Antimicrobial Activity of Gel-Entrapped Catechins toward Oral Microorganisms

Antibacterial Efficacy of Epigallocatechin-3-gallate against Streptococcus mutans: A Systematic Review / Eficacia antibacteriana de la epigalocatequina-3-galato contra el Streptococcus mutans: Revisión Sistemática

“…e results of the comparison between CHX and EGCG showed that both substances were effective in inhibiting microbial the growth and biolm formation. Other studies [26,27,28,29,30,31] used as negative control the absence of EGCG and in these situations; it was observed that there was a marked growth of microorganisms compared to the experimental group. One study compared the antimicrobial activity of EGCG whit black, oolong and Pu-erh tea against growth of S. mutans [32] and another study had no control group [33].…”

“…CHX presents antimicrobial efficacy in vitro and in vivo (mouthwash) against salivary microbiota cariogenic and has a role in preventing the development of gingivitis [22]. Some studies compared EGCG with CHX [17,23,24,25,26]. e results of the comparison between CHX and EGCG showed that both substances were effective in inhibiting microbial the growth and biolm formation.…”

“…In addition, different forms of manipulation of the EGCG, in some studies the solution was used [29,30,31], others incorporated into dental materials [24,27,28], and even as specic formula [26]. Despite all these variety in the method and material handling, the results suggested that it is a stable substance and with antimicrobial properties and able to inactivate the S. mutans, and thus inhibit the formation of biolm.…”

Exploring the possible applications of catechin (gel) for oral care of the elderly and disabled individuals

“…Therefore, it is essential that the microbial count present in the oral cavity be strictly controlled to suppress serious diseases progression [41,42].…”

Formulação à base de Epigalocatequina-3-galato, derivada do chá verde, desenvolvida para uso endodôntico: estudo físico-químico e biológico

“…Estudos mostram que essa substância desempenha efeito anticariogênico decorrente de sua efetiva ação antimicrobiana contra S. mutans e S. sobrinus (Sakanaka et al, 1989;Yoshino et al, 1996;Ferrazzano et al, 2011;Tamura et al, 2011;Xu et al, 2012;Shumi et al, 2014;Anita et al, 2015;Sarin et al, 2015), por impedir a aderência bacteriana ao dente por meio da inibição da enzima glicosiltransferase e da amilase bacteriana (Hamilton-Miller, 2001;Subramaniam et al, 2012;Jung et al, 2012;Cai et al, 2013). Devido à sua comprovada eficácia contra os micro-organismos e na inibição de metaloproteinases, esse extrato tem sido incorporado em materiais odontológicos, tais como, adesivos dentinários (Du et al, 2012), resinas compostas Mankovskaia et al, 2013) e cimentos de ionômero de vidro (Hu et al, 2013).…”
