Study Notes
Basic Dental Terminology
- Dental terminology is for 1st-year dental students.
- The skull is made up of cranium and facial bones.
Anatomy of Skull
- The cranium encloses the brain.
- Eight bones make up the cranium:
- Temporal bones (fan-shaped, above each ear).
- Parietal bones (roof & side walls of the brain).
- Frontal bone (forehead).
- Occipital bone (back of skull, contains foramen magnum).
- Ethmoid bone (spongy, between orbits).
- Sphenoid bone (bat-shaped, base of skull).
Facial Bones
- Fourteen facial bones, all paired except vomer and mandible.
- Zygomatic bones (malar bones): cheekbones.
- Maxilla: upper jaw.
- Palatine bone: part of the hard palate.
- Nasal bone: forms the nose's bridge/arch.
- Lacrimal bones: inner side of nose/eye socket.
- Inferior nasal conchae: lower part of nasal cavity.
- Mandible: lower jaw.
- Vomer: lower part of nasal septum.
Anatomy of Mandible
- The mandible is the largest and strongest face bone.
- It has two parts:
- Body: horizontal (alveolar part and base).
- Ramus: vertical (coronoid and condylar processes).
- Landmarks: angle, mylohyoid ridge, oblique ridge, retromolar area, symphysis.
- The mandible articulates with the temporal bone (TMJ).
Muscles of Mastication
- Mastication (chewing) is controlled by paired muscles.
- Key muscles: temporal, masseter, medial pterygoid, lateral pterygoid.
- Other muscles: orbicularis oris, buccinator, mentalis.
The Tongue
- The tongue is a strong muscular organ in the oral cavity.
- It plays a role in chewing, talking, swallowing, and tasting.
- Papillae (taste buds) on the tongue surface, including circumvallate, filiform, fungiform, and foliate.
Muscles of Tongue
- The tongue muscles are intrinsic (shape) and extrinsic (position).
- Intrinsic muscles: superior longitudinal, inferior longitudinal, transverse, vertical muscles.
- Extrinsic muscles: genioglossus, hyoglossus, styloglossus, palatoglossus.
Palate Structure
- The palate forms the roof of the mouth.
- Two major parts: hard and soft.
- Hard palate features rugae (folds), incisive papilla, and a palatine raphe.
- Soft palate: flexible, closes off the nasal passage during swallowing.
Tooth Origin & Formation/Specialized Cells
- Types of teeth: deciduous (primary), permanent (secondary).
- Specialized cells: Odontoclasts, Cementoclasts, Osteoclasts.
- Mixed dentition (both primary and permanent teeth present at the same time).
- Tooth abnormalities: amelogenesis imperfecta, anodontia, dens in dente.
Tooth Eruption
- Tooth eruption happens in a predictable pattern.
- Specific teeth erupt at different times.
Tooth Landmarks
- Cingulum, ridges, triangular ridge, oblique ridge, fissure, and fossa.
- Understanding of pits and sulci is essential.
- Mamelon on newly erupted anterior teeth.
Tissue Structure of the Teeth
- Enamel, dentin, pulp.
- Pulp horns, pulpitis, pulp stone (denticle), granuloma, cementum
- Tissues covering tooth root structures: primary vs. secondary cementum.
Tissue Composition of the Periodontium
- Periodontal Tissues: periodontal membrane/ligament, alveolar bone, gingiva.
- Types of periodontal fibers: alveolar crest, horizontal, oblique, apical.
- Alveolar bone: supporting bone tissue.
- Gingiva (gum): attached, keratinized, marginal, papillary gingiva.
Odontology/Morphology
- Odontology: the study of teeth.
- Morphology: the study of tooth form and shape.
- Tooth types: incisors, canines, premolars, molars
- Tooth anatomy includes crown, root, apex, contact areas, and others.
Dental Professionals
- Different dental professions with varying roles.
- Dentists (DDS, DMD), Prosthodontists, Periodontists, Orthodontists, Endodontists, Oral and Maxillofacial Surgeons, Public Health Dentists, Dental Hygienists.
Orthodontic Practice and Malocclusion Classifications
- Orthodontia: the branch of dentistry that focuses on the prevention and correction of abnormally positioned or misaligned teeth.
- Malocclusion classifications (e.g., Class I, II, III).
- Individual tooth position classifications (e.g., mesioversion, distoversion).
- Causes of malocclusion (e.g., trauma, habits, and poor oral conditions).
Types and Methods of Orthodontic Treatment
- Preventive orthodontics (e.g., caries and space maintainers).
- Interceptive orthodontics (correct growth patterns).
- Corrective orthodontics (forces, appliances).
Diagnosis and Treatment Planning for Malocclusion
- Diagnosis steps (e.g., medical history, clinical examination).
