Curette
A curette is a surgical instrument designed for scraping or debriding biological tissue or debris in a biopsy, excision, or cleaning procedure. In form, the curette is a small hand tool, often similar in shape to a stylus; at the tip of the curette is a small scoop, hook, or gouge. The verb ''to curette'' means "to scrape with a curette", and curettage ( or ) is treatment that involves such scraping. Uses Some examples of medical use of a curette include: * the removal of impacted ear wax; * dilation and curettage of the uterus, a gynecologic procedure; *excision of many benign tumors and some malignant tumors; * excision of the adenoids ( adenoidectomy) by an otolaryngologist; * to scrape tartar deposits from tooth enamel with a periodontal curette. See also *Ear pick Ear picks, also called ear scoops, or ear spoons, or earpicks, are a type of curette used to clean the ear canal of earwax (cerumen).

Periodontal Curette
The periodontal curette is a type of hand-activated instrument used in dentistry and dental hygiene for the purpose of scaling and root planing.Darby ML, Walsh MM, editors. ''Dental Hygiene: Theory and Practice.'' 4th ed. St. Louis: Saunders/Elsevier; 2015. The periodontal curette is considered a treatment instrument and is classified into two main categories: universal curettes and Gracey curettes. Periodontal curettes have one face, one or two cutting edges and a rounded back and rounded toe. They are typically the instrument of choice for subgingival calculus Calculus, originally called infinitesimal calculus or "the calculus of infinitesimals", is the mathematics, mathematical study of continuous change, in the same way that geometry is the study of shape, and algebra is the study of generalizati ... removal. Universal and Gracey curettes are typically used during nonsurgical periodontal therapy of a patient’s dental hygiene care.Gehrig JS, Willmann DE. ''Foundations of ...

Dilation And Curettage
Dilation (or dilatation) and curettage (D&C) refers to the dilation (widening/opening) of the cervix and surgical removal of part of the lining of the uterus and/or contents of the uterus by scraping and scooping ( curettage). It is a gynecologic procedure used for diagnostic and therapeutic purposes, and is the most commonly used method for first-trimester miscarriage or abortion. D&C normally refers to a procedure involving a curette, also called ''sharp curettage''. However, some sources use the term ''D&C'' to refer to any procedure that involves the processes of dilation and removal of uterine contents, which includes the more common ''suction curettage'' procedures of manual and electric vacuum aspiration. Clinical uses D&Cs may be performed in pregnant and non-pregnant patients, for different clinical indications. During pregnancy or postpartum A D&C may be performed early in pregnancy to remove pregnancy tissue, either in the case of a non-viable pregnancy, such ...

Ear Pick
Ear picks, also called ear scoops, or ear spoons, or earpicks, are a type of curette used to clean the ear canal of earwax (cerumen). They are preferred and are commonly used in East Asia, South Asia and Southeast Asia because Asians tend to develop dry ear wax. In Asia, these are traditionally made from bamboo or precious metals such as silver or gold, but more commonly now, from stainless steel or plastic. European ear scoops produced up to the early 19th century were made from either bronze or precious metals such as silver. Use of ear picks to remove wax is discouraged by some health professionals for fear of damaging the ear and causing infections. It has also been attributed to impacting ear wax into the ear canal, making it more difficult to remove. Types Other than the wide variety of materials used to make them, ear picks vary widely in their tips and embellishments. Disposable plastic ear picks with a cotton swab at one end are increasingly popular. Tips *''Lad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adenoids
In anatomy, the adenoid, also known as the pharyngeal tonsil or nasopharyngeal tonsil, is the superior-most of the tonsils. It is a mass of lymphatic tissue located behind the nasal cavity, in the roof of the nasopharynx, where the nose blends into the throat. In children, it normally forms a soft mound in the roof and back wall of the nasopharynx, just above and behind the uvula. The term ''adenoid'' is also used to represent adenoid hypertrophy, the abnormal growth of the pharyngeal tonsils. Structure The adenoid is a mass of lymphatic tissue located behind the nasal cavity, in the roof of the nasopharynx, where the nose blends into the throat. The adenoid, unlike the palatine tonsils, has pseudostratified epithelium. The adenoids are part of the so-called Waldeyer ring of lymphoid tissue which also includes the palatine tonsils, the lingual tonsils and the tubal tonsils. Development Adenoids develop from a subepithelial infiltration of lymphocytes after the 16th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tooth Enamel
Tooth enamel is one of the four major tissues that make up the tooth in humans and many other animals, including some species of fish. It makes up the normally visible part of the tooth, covering the crown. The other major tissues are dentin, cementum, and dental pulp. It is a very hard, white to off-white, highly mineralised substance that acts as a barrier to protect the tooth but can become susceptible to degradation, especially by acids from food and drink. Calcium hardens the tooth enamel. In rare circumstances enamel fails to form, leaving the underlying dentin exposed on the surface. Features Enamel is the hardest substance in the human body and contains the highest percentage of minerals (at 96%),Ross ''et al.'', p. 485 with water and organic material composing the rest.Ten Cate's Oral Histology, Nancy, Elsevier, pp. 70–94 The primary mineral is hydroxyapatite, which is a crystalline calcium phosphate. Enamel is formed on the tooth while the tooth develops withi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Otolaryngologist
Otorhinolaryngology ( , abbreviated ORL and also known as otolaryngology, otolaryngology–head and neck surgery (ORL–H&N or OHNS), or ear, nose, and throat (ENT)) is a surgical subspeciality within medicine that deals with the surgical and medical management of conditions of the head and neck. Doctors who specialize in this area are called otorhinolaryngologists, otolaryngologists, head and neck surgeons, or ENT surgeons or physicians. Patients seek treatment from an otorhinolaryngologist for diseases of the ear, nose, throat, base of the skull, head, and neck. These commonly include functional diseases that affect the senses and activities of eating, drinking, speaking, breathing, swallowing, and hearing. In addition, ENT surgery encompasses the surgical management of cancers and benign tumors and reconstruction of the head and neck as well as plastic surgery of the face and neck. Etymology The term is a combination of New Latin combining forms ('' oto-'' + '' rhino-'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adenoidectomy
Adenoidectomy is the surgical removal of the adenoid for reasons which include impaired breathing through the nose, chronic infections, or recurrent earaches. The effectiveness of removing the adenoids in children to improve recurrent nasal symptoms and/or nasal obstruction has not been well studied. The surgery is less commonly performed in adults in whom the adenoid is much smaller and less active than it is in children. It is most often done on an outpatient basis under general anesthesia. Post-operative pain is generally minimal and reduced by icy or cold foods. The procedure is often combined with tonsillectomy (this combination is usually called an "adenotonsillectomy" or "T&A"), for which the recovery time is an estimated 10–14 days, sometimes longer, mostly dependent on age. Adenoidectomy is not often performed under one year of age as adenoid function is part of the body's immune system but its contribution to this decreases progressively beyond this age.

Cancer
Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body. These contrast with benign tumors, which do not spread. Possible signs and symptoms include a lump, abnormal bleeding, prolonged cough, unexplained weight loss, and a change in bowel movements. While these symptoms may indicate cancer, they can also have other causes. Over 100 types of cancers affect humans. Tobacco use is the cause of about 22% of cancer deaths. Another 10% are due to obesity, poor diet, lack of physical activity or excessive drinking of alcohol. Other factors include certain infections, exposure to ionizing radiation, and environmental pollutants. In the developing world, 15% of cancers are due to infections such as '' Helicobacter pylori'', hepatitis B, hepatitis C, human papillomavirus infection, Epstein–Barr virus and human immunodeficiency virus (HIV). These factors act, at least partly, by changing the genes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Benign Tumor
A benign tumor is a mass of cells ( tumor) that does not invade neighboring tissue or metastasize (spread throughout the body). Compared to malignant (cancerous) tumors, benign tumors generally have a slower growth rate. Benign tumors have relatively well differentiated cells. They are often surrounded by an outer surface (fibrous sheath of connective tissue) or stay contained within the epithelium. Common examples of benign tumors include moles and uterine fibroids. Some forms of benign tumors may be harmful to health. Benign tumor growth causes a mass effect that can compress neighboring tissues. This can lead to nerve damage, blood flow reduction ( ischemia), tissue death ( necrosis), or organ damage. The health effects of benign tumor growth may be more prominent if the tumor is contained within an enclosed space such as the cranium, respiratory tract, sinus, or bones. For example, unlike most benign tumors elsewhere in the body, benign brain tumors can be life-t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gynaecology
Gynaecology or gynecology (see spelling differences) is the area of medicine that involves the treatment of women's diseases, especially those of the reproductive organs. It is often paired with the field of obstetrics, forming the combined area of obstetrics and gynecology (OB-GYN). The term comes from Greek and means "the science of women". Its counterpart is andrology, which deals with medical issues specific to the male reproductive system. Etymology The word "gynaecology" comes from the oblique stem (γυναικ-) of the Greek word γυνή (''gyne)'' semantically attached to "woman", and ''-logia'', with the semantic attachment "study". The word gynaecology in Kurdish means "jinekolojî", separated word as "jin-ekolojî", so the Kurdish "jin" called like "gyn" and means in Kurdish "woman". History Antiquity The Kahun Gynaecological Papyrus, dated to about 1800 BC, deals with gynaecological diseases, fertility, pregnancy, contraception, etc. The text is divided i ...

Uterus
The uterus (from Latin ''uterus'', plural ''uteri'') or womb () is the organ in the reproductive system of most female mammals, including humans that accommodates the embryonic and fetal development of one or more embryos until birth. The uterus is a hormone-responsive sex organ that contains glands in its lining that secrete uterine milk for embryonic nourishment. In the human, the lower end of the uterus, is a narrow part known as the isthmus that connects to the cervix, leading to the vagina. The upper end, the body of the uterus, is connected to the fallopian tubes, at the uterine horns, and the rounded part above the openings to the fallopian tubes is the fundus. The connection of the uterine cavity with a fallopian tube is called the uterotubal junction. The fertilized egg is carried to the uterus along the fallopian tube. It will have divided on its journey to form a blastocyst that will implant itself into the lining of the uterus – the endometrium ...
