Análise clínica, tomográfica e histológica comparativa entre ha+β-tcp isolado ou associado a proteínas derivadas do esmalte utilizadas como enxertos após a elevação da membrana do seio maxilar e colocação de implantes: estudo piloto

The aim of this study was to evaluate the clinical, tomographic, and histological similarity within the use of HA+β-TCP (Boneceramic) alone or associated with enamel matrix derived (EMD) proteins in sinus lifting procedures with subsequent dental implant placement. We selected two patients with residual bony ridges between 3 mm and 5 mm in height in need of bone grafts. Six months later, eight implants were installed (two implants at each site). Biopsies were made, and the tissue was processed and stained with HE solution. Tomographic evaluation showed bone height gain up to 10.0 mm on average. Histology showed new bone formation for both groups, with similar bone density and trabecular interconnectivity. It can be concluded that the HA+β-TCP graft isolated or associated to EMD provided bone height gain in sinus lifting procedures, with similar clinical, tomographic and histological characteristics.

Gengivite Plasmocitária induzida por uso de pimenta

The aim of this case report is present a case in which the patient had plasma cell gingivitis induced by consumption of pepper. Patient A.M.S., male, 23 years, presented himself at the Clinic of Periodontology, complaining of severe pain, bleeding gums and tooth mobility. Interview was conducted not observing anything relevant. In oral evaluation, we observed in the anterior swollen gums, bleeding, suppuration and great touch, and tooth mobility. Being an aggressive framework in relation to patient age, we performed the following laboratory tests: complete blood count, blood sugar, and coagulation, and biopsy in the anterior inferior, because a diagnosis of lymphoma. At the end of antibiotic therapy, a significant improvement of clinical symptoms, pain relief, less swollen gums and reduce the suppuration and mobility. Laboratory tests showed no change. Fifteen days later, the patient returned with worsening of clinical status. The pathological diagnosis was plasma cell gingivitis and then performed a new history by placing greater emphasis on dietary habits, and the patient reported consumption of pepper in their meals, and relate this to clinical presentation. After elimination of pepper diet the patient showed remission of clinical data.

Influência da agulha irrigadora e da dilatação do canal radicular na eficácia da irrigação endodôntica

Introduction: The irrigation of root canals aims to their cleaning and disinfection, improving endodontic treatment success. Objective: To investigate the influence of the diameter and type of irrigation needle and the root canal enlargement on the mechanical efficacy of endodontic irrigation. Material and methods: Twelve human single-rooted mandibular incisors were used. During some instrumentation stages (enlargement by #20, #30, and #40 K file), root canals were filled with radiographic contrast solution mixed to propyleneglycol and zinc oxide. Needles with different diameters and designs were employed: G1 – 23G and lateral opening; G2 – 22G and apical opening; G3 – 30G and lateral opening; G4 – 30G and apical opening. The needles were inserted up to resistance, with 1 mm step-back to avoid root canal obliteration. The irrigation was performed with 2 mL of distilled water. Before and after irrigation/aspiration, teeth were radiographed at bucco-lingual and mesiodistal direction, using a digital radiographic system. Then, root canal areas, before (filled by contrast solution) and after irrigation (remnant of contrast solution), were submitted to image subtraction with Adobe Photoshop CS4 software. Subsequently, the areas were measured by Image Tool 3.0 software, allowing the obtaining of the cleaning percentage for each modality. Data were analysed by using Anova and Tukey’s test. The level of significance was set at P < 0.05. Results: For all root canal enlargements, 30G needles (G3 e G4) presented a better cleaning efficacy. In all groups, higher cleaning efficacy percentage was observed at #30 and #40 K file enlargement. Conclusion: Regardless their design, thinner needles were more effective; a better cleaning efficacy occurred in more enlarged root canals.

Reabilitação estético-funcional sobre implantes agulhados e endósseos

This report shows the resolution of a case study whose aim was promote the aesthetic and functional rehabilitation of upper left hemi-arch over endosseous and needle implant prostheses. To improve the position of the needle implants, we performed the bucco-palatal bending of needles splinting them with composite resin; we removed the screwed implant prosthesis in the regions of the premolars (24 and 25) and molar (26). The mini-abutments of the last two implants were replaced, and in the first premolar and canine, we used cemented abutments due to implant angulation having planned soldering because of implant size and contact with one needle implant that could interfere with intimate contact bone/implant damaging biomechanics. Pick-up impressions were performed with an open tray, using a retractor cord in the needle implants and respective transfer copings. Therefore, models were related on semi-adjustable articulator after a face-bow recording and interocclusal indexes. After working cast fabrication and try-in of infra-structures, these were adjusted and related into the articulator again. Then, after ceramic build-up, adjustments, finishing, and torque, chemically-activated resin cement was applied on units 21 to 24. At the end of the case, we concluded that a good aesthetic and functional rehabilitation depends on thorough knowledge of techniques for each clinical situation.

Revisão sistemática: hiperplasia fibroadenomatosa mamária felina

A hiperplasia fibroadenomatosa mamária felina é uma enfermidade não neoplásica que ocorre, principalmente em gatas jovens, devido ao estímulo excessivo de progesterona endógena ou exógena. Embora não seja relatada com frequência, sua incidência tem aumentado, especialmente no Brasil, em consequência do uso de anticoncepcionais de longa duração como, por exemplo, acetato de medroxiprogesterona. O objetivo desta revisão sistemática é avaliar as características clínicas e comparar os diferentes tratamentos preconizados para esta patologia. O uso de antiprogestágenos, como o aglepristone, mostrou-se muito eficiente no tratamento da hiperplasia fibroadenomatosa mamária felina por ser uma alternativa pouco invasiva e com resposta clínica mais rápida que os demais métodos

Diferentes esquemas de indução para transplante renal com doador vivo

Abstract Introduction: Indications for induction therapy is not consensual in living donors. Objective: The objective of this study was compare no induction with thymoglobulin and basiliximab induction in the incidence of acute rejection in kidney transplantation with living donor. Methods: We select all cases of renal transplantation with living donor performed in Hospital das Clínicas de Botucatu da UNESP during the period of January 2010 to December 2013. The group was divided by the type of medication used for induction. Results: A total of 90 patients were evaluated. There were no differences in baseline characteristics of age and underlying disease. The rate of biopsy-proven acute rejection was higher in the group without induction (42.9%) compared to basiliximab group (20%) and Thymoglobulin (16.7%), p = 0.04. The rejection by compatibility shows that the identical had the lower rejection rate (10%). The haploidentical group without induction had the highest rejection rates (53.3%). In all distinct group the rejection rates were similar with basiliximab or Thymoglobulin, p = NS. The use of induction therapy was associated independently with a lower risk of rejection (OR = 0.32 CI: 0.11 to 0.93, p = 0.036). There were no differences in renal function at 6 months and patient survival and graft in the three groups. Discussion: The haploidentical patients without induction were those with higher rates of acute rejection. The group of patients induced with Thymoglobulin had a higher immunological risk, however showed low rates of rejection. Conclusion: The use of induction therapy resulted in lower rates of rejection in transplantation with living donor.
