The patient satisfaction questionnaires in literature are according to the community pharmacies services in the authors’ countries and not all have psychometric reports to support the results. We designed a questionnaire specific to the services of community pharmacies in Romania to evaluate the level of patient satisfaction. We carried out a cross-sectional study on voluntary patients. The questionnaire consisted of 22 items, grouped into three domains corresponding to patient satisfaction with pharmacies, pharmaceutical staff and medication availability, and four subdomains related to pharmaceutical staff skills. The 5-point Likert scale was used. Statistical analysis was done in SPSS 27.0. The Cronbach’s Alpha was 0.861. The Inter-rater Agreement was 72.0%, the Item Content Validity was 97.6% and the completeness index was 100%. The factor analysis indicated 6 factors (Eigen values >1.0). The 809 patients had a median of overall satisfaction score of 3.77; the median was 4.0 regarding satisfaction score with pharmaceutical staff skills. Respondents characteristics varied the patient’s satisfaction level (p ≤ 0.05). The reliability and validity of the questionnaire have been demonstrated. Overall patient satisfaction with community pharmacy services had a moderate level, but the attitude and confidence in the pharmacist had a high level of satisfaction.

Background: This study examined how the concentration of calcium (Ca) influences the microstructure, mechanical characteristics, and tribological attributes of Mg–Ca–Zn–RE–Zr alloys for orthopedic medicine. Materials and methods: Experimental alloys with 0.1 and 0.5 wt% Ca were prepared in a controlled atmosphere induction furnace. The microstructure of the alloys was investigated by scanning electron microscopy, the chemical composition by X-ray fluorescence and energy-dispersive spectroscopy, the mechanical properties by indentation and scratching, and the corrosion resistance by linear and cyclic potentiometry. Results: The alloy with 0.1% Ca exhibited greater fluctuations in the coefficient of friction, while the sample with 0.5% Ca showed a higher susceptibility to cracking. Regarding corrosion resistance, both samples exhibited a generalized corrosion trend with similar corrosion currents. At lower Ca concentrations (0.1%), the refined microstructure of the alloys provided an elastic modulus closer to that of human bone, minimizing the risk of excessive local stress and promoting uniform load distribution at the bone-implant interface. Conclusion: The 0.5% Ca alloy offered superior tribological stability and better shock absorption, making it suitable for applications requiring long-term stability. The study highlighted the potential of both compositions based on the specific requirements of biodegradable orthopedic implants.

Background and Objectives: Magnesium (Mg)-based materials, such as the WE43 alloy, show potential in biomedical applications owing to their advantageous mechanical properties and biodegradability; however, their quick corrosion rate and hydrogen release restrict their general clinical utilization. This study aimed to develop a novel Mg-Zn-Ca alloy system based on WE43 alloy, evaluating the influence of Zn and Ca additions on microstructure, mechanical properties, cytocompatibility, and electrochemical behavior for potential use in biodegradable orthopedic applications. Materials and Methods: The WE43-Zn-Ca alloy system was developed by alloying standard WE43 (Mg–Y–Zr–RE) with 1.5% Zn and Ca concentrations of 0.2% (WE43_0.2Ca alloy) and 0.3% (WE43_0.3Ca alloy). Microstructural analysis was performed utilizing scanning electron microscopy (SEM) in conjunction with energy-dispersive X-ray spectroscopy (EDS), while the chemical composition was validated through optical emission spectroscopy and X-ray diffraction (XRD). Mechanical properties were assessed through tribological tests. Electrochemical corrosion behavior was evaluated using potentiodynamic polarization in a 3.5% NaCl solution. Cytocompatibility was assessed in vitro on MG63 cells using cell viability assays (MTT). Results: Alloys WE43_0.2Ca and WE43_0.3Ca exhibited refined, homogeneous microstructures with grain sizes between 70 and 100 µm, without significant structural defects. Mechanical testing indicated reduced stiffness and an elastic modulus similar to human bone (19.2–20.3 GPa), lowering the risk of stress shielding. Cytocompatibility tests confirmed non-cytotoxic behavior for alloys WE43_0.2Ca and WE43_0.3Ca, with increased cell viability and unaffected cellular morphology. Conclusions: The study validates the potential of Mg-Zn-Ca alloys (especially WE43_0.3Ca) as biodegradable biomaterials for orthopedic implants due to their favorable combination of mechanical properties, corrosion resistance, and cytocompatibility. The optimization of these alloys contributed to obtaining an improved microstructure with a reduced degradation rate and a non-cytotoxic in vitro outcome, which supports efficient bone tissue regeneration and its integration into the body for complex biomedical applications.

The presentation of complex treatment plans in dentistry requires a multidimensional approach. This involves not only advanced clinical skills, but also a solid ethical framework, clear, structured and ethically grounded communication between the doctor and the patient. In a context where therapeutic decisions involve extended duration, considerable costs and a high degree of interdisciplinary involvement, it is essential that the interaction with the patient respects deontological principles and supports his autonomy. This article analyzes the essential ethical and communicative aspects in the formulation, presentation and support of such therapeutic plans, with a focus on the doctor's responsibility in ensuring authentic informed consent and a therapeutic relationship based on trust, transparency, respect and empathy.

In the context of increasing competition and rising professional and economic demands within the dental field, the control function emerges as a key pillar for achieving efficient and predictable management. This paper analyses the key control elements applicable within a dental practice, with a particular focus on financial components, the quality of clinical procedures and treatments, and human resources. Relevant key performance indicators (KPIs) are highlighted to facilitate the objective evaluation of practice activities. Furthermore, the paper describes strategies and procedures necessary for the implementation of a functional control system. The aim is to provide a solid theoretical foundation and a practical framework for medical managers or dental practitioners seeking to optimize operations and ensure the sustainable enhancement of practice performance.
