Summary
Deep margin elevation (DME) is a conservative dental technique for restoring deep cavities. While promising for periodontal health, further clinical trials are needed to confirm its long-term effectiveness and safety.
Area of Science:
- Restorative Dentistry
- Periodontology
Background:
- Deep proximal lesions pose restorative challenges.
- Traditional approaches may compromise tooth structure or periodontal health.
Purpose of the Study:
- To review the literature on deep margin elevation (DME) as a conservative restorative technique.
- To evaluate the impact of DME on marginal adaptation, biomechanical properties, and periodontal health.
Main Methods:
- Comprehensive literature search from January 1998 to November 2021 across major databases (PubMed, Ovid, Scopus, Cochrane, Semantic Scholar).
- Inclusion and exclusion criteria were applied to select relevant research articles.
- Focus on studies investigating materials, adhesive systems, and clinical outcomes of DME.
Main Results:
- Elevation material and adhesive system influence marginal adaptation.
- DME does not negatively impact bond strength, fatigue behavior, fracture resistance, failure patterns, or repairability.
- Well-polished DME and subgingival restorations are compatible with periodontal health.
Conclusions:
- Deep margin elevation is a viable technique with potential benefits for periodontal health.
- Current evidence is primarily from in vitro studies, necessitating randomized clinical trials with long-term follow-up.
- Cautious application of DME is recommended, emphasizing field isolation, matrix seal, and respecting biological width.

01:19Design Example: Maintaining Level of an Embankment
150
Constructing a roadway embankment over uneven terrain requires precise leveling to ensure stability and proper drainage. Surveyors use a leveling instrument and staff to calculate ground elevations and determine the required fill material at each point along the embankment alignment.The process begins by positioning a leveling instrument near a benchmark with a known elevation. A backsight reading establishes the instrument height, which serves as a reference for subsequent measurements. A...

01:27Margin of Error
4.6K
The margin of error is also called the maximum error of an estimate. The margin of error is the maximum possible or expected difference between the observed sample parameter value and the actual population parameter value. For proportion, it is the maximum difference between the value of sample proportion obtained from the data and the true value of population proportion. As the true value of the population parameter is not known, the margin of error is calculated using the sample statistic.

135
Topography involves measuring and mapping land elevations, natural features, and artificial structures to create accurate representations of the terrain. Topographic surveying relies on traditional and modern methods, each with distinct advantages and limitations.Traditional Surveying Methods:Transit stadia surveys and plane table surveys were widely used traditional surveying methods. These techniques relied on instruments like theodolites and stadia rods for measuring distances and angles,...

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...

01:26Profile Leveling and Cross Sections
737
Profile leveling and cross-sections are surveying methods used to determine and document terrain elevations for infrastructure projects such as highways, railroads, canals, and pipelines. These methods provide data for earthwork planning and alignment of proposed routes. Profile leveling involves measuring elevations along a fixed line to create a vertical terrain profile. A surveyor sets up a leveling instrument at the benchmark (BM) and records a backsight (BS) to determine the...

Differential leveling is a precise method in surveying used to determine the elevation difference between two points. Its primary goal is to establish accurate vertical measurements to create level surfaces or grade lines critical for designing and constructing infrastructures such as roads, bridges, and buildings.The procedure for differential leveling begins with setting up and leveling the instrument at a point where the benchmark can be seen. The level rod is held on the benchmark (BM), and...
