“…Coronal microbial leakage could cause reinfection of the pulp cavity 31) , so the sealing ability of the capping material is essential for the clinical success of vital pulp therapy. It appears that MTA provides good sealing ability and marginal adaptation 32) .…”

The aim of this study was to compare the biocompatibility of Endocem Zr ® and ProRoot MTA ® by histopathologic analysis in a canine model of pulpotomy. This study utilized 39 teeth of two beagle dogs. The exposed pulp tissues were treated by pulpotomy using ProRoot MTA (n=19) or Endocem Zr (n=20). After 8 weeks, the teeth were extracted and processed with hematoxylin-eosin staining for histologic evaluation. Most of the specimens in both groups developed a calcific barrier at the pulp amputation site and formed an odontoblast layer. However, some of the Endocem Zr specimens showed less calcific barrier formation with a greater inflammatory response and less odontoblast layer formation when compared with the ProRoot MTA specimens. ProRoot MTA and Endocem Zr specimens developed a calcific barrier; however, ProRoot MTA was more biocompatible than Endocem Zr.

“…Causes of failure include: incomplete obturation, root perforation, external root resorption, coexistent periodontal-periradicular lesions, grossly overfilled or overextended canals, canals left unfilled, developing apical cysts, adjacent pulpless teeth, inadvertently removed silver points, broken instruments, unfilled accessory canals, constant trauma, and nasal floor perforation (1). Recent literature has additionally suggested coronal leakage of bacteria or endotoxin as potential causes of endodontic treatment failure (3)(4)(5). The clinical significance of this leakage is debatable (6 -8).…”

A prospective in vivo investigation was conducted to determine radiographic and clinical factors associated with contemporary nonsurgical endodontic retreatments. Approximately 1100 failing endodontically treated teeth were screened to determine an appropriate treatment plan. Using magnification, 337 consecutive retreatment cases were evaluated and treated. The vast majority of the retreated cases involved multiple factors. Eighty-five percent of the cases presented with periradicular radiolucencies. Sixty-five percent of the cases demonstrated poor radiographic obturation quality. Associated pain was noted 51% of the time. Forty-two percent of the teeth had untreated canal space. It was statistically significant (Chisquare, p < 0.05) that additional canal space was located and treated in 89% of the cases that had previous radiographic asymmetrical obturations. Evidence of coronal leakage was noted in 13% of the retreated teeth. Tooth number, obturation materials, overfills, and previous surgical retrofillings were also recorded. Recommendations were made that might improve the rate of clinical success.

“…For the last century, gutta-percha in combination with a sealer has been used as the primary root canal-filling material, owing to advantages such as adequate obturation of the root canal space, favorable handling characteristics, and biocompatibility 1) . However, when gutta-percha canal fillings were tested in vitro by using models of dye penetration, fluid filtration, or bacterial leakage [2][3][4][5] , some vulnerability was observed, especially with regard to coronal microleakage.…”

“…A quantitative analysis by micro-CT was utilized in the present study to locate and calculate the voids after canal filling. Therefore, the aims of this study were as follows: (1) to evaluate and compare the percentage of voids in 5 mm apical canals filled by MTA with those filled by gutta-percha/AH plus sealer, (2) to separately compare the percentage of voids in mesial and distal canals depending on the filling materials, and (3) to investigate the differences in the percentage of voids between mesial and distal canals.…”

Comparison of root canal filling quality by mineral trioxide aggregate and gutta percha cones/AH plus sealer

The aims of this study were to evaluate the quality of canal filling using mineral trioxide aggregate (MTA) and gutta-percha (GP) in root canals, and to investigate the differences in the percentage of voids between mesial and distal canals by using microcomputed tomography. Twenty-two extracted human mandibular molars were instrumented using rotary files. Two teeth without canal fillings served as negative controls, and the other teeth were obturated with either ProRoot ® MTA or gutta-percha and AH Plus ® sealer. Obturated teeth were scanned with microcomputed tomography, and the percentage of voids (V %) was calculated. These specimens were also examined under a scanning electron microscope. The MTA group showed a significantly higher V % than the GP groups (p<0.05). The mesial canal groups showed significantly higher V% than did the distal canal groups (p<0.05). In orthograde filling, MTA exhibited significantly lower filling quality than did GP.
