces. Extend slightly onto incisal/occlusal edge.

IV. Isolation:
I s o l at teeth to be bleached with OpalDam light cured resin (Fig. 1) e or with conventional rubberdam (we recommend powder-free DermaDam®) used with OraSeal® Caulking for maximum rubber dam seal. If bleaching only one or a few teeth, OpalDam is the gingival barrier of choice. 1. Isolation Procedure Using OpalDam: a. Remove luer lock cap and attach a disposable Micro 20 gauge tip securely onto OpalDam syringe. b. Place self-supporting plastic cheek retractors. Completely rinse and air dry teeth,paying special attention to the gingival third.
Fig. 4 Place Ultradent’s IsoBlock.

Before treatment. Fig. 2 Cure resin with a quality curing light 20 seconds per light guide width. Clean teeth with prophy paste to remove any excess resin film. Use caution not to dislodge cured OpalDam barrier.
