Objective: To establish the relationship between the perception of safety with occupational and socio demographic factors of workers belong to 11 private dental clinics in Bogotá. Materials and methods: cross-sectional study in a population of workers belong to private dental clinics in Bogotá (Colombia). The sample included 105 dentists and 107 auxiliaries belong to 11 private dental clinics in Bogotá that accomplish the selection criteria. Occupational and socio-demographic variables and those related to the occupational safety and health system were included. The Nordic Questionnaire on Safety at Work was applied. For the socio-demographic factors of the studied population, we used descriptive statistics, absolute and percentage frequency measures, quantitative variables were described with measures of central tendency and dispersion; For the association of the qualitative variables with the type of perception, Pearson`s Chi-square test or Fisher`s exact test was used for expected values less than 5. Results: The most perceived dimensions were those related to confidence in the efficacy of safety systems (D7 3. 35 ± 0. 43) and the Management safety justice (D3 3. 1 ± 0. 55). The dimensions that evaluate the Management safety empowerment (D2 2. 74 ± 0. 99) and the Workers’ safety priority (D5 2. 64 ± 0. 54) had the lowest perception. The perception of safety was good in general considering that the average of all the dimensions was superior to 2. 5; Significantly higher perception in men (3. 78 ± 0. 38), odontologists (3. 89 ± 0. 38) and people who had a partner (3. 83 ± 0. 4). People with additional work (4. 07 ± 0. 17), higher educational level (3. 89 ± 0. 31), higher working age (3. 92 ± 0. 51) and workers older than 30 years old (3. 89 ± 0. 35) showed a better perception of safety. In the multivariate analysis, the factors of labor and seniority found association in dimensions 2, 4 and 6 (p < 0. 001), whereas for numerical variables, dimensions 1, 3, 4 and 6 had a significant association between gender and position (P< 0. 001). Conclusions: The perception of security in the seven dimensions was related to gender, age, marital status, educational level, appointment, position and length of service. No significant differences were found per work shift or clinic.
