Background The dentist should have a thorough knowledge of the science, protocols and procedures for dental
shade selection in order to mimic dental tissue with restorative materials, respecting the individual needs and atti‑
tudes of each patient and providing them with a pleasant and esthetically acceptable appearance. The present study
evaluated the knowledge and attitudes of dental interns from two Peruvian universities about dental shade selection
and its relationship with sociodemographic factors.
Methods The present cross-sectional and analytical study was carried out on Peruvian dental interns from the Uni‑
versidad Nacional Federico Villarreal and the Universidad Privada de San Juan Bautista during May to June 2022. Two
validated questionnaires on knowledge and attitudes about dental shade selection were used. A Poisson regression
model with robust variance using the adjusted prevalence ratio (APR) was used to assess the infuence of the vari‑
ables: age group, sex, place of origin and type of university, considering a signifcance level of p<0.05.
Results The results showed that 40.8% (95% CI: 34.0% - 47.6%) of the interns presented unfavorable attitudes
while 90.1% (95% CI: 86.0% - 94.2%) presented insufcient knowledge. It was also found that dental interns under 29
years of age were 32% less likely to have unfavorable attitudes (APR = 0.68, 95% CI 0.48 - 0.96) and 11% more likely
to have insufcient knowledge (APR = 1.11, 95% CI 1.01 - 1.24) about tooth shade selection compared to dental
interns aged 29 years and older. Finally, women were 55% more likely to have unfavorable attitudes about tooth
shade selection compared to men (APR = 1.55; 95% CI: 1.08 - 2.22).
Conclusion The majority of dental interns presented insufcient knowledge and less than half had unfavorable
attitudes about dental shade selection. In addition, being a student under 29 years of age was a risk factor for present‑
ing insufcient knowledge and at the same time constituted a protective factor for presenting unfavorable attitudes.
Likewise, being a female student was a risk factor for presenting unfavorable attitudes about dental shade selection.
