Comparison of CaOH with MTA for Direct Pulp Capping A comparative study on dental pulp response to calcium hydroxide, white and grey mineral trioxide aggregate as pulp capping agents Direct Pulp Capping with Calcium Hydroxide, Mineral Trioxide Aggregate, and Biodentine in Permanent Young Teeth with Caries: A Randomized Clinical Trial Clinical assessment of mineral trioxide aggregate (MTA) as direct pulp capping in young permanent teeth.
This practice -based , r and omized clinical trial evaluated and compared the success of direct pulp capping in permanent teeth with MTA ( mineral trioxide aggregate ) or CaOH ( calcium hydroxide ) .  Thirty-five practice s in Northwest PRECEDENT were r and omized to perform direct pulp caps with either CaOH ( 16 practice s ) or MTA ( 19 practice s ) . Three hundred seventy-six individuals received a direct pulp cap with CaOH ( n = 181 ) or MTA ( n = 195 ) . They were followed for up to 2 yrs at regular recall appointments , or as dictated by tooth symptoms . The primary outcomes were the need for extraction or root canal therapy . Teeth were also evaluated for pulp vitality , and radiographs were taken at the dentist ’s discretion . The probability of failure at 24 mos was 31.5 % for CaOH vs. 19.7 % for MTA ( permutation log-rank test , p = .046 ) . This large r and omized clinical trial provided confirmatory evidence for a superior performance with MTA as a direct pulp-capping agent as compared with CaOH when evaluated in a practice -based research network for up to 2 yrs ( Clinical Trials.gov NCT00812887 ) Context : Vital pulp therapy has been known as one of the treatment options to preserve pulp after being exposed by trauma or caries . Aim : To investigate human pulpal response to white and grey mineral trioxide aggregate ( WMTA , GMTA ) and Dycal ( MTA ) as pulp capping agents . Setting and Design : Human volunteers were participated in this r and omized clinical trial . Material s and Methods : This study was conducted on 90 intact first and second premolars of human maxillary and m and ibular teeth . The teeth were r and omly assigned into three groups of 30 each . Under local anesthesia , teeth were exposed and capped either with GMTA , WMTA , or Dycal . After 30 , 60 , and 90 days 10 teeth of each group were extracted and prepared for histologic observation . Statistical Analysis : Histopathologic data were analyzed by χ2 , Kruskal Wallis and Mann Whitney tests . Results : the calcified bridge in teeth that were capped with GMTA was significantly thicker than Dycal at 30 and 60 days ( P= 0.015 and P=0.002 , respectively ) ; whereas WMTA showed significantly thicker calcified bridge than Dycal at 90 days ( P=0.02 ) . In addition , GMTA specimens showed significantly less inflammation compared to Dycal sample s at 90 days interval ( P=0.019 ) . No significant difference was found between GMTA and WMTA in terms of calcified bridge thickness and pulp inflammatory response to the capping material s ( P>0.05 ) . Conclusions : Based on the result of this study , both types of MTA can be suggested as the material s of choice for direct pulp capping procedure instead of Dycal as hard setting calcium hydroxide cement Introduction Direct pulp capping treatment is intended to preserve pulp vitality , to avoid or retard root canal treatment , and , in cases with an open apex , to allow continued root development . Historically , calcium hydroxide ( CH ) was the gold st and ard material , but nowadays calcium silicate material s ( CSMs ) are displacing CH because of their high bioactivity , biocompatibility , sealing ability , and mechanical properties . However , more r and omized clinical trials are needed to confirm the appropriateness of CSMs as replacement material s for CH in direct pulp capping procedures . Methods A r and omized clinical trial was conducted that included 169 patients ( mean age , 11.3 years ) from the Maipo district ( Chile ) . The inclusion criterion was patients with 1 carious permanent tooth with pulpal exposure , a c and i date for a direct pulp capping procedure . The patients were r and omly allocated to one of the experimental groups ( CH , Biodentine , or mineral trioxide aggregate [ MTA ] ) . Clinical follow‐up examinations were performed at 1 week , 3 months , 6 months , and 1 year . The Fisher exact test was performed . Results At the follow‐up examination at 1 week , the patients showed 100 % clinical success . At 3 months , there was 1 failure in the CH group . At 6 months , there were 4 new failures ( 1 in the CH group and 3 in the MTA group ) . At 1 year , there was another failure in the CH group . There were no statistically significant differences among the experimental groups . Conclusions CSMs appear to be suitable material s to replace CH . Although no significant differences were found among the material s studied , Biodentine and MTA offered some advantages over CH . HighlightsThis trial compared the efficacy of calcium hydroxide , MTA , and Biodentine as pulp capping material s in young permanent molars . MTA and Biodentine are suitable material s to replace calcium hydroxide in pulp capping procedures .Pulp capping in carious teeth is a successful treatment when done under good clinical protocol 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
In conclusion , MTA has a higher clinical success rate for direct pulp capping comparing to calcium hydroxide , and might be a suitable replacement for calcium hydroxide
Direct pulp capping is one of the most common dental practice s in endodontic therapy .
This systematic review and meta- analysis aim to determine whether the effect of mineral trioxide aggregate ( MTA ) and calcium hydroxide for direct pulp capping is different , as measured by the clinical and radiographic analysis .
