Background
Identifying patients with high levels of DA helps to define the most adequate oral healthcare strategy, especially for pediatric patients.
Aim
To investigate the association between ...parental reports of dental anxiety (DA) and molar incisor hypomineralization (MIH) in schoolchildren.
Design
A cross‐sectional study was conducted in a representative sample of 731 8‐year‐old schoolchildren from the city of Curitiba, Brazil, who were clinically examined (k ≥ 0.75) for the diagnosis of MIH and dental caries using the EAPD criteria and dmft/DMFT index, respectively. Parents/guardians reported children's DA using the Dental Anxiety Question (DAQ) and answered a self‐administered structured questionnaire addressing socioeconomic and demographic characteristics. Associations were evaluated using Poisson regression analysis with robust variance (P < 0.05).
Results
A significant association was found between DA and MIH (PR = 1.20; 95%CI: 1.01‐1.42; P = 0.038), but this association lost its significance when adjusted for the other characteristics (PR = 1.13; 95%CI: 0.93‐1.38; P = 0.215). Caries experience in primary teeth was associated with lower levels of DA (PR = 0.83; 95%CI: 0.71‐0.96; P = 0.0013). The most recent visit to the dentist due to pain increased the levels of DA (PR = 1.18; 95%CI: 1.07‐1.30; P = 0.001).
Conclusions
The presence of MIH in schoolchildren was not associated with parental reports of DA.

Introdução: a Hipomineralização Molar-Incisivo (HMI) é considerada uma condição clínica ainda sem etiologia definida, que acomete os primeiros molares permanentes e, frequentemente, os incisivos ...permanentes, causando grandes impactos desde o acometimento da estética até a perda dental. Objetivo: este estudo buscou avaliar o nível de conhecimento dos acadêmicos do curso de graduação em Odontologia sobre a HMI. Materiais e Métodos: a pesquisa foi realizada com os acadêmicos matriculados da primeira a décima fase do curso de Odontologia de um centro Universitário de Santa Catarina. Os dados foram obtidos através de um questionário semiestruturado e imagens de dentes com defeitos de formação em esmalte. Resultados: pode-se observar que os acadêmicos de períodos finais (27,1%) apresentaram maior confiança em realizar o diagnóstico de HMI quando comparados aos acadêmicos de períodos iniciais(14,5%) (p<0,041). A maioria dos participantes acertou a resposta quanto à prevalência da HMI (p<0,001). Em relação ao diagnóstico clínico da HMI, observou-se que 69% dos acadêmicos que tinham o conhecimento soube identificar através da imagem clínica. Entretanto, 77,6% dos acadêmicos que não tinham conhecimento sobre a HMI responderam incorretamente (p<0,001). Conclusão: há uma parcela significante de acadêmicos do curso de Odontologia que ainda não possui conhecimento suficiente sobre a HMI. Desta forma, a formação acadêmica deve melhorar a abordagem e suprir essa dificuldade.
Introduction: molar-Incisor Hypomineralization (MIH) is considered a clinicalcondition with no defined etiology yet, which affects the first permanent molarsand, frequently, the permanent incisors, causing major impacts ranging fromaesthetic impairment to tooth loss. Objective: this study evaluated the level ofknowledge of undergraduate Dentistry students about HMI. Materials andMethods: the research was carried out with students enrolled in the first to tenthperiod of the Dentistry course at a university center in Santa Catarina. Data wereobtained through a semi-structured questionnaire and images of clinical caseswere used for diagnosis. Results: it can be observed that students in final periods(27.1%) were more confident in carrying out the MIH diagnosis when compared tostudents in initial periods (14.5%) (p<0.041). Most participants answered correctlyregarding the prevalence of MIH (p<0.001). Furthermore, 69% of students who hadknowledge about MIH correctly diagnosed the image of teeth compromised byMIH. However, 77.6% of students who had no knowledge about HMI answeredincorrectly (p<0.001). Conclusion: there is a significant portion of Dentistry studentswho still do not have sufficient knowledge about HMI. Therefore, academic trainingmust improve the approach and overcome this difficulty.
