title: Clinical decision-making in restorative dentistry. Content-analysis of diagnostic thinking processes and concurrent concepts used in an educational environment.
abstract: BACKGROUND
  Dental practice is affected by variation in diagnosis and treatment planning between clinicians. The process underlying the decisions leading to management of dental caries is poorly understood.
  
  
  OBJECTIVE
  To explore diagnostic thinking and identify information used in the diagnosis, management and treatment of caries.
  
  
  METHODS
  15 senior dental students (mean age, 23.1 years; 66% female) in Mexico City were interviewed using a Simulated Patient Model (SPM).
  
  
  METHODS
  The SPM consultation session and its review, aimed at eliciting an introspective recall description of the Diagnostic Thinking Processes (DTP) and the pieces of information (concepts) employed, were transcribed and content-analyzed (CA). CA reproducibility coefficients were 0.53 to 0.64. The cognitive psychology Gale & Marsden (GM) model was used to structure DTP and concepts. Data were analyzed with chi-squared tests.
  
  
  RESULTS
  DTP utilization was similar to the original report in endocrinology and neurology cases. A wide variety of concepts were combined with DTP to describe the strategies and information preferentially resorted to while addressing four areas identified in the consultation.
  
  
  CONCLUSIONS
  Narrow arrays of concepts of restorative concern (mostly physical features present in/on teeth) were often investigated using DTP 1, 2 and 4 in combination with the use of dental explorers. The heuristics detected link features common to the GM model and to an indirect pattern-recognition model, whereby reliance on visual/tactile concepts facilitates the acquisition of a clinically meaningful image. Non-clinical factors believed to be at play in the application of strategies were not investigated but were controlled for in the SPM.
