Insights

Tongue-base position influences craniofacial growth in preschool children. This study found correlations between tongue posture and facial development, impacting maxillo-mandibular growth even at a young age.

Area of Science:

  • Pediatric Dentistry
  • Craniofacial Morphology
  • Orthodontics

Background:

  • Tongue-base position is a critical factor in craniofacial development.
  • Understanding early influences on jaw growth is essential for timely intervention.

Purpose of the Study:

  • To investigate the association between tongue-base position and craniofacial morphology in preschool children.
  • To determine if age and sex influence these relationships.

Main Methods:

  • Lateral cephalometric radiographs were used to analyze craniofacial structures.
  • Measurements included posterior facial height, nasal floor length, mandibular corpus length, and tongue-base position.
  • Statistical analysis was performed to identify correlations.

Main Results:

  • No significant sex-based differences were observed in the measurements.
  • Tongue-base position, posterior facial height, nasal floor length, and mandibular corpus length all showed positive correlations with age.
  • Tongue-base position was significantly correlated with maxillary position, vertical mandibular rotation, and nasopharyngeal airway space.

Conclusions:

  • Tongue-base position significantly influences maxillo-mandibular growth in preschool children.
  • Early identification of tongue posture can aid in predicting and managing craniofacial development.
  • These findings highlight the importance of evaluating tongue posture in pediatric dental assessments.

Assessment of the Mouth01:26

Assessment 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.
Tongue01:01

Tongue

The human tongue is a fascinating and complex organ, responsible for various essential functions such as swallowing, speech, and taste. It is also subject to various conditions and diseases. In this article, we delve into the anatomy of the tongue, its roles, and some common conditions that can affect it.
Anatomical Position in the Oral Cavity
The tongue is located within the oral cavity, also known as the mouth. It is attached to the floor of the mouth by a fold of mucous membrane called the...
Teeth01:15

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 and...
Overview of the Skull01:08

Overview of the Skull

The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain. It is subdivided into the facial bones and the brain case, or cranial vault. The facial bones underlie the facial structures, form the nasal cavity, enclose the eyeballs, and support the teeth of the upper and lower jaws.
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...
Sutures of the Skull01:22

Sutures of the Skull

The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
Language Development01:22

Language Development

Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...
