... is inflammation of the alveolar bone (i.e., the alveolar process of the maxilla or mandible). Classically, this occurs as a postoperative complication of tooth extraction. Alveolar osteitis usually occurs where the blood clot fails to form or is lost from the socket (i.e., the defect left in the gum when a tooth is taken out). This leaves an empty socket where bone is exposed to the oral cavity, causing a localized alveolar osteitis limited to the lamina dura (i.e., the bone which lines the socket). This specific type of alveolar osteitis is also known as dry socket or, less commonly, fibrinolytic alveolitis, and is associated with increased pain and delayed healing time. Dry socket occurs in about 0.5-5% of routine dental extractions, and in about 25-30% of extractions of impacted mandibular third molars (wisdom teeth which are buried in the bone). Since dry socket ...

... (from the Greek peri, "around", Latin corona "crown" and -itis, "inflammation") also known as operculitis, is inflammation of the soft tissues surrounding the crown of a partially erupted tooth, including the gingiva (gums) and the dental follicle. The soft tissue covering a partially erupted tooth is known as an operculum, an area which can be difficult to access with normal oral hygiene methods. The synonym operculitis technically refers to inflammation of the operculum alone. Pericoronitis is caused by an accumulation of bacteria and debris beneath the operculum, or by mechanical trauma (e.g. biting the operculum with the opposing tooth). Pericoronitis is often associated with partially erupted and impacted mandibular third molars (lower wisdom teeth), often occurring at the age of wisdom tooth eruption (15-24). Other common causes ...

... , also known as dental pain, is pain in the teeth and/or their supporting structures, caused by dental diseases or pain referred to the teeth by non-dental diseases. Common causes include inflammation of the pulp, usually in response to tooth decay, dental trauma, or other factors, dentin hypersensitivity (short, sharp pain, usually associated with exposed root surfaces), apical periodontitis (inflammation of the periodontal ligament and alveolar bone around the root apex), dental abscesses (localized collections of pus, such as apical abscess, pericoronal abscess, and periodontal abscess), alveolar osteitis ("dry socket", a possible complication of tooth extraction, with loss of the blood clot and exposure of bone), acute necrotizing ulcerative gingivitis (a gum infection, also called "trenchmouth"), temporomandibular disorder and others. Pulpitis is classified as reversible when the ...

An oilseed press is a machine that lies at the center of vegetable oil extraction. This is due to the fact that this technology is designed to release oil from oilseeds. Multiple oilseed press layouts have been developed over time to complete this process, with each having its own distinct set of advantages and disadvantages. Moreover, the products that are created by oilseed presses, namely oil and oilseed meal, possess great nutritive benefits for humans and livestock respectively. The oilseed press, being at the center of the oil-extraction process, is joined with various other pieces of equipment and procedures that form a pre- and post-extraction system. Breaking it down to its simplest formulation, the process that oilseed presses carry out appears is quite simple. Oilseed presses essentially extrude or 'press' vegetable oil from oil-bearing seeds, which include soybean, sunflower, peanut, safflower, canola, sesame, niger, castor bean, linseed, ...

Socket preservation or alveolar ridge preservation (ARP)[1] is a procedure to reduce bone loss after tooth extraction to preserve the dental alveolus (tooth socket) in the alveolar bone. A platelet-rich fibrin (PRF)[2] membrane containing bone growth enhancing elements can be stitched over the wound or a graft material or scaffold is placed in the socket of an extracted tooth.[3][4] The socket is then directly closed with stitches or covered with a non-resorbable or resorbable membrane and sutured.[5]. ...

... /mɛˈpɪvəkeɪn/ is a local anesthetic of the amide type. Mepivacaine has a reasonably rapid onset (more rapid than that of procaine) and medium duration of action (shorter than that of procaine) and is marketed under various trade names including Carbocaine and Polocaine. Mepivacaine became available in the United States in the 1960s. Mepivacaine is used in any infiltration and regional anesthesia. It is supplied as the hydrochloride salt of the racemate, which consists of R(-)-mepivacaine and S(+)-mepivacaine in equal proportions. These two enantiomers have markedly different pharmacokinetic properties. Porto GG, Vasconcelos BC, Gomes AC, Albert D (January 2007).

... , also called lockjaw, is reduced opening of the jaws (limited jaw range of motion). It may be caused by spasm of the muscles of mastication or a variety of other causes. Temporary trismus occurs much more frequently than permanent trismus. It is known to interfere with eating, speaking, and maintaining proper oral hygiene. This interference, specifically with the patient's ability to swallow properly, results in an increased risk of aspiration. In some instances, trismus presents with altered facial appearance. The condition may be distressing and painful for the patient. Examination and treatments requiring access to the oral cavity can be limited, or in some cases impossible, due to the nature of the condition itself. Trismus is defined as difficulty in opening the mouth due to a muscle spasm resulting from a disturbance in the trigeminal nerve, however it can also refer to limited mouth opening of any cause. Another definition of trismus is simply a limitation of movement. ...

... (also termed tooth staining) is abnormal tooth color, hue or translucency. External discoloration is accumulation of stains on the tooth surface. Internal discoloration is due to absorption of pigment particles into tooth structure. Sometimes there are several different co-existent factors responsible for discoloration. The appearance and perception of a tooth is the result of a complex interaction of factors such as lighting conditions, translucency, opacity, light scattering, gloss and the human eye and brain. Of these, the intrinsic pigmentation of a tooth is the most influential, which in turn is determined by genetic and natural factors. Light hitting a tooth undergoes reflection, absorption and transmission by varying degrees in each tissue layer of the ...

A tooth (plural teeth) is a hard, calcified structure found in the jaws (or mouths) of many vertebrates and used to break down food. Some animals, particularly carnivores, also use teeth for hunting or for defensive purposes. The roots of teeth are covered by gums. Teeth are not made of bone, but rather of multiple tissues of varying density and hardness. The cellular tissues that ultimately become teeth originate from the embryonic germ layer, the ectoderm. The general structure of teeth is similar across the vertebrates, although there is considerable variation in their form and position. The teeth of mammals have deep roots, and this pattern is also found in some fish, and in crocodilians. In most teleost fish, however, the teeth are attached to the outer surface of the bone, while in lizards they are ...

Before the treatment, the clinician should examine the patient: taking a health and dental history (including allergies and sensitivities), observe hard and soft tissues, placement and conditions of restorations, and sometimes x-rays to determine the nature and depth of possible irregularities. If this is not completed prior to the whitening agents being applied to the tooth surface, excessive sensitivity and other complications may occur. The whitening shade guides are used to measure tooth colour. These shades determine the effectiveness of the whitening procedure, which may vary from two to seven shades.[33] These shades may be reached after a single in office appointment, or may take longer, depending on the individual. The effects of bleaching can last for several months, but may vary depending on the lifestyle of the patient. Consuming tooth staining foods or drinks that have a strong colour may ...

... 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. Enamel is the hardest substance in the human body and contains the highest percentage of minerals, 96%, with water and organic material composing the rest. The primary mineral is hydroxyapatite, which is a crystalline calcium phosphate. Enamel is formed on the tooth while the tooth is developing within the gum, before it erupts into the mouth. Once fully formed, it does not contain blood ...

... often wear in specific patterns, based on the way the horse eats its food, and these patterns are often used to conjecture on the age of the horse after it has developed a full mouth. As with aging through observing tooth eruption, this can be imprecise, and may be affected by diet, natural abnormalities, and vices such as cribbing. The importance of dentition in assessing the age of horses led to veterinary dentistry techniques being used as a method of fraud, with owners and traders altering the teeth of horses to mimic the tooth shapes and characteristics of horses younger than the actual age of the equine.[3]. Equine teeth are designed to wear against the tooth above or below as the horse chews, thus preventing excess growth. The upper jaw is wider than the lower one. In some cases, sharp edges can occur on the outside of the upper molars and the inside of the lower ...
