Portland cement versus MTA as a root-end filling material. A pilot study

Abstract

PURPOSE:To assess periradicular lesions clinically and by computed tomography (CT) after endodontic surgery using either Portland cement or mineral trioxide aggregate (MTA) as a root-end filling material. METHODS:Three patients diagnosed with periradicular lesions by cone-beam CT underwent endodontic surgery with root-end filling.Patient A was treated with MTA as the root-end filling material, patient B was treated with Portland cement and patient C had two teeth treated, one with MTA and the other with Portland cement. Six months after surgery, the patients were assessed clinically and by CT scan and the obtained results were compared. RESULTS:Periradicular tissue regeneration was observed in all cases, with no significant differences in bone formation when comparing the use of MTA and Portland cement as root-end filling materials. CONCLUSION:Both mineral trioxide aggregate and Portland cement were successful in the treatment of periradicular lesions.

The use of a biocompatible cement in endodontic surgery. A randomized clinical trial 1

“…The present study was conducted with a sample larger than that of the previous pilot study and the use of both cements as root-end filling materials resulted in significant periradicular tissue regeneration, consistent with other studies 13,16,20,23 .…”

“…The lesions were diagnosed using cone-beam computed tomography (cone-beam CT; Model i-CAT 17-19, Imaging Sciences International LLC, Hatfield, PA, USA) 23,26,27 . The dimensions of the long axes of the lesions in the buccopalatal and coronal-apical directions were measured using CT images analyzed with the Dental Slice virtual navigation software (Bioparts Prototipagem Biomédica, Brasilia, DF, Brazil).…”

“…Pozzolana Biologic Silva cement (PBS ® ) is a biocompatible medical Portland cement that contains pozzolana and calcium carbonate as additives, which confer compressive strength to the material 23 . PBS was developed as part of a doctoral dissertation (J.D.S.N.)…”

“…909673667) in July 2015 and the medical cement is currently in the industrialization phase. A pilot clinical study 23 was conducted comparing the WSPCA (later called PBS cement) with MTA-Angelus ® as a root-end filling materials in endodontic surgery; serving as basis for this study with a larger sample. Because it is essential that root-filling materials resist masticatory forces 24,25 , PBS may be an alternative to MTA in endodontic surgery.…”

Bioceramic cement in the filling of bone defects in rats

“…Recent studies have allowed the development of biological cement (PBS ® CIMMO rapid set) with the addition of additives (natural elements responsible for the increase of cement strength as well as the setting time) and without radioactivity 12 . The experimental and clinical studies that culminated in the development of PBS ® CIMMO rapid set were designed for installation in crowns and dental root structures in situations called unconventional, because no protocols had been developed for these applications, and the roots were condemned [10][11][12][13][14]23 . However, recently, a study was carried out using PBS ® CIMMO cement in a successful endodontic retreatment of alveolar abscesses 11 .…”
