    Study Notes

    Dentistry

    • Dentistry is a branch of medicine focusing on the study, diagnosis, prevention, and treatment of oral cavity diseases and disorders.

    Dental Terminology

    • Dentists are the doctors who practice dentistry.
    • The supporting dental team includes dental assistants, dental technicians, and dental hygienists.

    Anatomy of Oral Cavity

    • Skull Bones: The maxilla forms the upper jaw and the mandible forms the lower jaw.
    • Alveolar Bone: Part of the mandibular and maxillary bone, it surrounds teeth and forms tooth sockets.
    • Tooth Anatomy: Features include the crown, gums, bone, and root. The following components are parts of a tooth:
      • Enamel: Outermost layer of the tooth.
      • Dentin: Layer beneath the enamel.
      • Pulp: Soft tissue within the tooth.
      • Cementum: Covers the root surface.
      • Periodontal ligament: Connects the tooth to the jawbone.
    • Oral Vestibule: Area between the lips/cheeks and teeth.
    • Oral Cavity Proper: Area medial to the teeth, including the hard palate, tongue, and floor of the mouth.
    • Frenum: Fold of tissue connecting the tongue/lips to the mouth.
    • Gingiva: The soft tissue surrounding and protecting the teeth and underlying bone.
    • Tongue:
      • Apex: Tip of the tongue.
      • Dorsal surface: Top surface of the tongue.
      • Lateral surface: Sides of the tongue.
      • Ventral surface: Undersurface of the tongue.
    • Floor of the Mouth: Supports the oral cavity beneath the tongue. Contains glands, nerves, and vessels.
    • Palate:
      • Hard palate: Bony front portion of the oral roof.
      • Soft palate: Muscular back portion of the oral roof. Includes the uvula.
    • Tooth function: Teeth mechanically break down food by cutting and crushing, preparing it for swallowing and digestion.
    • Primary Teeth: First set of teeth to emerge, also called deciduous teeth. Composed of 20 teeth, eventually exfoliated (lost) as permanent teeth erupt.
    • Permanent Teeth: Second set of teeth, erupting after deciduous teeth are lost. Composed of 32 teeth (16 in each jaw).

    Tooth Anatomy - Additional Details

    • Root Canal Treatment Steps:
      • Access cavity preparation
      • Pulp removal (infected pulp)
      • Root canal filling (e.g., gutta-percha).
      • Tooth restoration.

    Common Dental Terms

    • Nine Clinical Specialities:
      • Oral Medicine & Periodontology
      • Removable Prosthodontics
      • Conservative Dentistry
      • Endodontics
      • Fixed Prosthodontics
      • Orthodontics
      • Pediatric Dentistry
      • Oral & Maxillofacial Surgery
      • Oral & Maxillofacial Radiology

    Periodontology

    • Periodontium: Structures supporting the teeth: gingiva (gums), cementum, periodontal ligaments, and alveolar bone.
    • Periodontal Diseases:
      • Gingivitis: Inflammation of gingival tissue with no supporting tissue loss.
        • Plaques and calculus build up result in gingivitis
      • Periodontitis: Inflammation including the gingiva, periodontal ligament, and alveolar bone.
    • Plaque: Sticky bacteria constantly forming on teeth.
    • Calculus: Hard deposit of mineralized plaque on teeth.
    • Periodontal probing depth: Assessment of probe depths, plaque/calculus assessment, and soft tissues and implant conditions.
    • Scaling: Removal of calculus deposits from the tooth.

    Removable Prosthodontics

    • Edentulism: Loss of dentition (teeth) due to disease, trauma, or oral cancer.
    • Complete edentulism: Complete loss of all teeth (complete denture).
    • Partial edentulism: Partial loss of teeth (partial denture).
    • Complete denture: Complete replacement for lost teeth and soft tissue.
    • Partial denture: Partial replacement for lost teeth and soft tissue.
    • Impression trays: Devices for holding impression materials.

    Fixed Prosthodontics

    • This branch deals with replacing missing teeth or restoring badly damaged teeth using fixed prostheses.
      • Crown: A fixed restoration covering the entire tooth, restoring it to its original shape.
      • Abutment: Prepared tooth receiving the crown; in bridges, the teeth supporting the false teeth.
      • Bridge: A fixed prosthetic replacement for one or more missing teeth that connects to abutment teeth.
      • Pontic: The artificial tooth part in a bridge.

    Orthodontics

    • Orthodontics: Specialty focused on diagnosing, preventing, managing, and correcting mal-positioned teeth and jaws, and malocclusion.
    • Fixed appliances: Braces and wires.
    • Removable appliances: Removable retainers or aligners that are not fixed to the teeth.

    Pediatric Dentistry

    • Specialized care for children's teeth from infancy through teenage years.
    • Pulpotomy: Removal of the coronal portion of the pulp.
    • Pulpectomy: Complete removal of pulp from the crown and roots.
    • Stainless steel crown: Temporary metal crown used.

    Oral & Maxillofacial Surgery

    • Focus on the surgical aspects of the oral and facial regions.
      • Tooth extraction: Removal of a non-restorable tooth.
      • Surgical extraction: Removal of a non-restorable tooth by surgical intervention due to its situation.
      • Impacted tooth: Tooth unable to fully erupt due to its positioning.
      • Complications: Examples include pericoronitis.
      • Extraction Forceps: Tools used in extractions.
      • Dental Implants: Titanium replacement roots for missing teeth.
      • Facial Trauma: Damage to facial bones or soft tissues from injuries (motor vehicle accidents, assaults, etc.).

    Oral & Maxillofacial Radiology

    • Specialized in producing and interpreting radiographic images (X-rays) to diagnose disorders of the mouth, face, and jaws.
      • Periapical X-rays: Images showing the entire tooth structure including beyond the root attachment.
      • Panoramic X-rays: Two-dimensional view showing the whole maxilla and mandible.
      • Cone beam computed tomography (CBCT): More advanced method for 3-dimensional imaging.

    Human Dentition

    • Primary (deciduous) teeth: First set of teeth. 20 teeth in total (10 in each jaw), divided into anterior and posterior. Types include incisors, canines, and molars.
    • Permanent teeth: Second set of teeth. 32 teeth in total (16 in each jaw), divided into anterior and posterior. Types include incisors, canines, premolars, and molars.
    • Dental Formula: Method describing the arrangement and number of each type of tooth per side in both the primary and permanent dentitions.
    • Palmer notation: Method used for numbering teeth in the dental field.
    • Universal numbering system: System used based on anatomical positioning of the teeth (clockwise)
