Hover over the labels above to understand Open Access, Member, and Affiliate.

Open Access Open Access

Free access to Masticationpedia’s introductory content, designed to help you orient yourself within the project and understand its clinical and conceptual framework.

It allows you to:

• read the extended abstracts
• understand the overall scientific direction
• explore language, models, and the epistemological framework

It does not include access to the full Book Index chapters nor editorial participation.

Affiliate Affiliation

Affiliation implies a recurring monthly support for the Masticationpedia project.

This contribution:

• is not a payment for a service
• does not guarantee authorship or automatic recognition
• does not represent commercial access to content

It is a form of ongoing responsibility toward the construction of the Ψ Index diagnostic model.

Monthly support distinguishes an Affiliate from a Member:

• a Member has reading access
• an Affiliate supports, participates, and contributes

Substantial scientific contributions may be acknowledged according to editorial criteria, not based on financial support.

❤️ Support the project (monthly)

The amount is freely chosen at the time of donation and is managed through CAF.

Affiliation also grants access to the Masticationpedia Network as a scientific and methodological participant.

Member Member

       The Book Index as a working map

Masticationpedia’s Book Index is not the table of contents of a finished book nor the final structure of a manual. It is a continuously evolving editorial and scientific working map.

The sections and chapters listed here do not represent a didactic pathway, but the points where clinical practice reveals fractures, anomalies, and paradigm limits that must be addressed without simplification.

“The Ψ Index is a clinical criterion, but it is born within a paradigm crisis: it does not only measure data, it reorganizes their interpretation.”

• Some chapters are complete, others partial; others are present as conceptual nodes.
• The order of the index is not final: it may change, be reorganized, or expanded.
• The Book Index does not contain final answers: it contains the conditions of their necessity.

       Sections and chapters evolve together with the project’s clinical and methodological work.

Ψ Index

When Normal Science fails: a clinical anomaly that opens the problem

PART I – LIMITS OF DESCRIPTION

Diagnosis as classification (RDC): describing is not inferring

Levels of clinical observation: a change in the scale of information

PART II – LIMITS OF CLASSICAL MEASUREMENT

Crisis of the absolute value: instability of the clinical number

Non-commutative variables in clinical practice: the order of information matters

PART III – FROM DATA TO STATE

System symmetry and stability : relation as information

System states : possible clinical configurations

PART IV – BEYOND THE NUMBER

The clinical state is not a number: the limit of the scalar

Clinical phase and encrypted signal : non-evident information

Artificial intelligence as a phase operator: NCN and semantic analysis

PART V – LIMITS OF CLASSICAL PROBABILITY

The limit of classical Bayes: probability without state

Quantum-like statistics: informational interference

PART VI – THE NEW CRITERION

From criterion to state index : inferring instead of classifying

Ψ Index: magnitude and phase of the clinical state
