ABSTRACT
Objective: to compare, through a systematic review and a meta-analysis, the clinical effect of the adhesive strategies of universal adhesives (UA) in the treatment of non-carious cervical lesions (NCCLs). material and method: a search of the literature was carried out up to january 2018, in the biomedical databases: Pubmed, Embase, Scielo, Science Direct, SIGLE, LILACS, BBO, Google Scholar and the Central Register of Cochrane Clinical Trials. the selection criteria of the studies were as: randomized clinical trials, with a maximum age of 5 years and which report the clinical effects (marginal adaptation, discoloration or marginal staining, presence of secondary caries, postoperative sensitivity, retention and fractures) of the UA in the treatment of NCCLs. the risk of study bias was analyzed through the Cochrane Handbook of systematic reviews of interventions. results: the search strategy resulted in eight articles that reported no difference in marginal adaptation, discoloration or marginal staining, presence of secondary caries and postoperative sensitivity among the adhesive strategies of the UA; however they reported a difference between the retention and the presence of fractures, with the conventional adhesive strategy resulting in a better clinical effect. conclusion: the reviewed literature suggests that the conventional adhesive strategy of UAs results in greater retention and absence of fractures in the treatment of NCCLs.

Las restauraciones directas con resina compuesta realizadas en nuestros pacientes requieren mucha pericia por parte del operador, y a pesar que, a pesar que en muchos de los casos cumplimos con los protocolos adhesivos requeridos y la inserción correcta del material en la preparación; sin embargo, luego de realizar todo el proceso restaurador, dedicamos muy poco tiempo al acabado y pulido siendo este paso fundamental para lograr el éxito. Muchos no logramos obtener resultados satisfactorios al utilizar un sistema de acabado y pulido porque no sabemos utilizarlo adecuadamente, no sabemos cuánto tiempo dura el proceso, cual es la secuencia correcta o que aislante térmico utilizar. En el presente artículo se detalla la resolución de un caso clínico a través de un método de acabado y pulido de restauraciones directas sobre resina compuesta en el sector anterior. Los resultados obtenidos fueron satisfactorios ya que se pudo mejorar las restauraciones devolviendo la naturalidad, estética y función perdida preservando la vitalidad pulpar a través de protocolos conservadores. Concluimos, que el proceso de acabado y pulido de las restauraciones con resina compuesta es fundamental para garantizar el éxito del tratamiento, debemos de conocer a cabalidad el sistema de pulido para no injuriar la pulpa dental y así no perjudicar su vitalidad...
Direct composite resin restorations performed in our patients require much expertise by the operator and in many cases we comply with the required adhesive protocols and the correct inclusion of the material in the preparation, but after the restorative process we dedicate very little time to the finishing touch and polish this being a fundamental step for success. Many fail to obtain satisfactory results by using a system of finishing and polishing because we donÆt use it properly, do not know how long the process takes, or which is the correct sequence or insulation to use. This article details the resolution of a clinical case through a method of finishing and polishing of restorations on direct composite resin in the anterior teeth. The results obtained were satisfactory since they failed to improve restorations returning natural, aesthetic and lost function preserving the vitality pulp through conservative protocols. We conclude that the process of finishing and polishing our composite resin restorations was crucial to ensure the success of our treatments, but we must know perfectly and adequately the system used so as not to injure the dental pulp and thus not jeopardize its vitality...

Con la técnica del poste anatómico se logra copiar la morfología interna del conducto radicular utilizando resina compuesta sobre un poste de fibra de vidrio, de esta manera se logra reducir el espesor del cemento mejorando su adaptación y, por consiguiente, mejor retención En el artículo se registra la confección de un poste anatómico en la resolución de un caso clínico en una pieza dentaria anteroinferior. Los resultados fueron satisfactorios para el paciente ya que se logró restaurar la pieza dentaria para la futura confección de una prótesis parcial fija. Conclusiones: Los postes de fibra de vidrio carecen de un factor fundamental que es el no seguir la morfología interna del conducto radicular y esto trae como consecuencia una mayor cantidad del agente cementante a ese nivel, por consiguiente, mayor riesgo en formación de burbujas o vacíos que pueden afectar la retención y estabilidad del poste...
With the technology of the anatomical post it is achieved to copy the internal morphology of the root canal using composite resin on a post of glass fiber, hereby it is achieved to reduce the thickness of the cement improving the adjustment of the same one and consequently better retention. In this article the confection of an anatomical post in the resolution of a clinical case in a front inferior dental piece is registered. The results were satisfactory for the patient since it was achieved to restore the dental piece for the future confection of a partial fixed prothesis. The posts of glass fiber lack a fundamental factor that is not to follow the internal morphology of the root canal and this brings as consequence a major quantity of the cementing agent to this level, consequently major risk in formation of bubbles or emptinesses that can affect the retention and stability of the post...
