Geranium robertianum L. is used in traditional medicine to treat different systemic disorders and holds great therapeutic potential but remains understudied. To this aim, an ethanolic extract obtained from the aerial parts of G. robertianum L. (GR) was investigated in terms of phytochemical composition and biological activity. GR extract exhibited high levels of phenolic compounds and flavonoids. The antioxidant activity was determined by means of three different colorimetric assays (DPPH, ABTS, and FRAP), and the results obtained indicate that the ABTS assay showed the highest antioxidant capacity. Metal analysis was also performed. Fe was found to be the most abundant element in the analyzed extract, with a concentration of 363.65 ± 4.18 μg/g, followed by Zn, Mn, Ni, and Cr. Four potentially hazardous heavy metals, As, Co, Pb, and Cd, were found to be under the detection limit. The GR extract exhibited moderate antibacterial activity against both Gram-positive and Gram-negative bacteria, with inhibition zones generally comparable to those of levofloxacin. However, the extract was significantly less effective against the P. aeruginosa strain. On A253 human salivary gland carcinoma cells, GR extract elicited a dose-dependent antiproliferative effect, produced morphological changes, and increased ROS and both caspase-3/7 and caspase-9 levels.

Context: The increasing incidence of secondary caries and the failure of restorations have intensified research into dental restorative materials capable of actively interacting with the oral environment. In this context, antibacterial and bioregenerative nanomaterials have attracted growing scientific interest due to their potential to inhibit biofilm formation while simultaneously supporting mineral repair processes. Objective: This narrative review analyzes recent developments in nanostructured materials for restorative dentistry and oral health applications, with particular emphasis on antibacterial agents, bioactive systems, and emerging dual-function approaches that integrate multiple biological functions into restorative materials. Scope of the Review: The analyzed literature indicates that metallic nanoparticles, cationic monomers, and natural nanopolymers can reduce bacterial adhesion and metabolic activity under experimental conditions. In parallel, bioactive nanomaterials such as nanohydroxyapatite, bioactive glass, and calcium phosphate-based systems have demonstrated the ability to release remineralizing ions and to promote mineral deposition at the tooth–material interface. Dual-function hybrid materials aim to combine these antibacterial and bioregenerative effects within a single restorative system. Interpretative Perspective: Despite these advances, most available evidence derives from in vitro and preclinical studies, with significant heterogeneity across experimental models, evaluation methods, and outcome variables. This variability limits direct comparisons between studies and necessitates a cautious interpretation of claims regarding long-term antibacterial efficacy, functional tissue regeneration, and routine clinical applicability. Conclusions: Antibacterial and bioregenerative nanomaterials represent a relevant and continuously evolving research direction in restorative dentistry. Their successful clinical translation will depend on establishing standardized testing protocols, conducting comprehensive safety assessments, and generating clinically relevant evidence supporting long-term efficacy and biological compatibility. Their successful clinical translation will depend on establishing standardized testing protocols, conducting comprehensive safety assessments, and generating clinically relevant evidence supporting long-term efficacy and biological compatibility.

Introduction: Dietary habits adopted during young adulthood play a critical role in physical, emotional, and cognitive health. University students represent a particularly vulnerable group due to academic stress, lifestyle transitions, and increased autonomy, factors that may influence eating behaviors, body weight perception, and psychological well-being. This study aims to examine dietary habits among students and their associations with self-perceived body weight, lifestyle characteristics, and psychological factors within a biopsychosocial framework. Materials and Methods: A cross-sectional observational study was conducted using a structured, self-administered online questionnaire distributed to university students aged 18–30 years in Romania. The questionnaire assessed dietary habits, nutritional knowledge, lifestyle behaviors, and psychological variables, including perceived stress and body weight perception. Body mass index was calculated based on self-reported anthropometric data. Results: The findings indicated substantial variability in dietary behaviors, with a high prevalence of irregular meal patterns, frequent snacking, and engagement in weight-control practices. Irregular meal patterns were reported by approximately 62% of participants, while 47% had engaged in at least one weight-loss diet. Discrepancies between self-reported BMI and perceived body weight were observed in roughly 38% of cases, and 83% of respondents reported at least one psychological symptom (stress, anxiety, or low mood) related to eating behaviors. A positive correlation was observed between sleep duration and perceived rest quality (r = 0.364, p < 0.001). High frequencies of caffeinated beverage consumption were also observed. Additionally, 204 participants reported no alcohol consumption, while the variety of alcoholic beverages consumed was strongly correlated with alcohol intake frequency (r = 0.734, p < 0.001). Conclusions: Dietary habits among university students are closely interconnected with body weight perception, lifestyle behaviors, and psychological well-being. These findings emphasize the need for integrative health promotion strategies that address nutrition, emotional regulation, and lifestyle balance to support mental and cognitive health during young adulthood.

Background: The rapid evolution of dental adhesive systems presents both opportunities and challenges for clinical practice, particularly regarding the translation of emerging evidence into routine use. Aim: This study aimed to assess the knowledge, attitudes, and self-reported practices related to modern adhesive systems among Romanian dentists and to explore factors associated with their clinical decision-making. Materials and Methods: An observational cross-sectional study was conducted between November 2025 and February 2026 using a 115-item online questionnaire. A convenience sample of 372 Romanian dentists participated. Statistical analysis included descriptive statistics, chi-square and Kruskal–Wallis tests, and multivariate models (multiple linear regression, binary logistic regression, and multinomial logistic regression). Internal consistency of the knowledge scale was assessed using Cronbach’s alpha. Results: The knowledge scale demonstrated good reliability (Cronbach’s α = 0.873). Although 68.0% of respondents reported familiarity with universal adhesives, a discrepancy between awareness and reported clinical application was observed for several key concepts, including MMP inhibitors and hydrolytic stability. Notably, 14.8% of participants were unaware whether their preferred adhesive system contained 10-MDP. Continuing education frequency was the only independent predictor of higher knowledge scores (β = 1.63, p = 0.024), while greater clinical experience was inversely associated with rubber dam use (OR = 0.550, p = 0.024). Conclusions: The findings suggest a discrepancy between theoretical knowledge and the clinical implementation of modern adhesive concepts. Structured continuing education plays a critical role in improving knowledge and may help bridge this gap in clinical practice.

Universities play a strategic role in advancing the Sustainable Development Goals (SDGs) through community engagement, particularly within medical education. This study examines medical students’ involvement in volunteering activities and evaluates how such engagement contributes to SDG 3 (Good Health and Well-being) and SDG 4 (Quality Education). A cross-sectional survey was conducted among 499 students from the Victor Babeș University of Medicine and Pharmacy in Timișoara, using a structured questionnaire assessing perceived community impact, soft skills development, motivation for volunteering, sustainability orientation, and institutional support. Results indicate a high level of availability and prior participation in volunteering, reflecting strong internalization of public health and social responsibility values. While no significant differences were observed between volunteers and non-volunteers regarding perceived community impact (SDG 3), volunteer experience was significantly associated with higher levels of soft skills development and motivation (SDG 4). Strong positive correlations were identified between perceived community impact and motivational, educational, and sustainability related dimensions. The intensity of involvement was modestly associated with sustainability orientation and institutional support. Despite high motivation, students reported limited structured institutional frameworks for sustained engagement. The findings suggest that medical volunteering functions as a dual mechanism, strengthening professional competencies while reinforcing community health orientation. Institutionalizing structured outreach programs, particularly in underserved areas, could enhance long-term impact and align medical education more effectively with the 2030 Sustainable Development Agenda.

Background: The clinical translation of natural nanomaterials and smart delivery systems in regenerative dentistry relies heavily on practitioner acceptance; however, end-user perspectives remain under-investigated. Objective: This study evaluated dental practitioners’ self-reported knowledge, attitudes, and perceived barriers regarding these innovations. The questionnaire examined stated intention and self-reported willingness, not clinical behaviour. Methods: A cross-sectional survey using convenience sampling was conducted among 713 Romanian dentists. Statistical analysis included Chi-square tests and odds ratio estimation to identify factors associated with willingness to adopt nano-formulations. Results: Self-reported familiarity was moderate, with only 19.1% of respondents describing themselves as “very familiar” with nanodentistry; nevertheless, 77.3% believed natural nano-formulations could match synthetic efficacy. High costs (36.5%), lack of long-term evidence (35.9%), and staining concerns (46.0%) were identified as primary perceived barriers. Experience with digital technologies (CAD/CAM) was significantly associated with a positive attitude toward adoption (OR = 2.05, 95% CI: 1.41–2.98, p < 0.001). Conclusions: Respondents demonstrated a generally positive attitude toward integrating bioactive nanomaterials, though widespread adoption is currently limited by economic, educational, and evidentiary gaps. Future strategies should focus on establishing clear clinical protocols, providing robust long-term safety data, and improving the aesthetic stability of natural biomaterials.
