Stafne's bone cavity: An unusual case with involvement of the buccal and lingual mandibular plates

Lingual mandibular bone defects, also known as Stafne bone cavity (SC), are unilateral asymptomatic radiolucencies, generally seen in the mandibular angle, below the inferior alveolar canal. Although panoramic radiographies normally offer enough information to make a correct diagnosis, additional studies are often required, especially in atypical cases. The present report describes an atypical presentation of a Stafne's bone cavity in a 78 years-old male patient. In this particular case, an asymptomatic and radiolucid lesion was observed during a routine dental examination. The computed tomography (CT) showed an involvement of both lingual and buccal mandibular plates producing a tunnel-like lesion. No history of mandibular trauma or surgery was refered. An additional magnetic resonance imaging (MRI) was made to discard submandibular gland pathology and to confirm the diagnosis. Since SC is asymptomatic and nonprogressive, a conservative approach based in clinical and radiological follow-ups was considered to be the most suitable treatment option

Retrospective study of the bone morphology in the posterior mandibular region. Evaluation of the prevalence and the degree of lingual concavity and their possible complications

In order to choose the appropriate implant size and to prevent complications, an oral surgeon must know the size and shape of the mandible. In the posterior mandibular region, a lingual undercut is often found and could represent a difficulty hard to manage if a lingual or buccal perforation occur. A large series of computed tomography (CT) images of the mandibular first molar was evaluated and the bone morphology, the prevalence and the degree of the lingual concavity in the first molar region were studied. One hundred and fifty-one computed tomography (CT) examinations of patients were retrospectively evaluated to determine anatomical variations in bone morphology in the submandibular fossa region. A total of 151 subjects were included, consisting of 64 males (M) (42.4%) and 87 females (F) (57.6%). The under-cut type ridge was present in 64.2% of the cases. The concavity angle was 66.6 ± 8.9° (M) and 71.6 ± 8.4° (F) and the linear concavity depth 4.5 ± 2.3 mm (M) and 3.1 ± 1.7 mm (F) (p>0.05). Mandibles with any lingual concavity present a potential increased risk of lingual cortical perforation during implant placement surgery. CT imaging allows characterizing the anatomy of the submandibular fossa and provides other important information for the preoperative assessment of the posterior mandible for dental implants placement

The use of low level laser therapy in the treatment of temporomandibular joint disorders: review of the literature

Introduction: The temporomandibular disorders (TMDs) have been identified as the most important cause of pain in the facial region. The low level laser therapy (LLLT) has demonstrated to have an analgesic, anti-inflammatory and biostimulating effects. The LLLT is a noninvasive, quick and safe, non-pharmaceutical intervention that may be beneficial for patients with TMDs. However the clinical efficiency of LLLT in the treatment of this kind of disorders is controversial. Objectives: Literature review in reference to the use of LLLT in the treatment of TMDs, considering the scientific evidence level of the published studies. Material and Methods: A MEDLINE and COCHRANE database search was made for articles. The keywords used were "temporomandibular disorders" and "low level laser therapy" or "phototherapy" and by means of the Boolean operator "AND". The search provided a bank of 35 articles, and 16 relevant articles were selected to this review. These articles were critically analyzed and classified according to their level of scientific evidence. This analysis produced 3 literature review articles and 13 are clinical trials. The SORT criteria (Strength of Recommendation Taxonomy) was used to classify the articles. Results: Only one article presented an evidence level 1, twelve presented an evidence level 2, and three presented an evidence level 3. According to the principle of evidence-based dentistry, currently there is a scientific evidence level B in favor of using LLLT for treatment of TMDs. Discussion and conclusions: Publications on the use of LLLT for treatment of TMDs are limited making difficult to compare the different studies due to the great variability of the studied variables and the selected laser parameters. The great majority of the studies concluded that the results should be taken with caution due to the methodological limitations

Revisión bibliográfica de implantología bucofacial del año 2011. Segunda parte

La gran diversidad de fuentes de información que nos proporciona la literatura científica junto al escaso tiempo de que disponen los profesionales de la Odontología para consultarlas, ha motivado a los autores a efectuar una revisión de la literatura científica publicada a lo largo del año 2011 en el campo de la Implantología Bucofacial. Con este fin se han agrupado los diferentes artículos indexados consultados en distintos apartados (elevación del seno maxilar, cirugía guiada y cirugía mínimamente invasiva, regeneración ósea guiada, implantes ci-gomáticos y factores de crecimiento), con el fin de facilitar una buena puesta al día

Rare and complex urology : clinical overview of ERN eUROGEN

Background: In 2017, the European Commission launched 24 European Reference Networks (ERNs). ERN eUROGEN is the network for urorectogenital diseases and complex conditions, and started with 29 full member healthcare providers (HCPs) in 11 countries. It then covered 19 different disease areas distributed over three work -streams (WSs). Objective: To provide an overview and identify challenges in data collection at European level of the ERN eUROGEN patient population treated by HCPs in the network. Design, setting, and participants: A retrospective cohort study was conducted of the 29 HCPs who were full members between 2013 and 2019. Outcome measurements and statistical analysis: Data were extracted from the original HCP applications and the ERN continuous monitoring system. Patient volumes, new patient numbers, and procedures were compared between different WSs, countries, and HCPs. Discrepancies between monitoring and application data were identified. Results and limitations: Between 2013 and 2019, 122 040 patients required long-term care within the 29 HCPs. The volume of patients treated and procedures undertaken per year increased over time. Large discrepancies were found between patient numbers contained in the application forms and those reported in the continuous monitoring system (0-1357% deviation). Conclusions: Patient numbers and procedures increased across ERN eUROGEN HCPs. Reliable data extraction appeared challenging, illustrated by the patient volume dis-crepancies between application forms and the continuous monitoring data. Improved disease definitions, re-evaluation of affiliated HCPs, and valid data extraction are needed for future improvements. Patient summary: We analysed the patient population with rare urorectogenital dis-eases or complex conditions within the ERN eUROGEN network between 2013 and 2019. Clinical activity was found to increase, but differences in patient numbers were evident between healthcare providers. In order to acquire valid patient numbers, both improved definitions of diagnostic codes and greater insight into the data-gathering process are required. (c) 2021 The Authors.
