Introduction: early childhood caries is a non-communicable disease of high prevalence worldwide, in Cuba and on the Isle of Youth. Prevention and control approaches encompass changing personal behaviors, working with families and educators, and developing health policies, creating enabling environments, promoting health, and directing health services toward universal health coverage.
Objective: determine the effectiveness of the “Healthy Smile” program for preschool children.
Methods: a quasi-experimental before-after research was carried out where the sample was 95 preschool children from the La Demajagua-Atanagildo Cajigal towns in the period 2021-2023.
Results: before the educational intervention, the level of regular and poor knowledge prevailed in 76,8% and 16,8% respectively of the infants with a standard deviation of ±2,5; The level of knowledge increased after implementing the educational program, obtaining a good level of knowledge with 81,1% (77) with a tendency towards a regular level of knowledge 18,9% (18); standard deviation of ±1,4. The Student T test gave a value of tcalculated = 13,803, gl = 94 and p value = 0.000; therefore, there was evidence to reject the null hypothesis and accept the investigative hypothesis.
Conclusions: the implementation of the “Healthy Smile” program, involving families and educators, turned out to be effective since it modified ways and styles of life, also increasing the level of knowledge about oral health of infants.

Introduction: Migratory flows towards countries that have more labor supply are not recent. In this sense, the arrival of immigrants in host countries, in many cases, makes this population more susceptible to health risk situations because of work activities, lack of integration with the local population and the immigration process itself. Methods: The study used a bibliographic review of the literature as a method. In this context, integration policies and the recognition of educational training in the country of origin can contribute to improving the living conditions of this population in Brazil. Results: In this context, this study aims to provide a summary of the challenges faced by immigrants in search of improved living conditions. Furthermore, this study contributes to identifying the main challenges facing immigrants recently arrived in Brazil and the difficult process of integration into local society. It is observed that the authors highlight in common that, worldwide, in the different receiving countries, regardless of the social, political, and economic context in which the immigrants find themselves, there is some destructive process that conditions the health-disease process of this population, resulting from the various factors mentioned above. Conclusion: Yet the positive contribution of migration to development is increasingly recognized, and these targeted policies will maximize their benefits in both countries of origin and destination.

The Intercultural Health Nursing Role explores the role of nurses in culturally diverse environments and the challenges they experience; among them the language, customs, traditions and the perspective of managing health and illness, using Madeleine Leininger's Theory as a theoretical basis to develop a work plan according to the patient's worldview without leaving aside their own ideologies rather integrate them into it, without influencing their treatment, in order to provide culturally competent care. This research uses a bibliographic documentary selection methodology that allows the information to be analyzed and evaluated. A search was carried out for scientific articles published between 2020 and 2024 in databases such as ScieLo, Dialnet, Pubmed and search engines such as Google Academic using Boolean operators to optimize relevant information in relation to the topic raised above. A nursing professional must be able to interact with people of different ideologies, which is why it is necessary to have correct communication accompanied by cultural attributes that help a nurse develop the ideal ability to interact with people from different cultural contexts, without discriminating or emitting prejudices that violate the patient's autonomy. This research aims to analyze the role of nursing in intercultural health where it highlights the importance of cultural competencies in nursing professionals in these environments and highlights the value of the application of Madeleine Leininger's Theory in academics and professional practice.

This paper delves into how nurses perceive illness and death and how it impacts their daily practice. Nurses' perceptions are shaped by their educational background, professional experience, personal beliefs, and cultural context. They receive training in disease management and palliative care, providing them with the knowledge to approach these situations professionally. However, personal experiences, beliefs, and emotions also influence their response. The evolution of medical science has led to the medicalization of death, with nurses often caring for dying patients in hospital settings. The emotional burden on nurses necessitates emotional self-awareness and support networks to manage stress and trauma effectively. Cultural influences play a significant role in how nurses perceive illness and death. Some cultures avoid open discussions about death, creating communication barriers. Nurses must develop culturally sensitive communication skills to provide respectful care. Various medical traditions, such as Western medicine, Traditional Chinese Medicine, and Indigenous medicine, offer different perspectives on illness and death. Cultural differences extend to funeral practices and beliefs about the afterlife. Anonymous interviews with nurses highlighted their diverse responses to death and the emotional toll it can take. Support programs and psychological assistance should be available to help nurses cope with these challenges. In conclusion, nurses' perceptions of illness and death are multifaceted, influenced by education, experience, personal beliefs, and culture. Emotional management and institutional support are crucial for effective patient care. Creating an environment that encourages open communication and respect for these issues is essential. Nurses must engage in ongoing self-reflection to provide compassionate care and address the complex emotional aspects of their profession.
