Dental Anatomy Flashcards

A comprehensive set of flashcards covering key concepts related to primary dentition and dental anatomy.

Primary Teeth

Also known as deciduous teeth, baby teeth, or milk teeth, there are 20 primary teeth that erupt from 6 months to 3 years of age.

Primate Spacing

The spacing between anterior primary teeth that allows for the growth of larger permanent teeth.

Eruption Sequence

The chronological order in which primary and permanent teeth emerge.

Deciduous Dentition

The primary set of teeth that includes 20 teeth, which are replaced by permanent teeth.

Dentition

The general arrangement of teeth in the mouth, which includes primary, secondary, and mixed dentition.

Mixed Dentition

A stage where both primary and permanent teeth are present, typically occurring between ages 6 to 12.

Dental Age

The developmental stage of teeth that can be identified by examining a child's dental structure.

Ugly Duckling Stage

A phase during the mixed dentition period characterized by crowding and gaps as permanent teeth erupt.

Deciduous Crowns

The crowns of primary teeth, which are smaller and whiter than their permanent successors.

Permanent Teeth

The secondary set of teeth that replace primary teeth and include 32 teeth.

Root Completion

The process that begins after crown formation when the root of the tooth develops fully.

Crown Length

The measurement from the occlusal surface to the cemento-enamel junction of a tooth.

Mesiodistal Diameter

The measurement across the tooth from the mesial (toward the midline) to the distal (away from the midline) sides.

Pulp Chamber

The inner cavity of a tooth that contains the pulp tissue, which is larger in primary teeth compared to permanent teeth.

Enamel

The hard, outer layer of a tooth, which is thinner in primary teeth.

Dentin

The tissue underneath the enamel that makes up the bulk of the tooth structure.

Malocclusion

Misalignment of teeth and bite, which can occur during the mixed dentition stage.

Cervical Ridge

The pronounced ridge located at the cervix of the tooth, more prominent in primary molars.

Flared Incisors

A condition where upper front teeth appear angled outward during the eruption of permanent teeth.

Occlusal Surface

The biting surface of a tooth, which is narrower in primary molars compared to permanent molars.

Cemento-enamel Junction (CEJ)

The junction where the enamel of the crown meets the cementum of the root.

Deciduous Molars

Primary molars that serve as placeholders for the permanent premolars.

Enamel Rods

The structural units of enamel that in primary teeth slope occlusally at the cervical margin.

Cementum

The thin layer of bony tissue that covers the root of a tooth.

Flare

The outward spreading of the roots of primary molars, allowing space for developing permanent teeth.

Diastema

A gap or space between two teeth, often seen during the Ugly Duckling Stage.

Primary Canines

The first set of canine teeth that erupt, typically around age 16-22 months.

First Primary Molar

The primary molar that erupts typically around 14-18 months.

Second Primary Molar

The second primary molar that usually erupts around age 25-33 months.

Primary Central Incisor

The front primary tooth that typically erupts by 6-10 months.

Primary Lateral Incisor

The tooth that erupts next to the central incisors, typically around 9-13 months.

Eruption Timeline

The average age ranges for the eruption of primary teeth.

Dentin Thickness

Primary teeth have comparatively thicker dentin over the pulpal wall than permanent teeth.

Clinical Considerations

Factors related to primary teeth that are important for dental health education.

Dental Caries

Tooth decay that can progress rapidly in primary teeth due to thinner enamel.

Mandibular Teeth

The set of teeth located in the lower jaw.

Maxillary Teeth

The set of teeth located in the upper jaw.

Space Maintainers

Devices used to hold the space left by a lost primary tooth until the permanent tooth erupts.

Tooth Crown

The visible part of the tooth above the gum line.

Tooth Root

The part of the tooth that is embedded in the jawbone.

Fluorosis

A condition caused by excessive exposure to fluoride, which can affect the appearance of teeth.

Hypoplasia

Underdevelopment of enamel that can lead to an increased risk of cavities.

Anatomical Variations

Differences in tooth shape and formation that can occur among individuals.

Interdental Spaces

The gaps present between adjacent teeth, critical for proper tooth alignment.

Salivary Glands

Glands that produce saliva, playing an essential role in oral health.

Jaw Development

The growth and development of the jaw which influences the eruption sequence of teeth.

Oral Hygiene

Practices that help in maintaining oral health and preventing dental issues.

Dental Check-ups

Regular appointments with a dentist to monitor oral health.

Anesthesia in Dentistry

Use of anesthetics to numb the area during dental procedures.

Orthodontic Treatment

Dental treatment aimed at correcting misaligned teeth and jaws.

Deciduous Incisors

The front primary teeth that are typically smaller and whiter than permanent incisors.

Permanent Canines

The secondary set of canine teeth that replace primary canines.

Supernumerary Teeth

Extra teeth that can erupt in the dental arch beyond the normal number.

Tooth eruption age range

The age periods during which various teeth are expected to emerge.

Interproximal Space

The space between the proximal surfaces of two adjacent teeth.

Permanent Premolars

The teeth that replace the primary molars as part of the permanent dentition.

Dentin Sensitivity

The discomfort experienced due to exposure of dentin, often due to enamel loss.

Feeding Implications

Effects of tooth eruption on feeding and nutrition during early childhood.

Nutritional Considerations

Dietary factors that can impact dental health in children.

Infant Oral Health

Health considerations related to the oral development of infants.

Tooth Wear

The gradual loss of tooth structure due to various factors such as diet and abrasion.

Fluoride Treatments

Topical applications of fluoride to strengthen tooth enamel and prevent decay.

Pediatric Dentistry

A branch of dentistry focused on treating the dental needs of children.

Teething Symptoms

Signs and symptoms experienced by infants as their teeth begin to erupt.

Space Regulation

Management of space between teeth for proper alignment and function.

Crowded Teeth

A dental condition when there isn't enough space for teeth to align properly.

Tooth Eruption Problems

Complications that can arise during the normal eruption process.

Preventive Dentistry

Strategies and practices aimed at preventing dental diseases and conditions.

Dental Implants

Artificial structures used to replace missing teeth.

Restorative Dentistry

Branch of dentistry that focuses on restoring damaged or missing teeth.

Pedodontics

Another term used for pediatric dentistry.

Permanent Dentition

The set of adult teeth that replace primary teeth, typically consisting of 32 teeth.

Eruption Delays

When teeth take longer than expected to emerge.
