Teeth

1.9K
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...

Assessment of the Mouth01:26

Assessment of the Mouth

1.3K
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.

Tooth Anatomy01:21

Tooth Anatomy

2.4K
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...

Oral Cavity01:11

Oral Cavity

3.4K
The oral cavity, or the mouth, is a complex structure in humans that plays a vital role in our day-to-day lives. Its role is not only in chewing and swallowing food; it also plays a role in speech and facial expressions.
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...

Summary
This summary is machine-generated.

Cleft lip severity influences tooth development patterns in children. More detailed cleft lip (CL) classifications correlate with specific lateral incisor positions, aiding understanding of odontogenesis.

Area of Science:

  • Dentistry
  • Oral and Maxillofacial Surgery
  • Genetics

Background:

  • Oral clefts (CL) significantly impact tooth development but the precise relationship remains unclear.
  • Understanding CL subphenotypes and their association with dentition patterns is crucial for clinical relevance.

Purpose of the Study:

  • To investigate if varying cleft lip (CL) severities exhibit distinct dentition patterns.
  • To determine the clinical relevance of a more detailed classification of incomplete CL.

Main Methods:

  • Retrospective analysis of 345 children with nonsyndromic unilateral cleft lip with or without alveolus (CL ± A) and cleft lip, alveolus, and palate (CLAP).
  • Assessment of associations between CL subphenotypes and five lateral incisor patterns (normal, anterior, posterior, split, agenesis).
  • Multinomial logistic regression models were employed for statistical analysis.

Main Results:

  • Children with milder CL (vermillion notch to two-thirds) were more likely to have deciduous pattern x and permanent pattern X.
  • Those with two-thirds to subtotal CL predominantly showed deciduous pattern xy and permanent pattern X.
  • Complete CL cases most frequently exhibited deciduous pattern y and permanent pattern AB (agenesis).

Conclusions:

  • A detailed subdivision of CL morphology (vermillion notch to two-thirds, two-thirds to subtotal, complete) is clinically relevant.
  • Specific CL subphenotypes are strongly associated with distinct lateral incisor patterns.
  • Factors critical to CL pathogenesis also appear critical for odontogenesis.
