Aim: The aim of this study is to review the literature concerning malignant transformation of radicular cyst. Material and Method: A literature search using MEDLINE, accessed via the National Library of Medicine PubMed interface (http://www.ncbi.nlm.nih.gov/pubmed), searching for articles relating to the malignant transformation of radicular/residual cyst written in English from 1960-2013. Resu...

background periapical lesions are induced in response to injuries to periapical tissues, which are generally the result of infections within the root canal. mast cells actively participate to the inflammatory infiltration of periapical granulomas and cysts. objectives the aim of this study was to detect and compare the presence of mast cells in inflammatory periapical lesions, including cysts a...

Radicular cysts arise from non-vital teeth. They are inflammatory in nature and are the most common cystic lesion found in the jaw. We present a case of a massive maxillary radicular cyst in a 20 year-old man, diagnosed following an alleged assault and facial fracture. Subsequent abscess formation was initially thought to be infection secondary to haematoma due to fracture, but further investig...

PURPOSE To detect predominant bacteria associated with radicular cysts and discuss in light of the literature. MATERIAL AND METHODS Clinical materials were obtained from 35 radicular cysts by aspiration. Cultures were made from clinical materials by modern laboratory techniques, they underwent microbiologic analysis. RESULTS The following are microorganisms isolated from cultures: Streptoco...

OBJECTIVE The aim of the study was to determine the apoptotic features and proliferation potential of odontogenic keratocysts compared with ameloblastomas and radicular cysts by analysing the role of bax, bcl-2, and Ki-67. MATERIAL AND METHOD The study material consisted of 20 odontogenic keratocysts, 20 radicular cysts, and 20 ameloblastomas. Immunohistochemically, bax, bcl-2 and Ki-67 were ...

Odontogenic cysts are the most commonly occurring cysts in the jaws and are the reason for the radiolucent appearances. The radicular cyst is a type of an infl ammatory cyst, caused due to pulpal necrosis followed by trauma or caries, with an associated infl ammatory response at the periapical region. Many a times it is diffi cult to diff erentiate from other bony lesions and it poses diagnosti...

During the past few decades several authors have perpetuated the notion that nearly half of all periapical lesions are radicular cysts. A few studies, based on meticulous serial sectioning of periapical lesions retrieved in toto, have shown that the actual incidence of radicular cyst is only about 15% of all periapical lesions. Equally significant was the discovery in 1980 and recent confirmati...

AIM Though odontogenic lesions have in common origin from the primitive odontogenic epithelium , there is a diversity in their initiation behavior and growth. The aggressive nature of odontogenic keratocyst similar to ameloblastoma in comparision with the other common odontogenic (dentigerous and radicular) cyst could be due to possible differences in their epithelial linings. PCNA (Proliferati...
