This paper describes a quantitative analysis of the cyst lining architecture in radicular cysts (of inflammatory aetiology) and odontogenic keratocysts (thought to be developmental or neoplastic) including its 2 counterparts: solitary and associated with the Basal Cell Naevus Syndrome (BCNS). Epithelial linings from 150 images (from 9 radicular cysts, 13 solitary keratocysts and 8 BCNS keratocysts) were segmented into theoretical cells using a semi-automated partition based on the intensity of the haematoxylin stain which defined exclusive areas relative to each detected nucleus. Various morphometrical parameters were extracted from these cells and epithelial layer membership was computed using a systematic clustering routine. Statistically significant differences were observed across the 3 cyst types both at the morphological and architectural levels of the lining. Case-wise discrimination between radicular cysts and keratocyst was highly accurate (with an error of just 3.3%). However, the
The periapical cyst (also termed radicular cyst or inflammatory cyst) is the most common odontogenic cyst. Periapical is defined as "the tissues surrounding the apex of the root of a tooth" and a cyst is "a pathological cavity lined by epithelium, having fluid or gaseous content that is not created by the accumulation of pus." Most frequently located in the maxillary anterior region, it is caused by pulpal necrosis secondary to dental caries or trauma. The cyst has lining that is derived from the epithelial cell rests of Malassez which proliferate to form the cyst. Highly common in the oral cavity, the periapical cyst is asymptomatic, but highly significant because a secondary infection can cause pain and damage. In radiographs, it appears a radiolucency (dark area) around the apex of a tooths root. Periapical cysts comprise approximately 75% of the types of cysts found in the oral region. The ratio of individuals diagnosed with periapical cysts is 3:2 male to female, as well as individuals ...

Radicular pain is one disease that affects individuals of productive age between 20-60 years old. It can decrease one’s quality of life or work productivity.Dr. Agus Yunianto, Sp.BS., said Hernia Nucleus Pulposus Lumbalis (HNPL) was a pain disease of the back often experienced by humans. It happened due to the protusion of discus intervertebra lumbalis that suppresses nerve roots, causing pain.“Radicular pain will heal spontaneously or with a therapy,” he said on Wednesday during doctoral promotion (23/3) at Faculty of Medicine UGM.The coordinator of nerve surgery unit at RSPAD Gatot Soebroto Hospital said only 10 percent of radicular pain need surgery. Therapy for HNPL is currenlty limited to remove the nucleus protruding.“Despite the surgery to remove the discus protruding and release nerve roots, many patients complain of pain in the two year’s follow-up,” he said.His research on 33 patients of HNPL at RSPAD Gatot Soebroto Hospital showed that the pain was not

Background: Dentigerous cyst is although not uncommon but now is infrequently found in otolaryngological practice after the development of dental fraternity. Many times, they are encountered because of swelling in head neck area and facial disfigurement. NCCT and OPG play important role in its diagnosis. Removal can be both open or endoscopically. Methods: This prospective study was carried on n= 5 patients suspected of Dentigerous Cyst were included in our study on the basis of inclusion and exclusion criteria. Results: Here a series of five cases of Dentigerous cyst is presented with discussion regarding clinical and radiological features and treatment with a short review of literature. Conclusions: The Dentigerous cyst are usually encountered in ENT OPD and needs to be properly investigated. Advent of endoscopes and knowledge of anatomy of the area gives edge to the Otorhinolaryngologist over dentist in its management. ...
The globulomaxillary cyst is a cyst that appears between a maxillary lateral incisor and the adjacent canine. It exhibits as an "inverted pear-shaped radiolucency" on radiographs, or X-ray films. The globulomaxillary cyst often causes the roots of adjacent teeth to diverge. This cyst should not be confused with a nasopalatine cyst. The developmental origin has been disputed. Today, most literature agree based on overwhelming evidence that the cyst is predominantly of tooth origin (odontogenic), demonstrating findings consistent with periapical cysts, odontogenic keratocysts or lateral periodontal cysts.

TY - JOUR. T1 - Alternative Adhesive Strategies to Optimize Bonding to Radicular Dentin. AU - Bouillaguet, Serge. AU - Bertossa, Bruno. AU - Krejci, Ivo. AU - Wataha, John C.. AU - Tay, Franklin R.. AU - Pashley, David H.. PY - 2007/10/1. Y1 - 2007/10/1. N2 - This study tested the hypothesis that bond strengths of filling materials to radicular dentin might be optimized by using an indirect dentin bonding procedure with an acrylic core material. Roots of human teeth were endodontically prepared and obturated with EndoREZ, Epiphany, or the bonding of an acrylic point with SE Bond by using a direct or an indirect bonding technique. Bond strengths of endodontic sealers to radicular dentin were measured with a thin slice push-out test. Push-out strengths of EndoREZ and Epiphany to radicular dentin were less than 5 megapascals (MPa). The direct bonding technique with acrylic points and the self-etching adhesive had push-out strengths of 10 MPa, increasing to 18 MPa with the indirect technique. The ...

A cyst (fluid filled cavity) of the pancreas may be either inflammatory caused by pancreatitis, or neoplastic (a tumor).. Pseudocyst: Inflammatory cysts of the pancreas are called pseudocysts because they do not have a true cyst lining. These fluid filled structures within or around the pancreas are the result of severe pancreatitis that resulted in a disruption of the pancreatic ductal system and leakage of pancreatic fluid. Over a period of several weeks, the body encapsulates the fluid within a dense fibrous capsule creating the pseudocyst. Pseudocysts are not tumors and they do not have the potential to become cancer. Many of these cyst swill resolve with time, however, some will continue to enlarge and may be symptomatic. Persistent and symptomatic pseudocysts will require a drainage procedure. This was traditionally accomplished surgically by performing a cystgastrostomy, but most patients can now undergo an endoscopic cystgastrostomy and avoid surgery altogether.. Cystic neoplasms or ...

Objective: In jawbones, ameloblastomas and odontogenic keratocysts share many clinical features in common such as aggressiveness, high recurrence rates and radical management options. Understanding the pathogenesis and biological aspects of these tumors would improve the success of diagnose and treatment procedures. The aim of this study was to exhibit the reasons of high recurrence rates and growth potentials of ameloblastomas and keratocystic odontogenic tumours by investigating the expression of IL-1? and IL-6 and IL-1? -889 gene polymorphism. IL-1? and IL-6 are shown as very effective tissue degrading factors in bone remodelling. Study Design: This study included 25 cases of ameloblastomas, 41 cases of keratocystic odontogenic tumors (parakeratinized odontogenic keratocysts) and 8 cases of orthokeratinized odontogenic keratocysts. All histological slides were stained immunohistochemically to show the expression of IL-1? and IL-6. Restriction fragment length analysis was used to investigate ...
TY - JOUR. T1 - Unerupted teeth associated with dentigerous cysts and treated with coronectomy. T2 - Mini case series. AU - Patel, Vinod. AU - Sproat, Chris. AU - Samani, Meera. AU - Kwok, Jerry. AU - McGurk, Mark. PY - 2013/10. Y1 - 2013/10. N2 - There is a resurgence of interest in coronectomy, but its appropriate application in the management of third molar teeth has yet to be defined. Dentigerous cysts associated with unerupted teeth are most commonly associated with mandibular third molars. In this case series we evaluate outcome after coronectomy of teeth with associated dentigerous cysts in cases where the inferior dental nerve was thought to be at risk, or there was an increased risk of mandibular fracture. We retrospectively studied 21 consecutive patients treated by coronectomy for dentigerous cysts at the Oral Surgery Department at Guys Hospital. The most commonly affected teeth were mandibular third molars (20/21). One patient had permanent injury to the inferior dental nerve, but ...

The present study showed a statistically significant correlation between regional thermal deficit values of the affected lower extremity and radicular pain intensity. Our results are in accordance with the results obtained by other authors, who have observed a correlation between temperature asymmetry and radicular pain, and show that IRT can be effective in the objective differentiation of the presence or absence of pain.5 7 9 10 In the present study, analysis of the correlation between the stated parameters demonstrated that the values of thermal deficit increase along with increased pain intensity (Fig 1). On the basis of this finding, it can be concluded that thermograms provide not only information about the existence of pain but also about pain intensity. This correlation has been explained as nociceptor excitation, the secondary consequence of which is vasoconstriction.26 A positive correlation between pain intensity and temperature asymmetry of the affected lower extremity was also found ...
Background: Dentigerous cyst is the most common type of developmental odontogenic cyst which originates from REE. It has the capacity for transformation to ameloblastoma, mucoepidermoid carcinoma and squamous cell carcinoma. ki-67 and PCNA are two cell proliferation markers which can be both detected in cysts and tumors of epithelial origin. ...
Answer: Dentigerous cyst. Histology: The cystic lumen is lined by a thin layer of epithelium ranging from 3 to 6 cell layers in thickness. In areas the dentigerous cyst lining may resemble reduced enamel epithelium although in most areas the lining itself tends to be composed of flattened to slightly cuboidal cellular elements. Mucous cells may be encountered along the epithelial lining although they are widely spaced and oftentimes difficult to demonstrate. Dystrophic mineralization of epithelial cells may sometimes be noted along the inner aspect of the cyst. Many dentigerous cysts demonstrate inflammation within the cyst wall leading to proliferation of the epithelial lining into a more stratified squamous type lining with formation of epithelial ridges or rete pegs.The subjacent connective tissue is fibrous to fibromyxomatous in nature with the latter finding often suggesting or being misdiagnosed as an odontogenic myxoma. Epithelial odontogenic rests which often appear inactive tend to be ...

The purpose of this study was to compare the first file that fits to the apex (FFFA) in each canal before and after early flaring to analyze if the size of file to fit to the apex would increase after flaring. One hundred mesial canals of lower first and second molars with complete apical formation and patent foramens were selected. The samples were randomly divided into two groups of 50 canals each. A file was fit to the apex in each canal and that size recorded. Radicular flaring was completed using Gates-Glidden drills in group 1 and Rapid Body Shapers in group 2. After flaring a file was again fit to the apex in the same manner as before and its size recorded. The mean diameter of FFFA before flaring (file diameters in mm x 10(-2)) was 14.46 (+/-4.12) and after 23.3 (+/-7.2) for group 1 (p | 0.001), whereas in group 2 the mean diameter of FFFA was 17.2 (+/-4.96) before and 25.6 (+/-6.36) after (p | 0.001). A Wilcoxon t test indicates a significant difference (p | 0.001) between the diameter of FFFA
