Tooth Anatomy01:21

Tooth Anatomy

2.0K
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...

Restorative Care01:19

Restorative Care

2.3K
Restorative care is provided once a patient has been discharged from a healthcare facility and requires additional services. The additional services include home care, rehabilitation programs, and extended care. Restorative care centers help the patient regain their previous level of functioning or acquire a new level of functioning due to the incapacitating effects of a disease or a disability. It aims to assist patients in enhancing their quality of life by encouraging independence,...

Teeth

1.6K
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...

Veneer01:19

Veneer

330
Veneer refers to a thin sheet of wood, typically produced to a thickness of about one-eighth of an inch or less. This material is crafted through various methods, the most common being rotary cutting. In this process, a log is mounted into a large lathe and spun against a knife edge, peeling off a continuous strip of wood as the knife penetrates deeper into the rotating log, creating a rotary-cut veneer.
Other veneering techniques include plain-slicing, quarter-slicing, and rift-slicing. These...

Summary

Fluoride-releasing dental materials like Activa Restorative significantly reduced secondary caries compared to non-fluoride materials. Activa Restorative demonstrated superior performance in limiting lesion depth and wall lesions on both enamel and root surfaces.

Area of Science:

  • Dental Materials Science
  • Cariology
  • Restorative Dentistry

Background:

  • Secondary caries remains a significant challenge in restorative dentistry.
  • Evaluating the anticariogenic potential of restorative materials is crucial for improving clinical outcomes.

Purpose of the Study:

  • To assess the laboratory efficacy of fluoride-releasing restorative materials in reducing secondary caries.
  • To compare the secondary caries inhibition of Activa Restorative and Beautifil Giomer against controls.

Main Methods:

  • Class V cavities were prepared in 20 maxillary molars and restored with Filtek Bulk Fil, Equia Forte, Beautifil Giomer, or Activa Restorative.
  • Restored teeth underwent thermal cycling and demineralization to induce artificial caries.
  • Lesion depth and wall lesion frequency were quantified using polarized light microscopy and statistical analysis.

Main Results:

  • Filtek Bulk Fil showed significantly higher lesion depths and wall lesion frequencies compared to all other groups.
  • Activa Restorative exhibited significantly lower lesion depths and wall lesion frequencies on both enamel and root surfaces than Equia Forte and Beautifil Giomer.
  • All tested restorative materials demonstrated some reduction in lesion progression compared to the negative control.

Conclusions:

  • Fluoride release from restorative materials contributes to secondary caries reduction.
  • Activa Restorative demonstrated superior anticariogenic properties compared to Equia Forte glass-ionomer and Beautifil Giomer in laboratory conditions.
  • These findings suggest Activa Restorative may offer enhanced protection against secondary caries progression.
