Currently, an extensive variety of toothpastes are available on the market, containing basic components that are ubiquitous in all toothpastes, in addition to unique constituents that bestow characteristic traits, and it is crucial to acknowledge that certain components found in toothpastes are not recommended for ingestion due to their potentially negative impact on overall wellbeing, especially in children. This study aims to highlight the role of natural components as a substitute for toothpaste in achieving good oral hygiene and to focus on natural compounds that do not injure the body, especially considering the current trend towards the use of natural substances. Thus, the objective of this paper is to emphasize the advantages of using organic products. In Romania, due to the socio-economic conditions in rural areas, the use of these ingredients, which are available to everyone, could lead to an improvement in oral health. The study shows that a majority of 63% of the participants who used a toothpaste composed of natural constituents achieved an ISL bacterial plaque index equivalent of zero. This is noteworthy as the presence of the plaque index was detected in a mere minority of 13% of the subjects at the commencement of the study. To evaluate the effectiveness of the mentioned compounds in plaque removal, all participants in the study were instructed to use the same brushing technique known as the Bass method, which is recognized as one of the most effective techniques. The study concludes that mastery and application of the correct brushing technique, combined with toothpaste obtained from natural compounds, is successful in removing plaque.

Background/Objectives: Physical fitness is a key determinant of health in university students, a population at risk of sedentary behaviors and lifestyle-related health issues. The European Fitness Badge (EFB) provides a comprehensive assessment of fitness parameters and individualized feedback. This study aimed to evaluate the physical fitness of Romanian university students using the EFB to examine the effects of activity profile, sex, age, and academic major and to associate physical fitness with body composition indices, including Body Mass Index (BMI) and A Body Shape Index (ABSI). Methods: A cross-sectional study was conducted with 180 university students (43.33% male; age 18–53 years). Participants were categorized into two fitness profiles: Basic (TP1) and Advanced (TP2). Physical fitness was assessed through standardized EFB protocols measuring endurance, strength, flexibility, coordination, and overall fitness. Independent t-tests, one- and two-way ANOVA, and Pearson correlations were used to analyze differences and associations. Results: TP2 participants scored significantly higher in endurance, strength, coordination, and overall fitness, Males outperformed females in strength and coordination. Strength decreased with age, particularly in the oldest group. The sports students demonstrated superior fitness compared to peers in other majors. Two-way ANOVA revealed significant interactions between profile and sex for strength and overall fitness. BMI and ABSI were negatively correlated with physical fitness, in strength, coordination, and overall fitness. Conclusions: The EFB proved effective in differentiating physical fitness profiles. Demographic factors and body composition influenced fitness outcomes, underscoring the need for targeted, profile-based physical activity strategies specifically adapted to university curricula and extracurricular sport programs. However, the findings should be interpreted in light of the study’s geographic limitation, as the sample included only Romanian university students.

Fitness instructors play an essential role in fitness services, as they require both technical and interpersonal skills. A good image of a fitness instructor can be defined as having a pleasant appearance and good presentation in terms of hygiene and/or clothing used, which is appropriate for the context and characteristics of the participants. Their image significantly influences participants’ perceptions and satisfaction. The objective of this study was to conduct a comparative analysis between Romania and Portugal regarding the quality of services offered within group fitness classes, focusing on instructors. It involved 133 group fitness instructors and 210 participants from Romania and Portugal. An adaptation of the Szumilewicz questionnaire was used to assess the importance of the different attributes of the fitness instructor’s image. Statistical analyses included descriptive statistics, t-tests, and effect size to compare perceptions between countries and groups. Romanian instructors and participants generally attributed more importance to the fitness instructor’s image compared to their Portuguese counterparts. Significant differences were found in attributes like physical fitness, technical execution, and communication. Instructors tended to overestimate the importance of their image compared to participants. The fitness instructor’s image is crucial in determining participant satisfaction and the perceptions of service quality. The innovative aspect of this study lies in its intercultural comparison, which highlights how cultural context influences the perception of a fitness instructor’s attributes, such as physical fitness, technical execution, and communication. The practical application of these findings lies in the suggestion that fitness professionals should tailor their approach, balancing technical skills and interpersonal communication to align with the cultural expectations of their participants. This culturally sensitive approach is essential for enhancing participant satisfaction and improving the overall quality of fitness services.

Physical fitness is a fundamental indicator of health, leading to increased interest in fitness activ-ities under professional guidance. Fitness instructors play an essential role, requiring both tech-nical and interpersonal skills. Their image significantly influences participants perceptions and satisfaction. The objective of this study is to conduct a comparative analysis between Romania and Portugal regarding the quality of services offered within group fitness classes, focusing on instructors. It involved 133 group fitness instructors and 210 participants from Romania and Portugal. An adaptation of the Szumilewicz et al. (2008) questionnaire was used to assess the importance of the different attributes of fitness instructor image. Statistical analyses included de-scriptive statistics, t-tests, and effect size to compare perceptions between countries and groups. Romanian instructors and participants generally attributed higher importance to the fitness in-structor’s image compared to their Portuguese counterparts. Significant differences were found in attributes like physical fitness, technical execution and communication. Instructors tented to overestimate the importance of their image compared to participants. The fitness instructor image is crucial in determining participant satisfaction and perceptions of service quality. This study highlights the need for a balanced approach in instructor training, emphasizing both technical proficiency and interpersonal skills tailored to cultural contexts.
