    Input: Pulpotomies were performed on 83 primary molars in 62 patients .  Ferric sulfate or formocresol was placed on the pulpal stumps , and teeth were followed for 3- , 6- , and 12-month periods . After the one-year follow-up , 28 of 29 teeth treated with ferric sulfate ( FS group ) were considered successful and 21 of 27 teeth treated with formocresol ( FC group ) were judged to be successful . The FS group demonstrated greater combined clinical and radiographic success than the FC group at the one-year recall ( P < 0.05 ) . Although the results of this study are promising , further study with longer observation periods is warranted before this technique can be recommended PURPOSE The purpose of this study was to compare long-term outcomes of ferric sulfate pulpotomy ( FS ) and primary tooth root canal therapy ( RCT ) in vital pulps of deciduous molars exposed to caries lesions . METHODS A total of 291 molars were treated in 130 children . One hundred and eighty-two molars received FS  and 109 received RCT by r and om selection . RESULTS At 3-year re- assessment , 29 molars ( 15 FS , 14 RCT ) were available for clinical and radiographic examination . Two independent pediatric dentists evaluated periapical radiographs of the treated molars . Molars were classified 1 of 4 outcomes : ( 1 ) N = normal treated molar ; ( 2 ) H = nonpathologic radiographic change present ; ( 3 ) P(o ) = pathologic change present , follow-up in 6 months ; ( 4 ) P(x ) = pathologic change present extract immediately . Survival analysis was applied . A good level of agreement between raters was found for molars with outcome P(x ) ( K = 0.79 ) . No difference in radiographic outcomes was demonstrated 3 years after treatment ( chi2 = 1.4 ) . Survival analysis demonstrated a 3-year survival probability of 0.62 for FS-treated molars and 0.92 for RCT molars . Survival of RCT molars was significantly greater than for FS molars ( Wilcoxon : P = .01 ; log-rank : P = .02 ) . CONCLUSIONS RCT -treated molars demonstrated significantly greater survival than FS-treated molars 3 years after treatment PURPOSE The objective of this outcome study was to compare ferric sulfate pulpotomy ( FS ) and primary tooth root canal therapy ( RCT ) on cariously exposed vital pulps of primary molars . METHODS A total of 291 molars were treated in 130 children--182 molars received FS and 109 received RCT by r and om selection . RESULTS At 2-year re assessment , 116 molars ( 73 FS , 43 RCT ) were available for clinical and radiographic examination . There was no clinical evidence of pathosis in 96 % of FS and 98 % of RCT molars . Two independent pediatric dentists evaluated periapical radiographs of the treated molars . Molars were classified into 1 of 4 outcomes : ( 1 ) N -- normal treated molar , ( 2 ) H -- nonpathologic radiographic change present , ( 3 ) P(O)--pathologic change present , follow-up in 6 months , and ( 4 ) P(X)--pathologic change present , extract immediately . Survival analysis was applied . A good level of agreement between raters was found for molars with outcome P(X ) ( kappa=0.745 ) . Intrarater reliability was good for molars with outcome P(X ) ( kappa=0.710 ) . Significantly greater numbers of FS than RCT molars were rated P(X ) at the 2-year recall ( chi2=5.8 ; P=.02 ) . No significant difference in survival between the 2 types of vital pulp treatments was detected in log rank tests ( P=.22 ) . CONCLUSIONS Outcomes for FS were poorer than RCT outcomes at 2 years ; however , at 2 years , the survival rates were not statistically different OBJECTIVES Although previous studies have examined the electrosurgical pulpotomy technique for primary teeth , no well-controlled , clinical human trials have been published . The purpose of this study was to prospect ively compare electrosurgical pulpotomies vs. formocresol pulpotomies in human vital primary molar teeth . DESIGN Fifty children were r and omly divided into two groups , 25 receiving an electrosurgical pulpotomy and 25 receiving a formocresol pulpotomy . RESULTS After at least 5 months postoperative observation time , the clinical and radiographic success rates for the electrosurgical groups were 96 and 84 % , respectively ; and for the formocresol group , 100 and 92 % , respectively . CONCLUSION There were no statistically significant differences between the success rates for the two groups at the P < 0.05 level as tested by Fisher 's exact test . This study failed to demonstrate a difference in the success rate between the electrosurgical and formocresol pulpotomy techniques PURPOSE To evaluate the clinical and radiographic success of zinc oxide-eugenol ( ZOE ) , Calcicur , Sealapex and Vitapex in primary molar pulpectomies . METHODS 80 primary molars , showing signs of pulpal and /or periapical involvement , with no abnormal mobility , were selected from 76 children aged between 4 - 9 years-old , free from systemic disease . Radiographic evaluation was done to exclude teeth showing internal or pathological external root resorption and /or inadequate bone support . The selected teeth ( 20 in each group ) were r and omly treated with ZOE , Sealapex , Calcicur and Vitapex . The procedure involved primarily a one-visit pulpectomy . The teeth were evaluated clinical ly and radiographically every 2 months for a period of 18 months . RESULTS In the ZOE group , all pulpectomies were successful . In the Sealapex group , two pulpectomies and in the Calcicur group , four pulpectomies showed complete resorption of the material in the root canal . Although re-treatment was performed , those teeth had to be removed due to pathological root resorption . In the Vitapex group , although six pulpectomies showed resorption of the filling material within the canals , this had no effect on the clinical and radiographical success of the treatment Seventy primary molar teeth , carious exposed , symptom free , without any sign of root resorption in children aged from 3 to 6 years ( main age 4.3 yr ) were treated with conventional pulpotomy procedures . Ferric sulfate 15.5 % solution ( applied for 15 second for 35 teeth ) and formocresol solution ( five minute procedure of Buckley 's formula for next 35 teeth ) have been used as pulpotomy agents . In both groups , pulp stumps were covered with zinc-oxide eugenol paste . Permanent restorations were stainless steel crowns . Clinical check up was every three-months and radiographic follow-up time was six and twenty months after treatment . Our results within this period revealed 100 % clinical success rate in both groups . Radiographic success rate was in both groups 97.2 % , while in 2.8 % cases has shown internal root resorption . On the basis of these results , we can recommend ferric sulfate as a pulpotomy agent in primary teeth in substitution for formocresol at the moment 
    Output:
    
Primary outcomes were extraction s following pulp treatment and long term effects .
REVIEW ER 'S CONCLUSIONS Based on the available RCTs , there is no reliable evidence supporting the superiority of one type of treatment for pulpally involved primary molars .
