Microleakage of Accelerated Mineral Trioxide Aggregate and Portland Cement in an In Vitro Apexification Model

A Comparative Study of Using a Combination of Calcium Chloride and Mineral Trioxide Aggregate as the Pulp-capping Agent on Dogs’ Teeth

“…Poor handling characteristics are one of the main drawbacks of MTA (5), for which numerous investigations have been conducted (2,(5)(6)(7)(8)(9)(10)(11)(12). Several investigations have used additives for improving the handling characteristics of MTA (2,(5)(6)(7)(8)(9)(10)(11)(12).…”

“…Several investigations have used additives for improving the handling characteristics of MTA (2,(5)(6)(7)(8)(9)(10)(11)(12). These studies were mainly in vitro and have not covered all of the physical properties of the material; therefore, the relative clinical applications of MTA have remained unclear (2,5,6).…”

“…There are several in vitro and a few in vivo investigations that have indicated that the addition of CaCl 2 to MTA improved its handling characteristics and calcium ion release, while not affecting its biocompatibility (7)(8)(9)(10)(11)(12)(13)(14). A preliminary investigation on dogs' teeth has provided encouraging results regarding the use of MTA/CaCl 2 as a pulpotomy agent (15) although statistical analysis was not performed because as it was a descriptive study.…”

Effects of a Novel Hydration Accelerant on the Biological and Mechanical Properties of White Mineral Trioxide Aggregate

“…Many have attempted to shorten the setting time of hydrated MTA by introducing astrong calcium-based electrolyteso it completely dissociates in solution to produce calcium ions to accelerate the dissolution step. The setting of MTA is significantly accelerated by highly soluble calcium compounds (ie, calcium chloride, calcium nitrate, or calcium formate) (13)(14)(15). One of the most important features of MTA is the antimicrobial properties of its hydration byproduct, CH (16,17).…”

Effect of Additives on Mineral Trioxide Aggregate Setting Reaction Product Formation

“…6 To improve MTA's setting time, many investigations have described MTA preparations with various additives. [12][13][14][15][16][17][18][19][20][21][22][23][24][25] Commendably, many of these studies also examined if the additives had effects on various physical properties. Although they indicated further studies were required, 1 study cautiously recommended using either 5% calcium chloride (CaCl2) or sodium hypochlorite (NaOCl) gel in place of water when mixing MTA to be used in single-visit endodontic procedures.…”
