    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

    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
