Justice in dental ethics primarily addresses:

Justice in dental ethics centers on the fair treatment of all patients. This principle emphasizes the need for equitable access to dental care, where patients are treated without discrimination based on race, socioeconomic status, or personal circumstances. It aims to ensure that all individuals receive appropriate care and that their rights as patients are respected, aligning with the ethical commitment of healthcare providers to treat all patients justly and fairly.

In the context of this question, the other options do not embody the essence of justice in dental ethics. While cost-effective treatment solutions are important for sustainability in healthcare, they do not specifically address fairness in treatment. Providing preferential treatment to loyal patients contradicts the principle of justice, as it creates inequality among patients who may not have the same level of loyalty or resources. Lastly, maximizing practice profitability is primarily an economic concern rather than an ethical one and does not align with the fundamental goal of justice in healthcare, which is to ensure equitable treatment for all patients.
