Abstract Maternal mental health affects their children’s oral health. This study assessed the associations between maternal mental health and dental anxiety level, dental caries experience, oral hygiene, and gingival status among 6- to 12-year-old children in Nigeria. This was a cross-sectional study that recruited mother-child dyad participants through a household survey conducted in Ile-Ife, Nigeria. Data collected included the independent (maternal mental health risk, depressive symptoms, and child’s dental anxiety), and dependent (caries experience, oral hygiene status, and gingival health status) variables. Multivariate logistic regression analysis was conducted to determine the associations between dependent and independent variables after adjusting for confounders (mothers’ age, child’s age, sex, and socioeconomic status). Statistical significance was set at p < 0.05. Of the 1411 mothers recruited, 1248 (88.4%) had low mental health risk, and 896 (63.5%) had mild depressive symptoms. As for the children, 53 (3.8%) had caries, 745 (52.8%) had moderate to high dental anxiety, 953 (63.0%) had gingivitis and 36 (2.6%) had poor oral hygiene. The maternal mental health risk was not significantly associated with the child’s caries experience (AOR: 1.012; 95%CI: 0.860–1.190; p = 0.886), poor oral hygiene (AOR:1.037; 95%CI: 0.975–1.104; p=0.250), and moderate/severe gingivitis (AOR:0.887; 95%CI: 0.764–1.030; p = 0.115). Maternal depression status was not significantly associated with the child’s caries experience (AOR: 0.910; 95%CI: 0.802–1.033; p = 0.145), poor oral hygiene (AOR: 1.016; 95%CI: 0.976–1.057; p = 0.439), and moderate/severe gingivitis (AOR: 0.963; 95%CI: 0.861–1.077; p = 0.509). Maternal mental health risk and depression do not seem to be risk factors for schoolchildren’s oral health in Nigeria. Further studies are needed to understand these findings.

Abstract: The new theoretical ethical framework is a general frame or tool for ethical agents, developed to guide ethical reasoning during public health emergency preparedness and response. The TEF is based on the assumption that no existing ethical discourse in medical ethics alone is sufficient to address ethical issues of a PHE. The solutions suggested by existing approaches are limited in practicability and effectiveness, because they cannot address root problems and interplay among ethical problems. The reason for this insufficiency rests on the argument that ethical problems of PHEs have causal and reciprocal relationships, and any ethical decision-making framework should provide a wide enough perspective to consider relevant ethical norms and theories to suggest practical, implementable, coherent solutions compatible with the communal values and cultural norms. The TEF we suggest for PHEs embraces a holistic and integrated ethical perspective that enables us to comprehend that ethical problems that arise in various settings caused by PHE phenomena are in relationship with each other instead of addressing them as a standalone problem. The TEF provides decision-makers to achieve a coherent web of considered judgements compatible with ethical values and principles in various settings. This type of conceptualization offers a wide perspective to see causal and relational relationships among problems and produce outcomes that would not be possible by eclectic approaches.

Resumo: O novo referencial ético teórico (NT: TEF, sigla em inglês) é um referencial geral ou instrumento para agentes éticos, desenvolvido para guiar o raciocínio ético durante o preparo e resposta a emergências de saúde pública (NT: PHE, sigla em inglês). O TEF é baseado na suposição de que nenhum discurso ético existente em ética médica sozinho é suficiente para abordar aspectos éticos de uma PHE. As soluções sugeridas pelas abordagens existentes são limitadas em praticabilidade e efetividade, porque elas não podem abordar problemas fundamentais e inter-relacionar problemas éticos. A razão para essa insuficiência repousa no argumento de que problemas éticos de PHEs têm relações causais e recíprocas, e qualquer referencial para tomada de decisão ética deve propiciar uma perspectiva ampla o suficiente para considerar normas e teorias éticas relevantes para sugerir soluções práticas, implementáveis e coerentes, compatíveis com valores comunitários e normas culturais. A TEF que sugerimos para PHEs abarca uma perspectiva ética holística e integrada que nos permite compreender que os problemas éticos que surgem em diversos ambientes causados pelo fenômeno da PHE estão em relação entre si, ao invés de abordá-los como um problema isolado. O TFE propicia a tomadores de decisões alcançar uma rede de julgamentos considerados compatíveis com valores e princípios éticos em ambientes diversos. Esse tipo de conceitualização oferece uma perspectiva ampla para observar relações causais e relacionais entre problemas e produzir desfechos que não seriam possíveis por abordagens ecléticas.

Resumen: El nuevo Marco Ético Teórico (MET) es una estructura general o herramienta para eticistas, desarrollada para guiar el razonamiento ético durante la preparación y respuesta a emergencias de salud pública (ESP). Supone que no existe un discurso ético en la ética médica que por sí solo sea suficiente para abordar temas éticos de ESP. Las soluciones sugeridas de aproximaciones existentes son limitadas en la práctica y en la efectividad, debido a que no pueden abordar problemas de raíz sin considerar las interacciones entre los problemas éticos. Esta insuficiencia es porque los problemas éticos de ESP tiene relaciones causales y recíprocas, y cualquier estructura de toma de decisiones éticas debería proporcionar una perspectiva suficientemente amplia como para considerar normas éticas y teorías relevantes, y sugerir soluciones prácticas que sean coherentes y compatibles con valores comunes y normas culturales. El MET que sugerimos para ESP abarca una perspectiva ética integral e integrada, que posibilita la comprensión de que los problemas éticos que surgen en varías situaciones causadas por fenómenos ESP se hallan en relación entre ellos, en vez de abordarlos como un problema aislado. El MET proporciona a los que toman decisiones el lograr una red coherente de juicios compatibles con los valores y principios éticos en varias situaciones. Este tipo de conceptualización ofrece una amplia perspectiva para ver relaciones causales y relacionales entre problemas y producir resultados que no serían posibles mediante aproximaciones eclécticas.

Abstract Oral hygiene, which is measured by the status of plaque-free tooth surfaces, is essential for the promotion of oral health. This study aimed to determine the social predictors of good oral hygiene for children in a suburban population in Nigeria. This was a secondary analysis of data. The study participants were 8- to 16-year-old children who were residents in Ile-Ife, which is a suburban population in Nigeria. Information on the age, gender, socioeconomic status, family structure, number of siblings and birth rank of each study participant was retrieved from the an interviewer-administered questionnaire. Oral hygiene status was determined through a simplified-oral hygiene index (OHI-S) and categorized as good, fair and poor. The association between oral hygiene status and sociodemographic variables was determined. The predictors of good oral hygiene were determined using a binomial regression analysis. Data on 2,107 individuals were retrieved, of which 44.8% had good oral hygiene and 17.1% had poor oral hygiene. The odds of having good oral hygiene were reduced for children who were 13 to 16 years old (p = 0.02) or male (P=0.002) and children with low socioeconomic status (p ≤ 0.001). The odds of having good oral hygiene increased for children who were last-born compared with those who were first-born (p = 0.02). Age, gender, socioeconomic status and birth-rank were significant social predictive factors of oral hygiene status among the study population. Based on these findings, targeted interventions can be conducted to improve the oral hygiene status of children and adolescents with these social profiles.

Abstract This study assessed the difference in the number of visits made to a dental care clinic and the time spent providing specific dental treatment for children with and without molar incisor hypomineralization (MIH). Children aged 8 to 16 years who presented at the Pediatric Dental Unit of the Obafemi Awolowo University Teaching Hospital Complex, in Ile-Ife, Nigeria, were eligible for the study. A comprehensive medical and dental history was taken, and each child was clinically examined, diagnosed, and treated according to a drawn-up plan. The time taken to establish a diagnosis and to provide specific treatments (scaling and polishing, restoration, pulpectomy, extraction, and placement of stainless steel crowns) and the number of visits made to complete the treatment plan were recorded for each child. Differences in the number of visits, time expended to make a diagnosis and to treat children with and without MIH were analyzed. The average time for diagnosis (p = 0.001) and the average time for placing amalgam restorations (p = 0.008) were significantly longer in children with MIH than in those without it. Children with MIH made more visits to the clinic (p < 0.001).There was no significant difference in the average time for scaling and polishing (p = 0.08), glass ionomer cement restorations (p = 0.99), composite restorations (p = 0.26), pulpectomy (p = 0.42), tooth extraction (p = 0.06), and placement of a stainless steel crown (p = 0.83) in children with and without MIH. In conclusion, children with MIH required more time for oral health care. Placing amalgam restorations took significantly longer than placing tooth bonding restorative materials in children with MIH than in those without it.

Abstract Aim: To determine if the prevalence of enamel hypoplasia, molar-incisor hypomineralisation (MIH) and deciduous molar hypomineralisation (DMH) is associated with the socioeconomic status of the child and to determine the prevalence of enamel hypoplasia and MIH/DMH co-morbidity in the study population. Methods: Information was collected on the sex and socioeconomic status of the 1,169 study participants' resident in Ile-Ife, Nigeria, recruited through a household survey. The children were clinically examined to assess for the presence of enamel hypoplasia, MIH and DMH. Associations between sex, socioeconomic status and the prevalence of enamel hypoplasia, MIH and DMH were determined. The proportion of children with enamel hypoplasia and MIH/DMH co-morbidity was also determined. Results: Among the 1,169 study participants, 47(4.0%) had MIH, 15 (1.3%) had DMH and 161 (13.8%) had enamel hypoplasia. One (0.09%) study participant had MIH/DMH co-morbidity, 12 (1.0%) had DMH/enamel hypoplasia co-morbidity, and 9 (0.8%) had MIH/hypoplasia co-morbidity. There was no significant association between the socioeconomic status and presence of enamel hypoplasia (p=0.22), MIH (p=0.78) or DMH (p=1.00). Conclusions: The socioeconomic status cannot be used as a distinguishing factor for enamel hypoplasia, MIH and DMH. The possibility of co-existence of enamel hypoplasia and MIH/DMH makes it imperative to find ways to distinguish between the lesions.
