Muscles for Facial Expressions

5.7K
The craniofacial muscles are a collection of approximately 20 thin skeletal muscles situated beneath the skin of the face and scalp. These muscles, primarily responsible for the vast array of human facial expressions, originate from the bones or fibrous structures of the skull and extend outwards to connect with the skin. While most skeletal muscles in the body are enveloped in thick fascia, facial muscles generally have a more delicate fascial covering, with the buccinator muscle being a...

Teeth

2.2K
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

2.8K
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

Evaluating esthetic restorative materials for primary molars, this study found CAD/CAM crowns offer superior marginal accuracy. Zirconia crowns excelled in marginal adaptation, while hybrid ceramics demonstrated better fracture resistance.

Area of Science:

  • Dental Materials Science
  • Restorative Dentistry
  • Pediatric Dentistry

Background:

  • Growing demand for esthetic restorative materials in pediatric dentistry.
  • Need to evaluate marginal accuracy and fracture resistance of materials for primary molars.
  • Ensuring optimal clinical outcomes for pediatric restorative procedures.

Purpose of the Study:

  • Assess vertical marginal gap distance of esthetic restorative materials.
  • Evaluate fracture resistance of esthetic restorative materials after cyclic loading.
  • Compare different types of crowns for primary molar restorations.

Main Methods:

  • Forty extracted primary molars were divided into four groups: stainless steel veneered, prefabricated monolithic zirconia, CAD/CAM zirconia, and hybrid ceramic CAD/CAM crowns.
  • Vertical marginal gap distance measured using a stereomicroscope.
  • Fracture resistance evaluated via cyclic loading.

Main Results:

  • CAD/CAM crowns showed significantly better marginal gap distances than prefabricated crowns (p < 0.001).
  • Yttria-partially stabilized zirconia CAD/CAM crowns exhibited the highest fracture resistance (2018.5 ± 236.0 N).
  • Hybrid ceramic CAD/CAM crowns demonstrated the smallest marginal gap (86.7 μm).

Conclusions:

  • CAD/CAM zirconia crowns offer excellent marginal adaptation for primary molars.
  • Hybrid ceramic CAD/CAM crowns show superior fracture resistance.
  • Both zirconia and hybrid ceramics are promising esthetic restorative options for primary molars.
