O Cimento de Óxido de Zinco e Eugenol (OZE) tem sido comumente utilizado como material obturador de canais radiculares na dentição decídua, sendo o pioneiro em sua categoria, mesmo não cumprindo todos os requisitos ideais de um bom material obturador. Possui propriedades anti-inflamatórias, analgésicas e ação antimicrobiana, que reforçam a indicação de seu uso. Entretanto, sua reabsorção é mais lenta do que a de outros materiais, podendo irritar os tecidos periapicais e desviar o trajeto de erupção do dente sucessor. O objetivo deste trabalho é apontar as vantagens e desvantagens do uso de OZE para obturação de canais radiculares de dentes decíduos. Realizou-se, assim, uma revisão de literatura na base de dados PubMed, utilizando as seguintes palavras-chave combinadas entre si: “pulpectomy” “tooth deciduous”, e “zinc oxide-eugenol cement”. Foram obtidos 44 artigos entre 2006 e 2016, dos quais 11 foram selecionados, utilizando-se como critérios de inclusão casos clínicos, estudos in vivo e revisões de literatura sobre o uso de OZE para pulpectomia em dentes decíduos e como critérios de exclusão estudos que não possuíam grupo controle e que não apresentaram resultados conclusivos. Observou-se vantagens no uso do OZE como pasta endodôntica devido a sua ação analgésica e anti-inflamatória, e que, apesar das suas desvantagens, promove certa eficácia nos casos de pulpectomia quando comparada a outras pastas menos acessíveis.Palavras-chave: Pulpectomy.

Under both in vitro and in vivo conditions, bases of zinc oxide-eugenol, calcium hydroxide, and zinc phosphate cement reduced the rate of thermal diffusion through amalgam restorations. Thermal diffusion was slowest in the presence of zinc oxide-eugenol bases, followed by calcium hydroxide and zinc phosphate cement. However, the clinical significance of the differences is not known.

To determine the in vivo effects of a zinc oxide-eugenol mixture (ZOE) on the cyclo-oxygenase system in dental pulp, we used radioimmunoassay to measure the levels of prostaglandin E2 (PGE2), 13,14-dihydro-15-keto-PG (DHK-PG), thromboxane B2 (TXB2), and 6-keto-PGF1α in the dental pulp of rats. When the dental pulp was irritated by a hole made in the dentin of the mandibular incisors without use of any coolants, the levels of these cyclo-oxygenase products in the pulp were increased to, respectively, 2.8, 1.7, 10.0, and 2.6 times those in the normal pulp at six hr after treatment. In contrast, these increases in cyclo-oxygenase products disappeared immediately when the artificial cavity in the dentin was filled with ZOE (P/L; 1 g/0.25 mL), but were not altered when the cavity was filled with zinc oxide-water (ZOW, 1 g/1.5 mL). Most of the eugenol portion of ZOE was released into the pulp within two hr after the cavity was filled with ZOE. The maximal eugenol content was 35 pmol per mg of pulp. Furthermore, when the cavity was filled either with ZOE or by the addition of 10 μmol/L eugenol to the pulp homogenate, biosynthesis of 14C-6-keto-PGF1α, PGF2α, and PGE 2 from 14C-arachidonic acid in the homogenate was inhibited. These results suggest that eugenol released from ZOE in the cavity prepared in the dentin inhibited the biosynthesis of cyclo-oxygenase products during pulp irritation.

Simultaneous water and ethanol-based synthesis and coating of copper and zinc oxide (CuO/ZnO) nanoparticles (NPs) on bandages was carried out by ultrasound irradiation. High resolution-transmission electron microscopy demonstrated the effects of the solvent on the particle size and shape of metal oxide NPs. An antibacterial activity study of metal-oxide-coated bandages was carried out against Staphylococcus aureus (Gram-positive) and Escherichia coli (Gram-negative). CuO NP-coated bandages made from both water and ethanol demonstrated complete killing of S. aureus and E. coli bacteria within 30 min., whereas ZnO NP-coated bandages demonstrated five-log reductions in viability for both kinds of bacteria after 60 min of interaction. Further, the antibacterial mechanism of CuO/ZnO NP-coated bandages is proposed here based on electron spin resonance studies. Nanotoxicology investigations were conducted via in vivo examinations of the effect of the metal-oxide bandages on frog embryos (teratogenesis assay—Xenopus). The results show that water-based coatings resulted in lesser impacts on embryo development than the ethanol-based ones. These bandages should therefore be considered safer than the ethanol-based ones. The comparison between the toxicity of the metal oxide NPs prepared in water and ethanol is of great importance, because water will replace ethanol for bulk scale synthesis of metal oxide NPs in commercial companies to avoid further ignition problems. The novelty and importance of this manuscript is avoiding the ethanol in the typical water:ethanol mixture as the solvent for the preparation of metal oxide NPs. Ethanol is ignitable, and commercial companies are trying the evade its use. This is especially important these days, as the face mask produced by sonochemistry (SONOMASK) is being sold all over the world by SONOVIA, and it is coated with ZnO.
