The inflammation usually follows the death of dental pulp. This paper presents a case report of a patient with radicular cyst . A radicular cyst developed - the dark spot in the x-ray. This inflammational stimulus gave the growth stimulus to the embryonic epithelial remains of the dental lamina. rests of malassez. Radicular cyst is the most common odontogenic cystic lesion of inflammatory origin. An early small lateral radicular cyst is restricted to a small area of the interradicular bone adjacent to the root surface. They may occur when an accessory canal opens to the lateral root surface of the non vital tooth. most common cyst of the jaw. Relating to a radicle.

Surgical management of radicular cyst followed by root canal treatment is presented, in this case report, of inflammatory origin arises from epithelial rests of malassez in periodontal ligament due to inflammation of the dental pulp. The amount of apolipoprotein B (apo B) was measured using slit-immunoblotting in 20 specimens of radicular cyst fluids. Most frequently located in the maxillary anterior region, the cyst is caused by pulpal necrosis secondary to dental caries or trauma. The 2023 edition of ICD-10-CM K04.8 became effective on October 1, 2022. Radicular cyst is formed by the stimulation and proliferation of an epithelial residues cell or rest of Malassez in the periodontal ligament. What is radicular cyst? Cyst is defined as a cavity layered by epithelium that contains liquid, semi-solid, or gaseous contents. Occur . A jaw cyst that originates from a periodontal ligament and is caused due to inflammation is called a radicular cyst. It is also known as periapical cyst, apical periodontal cyst, root end cyst, or dental cyst. It is a true cyst as the lesion consists of a pathologic cavity lined by epithelium and is often fluid.

In this article, a case of rare occurrence of dentigerous cyst in a 10-year-old child and its treatment are presented. A Radicular Cyst presupposes physical, chemical or bacterial injury resulting in death of pulp followed by stimulation of epithelial cell rests of malaseez which are present normally in periodontal ligament. rests of serres. Most radicular cysts appear as round- or pear-shaped, unilocular, lucent lesions in the periapical region 3. Odontogenic cysts in the maxilla originate from the epithelial remain associated with odontogenesis [ 1 ]. 68% of the cases of jaw cysts are relevant to the mandible. Odontogenic cyst are a group of jaw cysts that are formed from tissues involved in odontogenesis (tooth development). Radicular cyst is a pathologic cavity partially or completely lined by epithelium in an area of apical periodontitis that is the result of root canal infection of a tooth. .

Glandular odontogenic cysts (GOC) are developmental odontogenic cysts with glandular differentiation of the epithelium. The source of epithelium is cell rests of malassez and the proliferation is stimulated by inflammation. It arises from epithelial residues in the periodontal ligament as a result of inflammation. Radicular cysts are inflammatory odontogenic cyst, which typically presents as small radiolucent lesion around root apex of one or more teeth. Lateral periodontal cysts are defined as nonkeratinized and noninflammatory developmental cysts located adjacent or lateral to the root of a vital tooth. The most common factor considered to cause a radicular cyst is caries. The air-filled sinus and its thin walls provide less resistance to cyst growth, allowing it to considerably increase in size before they become symptomatic and are clinically noted.
