Summary
This case study details the complex dental anomalies in a child, including missing and extra teeth, and their successful multidisciplinary management. Early detection and coordinated care are crucial for optimal outcomes in rare dental conditions.
Area of Science:
- Dentistry
- Oral and Maxillofacial Surgery
- Orthodontics
Background:
- Describes a rare case of concomitant hypodontia and hyperdontia.
- Highlights a non-syndromic 8-year-old patient with gemination, missing mandibular lateral incisors, supplemental maxillary canines, ankyloglossia, and hyperplastic frena.
Purpose of the Study:
- To present the multidisciplinary management of complex, concurrent dental anomalies.
- To emphasize the importance of early detection and coordinated care in such cases.
Main Methods:
- Utilized panoramic imaging and cone beam computed tomography (CBCT) for diagnosis.
- Performed surgical extraction of supernumerary teeth and frenectomies under general anesthesia.
- Initiated maxillary expansion with a Hyrax appliance and prophylactic resin restoration for a geminated tooth.
Main Results:
- Restored tongue mobility and improved plaque control through frenectomies.
- Preserved arch integrity with resin restoration of a geminated tooth.
- Initiated orthodontic interception for complex dental anomalies.
Conclusions:
- Managing concurrent numerical and structural dental anomalies requires early detection and advanced imaging.
- A coordinated, multi-specialty approach is essential for effective treatment.
- Intervention should focus on restoring function and preventing secondary complications like malocclusion.

01:15Teeth
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 and...

01:21Tooth 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 grinding food.

01:26Assessment of the Mouth
A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
