Study Notes
Oral Anatomy
- Dental anatomy is a field studying human tooth structures.
- It includes the development, appearance, and classification of teeth.
- This field is also considered a taxonomical science, as it categorizes and names teeth and their structures.
- This information is useful in dental treatment.
Nomenclature
- Teeth are named by their set, arch, class, type, and side.
- Teeth can be deciduous (primary) or permanent (secondary).
- Deciduous teeth, also known as "baby teeth", consist of 20 teeth.
- Permanent teeth range from 28 to 32 teeth, with the last four being wisdom teeth.
Deciduous Teeth
- These are primary ("baby") teeth.
- They are temporary teeth that precede permanent teeth.
Permanent Teeth
- These are secondary ("adult") teeth.
- There are typically 28 to 32 permanent teeth.
- Succedaneous teeth replace primary teeth, while non-succeded teeth like molars are not preceded by any primary teeth.
Midline
- An imaginary vertical line dividing both dental arches and the body into two equal halves, approximately.
Quadrants
- Dental arches are divided into four parts or quadrants, based on the midline
-
- Maxillary (upper) right.
-
- Maxillary (upper) left.
-
- Mandibular (lower) left.
-
- Mandibular (lower) right.
Occlusion
- The way mandibular teeth meet the maxillary teeth.
Mastication
- The process of chewing or biting food.
Classification of Dentitions
- Heterodont: Different types of teeth with different functions. Humans have this.
- Homodont: All teeth look the same, for example, lower vertebrates.
- Diphyodont: Has two sets of teeth (Deciduous and permanent sets). Humans have this.
- Monophyodont: One set of teeth.
- Polyphyodont: More than two sets of teeth are present (like some reptiles and fish).
Mixed Dentition
- The transitional phase involving both deciduous and permanent teeth.
Permanent Dentition
- The second set of teeth also known as the adult dentition.
- Typically there are 32 teeth in this set.
- It normally starts around 6-21 years of age.
Succedaneous Teeth
- Permanent teeth that replace deciduous teeth.
General Eruption Pattern
- Describes the sequence of tooth eruption (appearance).
- Deciduous teeth typically erupt earlier in the mouth.
- Permanent teeth generally replace deciduous teeth.
Numbering Systems
- FDI (Federation Dentaire Internationale)
- Universal system
- Palmer notation
Tooth Surfaces and Ridges
- Describing the names and locations of various surfaces and ridges (e.g., labial, buccal, lingual, palatal, incisal, proximal, mesial, distal, occlusal).
- These surface descriptions are important due to their crucial role in chewing.
- Also noting landmarks like pits and fossae.
Cusps
- pointed or rounded elevations on enamel.
Cingulum
- is the part of the anterior tooth on the lingual surface.
Pits and Fossae
- depressions in the crown of teeth.
Ridge Types
- including marginal ridges, triangular ridges, and oblique ridges.
