Periodontal curettes instrument is designed to remove supragingival calculus from anterior teeth.
What is periodontal curette ?
Periodontal curettes have a rounded back and toe, one face, and one or two cutting edges. They are often the tool of choice for removing supragingival calculi. When doing nonsurgical periodontal therapy as part of a patient's oral hygiene care, universal and Gracey curettes are frequently employed.
What type of instrument is periodontal curette ?
ultrasound instruments The main kind of treatment for eliminating plaque and calculus is ultrasound technology. These power-driven devices oscillate at incredibly fast rates, creating tiny vibrations that help eliminate calculus and subgingival plaque.

Rickets is the disease in children in which an inefficient mineralization of the bone forming tissue causes deformities. This condition results in weak or soft bones in children, normally due to an extreme and prolonged deficiency of vitamin D. Vitamin D promotes the absorption of calcium and phosphorus from the gastrointestinal tract. The symptoms include bowed legs, stunted growth, bone pain, large forehead, and trouble sleeping among others.
Answer:
Failure of chromosome to separate
Explanation:
The main essence of meiotic division is to form daughter cells with a reduced number of chromosomes that will maintain the correct chromosomal number in an organism. This is achieved when chromosomes separate during gamete formation (meiosis) to produce haploid (n) gametes.
However, a case may arise whereby chromosomes fail to separate during the anaphase stage of meiosis. This case is referred to as MEIOTIC NON-DISJUNCTION. As meiosis occurs in two stages i.e. meiosis I and II, so does meiotic nondisjunction. It can occur in meiosis I, where homologous chromosomes fail to separate or meiosis II, where sister chromatids fail to separate.
If it occurs in meiosis I, Two gametes will have a n-1 chromosome number i.e. one chromosome is missing while Two other gametes will have n+1 chromosome number i.e. one extra chromosome is added.
If it occurs in meiosis II, two normal haploid gametes (n) will be produced while the other two will have a n+1 and n-1 chromosome number respectively.
When these abnormal gametes (n+1, n-1) fuses with a normal gamete (n), the resulting organisms possess a chromosomal anomaly called ANEUPLOIDY i.e. a disorder in chromosomal number. The organisms will have 47 and 45 chromosomes depending on whether n+1 or n-1 gametes is involved respectively.
Answer:
By 1795, the warrior chief, Kamehameha the Great, had conquered most of the Hawaiian islands and established a monarchy. In the 1820s, American whalers, traders, and Christian missionaries began to visit and settle in the kingdom of Hawaii.
Although a small minority, the Americans in Hawaii soon owned much of the land, which they began to turn into large sugar-cane plantations. The native Hawaiian population dropped sharply due to smallpox and other diseases that came with the American immigrants. Needing more workers, the sugar planters imported Chinese and Japanese contract laborers who agreed to work on the plantations for a set period of time.
As their influence increased, the Americans became deeply involved with the government of the Hawaiian kings. In 1840, American advisors helped King Kamehameha III produce Hawaii's first written constitution.
By 1842, the United States had developed regular diplomatic relations with Hawaii and supported its status as an independent country. After King David Kalakaua ascended the throne in 1874, Hawaii and the United States signed a trade agreement lifting some restrictions on exporting Hawaiian sugar to the United States. In addition, this agreement permitted the United States to lease a naval station at Pearl Harbor.
