“…As the hydration rate of dicalcium silicate is lower than that of tricalcium silicate 18 , the compressive force 14 of MTA reaches its maximum several days after mixing 19 . Various factors may influence the compressive force of MTA, including type of MTA, liquid that is mixed with the material, condensation pressure on the material, pH value of the mixed liquid, and MTA storage condition 16,[20][21][22] . Shabahang et al 23 studied MTA for apexification and concluded that placing an apical MTA cap is a promising alternative to conventional therapy with calcium hydroxide.…”

Apexification is the endodontic procedure performed in order to induce the formation of a physical barrier of mineralized tissue in teeth with RESUMOA apicificação é o procedimento endodôntico realizado para induzir a formação de uma barreira física de tecido mineralizado em dentes com incompleta formação radicular. É realizada, principalmente, quando, por alguma razão, ocorre necrose pulpar em dentes com rizogênese incompleta e, também, nos casos em que o forame se encontra aberto, em função de reabsorção radicular. Nessas situações, o tratamento endodôntico convencional se torna difícil ou quase impossível, por causa do amplo forame. O procedimento de apicificação, nesses casos, é geralmente realizado por meio de trocas sucessivas de curativos de hidróxido de cálcio, com o objetivo de induzir a formação de uma barreira física de tecido mineralizado, possibilitando, então, a obturação dos canais radiculares. O protocolo apresentado neste artigo, bem como os casos clínicos relatados, ilustram uma opção de tratamento mais rápido, realizado em três sessões, utilizando um tampão ou plug de MTA, material que oferece boas propriedades biológicas e físicas.Termos de indexação: Apexificação. Hidróxido de cálcio. Tratamento do canal radicular.

In recent years, a new endodontic cement, calcium enriched mixture (CEM) has been introduced; with clinical applications similar to those of mineral trioxide aggregate (MTA). It has been shown that CEM has higher antibacterial activity than MTA. On the other hand, use of chlorhexidine (CHX) to promote the antibacterial activity of different dental materials is increasing. The aim of the present study was to evaluate the effect of adding CHX to CEM on its antibacterial activity. The antibacterial activities of the materials under study [(CEM cement + CEM solution + 2%CHX) and (CEM cement + CEM solution)] against Pseudomonas aeroginosa, Enterococcus faecalis, Staphylococcus aureus and Escherichia coli were evaluated using agar diffusion technique, followed by determination of the diameter of microbial zone of inhibition around the materials by three independent observers after 72 h. Data were analyzed by Mann-Whitney U test. Statistical significance was defined at P<0.05. The mean diameters of zones of inhibition in the CEM + CEM liquid and CEM + CEM liquid + CHX groups against P. aeroginosa, E. faecalis, S. aureus and E. coli were (13.2 and 9), (21.10 and 6), (20.2 and 9) and (17 and 9.75) ml, respectively, with larger diameters in the CEM + CEM solution + CHX group as compared to CEM + CEM solution group with all the microorganisms (P<0.05). Incorporation of CHX with CEM resulted in an increase in antimicrobial activity of CEM.

“…Since Mineral Trioxide Aggregate (MTA) is used in dentistry, several studies evaluated the effect of MTA on microorganisms [1][2][3][4][5][6] , with conflicting results. Torabinejad et al 7) found that MTA was effective against facultative microorganism but not against other bacterial strains, including Enterococcus faecalis.…”

The purpose of this study was to evaluate some physical and chemical properties of MTA incorporated with antibacterial silver zeolite (SZ). 0%, 0.2% or 2% mass fraction of SZ was added to MTA powder. The amounts of calcium released from the specimen in deionized water were measured with an atomic absorption spectrophotometer. The setting times of the samples were evaluated using Gilmore-type needles. For solubility and water absorption tests, the samples were placed in a cylindrical polystyrene-sealed container. At 7 days, the samples were removed from solutions and blotted dry for solubility and water absorption test. The highest calcium release was detected in 2% SZ MTA at 24 h. The addition of 2% SZ to MTA reduced the setting time statistically (p<0.05). 2% SZ MTA was significantly more soluble than MTA and 0.2 % SZ MTA (p<0.05). Further research is needed prior to clinical use of MTA with incorporated SZ.
