Unlabelled: The aim of this study was to establish the mean distances between the maxillary sinus floor and the roots of the lateral maxillary teeth in dentate subjects, respectively the mean height of the available bone for oral implant placement in the corresponding area, in edentulous ones.
Material And Methods: We determined the maxillary sinus floor position in relation to morphoclinical alveolodental benchmarks on 50 dry skulls, dentate 30 and edentulous 20, and correlations were performed by use of 40 CT-scans of the targeted area. In addition, 20 human adult cadavers were bilaterally dissected in order to bring topographical evidence at that level.
Results: The data we obtained lead us to define three dentosinusal relations: tangent (close) relation 60.8%; distanced relation 25.6%; penetrating relation: 13.6%; three subantral classes in edentulous patients, emphasizing the direct relation of the age of the edentulism and the degree of bone resorption. We discuss the results we obtained from the viewpoint of their application in the field of oral implantology.
Conclusions: The maxillary sinus floor represents the danger zone for the oral implantology.

In the literature, there is divergence about the relationship between anatomical variations of the turbinates and nasal septum (NS) and alterations in the maxillary sinus (MS) mucosa. To determine, through cone-beam computed tomography (CBCT) images of Brazilian individuals, the prevalence and relationship of anatomical variations of the turbinates and NS with alterations in the mucosa of the MS, as well as to analyze the relationships of these variables with demographic data. The present cross-sectional study involved the analysis of 120 CBCT scans using the i-CAT Vision software, conducted by 2 calibrated examiners.

Isolated maxillary fungal pathologies involve a variety of clinical entities. These include invasive and non-invasive variants, where each has a unique pathogenesis, clinical manifestation, and approach for management. The aim of this case series is to investigate the several ways that fungal infections of the maxillary sinus might present, with the approach to diagnose and manage these conditions.

The outcome of tooth autotransplantation depends mainly on the transplant tooth's anatomy-the type of donor tooth and the developmental stage of root formation. Mature teeth display a higher complication rate due to lower pulp revascularization potential, requiring root canal treatment (RCT) pre- or postoperatively to avoid postoperative complications, which extends treatment duration and cost. This report details a 39-year-old patient's autotransplantation of a mature wisdom tooth to replace the first molar after unsuccessful root canal retreatment.

Fungal rhinosinusal infections comprise several nosological entities, including sinus fungus ball. Diagnosis of sinus fungus ball relies on patient interrogation and clinical and paraclinical findings. Mold species commonly involved include Aspergillus, as well as dematiaceous fungi.
