ABSTRACT
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 attitudes 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 Universidad 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 influence of the variables: age group, sex, place of origin and type of university, considering a significance 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 insufficient 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 insufficient 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 insufficient 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 presenting insufficient 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.

OBJECTIVES: To assess tooth shade matching practices among Nigerian Dentists. MATERIALSAND METHODS: The data was collected by paper questionnaire mailed at random to dentists insome Nigerian Teaching Hospitals and General Hospitals. The questionnaires comprised of two aspectsthat inquired about their biographical data and basic methods of shade selection. About 95% of thequestionnaires were retrieved and analyzed. RESULTS: 160 (83, males; 77 females) dentists participatedin the study. 71% performed tooth shade matching often, with restorative dentists (100%) mostlyinvolved than other specialists. 67% agreed that shade matching should be done in consultation withothers. However, only 40.6% actually consults others during shade selection. Also, 85% of the dentistsresponded correctly that shade matching should be done under natural lights. However in their clinicalpractice, majority (97%) selected their teeth under dental lights. CONCLUSION: The study revealedthat majority of the dentists practicing in the Nigerian Teaching and State Dental Hospitals are involvedin shade matching practices. Majority of the dentists performed tooth matching procedure withoutconcurrence from others and under dental light source. However few dentists reported complaintsfrom their patients. Emphasizing color science in dental curriculum and teaching new shade matchingsystems could be essential for improved restorative outcomes.
OBJETIVOS: Determinar os procedimentos de determinação de cor entre dentistas nigerianos.MATERIAIS E MÉTODOS: Os dados foram coletados por meio de questionários em papel,enviados aleatoriamente a dentistas em alguns hospitais de ensino e hospitais gerais. Osquestionários compreenderam dois aspectos de questões sobre dados biográficos e métodos básicosde seleção de cores. Em torno de 95 % dos questionários foram recuperados e analisados.RESULTADOS: 160 dentistas (83 homens, 77 mulheres) participaram do estudo. 71% executamescolha de cores, sendo que 100% dos dentistas restauradores o fazem, em número bem maior doque as demais especialidades. 67% concordam que escolha da cor deve ser feita em conjunto comoutras pessoas. Entretanto, somente 46,6 % realmente consultam uma segunda opinião durantea seleção de cores. Também 85% dos dentistas responderam que a escolha da cor deve ser feitasob luz natural. Entretanto, em sua prática clínica a maioria seleciona a cor sob luz de refletores.CONCLUSÃO: O estudo revelou que a maioria dos dentistas atuantes nos centros pesquisadospraticam a seleção de cores dentárias. A maioria procede sem consultar segunda opinião e sobluzes de refletores. Entretanto, poucos dentistas relataram queixas de pacientes. A ênfase daciência da cor no currículo dental e ensino de novos sistemas de escolha de cores poderia seressencial para a melhora dos resultados restauradores.
