Functional Classification of Joints01:09

Functional Classification of Joints

6.2K
Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses  or amphiarthroses, whereas all synovial joints are classified as diarthroses.

Classification of Systems-II01:31

Classification of Systems-II

411
Continuous-time systems have continuous input and output signals, with time measured continuously. These systems are generally defined by differential or algebraic equations. For instance, in an RC circuit, the relationship between input and output voltage is expressed through a differential equation derived from Ohm's law and the capacitor relation,

Linearity is a system property characterized by a direct input-output relationship, combining homogeneity and additivity.
Homogeneity dictates that if an input x(t) is multiplied by a constant c, the output y(t) is multiplied by the same constant. Mathematically, this is expressed as:

Classification of Illness01:17

Classification of Illness

8.4K
The meaning of illness is individualized to each person who experiences an alteration in health. In contrast, disease is a medical term indicating a pathological change in the structure and function of the body or mind. It is a condition that has specific symptoms and boundaries.
An illness is a response to a disease in which the person's level of functioning is changed compared with a previous level. The general classification of illness includes acute and chronic.
Acute illness is severe...

Classification of Leukocytes01:30

Classification of Leukocytes

4.5K
Leukocytes are classified into two groups based on the presence or absence of cytoplasmic granules. Granular leukocytes, which contain granules, belong to the myeloid lineage and are divided into three subtypes: neutrophils, eosinophils, and basophils. These cells are roughly spherical and characterized by the granules in their cytoplasm.
Neutrophils are the most abundant type of granular leukocytes, comprising 50-70% of all leukocytes. They feature small, evenly distributed granules and a...

Aggregates Classification01:29

Aggregates Classification

730
Aggregate classification is generally based on its size, petrographic characteristics, weight, and source. Size classification ranges from coarse to fine aggregates, defined by the size of the particles. Coarse aggregates are particles that do not pass through ASTM sieve No. 4, and aggregates that pass through the sieve are fine aggregates.
Petrographic classification groups aggregates based on common mineralogical characteristics. Some of the common mineral groups found in aggregates are...

Area of Science:

  • Dentistry
  • Periodontology
  • Dental Diagnostics

Background:

  • Tooth mobility is frequently assessed using numerical scales (1, 2, 3) by dental professionals.
  • A lack of clear definitions for these numerical categories leads to ambiguity in clinical practice.

Purpose of the Study:

  • To conduct a comprehensive review and discussion of the primary clinical classifications of tooth mobility.
  • To address the inconsistencies and inaccuracies in current literature regarding tooth mobility assessment.

Main Methods:

  • Extensive electronic database searches were performed in MEDLINE, Scopus, and PubMed.
  • Manual searches of textbooks, gray literature, and bibliographies of relevant articles were also conducted.

Main Results:

  • The Miller index is the most frequently cited clinical index for tooth mobility.
  • Numerous other classifications and modifications of existing indexes exist.
  • The literature demonstrates significant inconsistency and inaccuracy in classifying tooth mobility, with interchangeable use of grades, classes, and scores without defined meanings.

Conclusions:

  • A comprehensive discussion of different tooth mobility classifications and definitions is provided.
  • Consistent and accurate use of mobility classifications is crucial for clinical clarity.
  • There is a clear need to standardize a single classification system for tooth mobility.
