Parulis
An intraoral dental sinus is an abnormal channel that forms between a periapical infection and the oral cavity, allowing pus to drain into the mouth. It is a common consequence of chronic odontogenic infections, typically resulting from untreated dental caries, pulpal necrosis, or failed endodontic treatment. The condition often presents as a small, erythematous nodule or an opening on the gingiva or alveolar mucosa, which may intermittently discharge purulent material. While patients may experience discomfort during the initial infection phase, pain often subsides once the sinus tract establishes drainage, leading to delayed diagnosis and persistent low-grade infection. The etiology of intraoral dental sinuses is primarily linked to periapical abscesses, which develop when bacterial infections from the root canal system extend into periapical tissues. The path of sinus tract formation is influenced by anatomical factors such as bone density and muscle attachments, determining whe ...

Dental Abscess
A dental abscess is a localized collection of pus associated with a tooth. The most common type of dental abscess is a periapical abscess, and the second most common is a periodontal abscess. In a periapical abscess, usually the origin is a bacterial infection that has accumulated in the soft, often dead, pulp of the tooth. This can be caused by tooth decay, broken teeth or extensive periodontal disease (or combinations of these factors). A failed root canal treatment may also create a similar abscess. A dental abscess is a type of odontogenic infection, although commonly the latter term is applied to an infection which has spread outside the local region around the causative tooth. Classification The main types of dental abscess are: * Periapical abscess: The result of a chronic, localized infection located at the tip, or apex, of the root of a tooth. * Periodontal abscess: begins in a periodontal pocket (see: periodontal abscess) * Gingival abscess: involving only ...

Odontogenic Infection
An odontogenic infection is an infection that originates within a tooth or in the closely surrounding tissues. The term is derived from '' odonto-'' (Ancient Greek: , – 'tooth') and '' -genic'' (Ancient Greek: , ; – 'birth'). The most common causes for odontogenic infection to be established are dental caries, deep fillings, failed root canal treatments, periodontal disease, and pericoronitis. Odontogenic infection starts as localised infection and may remain localised to the region where it started, or spread into adjacent or distant areas. It is estimated that 90–95% of all orofacial infections originate from the teeth or their supporting structures and are the most common infections in the oral and maxilofacial region. Odontogenic infections can be severe if not treated and are associated with mortality rate of 10 to 40%. Furthermore, about 70% of odontogenic infections occur as periapical inflammation, i.e. acute periapical periodontitis or a periapical abscess. The n ...

Osteomyelitis
Osteomyelitis (OM) is the infectious inflammation of bone marrow. Symptoms may include pain in a specific bone with overlying redness, fever, and weakness. The feet, spine, and hips are the most commonly involved bones in adults. The cause is usually a bacterial infection, but rarely can be a fungal infection. It may occur by spread from the blood or from surrounding tissue. Risks for developing osteomyelitis include diabetes, intravenous drug use, prior splenectomy, removal of the spleen, and trauma to the area. Diagnosis is typically suspected based on symptoms and basic laboratory tests as C-reactive protein and erythrocyte sedimentation rate. This is because plain radiographs are unremarkable in the first few days following acute infection. Diagnosis is further confirmed by blood tests, medical imaging, or bone biopsy. Treatment of bacterial osteomyelitis often involves both antimicrobials and surgery. Treatment outcomes of bacterial osteomyelitis are generally good when t ...

Gingival And Periodontal Pocket
In dental anatomy, the gingival and periodontal pockets (also informally referred to as gum pockets) are dental terms indicating the presence of an abnormal depth of the gingival sulcus near the point at which the gingival (gum) tissue contacts the tooth. Tooth gingival interface The interface between a tooth and the surrounding gingival tissue is a dynamic structure. The gingival tissue forms a crevice surrounding the tooth, similar to a miniature, fluid-filled moat, wherein food debris, endogenous and exogenous cells, and chemicals float. The depth of this crevice, known as a sulcus, is in a constant state of flux due to microbial invasion and subsequent immune response. Located at the depth of the sulcus is the epithelial attachment, consisting of approximately 1 mm of junctional epithelium and another 1 mm of gingival fiber attachment, comprising the 2 mm of biologic width naturally found in the oral cavity. The sulcus is literally the area of separation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pulp Necrosis
Pulp necrosis is a clinical diagnostic category indicating the death of cells and tissues in the pulp chamber of a tooth with or without bacterial invasion. It is often the result of many cases of dental trauma, caries and irreversible pulpitis. In the initial stage of the infection, the pulp chamber is partially necrosed for a period of time and if left untreated, the area of cell death expands until the entire pulp necroses. The most common clinical signs present in a tooth with a necrosed pulp would be a grey discoloration of the crown and/or periapical radiolucency. This altered translucency in the tooth is due to disruption and cutting off of the apical neurovascular blood supply. Sequelae of a necrotic pulp include acute apical periodontitis, dental abscess or radicular cyst and discolouration of the tooth. Tests for a necrotic pulp include: vitality testing using a thermal test or an electric pulp tester. Discolouration may be visually obvious, or more subtle. Treat ...

Root Canal Treatment
Root canal treatment (also known as endodontic therapy, endodontic treatment, or root canal therapy) is a treatment sequence for the infected pulp of a tooth that is intended to result in the elimination of infection and the protection of the decontaminated tooth from future microbial invasion. It is generally done when the cavity is too big for a normal filling. Root canals, and their associated pulp chamber, are the physical hollows within a tooth that are naturally inhabited by nerve tissue, blood vessels and other cellular entities. Endodontic therapy involves the removal of these structures, disinfection and the subsequent shaping, cleaning, and decontamination of the hollows with small files and irrigating solutions, and the obturation (filling) of the decontaminated canals. Filling of the cleaned and decontaminated canals is done with an inert filling such as gutta-percha and typically a zinc oxide eugenol-based cement. Epoxy resin is employed to bind gutta-percha i ...

Root Canal
A root canal is the naturally occurring anatomic space within the root of a tooth. It consists of the pulp chamber (within the coronal part of the tooth), the main canal(s), and more intricate anatomical branches that may connect the root canals to each other or to the surface of the root. Structure At the center of every tooth is a hollow area that houses soft tissues, such as the nerve, blood vessels, and connective tissue. This hollow area contains a relatively wide space in the coronal portion of the tooth called the pulp chamber. These canals run through the center of the roots, similar to the way graphite runs through a pencil. The pulp receives nutrition through the blood vessels, and sensory nerves carry signals back to the brain. A tooth can be relieved from pain if there is irreversible damage to the pulp, via root canal treatment. Root canal anatomy consists of the pulp chamber and root canals. Both contain the dental pulp. The smaller branches, referred to as '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
