Objective The aim of this study was to evaluate the marginal adaptation of Biodentine in comparison with Mineral Trioxide Aggregate ( MTA ) and Intermediate Restorative Material ( IRM ) , as a root end filling material , using Scanning Electron Microscopy ( SEM ) . Material s and Methods : Thirty permanent maxillary central incisors were chemo-mechanically prepared and obturated . Three millimetres of the root end were resected and 3 mm retro cavity preparation was done using ultrasonic retrotips . The sample s were r and omly divided into three groups ( n=10 ) and were restored with root end filling material s : Group I – MTA , Group II – Biodentine , Group III – IRM . The root ends were sectioned transversely at 1 mm and 2 mm levels and evaluated for marginal adaptation using SEM . The gap between dentin and retro filling material was measured at four quadrants . The mean gap at 1 mm level and 2 mm level from the resected root tip and combined mean were calculated . The data were statistically analyzed , using one-way ANOVA and Tukey ’s HSD post hoc test for intergroup analysis and paired t-test for intragroup analysis . Results : The overall results showed no statistically significant difference between MTA and IRM but both were superior when compared to Biodentine . At 1 mm level there was no statistically significant difference among any of the tested material s. At 2 mm level MTA was superior to both IRM and Biodentine . Conclusion : In overall comparison , MTA and IRM were significantly superior when compared to Biodentine in terms of marginal adaptation , when used as retro grade filling material The purpose of this study was to compare the ability of different thicknesses of mineral trioxide aggregate ( MTA ) to prevent apical leakage through the use of a protein-dye complex with Coomassie Brilliant Blue G. Sixty-four teeth were divided into 4 groups , then filled with MTA to depths of 1 , 2 , 3 , or 4 mm . Two teeth served as the positive controls . Another 2 teeth served as the negative controls . Root-filled teeth were mounted in an apparatus and then challenged with protein solution . The evaluation was conduced at 24-hour intervals for 60 days . The 1-mm-thick MTA was the least effective in preventing apical leakage ( P < .05 ) . No significance difference was found between 2- and 3-mm-thick MTA ( P > .05 ) . Four-millimeter-thick MTA was significantly more effective than the other thicknesses tested ( P < .05 ) . The results of this study suggest that the thickness of 4 mm is most adequate for the use of MTA as a root-end filling material Context : Where nonsurgical endodontic intervention is not possible , or it will not solve the problem , surgical endodontic treatment must be considered . A major cause of surgical endodontic failures is an inadequate apical seal , so the use of the suitable substance as root-end filling material that prevents egress of potential contaminants into periapical tissue is very critical . Aims : The aim of the present ex-vivo study was to compare and evaluate the three root-end filling material s of mineral trioxide aggregate ( MTA ) family ( white MTA [ WMTA ] , grey MTA [ GMTA ] and Portl and cement [ PC ] ) for their marginal adaptation at the root-end dentinal wall using scanning electron microscopy ( SEM ) . Material s and Methods : Sixty human single-rooted teeth were decoronated , instrumented , and obturated with Gutta-percha .  After the root-end resection and apical cavity preparation , the teeth were r and omly divided into three-experimental groups ( each containing 20 teeth ) and each group was filled with their respective experimental material s. After longitudinal sectioning of root , SEM examination was done to determine the overall gap between retro grade material s and cavity walls in terms of length and width of the gap ( maximum ) at the interface . Descriptive statistical analysis was performed to calculate the means with corresponding st and ard errors , median and ranges along with an analysis of variance and Tukey 's test . Results : The least overall gap was observed in GMTA followed by PC and WMTA . While after statistically analyzing the various data obtained from different groups , there was no significant difference among these three groups in terms of marginal adaptation . Conclusion : GMTA showed the best overall adaptation to root dentinal wall compared to PC and WMTA . Being biocompatible and cheaper , the PC may be an alternative but not a substitute for MTA Objective : This study compared the marginal adaptation of mineral trioxide aggregate ( MTA ) and MTA-like material s as root-end fillings after incubation in phosphate buffer saline ( PBS ) , a synthetic tissue fluid , for either 1 week or 2 months . Material s and Methods : In this experimental study , seventy-two extracted human single-rooted teeth were prepared and obturated with gutta-percha and AH26 sealer . The apical 3 mm of the roots were resected . Root-end cavities were prepared with an ultrasonic retrotip . The specimens were r and omly divided into three groups ( n=24 ) and filled with either ProRoot MTA , OrthoMTA , or RetroMTA . Half of the specimens in each group were stored in PBS for 1 week the other half for 2 months . Epoxy resin replicas from the resected root-end surfaces and longitudinally sectioned roots were fabricated . The gaps at the material /dentin interface were measured using a scanning electron microscope ( SEM ) . Transversal , longitudinal , and overall gap sizes were measured . The data were analyzed using Kruskal-Wallis and Mann-Whitney tests . The significance level was set at p < 0.05 . Results : There were no significant differences between the marginal adaptation of ProRoot MTA , RetroMTA , and OrthoMTA in both transverse and longitudinal sections after incubation for either 1 week or 2 months ( p > 0.05 ) . In addition , the test groups were not significantly different regarding the overall mean gap values ( p > 0.05 ) . Conclusion : Under the conditions of this study , there was no difference between the marginal adaptation of ProRoot MTA , OrthoMTA , and RetroMTA as root-end filling material s after exposure to PBS for either 1 week or 2 months After 2 yrs ' follow-up , mineral trioxide aggregate ( MTA ) appeared suitable for this purpose A prospect i ve outcome study of  periradicular surgery  using microsurgical techniques and root-end filling with mineral trioxide aggregate ( MTA ) was performed . Nonhealing endodontically treated teeth ( n = 321 ) were included in the study . Surgery was completed under local anesthesia using a st and ardized clinical protocol . Patients were recalled periodically and examined for signs and symptoms of failure . Thirty-nine teeth were lost from recall . Of the 276 teeth examined , 163 showed complete healing radiographically with no other signs and symptoms ; 82 teeth had no symptoms but incomplete or uncertain healing , and 31 teeth showed nonhealing ( three had persistent pain despite evidence of complete radiologic healing and eight teeth did not heal for reasons unrelated to the surgical treatment ) . The overall success rate was 88.8 % , including all teeth with no clinical symptoms . In this study , the use of MTA as a root-end filling , following microsurgical techniques , showed a high success rate AIM To assess the success rate of the root-end filling material , Mineral Trioxide Aggregate ( MTA ) . METHODOLOGY Referred adult patients were recruited using strict entry criteria and r and omly allocated to receive MTA or IRM . A st and ardized surgical technique was employed : the root end was resected perpendicularly and a root-end cavity was prepared ultrasonically and filled . A radiograph taken immediately after surgery was compared with those taken at 12 and 24 months . Customised film holders and the paralleling technique were used ; radiographs were assessed by two trained observers using agreed criteria . The results from 122 patients ( 58 in IRM group , 64 in MTA group ) after 12 months and 108 patients ( 47 in IRM group , 61 in MTA group ) for the 24-month review period were analysed using the chi2 test . RESULTS The highest number of teeth with complete healing at both times was observed when MTA was used . When the numbers of teeth with complete and incomplete ( scar ) healing , and those with uncertain and unsatisfactory healing were combined , the success rate for MTA was higher ( 84 % after 12 months , 92 % after 24 months ) compared with IRM ( 76 % after 12 months , 87 % after 24 months ) . However , statistical analysis showed no significant difference in success between material s ( P > 0.05 ) at both 12 and 24 months . CONCLUSIONS In this study , the use of MTA as a root-end filling material result ed in a high success rate that was not significantly better than that obtained using IRM INTRODUCTION The aim of apical surgery is to hermetically seal the root canal system after root-end resection , thereby enabling periradicular healing . The objective of this nonr and omized prospect i ve clinical study was to report results of 2 different root-end preparation and filling methods , ie , mineral trioxide aggregate ( MTA ) and an adhesive resin composite ( Retroplast ) . METHODS The study included 353 consecutive cases with endodontic lesions limited to the periapical area . Root-end cavities were prepared with sonic microtips and filled with MTA ( n = 178 ) , or alternatively , a shallow concavity was prepared in the cut root face , with subsequent placement of an adhesive resin composite ( Retroplast ) ( n = 175 ) . Patients were recalled after 1 year . Cases were defined as healed when no clinical signs or symptoms were present and radiographs demonstrated complete or incomplete ( scar tissue ) healing of previous radiolucencies . RESULTS The overall rate of healed cases was 85.5 % . MTA-treated teeth demonstrated a significantly ( P = .003 ) higher rate of healed cases ( 91.3 % ) compared with Retroplast-treated teeth ( 79.5 % ) . Within the MTA group , 89.5%-100 % of cases were classified as healed , depending on the type of treated tooth . In contrast , more variable rates ranging from 66.7%-100 % were found in the Retroplast group . In particular , m and ibular premolars and molars demonstrated considerably lower rates of healed cases when treated with Retroplast . CONCLUSIONS MTA can be recommended for root-end filling in apical surgery , irrespective of the type of treated tooth . Retroplast should be used with caution for root-end sealing in apical surgery of m and ibular premolars and molars This in vitro study used rhodamine B fluorescent dye and a confocal microscope to evaluate the sealing ability of amalgam , super EBA , and a mineral trioxide aggregate when used as root end filling material s. Thirty single-canal teeth were cleaned , shaped , and obturated with gutta-percha and root canal sealer . After application of nail polish to the external surface , the apical 3 mm of each root was resected and 3-mm deep root end preparations were made . The roots were r and omly divided into three groups and the root end preparations filled with the experimental material s. All roots were then exposed to an aqueous solution of rhodamine B fluorescent dye for 24 h , longitudinally sectioned , and the extent of dye penetration measured using a confocal microscope . Statistical analysis showed that the mineral trioxide aggregate leaked significantly less than amalgam and super EBA UNLABELLED Carious pulp exposure in permanent molars of children is a common incident . Mineral trioxide aggregate is a new material that possesses numerous exciting possibilities for pulp therapy . AIM The purpose of this study was to evaluate the efficiency of MTA as a direct pulp capping agent in young permanent teeth . METHODS Thirty asymptomatic permanent molars with pulp exposures were treated by pulp capping using MTA . At each recall ( 6 12 , 18 and 24 months ) , the teeth were assessed clinical ly , through pulpal sensitivity tests , as well as radiographically to evaluate periapical healing . RESULTS None of the cases reported spontaneous pain at the six months follow up and the pulp showed signs of vitality and absence of periapical radiolucency . At 24 months , the clinical and radiographic success rate was 93 % with evidence of continued root growth . CONCLUSION Pulp capping with MTA is recommended for teeth with carious pulp exposures specially immature teeth with high potential for healing INTRODUCTION The purpose of the present study was to evaluate the clinical outcomes of endodontic microsurgery when super ethoxy-benzoic acid ( Super EBA ; Harry J. Bosworth , Skokie , IL ) and mineral trioxide aggregate ( MTA ) were used as root-end filling material s in a prospect i ve r and omized controlled study . METHODS Of the 388 teeth eligible for endodontic microsurgery , 128 teeth were excluded from the study , and 260 teeth were r and omly assigned to either the Super EBA group or the MTA group with equal numbers using the " minimization method . " Endodontic microsurgical procedures were performed according to the Yonsei protocol reported in a previous study and were carried out by a single operator . The patients were followed up at 3 , 6 , and 12 months . The primary outcome measure was the change in the apical bone density at 12 months , and the secondary outcome measures were the presence of clinical symptoms or abnormal findings at 12 months . RESULTS A total of 192 teeth were examined at the 12-month follow-up ; 102 teeth were in the Super EBA group , and 90 were in the MTA group . The overall success rate was 94.3 % , with a success rate of 95.6 % ( 86/90 teeth ) for MTA and 93.1 % ( 95/102 teeth ) for Super EBA . The statistical analysis of the success rate results did not show any significant difference between the groups ( P = .472 ) . CONCLUSIONS In this prospect i ve r and omized controlled study , there was no significant difference in the clinical outcomes of endodontic microsurgery when Super EBA and MTA were used as root-end filling material Introduction : This prospect i ve r and omized controlled study evaluated the clinical and radiographic outcome of endodontic microsurgery when using iRoot BP Plus Root Repair Material ( BP‐RRM ; Innovative BioCeramix Inc , Vancouver , BC , Canada ) or mineral trioxide aggregate ( MTA ) as the retro grade filling material and analyzed the relationship between some potential prognostic factors and the outcome of the surgery . Methods : By using strict inclusion and exclusion criteria , 240 teeth were successfully enrolled and r and omly and equally allocated to either the MTA or BP‐RRM treatment group . A st and ardized surgical procedure was performed by a single operator . The patients were followed up at 1 week , 3 months , 6 months , and 12 months ; follow‐up included clinical and radiographic examination . Clinical and radiographic evaluations acquired at the 12‐month follow‐up were taken as the primary outcome . For the identification of prognostic factors , the dichotomous outcome ( success vs failure ) was taken as the dependent variable . Results : A total of 158 teeth were analyzed at the 12‐month follow‐up , including 87 teeth in the MTA group and 71 teeth in the BP‐RRM group . The success rate in the MTA and BP‐RRM groups was 93.1 % ( 81/87 teeth ) and 94.4 % ( 67/71 teeth ) , respectively ( P > .05 ) . Three significant outcome predictors were identified : quality of root filling ( P < .05 ) , tooth type ( P < .05 ) , and size of the lesion ( P < .05 ) Conclusions : These results suggest that BP‐RRM is comparable with MTA in clinical outcome when used as root‐end filling material s in endodontic microsurgery AIM The aim of the present study was to clinical ly and radiographically evaluate Mineral Trioxide Aggregate ( MTA ) as an agent for pulpotomy in primary teeth and to compare it with that of Formocresol ( FC ) pulpotomy . METHOD Seventy first and second primary m and ibular molars of children were chosen on patients who required minimum two pulpotomies in either arch or same arch . After the st and ardized technique of Pulpotomy with MTA and Formocresol , all molars were treated with a thick mix of Zinc oxide Eugenol cement into the coronal pulp chamber followed by preformed stainless steel crown . The children were followed up for clinical and radio graphical examination after 6 , 12 and 24 month for Pain , Swelling , Sinus/fistula , Periapical changes , Furcation radiolucency and internal resorption . RESULTS MTA represents 97 % clinical success rate in comparison to Formocresol with 85 % success . Radiographically also MTA showed more promising results with 88.6 % success in comparison to Formocresol with 54.3 % . CONCLUSIONS Thus , MTA pulpotomy has emerged as an easier line of treatment to save the premature loss of primary teeth due to caries or trauma PURPOSE The purpose of this study was to compare mineral trioxide aggregate ( MTA ) with calcium hydroxide ( Ca(OH)2 ) clinical ly and radiographically as a pulpotomy agent in immature permanent teeth ( apexogenesis ) . METHODS Fifteen children , each with at least 2 immature permanent teeth requiring pulpotomy ( apexogenesis ) , were selected for this study . All selected teeth were evenly divided into 2 test groups . In group 1 , the conventional Ca(OH)2pulpotomy ( control ) was performed , whereas in group 2 , the MTA pulpotomy ( experimental ) was done . The children were recalled for clinical and radiographic evaluations after 3 , 6 , and 12 months . RESULTS The follow-up evaluations revealed failure due to pain and swelling detected at 6 and 12 months postoperative evaluations in only 2 teeth treated with Ca(OH)2 . The remaining 28 teeth appeared to be clinical ly and radiographically successful 12 months postoperatively . Calcific metamorphosis was a radiographic finding in 2 teeth treated with Ca(OH)2 and 4 teeth treated with MTA . CONCLUSIONS Mineral trioxide aggregate showed clinical and radiographic success as a pulpotomy agent in immature permanent teeth ( apexogenesis ) and seems to be a suitable alternative to calcium hydroxide AIM To compare the effectiveness of mineral trioxide aggregate ( MTA ) , calcium hydroxide ( CH ) and formocresol ( FC ) as pulp dressing agents in carious primary teeth . METHODOLOGY Forty-five primary m and ibular molars with dental caries in 23 children [ AUTHOR QUERY : How many children ? ] between 5 and 9 years old were treated by a conventional pulpotomy technique . The teeth were r and omly assigned to the experimental ( CH or MTA ) or control ( FC ) groups . After coronal pulp removal and haemostasis , remaining pulp tissue was covered with MTA paste or CH powder in the experimental groups . In the control group , diluted FC was placed with a cotton pellet over the pulp tissue for 5 min and removed ; the pulp tissue was then covered with zinc oxide-eugenol ( ZOE ) paste . All teeth were restored with reinforced ZOE base and resin modified glass-ionomer cement .  Clinical and radiographic successes and failures were recorded at 3 , 6 , 12 , 18 and 24 month follow-up . RESULTS Forty-three teeth were available for follow-up . In the FC and MTA groups , 100 % of the available teeth were clinical ly and radiographically successful at all follow-up appointments ; dentine bridge formation could be detected in 29 % of the teeth treated with MTA . In the CH group , 64 % of the teeth presented clinical and radiographic failures detected throughout the follow-up period , and internal resorption was a frequent radiographic finding . CONCLUSIONS Mineral trioxide aggregate was superior to CH and equally as effective as FC as a pulpotomy dressing in primary m and ibular molars . Internal resorption was the most common radiographic finding up to 24 month after pulpotomies performed with CH Objectives : The aim of this study was to evaluate marginal adaptation of mineral trioxide aggregate ( MTA ) , calcium enriched mixture ( CEM ) cement , Biodentine and BioAggregate in presence of normal saline and human blood . Material s and Methods : In this in-vitro experimental study , 80 extracted single-rooted human teeth were instrumented and filled with gutta-percha . After resecting the root-end , apical cavity preparation was done and the teeth were r and omly divided into 4 groups (N=20)(a total of 8 subgroups ) . Root-end filling material s were placed in 3 mm root-end cavities prepared ultrasonically . Half the specimens in each group were exposed to normal saline and the other half to fresh whole human blood . After 4 days , epoxy resin replicas of the apical portion of sample s were fabricated and scanning electron microscopy ( SEM ) analysis was performed to find gaps in the adaptation of the root-end filling material s at their interface with dentin . The Kruskal-Wallis and Mann-Whitney tests were used for statistical analysis of data with P<0.05 as the limit of significance . Results : There were no significant differences in marginal adaptation of the 8 tested groups ( P>0.05 ) . Conclusion : Based on the results , blood contamination does not affect the marginal adaptation of MTA , CEM cement , Biodentine or BioAggregate OBJECTIVE To compare the effects of mineral trioxide aggregate ( MTA ) and calcium hydroxide ( CH ) for pulpotomy in primary molars . METHODS A r and omised , bilateral self-controlled clinical trial was design ed to compare the clinical effect of MTA and CH in pulpotomies in primary molars in 4- to 9-year-old children . Children with two similar-sized cavities on bilateral primary molar counterparts requiring pulpotomies were included . The two contralateral molars in each patient were r and omly assigned to MTA or CH treatment . Clinical and radiographic examinations were performed to evaluate the treatment results at post-treatment recall . RESULTS Seventeen pairs of self-controlled contralateral teeth were available for follow-up evaluations . The success rate of MTA was 94.1 % ( 16/17 ) , while the success rate of CH was 64.7 % ( 11/17 ) . Internal root resorption was the most frequent reason for failure in the CH group . Crown discolouration was common in the MTA-treated group . CONCLUSION MTA was more successful than CH for pulpotomies in primary molar teeth , and may be a suitable replacement for CH in primary molar pulpotomies
On the basis of available evidence , MTA presented good marginal adaptation to dentine walls .
This systematic review analysed the literature comparing marginal adaptation of mineral trioxide aggregate ( MTA ) with other filling material s in root-end cavities .
