Abstract
OBJECTIVE The aim of this study was to analyze the internal morphology of deciduous molars through the use of computed microtomography in a sample from Rio de Janeiro. MATERIAL AND METHODS Thirty maxillary and 30 mandibular deciduous molars (n = 60), divided in first and second primary molars, were scanned by computed microtomography. The teeth were evaluated for root number, root canals, Vertucci classification, root curvature, presence of lateral canals, furcation dentin thickness, structure model index (SMI), volume, and canal surface area. RESULTS The results showed 100% of maxillary molars had three roots and Vertucci type I canal was more prevalent in this group. In the mandibular ones, type IV was more frequent in the mesial root and class I in the distal root and the cavo-interradicular canal occurred in 2 specimens. Dentin thickness in the furcation region measured 1.53 and 1.59 mm in the maxillary and mandibular, respectively. Volume and area parameters varied according to the evaluated canals and SMI demonstrated that all canals had a cylindrical shape. CONCLUSION More detailed information about the internal anatomy of the primary molars has been described, which may help strategies in the preparation of these root canals.

CHILDREN (BASEL, SWITZERLAND) 2024; 11:574. [PMID: 38790569 PMCID: PMC11119415 DOI: 10.3390/children11050574] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/05/2024] [Revised: 04/30/2024] [Accepted: 05/08/2024] [Indexed: 05/26/2024]
Abstract
AIM This systematic review and meta-analysis aimed to evaluate the success rates of pulpotomy treatment for irreversible pulpitis in primary teeth. METHODS This study was registered and conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols. Relevant studies published between January 1980 and April 2023 were identified across eight online databases and two paediatric dentistry textbooks. Study selection, data extraction, and quality assessment were conducted by multiple investigators independently. Data analysis involved single-arm and two-arm meta-analyses, leave-one-out sensitivity analysis, meta-regression, and assessment of publication bias. The risks of bias were evaluated using the Cochrane Collaboration's assessment tools. The levels of evidence were determined using the Oxford Centre for Evidence-Based Medicine (OCEBM) tool. RESULTS Five primary studies were included. The weighted mean overall success rates at 6-month and 12-month follow-ups were 97.2% and 94.4%, respectively. Two-arm meta-analysis revealed no significant difference (p > 0.05) between the use of mineral trioxide aggregate (MTA) and non-MTA bioceramic-based materials as pulpotomy medicaments. The sample size of each study did not affect the degree of data heterogeneity. Egger's test revealed no significant publication bias. CONCLUSIONS Pulpotomy may be regarded as an alternative modality for treating primary teeth with irreversible pulpitis. Nevertheless, future well-designed trials and extended follow-up periods are warranted.

Abstract
OBJECTIVES This study evaluated the antimicrobial activity, clinical and radiographic outcome of pulpectomy in primary teeth using either 1% sodium hypochlorite (NaOCl) or 2% chlorhexidine (CHX) as irrigants. MATERIALS AND METHODS A randomized double-blind controlled clinical study in which primary teeth were allocated to 1% NaOCl (n = 20) and 2% CHX (n = 20) groups. Microbiological collections were performed before and after irrigation for agar culture and real-time polymerase chain reaction (qPCR). Clinical and radiographic success was assessed at different times. Data were submitted to descriptive analysis, chi-square, Mann-Whitney, and Wilcoxon tests (p < .05). RESULTS For 1% NaOCl, the following clinical and radiographic success rates were observed: 7 days (93%/80%); 30 days, 3 and 6 months (100%). For 2% CHX: 7 days (73%/53%); 30 days (93%); 3 months (100%/93%); 6 months (100%) (p > .05). One percent NaOCl and 2% CHX effectively reduced total microorganisms (p < .05) but not mutans streptococci (p > .05). In qPCR analysis, the solutions promoted a reduction of total bacteria and Streptococcus mutans, and no difference was observed between times and groups (p > .05). CONCLUSIONS One percent NaOCl and 2% CHX were effective for clinical and radiographic success and antimicrobial activity in primary teeth submitted to pulpectomy. CLINICAL RELEVANCE Studying the antimicrobial activity and clinical and radiographic outcomes of pulpectomy in primary teeth using NaOCl and CHX as irrigants is clinically relevant because it provides information for optimizing treatment protocols and improving the quality of care for pediatric patients. It contributes to evidence-based practice and can potentially lead to better outcomes, reduced complications, and enhanced patient experiences.

Abstract
Background Preservation of necrotic primary teeth is important. Pulpectomy is the gold standard treatment in this situation. Reinfection is the main cause of failure in pulpectomy. The application of regenerative endodontic therapy in mature teeth has the rationale of restoring dental-pulp-like tissue and preventing reinfection. Aims and objectives The current study was designed to clinically and radiographically assess regenerative endodontics therapy in necrotic primary molars in comparison to zinc oxide eugenol (ZOE) pulpectomy. Materials and methods A double-blinded randomized controlled trial with three parallel arms and a 1:1:1 allocation ratio was conducted. A total of 54 necrotic primary molars in 39 healthy children aged 4-7 years old were randomly allocated as follows group I-control group, in which ZOE pulpectomy was performed. Group II and III-experimental groups, in which regenerative endodontic therapy (RET) was performed. Modified triple antibiotic paste (mTAP) and Metapex™ were used as intracanal medicaments in groups II and III, respectively. Clinical and radiographic assessments were recorded at baseline, 6 and 12 months. Chi-squared and Fisher's exact tests were used to compare the qualitative data, while Friedman's test was used to study the changes by time within each group. Results Nonstatistically significant differences were reported between the three groups at the 6 and 12 months follow-ups regarding the clinical or radiographic assessment (p-value = 0.327 and effect size = 0.22), (p-value = 0.055 and effect size = 0.118), respectively. Conclusion Regenerative endodontic therapy (RET) yielded comparable results to pulpectomy. However, the use of 5 mg/mL mTAP in RET represented the highest level of clinical as well as radiographic insignificant failure. Clinical significance Regenerative endodontic therapy (RET) provides an acceptable biological alternative to pulpectomy.

Survival Analysis and Risk Factors of Pulpectomy among Children with Severe Early Childhood Caries Treated under General Anesthesia: A Retrospective Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:1191. [PMID: 36673947 PMCID: PMC9859510 DOI: 10.3390/ijerph20021191] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/28/2022] [Revised: 01/08/2023] [Accepted: 01/09/2023] [Indexed: 06/17/2023]
Abstract
OBJECTIVES This study aims to retrospectively evaluate the survival rate of pulpectomy performed under dental general anesthesia (DGA) through long-term follow-up and to explore the risk factors associated with treatment failure. METHODS The medical records of the children who were diagnosed with S-ECC and received pulpectomy treatment under general anesthesia (GA) from 1 August 2014 to 1 December 2019, in the Stomatological Hospital of Xi'an Jiaotong University, were collected. Two dentistry postgraduates extracted the necessary information and filled in a predesigned excel form. Survival analysis was performed using the Kaplan-Meier method. The shared frailty model was used to explore possible factors affecting the success rate of pulpectomy in primary teeth. RESULTS A total of 381 children (mean age 3.49 ± 0.90) with S-ECC and 1220 teeth were included in the study, including 590 primary anterior teeth and 630 primary molars. The overall 35-month survival rate was 38.5%, which was 52.9% for anterior teeth and 31.1% for molars. The overall median survival time was 31 months, in which anterior teeth were 35 months and molars were 26 months. The older the children were, the greater the risk of treatment failure (HR 1.56, 95% CI 1.09, 2.24). The risk of pulpectomy failure of primary molars was 1.9 times that of primary anterior teeth (95% CI 1.36, 2.65) and the teeth with abnormal radiological findings before treatment was 1.41 times higher than that of teeth without imaging abnormalities (95% CI 1.74, 3.36). CONCLUSION The survival rate of primary tooth pulpectomy is acceptable but decreased gradually with time. The failure rate of pulpectomy in primary molars is higher than that of primary anterior teeth. When the primary caries has extended to the pulp and resulted in a nonvital lesion, pulpectomy could be an option for maximum retention of the primary tooth.

Abstract
This systematic review aims to analyse the available evidence concerning the use of citric acid (CA) in endodontics treatment and to assess its results in terms of different considerations: effect on smear layer removal, influence on sealer bond strength, activation effect by means of sonic or ultrasonic devices, effects on dentine surface, antibacterial activity, and effectiveness boost for regenerative procedures, releasing growth factors from dentin. To evaluate the results of CA as a final irrigant and compare them to other chelating agents. This review followed the PRISMA checklist. An electronic search was conducted in MEDLINE (OVID), Scopus (Elsevier) and the Web of Science (Thomson Reuters) databases. Risk of bias of included studies was evaluated using the modified CONSORT checklist and the PRIRATE checklist 2020 guidelines. 39 studies fulfilled the eligibility criteria to be included in this review: 27 in vitro studies using extracted human teeth, 10 in vitro studies using human dentin disks, and 2 RCT. Citric acid has proven to be effective in smear layer removal, showing better results in coronal and middle root thirds, improving its effect when combined with manual dynamic activation. There is no agreement regarding citric acid effect on sealer adhesion and adaptation to root canal walls due to heterogeneity within studies. Citric acid irrigation can decrease dentine microhardness and cause decalcification and erosion, especially when used before NaOCl. Citric acid has proven to be beneficial in regenerative endodontic procedures due to higher TGF-β1 release.Trial registration: Prospero database CRD42021267055.

Abstract
BACKGROUND To retrospectively investigate the success rate of primary-molar pulpectomy performed under general anaesthesia and the potential risk factors that affect the 24-month success rate. METHODS The case data and two-year follow-up records of children (aged 3-6 years) who received pulpectomy in primary molars performed under general anaesthesia were reviewed and assessed. Potential risk factors included age, gender, decayed-missing-filled teeth, endodontic diagnosis, tooth location, and postobturation sealing of the pulp chamber floor with MTA. With a two-year follow-up period, the outcomes of all the primary molars were classified into success and failure. Survival analysis was used to assess the outcomes. The Kaplan-Meier method was used to analyse the success rate. Univariate and multivariate Cox proportional hazards regression models were used to evaluate the potential risk factors associated with the overall survival of primary molars. RESULTS A total of 410 teeth from 163 children (88 boys and 75 girls) were included in this study. The overall two-year success rate was 66.1% for all primary molars. The mean overall survival time for this study was 22.1 (95% CI, 21.73‒22.48) months. Multivariate Cox regression analysis demonstrated that endodontic diagnosis (irreversible pulpitis or periapical periodontitis), tooth location (maxillary or mandibular primary molar), and postobturation sealing of the pulp chamber floor (MTA or no-MTA) were significant risk factors for overall survival in this study (P < .05). The differences in success rates were not statistically significant in terms of age, gender, and decayed-missing-filled teeth (P > .05). CONCLUSIONS When compared to teeth diagnosed with irreversible pulpitis, those with periapical periodontitis failed more frequently. Postobturation sealing of the pulp chamber floor with MTA improved the success rate of pulpectomy in primary molars, especially when the inflammation did not spread to the periradicular area.

Abstract
OBJECTIVES Preserving the primary teeth is important, as they play an important role in the integrity of the dental arch, the development of the craniofacial complex, speech, and chewing. This study aimed to evaluate the effectiveness of both Mineral Trioxide Aggregate (MTA) and Bioceramic putty in primary molar pulpotomy with symptoms of irreversible pulpitis. MATERIALS AND METHODS In this study, 40 s primary mandibular molars in 40 healthy children aged 6-8 years were examined and classified into 2 groups according to the material: group A, with 20 primary molars capped by MTA, and group B, with 20 teeth capped by Bioceramic putty. Clinical and radiographic evaluation of the treatment results was carried out after 1 week, 3 months, 6 months, 9 months, and 1 year. RESULTS Clinical and radiological success rates in the MTA group reached 95%, where a case of failure was observed after a year of follow-up. In the Bioceramic group, the success rate reached 100% after a year of follow-up, without any statistically significant differences between groups (p = .311). CONCLUSIONS Pulpotomy using biocompatibility materials (MTA-Bioceramic) in primary molars with symptoms of irreversible pulpitis is considered effective due to the better advantages of the use of Bioceramic over MTA. This clinical trial was approved by Australian New Zealand Clinical Trials (12621001631897).

Are electronic apex locators accurate in determining working length in primary teeth pulpectomies? A systematic review and meta-analysis of clinical studies. Int Endod J 2022; 55:989-1009. [PMID: 35808837 DOI: 10.1111/iej.13798] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2022] [Revised: 07/03/2022] [Accepted: 07/04/2022] [Indexed: 11/26/2022]
Abstract
BACKGROUND The lack of a well-defined apical constriction in primary teeth raises concerns regarding the accuracy of electronic apex locators (EALs) for measuring working length. OBJECTIVES To evaluate the accuracy of EALs in determining working length in primary teeth pulpectomies. METHODS Two reviewers searched ten databases up to September 2021. Clinical studies evaluating the accuracy of the electronic measurement of working length in primary teeth pulpectomies were included. Studies without a comparison group, with samples smaller than ten root canals, and that did not use a multiple frequency EAL were excluded. A meta-analysis was conducted to assess the paired differences in mean lengths between measurements obtained by electronic and comparative methods. In addition, a meta-analysis of proportion was applied according to the level of difference between the measures. The risk of bias and applicability of the studies were assessed using the QUADAS-2 tool. The certainty of evidence was assessed with the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach. RESULTS Twenty-nine studies were included in the qualitative analysis and twenty-three in the quantitative analysis. The methods of comparison for the electronic measurement were the radiographic method, radiovisiographic, scanning electron microscopy, and direct visualization. The meta-analysis showed that the electronic measurement tends to be shorter than radiographic measurement, while the other methods showed no difference. The proportion analysis showed a higher pooled proportion of difference values between electronic and comparative measurements within -0.5 to +0.5 mm (69.31%). The certainty of the evidence suggested very low confidence in estimating the outcome. DISCUSSION The results of this review denote a good performance of the EALs in determining working length in primary teeth pulpectomies. However, these results are based on clinical studies with low methodological quality and high heterogeneity, which require careful interpretation for clinical practice. CONCLUSIONS Although the results suggest acceptable accuracy of EALs in determining working length in primary teeth pulpectomies, the low quality of the included studies and the very low certainty of the evidence require clinicians to interpret these results with caution. More robust evidence is required to support that these devices are accurate for primary teeth.

Abstract
Efficient working length determination is essential for a successful endodontic treatment. The purpose of the present study was to evaluate whether the method for determining the working length of root canals (radiographic or electronic) influences the obturation level of primary molars. Thus, a controlled, triple-blind, randomized clinical trial was conducted. Sixty-four children aged 6 to 9 years with an indication for primary molar pulpectomy were included. Participants were divided into two groups according to the method used to determine the working length of the root canals: (G1) radiographic and (G2) using an electronic apex locator. The study had 3 operators: #1 performed the clinical procedures, except the electronic measurement; #2 performed radiographic measurement and final evaluation of obturation level; and #3 performed eligibility criteria and electronic measurement. Adequacy of obturation level was evaluated based on the final conventional radiography and it was recorded as acceptable or unacceptable (short or overfilled). Data were analyzed with repeated measures logistic regression. There was no difference between the obturation level of primary molars measured by radiographic and electronic methods (p > 0.05). The other investigated variables (age, tooth type, dental arch position, last instrumentation file, and canal location) also did not influence the obturation level (p > 0.05). In conclusion, both measurement methods resulted in similar adequacy of obturation level in primary molars after pulpectomy.

Radiographic and antimicrobial evaluation of enterococcus Faecalis and Actinomyces Israelii micro-organisms after photodynamic therapy (aPDT). Photodiagnosis Photodyn Ther 2021; 35:102433.

Abstract
This study evaluated the action of Antimicrobial Photodynamic Therapy (aPDT) on Enterococcus faecalis and Actinomyces israelii. Samples were taken from the root canal system, at different stages of treatment and bacteria were identified through qPCR. Fifty teeth (incisors, canines, and premolars) with pulp necrosis and periapical lesion diagnosis were randomly selected and divided into 2 groups: Group 1 (G1) - Endodontic Therapy with Mechanical Chemical Preparation (MPQ) and intracanal medication; Group 2 (G2) - Endodontic therapy with MPQ, intracanal medication, and 2 applications of aPDT. APDT was performed with application of 0.005% methylene blue, wavelength of 660 nm, and 90 seconds. Follow-up was performed with an initial x-ray and an x-ray 60 days after the end of treatment. The radiographs were scored evaluated by two examiners to classify periapical repair: total repair, partial repair, doubtful repair, or no repair. Enterococcus faecalis was found more frequently in G1 than G2. Actinomyces israelii was found equally in G1 and G2. Evaluation of the two bacteria between collections 1, 2 and 3, showed that there was no difference, both in G1 and in G2. There was association between the variables group and repair classification in radiographs evaluation. APDT did not promote better results in endodontic treatment, being similar to conventional treatment. However, this study pointed out that molecular methods may not be efficient in detecting bacteria after treatment, and colony-forming units may complement, being an effective quantifying method. Therefore, new studies must be carried out to show the possible effectiveness of aPDT.

Apical debris extrusion during instrumentation of oval root canals in primary teeth using manual versus motorized files: an ex vivo study. Sci Rep 2021; 11:3859. [PMID: 33594151 PMCID: PMC7887259 DOI: 10.1038/s41598-021-83522-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2020] [Accepted: 02/04/2021] [Indexed: 11/30/2022] Open
Abstract
This study aimed to assess the apical extrusion of debris during instrumentation of primary canines using three endodontic file types. Forty-five extracted primary canines were randomly assigned to three instrumentation groups (n = 15): Hand K-files; and the motorized Kedo-S files and XP-endo Shaper files. The apically extruded debris produced during the procedure was collected and dried in pre-weighed Eppendorf tubes, and the mass of debris was calculated. The time required for the endodontic procedure was also recorded. Analysis of variance (ANOVA) and Tukey’s post hoc test were used with a significance level set at 5%. XP-endo Shaper and Kedo-S files extruded significantly less debris compared with hand K-files with means of 0.84 ± 0.31 and 1.20 ± 0.67 mg respectively, compared to 2.13 ± 0.31 mg (p < 0.0001). No significant difference was found between the two motorized files. Less time was required to complete the procedure with the XP-endo Shaper compared to the hand K-files (p < 0.0001) and Kedo-S files (p < 0.0001). Within the limitations of the present study, it may be concluded that motorized files extruded less debris and required less instrumentation time compared to traditional K-files, which could benefit paediatric patients with root canal treatment needs.

Abstract
BACKGROUND Endodontic treatment of primary teeth can be time-consuming. AIM To compare hand and rotary files regarding the time for root canal chemical-mechanical preparation, child's behavior, apical limit of the obturation, and post-operative pain. DESIGN This secondary data from a randomized clinical trial with two parallel arms evaluated endodontic instrumentation in 88 children aged 4-9 years. Stratified and block randomization was performed into two groups: K-file hand and ProDesign Logic rotary files. The evaluated outcomes were the chemical-mechanical preparation time, child's behavior using the Frankl scale, apical limit of the obturation, and post-operative pain using the Faces Pain Scale-Revised. One operator and all outcome appraisers were blinded to the chemical-mechanical technique. Multiple linear regression, chi-square, and Fisher's exact test were performed. RESULTS The mean time for chemical-mechanical preparation using hand files was 24.5 (SD 4.0) minutes, and using rotary files, it was 17.0 (SD 2.5) minutes (P < .001). No difference was found between the instrumentation methods in the child's behavior, apical limit of the obturation, or post-operative pain. CONCLUSIONS The ProDesign Logic file reduced the average procedure time but presented no difference in the other variables studied when compared to the K-file.

Abstract
Background. This study was conducted to investigate root canal overfilling with different material placement techniques in primary teeth. Methods. A systematic search was undertaken by searching PubMed/MEDLINE and Scopus for English language peer-reviewed articles published until February 2018 that reported primary tooth pulpectomy overfilling. Two reviewers independently screened and identified studies in terms of the selection criteria and independently collected the data using a specially designed data extraction form. The overfilling rate was the primary summary measure. The weighted pooled overfilling rates were estimated by random-effects meta-analysis. Results. Twenty clinical and four in vitro studies met the eligibility criteria. In the clinical studies, the pooled overfilling rate for zinc oxide-eugenol (ZOE) was 23.3% with a lentulo spiral mounted on a handpiece, 22.7% with a hand-held lentulo spiral, and 17% with a plugger. The pooled overfilling rate for calcium hydroxide-based materials was 16.7% with a lentulo spiral mounted on a handpiece, 14.7% with a hand-held lentulo spiral, 19.6% with a syringe, and 25.7% with a plugger. In the in vitro studies, neither individual overfilling rates nor two-by-two comparisons were subjected to meta-analysis because of an inadequate number of studies. Conclusion. The lowest overfilling rate in the clinical studies was related to plugger and handheld lentulo spiral techniques for ZOE and calcium hydroxide-based materials, respectively.

Abstract
Evaluate the cytocompatibility of Calen®/ZO, Calcicur®, Vitapex®, Endoflas®, and zinc oxide/eugenol-based (ZOE) root canal pastes (RCP) to human primary osteoblasts (HPO) through a simplified model for primary teeth. The model employed pipette tips filled with 0.037 g of paste, exposed to 185 µL of culture medium for 24 h (n = 6). Release of components was analysed by Proton Nuclear Magnetic Resonance Spectroscopy (1H-NMR). HPO were exposed to conditioned media for 24 h. Cell viability was assessed by cell density and metabolic activity, and release of interleukin 6 (IL-6), vascular endothelial growth factor (VEGF) and fibroblast growth factor (bFGF) by immunological assay. Physicochemical properties and antimicrobial efficacy were also evaluated. 1H-NMR spectra analysis showed similarity between ZOE, Endoflas®, Calcicur®, and Vitapex® compared to Calen®/ZO and positive control, which showed distinct released components. Calen®/ZO and Calcicur® exhibited high alkaline pH in all periods and showed similar solubility. Calen®/ZO, ZOE, and Vitapex® showed similar flow rate. Calen®/ZO, Calcicur®, and Vitapex® did not exhibit antimicrobial efficacy. Calen®/ZO presented cytotoxicity (p < 0.05). Pastes did not increase IL-6 release compared to control. Apart from Vitapex®, all pastes significantly induced VEGF/bFGF release. Interactive effects among released products may affect biological response to filling pastes. Calcicur®, ZOE, Endoflas® and Calen®/ZO presented good to moderate cytocompatibility, with low impact on pro-inflammatory cytokine release and induction of growth factors of interest to tissue repair. This simplified model, specific for the evaluation of the cytocompatibility of RCPs on primary teeth, suggests how these pastes might contribute to bone repair in clinical situations of apical periodontitis in children.

Abstract
OBJECTIVE To assess whether lesion sterilization and tissue repair (LSTR) technique resulted in similar clinical and radiographic success outcomes as compared with pulpectomy in primary teeth. MATERIALS AND METHODS Randomized clinical trials comparing LSTR with pulpectomy by means of clinical and radiographic parameters were included. Risk of bias was assessed using Cochrane methodology and the certainty of evidence was determined by GRADE. RESULTS Six articles were included. Conventional pulpectomy was favored with respect to radiographic success frequency in the systematic review. Four studies were included in meta-analyses. Based on the clinical results at 6 months (RR = 0.99, 95% CI, 0.94-1.04, p = 0.67; I2 = 0%), 12 months (RR = 0.97, 95% CI, 0.90-1.04, p = 0.34; I2 = 0%), and 18 months (RR = 0.89, 95% CI, 0.77-1.04, p = 0.14; I2 = 0%) and radiographic findings at 6 months (RR = 0.91, 95% CI, 0.78-1.06, p = 0.23; I2 = 9%), 12 months (RR = 0.87, 95% CI, 0.65-1.18, p = 0.38; I2 = 64%), and 18 months (RR = 0.84, 95% CI, 0.69-1.02, p = 0.08; I2 = 0%), there was no difference observed regarding success between the two treatments. The quality of evidence ranged from moderate to very low. CONCLUSIONS No difference between the LSTR and pulpectomy approaches could be confirmed by meta-analyses. The quality of evidence according to the GRADE scheme ranged from moderate to very low. CLINICAL RELEVANCE The present meta-analyses could not demonstrate the superiority of one treatment over the other.

Abstract
BACKGROUND Working length is an important step in primary teeth pulpectomy. AIM To evaluate whether there is a significant difference in the accuracy of electronic apex locators compared to the conventional radiography in working length measurements. DESIGN Sixty-four children (192 canals) between 5 and 9 years of age with indication for pulpectomy of a primary molar were included after eligibility criteria. A radiographic measurement was obtained from pre-operative radiography from the cusp tip to the apex or resorption of the root. The electronic measurement was obtained from a complete measurement of the canal with an electronic device up to the apex. Data were analysed with Bland-Altman plots and Wilcoxon test. Statistical significance was set at P ≤ .05. RESULTS Statistically, there is not any significant difference between radiographic and electronic measurements for the palatal canal or distal canal, as well as mesiobuccal canals (P > .05). Statistically, there, however, is a significant difference between the measurements for the distobuccal canal and mesiolingual canal measurements (P < .05). High internal consistency for both radiographic and electronic methods was achieved (α ≅ 1). CONCLUSIONS Electronic and radiographic methods are similar in determining the length measurement of the root canals in primary teeth pulpectomies, except in distobuccal or mesiolingual canals.

Abstract
The aim of this study was to examine the smear layer removal capacity of various etidronate treatments. Seventy-eight roots were instrumented up to apical size X4 and randomly divided into five treatment groups and a positive control group (n = 13). Groups were as follows: irrigation with 5 ml of sterile saline (control) for 3 min, 5 ml of 17% ethylenediaminetetraacetic acid (EDTA) for 3 min, 5 ml of 9% A1-hydroxyethylidene-1,1-bisphosphonate (HEBP) for 3 min, 5 ml of 18% HEBP for 3 min, irrigation with 5 ml of 1% sodium hypochlorite (NaOCl) + 9% HEBP for 3 min, and 5 ml of 2% NaOCl + 18% HEBP for 3 min. The roots were examined using a scanning electron microscope. The smear layer scores in the 2% NaOCl + 18% HEBP group were lower than those in the other treatment groups and the control group (p < .05). There were no significant differences among the treatment groups in the smear layer scores of the coronal and middle thirds. However, the smear layer scores in the 2% NaOCl + 18% HEBP treatment group were lower those in the 9% HEBP and 18% HEBP treatment groups in the apical third (p < .05). In the clinical setting, the recommended concentration of HEBP is 18%, and it should be used with an oxidizing agent to ensure optimum smear layer removal.

Abstract
This study indented to assess the clinical and radiographic assessment of Allium sativum extract as an intracanal irrigant for pulpectomy of primary molars. Ninety children with 110 teeth submitted were categorized into two groups. Clinical and radiographic success rates were checked at 3, 6, and 12 months. Qui-square test at a level of significance was ˂0.05. There was no statistically significant difference (p ˂ .05) between the two groups that has not been detected clinically or radiographically. Clinical and radiographic success rates of garlic extract at 3 months were (80% and 72.7%), which declined at 6 and 12 months to be 76.4% 6 and 74.5% respectively. For NaOCl group, clinical and radiographic success rates were 87.3% and 85.5% at 3 months, 87.3% and 87.3% at 6 months and 89.1% and 87.3% at 12 months. A. sativum extract can be used efficiently as an irrigant for pulpectomy of primary molar root canals.

Abstract
OBJECTIVE The purpose of this study was to compare the efficacy of different irrigation protocols on smear layer removal in root canals of primary teeth by scanning electron microscopy (SEM). MATERIAL AND METHODS The study was conducted with 40 extracted maxillary primary incisor teeth divided into four groups (n = 10) as 1% sodium hypochlorite (NaOCl), 10% ethylenediaminetetraacetic acid (EDTA)+1% NaOCl, 6% citric acid (CA)+1% NaOCl, and 0.9% physiological saline (PS). After the irrigation procedures, root canal walls were examined by SEM and the efficacies of irrigation solutions in smear layer removal were scored and compared. Data were analyzed using Kruskal-Wallis, Friedman and Siegel Castellan tests. RESULTS The smear layer removal was found to be statistically more effective in groups of 10% EDTA + 1% NaOCl and 6% CA + 1% NaOCl when compared with the other groups (p < .05). Smear removal efficacy was statistically significantly higher in coronal and medium thirds when compared with the apical regions in the experimental groups. CONCLUSIONS It was concluded that 10% EDTA + 1% NaOCl and 6% CA + 1% NaOCl could be alternative irrigation protocols regarding smear layer removal. However, due to the absence of erosive dentinal changes, it might be suggested that using 6% CA + 1% NaOCl can be recommended compared to 10% EDTA + 1% NaOCl in primary root canals.

Abstract
This study evaluated clinical and radiographic twelve-month outcomes of root canal treatments (CT) with smear layer removal, performed in primary teeth, using two different root canal filling materials. Pulpectomy was performed on 27 primary teeth with necrosis or irreversible pulpitis, caused by dental caries or trauma, in 23 children (2-7 years old). A single trained operator performed the CT in a single visit in cases without periapical or interradicular radiolucency (PIR) or in multiple visits in cases with PIR. Participants were selected based on specific inclusion and exclusion criteria, and randomly allocated into two groups: Group 1 (G1) - iodoform paste (iodoform + camphorated parachlorophenol + ointment comprising prednisolone acetate 5.0 mg and rifamycin 1.5 mg); Group 2 (G2) - Calen®/ZO paste. Treated teeth were restored with composite resin immediately after the root canal filling. The outcomes were evaluated clinically and radiographically according to specific criteria. Two blinded and standardized evaluators assessed the radiographic outcomes. We used descriptive analyses due to the small sample size. CTs were performed due to caries lesions in 70.4% of the cases and due to trauma in 29.6%. Only one tooth of G1 was unsuccessful; hence, pulpectomy performance in both groups was not influenced by the filling material, nor by any other analyzed variable. The level of the root canal filling was better in the Calen®/ZO group. The clinical and radiographic twelve-month outcomes indicated successful treatment, independently of the root filling material used.

Abstract
PURPOSE The purpose of this study was to compare the antimicrobial efficacy of the EndoVac system and conventional needle irrigation to eliminate E faecalis in primary molar root canals. STUDY DESIGN 60 extracted human primary second molar roots were instrumented up to an apical size .04/35 and randomly divided into two groups; Group 1: conventional needle (n=30) and Group 2: EndoVac (n=30), and four subgroups (two experimental subgroups; (a) 2.5% sodium hypochlorite (NaOCl) + ethylenediaminetetraacetic acid (EDTA) (n=20), (b) ozonated water (OW) + EDTA (n=20), and control groups (c) 5.25% NaOCl (n=10) and (d) saline (n=10). All roots were sterilized and then inoculated with E.faecalis. Before and after final irrigation procedures, root canals were sampled and the grown colony forming units (CFUs) were counted. Data were analyzed by Kruskall-Wallis and Mann-Whitney U tests using a 0.05 significance level. RESULTS The EndoVac reduced more bacteria than the conventional needle did but it was not statistically significant (p>0.05). NaOCl alone or followed by EDTA totally eliminated bacteria. OW + EDTA showed higher reduction of bacteria but could not totally eliminate bacterias. CONCLUSIONS In the context of bacterial elimination, the EndoVac was not significantly better than the conventional needle. Although, there were fewer CFU/mg when using EndoVac, there was not any statistically significant superiority to conventional needle irrigation. An OW+EDTA regimen showed antibacterial effect in the primary molar root canals but it was significantly less effective than NaOCl+EDTA.

Abstract
OBJECTIVE This study investigated the presence of Enterococcus faecalis in primary teeth with primary root canal infections and related to the possible failure of pulpectomy outcome after 36 months. MATERIAL AND METHODS Root canal samples were obtained from 25 out of 244 patients using the sterile paper cone method. The identification of E. faecalis was done with culture and molecular tests using species-specific 16S rRNA gene-based polymerase chain reaction (PCR). After 36 months, the pulpectomy outcome was evaluated. RESULTS Enterococcus faecalis was found in five (20%) samples, and dental caries were the cause of primary infection in all of them. Pulpectomy outcome was evaluated only in teeth that completed the entire clinical protocol and were followed up to 36 months (n = 8). From these, 75% (n = 6) were successful and 25% (n = 2) failed. E. faecalis was present in 50% of both successful and failed cases. CONCLUSIONS Enterococcus faecalis was not related to the failure of endodontic treatment of primary teeth.

Abstract
Abstract Although endodontic treatment is widely recommended for compromised dental pulp, there is no information regarding the factors associated with failures in primary teeth. The aim of this study was to evaluate the survival and factors associated with failure of pulpectomies performed in primary teeth by dental students. The sample comprised patients treated at a University Dental Service and required endodontic treatment in primary teeth. The study investigated treatment-related variables and patient factors potentially associated with treatment failure. Pulpectomy survival was analyzed by Kaplan-Meier estimator followed by log-rank test (p<0.05). The analysis included 81 pulpectomies performed in 62 children (5.6±1.5 years). The survival reached 62.9% up to 12 months follow-up. Most failures occurred in the first 3 months (p<0.001). Teeth with carious lesions at the start of treatment presented more failures than those with restorations or history of trauma (p=0.002). The survival of endodontically treated teeth restored with composite was higher than the ones filled with GIC (p=0.006). Pulpectomy performed in two or more sessions resulted in more failures (p=0.028). Patients presenting gingivitis had more failures in the endodontic treatment (p=0.022). The failures of root canal treatment in primary teeth were more prone to occur in a short time and when the treatment was performed in teeth presenting carious lesions. The use of composite instead of GIC increased the survival of pulpectomies. Repeated sessions for endodontic treatment and lack of oral hygiene habits had a negative effect on the results.

Abstract
Objectives: To evaluate the outcome of vital pulp
therapy in primary teeth with irreversible pulpitis by using calcium-enriched
mixture (CEM) cement according to clinical and radiographic assessment. Participants and Methods: Fifty primary molar teeth with irreversible pulpitis in 50 children aged 6-8 years underwent pulpotomy using CEM cement as the dressing material. Following pulpotomy, pain intensity was
evaluated by use of a visual analog scale at 1 and 7 days from the treatment and
in clinical appointments at 3, 6 and 12 months after baseline. Radiographic
evaluation was performed at 6 and 12 months. Data were analyzed using the
McNemar test. Results: A total of 42 children (mean age 7.26 ± 0.82 year) completed the study. After one day treatment 56 % of children
reported complete relief of pain and after 7 days 62% reported the same.
However, two children complained of increased pain 1 day after treatment. None of
the children reported pain in the subsequent appointments. One child complained
of tenderness in percussion after 6 months. Pulp canal obliteration was the most
common change in the radiographic assessment. There was no significant
difference between clinical (92.8%) and radiographic (90.4%) success (p=0.990). Conclusion: Pulpotomy using CEM cement could present a
successful treatment in primary molar teeth with irreversible pulpitis.

Abstract
AIM To evaluate the efficacy of ethanolic extract of Salvadora persica (S. persica) and BioPure MTAD (a mixture of a tetracycline isomer, an acid, and a detergent) in removing the intracanal smear layer of primary teeth. MATERIALS AND METHODS The root canal of 40 extracted human primary anterior teeth were cleaned, shaped and grouped into experimental (n = 30) and control (n = 10). The root canals of the positive (n = 5) and the negative control (n = 5) were irrigated for 3 minutes with 5 ml of 17% ethylenediaminetetraacetic acid (EDTA) or saline respectively. The canals in the experimental groups were irrigated for 3 minutes with 5 ml of 1 mg/ml ethanolic extract of S. persica (n = 15) or BioPure MTAD (n = 15) and then flushed with 2 ml of saline. The presence or absence of smear layer at the coronal and middle portion of each canal were examined under a scanning electron microscope (SEM). RESULTS A significant difference (p = 0.004) in smear layer removal between S. persica and MTAD at the middle third of the canal was observed. MTAD solution was as effective as 17% EDTA in removing the smear layer. CONCLUSION MTAD was significantly more effective in smear layer removal than S. persica solution at the middle third of the canal wall. CLINICAL SIGNIFICANCE Both tested irrigant solutions have the ability to remove the intracanal smear from primary root dentin following cleaning and shaping of the root canal and could be an alternative to EDTA.

Abstract
OBJECTIVES The effects of different EndoActivator® (EA) sonic activation protocols on root canal debridement efficacy were examined. METHODS Root canals in 48 single-rooted teeth were instrumented, irrigated initially with NaOCl and divided into 6 groups (N=8) based on the application time of QMix (antimicrobial calcium-chelating irrigant), and the time and sequence of EA irrigant activation - Positive Control: 90s QMix; Negative Control: 90s saline; Group 1A: 15s QMix+15s QMix with EA-activation; Group 1B: 30s QMix+30s of QMix with EA-activation; Group 2A: 15s QMix with EA-activation+15s QMix; Group 2B: 30s QMix with EA-activation+30s QMix. Split roots were examined with scanning electron microscopy for assignment of smear and debris scores in locations along the coronal, middle and apical thirds of the canals. The overall cleanliness of pooled canal locations in the Positive Control and the 4 experimental groups were compared with chi-square tests. RESULTS Significant differences were detected among the 5 groups (P<0.001). Post hoc pairwise comparisons indicated that the overall canal cleanliness was in the order (from best to worst): 1B=2B>2A>1A>Positive Control. Completely clean canals could not be achieved due to the absence of continuous irrigant flow for EA to clear intraradicular debris. CONCLUSIONS Irrespective of the sonic activation sequence, irrigant activation for 30s during a 60-s period of QMix application appears to maximise the smear layer and debris removal potential of the EndoActivator® system. CLINICAL SIGNIFICANCE Sonic activation of root canal irrigants produces cleaner root canals and reduces the time required for final delivery of a canal wall smear later-removing irrigant when compared to the use of needle irrigation alone.
