Oral health effects of botulinum toxin treatment for drooling:a systematic review
2020
Background Drooling is a major morbidity in several neurological diseases. Intraglandular botulinum neurotoxin (BoNT) injections have been used to manage this condition. However, by decreasing salivary flow, BoNT injections may result in an increased risk of caries and other oral adverse effects. In this study, we aimed to assess whether, in patients with drooling, intraglandular BoNT injections are associated with increased dental caries development, modifications on salivary composition (oral pH, buffering capacity and osmolality) and cariogenic bacterial load. Material and Methods We performed a systematic review, searching PubMed, CENTRAL, Web of Science, and Scopus for all experimental…
Successful conservative treatment of a mandibular unicystic ameloblastoma : 13-year follow-up
2018
Ameloblastoma is an uncommon, locally aggressive benign odontogenic tumor and can reach considerable dimensions causing facial deformity and functional impairment. They are characterized by local aggressiveness. It is recommended that maxillary ameloblastomas be treated aggressively due to proximity of various vital structures. Conservative treatments such as marsupialization, enucleation and curettage while preserving bone integrity seem to be associated with a high rate of recurrence. Treatment evaluation of ameloblastomas is a complex issue, as ideally it should not be so destructive due to the benign nature of this lesion, but should be extensive enough to avoid recurrences. The present…
Unusual microscopic changes of Ameloblastic Fibroma and Ameloblastic Fibro-odontoma : a systematic review
2019
Background Ameloblastic fibroma (AF) and ameloblastic fibro-odontoma (AFO) are uncommon benign mixed odontogenic neoplasms. Although unusual microscopic changes including hybrid tumors have been documented in publications, their clinical outcome prediction and treatment modality selection are still challenging due to scarcity. Objective: Analysis of AF/AFO's unusual microscopic variants in order to improve histopathologic diagnosis and to help clinicians in making informed treatment choices. Material and methods An electronic search was performed in PubMed's database using keywords: "ameloblastic fibroma", "ameloblastic fibroodontoma", "ameloblastic fibro-odontoma". The search scheme was li…
Hybrid ameloblastoma and central giant cell lesion : challenge of early diagnosis
2020
Hybrid lesions encompass the occurrence of different entities in one lesion. A 67-year-old woman was referred to the Oral and Maxillofacial Surgery Service for treatment of mandibular Central Giant Cell Lesion (CGCL) previously diagnosed. Intraoral examination revealed edentulism and a painless swelling extending from the alveolar ridge to the buccal vestibule with hard consistency covered by normal mucosae, with unknown duration. Panoramic radiograph revealed a large, multilocular and well-defined radiolucent lesion extending from the region of left mandibular lateral incisor teeth to right mandibular first molar with no evidence of osseous perforation. Initially, a treatment with intrales…
Peripheral desmoplastic ameloblastoma: histopathological and immunohistochemical profile of a case.
2009
In this study we present a rare case of peripheral desmoplastic ameloblastoma and discuss its clinical features, histopathology, and inmunoshistochemical profile. This article reports a new case of this unusual neoplasm in a 66 year-old woman in which the main complaint was an asymptomatic swelling located in the right body of mandible. Histopathological findings were similar to the two previously reported cases of this tumor. Positive immunohistochemical stain for laminin V and type IV collagen suggests an inductive effect of the epithelium over the stroma while the low index of p53 protein and Ki-67 expression in epithelium and stromal cells, as well as CD138 uniform positive-stain in epi…
Role of radiology in central hemangioma of jaws
2010
Central hemangioma, a bone destructive lesion, is a benign tumor. Hemangiomas of jaws are rare entity and produ- ces many different radiographic images. Radiographic differential diagnosis includes osteosarcoma, fibrous dysplasia, central giant cell granuloma, ameloblastoma, odontogenic myxoma, multiple myeloma, dentigerous cyst and aneurysmal bone cyst. Since it involves proliferation of blood vessels so aspiration or biopsy of such lesions can lead to severe hemorrhage which can turn out to be lethal. We stress on the importance of radiology in the timely diagnosis of such lesions which can prevent the disaster not only to the patient but also to oral surgeon in legal and professional asp…
Unicystic ameloblastoma in 3 year old paediatric patient: a rare entity
2013
Unicystic ameloblastoma (UA) is a benign epithelial odontogenic tumor of the jaws that commonly occurs in 2nd and 3rd decade of life. In fact, this entity is rare in children under 12 years of age. It is characterised as a distinct variant of ameloblastoma, exhibiting a less aggressive behaviour and a lower rate of recurrence than solid conventional ameloblastoma. There are very few reported cases of UA occurring in children below five years of age. The purpose of this case report is to describe a case of UA involving the crown of an unerupted maxillary second premolar in a 3 year old girl. The pathogenesis, clinical appearance, radiographic presentation, histological findings and managemen…
Therapeutic management of the odontogenic keratocyst. An energetic approach with a conservative perspective and review of the current therapeutic opt…
2020
Background Odontogenic keratocysts (OKC) are cystic lesions appearing in the jaws, usually asymptomatic with a progressive growth into the bone. Many of them are diagnosed by a routine radiological examination. Material and methods This study reports a 12-year-old girl that presented an asymptomatic large radiolucent unilocular lesion associated to the crown of 3.8 that caused displacement of the molar and the inferior alveolar canal. Differential diagnosis included OKC, unicystic ameloblastoma, ameloblastic fibroma, dentigerous cyst and orthokeratinized odontogenic cyst. Two surgical interventions were performed; first, a marsupialization, and 10 months after, the third molar extraction pl…
Surgical management of ameloblastoma. Review of literature
2019
Background Ameloblastoma is an odontogenic tumor that represents 1% of all tumors in the oral cavity and it is clinically classified in three types. Currently, solid and multi-cystic are considered locally aggressive, with high recurrence rates with conservative treatment. Material and methods Objective of the present review is to assess whether the surgical treatment should be conservative or radical. English articles published between 2009-2014, with available summary and in humans were included. Results 241 articles were found, 188 were excluded because analyzing. 53 articles were analyzed and finally 14 were selected for this review. Conclusions The optimal surgical treatment of amelobl…
Non-endodontic periapical lesions clinically diagnosed as endodontic periapical lesions: A retrospective study over 15 years
2021
Background This study aimed to provide the frequency and demographic data of non-endodontic periapical lesions clinically misdiagnosed as endodontic periapical lesions from a Southeast Asian population over a 15-year period. Material and methods A retrospective study was conducted from departmental archives between 2005 and 2019. Cases clinically diagnosed as endodontic periapical lesions were retrieved. Then, cases with a histopathological diagnosis of non-endodontic periapical lesion were selected. Demographic data of non-endodontic periapical lesions were recorded. Radiographic features of cases with available radiographs were analyzed. Results Of 1,566 cases clinically diagnosed as endo…
