Cimentos endodônticos: análise morfológica imediata e após seis meses utilizando microscopia de força atômica

Abstract: O objetivo deste trabalho foi analisar a morfologia dos cimentos Sealapex, Apexit, Sealer 26 (cimentos a base de hidróxido de cálcio) e Ketac Endo (cimento de ionômero de vidro), através da microscopia de força atômica, verificando-se as características de suas partículas após a obturação dos canais radiculares e após um período de seis meses de contato com o plasma sanguíneo humano. Utilizaram-se 16 dentes unirradiculares humanos extraídos e incluídos em blocos de resina após o preparo biomecânico. As raízes … Show more

“…Particularmente, o cimento Sealer 26 ® é constituído de um sistema resina (epóxi bisfenol) e pó (trióxido de bismuto, hidróxido de cálcio, hexametilenotetramina e dióxido de titânio) e tem demonstrado radiopacidade inferior ao AH Plus ® e ao cimento Endofill ® [5]. Para compensar o inconveniente, de modo aleatório muitos clínicos incorporam iodofórmio ao pó do Sealer 26 ® , e tal conduta não ocasiona alterações no comportamento físico-químico e biológico de materiais como o cimento Portland [7] ou Sealapex [6,12].…”

“…Endodontic treatment aims to restore the normality of lost apical and periapical tissues 46,47 by means of not only deeply cleaning and disinfecting the root canal system so as to control pathogenic microorganisms, Inluence of hypertension on oral infections and endodontic treatment [ original article ] but also through complete three-dimensional sealing of the root canal with filling materials that present adequate physical and biological properties for tissue repair, by means of inducing mineralization. [48][49][50] Some materials used in endodontic treatment function as anti-inflammatory and antibacterial drugs, as well as inducers of osteogenesis and cementogenesis. [48][49][50][51][52] Calcium hydroxide is widely used during endodontic treatment, given that it eliminates bacteria and their toxins, has an anti-inflammatory action, neutralizes acid products and activates alkaline phosphatase.…”

“…Several studies have addressed different aspects of the properties and characteristics of sealers such as their granularity (Caicedo & von Fraunhofer 1988, Valera et al. 2000), the dimensional changes they undergo after setting (Wiener & Schilder 1971, Kazemi et al.…”
