Assessment of the Mouth01:26

Assessment of the Mouth

531
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

1.3K
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

947
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...

Effects of EDTA on End-Point Detection Methods

393
Different methods, such as visual observance of metal-ion indicators, spectroscopic techniques, and potentiometric methods, can determine the endpoint of an EDTA titration.
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a...

Summary
This summary is machine-generated.

Dentists generally accept when to use post and core restorations, but age and experience influence placement decisions. Fibre posts are common due to accessibility and cost.

Area of Science:

  • Dental materials science
  • Restorative dentistry
  • Clinical dentistry

Background:

  • Restoring endodontically treated teeth with posts and cores presents ongoing challenges in dentistry.
  • Understanding current clinical practices and knowledge gaps is crucial for improving treatment outcomes.

Purpose of the Study:

  • To investigate dentists' experience and knowledge regarding the use of post and core systems for restoring endodontically treated teeth.
  • To identify factors influencing the selection and placement of post and core restorations.

Main Methods:

  • A mixed-methods study combining quantitative and qualitative data collection.
  • An online questionnaire with 18 questions was distributed to assess knowledge and practices.
  • A minimum of 93 respondents were required for study validation, with 60% needing to meet a minimum knowledge threshold.

Main Results:

  • 173 dentists completed the questionnaire, with 63% demonstrating proficient knowledge of post and core restorations.
  • Recent graduates were more inclined to adhere to current guidelines.
  • Increasing dentist age correlated with higher numbers of posts placed and greater perceived confidence.

Conclusions:

  • The use of post and core restorations is influenced by clinician age and experience.
  • While general acceptance of indications exists, further research is needed on decision-making drivers and long-term success.
  • Fibre posts are frequently utilized due to their availability and cost-effectiveness.
