A significant number of Americans
do not visit the dentist for regular checkups
because they are too fearful or suffer from dental
anxiety. Sedation dentistry offers an excellent way
to provide a safe, anxiety-free, dental experience
to those who are afraid of the dentist.
Sedation dentistry is often
mistakenly thought to induce sleep. In fact, most
sedatives allow the patient to stay awake during the
procedure. Sleepiness is a side effect of some
medications, but nitrous oxide, oral conscious
sedation and IV sedation only work to calm anxiety
throughout the dental visit.
Sedation dentistry is popular
because most sedatives can be taken by mouth,
meaning no injections, no anxiety and no pain. Some
sedatives work so effectively that even the smells
and details of the procedure cannot be recalled
afterwards. Safety and compliance are two important
aspects of treatments, so sedation dentistry offers
both the individual and the dentist the best
alternative.
Whatever the form of sedative, it
is essential to be accompanied by a caregiver.
Sometimes, sedatives are provided the night before
the dental visit, which means that driving to or
from the appointment is not advisable.
Here are some advantages
associated with sedation dentistry:
What kinds of
sedatives are available?
The most popular types of dental
sedatives are nitrous oxide, oral conscious
sedation, and IV sedation. Different levels of
sedation (mild, moderate and deep) can be utilized
depending on individual needs. Before administering
any sedative, the dentist must analyze the full
medical history of the patient, as well as taking
note of any current medications.
Here is an overview of some of
the most common types of dental sedatives:
Nitrous Oxide
Nitrous oxide, or “laughing gas,”
is used as a mild sedative. It is delivered through
a nose hood, and is administered throughout the
entire procedure. Nitrous oxide elevates the
general mood and can evoke a general sense of
well-being. Most importantly, it relieves anxiety
and reduces pain during the procedure. In addition,
some tingling and numbness may be felt. There are
few side effects associated with nitrous oxide, and
it has been safely used in dentistry for many years.
IV Sedation
Intravenous sedation is a
moderate type of sedation. Patients who have
previously experienced IV sedation often report
feeling like they slept through the entire
procedure. Generally, IV sedation is used for
shorter treatments. It is administered via direct
injection into the bloodstream, which means the
effects are immediate. Sometimes patients feel
groggy and sleepy when the IV sedatives are
withdrawn. This is why it is important to bring a
designated driver for the drive home.
Oral Conscious Sedation
Oral conscious sedation is an
excellent choice for people who fear needles. Oral
medication is provided prior to treatment in order
to induce a moderate state of sedation. Though oral
sedatives do not cause sleep, they usually dull the
senses. This means that most patients cannot
remember the pain, smells or noises associated with
the procedure. Usually, a dose of medication is
taken prior to the appointment, and then topped up
during the procedure as required.
What types of drugs
are used in oral conscious sedation?
Most of the drugs used in
sedation dentistry are classified as
benzodiazepines. Benzodiazepines reduce anxiety,
muscle spasms, insomnia and seizures. Each
medication has a different half-life, meaning that
the effects last for varying amounts of time. The
estimated length of the procedure determines which
type of drug is going to be most effective.
Here are some of the most common
drugs used in oral conscious sedation:
Valium®
– This sedative has amnesic properties and a long
half-life. It is usually used for time-consuming,
complex procedures.
Halcion®
– Usually used to treat insomnia, Halcion is an
effective sedative with amnesic properties. A short
half-life makes this sedative useful for shorter
procedures.
Ativan®
– This sedative is best known for reducing anxiety.
It has amnesic properties and a medium half-life.
Ativan is typically used for treatments shorter than
two hours.
Versed®
– This sedative has the shortest half-life and is
therefore less commonly used. It alleviates anxiety
in much the same way as nitrous oxide, and is used
for visits that will take less than 30 minutes.
