Summary
Deep margin elevation (DME) repositions sub-gingival margins coronally. This conservative technique is compatible with periodontal health, though long-term studies are needed.
Area of Science:
- Restorative Dentistry
- Periodontology
Background:
- Deep margin elevation (DME) was introduced to manage sub-gingival margin issues.
- Current dental trends favor conservative approaches, increasing DME's popularity.
Purpose of the Study:
- To review the clinical compatibility of deep margin elevation (DME) with periodontal health.
- To assess the impact of DME on marginal integrity and fracture resistance.
- To compare DME with surgical crown lengthening (SCL) and orthodontic extrusion (OE).
Main Methods:
- A comprehensive literature search was conducted using PubMed, Scopus, and Google Scholar.
- No time restrictions were applied to the article search.
Main Results:
- Well-defined, polished sub-gingival restorations respect biological width and maintain periodontal health.
- Marginal integrity in DME is influenced by adhesive type, restoration material, and layering technique.
- Deep margin elevation does not significantly affect fracture resistance.
Conclusions:
- DME offers a minimally invasive alternative to SCL and OE, respecting biological width.
- Further well-controlled clinical trials are required.
- Long-term follow-up studies are needed to evaluate periodontal outcomes and complication prevention.

Vertical curves are essential in roadway design because they provide smooth transitions between varying roadway grades. Designing vertical curves involves calculating intermediate elevations and identifying the curve's highest or lowest point, which is essential for optimal roadway performance.Intermediate elevations on a vertical curve are determined using the tangent offset method. This method considers the initial elevation at the start of the curve, the grades, and the curve's geometry. The...

01:04Venous Return
5.6K
The circulatory system plays a crucial role in ensuring the optimal functioning of the human body. One of its critical components is venous return - the process that completes the blood circulation cycle. This article will delve into the concept of venous return, how it works, and its significance to our health.
What is Venous Return?
Venous return refers to the rate at which blood flows back to the heart from the body's peripheral veins. It's an integral part of the circulatory system...

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

Trends in nursing are multifactorial and associated with changes in society, within the nursing profession, and in other professions. Notably, telehealth and remote nursing contribute to successful healthcare delivery for numerous patients and help reduce stress for nurses due to nursing shortages. Nurses can reach patients, monitor their conditions, and interact with them using computers, audio, visual accessories, and telephones—for example, remote patient monitoring systems. Likewise,...

Open channel flow, where a fluid flows with a free surface exposed to the atmosphere, is primarily governed by gravitational and surface effects, distinguishing it from closed conduit or pipe flow. In open channels such as rivers, canals, and artificial channels, energy analysis provides valuable insights into flow behavior and the relationship between depth, velocity, and slope.Specific Energy and Flow DepthIn open channel flow, the specific energy, E, combines the gravitational potential...
