Use of alveolar distraction osteogenesis for anterior maxillary defect reconstruction.

Alveolar osteogenic distraction (AOD) is a biological process through which new bone formation occurs between bone segments that are gradually separated by incremental traction. This case report described the oral rehabilitation with dental implants of a patient with a vertical bone defect in the maxillary anterior region using the AOD technique. The patient presented with absence of the teeth 22, 21, 11, and 12 associated with a vertical bone defect. The AOD was performed using a supported osteodistractor device surgically installed with subsequent daily activations. After 21 days, the ideal positioning of bone fragment was confirmed and activation was ceased. Five months after the initial surgery, two dental implants were installed in the region of teeth 12 and 22. An FP3 metal-ceramic prosthesis was installed offering satisfactory esthetic results. In conclusion, the use of AOD to increase the alveolar ridge was effective and ensured rehabilitation with dental implants.

Successful Use of Leukocyte Platelet-Rich Fibrin in the Healing of Sinus Membrane Perforation: A Case Report.

PURPOSE: The aim of this case report was to demonstrate the repair of a large sinus membrane perforation related to a sinus floor augmentation procedure, using leukocyte platelet-rich fibrin (L-PRF), for subsequent rehabilitation of a partially edentulous patient. MATERIALS AND METHODS: The patient presented the absence of teeth numbers 18, 17, and 16, associated with insufficient bone height because of the maxillary sinus pneumatization. A maxillary inlay bone graft was proposed, however, during the sinus floor augmentation procedure, a large portion of the sinus membrane was ruptured. To avoid interruption of the surgical procedure, membrane mending was proposed using L-PRF and collagen membranes. RESULTS: After 8 months, 2 external hexagon connection dental implants were placed in the 16 and 17 teeth regions, and a screw-retained implant-supported prosthesis was installed. CONCLUSION: The use of L-PRF associated with collagen membrane was efficient for the sealing of the sinus membrane perforation and enabled bone formation for subsequent implant installation.

Multidisciplinary approach to oral rehabilitation with dental implants after gunshot injury: A clinical report.

This clinical report describes a multidisciplinary approach to treat a patient with edentulism and a severe anatomic defect in the mandible caused by a gunshot injury by using an implant-fixed complete dental prosthesis. An immediate loading interim implant-fixed complete dental prosthesis in the mandible associated with a maxillary removable complete denture prosthesis was initially provided to restore the intermaxillary relation. Nasal floor elevation and maxillary sinus augmentation were subsequently performed to increase the maxillary bone volume. Definitive implant-fixed complete dental prostheses were placed in both arches in order to rehabilitate this initially compromised anatomic condition, which ensured patient satisfaction and improvement in masticatory function and esthetics.

Concentração alcoólica de antissépticos bucais comercializados no brasil no início da segunda década do Séc. XXI / Alcohol concentration of oral antiseptics marketed in Brazil at the beginning of the second decade of the century XXI / Alcohol concentration of oral antiseptics marketed in Brazil at the beginning of the second decade of the century XXI

Introdução: Os antissépticos bucais costumam ser utilizados pela população de forma indiscriminada comométodo auxiliar na higiene bucal. A maioria desses produtos contém o álcool (etanol) na sua composição, quepode provocar lesões à mucosa bucal. Objetivo: Esse estudo visa determinar qualitativamente e quantitativamente a presença de etanol nos enxaguatórios e avaliar se a concentração alcoólica encontrada está de acordo com a concentração alcoólica informada pelos fabricantes dos bochechos mais disponíveis no Brasil. Métodos: A amostra foi composta por 26 colutórios, que foram submetidos ao método de Cordebard modificado para determinação da média das concentrações alcoólicas. Resultados: Dos 26 produtos testados, apenas 5 (19,23%) realmente não continham etanol na sua composição. Um dado preocupante é o fato de ter sido encontrado álcool, mesmo que em baixa concentração, em 2 (7,69%) colutórios que afirmam não possuírem etanol na sua composição. Nesse estudo, também foi observado que 11 (42,31%) bochechos apresentaram uma concentração alcoólica superior a 10% (Concentração alcoólica máxima recomendada para pessoas acima de 10 anos pela Food and Drug Administration) Conclusões: Recomenda-se que os níveis de álcool, quando utilizados nos antissépticos bucais, devem ser apenas o suficiente para desempenhar o seu papel de solvente e estabilizador

Introduction: Oral antiseptics are usually used by the population indiscriminately as an auxiliary method in oral hygiene. Most of these products contain alcohol (ethanol) in its composition, which can damage the oralmucosa. Objective: This study aims to determine qualitatively and quantitatively the presence of ethanol inmouthwashes and assess whether the alcohol concentration found in oral rinses is in accord with the alcoholconcentration reported by the manufacturers of the most available mouthwashes in Brazil. Methods: Thesample consisted of 26 mouthwashes, which underwent Cordebard modified method to determine the averagealcohol concentrations. Results: Of the 26 products tested, only 5 (19.23%) actually contained no ethanol inits composition. A worrying statistic is the fact that it was found alcohol, even if in low concentration, in 2 (7.69%) mouthwashes that claim they have no ethanol in its composition. In this study, it was also observed that 11 (42.31%) mouthwashes showed alcohol concentration superior to 10% (maximum alcohol concentration recommended for people over 10 years of age by the Food and Drug Administration). Conclusions: It is recommended that the levels of alcohol, when used in oral antiseptics, be just enough to play their role of solvent and stabilizer

Prevalencia de accidentes ocupacionales en estudiantes de odontología de la Universidad Federal de Río Grande del Norte, Brasil / Prevalence of occupational accidents in dental students at the Rio Grande do Norte Federal University, Brazil

El objetivo de este estudio fue determinar la prevalencia de accidentes ocupacionales en estudiantes de Odontología de la Universidad Federal de Rio Grande del Norte (UFRN), Brasil y el nivel de conocimiento de estos sobre exposición ocupacional, medidas preventivas y manejo post exposición. Los datos fueron recogidos a través de un cuestionario, con información referente a edad, género y período cursado, además de la ocurrencia de accidentes ocupacionales, medidas pre y post exposición de 150 estudiantes. Los datos fueron registrados en un banco de datos del Statistical Package for the Social Science (SPSS) 17.0 y sometidos a análisis descriptivo. De los 150 estudiantes evaluados, 45.3% eran hombres y 54.7% mujeres. La prevalencia de accidentes fue de 45.3%, ocasionados por perforación durante el lavado y condicionamiento del instrumental (30.9%) o en procedimientos clínicos (21.8%), por salpicaduras en el ojo (11.8%), contacto directo con sangre (10.9%) y por otras causas (24.6%). De los 68 accidentados, solo 14.7% se realizó exámenes para detectar infección por HBV y/o VIH después del accidente, 86.8% de los estudiantes no recibió ningún tratamiento. De la muestra, 88.7% estaban vacunados contra la hepatitis B y de estos, 48.7% completaron el esquema de vacunación. A pesar de que los estudiantes de Odontología presentaron un adecuado conocimiento sobre medidas preventivas y manejo post exposición, hubo una considerable prevalencia de accidentes ocupacionales e inadecuadas conductas post exposición, reflejando la necesidad de la adopción y/o intensificación de programas preventivos, garantizado el egreso de profesionales con alto nivel de preparación en materia de riesgo laboral.

The aim of this study was to determine the prevalence of accidents in dental students at the Federal University of Rio Grande do Norte (UFRN), Brazil, and the knowledge level about their occupational exposure, preventive measures and post-exposure management. Were collected through a questionnaire, data on age, sex and academic semester, as well as the occurrence of accidents, pre and post-exposure. Were recorded in the database of the Statistical Package for the Social Sciences (SPSS) 17.0 and submitted to a descriptive analysis. Of the 150 students evaluated, 45.3% were men and 54.7% women. The prevalence of accidents was 45.3%, caused by drilling in the wash of instrumental (30.9%) or dental procedures (21.8%), due to splash in the eye secretion (11.8%), direct contact with blood (10.9%) and other causes (24.6%). Of the 68 victims, only 14.7% were tested for HBV infection and / or HIV and after the accident, 86.8% of students did not undergo any treatment. Of the sample, 88.7% were vaccinated against hepatitis B and of these 48.7% completed the vaccination schedule. Despite the dental students have an adequate knowledge of preventive measures and post-exposure management, there was a considerable prevalence of occupational accidents and inappropriate behavior after exposure, reflecting the need for adoption or intensification of preventive programs, ensuring the egress of professionals with a high level of preparedness in biohazard.
