Functional Classification of Joints01:09

Functional Classification of Joints

4.1K
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.

Tooth Anatomy01:21

Tooth Anatomy

478
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...

Classification of Bones

5.5K
The bones of the human skeletal system are of varied shapes, sizes, and functions. They can be classified based on their shape and function into four major classes: long bones, short bones, flat bones, and irregular bones. Some classifications include a fifth type, the sesamoid bones, as a separate class, whereas others categorize them under short bones.
Long and Short Bones
The appendicular skeleton, particularly the upper and lower limbs, is primarily made of long and short bones. The...

Aggregates Classification01:29

Aggregates Classification

326
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...

Classification of Signals01:30

Classification of Signals

466
In signal processing, signals are classified based on various characteristics: continuous-time versus discrete-time, periodic versus aperiodic, analog versus digital, and causal versus noncausal. Each category highlights distinct properties crucial for understanding and manipulating signals.
A continuous-time signal holds a value at every instant in time, representing information seamlessly. In contrast, a discrete-time signal holds values only at specific moments, often denoted as x(n), where...

Classification of Illness01:17

Classification of Illness

7.5K
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...

Area of Science:

  • Artificial Intelligence in Dentistry
  • Medical Image Analysis
  • Machine Learning for Healthcare

Background:

  • Rising prevalence of dental health issues requires accurate and timely diagnosis.
  • Automated dental condition classification systems offer a potential solution to support clinical needs.

Purpose of the Study:

  • To evaluate deep learning methods and multimodal feature fusion for automated dental condition classification.
  • To enhance the precision and robustness of dental diagnostic tools.

Main Methods:

  • Utilized a dataset of 11,653 dental images across six conditions: caries, calculus, gingivitis, tooth discoloration, ulcers, and hypodontia.
  • Extracted features using five Convolutional Neural Network (CNN) models and fused them.
  • Developed classification models using Support Vector Machines (SVM) and Naive Bayes classifiers.

Main Results:

  • The SVM classifier with feature fusion achieved a Kappa index of 0.909 and accuracy of 0.925.
  • This performance significantly outperformed individual CNN models, such as EfficientNetB0 (Kappa: 0.814, accuracy: 0.847).

Conclusions:

  • Feature fusion combined with advanced machine learning algorithms enhances the precision and robustness of dental classification.
  • This approach serves as a valuable tool for dental professionals, improving diagnostic accuracy and patient outcomes.
