RESUMOO objetivo deste estudo foi encontrar, através de uma revisão de literatura, o meio mais adequado para o armazenamento de dentes avulsionados. Esse meio deve preservar a vitalidade, aderência e a capacidade clonogênica das células do ligamento periodontal. Os meios selecionados para essa revisão de literatura foram: solução salina balanceada de Hank (HBSS), própolis, água de coco, leite, chá verde, água de torneira, clara de ovo, saliva, Gatorade, amora, ViaSpan, chá verde, água de coco, extrato de amora, própolis e clara de ovo apresentaram bons resultados nos estudos selecionados, porém necessitam mais estudos que comprovem sua eficácia. HBSS e ViaSpan tiveram os melhores resultados, apresentando grande potencial de manter as células do ligamento periodontal viáveis após a avulsão. O leite demonstrou resultados satisfatórios, boas propriedades, baixo custo e fácil disponibilidade à população, sendo este o meio ideal para armazenamento de dentes avulsionados, quando HBSS e ViaSpan forem indisponíveis. Descritores ABSTRACTThe aim of this study was to find, through a literature review, the most appropriate means for storage of avulsed teeth. Such means shall preserve the vitality, adherence and clonogenic capacity of cells of the periodontal ligament. The selected means for this literature review were: Hank's balanced salt solution (HBSS), propolis, coconut water, milk, green tea, tap water, egg white, saliva, Gatorade, blackberry, ViaSpan. green tea, coconut water, mulberry extract, propolis and egg white showed good results in selected studies, but need more studies to prove its effectiveness. HBSS and ViaSpan had the best results, presenting great potential to maintain the cells in viable periodontal ligament after avulsion. The milk was satisfactory, good properties, low cost and easy availability to the population, which is the ideal medium for storage of avulsed teeth when HBSS and ViaSpan are unavailable.

The adhesive systems are responsible for an efficient union between teeth and resin, resulting in a longevity restoration. They are organic molecules di or multifunctional that contain reactive groups that interact with dentin and with the resin monomer of composite resin. The adhesive systems are characterized by wet adhesion, which is a result of presence of hidrophylics radicals in their compositions, to promote a better bond and the best properties of the adhesion. Adhesive systems may use two different strategies to interact with the dental structure: total-etching and self-etching technique. The total-etching systems require a conditioning, a rinsing and a priming step in order to allow involvement of collagen fibers by the resin monomers and the formation of the so-called 'hybrid layer'. The total-etching promotes the cleaning of dentin, also promotes superficial demineralization and delivers collagen fibrils to participate of an interface union mechanism teeth/ adhesive system/restorative material. Self-etching adhesive systems are characterized by demineralization and infiltration of resin monomers simultaneously. This technique is attractive because reduced sensitivity associated with retaining the smear layer and smear plugs, thereby, minimize the possibility of inadvertent contamination of the bonding surface with dentinal surface through dentinal fluid transudate.
