Tooth Anatomy

Tooth Anatomy

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...

Teeth

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

Area of Science:

Dentistry
Endodontics
Oral Surgery

Background:

Gemination, a rare dental anomaly, involves the incomplete division of a single tooth germ, potentially leading to complex clinical presentations.
Dental trauma during primary dentition can influence the development of permanent teeth, predisposing to anomalies like gemination and dilaceration.
Maxillary lateral incisors are susceptible to developmental disturbances, necessitating thorough diagnostic evaluation when esthetic or functional issues arise.

Observation:

A 16-year-old male presented with esthetic and functional complaints related to a maxillary left lateral incisor, with a history of trauma to primary anterior teeth.
Clinical examination revealed altered esthetics and function, with positive response to percussion and negative pulp vitality test, indicative of pulpal pathology.
Cone-beam computed tomography (CBCT) confirmed tooth gemination, crown-root dilaceration, the presence of two root canals, and periapical bone rarefaction.

Findings:

Endodontic treatment involved instrumentation with Reciproc R40, irrigation with 1% sodium hypochlorite (NaOCl), and obturation using lateral condensation with gutta-percha and AH Plus sealer.
The treated tooth was restored with composite resin, successfully improving esthetics and function.
A 6-month follow-up demonstrated the absence of clinical symptoms and radiographic evidence suggesting apical healing.

Implications:

This case highlights the importance of CBCT in diagnosing complex dental anomalies like gemination with dilaceration and multiple root canals.
Successful endodontic management and restoration of geminated teeth can restore function and esthetics, improving patient quality of life.
Understanding the long-term outcomes of endodontically treated geminated teeth is crucial for predicting prognosis and guiding clinical decision-making.
