Variation in decision-making – Phases of
decision-making
The clinical decision-making process in dentistry can be
divided into three separate phases
Differences in dentists’ decision making that results in
variation can arise within any of these three phases
n 1.  diagnosis, or more usually the detection phase,
where a disease is identified
n 2.  the decision about intervention, given that a
disease or condition is identified
Usually a yes/no decision, although dentists
routinely indicate uncertainty by noting in the
patient record that  a condition by “watched”
n 3.  selection of the treatment from among
alternatives, if a decision to intervene is made
