Introduction - Anatomy

Anatomy (Greek anatomē, "dissection") is the study of the structure of organisms and their parts.

Introduction - Physiology

Physiology is the scientific study of the functions and mechanisms within a living system.
Focuses on how organisms, organ systems, organs, cells, and biomolecules carry out chemical and physical functions in a living system.

Introduction - Dental Anatomy

Dental Anatomy is the study of the development, morphology, function, and identity of teeth in human dentitions.
Includes how teeth relate in shape, form, structure, color, and function to other teeth in the same arch and the opposing arch.

Introduction - Oral/Dental Physiology

Oral/Dental Physiology is the science dealing with the function of oral structures.
Covers structure and function of the oral ecosystem.
Includes aspects like mastication (chewing), swallowing, and speech.

Introduction - Dental Arch

Dental Arch is the composite structure of natural teeth and alveolar bone.
Teeth are arranged in the form of a dental arch (arcade) or catenary curve.

Introduction - Dental Arches

Maxillary Arch
Mandibular Arch

Introduction - Midline

Midline is an imaginary vertical line dividing each arch and the body into approximately equal halves.
It is a two-dimensional plane, called mid-sagittal plane.

Classification of Dentitions

Dentition explains the number, type, and arrangement of teeth.
- Mixed
- Permanent
- Mammalian dentition
Human dentition is heterodont - comprised of different types of teeth for different functions in mastication.
Human dentition is diphyodont - two sets of teeth. Monophyodont - one set of teeth. Polyphyodont - more than two or continuous sets of teeth.

Classification of Dentitions - Types

Primary/Deciduous Dentition: first teeth to erupt into the oral cavity, typically erupt from 6 months to 2 years, then exfoliate (lost)
Primary Dentition Includes: 20 teeth
Mixed Dentition Period: Transitional phase when both deciduous and permanent teeth are present, typically from 6-12 years of age
Permanent Dentition: Period when only permanent teeth are present, begins around 12 years of age. Permanent Dentition Includes: 32 teeth

Classification of Dentition - Tooth Types

Incisors (2 per arch)
Canines (1 per arch)
Premolars (2 per arch)
Molars (3 per arch)

Succedaneous Teeth

Permanent teeth that replace deciduous teeth, including incisors, canines, and premolars
Molars are not succedaneous
Process of deciduous teeth shedding and replacement involves exfoliation and resorption.

Dentition Periods

Prenatal
Primary Dentition
Mixed Dentition
Permanent Dentition
