|March 2, 2018
Summary
A modified tunnel technique using a double layer of acellular dermal matrix (ADM) successfully treated adjacent gingival recession defects. This approach preserved the patient's natural gingival pigmentation, achieving both root coverage and aesthetic goals.
Area of Science:
- Periodontology
- Regenerative Dentistry
Background:
- Gingival recession defects often require surgical intervention.
- Preserving natural gingival pigmentation during treatment is a significant aesthetic concern for patients.
- Conventional techniques may compromise pigmented tissues.
Observation:
- A patient presented with multiple adjacent gingival recession sites with existing natural pigmentation.
- The patient desired preservation of their natural gingival color.
- A modified tunnel surgical technique was selected to minimize trauma to pigmented areas.
Findings:
- A double layer of acellular dermal matrix (ADM) was utilized as a graft material.
- The gingival complex was repositioned coronally.
- Successful root coverage and complete preservation of natural gingival pigmentation were achieved.
Implications:
- The modified tunnel technique with double-layer ADM is effective for treating adjacent gingival recession.
- This technique offers a viable solution for preserving natural gingival pigmentation during periodontal plastic surgery.
- It enhances aesthetic outcomes in patients with specific pigmentation concerns.

The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

01:32What is Natural Selection?
129.8K
Natural selection is an evolutionary process in which individuals with survival-promoting traits reproduce at higher rates. These favorable traits become more common within a population or species. Naturally selected traits initially arise via random genetic mutations. In order for selection to occur, there must be variation within a population, the trait controlling the variation must be heritable, and there must be an evolutionary advantage for variation in the trait.

01:10Nature and Nurture
22.4K
Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience,...

Lumber defects, which can affect both the appearance and structural integrity of wood, include a variety of growth and manufacturing flaws. Growth defects such as knots and knotholes occur where branches were once attached to the tree trunk, with knotholes forming when these knots fall out. Other natural defects include decay and insect damage, which compromise the wood's strength and durability.

Chirality is the most intriguing yet essential facet of nature, governing life’s biochemical processes and precision. It can be observed from a snail shell pattern in a macroscopic world to an amino acid, the minutest building block of life. Most of the snails around the world have right-coiled shells because of the intrinsic chirality in their genes. All the amino acids present in the human body exist in an enantiomerically pure state, except for glycine - the sole achiral amino acid.
