Evaluation of the Tissue Response to MTA and MBPC: Microscopic Analysis of Implants in Alveolar Bone of Rats

“…Degrood et al (38) in 1995, observed, in the control group, on the 90th day, bone tissue inside the polyethylene tube; however, in the present study, the 30th day timeframe was used as the longest period of observation and, at that time, the healing was still not completely established as evidenced by the presence of an inflammatory infiltrate. This data suggests that a longer period of observation could be employed to observe the best properties of these materials in the methodology used.…”

“…Extraction sockets became lined by periodontal ligament, which makes it possible to study the healing process by evaluation of the clot, and the ligament periodontal organization (38,41,42). Polyethylene tubes implanted in the dental extraction socket had similar behavior to that reported by Torneck (34), who implanted the tubes in subcutaneous tissue of rats, and already observed tissue growth.…”

“…Different methods are used to evaluate the biocompatibility of the endodontic materials (32)(33)(34)(35)(36)(37)(38)(39)(40); however, the dental alveolar implantation method must be emphasized because of the potential of differentiating the phases of bone healing (37). Extraction sockets became lined by periodontal ligament, which makes it possible to study the healing process by evaluation of the clot, and the ligament periodontal organization (38,41,42).…”

Evaluation of Rat Alveolar Bone Response to Angelus MTA or Experimental Light-cured Mineral Trioxide Aggregate Using Fluorochromes

“…The dental alveolar implantation method is clinically relevant because of the potential to differentiate the phases of bone healing (6,21) and the tissue response after endodontic treatment or apical surgery (6). Conventionally, the tissue response has been histologically evaluated using the paraffin embedding and hematoxylin and eosin staining.…”

Mixing failures of endodontic sealers: an in vivo biocompatibility study

“…The study of dental materials biocompatibility in Wistar rats was performed because previous investigations [12,27] have indicated that alveolar implant-a simple insertion technique that simulates the reactions of the apical tissue area-closely models the endodontic clinical condition [28]. However, the authors of these previous reports stated that any material introduced into the extraction socket disturbed tissue organization and injured the periodontal ligament, leading to delays in the normal repair process [23,29].…”
