Change the 'Paradigm' by joini

Ab ovo

Before diving into the analysis of Masticationpedia, it is necessary to introduce some preliminary considerations. These concern, in particular, two fundamental dimensions - social, scientific, and clinical - that are characteristic of both the current era and the one immediately preceding it.

The phases of paradigm change according to Thomas Kuhn

In the course of the last century, there has been an exponential increase in technological and methodological "Innovations", especially in the field of dentistry. These advancements have significantly influenced decision-making strategies, opinions, schools of thought, and axioms, aiming explicitly at improving the quality of life, as highlighted in the "Science of Exposure in the 21st Century". However, this exponential growth implicitly hides conceptual ambiguities - or, in practical terms, "side effects" - which, although sometimes underestimated, have the power to challenge some scientific certainties, making them less rigid and more subject to probability. The sensitive aspects of the current social, scientific, and clinical reality, which may seem contrasting, will be revealed to be complementary by the end of this reading; this is the "Progress of science" according to Kuhn's interpretation and "Epistemology".

In analyzing the progress of science, Thomas Kuhn, in his most famous work, argues that science develops through distinct cycles, reflecting its operational dynamics. Kuhn advances the idea that science is structured around paradigms and establishes a clear demarcation between science and pseudoscience, based on the presence of a shared paradigm. For him, the evolution of scientific progress is seen as a continuous curve, yet interrupted by discontinuities represented by paradigm shifts.

Taking on the role of a skilled problem solver, the scientist is engaged in resolving these anomalies. These moments of discontinuity, or scientific revolutions, occur when the existing paradigm can no longer adequately interpret new anomalies, thereby pushing the scientific community towards the exploration and eventual adoption of new paradigms that better align with emerging observations.

Kuhn's phases in Dentistry

Thomas Kuhn identifies in the evolution of a scientific paradigm five distinct phases, a process that holds crucial importance for Masticationpedia. To stay in line with the project's objectives, we will focus on the description of the three most significant phases, as outlined in the book's index.

The phases of paradigm change according to Thomas Kuhn

Thomas Kuhn in his most famous work states that science cyclically passes through some phases indicative of its operation. According to Kuhn, science is paradigmatic, and the demarcation between science and pseudoscience can be traced back to the existence of a paradigm. The evolution of scientific progress is assimilated to a continuous curve which undergoes discontinuity in paradigm changes.

Kuhn's phases in Dentistry

Kuhn, on the other hand, divides the evolution of a paradigm into five phases; this is a fundamental process for Masticationpedia, but to stay tuned with the project we will limit ourselves to describing the three most significant phases shared in the project and indicated in the index of the book:

	Phase 2, or the Normal Science For instance, in the second phase of Kuhn's paradigms, called "Normal Science," scientists are considered problem solvers engaged in strengthening the correspondence between the paradigm and natural reality. This phase is based on a set of fundamental principles established by the paradigm itself, which are not subject to dispute but are instead used to define the guidelines for future research projects. During this phase, the development of the necessary measurement tools to conduct experiments takes place, and the majority of the scientific literature is produced. The results obtained in this phase contribute significantly to the advancement of scientific knowledge. In normal science, both successes and failures occur; the latter are identified by Kuhn as "anomalies," i.e., events that contradict the prevailing paradigm.
	Phase 4, or the Crisis of the Paradigm In response to the crisis, there will be the formation of several new paradigms during this period. These emerging paradigms, therefore, will not originate from the successes of the previous theory, but rather from the rejection of the established models of the dominant paradigm. Continuing along this line, Masticationpedia will dedicate attention to the crisis of the masticatory rehabilitative paradigm, through the review of theories, theorems, axioms, currents of thought, and diagnostic research criteria. Subsequently, the focus will shift to the fifth phase.
	Phase 5, or the Scientific Revolution Phase 5 is characterized by the scientific revolution. During the period of extraordinary scientific activities, a debate will develop within the scientific community on which new paradigm to adopt. However, the prevailing paradigm will not necessarily be the "truest" or most efficient one, but rather the one that manages to arouse the interest of a sufficient number of scientists and earn the trust of the community. According to Kuhn, competing paradigms have nothing in common, not even the foundations, making them "incommensurable." The choice of paradigm, as mentioned, occurs on socio-psychological or biological bases, with younger scientists replacing the older ones. This battle between paradigms will resolve the crisis, the new paradigm will be named, and science will return to Phase 1. Following the same principle of Phase 4, Masticationpedia will introduce, in the chapter named "Extraordinary Sciences," a new paradigmatic model in the field of Masticatory System rehabilitation, examining its principles, motivations, scientific clinical experiences, and particularly, a radical change in the field of medical diagnostics. This change is fundamentally based on "System Inference," rather than symptom-based inference, assigning primary importance to the objectivity of data.

It's almost taken for granted that Kuhn's scientific philosophy gives priority to discipline, since an anomaly within the genetic paradigm will be more easily recognized by a geneticist rather than a neurophysiologist. This concept, however, seems to contradict the epistemological evolution of Science, thereby making a detailed analysis of this apparent discrepancy appropriate.
