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...

Summary

This summary is machine-generated.

Severe dentofacial deformities significantly impair mastication, while mild cases may allow functional adaptation. Objective masticatory evaluation is crucial for accurate diagnosis and timely orthodontic treatment.

Background:

Dentofacial deformities can impact chewing function.
Assessing the severity of malocclusion is essential for determining treatment needs.

Purpose of the Study:

To investigate the relationship between the degree of dentofacial deformity and the extent of masticatory deficiency.
To evaluate masticatory function using objective measures in different groups of young adults with varying degrees of malocclusion.

Main Methods:

Three groups of young adults were studied: severe dentofacial deformity (SevDFD), moderate dentofacial deformity (ModDFD), and no treatment (NoDFD).
Masticatory performance was assessed by analyzing bolus particle size (d50) at deglutition and comparing it to the Masticatory Normative Indicator (MNI).
Index of Treatment Need (IOTN) and Global Oral Health Assessment Index (GOHAI) were also recorded, with statistical analysis using a general linear model and Student-Newman-Keuls test.

Main Results:

Subjects with severe dentofacial deformities (SevDFD) exhibited significantly impaired mastication (d50 mean=7.23mm).
Subjects with moderate dentofacial deformities (ModDFD) showed minimal masticatory impairment (d50 mean=2.54mm) and could adapt functionally.
IOTN scores indicated a need for treatment in both SevDFD and ModDFD groups, but only SevDFD subjects reported unsatisfactory oral health (GOHAI).

Conclusions:

Objective evaluation of masticatory function is vital to differentiate true deficiency from mild impairment that allows adaptation.
Early orthodontic intervention is recommended for malocclusions, as they tend to progress over time.
