Tooth Anatomy01:21

Tooth Anatomy

481
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...

Teeth

433
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...

Porosity in Cement Paste01:18

Porosity in Cement Paste

142
The porosity of concrete is a measure of the void spaces within its structure. These spaces impact its strength and durability significantly. When water and cement interact, a chemical reaction called hydration creates a semi-solid paste. This paste includes combined water, making up approximately 23% of the cement's dry mass, and gel water, which fills minuscule voids known as gel pores, accounting for about 28% of the cement gel volume.
The balance of water to cement in the mix is...

Summary
This summary is machine-generated.

Acellular extrinsic fiber cementum (AEFC) thickness varies by tooth type, root position, and individual factors, with a consistent increase with age and differences between sexes. Functional forces significantly influence AEFC, highlighting its dynamic nature.

Area of Science:

  • Dental Anatomy and Histology
  • Periodontology
  • Biomaterials Science

Background:

  • Continuous cementum apposition occurs throughout life.
  • Masticatory forces and tooth movements can influence cementum thickness.

Purpose of the Study:

  • To investigate acellular extrinsic fiber cementum (AEFC) thickness at four root positions in anterior and posterior teeth.
  • To explore functional aspects, correlations with chronological age, and sex on AEFC thickness.

Main Methods:

  • Undecalcified teeth were sectioned and examined using light microscopy.
  • AEFC thickness was measured at mesial, distal, oral, and vestibular positions in 99 teeth.
  • Mixed-effects models analyzed variations related to tooth type, age, sex, and individual differences.

Main Results:

  • Incisors and canines had the greatest AEFC thickness; premolars had the least.
  • Thickness patterns varied significantly across root positions, tooth types, and dental arches.
  • A linear increase of 1 μm/year in cementum thickness was observed, with females generally showing less thickness than males.

Conclusions:

  • Functional processes strongly influence AEFC thickness patterns across root positions.
  • Sex-specific differences and age-related increases are evident.
  • Individual variability in AEFC thickness is a significant factor.
