  1. () = Reference category
  2. (Techn/univ) = (Technical or university education completed)
  3. OR = odds ratio
  4. [95% CI] = 95% confidence interval
  5. $ = Thousands of Chilean pesos.
  6. Infrequent visits = Last visit to the dentist was more than a year ago.
  7. Never = Never has visited a dentist.
  8. Symptoms related visit = Last visit to the dentist was due to symptoms.
  9. Subjects who have never visited a dentist were excluded from the model concerning the frequency of dental visits and the model concerning symptoms related visits (Table 2). Subjects who could not be classified in either a symptomatic or an asymptomatic dental attendance pattern were also excluded from the last model.
  10. # = the categories '$500–999' and '≥$1,000' were collapsed into ≥$500.
  11. & = the categories 'no education'; 'incomplete primary school'; 'primary school completed', and 'incomplete high school' were collapsed into 'up to primary school completed'. The categories 'high school completed', 'technical incomplete', and 'university incomplete' were collapsed into 'high school completed'; the categories 'technical education completed' and 'university education completed' were collapsed into 'technical/university completed'.
