ABSTRACT

SCOPE: Nonalcoholic fatty liver disease (NAFLD) has a high and growing prevalence globally. Mitochondria are fundamental in regulating cell energy homeostasis. Nevertheless, mitochondria control mechanisms can be exceeded in this context of energy overload. Damaged mitochondria worsen NAFLD progression. Diet and lifestyle changes are the main recommendations for NAFLD prevention and treatment. Some polyphenols have improved mitochondrial function in different NAFLD and obesity models. OBJECTIVE: The study aims to discuss the potential role of polyphenols as a nonpharmacological approach targeting mitochondria to prevent and treat NAFLD, analyzing the influence of polyphenols' chemical structure, limitations and clinical projections. METHODS: In vivo and in vitro NAFLD models were considered. Study searches were performed using the following keywords: nonalcoholic fatty liver disease, liver steatosis, mitochondria, mitochondrial activity, mitochondrial dynamics, mitochondrial dysfunction, mitochondrial morphology, mitochondrial cristae, fusion, fission, polyphenols, flavonoids, anthocyanins, AND/OR bioactive compounds. CONCLUSION: Polyphenols are a group of diverse bioactive molecules whose bioactive effects are highly determined by their chemical structure. These bioactive compounds could offer an interesting non-pharmacological approach to preventing and treating NAFLD, regulating mitochondrial dynamics and function. Nevertheless, the mitochondria' role in subjects with NAFLD treatment is not fully elucidated. The dosage and bioavailability of these compounds should be addressed when studied.

ABSTRACT

Introducción: El tratamiento de caninos incluidos maxilares, se basa prin cipalmente en la tracción ortodóntica. Cuando esta fracasa, se suele plantear como alternativa la extracción del canino y la posterior colocación de un implante dental. El autotrasplante se plantea como opción de tratamiento siempre que la extracción íntegra del canino sea viable ya que aporta muchas ventajas como la capacidad de ser movilizados con ortodon cia.Caso clínico: Se describe un caso clínico en el que se realizó un autotrasplante de un canino incluido tras haber fracasado la tracción en una paciente joven. Tras realizar una cirugía regenerativa, fue sometida a tratamiento de ortodoncia y restaurador. Después de 20 meses de seguimiento la paciente se encuentra asintomática, sin signos de movilidad ni reabsorción y con un estable estado periodontal de dicho diente.Conclusión: A pesar de las limitaciones, se puede concluir que siempre que sea viable, el autotrasplante puede constituir una alternativa válida cuando la tracción ortodóntica no funciona, principalmente en pacientes jóvenes en los que no están indicados los implantes (AU)


Introduction: The main treatment of impacted canines is orthodontics. In case of failure, extraction of the canine and the subsequent placement of a dental implant is given as an alternative. Autotransplantation is considered a treatment option as long as the full extraction of the canine is viable, because it provides many advantages as the ability of mobilization with orthodontics Case report: Description of a clinical case in which an autotransplantation of an included canine was carried out after traction failed in a young patient. After regenerative surgery was realized in its surroundings the patient underwent orthodontic and restorative treatment. 18 months of follow–up later the patient remains asymptomatic, with no mobility or resorption signs and with a healthy periodontal state in said canine. Conclusion: Autotransplantation can be a suitable alternative when orthodontic traction has failed, as long as it is viable, especially in young patient when implants are not recommended (AU)

ABSTRACT

Introducción: Las técnicas implantológicas demandan la existencia de unas estructuras óseas adecuadas en calidad y cantidad para alojar las fijaciones oseointegradas de un modo predecible. En ocasiones, el sustrato óseo es insuficiente, por lo que son necesarias técnicas de reconstrucción/regeneración ósea que precisan de un cierre primario completo para asegurarnos que los fenómenos que conducirán a la formación de nuevo tejido óseo se sucedan. El objetivo de este estudio es mostrar una serie de ocho casos clínicos donde la ‘Double Flap Incision Technique modificada’ nos sirve para reconstruir zonas de defecto óseo en la región mandibular posterior que limitaban la colocación de fijaciones oseointegradas. Métodos: Se realiza un estudio prospectivo de ocho casos clínicos procedentes de nuestra práctica privada, con déficit óseo en la zona posterior mandibular en pacientes demandantes de un tratamiento rehabilitador con prótesis fija implantosoportada. En todos los casos se utilizó la denominada ‘Double Flap Incision Technique modificada’ (DFITm). Resultados: En todos los casos conseguimos un cierre primario completo a los 15 días y fue posible la colocación de los implantes en la zona regenerada con criterio protésicamente guiado. Conclusión: La técnica de doble colgajo ‘Double Flap Incision Technique modificada’ nos permite llevar a cabo un adecuado cierre primario sin tensión en casos que requieran una reconstrucción o regeneración ósea, evitando la aparición de dehiscencias que conllevarían al fracaso del tratamiento (AU)


Introduction: Dental implants’ techniques needed to appropiate high-quality bones structures which can support osteointegration bindings in a predictable way. Occasionally, bone substrate is not the suitable one, it is for that reason that we need bone reconstruction and regeneration techniques in which we have to make a complete wound healing in order to guarantee bone regeneration in a correct way. The aim of this article is to comment eight case reports in which we used ‘Double flap incision technique’ to repair bone loss in posterior mandibular region. Methods: We have carried out a pilot study in about eight cases reports whose patients had bone loss in posterior mandibular region and treated with a dental implants’ repair treatment. ‘New Double Flap Incision Technique’ was used in all the cases we report. Results: We obtained an appropiate and complete wound healing in 15 days. In addition, dental implants were positionated in regenerated region correctly in all cases. Conclusion: This ‘New Double Flap Incision Technique’ provide us a way to obtain complete wound healing with no strain in cases which needed bone regeneration or reconstruction, avoid the presence of dehiscences which fail the treatment (AU)
