Teeth

1.4K
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...

Tooth Anatomy

1.8K
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...

Summary
This summary is machine-generated.

Orthodontic treatment does not impact long-term caries experience. Good oral hygiene and regular dental visits are key factors for better dental health outcomes, not previous orthodontic interventions.

Area of Science:

  • Dental Public Health
  • Epidemiology
  • Orthodontics

Background:

  • A prospective cohort study analyzed data from a 1988/1989 oral epidemiological study with a 2005/2006 follow-up.
  • Participants completed questionnaires on sociodemographics, dental behaviors, and orthodontic treatment history.
  • Clinical examinations recorded decayed, missing, and filled teeth (DMFT) and occlusal status using the Dental Aesthetic Index (DAI).

Purpose of the Study:

  • To investigate the long-term association between orthodontic treatment and caries experience.
  • To determine if orthodontic treatment influences overall dental health outcomes (DMFT).
  • To identify factors impacting long-term dental disease outcomes.

Main Methods:

  • Prospective cohort study design with data from 1988/89 and 2005/06.
  • Negative binomial regression analysis was used to investigate associations between explanatory variables and dental outcomes.
  • Statistical analysis performed using IBM SPSS Statistics version 24, with p-value set at 0.05.

Main Results:

  • A response rate of 24% (n=448) was achieved for the combined questionnaire and clinical examination.
  • Regular tooth brushing (at least twice daily) was associated with fewer decayed and missing teeth (p <0.001).
  • Orthodontic treatment showed no statistically significant association with DMFT in adjusted models, but increased missing teeth in most DAI categories.

Conclusions:

  • Caries experience is not correlated with previous orthodontic treatment.
  • Sociodemographic variables and dental health behaviors significantly impact long-term dental disease outcomes.
  • Orthodontic treatment does not provide superior long-term dental health outcomes concerning caries.
