ABSTRACT

Abstract In the present study, anthelmintic activities of Arundo (A.) donax L., Areca (Ar.) catechu L., and Ferula (F.) assa-foetida L. were determined. Leaves of A. donax L., latex of F. assa-foetida L. and seeds of Ar. catechu L. in different solvent fractions were subjected to in vitro (egg hatch assay; EHA, and adult motility assay; AMA) and in vivo (faecal egg count reduction test; FECRT) tests of anthelmintic activity using Haemonchus contortus model. In the AMA, crude aqueous methanol extracts (CAME) and ethyl acetate fractions of F. assa-foetida at 10 hr post-treatment showed maximum mortality of H. contortus at 12.5-50 mg mL-1. In the EHA, CAME of F. assa-foetida was identified as a potent ovicide based on its low LC50 (16.9 µg mL-1), followed in order by Ar. catechu and A. donax. Results from the FECRT also showed the extract of F. assa-foetida L. to be more effective than those of Ar. catechu L. and A. donax L., against the gastrointestinal parasitic nematodes. Chloroform and ethyl acetate fractions showed better anthelmintic activities against the adult worms in vitro, while CAME of these plants were better than their crude powders in vivo. It is recommended to document and investigate indigenous knowledge of possible medicinal plants to plan scientific trials that may justify their endorsement.


Resumo No presente estudo, as atividades anti-helmínticas de Arundo (A.) donax L., Areca (Ar.) Catechu L. e Ferula (F.) assa-foetida L. foram determinadas. Folhas de A. donax L., látex de F. assa-foetida L. e sementes de Ar. catechu L. em diferentes frações de solvente foram submetidos a testes in vitro (teste de eclosão de ovos, EHA e ensaio de motilidade em adultos, AMA); e in vivo (teste de redução da contagem de ovos fecais, FECRT) de atividade anti-helmíntica, usando-se Haemonchus contortus. Na AMA, extratos aquosos brutos de metanol (CAME) e frações de acetato de etila de F. assa-foetida. Dez horas pós-tratamento, apresentaram mortalidade máxima de H. contortus em 12,5-50 mg mL-1. No EHA, CAME de F. assa-foetida foi identificado como um ovicida potente baseado em seu baixo LC50 (16,9 µg mL-1), seguido em ordem por Ar. catechu e A. donax. Os resultados do FECRT também mostraram que o extrato de F. assa-foetida L. é mais eficaz do que o de Ar. catechu L. e A. donax L., contra nematoides parasitas gastrointestinais. As frações clorofórmio e acetato de etila mostraram melhores atividades anti-helmínticas contra vermes adultos in vitro, enquanto o CAME dessas plantas foi melhor do que o pó bruto in vivo. Recomenda-se documentar e investigar o conhecimento indígena de possíveis plantas medicinais para planejar ensaios científicos que possam justificar seu endosso.

ABSTRACT

Objetivo: Comparar la eficacia de la inmovilización nocturna de la muñeca con una férula cubital en ángulo neutro junto con la aplicación de ultrasonido en pacientes con síndrome del túnel carpiano leve y moderado. Materiales y Métodos: Entre octubre de 2007 y marzo de 2010, se incluyó a pacientes >18 años con síndrome del túnel carpiano confirmado por electromiografía en un hospital de Buenos Aires. Se realizó una aleatorización estratificada, con bloques permutados aleatorios, y apareamiento por sexo y edad. Los pacientes fueron asignados al grupo experimental (GE) o al grupo de control (GC). Ambos grupos recibieron ultrasonido de 1 MHz pulsante por 15 min, 3 veces por semana, durante 6 semanas. Los pacientes del GE, además, utilizaron una férula nocturna. Se evaluaron el dolor y la parestesia con la escala analógica visual de 100 mm, la PSFS y el test de Moberg, al comenzar, a las 3 semanas y, al finalizar, a las 6 semanas, y durante el seguimiento, al mes, y a los 3 y 6 meses, con evaluador a ciego. Resultados: Se analizó a 32 pacientes del GC y a 33 del GE. Al finalizar el tratamiento, todas las variables habían mejorado en ambos grupos, con diferencia de medias estadísticamente significativa para el dolor a favor del GE a las 3 semanas de tratamiento 1,64 (IC95% 0,38-2,91; p = 0,012), pero sin diferencia clínica significativa. No se informaron efectos adversos. Conclusión: El tratamiento con una férula nocturna y ultrasonido no es superior al ultrasonido solo en pacientes con STC. Nivel de Evidencia; II


Objective: To compare the effectiveness of night wrist immobilization using an ulnar splint in neutral angle versus the use of ultrasound (US) in patients with Carpal Tunnel Syndrome (CTS). Materials and Methods: Study population included over 18 years of age that were treated for electromyography-confirmed CTS between October 2007 and March 2010 at a Buenos Aires hospital. A sex- and age-stratified randomization was performed by using randomly permuted blocks, allocating patients into the experimental group (EG) and control group (CG). Pulsed US therapy was administered for 15 minutes to all patients three times a week for six weeks at a frequency of 1 MHz. In addition, EG patients were also prescribed night splint. Pain and paresthesia were evaluated using a 100mm Visual Analogue Scale (VAS), the Patient Specific Functional Scale (PSFS), and the Moberg pickup test (MPUT) at baseline, at 3 and 6 weeks, and at 3 and 6 months after treatment institution by a blinded investigator. Results: Study population consisted of 85 cases (65 patients) that were randomly allocated to CG (n=42) or EG (n=43). Improvement of all the variables was observed at the end of treatment in both groups, with a 1.64 (95% CI: 0.38-2.91, P=0.012) statistically significant difference in means for pain in favor of the EG at 3 weeks of treatment, but without a significant clinical difference. No adverse effects were observed. Conclusion: The effectiveness of combined night splint and US therapy is not superior to the US alone treatment in CTS patients. Level of Evidence; II

ABSTRACT

Objective: The aim of this study was to evaluate the effects of using different diameters of parallel cast posts with, or without ferrule, on the overall fracture resistance of Cast Post and Core (CPC). Material and Methods: Forty (40) endodontically treated human maxillary central incisors were divided into four groups (n=10): [F1] 1.0 mm diameter post with ferrule; [NF1] 1.0 mm diameter cast post without ferrule; [F1.5] 1.5 mm diameter cast post with ferrule; [NF1.5] 1.5 mm diameter post without ferrule. For all teeth, the post space (9.0 mm, in depth) was prepared using ParaPostTM drill. CPC using base metal alloy were fabricated and were cemented using resin modified glass ionomer (RMGI) cement along with the Porcelain Fused to Metal (PFM) crowns. A universal testing machine (Instron) was used to apply horizontal force perpendicular to the long axis of the tooth at the center of lingual surface, until catastrophic failure. Data was submitted to two-way ANOVA and Scheffé tests (P<0.05). Results: Both post diameter and ferrule statistically affected the maximum load at fracture (P=0.004 and P=0.013, respectively). The highest mean values were observed for samples with ferrule and wider post size (490N), while the lowest were observed for samples without ferrule and narrower post size (254N). There was no relationship between the presence of a ferrule and post size (P=0.937). Conclusion: For endodontically treated teeth with no ferrule, a wider-diameter cast post increased fracture resistance of a CPC and PFM crown procedure. (AU)


Objetivo: O objetivo do presente estudo foi avaliar os efeitos de diferentes diâmetros de núcleos metálicos paralelos (com ou sem férula) na resistência a fratura do procedimento restaurador. Material e Métodos: Quarenta (40) incisivos centrais superiores humanos foram tratados endodonticamente e divididos em quarto grupos (n=10): [F1] Diâmetro de 1.0 mm, com férula; [NF1] Diâmetro de 1.0 mm, sem férula; [F1.5] Diâmetro de 1.5 mm, com férula; [NF1.5] Diâmetro de 1.5 mm, sem férula. Para todos os dentes, o espaço foi preparado para o núcleo (9.0 mm, em comprimento) utilizando brocas do ParaPostTM. Os núcleos metálicos e as coroas metalocerâmicas fabricadas foram cimentados utilizando-se cimento de ionômero de vidro modificado por resina. Uma máquina de ensaios universal (Instron) foi utilizada para aplicar uma força horizontal perpendicular ao longo eixo do dente, no centro da face lingual, até falha catastrófica. Os dados foram analisados através de análise de variância de dois fatores e teste de Scheffé (p<0.05). Resultados: O diâmetro do núcleo e a presença (ou ausência) de férula afteram estatiscamente a resistência máxima a fratura do procedimento (P=0.004 e P=0.013, respectivamente). Os maiores valores foram observados para amostras com férula e de maior diâmetro (490N), enquanto os menores valores foram observados para amostras sem férula e de menor diâmetro (254N). Conclusão: Para dentes tratados endodondicamente, com férula, um núcleo de maior diâmetro aumentou a resistência a fratura de procedimentos restauradores envolvendo coroas metalocerâmicas cimentadas sobre núcleos metálicos fundidos.

ABSTRACT

In this paper,the effects of active fractions of Ferula ferulaeoides on the growth and apoptosis of human gastric cancer cell MGC-803 transplantation tumor were systematically studied. The subcutaneous ectopic transplantation tumor model was established in human gastric cancer MGC-803 nude mice by cell suspension implantation method. The anti-tumor rate and organ index were used to evaluate the anti-tumor effect of the active fractions of F. ferulaeoides on the tumor-bearing nude mice. HE staining,TUNEL staining,RT-PCR,Western-blot and ELISA were used for pathological examination,apoptosis observation,and detection of apoptosis-related genes,proteins and cytokines expression. The results showed that as compared with the model group,the low,medium and high doses of the active fraction of F. ferulaeoides had inhibitory effects on xenografts in nude mice,respectively,in a dose-dependent manner; the apoptotic ratio was increased with the increase of drug concentration. As compared with the model group,F. ferulaeoides could down-regulate the expression of survivin mRNA in nude mice,and the protein expression levels of Bax,Bcl-2,caspase-3 and caspase-9 in tumor tissues of nude mice could be increased to different degrees in F. ferulaeoides groups. The contents of IL-10 and TGF-β1 in plasma of nude mice were decreased in high dose group of F. ferulaeoides active fractions. The results indicated that F. ferulaeoides can significantly inhibit the growth of human gastric cancer MGC-803 subcutaneously transplanted tumor,and its mechanism may be related with down-regulating the expression of survivin mRNA,and up-regulating the expression of apoptosis-related proteins Bax,caspase-3 and caspase-9.

ABSTRACT

La investigación tuvo como objetivo rediseñar la órtesis utilizada post-tratamiento Ponseti, en niños con pie equino varo congénito, de forma tal que permita la reducción de rechazo a su uso. Método: Se identificaron las necesidades de los niños con pie equino varo congénito, para verificar los inconvenientes con respecto a la funcionalidad, diseño y adaptabilidad a la órtesis dado que si la férula no se usa adecuadamente el riesgo de recidiva es de 80 %, por el contrario con el uso de la férula el riesgo es de 4 %. Se realizó un estudio biomecánico del movimiento de un paciente durante el gateo, con y sin la órtesis. Resultados: Se elaboró un modelo 3D de la propuesta, para simular el diseño sometido a las fuerzas generadas por los bebés durante el pataleo en posición supina. Se evaluó experimentalmente el desempeño del prototipo alfa, para determinar si cumplía con la meta prevista. Se obtuvo la fabricación y pruebas de la órtesis en plataforma virtual y físico. Acorde al alcance del proyecto, se determinó que es probable que se reduzca el rechazo al uso y por consiguiente la formación de recidiva, al reducir los factores determinantes propios de la férula del mercado, que propiciaban el mal uso de esta en el tratamiento. La velocidad promedio de gateo es de 0.48 m/s y con la férula se reduce a 0.37 m/s. Discusión: La férula del mercado pesa 304.07 g y la propuesta pesa 209.26 g. Se sugiere que se continúe la investigación en el estudio biomecánico.


This research was developed with the objective of redesigning the orthosis used in the post- Ponseti treatment in children with clubfoot, with the intention of reducing the rejection to its use. Method: A research on the needs of children with congenital clubfoot was conducted to identify the disadvantages on functionality, design and adaptability of the orthosis if the splint is not used appropriately, the risk of relapse is 80 %, whereas using the splint, the risk is 4 %. A biomechanical study of a patient's movement during the crawl was performed with and without the orthosis. Results: A 3D model of the design was developed to simulate computationally its performance under the forces generated by the babies during the kick in supine position. Finally, an experimental evaluation of the alpha prototype performance was made to determine whether it met the intended goal. Thus, the manufacturing and testing of the orthosis on virtual and in physical platform took place. Taking in account the goal of this project, it 3 was determined that it is possible to reduce the reject to the use and therefore the formation of relapse by reducing the determinant factors of the common market splint, which promotes its incorrect use of this in the treatment. The average crawl speed is 0.48 m/s and with the splint, it decreases to 0.37 m/s. Discussion: The weight of the common market splint is 304.07 g and the weight of the one designed in the study is 209.26 g. Further biomechanical research is suggested to get conclusive results

ABSTRACT

Objetivo: Analizar la distribución de tensiones que provoca una fuerza axial en el modelo tridimensional, con elmétodo de elementos finitos, en la prótesis parcial fija implantosoportada con voladizo distal (PPFIVD) sobre implantes dentales cortos en el sector posterior del maxilar parcialmente desdentado. Materiales y métodos: Se crearon modelos geométricos del maxilar. Se diseñaron dos grupos y cuatro subgrupos. En zona premolar, se ubicaron implantes cortos StandardPlus SLA® (Straumann) de diferentes longitudes. Grupo A: PPFIVD con dos implantes, GA1 de 8 mm y GA2 de 4 mm. Grupo B: PPFIVD con un implante, GB1 de 8 mm y GB2 de 4 mm. Se aplicó una fuerza axial de 100 N a 30°.Resultados: La distribución de las tensiones en los implantes fue menor en GA1 que en GA2, y en GB1 que enGB2. A nivel óseo, la distribución de las tensiones fue mayor en GA1 que en GA2, y en GB2 que en GB1. Se observaron microdeformaciones óseas periimplante y, posteriormente, desplazamiento del conjunto prótesis/implante. Conclusiones: La PPFIVD sobre dos implantes de 8 y4 mm ferulizados podría ser una alternativa viable al levantamiento del piso de seno maxilar. La PPFIVD sobre un implante de 4 mm no sería recomendable. Las tensiones elevadas provocaron menor rendimiento en geometría oseoimplantaria, evidenciando microdeformaciones en el tejido óseo tridimensional y desplazamientos de la PPFIVD.

ABSTRACT

El autotrasplante se refiere a la transferencia quirúrgica de un dientede una posición a otra en el mismo individuo dentro de los alveolosde dientes extraídos o sitios preparados quirúrgicamente. El autotrasplante de un diente inmaduro puede ser una opción para reemplazarmolares con caries extensas en pacientes jóvenes como una alternativaal reemplazo de dientes con prótesis fi ja o implanto-soportada. Es unprocedimiento clínico con un índice de éxito de 98 por ciento cuando los dientes son trasplantados traumáticamente y el tiempo extraoral se mantiene al mínimo. El estado de desarrollo del diente determina ampliamente el potencial de reparación pulpar después del autotrasplante. Para obtener una pulpa vital en un diente autotrasplantado el foramen apical no debe medir menos de1 mm de diámetro. El área receptora debe ser 1-2 mm más grande y profunda que las medidas de las raíces donadoras parapreservar las células del ligamento periodontal, un óptimo contacto entreambas estructuras puede mejorar el suministro sanguíneo y los nivelesde nutrición de las células del ligamento periodontal, el cual puedeincrementar el éxito del autotrasplante. En este artículo se presenta un caso exitoso de autotrasplante de tercer molar inmaduro.


Autotransplantation refers to the surgical transfer of a tooth fromone position to another in the same individual onto extracted toothsockets or surgical prepared recipient sites. Autotransplantation of animmature teeth can be an option to replace extensive decayed molarsin young patients as an alternative to immediately replacing teeth withfi xed or implant-supported prosthesis. Autotransplantation is a clinicalprocedure with a success rate of 98% when teeth are transplantedatraumatically and when the extraoral time is keep to a minimum.The developmental stage of the tooth highly determines the potentialof pulpal repair after transplantation. To obtain a vital pulp in anautotransplanted tooth, the apical foramen should not be smaller than1 mm in diameter. The recipient area must be 1-2 mm larger and deeperthan the measurements of the donor roots to preserve the periodontalligament cells, an optimal contact between both structures can improvethe blood supply and the level of nutrition to the periodontal ligamentcells, which can increase the success of autotransplantation. In thispaper, we report one case of successful autotransplantation of animmature third molar.

ABSTRACT

Actualmente, es frecuente la consulta por trastornos temporomandibulares (TTM) en la clínica odontopediátrica, siendo reconocida la múltiple causalidad de los mismos. Se presenta la resolución de una situación clínica de una paciente de 13 años de edad que acudió a la Cátedra de Odontología Integral Niños (OIN), presentando dolor muscular y articular del lado derecho, limitando la apertura bucal a 25 mm confortable y a 28 mm forzada, con desvío de la mandíbula hacia la izquierda. Refería haber sido atendida en una guardia médica el día anterior con bloqueo en apertura, luego de 8 meses de evolución, con síntomas de chasquido y doloir, sin haber realizado consulta alguna. Se indicó tratamiento sintomático y se solicitaron estudios complementarios. El diagnóstico fue de luxación discal sin reducción. Con la evaluación integral, se hallaron factores concomitantes, tales como maloclusión, hiperlaxitud, respiración bucal y parafunciones. En el abordaje terapéutico, se colocó un intermediario oclusal para reposicionamiento mandibular, se realizó tratamiento fonoaudiológico miofuncional y reeducación postural global (RPG). La paciente evolucionó favorablemente; a los 6 meses resolvió el ruido articular y al año estaba asintomática, con 37 mm de apertura, comenzando su tratamiento de ortodoncia y manteniendo controles durante 4 años. El compromiso de la familia y la participación de un equipo de trabajo, permitió la resolución integral del caso. El odontopediatra tiene la responsabilidad de alertar a padres y pacientes sobre factores de riesgo, diagnosticar TTM y orientar los tratamientos, involucrándose cuando corresponde su intervención, o derivando en forma oportuna...

ABSTRACT

To study the ecological distribution and diversity of endophytic fungi associated with Ferula of medicinal plants in Xinjiang. The endophytic fungi were isolated from roots, stems and leaves of Ferula by microbiology research methods and technology. The endophytic fungi were identified using ITS rDNA sequence analysis and morphology analysis. The composition, diversity and preference of endophytic fungal community were analyzed with Shannon-Wiener biodiversity index (H') and Sorensen coefficient (Cs). A total of 337 strains endophytic fungi were isolated and classified into 38 genera, Alternaria, Aureobasidium and Fusarium were the dominant genera. Among the 337 isolates, the endophytic fungi of F. sinkiangensis were the most, The Shannon-Wiener biodiversity index (H') associated with roots of F. fukanensis was the highest, reached 1.85. The highest Sorensen coefficient ( Cs) was between leaf of F. sinkiangensis and leaf of F. ovina, reached 0.75. From the result, endophytic fungi were widely distributed in six Ferula, there are some notable differences between distribution and composition of the endophytic fungi isolated from different issues and different species of Ferula, show a certain degree of species and tissue preference. The results obtained in this study will provide realistic basis and theoretical basis for further study the secondary metabolites of endophytic fungi associated with Ferula, and the relationship between endophytic fungi and their host plants.

ABSTRACT

OBJECTIVES: The usage of medicinal plants as natural antimicrobial agents has grown in many fields including dental medicine. The aim of this in vitro study was three-fold: (i) to determine the chemical compositions of the Ferula gummosa essential oil (FGEO), (ii) to compare the antimicrobial efficacy of the oil with sodium hypochlorite (NaOCl) and chlorhexidine (CHX), (iii) to assess the toxic behavior of FGEO in different concentrations compared to 5% NaOCl and 0.2% CHX. MATERIALS AND METHODS: Gas chromatography/mass spectrometry (GC/MS) was used to determine the chemical compositions of the oil. The disk diffusion method and a broth micro-dilution susceptibility assay were exploited to assess the antimicrobial efficacy against Enterococcus faecalis, Staphylococcus aureus, Streptococcus mitis, and Candida albicans. The cytocompatibility of the FGEO was assessed on L929 fibroblasts, and compared to that of NaOCl and CHX. RESULTS: Twenty-seven constituents were recognized in FGEO. The major component of the oil was beta-pinene (51.83%). All three irrigants significantly inhibited the growth of all examined microorganisms compared to the negative control group. FGEO at 50 microg/mL was effective in lower concentration against Enterococcus faecalis than 5% NaOCl and 0.2% CHX, and was also more potent than 0.2% CHX against Candida albicans and Staphylococcus aureus. FGEO was a cytocompatible solution, and had significantly lower toxicity compared to 5% NaOCl and 0.2% CHX. CONCLUSIONS: FGEO showed a promising biological potency as a root canal disinfectant. More investigations are required on the effectiveness of this oil on intracanal bacterial biofilms.

ABSTRACT

Secondary somatic embryogenesis leads to the formation of abnormal somatic embryos and produces abnormal seedlings. Normal plants are difficult to obtain from these embryos, due to the asynchronous maturation of the embryogenic tissues and low germination and conversion rates. The effects of some media additives and different strengths of MS medium on germination and plantlet formation of in vitro derived somatic embryos of Ferula Assa-foetida were studied. The highest number of normal embryos was observed in MS medium containing 30g/l sucrose with 0.5% or 1% AC and in MS medium supplemented with PEG and 0.5% or 1% AC. The treatments of MS medium with 30g/l sucrose and 0.5% AC × MS medium containing sorbitol and MS medium containing PEG and 1% AC × ½ MS had maximum number of normal germinated embryos without secondary somatic embryogenesis (SSE). In some of the treatments the embryos were converted better than the others, such as; the interaction effect of MS medium with 30g/l sucrose and 0.5% AC× MS, MS medium with 30g/l sucrose × MS medium with glutamine. Using different strength of MS medium and presence of some media additives is effective on germination and conversion of somatic embryos into normal plantlet. Presence of Activated Charcoal in the culture medium can reduce secondary somatic embryogenesis.

ABSTRACT

El autotrasplante dentario se refiere al traslado de una pieza dentaria de su alveolo a otro sitio, alveolo post-extracción o alveolo quirúrgico, en la misma persona. El trasplante dentario ha sido practicado durante siglos, pero generalmente fracasaba por complicaciones en la cicatrización, debido a la falta de conocimiento acerca de la etiología de la reabsorción radicular y el control de la infección. Las investigaciones realizadas en los últimos años tornaron predecible el pronóstico del mismo, demostrando buena supervivencia y brindando una alternativa para la rehabilitación ante la pérdida dental en individuos jóvenes y niños

ABSTRACT

La pérdida de rango de movimiento pasivo (PROM) en las articulaciones interfalángicas de la mano es una secuela común tras lesiones traumáticas. A pesar de que el uso de férulas se ha convertido en una modalidad terapéutica ampliamente aceptada para mejorar el PROM, existe muy poca evidencia empírica que guíe en la prescripción de férulas. El presente estudio investiga el efecto del uso de férulas correctoras en contracturas en fexión de la articulación interfalángica proximal (IFP) de los dedos de la mano tras una lesión traumática. Diecisiete pacientes con una contractura en fexión de la IFP tras una lesión traumática como consecuencia de un accidente laboral participaron en este estudio experimental. Mediante un goniómetro digital se valoró el PROM de la articulación IFP de dichos pacientes y se les asignó de manera aleatoria a uno de los dos grupos de férulas. A los pacientes del grupo A se les colocó una férula de extensión dinámica de la IFP y a los del grupo B se les colocó una férula de extensión estática. El PROM de la articulación se volvió a valorar con un goniómetro en el momento en el que los pacientes recibieron el alta laboral. Los resultados indicaron mejorías signifcativas en ambos grupos en la corrección de la contractura en fexión (p<0,05). La diferencia entre los pacientes que usaron la férula dinámica frente a los que usaron la férula estática no fue estadísticamente signifcativa. Ambos tipos de férulas pueden ser recomendadas para el tratamiento de contracturas en fexión inferiores a 35º de la IFP tras una lesión traumática.


Reduced passive range of motion (PROM) of the interphalangeal joints of the hand is a common consequence after a traumatic injury.Although mobilizing splinting has become a rehabilitative approach widely accepted by therapists to improve PROM, limited empirical evidence is available to guide in its prescription. This study investigates the effect of corrective splinting on fexion contracture of the fnger proximal interphalangeal joints (PIP) after a traumatic injury of the hand. Seventeen patients with fnger fexion contracture of the PIP as a result of an industrial accident participated in the experimental study. The passive range of motion of the PIP joint was measured with a fnger goniometer and patients were randomly allocated to one of two splint programs. Subjects in group A were given dynamic extension splints, and subjects in group B were given static splints. PROM was re- assessed with a goniometer once the patient was discharged and started working again. Results indicated signifcant improvement in both groups in the correction of the fnger fexion contracture (p<0,05). Patients with dynamic fnger extension splints did not differ signifcantly from those with static splints in extension gains. Both types of splints can be recommended for fexion contractures of 35 degrees or less in the PIP joint after a traumatic injury.

ABSTRACT

El mucocele (MC) es la lesión más común de la mucosa bucal, como consecuencia de una alteración de las glándulas salivales menores. El tratamiento habitual es quirúrgico y consiste en la resección de la lesión. El objetivo de esta comunicación es presentar una modalidad de intervención multiprofesional no quirúrgica para el tratamiento del MC. Se presenta un estudio de caso que describe el proceso de atención psicológica - fonoaudiológica - odontológica, empleando una pantalla bucal con el propósito de reducir el trauma sobre la lesión del MC, que desaparece sin necesidad de recurrir al tratamiento quirúrgico
