Effect of resin-modified glass-ionomer cement lining and composite layering technique on the adhesive interface of lateral wall

Interface integrity can be maintained by setting the composite in a layering technique and using liners. Objective The aim of this in vitro study was to verify the effect of resin-modified glass-ionomer cement (RMGIC) lining and composite layering technique on the bond strength of the dentin/resin adhesive interface of lateral walls of occlusal restorations. Material and Methods Occlusal cavities were prepared in 52 extracted sound human molars, randomly assigned into 4 groups: Group 2H (control) – no lining + two horizontal layers; Group 4O: no lining + four oblique layers; Group V-2H: RMGIC lining (Vitrebond) + two horizontal layers; and Group V-4O: RMGIC lining (Vitrebond) + four oblique layers. Resin composite (Filtek Z250, 3M ESPE) was placed after application of an adhesive system (Adper™ Single Bond 2, 3M ESPE) dyed with a fluorescent reagent (Rhodamine B) to allow confocal microscopy analysis. The teeth were stored in deionized water at 37oC for 24 hours before being sectioned into 0.8 mm slices. One slice of each tooth was randomly selected for Confocal Laser Scanning Microscopy (CLSM) analysis. The other slices were sectioned into 0.8 mm x 0.8 mm sticks to microtensile bond strength test (MPa). Data were analyzed by two-way ANOVA and Fisher's test. Results There was no statistical difference on bond strength among groups (p>;0.05). CLSM analysis showed no significant statistical difference regarding the presence of gap at the interface dentin/resin among groups. Conclusions RMGIC lining and composite layering techniques showed no effect on the microtensile bond strength and gap formation at the adhesive interface of lateral walls of high C-factor occlusal restorations

Rhinoscleroma causing severe bilateral nasal obstruction

AbstractRhinoscleroma is a chronic, infectious and granulomatous disease of the respiratory tract. There is often a delay in diagnosis due to unfamiliarity with the disease and also because culture is not always positive. We report a case in a 26-year-old woman with granular mass obstructing bilateral nasal cavities and causing breathing difficulty. Histopathological examination showed characteristic Mikulicz histiocytes containing numerous Gram-negative intracellular rod-shaped bacilli consistent with the diagnosis of rhinoscleroma. The patient was treated with gemifloxacin and tetracycline and remains asymptomatic over a year follow-up period. It is important to consider rhinoscleroma in cases of chronic nasal obstruction. As culture is not always positive, histopathological examination may be crucial to the diagnosis

Nasal Transmissible Venereal Tumor (TVT) with Bone Metastasis in a Dog

Background: Transmissible venereal tumor (TVT) is a highly contagious round cell neoplasm that affects dogs, and it is usually transmitted through coitus. The tumor is mainly located in the genital area; however, the neoplasm can also be extragenital, affecting the nose, mouth, and eyes, as well as the skin and superficial lymph nodes. Cytological examination is the most commonly used method for definitive diagnosis due to its low cost and fast execution. Chemotherapy, radiotherapy, surgical resection, and other procedures such as cryosurgery are the possible treatment options. The objective of this report was to describe a case of extragenital TVT with nasal primary site and metastasis in the bone tissue in a dog treated at a private veterinary hospital in the city of Belém, Pará, Brazil.Case: A 6-year-old male domiciliary Labrador Retriever dog, weighing 24.2 kg, received oncologic treatment in a private veterinary hospital in the city of Belém, Pará, Brazil. The animal had a history of neoplastic disease, and he had undergone TVT resection associated with chemotherapy treatment more than 3 years ago. The clinical examination revealed a volume increase in the periorbital region, left lateral ocular displacement, left nostril excessive epistaxis, recurrent sneezing, cough, and pain signs, and tumor metastasis was suspected. Complementary exams of oncological cytology, computed tomography (CT), hemogram, and serum biochemistry were requested for diagnosis and staging of the condition, and supportive therapy was prescribed. The cytological report showed a dense population of neoplastic round cells with characteristics of TVT. CT indicated the presence of a heterogeneous hypodense mass with irregular contours and partially defined limits, with slight uptake of the intravenously injected contrast medium that obliterated the nasal cavity, maxillary recess, nasopharyngeal meatus, frontal sinus, and sphenoid sinus on the left side. The hematological analysis revealed mild anemia, neutrophilia, and lymphopenia, while the biochemical analysis only showed hypocalcemia. The prescribed therapy was amoxicillin + potassium clavulanate, omega-3, firocoxib, tranexamic acid, and finally chemotherapy with lomustine. Since the patient did not return for follow-up, the outcome could not be determined.Discussion: The patient described in this report was a domiciliary dog who did not live with other pets, but had access to the community environment and contact with other animals. The animal’s history, clinical signs, and cytological and imaging findings were consistent with those of TVT. In extragenital presentations of TVT, the inguinal and sublumbar lymph nodes, lungs, and abdominal organs are most commonly affected. Furthermore, bone involvement is rare, as this has not been commonly described in the literature as compared to the other sites of metastases. An abrasive brush was used for the cytological sample collection, because it provides slides with richer cells as compared to the imprint samples. CT is an important tool for the diagnosis of neoformations in the skeleton, and this method demonstrated high efficiency in identifying the bone involvement and the degree of the invasion and lesion in this case. The therapeutic agents used in this case were different from the usual, since the patient was given lomustine (40 mg/capsule, orally) in the metronomic chemotherapy. This drug has been previously used as an alternative in a canine TVT case resistant to vincristine.Keywords: neoplasm, extragenital, computed tomography, TVT.Título: Tumor Venéreo Transmissível (TVT) nasal com metástase óssea em um cãoDescritores: neoplasia, extragenital, tomografia computadorizada, TVT
