LLLT can improve bone formation process in CSD filled or not with BBG in rat calvaria, but it is not able to accelerate particles resorption of this material in the interior of bone defect.

Despite the improvement in the periimplant indices, there is no sufficient evidence to score the best results or even to choose the best association for nonsurgical treatment of periimplantitis; hence, more trials are necessary to answer this question.

RESUMOIntrodução: A maxila posterior desdentada é muitas vezes um desafio para a instalação de implantes devido à falta de osso, reabsorção do rebordo alveolar e/ou pneumatização seio maxilar. Um dos problemas nessa área é a fístula bucoantral que é caracterizada por uma comunicação patológica, circundada por tecido epitelial, entre a cavidade bucal e seio maxilar. Objetivo: O objetivo do presente relato de caso clínico foi descrever o tratamento de uma fístula bucoantral, desde o diagnóstico até seu completo fechamento, demostrando os métodos e técnicas utilizadas. O diagnóstico foi seguido pelo protocolo proposto por Marzola, sendo analisado a radiografia panorâmica na região do seio maxilar, teste de sensibilidade aos antibióticos, exame de biópsia por citologia esfoliativa e irrigação do seio maxilar com solução adstringente de lauril dietilenoglicol éter sulfonato de sódio e acetilcisteína + glicinato de tianfenicol. O tratamento medicamentoso consistiu em descongestionantes nasais maleato de bronfeniramina + cloridrato de fenilefrina, cloridrato de fexofenadina + cloridrato de pseudoefedrina e cloreto de sódio, a antibioticoterapia com sulfametoxazol + trimetoprima e como analgésico o paracetamol. O tratamento cirúrgico consistiu em incisão linear, deslocamentos do retalho mucoperiostal vestibular e lingual, incisões na base do periósteo, remoção da fístula, alivio da tabua óssea vestibular, sutura simples e festonada. Conclusão: Dentro dos limites do presente caso clínico, podemos concluir que os procedimentos adotados para o diagnóstico e o tratamento da fístula bucoantral foram efetivos, fechando-se completamente a lesão, restabelecendo assim a normalidade do seio maxilar para futuros procedimentos reabilitadores.Descritores: Fístula bucoantral.

Within the limits of this study, it is concluded that methylene blue at pH 1.0 provides better biocompatibility than at pH 7.0.

Autologous fat transfer is a common technique to refine the contour of the breast after prosthetic augmentation or reconstruction, correcting remaining asymmetries by injecting previously harvested fat tissue with a cannula. Current procedures are often performed without visualization of the cannula at the delivery site and may require subsequent verification of the implant’s integrity. The present paper aims to evaluate the safety of a new bulb tip cannula to be used during breast implant procedures for injecting fat adjacent to a breast implant that reduce the risk of damaging the implant. Two conventional cannulae and 3 bulb cannulae, which have an atraumatic distal tip, were tested in a simulated implant-puncture setting in 3 positions (at 0°, 45°, and 90° of incidence). A Tensile Tester (Instron, High Wycombe, UK) was used to apply force with each cannula device and record the amount of force applied in the attempt to penetrate the implants used, with shell layers having a variable thickness. No implant rupture was observed with the bulb tip cannulae regardless of size or the position in which the cannulae were pressed against the implants. The cannula opening was not impeded and tended to bend instead; 27% of the cases with the conventional lipo-cannulae caused an implant rupture. The bulb tip cannula could enhance the safety of the fat transfer procedure by ensuring no iatrogenic implant disruption and optimal delivery of the fat tissue.

Orotracheal intubation is considered the most delicate maneuver performed by anesthesiologists, and failure to manage the airways is one of the main causes of possible complications that can be catastrophic during its performance, thus requiring good team planning. Anatomical and / or physiological characteristics, such as limited mouth opening, a condition often found in patients suffering from fractures of the zygomatic arch or who have some abnormality in the temporomandibular joint (TMJ), can characterize a difficult airway, which demands attention greatest of the professional. Therefore, in order to overcome the obstacles that may occur during a difficult or unexpected intubation, new tools have been used, such as videolaryngoscopy in which an intubation device containing miniature video cameras is used in order to allow the operator has an indirect view of the glottis to increase success rates and decrease intubation time. The aim of the present study is to report a clinical case of a trauma victim, with limited mouth opening, who underwent intubation with the aid of a video laryngoscope after failed attempts at conventional intubation.

Objective The aim of this study was to evaluate the effectiveness of hand debridement (HD) versus ultrasonic dental scaler (UDS) for the treatment of experimental periodontitis (EP) in rats. Material and methods Thirty 3‐month‐old male rats were used. EP was induced around the mandibular first molars (right and left). Seven days after induction, the treatments with either HD (n = 30) or UDS (n = 30) were randomly performed in each molar. Euthanasia were performed at 7, 15, and 30 days after treatment. Histometric (percentage of bone in the furcation [PBF]), histopathological, and immunohistochemical (for detection of tartrate-resistant acid phosphatase [TRAP] and osteocalcin [OCN]). Parametric data (PBF and TRAP) was analyzed by One-way ANOVA followed by Tukey’s post-test. OCN was analyzed by Kruskal-Wallis followed by Student-Newman-Keuls post-test. The level of significance was 5%. Results Group HD presented higher PBF and lower TRAP-immunolabeling at 30 days as compared with UDS in the same period (p≤0.05). Group HD presented higher OCN immunolabeling at 30 days as compared with 7 and 15 days (p≤0.05). Persistent and exacerbated inflammatory process was observed in some specimens from group UDS at 30 days, as well as the bone trabeculae presented irregular contour, surrounded by many active osteoclasts. Conclusion Nonsurgical periodontal therapy with HD resulted in higher PBF and lower expression of TRAP as compared with UDS. Also, HD increased the expression of OCN over time.

Cherubism is described as a rare and benign hereditary bone disease, characterized by a bilateral volumetric increase in the maxillary bones, with a greater predilection for males in childhood. Clinically, it presents as a volumetric enlargement of the mandible and, maxilla, which is generally painless, firm on palpation and varies in relation to size and extension. Its differential diagnosis is the Brown Tumor of Hyperparathyroidism and the Central Lesion of Giant Cells. The diagnosis is based on the assessment of clinical characteristics together with complementary exams. The objective of this study was to carry out a brief review of the literature and report a clinical case of this pathology in a 9-year-old child with a family history of cherubism, assessed through imaging, histopathological and karyotype exams, which continues to be assisted by the oral and maxilofacial surgery team of the Faculdade de Odontologia de Araçatuba - FOA Unesp since the treatment of the cherubism still does not have a definitive protocol.
