VERIFIABLE CPD PAPER
• The Mental Capacity Act 2005 sets out a
legal framework on how to act where an
adult is not considered to be competent to
give informed consent.
• Some conditions impact on the consent
process and may lead to invalid consent
if adjustments are not made to the way in
which information is given and obtained.
• Physical intervention may rarely be required
in the dental setting and must be carried
out within a legal and ethical framework.
IN BRIEF
PRACTICE
This article considers what is meant by informed consent and the implications of the Mental Capacity Act in obtaining
consent from vulnerable adults. It explores a number of conditions which impact on this task, namely dyslexia, literacy
problems and learning disability. The focus on encouraging and facilitating autonomy and the use of the appropriate level
of language in the consent giving process ensures that consent is valid. The use of appropriate methods to facilitate com-
munication with individuals in order to be able to assess capacity and ensure that any treatment options that are chosen
on their behalf are in their best interests are outlined. The use of physical intervention in special care dentistry in order to
provide dental care safely for both the patient and the dental team is also considered.

INFORMED CONSENT
Informed consent is required from all
patients or, in the case of children, par-
ents. Without it, dental treatment tech-
nically and legally becomes assault. The
model of informed consent comes from
medical practice and is based on free-
will, capacity and knowledge. Such
knowledge needs to be sufficient for the
person to come to a decision to refuse or
agree to the proposed treatment. Hence,
the patient, or parent/guardian, must
understand the potential risks and ben-
efits of the treatment and legally agree
to accept those risks in writing. Further-
more, the risks and possible side effects
must be explained in easy to understand
language, so that consent means that
the consenting person understands what
they are agreeing to and feels under no
pressure to give a particular response.

Giving consent to a procedure does
not necessarily waive the patient’s legal
rights. The healthcare professional still
has to follow through using the proper
standard of care as the patient can still
make a claim if the health provider func-
tions incompetently. Informed consent
can be complex to evaluate, because nei-
ther expressions of consent, nor expres-
sions of understanding of implications,
necessarily mean that full adult consent
was in fact given, or that full comprehen-
sion of relevant issues has been internally
digested.

Many times, consent is implied
within the usual subtleties of commu-
nication, rather than being explicitly
negotiated verbally or in writing. Conse-
quently, there is always a degree to which
informed consent must be assumed or
inferred, based upon observation, knowl-
edge, or legal reliance. In medical or for-
mal circumstances, explicit agreement by
means of signature, which may usually
be relied upon legally, is the norm. In the
dental setting, implied consent is assumed
if a patient sits in the dental chair and
voluntarily opens their mouth for dental
examination or treatment. It is prudent
to obtain written consent for irreversible
procedures, such as exodontia, and it is
a requirement to obtain it for procedures
being carried out with sedation or gen-
eral anaesthesia. For many other proce-
dures, implied and verbal consents are
normal practice.
Essentially, informed consent:
