Oral Hygiene

Oral Hygiene:

Oral hygiene is the precaution from the teeth problems and mouth health issues.  It is the practice of keeping the mouth and teeth clean to prevent dental problems. The most common problems are dental cavities, gingivitis, and bad breath. There are also oral pathologic conditions in which good oral hygiene is required, the conditions includes gingivitis, periodontitis, and dental trauma, such as subluxation, oral cysts, and following wisdom tooth extraction.

Teeth cleaning is the best way for the removal of dental plaque and tartar from teeth to prevent cavities, gingivitis, and gum disease.  Almost all gum disease causes at least one-third of adult tooth loss. Tooth decay is the most common global disease. More than eighty present of cavities occur inside pits and fissures on chewing surfaces where brushing cannot reach food left trapped after every meal or snack, and saliva or fluoride have no access to neutralise acid and remineralise demineralised teeth, unlike easy-to-reach surfaces, where fewer cavities occur.

Vector Biology:

Vector Biology is also called as molecular biology. In molecular cloning, a vector is simply a DNA molecule that is used as a vehicle to carry foreign genetic material into another cell, where it can be replicated and expressed (replicated or expressed). A vector containing foreign DNA is called as recombinant DNA. There are four major types of vectors. The types of vectors include plasmids, viral vectors, cosmids, and artificial chromosomes. The engineered vectors are an origin of replication, a multicloning site, and a selectable marker.

The vector is a DNA sequence that consists of an insert and a larger sequence that serves as the “backbone” of the vector. The purpose of a vector which transfers genetic information to another cell is typically to isolate, multiply, or express the insert in the target cell.
