The central odontogenic fibroma: How difficult can be making a preliminary diagnosis
2016
Central odontogenic fibroma (COF) is a rare benign odontogenic tumor derived from the dental ectomesenchymal tissues. A 16-year-old Caucasian female patient was referred by her dentist for a radiolucent asymptomatic area associated with the crown of the impacted lower right third molar. A preliminary diagnosis of a follicular cyst was supposed. The lesion was surgically removed under general anesthesia together with the impacted tooth. The microscopic diagnosis of the excised tissue revealed an odontogenic fibroma. No clinical or radiographic signs of recurrence were found five years after surgical excision. Despite the various differential diagnoses of homogeneous unilocular and well delim…
Simple bone cyst : description of 60 cases seen at a Brazilian School of Dentistry and review of international literature
2020
Background The aim of this study was to describe the relative frequency and the main demographic and clinic-radiographic features related to patients diagnosed with Simple bone cyst (SBC) in an Oral Diagnosis Service in Southeast Brazil and present a review and discussion of international literature on this topic. Material and Methods SBC cases from our service encompassing the period between 1978 and 2017 were selected. In addition, a literature search was performed in the Pubmed/MEDLINE online electronic database published between 1951 and 2019. Results A total of 2,459 cystic lesions were documented in our service, thus 60 patients were diagnosed with the SBC representing 2.4% of all jaw…
Odontogenic fibroma — a case report
2014
Abstract IThe present study outlines the case of a 30-year-old patient with central odontogenic fibroma. The tumour developed in the alveolar process of the maxilla in the area of 13–15. The study describes the clinical symptoms, the radiological image, treatment method and histopathological image of the tumour. The study also presents a one-year period of post-surgical observation.
Buccal fat pad excision for cheek refinement: A systematic review
2021
Background Buccal Fat Pad (BFP) excision has become an aesthetic surgical procedure. Although this procedure is quite common, it is important to bear in mind that the scientific evidence supporting the efficacy of this treatment is scarce and of low quality. The purpose of this systematic review was to analyse all relevant data to assess the efficacy and safety of BFP excision for improving midface aesthetics. Material and Methods A thorough search of MEDLINE (PubMed), Scopus and Cochrane Library databases was conducted. The PICO approach was used where healthy patients seeking cheek slimming and facial silhouette refining undergo BFP excision and were compared before and after surgery in t…
Does anti-inflammatory drugs modify the severe odontogenic infection prognosis? A 10-year’s experience
2020
Background Numerous biochemical datas support the noxious role of anti-inflammatory drugs on immune response. Those observations are often put forward for unfavorable evolution of odontogenic infection but has never been really proven in clinic. The aim of this study is to try to clarify this role based on the collection of the clinical course of odontogenic infections over a 10-year analysis period. Material and Methods The investigators implemented a prospective observational study. The sample was composed of patients managed between January 2004 and December 2014 for severe odontogenic infection based on three criteria: hospital admission, intravenous antibiotic therapy, tooth extraction…
Marsupialization of a large dentigerous cyst in the mandible with orthodontic extrusion of three impacted teeth. A case report
2017
The dentigerous cyst (DC) is the most common type of developmental odontogenic cyst. It is usually asymptomatic and associated with the crown of an unerupted or impacted tooth. However, after a long duration, it is likely to cause significant bone resorption, cortical expansion, and tooth displacement. This report presents a large infected DC in the mandible of a 12-year-old female patient. The DC was located inferior to badly decayed primary molars and surrounded three impacted permanent teeth: canine, first premolar, which had a dilacerated root, and second premolar. The DC was treated successfully by marsupialization and extrusion of the impacted teeth. In conclusion, the combination of …
Reduction rate by decompression as a treatment of odontogenic cysts
2017
Background: Odontogenic cysts are defined as those cysts that arise from odontogenic epithelium and occur in the tooth-bearing regions of the jaws. Cystectomy, marsupialization or decompression of odontogenic cyst are treatment approach to this pathology. The aim of this study was to evaluate the effectiveness of the decompression as the primary treatment of the cystic lesions of the jaws and them reduction rates involving different factors. Material and Methods: 23 patients with odontogenic cysts of the jaws, previously diagnosed by anatomical histopathology (follicular cysts (7) and radicular cysts (16)) underwent decompression as an initial treatment. Clinical examination and pre and pos…
Decompression induces inflammation but do not modify cell proliferation and apoptosis in odontogenic keratocyst
2022
Background Odontogenic keratocyst (OKC) is a development cyst, of odontogenic origin, that differs from other entities by its infiltrating and aggressive biological behavior. Among conservative treatments for large lesions, surgical decompression stands out, with a variable recurrence rate. Aim: To evaluate the histological effects of decompression treatment on OKC, including cell proliferation and apoptosis of epithelial cyst. Material and Methods 21 OKC cases were included. Samples were taken before and after surgical decompression for histological evaluation and immunohistochemical staining of Ki-67, MCM4/7, Bax and Bcl2. Data were analyzed and compared using Student’s t and Wilcoxon tes…
Evaluation of the osteoclastogenic process associated with RANK / RANK-L / OPG in odontogenic myxomas
2018
Background Odontogenic myxoma (OM) is a benign intraosseous neoplasm that exhibits local aggressiveness and high recurrence rates. Osteoclastogenesis is an important phenomenon in the tumor growth of maxillary neoplasms. RANK (Receptor Activator of Nuclear Factor κappa B) is the signaling receptor of RANK-L (Receptor activator of nuclear factor kappa-Β ligand) that activates the osteoclasts. OPG (osteoprotegerin) is a decoy receptor for RANK-L that inhibits pro-osteoclastogenesis. The RANK / RANKL / OPG system participates in the regulation of osteolytic activity under normal conditions, and its alteration has been associated with greater bone destruction, and also with tumor growth. Object…
Glandular odontogenic cyst: report of a new case with cytokeratin-19 expression
2013
The glandular odontogenic cyst (GOC) was a rare jawbone cyst described in 1988 by Gardner et al.1 as a distinct entity. This lesion can involve either jaw, but the anterior region of the mandible was the most commonly affected area. Clinical and radiographic findings were not specific, and the diagnosis of GOC can be extremely difficult due to the rarity of this lesion. The cyst presented a wall constituted by fibrous connective tissue and was lined by a non-keratinized stratified squamous epithelium of variable thickness. Large areas of the lining epithelium presented cylinder cells, sometimes ciliated. A variable amount of mucina was occasionally noted. Due to the strong similarities, thi…
