Learning Outcomes

  • Define oral/dental anatomy and physiology
  • Distinguish right and left sides of a patient, midline, anterior and posterior teeth
  • Explain classifications of dentitions
  • Interpret primary/deciduous and permanent dentitions
  • Compare primary, mixed, and permanent dentition periods
  • Distinguish succedaneous teeth

Introduction - Anatomy

  • Anatomy (Greek anatomÄ“, "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
