The information you have gathered forms your ‘evidence base’ and is critical to making
the decision about undertaking each intervention being considered. It is worth
reinforcing that published literature is not the only ‘evidence’ that is a valid support for
making a decision. A search of the peer-reviewed oral health promotion literature can
be discouraging as many interventions have not met rigorous scientific methodologies
or measures of success. Furthermore, there is very little oral health promotion literature
published that is specific to New Zealand. As a result, you will probably find that you
need to consider a range of information, including information from quantitative and
qualitative research, key informant interviews, case studies, consultation with experts,
and the evidence and experience gained in non-oral health disciplines. It may be useful
to form an advisory team of people with a range of skills and knowledge to assess the
information
