also used in dentifrices and mouth rinses to
provide antimicrobial activity.6 Its limited
shelf life created concerns for patients, but
in recent years activated chlorine dioxide
stored in dual chambers and mixed by the
patient immediately before use as a rinse
has overcome this problem.7
* Peroxides at low concentrations
(≤ 3 percent) have long been recommended
to reduce plaque and gingivitis with a
good safety record. Disruption of the
biofi lm occurs after exposure to hydrogen
peroxide-likely a combination of chemical
and mechanical processes. The problem that
researchers identified in using peroxide
for the treatment of periodontal disease
is mechanical access to the pocket.8 The
rinsing and brushing just doesn't reach
deep enough for patients with pocketing
greater than 3mm.
The challenge is not just getting medication deep into periodontal pockets, but also
holding it there long enough for therapeutic

effect. Sealed prescription trays provide effective delivery deep into periodontal pockets
(up to 9mm) for concentrations of peroxide
as low as 1.7 percent. The oxygenation of the
periodontal pockets via a daily 10-minute
tray application is hypothesized to modify the
microenvironment of the periodontal pocket
to modify biofilm regrowth.9 Chlorine-based
products have not been used in the tray
because of concerns for taste, staining and
gingival irritation.

Prescription tray therapy
Clinical trials have shown that use of
hydrogen peroxide, delivered in a sealed
prescription tray as an adjunct to scaling,
reduces bleeding and pocket depth better
than scaling alone.10 Evaluations of refractory
maintenance patients from a periodontal
office tracked patients for up to five years
demonstrating that the addition of sealed
prescription tray therapy helped reduce
inflammation by 75 percent more than
