ABSTRACT
Introducción: las lesiones cervicales no cariosas (NCCL, por sus siglas en inglés) son un grupo de lesiones que afectan el área cervical del órgano dental causando hipersensibilidad dentinaria y defectos estéticos. Objetivo: analizar la literatura sobre las lesiones cervicales no cariosas, su etiología, consideraciones anatómicas, características morfológicas de la lesión y tratamientos no restaurativos. Material y métodos: se realizó una búsqueda en la base de datos PubMed, utilizando las palabras clave: non-carious cervical lesions OR noncarious cervical lesions OR tooth wear OR tooth erosion OR dental abfraction OR abfraction, recopilando un total de 78 artículos. Resultados: es necesario determinar la etiología antes de seleccionar las estrategias de tratamiento para las lesiones cervicales no cariosas. Conocer los distintos tipos de tejidos que componen al órgano dentario facilita la comprensión de los factores que participan en el desarrollo de las lesiones cervicales no cariosas. Esto permite que el tratamiento se enfoque más en la causa del problema que en los síntomas. Con esto podemos modificar diversos factores de manera interceptiva, los tratamientos de terapia con láser y compuestos tópicos son una estrategia mínimamente invasiva. Conclusiones: la mejor manera de describir a las lesiones cervicales no cariosas sería como una enfermedad multifactorial. Se debe prestar especial atención en los métodos de diagnóstico, identificando cofactores que propicien el avance de la lesión, como son la fricción y la biocorrosión. Esta revisión brinda datos que asocian a los factores oclusales como una de las principales causas de una enfermedad que afecta a más de la mitad de la población adulta (AU)
Introduction: non-carious cervical lesions (NCCL) are a group of lesions that affect the cervical area of the dental organ causing dentin hypersensitivity and cosmetic defects. Objective: to know, through a systematic review, the current state of non-carious cervical lesions. Material and methods: a search was conducted in the PubMed database, using the keywords: non-carious cervical lesions OR noncarious cervical lesions OR tooth wear OR tooth erosion OR dental abfraction OR abfraction, compiling a total of 78 articles. Results: determining etiology is necessary before selecting treatment strategies for non-carious cervical lesions (NCCL). Know the different types of tissues that make up the dentary organ, facilitate the understanding of the factors involved in the development of noncarious al cervical lesions. This allows treatment to focus more on the cause of the problem than on symptoms. With this we can modify various factors in an interceptive way, laser therapy treatments and topical compounds, are a minimally invasive strategy. Conclusions: the best way to describe non-carious al cervical lesions would be as a multifactorial disease to which special attention should be paid to both diagnostic methods, identifying cofactors that promote the progression of injury, such as friction and biocorrosion. This review provides data that associates occlusal factors as one of the main causes of a disease that affects more than half of the adult population (AU)

Este artigo analisa as respostas das religiões afro-brasileiras à epidemia de Aids no Recife, considerando a estrutura simbólica religiosa. Baseando-se em observações participantes e em entrevistas em profundidade realizadas com líderes religiosos afro-brasileiros e técnicos de saúde pública e de ONG, destaca a importância do "axé", a categoria nativa utilizada para pensar os eventos corporais, para entender a história da Aids nessa comunidade religiosa. Axé é energia mística, vitalidade corporal. Ele é manipulado em rituais religiosos e simbolicamente associado a sangue, suor e sêmen. Nos tempos de HIV, os rituais de escarificação corporais e a troca de fluidos durante as transações sexuais, formas para a circulação do axé e elementos-chave para o cultivo deste, também se tornam meio para a transmissão do HIV. Esses elementos foram o foco do diálogo entre as instituições religiosas e o sistema de saúde pública, um processo que gerou mudanças nas práticas religiosas de regulação da reprodução social e da vida sexual dos adeptos.
This article analyzes the responses of Afro-Brazilian religions to the Aids epidemic in Recife, taking into consideration the religious symbolic structure. Drawing on participant observation and in-depth interviews conducted with Afro-Brazilian religious leaders and public health officials, it highlights the importance of "axé" _ the native category used to interpret corporal events _ in order to understand the history of Aids in this religious community. Axé is mystical energy, corporal vitality. It is manipulated in religious rituals and is symbolically associated with blood, perspiration and semen. In these times of HIV, the body scarification rituals and exchanges of fluids during sexual exchanges are the ways by which axé circulates among adept and are the core elements for its promotion, though they have also become a means for the transmission of the HIV virus. These elements were the basis of the dialogue between religious institutions and the public health system. This process generated changes in religious practices for regulation of social reproduction and the sexual life of the adepts.
