OBJECTIVES The aims of this study were to evaluate iodoform base material s for root canal treatment of necrotic primary teeth , and to compare them with traditionally used zinc oxide and eugenol ( ZOE ) . SAMPLE AND METHODS Zinc oxide and eugenol and Vitapex ( a premixed calcium hydroxide and iodoform paste ) were compared for root canal treatment in 52 necrotic primary teeth in two groups of children with a mean age of 5 years and 8.4 months . All the patients were followed-up clinical ly and radiographically 3 months and 10 - 16 months postoperatively . RESULTS The overall success rates of Vitapex and ZOE were 100 % and 78.5 % , respectively . Using Fisher 's Exact Test , the difference was statistically significant ( P < 0.05 ) . CONCLUSION Both ZOE and Vitapex gave encouraging results .  Vitapex , however , can be used more safely whenever there is a doubt about the patient 's return for follow-up AIM To compare and evaluate the volumetric analysis of pre- and post-root canal instrumentation in primary teeth using h and and rotary files and also to analyse the volume of root canal filling . MATERIAL S AND METHODS A total of 20 primary teeth were divided into two groups r and omly and subjected to spiral computed tomography ( SCT ) analysis before and after instrumentation . For manual technique ( Group 1 ) , teeth were prepared using K files and rotary ( Group 2 ) preparation was performed with Mtwo files .  Volumetric enlargement was calculated using Osirix software . Root canals were then filled with rotary lentulospiral using zinc oxide-eugenol cement ( ZOE ) . The filled volume in each canal was measured using SCT and the percentage of obturated volume was calculated . The data were statistically analysed using paired t-tests . RESULTS There was a statistically significant difference in the volume of root canal enlarged in both the groups . Rotary files showed significant increase in the volume compared to K files . Mtwo instrumented root canals showed good obturated volume compared to manual technique , although voids were common in both the groups . CONCLUSION Rotary root canal instrumentation may be indicated for utilization in primary teeth , for enhancing root canal preparation and good quality of root canal filling 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 Calcium hydroxide , a material widely used for the treatment of permanent teeth has not been used frequently for pulpectomy in primary teeth . A comparative evaluation of calcium hydroxide and zinc oxide eugenol used as  root canal filling material s in primary molars is presented Microleakage is related to recurrent decay , inflammation of vital pulps , and reinfection of previously treated root canals . The purpose of this investigation was to compare the abilities of new adhesive cements and conventional nonadhesive controls to prevent microleakage under stainless steel crowns on primary anterior teeth . St and ardized preparations were made , and stainless steel crowns were adapted . Specimens were assigned r and omly to cement groups : zinc phosphate ( ZP ) , polycarboxylate ( PC ) , glass-ionomer ( GI ) , resin-modified glass-ionomer ( RMGI ) , RMGI with a dentin bonding agent ( RMGI + DBA ) , adhesive composite resin ( ACR ) and zinc oxide eugenol ( ZOE ) .  Specimens were stored in water , aged artificially , stained , embedded , and sectioned , and the microleakage was measured . Group means and st and ard errors were calculated . ANOVA discerned differences among groups ( P < 0.0001 ) , and Turkey 's multiple comparisons testing ( P < 0.05 ) ranked the groups from least to most microleakage as follows : [ RMGI + DBA , RMGI , ACR , GI ] , [ ZP ] , and [ PC , ZOE ] . The adhesive cements significantly reduced microleakage Background : Fiber reinforced composite ( FRC ) posts are cemented with resin cements . It is reported that using resin cements in canals sealed with eugenol-containing sealers reduces the post retention . However , there is controversy on the subject . Aims : The aim was to investigate the influence of eugenol-containing sealers and the amount of dentin removal from root canal with different post diameters on retention of FRC posts . Setting s and Design : It was an in vitro study Material s and Methods : The roots of sixty teeth were cut with 14 mm distance from the apex and were instrumented to the working-length of 13 mm . The teeth were r and omly distributed into 2 groups ( n = 30 ) . Following storage in normal saline for 7 days , the sample s in both the groups were further divided into 3 subgroups ( n = 10 ) . Canals in the experimental subgroups ( I , II , III ) were obturated by gutta-percha and eugenol-containing sealer ; and in the control subgroups ( IV , V , VI ) without any sealer . After storage in normal saline for 7 days , the post space was prepared by # 3 , # 2 , and # 1 drills of DT Light-Post system . Post was cemented with Panavia-F2.0 resin-cement . A composite core was built for each sample . All sample s were thermo cycled for 1000 cycles . The sample s were tested for post retention with a mechanical testing machine . Statistical Analysis : Data were analyzed by two-way ANOVA and Tukey-HSD test . Results : There was not a significant difference in retention between FRC posts # 1 and # 2 ( P > 0.05 ) . Post # 3 was more retentive than posts # 1 and # 2 ( P < 0.05 ) . ZOE sealer significantly reduced the retention of posts ( P = 0.024 ) , however , increasing post-space diameter significantly increased post retention in canals coated with ZOE sealer ( P = 0.002 ) . Conclusions : Eugenol-containing sealer reduced the retention of FRC posts cemented with resin cement . Removing more dentin from root-canals treated with eugenol-containing sealer for placing larger diameter posts caused an increase in post retention Objectives The objective of this study was to evaluate the bond strength of three root-end filling material s ( MTAA – MTA Angelus , MTAS – experimental MTA Sealer , and ZOE- zinc oxide and eugenol cement )  in retro grade preparations performed with different ultrasonic tips ( CVD , Trinity , and Satelec ) . Material s and method Ninety 2-mm root sections from single-rooted human teeth were used . The retro grade cavities were prepared by using the ultrasonic tips , coupled to a device for position st and ardization . The specimens were r and omly divided into nine groups : CVD MTAA ; CVD MTAS ; CVD ZOE ; Trinity MTAA ; Trinity MTAS ; Trinity ZOE ; Satelec MTAA ; Satelec MTAS ; Satelec ZOE . Each resin disc/dentin/root-end filling material was placed in the machine to perform the push-out test . The specimens were examined in a stereomicroscope to evaluate the type of failure . Data were su bmi tted to statistical analysis using ANOVA and Tukey tests ( α = 0.05 ) . Results The highest bond strength was observed for the CVD tip irrespective of the material used ( P < 0.05 ) . There was no significant difference for the Trinity TU-18 diamond and S12 Satelec tips ( P > 0.05 ) . MTAA and MTAS showed highest bond strength . The most common type of failure was adhesion between the filling material and dentin wall , except for ZOE , where mixed failure was predominant . Conclusions The CVD tip favored higher bond strength of the root-end filling material s. MTA Angelus and experimental MTAS presented bond strength to dentin prepared with ultrasonic tips . Clinical relevance Root-end preparation with the CVD tip positively influences the bond strength of root-end filling material s. MTA Angelus and experimental MTAS present bond strength to be used as root-end filling material
There seems to be no convincing evidence to support the superiority of any material over ZOE , and both ZOE and IP + Ca appear to be suitable as root canal fillings for deciduous teeth
The aim of this systematic review was to determine whether there is a root canal filling for deciduous teeth equally or more effective than zinc oxide-eugenol cement ( ZOE ) .
