Necrotizing Periodontal Diseases
Necrotizing periodontal diseases is one of the three categories of periodontitis as defined by the American Academy of Periodontology/ European Federation of Periodontology 2017 World Workshop classification system. Necrotizing periodontal diseases are a type of inflammatory periodontal (gum) disease caused by bacteria (notably fusobacteria and spirochaete species). The diseases appear to represent different severities or stages of the same disease process, although this is not completely certain. These diseases usually have a sudden onset. The mildest on the spectrum is necrotizing gingivitis (NG), followed by the successively more severe conditions necrotizing periodontitis (NP), necrotizing stomatitis and finally cancrum oris (noma), which is frequently fatal. Necrotizing gingivitis Necrotizing gingivitis, is a common, non-contagious infection of the gums. If improperly treated necrotizing may become chronic and/or recurrent. In developed countries, necrotizing gingivi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Periodontology
Periodontology or periodontics (from Ancient Greek , – 'around'; and , – 'tooth', genitive , ) is the Specialty (dentistry), specialty of dentistry that studies supporting structures of Tooth, teeth, as well as diseases and conditions that affect them. The supporting tissues are known as the periodontium, which includes the gingiva (gums), Alveolar process, alveolar bone, cementum, and the periodontal ligament. A periodontist is a dentist that specializes in the prevention, diagnosis and treatment of periodontal disease and in the placement of dental implants. The periodontium The term ''periodontium'' is used to describe the group of structures that directly surround, support and protect the teeth. The periodontium is composed largely of the gingival tissue and the supporting bone. Gingivae Normal gingiva may range in color from light coral pink to heavily pigmented. The soft tissues and connective fibres that cover and protect the underlying cementum, periodontal lig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psychological Stress
In psychology, stress is a feeling of emotional strain and pressure. Stress is a form of psychological and mental discomfort. Small amounts of stress may be beneficial, as it can improve athletic performance, motivation and reaction to the environment. Excessive amounts of stress, however, can increase the risk of strokes, heart attacks, ulcers, and mental illnesses such as depression and also aggravate pre-existing conditions. Psychological stress can be external and related to the environment, but may also be caused by internal perceptions that cause an individual to experience anxiety or other negative emotions surrounding a situation, such as pressure, discomfort, etc., which they then deem stressful. Hans Selye (1974) proposed four variations of stress. On one axis he locates good stress ( eustress) and bad stress (distress). On the other is over-stress (hyperstress) and understress (hypostress). Selye advocates balancing these: the ultimate goal would be to balance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bleeding On Probing
Bleeding on probing (BoP) which is also known as bleeding gums or gingival bleeding is a term used by dentists and dental hygienists when referring to bleeding that is induced by gentle manipulation of the tissue at the depth of the gingival sulcus, or interface between the gingiva and a tooth. BoP is a sign of periodontal inflammation and indicates some sort of destruction and erosion to the lining of the sulcus or the ulceration of sulcular epithelium. The blood comes from lamina propria after the ulceration of the lining.Gingival bleeding' URL assessed on November 21, 2009 BoP seems to be correlated with Periodontal Inflamed Surface Area (PISA). Causes There are many possible causes of gingival bleeding. The main cause of gingival bleeding is the formation and accumulation of plaque at the gum line due to improper brushing and flossing of teeth. The hardened form of plaque is calculus. An advanced form of gingivitis as a result of formation of plaque is periodontitis. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interdental Papilla
The interdental papilla, also known as the interdental gingiva, is the part of the gums (gingiva) that exists coronal to the free gingival margin on the mesial and distal surfaces of the teeth. The interdental papillae fill in the area between the teeth apical to their contact areas to prevent food impaction; they assume a conical shape for the anterior teeth and a blunted shape buccolingually for the posterior teeth. A missing papilla is often visible as a small triangular gap between adjacent teeth. Dentists will sometimes refer to this gap as a ' black triangle'. It can sometimes be corrected with orthodontic treatment. The relationship of interdental bone to the interproximal contact point between adjacent teeth is a determining factor in whether the interdental papilla will be present. If a distance greater than 8 mm exists between the interdental bone and the interproximal contact, usually no papilla will be present. If the distance is 5 mm or less, then a papil ...

Ulcer
An ulcer is a discontinuity or break in a bodily membrane that impedes normal function of the affected organ. According to Robbins's pathology, "ulcer is the breach of the continuity of skin, epithelium or mucous membrane caused by sloughing out of inflamed necrotic tissue." Common forms of ulcers recognized in medicine include: * Ulcer (dermatology), a discontinuity of the skin or a break in the skin. ** Pressure ulcers, also known as bedsores ** Genital ulcer, an ulcer located on the genital area ** Ulcerative dermatitis, a skin disorder associated with bacterial growth often initiated by self-trauma ** Anal fissure, an ulcer or tear near the anus or within the rectum ** Diabetic foot ulcer, a major complication of the diabetic foot * Callous ulcer, a chronic nonhealing ulcer with hard indurated base and inelastic margins * Corneal ulcer, an inflammatory or infective condition of the cornea * Mouth ulcer, an open sore inside the mouth. ** Aphthous ulcer, a specific ...

Necrosis
Necrosis () is a form of cell injury which results in the premature death of cells in living tissue by autolysis. The term "necrosis" came about in the mid-19th century and is commonly attributed to German pathologist Rudolf Virchow, who is often regarded as one of the founders of modern pathology. Necrosis is caused by factors external to the cell or tissue, such as infection, or trauma which result in the unregulated digestion of cell components. In contrast, ''apoptosis'' is a naturally occurring programmed and targeted cause of cellular death. While apoptosis often provides beneficial effects to the organism, necrosis is almost always detrimental and can be fatal. Cellular death due to necrosis does not follow the apoptotic signal transduction pathway, but rather various receptors are activated and result in the loss of cell membrane integrity and an uncontrolled release of products of cell death into the extracellular space. This initiates an inflammatory response in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orthodontics
Orthodontics (also referred to as orthodontia) is a dentistry specialty that addresses the diagnosis, prevention, management, and correction of mal-positioned teeth and jaws, as well as misaligned bite patterns. It may also address the modification of facial growth, known as dentofacial orthopedics. Abnormal alignment of the teeth and jaws is very common. The approximate worldwide prevalence of malocclusion was as high as 56%. However, conclusive evidence-based medicine, scientific evidence for the Health benefit (medicine), health benefits of orthodontic treatment is lacking, although patients with completed treatment have reported a higher quality of life than that of untreated patients undergoing orthodontic treatment. The main reason for the prevalence of these malocclusions is diets with less fresh fruit and vegetables and overall softer foods in childhood, causing smaller jaws with less room for the teeth to erupt. Treatment may require several months to a few years and enta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White People
White is a Race (human categorization), racial classification of people generally used for those of predominantly Ethnic groups in Europe, European ancestry. It is also a Human skin color, skin color specifier, although the definition can vary depending on context, nationality, ethnicity and point of view. Description of populations as "White" in reference to their skin color is occasionally found in Greco-Roman ethnography and other ancient or medieval sources, but these societies did not have any notion of a White race or pan-European identity. The term "White race" or "White people", defined by their light skin among other physical characteristics, entered the major European languages in the later seventeenth century, when the concept of a "unified White" achieved greater acceptance in Europe, in the context of racialization, racialized slavery and social status in the European colonies. Scholarship on Race (human categorization), race distinguishes the modern concept from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tobacco
Tobacco is the common name of several plants in the genus '' Nicotiana'' of the family Solanaceae, and the general term for any product prepared from the cured leaves of these plants. More than 70 species of tobacco are known, but the chief commercial crop is ''N. tabacum''. The more potent variant ''N. rustica'' is also used in some countries. Dried tobacco leaves are mainly used for smoking in cigarettes and cigars, as well as pipes and shishas. They can also be consumed as snuff, chewing tobacco, dipping tobacco, and snus. Tobacco contains the highly addictive stimulant alkaloid nicotine as well as harmala alkaloids. Tobacco use is a cause or risk factor for many deadly diseases, especially those affecting the heart, liver, and lungs, as well as many cancers. In 2008, the World Health Organization named tobacco use as the world's single greatest preventable cause of death. Etymology The English word 'tobacco' originates from the Spanish word ''taba ...
