Expression of MMP-2 and MMP-9 in odontogenic myxoma in a child: report of a clinical case
2011
Odontogenic myxoma (OM) is a benign, locally invasive, non-metastasizing neoplasm of the jaw bones. Despite the benign nature of these lesions, there is a high rate of recurrence and the current recommended therapy, depending on the size and behaviour of the lesion, can vary from curettage with peripheral ostectomy, segmental resection up to radical resections for more aggressive lesions. OM is a rare tumour which occurs predominantly in the third decade of life and it is rare in children. Matrix metalloproteinases (MMPs) are a family of extracellular endopeptidases responsible for the degradation and remodelling of extracellular matrix, they are known to be involved in the progression and …
The recurrence of odontogenic keratocysts in pediatric patients is associated with clinical findings of Gorlin-Goltz Syndrome
2019
Background Odontogenic keratocyst (OKC) is an odontogenic developmental cyst that presents distinct clinical behavior. This lesion has been described as dental cysts with keratinization since the 1930s, however the term "OKC" was established in 1956. This study aims to determine the frequency and features of OKC in children aged 0 to 14 years in an oral pathology service in Brazil. Material and Methods A retrospective study was performed to review cases of OKC in children diagnosed between 1986 and 2017. Clinical data were evaluated from medical records (gender, race, age, anatomical location, treatment, radiographic findings and follow-up). Results Ninety-seven cases of OKC were diagnosed …
Retrospective analysis of Desmoplastic Ameloblastoma:clinical review
2020
Background Desmoplastic Ameloblastoma (DA) is a rare, true neoplasm of jaws with reported incidence of 4-13% among other variants of Ameloblastoma, however this appears distinct than the classic Ameloblastoma in anatomical distribution and clinical presentation. This is often mistaken as a fibro-osseous lesion because of its similar radiological appearance. Material and Methods To describe the clinical, radiographic and histopathological characteristics through a series of new cases of histologically proven DA including a case of an exceptionally large, recurrent lesion along with retrospective analysis of cases from literature available for an improved understanding of the behaviour and pr…
Bisphosphonate-related osteonecrosis of the jaws (Bronj).
2011
Bisphosphonate-related osteonecrosis of the jaws (BRONJ) is an extremely therapy resistant osteomyelitis-like disease exclusively involving the jaw bones of patients in treatment with bisphosphonates (BPs). Objectives: The aim of this study was to evaluate the radiological and clinical findings and management of 51 patients with BRONJ diagnosed from 2004 to 2009 in our Reference Center. Study Design: A prospective study was performed. The patients were examined every 2-6 months, depending on their clinical conditions. Outcome variables were the resolution of symptoms, persistence of bone exposure and / or fistula and the status of the lesional mucosa. Results: The higher prevalence of the d…
Effects of various hygiene procedures on the surface characteristics of titanium abutments.
1996
The use of cleaning instruments on titanium implants may cause undesired surface alterations. In a qualitative and quantitative assessment of these alterations, 5 titanium implant abutments were treated with a steel curet, a prototype pure titanium curet, an air abrasive polishing system, and an ultrasonic system. Custom-made polymer templates, used to secure the curet to a vertical guide bar and a spring scale to maintain a constant instrument pressure, guaranteed a standardized procedure and reproducible results. The ultrasonic and the air abrasive polishing method were also standardized. Evaluation by scanning electron microscopy (SEM) revealed surface alterations for all instruments and…
Effect of diode laser irradiation on the attachment rate of periodontal ligament cells: an in vitro study.
2001
The present study is part of a basic research program investigating the cellular effects of an 810 nm GaAlAs-diode laser on human periodontal tissues. The aim of the investigation was to evaluate the effects of laser treatment of root surface specimens on the attachment of periodontal ligament (PDL) cells in vitro.Root specimens were prepared from periodontally diseased teeth. PDL cells were obtained from human third molar ligaments. Cells were cultured under simple, standardized, and reproducible experimental conditions. One hundred fifty root specimens were scaled and root planed with curets followed by air-powder abrasive treatment; 75 were then lased and 75 served as controls. The irrad…
Replantation of a maxillary second molar after removal of a third molar with a dentigerous cyst: Case report and 12-month follow-up
2014
The aim of this study was to describe the replantation of a maxillary second right molar, which had been removed for surgical reasons in order to remove a dentigerous cyst associated with the adjacent third molar, and the case’s 12-month follow-up. A 51-year-old man presented swelling in the right maxillary area. Radiographic examination showed a large radiolucency in close proximity to the third molar, suggesting a follicular cyst. The third molar was extracted and the cyst underwent curettage. The second molar had to be extracted to enable complete removal of the cyst and to achieve primary closure of the wound, which would have been impossible without repositioning the molar. With this o…
Distal probing depth and attachment level of lower second molars following surgical extraction of lower third molars : a literature review
2009
A review of the literature is made to evaluate factors that influence probing depth and attachment level on the distal aspect of the lower second molar (L2M) following extraction of a lower third molar (L3M). The PubMed database was searched for studies published between 1997 and March 2009 using the following keywords: mandibular third molar, distal periodontal defect, distal probing depth, distal attachment level, flap design. Randomized prospective studies, with a minimum follow-up of three months for which the full text could be obtained, and that indicated the attachment level and/or probing depth on the distal surface of the L2M in both the preoperative and postoperative periods were …
Wertigkeit der Abradathistologie von Endometriumkarzinomen
2002
Objective: We compared immunohistological examination of endometrium biopsy specimen with the results of the immunohistological examination of tumor specimen to analyse the valence of this preoperative examination according to the clinico-pathological findings and overall-survival. Material and Method: Between 1985 and 1995 193 women were treated of an endometrial carcinoma at the University hospital Mainz. In this group we evaluated 41 patients with enough preoperative endometrial biopsy material for a retrospective immunohistochemical analysis and complete follow-up data. The materials from diagnostic curettage were stained and analysed for oestrogen and progesterone receptor status and f…
