RESUMO
BACKGROUND: Traditionally, pediatric endodontics lacked access to the full potential of rotary instruments. These instruments, designed for the permanent root canal system, often presented limitations when used in primary teeth. To address this, exclusive pediatric rotary files with regular improvements have been introduced, featuring superior cutting efficiency with a focus on precise alignment. This design offers the advantage of reduced risk of ledges, perforations, instrument separation, and canal transportation. This study aimed to compare and evaluate the effectiveness of Pro AF Baby Gold and Kedo-S rotary files in preparing primary tooth root canals during pulpectomy procedures through a meta-analysis. METHODOLOGY: The review was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines. The review searched electronic databases from 2000 to February 2024 for studies evaluating the efficacy of Pro AF Baby Gold and Kedo-S files in terms of canal instrumentation, transportation, and centering ratio. The Cochrane risk of bias (ROB)-2 tool assessed quality, with analyses conducted using RevMan software version 5.3. The standardized mean difference (SMD) served as the summary with a random effects model (P < 0.05). RESULTS: Out of the five studies identified through the eligibility criteria, three were deemed suitable for a meta-analysis, while all five were included in a qualitative synthesis. The quality assessment revealed a presence of moderate-to-low ROB. The pooled analysis using SMD did not show any statistically significant differences between the files, except for the centering ratio in the mesiobuccal canal, where the Kedo-S file performed slightly better. In addition, the absence of any significant asymmetry in the funnel plot suggests that there is likely no publication bias present in the data. CONCLUSION: Pro AF Baby Gold files can be used as an alternative adjunct in pediatric endodontics to Kedo-S files and manual files.Prospero Registration: CRD42023469406.

BACKGROUND: Pharmacological methods, specifically sedatives, have gained popularity in managing the behavior of children during dental appointments. AIM: The aim of this study was to compare 1 m/kg intranasal dexmedetomidine, 0.3 mg/kg intranasal midazolam, and nitrous oxide in evaluating the level of sedation, behavior of the child, onset of sedation, physiologic signs, and adverse effects. MATERIALS AND METHODS: In this cross-over trial, 15 children aged 6-8 years were randomized to receive intranasal atomized dexmedetomidine, intranasal atomized midazolam, and inhalation nitrous oxide at three separate visits. After administering the sedative agent, a single pulpectomy was performed during each appointment, and the outcomes were recorded. The washout period between each visit was 1 week. RESULTS: All three sedative agents were equally effective in controlling overall behavior. Dexmedetomidine showed lower sedation level scores (agitated; score 9) than the other groups. There was a statistically significant difference in the onset of sedation, with dexmedetomidine having the longest onset of 36.2 ± 9.47 min. Coughing and sneezing were predominantly observed after administration of intranasal midazolam. Oxygen saturation levels were statistically lower in the intranasal midazolam group during local anesthesia administration and post-treatment. CONCLUSION: 0.3 mg/kg intranasal midazolam is as effective as nitrous oxide sedation for controlling behavior and providing adequate sedation in pediatric dental patients. However, 1 m/kg dexmedetomidine did not provide the same level of sedation and had a significantly longer onset. 0.3 mg/kg intranasal midazolam is an effective alternative to nitrous oxide sedation in anxious children.

AIM: To compare preparation times using manual, rotary, and reciprocating files during pulpectomy treatment of primary molars. SETTINGS AND DESIGN: This study was an in vitro, randomised, cross-sectional study. METHODS: The study was performed on 60 extracted human primary mandibular second molars. Only mesiobuccal canals were prepared using one of three preparation techniques; each preparation technique group comprised 20 canals. Canal preparations were performed by a single, skilled operator using stainless-steel (ss) K-files (ISO size 20-35), a ProTaper Gold SX file, and a WaveOne Gold Medium file following glide path preparation. Preparation times were recorded in second (s) with a digital stopwatch. STATISTICAL ANALYSIS: Preparation times were compared using analysis of variance and the Kruskal-Wallis analysis of variance, where appropriate. The level of significance was set at P ≤ 0.05. RESULTS: The mean preparation time using the ss K-files was significantly longer (186.4 s) than when using the ProTaper Gold SX (29.6 s) or WaveOne Gold Medium files (30.5 s) (P < 0.001). Similar preparation times were recorded when using the ProTaper Gold SX and WaveOne Gold Medium files (P = 0.939). CONCLUSION: Preparation times with the ProTaper Gold SX and WaveOne Gold Medium files were significantly faster than when using the ss K-files to prepare primary tooth root canals for pulpectomy. Similar preparation times were noted when using the rotary and reciprocation instrumentation groups (P > 0.05).

STUDY DESIGN: A randomised parallel controlled clinical trial was conducted between 2013 and 2015 at the University of Sao Paulo, Brazil, to assess the impact of pulpectomy or extraction on the oral health-related quality of life (OHRQoL) of children with pulp necrosis in primary molars. STUDY SELECTION: Children between the ages of 3 and 5 who were in good health but had extensive caries in at least one primary molar with signs of pulpal necrosis (also as seen radiographically, caries reaching the pulp with no signs of internal or external resorption) were considered for inclusion. Additionally, teeth with sufficient structure for rubber dam placement were also included. Children with any systemic, neurological, or other conditions that negatively impacted their growth were excluded. CLINICAL PROCEDURES AND SUCCESS CRITERIA: After computer-generated randomisation, 100 children were assigned randomly into two groups: 50 in the pulpectomy group and 50 in the dental extraction group. A paediatric dentist performed all procedures under local anaesthesia without sedation or general anaesthesia, and a rubber dam was used for pulpectomy with composite restoration in a single session. The OHRQoL scores were evaluated at baseline, 4, 8, and 12 months using the Brazilian version of the Early Childhood Oral Health Impact Scale (B-ECOHIS) via face-to-face interviews with parents conducted by a researcher trained in a single-blinded fashion. Additionally, the child's self-reported dental anxiety was measured using the Facial Image Scale (FIS), and dental pain was assessed using the Wong-Baker Faces Pain Scale (WBFPS) immediately after the treatment as secondary outcomes. RESULTS: The mean difference (SD) in the total B-ECOHIS score between baseline and after 12 months was 12.66 (6.79) for the pulpectomy group and 10.94 (9.28) for the extraction group, with effect sizes of 3.2 (95% CI: 2.42-4.20) and 1.4 (95% CI: 0.84-2.11), respectively. While both treatments significantly improved the children's OHRQoL after 12 months, the pulpectomy group showed greater long-term improvement compared to the extraction group, with mean differences (SD) of 4.86 (6.13) and effect sizes of 0.8 (0.46-1.13; p < 0.001). Moreover, children in the extraction group showed higher levels of anxiety compared with those in the pulpectomy group at 12-month follow-up (OR = 2.52; 95% CI = 1.30-4.89), and they reported 93% more odds of 'dental pain with high level' immediately after treatment than those in the pulpectomy group (OR = 1.93; 95% CI = 0.83-4.49). CONCLUSION: Children treated with pulpectomy in their necrotic primary molars were found to have better OHRQoL than those who had their primary molars extracted.

BACKGROUND: Pulpectomy continues to be the standard treatment recommendation for management of vital primary molars diagnosed with symptomatic irreversible pulpitis. The recent decade has seen a paradigm shift in the treatment concepts of how vital mature permanent molars diagnosed with irreversible pulpitis can be more conservatively managed using vital pulp therapy techniques like pulpotomy. However, despite emerging evidence indicating similarities between primary and permanent tooth pulp response to dental caries, there is limited research on whether pulpotomy can be similarly used as a definitive treatment modality for vital primary teeth with irreversible pulpitis. This randomised controlled trial (RCT) aims to compare the treatment effectiveness of pulpotomy versus pulpectomy in management of vital primary molars diagnosed with symptomatic irreversible pulpitis over a two-year period. METHODS/DESIGN: This clinical study is a parallel, two-armed, open label, non-inferiority RCT with a 1:1 allocation ratio between the experimental intervention arm (pulpotomy) and the active comparator arm (pulpectomy). Healthy cooperative children, between 4-9 years of age, who have painful primary molars with clinical symptoms typical of irreversible pulpitis will be recruited after obtaining informed consent from their parents/legal guardians. 50 vital primary molars clinically diagnosed with symptomatic irreversible pulpitis will be randomly distributed between the two treatment arms. The primary outcomes that will be assessed are clinical and radiographic success after six-months, one-year and two-years of the trial interventions. The influence of baseline pre-operative variables (age; gender; tooth type; site of caries; pre-operative furcal radiolucency; pre-operative pain intensity) and intra-operative factors (time taken to achieve haemostasis) on treatment outcomes will also be assessed. The secondary outcome evaluated will be the immediate (24 h and 7 d) post-operative pain relief afforded by the two treatment interventions. DISCUSSION: This trial seeks to provide evidence on whether pulpotomy treatment can be no worse than the standard pulpectomy treatment for the management of symptomatic irreversible pulpitis in vital primary molars. TRIAL REGISTRATION: ClinicalTrials.gov (NCT06183203). Registered on 30 January 2024.

BACKGROUND: Endodontic therapy in pediatric dentistry is a challenging procedure, especially for special needs, uncooperative, and very young patients. A new conservative approach which is the non-instrumental endodontic treatment (NIET) has been developed to simplify the management of primary teeth requiring pulpectomy. This review aimed to compare the efficiency of NIET and conventional endodontic treatment in primary teeth. METHODS: Electronic databases including MEDLINE (via PubMed), Cochrane Library (CENTRAL), and Scopus without restrictions on publication year or publication language were searched. Only randomized clinical trials reporting clinical and radiographical outcomes of NIET and conventional pulpectomy on primary teeth were considered eligible. Two reviewers extracted the data according to the PRISMA statement and assessed the bias risk using the revised Cochrane risk-of-bias tool and a meta-analysis was performed. RESULTS: From 3322 screened articles, seven articles meeting the inclusion criteria were included. The selected studies included 283 primary molars, of 213 children aged between 3 and 9 years, treated by NIET and conventional pulpectomy, and had follow-up periods ranging from 1 month to tooth exfoliation. Two studies reported good success rates for both the NIET technique and endodontic therapy with no statistically significant difference while three studies showed radiographical significant differences with a low success rate for the NIET technique. Only one study reported better outcomes in the pulpectomy group with statistically significant differences. The quantitative grouping of the included studies showed no significant differences between NIET and conventional endodontic therapy regarding clinical and radiographical success (p value > 0.05). CONCLUSION: No difference between the NIET technique and the conventional endodontic therapy in primary molars requiring pulpectomy could be confirmed. Results of the present review need to be interpreted with caution since the quality of evidence according to the GRADE was considered as moderate to very low. Therefore, additional clinical trials on the NIET technique are recommended.

A natural irrigation solution with a broad spectrum of antimicrobial coverage, triphala was selected for the pulpectomy procedure. Because of its natural ingredients, it is well-known for promoting tissue healing. It also supposedly has certain additional qualities as compared to usual irrigation solutions that are made chemically. Although 2.5% NaOCl is thought to be perfect since it meets most of the requirements for an irrigation solution but it cannot be optimized for pulpectomy procedure. Primary teeth that were recommended for pulpectomy underwent this randomized controlled experiment. Two groups of eighty-four primary teeth were randomly assigned to receive irrigations: triphala in Group A; 2.5% Sodium hypochlorite in Group B. Sample were taken from infected primary root canals. A sterile test tube with bhi broth as the transport media was used to collect pre- and post-irrigation samples using sterile absorbent paper tips. On agar media, microorganisms were cultivated and their mean colony count was assessed. Following the procedure, the patient's follow-up visits at one, two and three months were used to evaluate the clinical result. The post-microbial colony count was dramatically reduced (p<0.001) by both irrigation treatments. Triphala in Group A is demonstrating desirable efficacy. Clinical success was found satisfactory in both the groups studied (p<0.001). But statistically significant difference was not found (p=0.175). Considering undesirable properties of sodium hypochlorite triphala can be a better alternative as a root canal irrigants in pulpectomy of primary teeth.

PURPOSE: The objective of this multicentre randomised controlled trial was to compare the clinical/radiographic outcomes of cervical pulpotomy using calcium-enriched mixture cement (PCEM) and pulpectomy using Metapex (PM) in primary molars with irreversible pulpitis (IP). METHODS: A total of 134 primary molars from 94 children were randomly assigned to two intervention groups: the PCEM group (n = 74) and the PM group (n = 60). Baseline characteristics including age/gender/molar type/tooth type/jaw were recorded. The primary outcome measures were clinical/radiographic success rates assessed at the first and second follow-up appointments. Secondary outcomes included reasons for clinical/radiographic failures. Multiple logistic regression analysis was performed to determine the impact of various factors on the success rates. RESULTS: The mean age of the participants in both groups was similar (PCEM group: 5.4 years, PM group: 5.5 years). Gender distribution, molar type, tooth type, jaw, and number of practitioners were comparable between the groups. The clinical success rate at the first follow-up was 98.6% in the PCEM group and 96.4% in the PM group. At the second follow-up, the clinical success rate was 97.1% in the PCEM group and 91.1% in the PM group. The radiographic success rates at the first and second follow-up were 98.6% and 96.4% in the PCEM group and 96.4% and 91.1% in the PM group, respectively. Multiple logistic regression analysis did not reveal any significant association between the success rates and age/gender/molar type/jaw, or treatment groups (P > 0.05). CONCLUSION: In primary molars with IP, both simple/conservative cervical pulpotomy using calcium-enriched mixture cement and pulpectomy using Metapex demonstrated high clinical/radiographic success rates. No significant differences were observed between the two treatment modalities. These findings suggest that both techniques can be considered effective treatment options for managing primary molars with IP.

PURPOSE: Pulpectomy can be used for the management of deep dentinal carious lesions in primary teeth which can be restored. Mechanical preparation of root canals can be performed using hand or NiTi rotary files. However, this may cause dentinal stress and consequently dentinal microcracks. Hence, the aim was comparative evaluation of hand and rotary file systems on dentinal microcrack formation during pulpectomy procedure in primary teeth. METHODS: 60 extracted primary molar teeth were selected comprising of 80 root canals. Simple random sampling was used to divide root canals into four groups (n = 20): Group A-Hedstrom file, Group B-Pro AF Baby Gold rotary, Group C-ProTaper Next rotary, and Group D-unprepared group. Assessment was conducted on presence or absence of microcracks using Chi square test (p < 0.05). RESULTS: The total number of microcracks in Group A: one (5%), Group B: four (20%), Group C: nine (45%) and Group D: zero (0%) which was statistically significant (p = 0.002). At cervical third, the number of microcracks seen with Group A: one (5%), Group B: zero (0%), Group C: five (25%) and Group D: zero (0%) (p = 0.005). At the middle third, the number of microcracks seen in Group A: zero (0%), Group B: four (20%), Group C: four (20%) and Group D: zero (0%) (p = 0.029). CONCLUSION: The study concluded that dentinal microcracks are formed with both hand and rotary file systems in primary teeth. ProTaper Next showed significantly higher number of microcracks, followed by ProAF Baby Gold and H files.

BACKGROUND: Pulpotomy as a minimally invasive pulp therapy technique is the treatment of choice for carious pulp exposures, however many pediatric dentists perform pulpectomies in vital primary incisors. The aim of this split mouth randomized controlled study was to compare formocresol pulpotomy and zinc-oxide and eugenol pulpectomy in the treatment of vital pulp exposure in primary incisors. METHODS: Contralateral pairs of incisors were randomly assigned to receive pulpotomy or pulpectomy in children aging from 18 to 66 months old and were followed up for 12 months. RESULTS: 39 pairs of incisors were included. Clinical and radiographical success rates showed no statistical significant difference (p = 1, p = 0.8 respectively). Relative risk measures for clinical success rates (RR = 1.03, 95%CI 0.87 to 1.23) and for radiographic success rates (RR = 1.03, 95%CI 0.83 to 1.29) with CIs including number one showing no difference between the two groups. The Survival rate using Kaplan-Meier survival analysis score showed 82% for pulpotomy and 74% for pulpectomy at 12 months (P = 0.2). CONCLUSIONS: Both pulpotomy and pulpectomy techniques can be used successfully in the treatment of carious vital pulp exposure in primary incisors. TRIAL REGISTRATION: The trial was retrospectively registered in Clinicaltrials .gov with this identifier NCT05589025 on 21/10/2022.

AIM: The aim of this randomized clinical trial was to compare the impact of two management options for primary molars with pulp necrosis (pulpectomy or extraction) on children's oral health-related quality of life (OHRQoL). DESIGN: A total of 100 children aged 3-5 years with at least one necrotic primary molar were selected and randomized into the study groups. The Brazilian version of early childhood oral health impact scale (B-ECOHIS) was completed by the parent proxy reports at baseline and after 4, 8 and 12 months. Differences between the trial groups were assessed through bootstrap linear regression for B-ECOHIS scores, logistic regression for dental pain self-reports and anxiety scores (α = 5%). RESULTS: The mean (SD) B-ECOHIS scores at baseline and after 12 months were 17.7 (6.5) and 3.0 (4.0) in the pulpectomy group and 18.8 (7.7) and 7.9 (7.7) in the extraction group. Both treatments significantly improved OHRQoL, but tooth extraction group showed higher scores in total B-ECOHIS (p < .001) and most domains, indicating lower OHRQoL. Furthermore, higher anxiety levels were reported for dental extraction compared to pulpectomy (OR = 2.52; p = .008). CONCLUSION: Pulpectomy resulted in an improved OHRQoL scores after 12 months when compared to tooth extraction and should be considered as the treatment of choice for necrotic primary molars.

AIM: To compare the clinical and radiographically mixture of zinc oxide with Aloe vera, Curcumin and neem as an obturating material for pulpectomy. MATERIALS AND METHODS: The study comprised of age group 4-8 years children requiring endodontic treatment for at least a single primary molar tooth. Sixty primary molar teeth from 43 children were divided equally and randomly into four study groups. The materials used for obturation were zinc oxide powder (ZnO) and Eugenol (ZOE) (group I), ZnO and Aloe vera Gel (group II), ZnO and Curcumin Powder (group III), ZnO and neem extract (group IV). They were evaluated clinically and radiographically at immediate postoperative and then at 1-, 3-, 6-, and 9-month intervals. RESULTS: At the end of 9 months, the Chi-square test revealed 100% success rate for recovery of pain in group I and III, 66.66% in group II and 93.3% in group IV. The success rates for absence of abscess and for periradicular radiolucency in group I, III, and group IV were 100% and 66.6% for group II. The success rate for periapical radiolucency in group I and group III was 100%, in group II 66.6% and in group IV 93.35%. The success rate for all the groups shows 100% success in terms of pathological root resorption. CONCLUSION: Zinc oxide eugenol has proven to be the best obturating material. ZnO with Aloe vera showed a success rate which is significantly lower than the other medicaments. ZnO with Curcumin and ZnO with neem had shown promising clinical and radiographical results. CLINICAL SIGNIFICANCE: ZnO with Curcumin and ZnO with neem can be used as a root canal filling material in primary teeth with further follow-up studies.

OBJECTIVES: The complex root canal anatomy of primary teeth keeps it very tricky to attain appropriate cleansing by biomechanical instrumentation, so obtaining an obturating material with excellent antimicrobial properties is a challenge in current clinical pulpectomy practice. So, this study aimed to assess the clinical and radiographic performance of zinc oxide-ozonated olive oil as a primary root canal filling material. MATERIALS AND METHODS: Ninety non-vital primary molars in children ranging from 4 to 8 years were allocated into three groups in which root canals were filled with zinc oxide-ozonated olive oil, zinc oxide-olive oil, and zinc oxide-eugenol (ZOE) according to each group after pulpectomy procedure. Clinical and radiographic evaluations were done at 3-, 6-, and 12-month follow-up periods. Statistical analysis was performed for the collected data. RESULTS: All study groups showed a significant improvement regarding clinical signs and symptoms during follow-up periods. Ozonated-olive oil group revealed a significant increase in furcation radiodensity and a decrease in periodontal ligament space at 3-, 6-, and 12-month follow-up intervals compared to other groups. CONCLUSION: Zinc oxide-ozonated olive oil and zinc oxide-olive oil paste had shown good clinical and radiographic success for primary teeth pulpectomy. CLINICAL RELEVANCE: The intricate torturous primary root canal anatomy, in addition to the child's negative behavior, interferes with the complete debridement, so the long-lasting antibacterial effect of the primary root canal filling material aids in the pulpectomy success.

PURPOSE: The aim of this review was to compare the currently available root canal filling materials for primary teeth to zinc oxide eugenol (ZOE) to find a suitable alternative. The search question was: which root canal filling materials used in pulpectomy for primary teeth give better clinical and radiographic success rates than ZOE? METHODS: A systematic search was conducted using five databases, namely Cochrane central register of controlled trials (CENTRAL), MEDLINE via PubMed, Science Direct, Scopus and EBSCOhost using a selection of "MeSH terms". The "Modified Jadad Scale" was used for the methodology assessment of the included studies. RESULTS: Out of 480 articles identified in the initial search, 8 articles met all the inclusion criteria. The results showed that, compared to ZOE, ZOE with calcium hydroxide and iodoform had better clinical and radiographic success rates, a resorption rate similar to that of the roots, faster resorption of extruded particles and a maximum decrease in the size of pre-operative inter-radicular radiolucencies. CONCLUSION: Numerous materials, proposed and used by clinicians in root canal filling in primary teeth, can be recommended as alternatives to ZOE. However, none of them could be the ideal material in primary teeth. Thus, more high-quality well-designed randomised clinical trials are required to develop more high-performing materials.

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.

BACKGROUND: Endodontic treatment of primary molars represents one of the challenges in pediatric dentistry. There is a lack of consensus in the literature about the endodontic techniques and filling paste for primary teeth with pulp necrosis. AIM: To compare the effectiveness of the LSTR technique (lesion sterilization and tissue repair) with CTZ paste (chloramphenicol, tetracycline, zinc oxide and eugenol) and pulpectomy with ZOE paste (zinc oxide and eugenol) in the treatment of primary molars with pulp necrosis. DESIGN: Eighty-eight primary molars with pulp necrosis from 70 children between the ages of 3 and 8 years were included. The teeth were randomized to the LSTR with CTZ paste group or pulpectomy with ZOE paste group. Clinical and radiographic evaluations were performed at 18, 24, 30 and 36 months. RESULTS: At 36 months, clinical success was 86.4% in LSTR with CTZ paste and 90.9% in pulpectomy with ZOE paste (p = .45). Radiographic success was 43.2% in both groups (p = 1.00). The overall success was 40.9% in LSTR with CTZ paste and 43.2% in pulpectomy with ZOE paste (p = 1.00). CONCLUSION: After 36 months of evaluation, the effectiveness of the LSTR technique with CTZ paste and pulpectomy with ZOE paste was similar for the treatment of primary molars with pulp necrosis.

BACKGROUND: Pulpotomy has been successfully performed in immature and mature permanent teeth with irreversible pulpitis but rarely in primary teeth. AIM: To evaluate the outcomes of iRoot BP Plus pulpotomy and Vitapex pulpectomy in primary molars with irreversible pulpitis. DESIGN: We selected 130 primary molars of 99 patients, aged 3-7 years, diagnosed with irreversible pulpitis with coronal pulp tissue and treated with iRoot BP Plus pulpotomy or Vitapex pulpectomy (median follow-up period: 18 months). They were divided into the pulpotomy (n = 88) and pulpectomy (n = 42) groups according to treatment procedure. The pulpotomy group was further divided into asymptomatic (n = 46) and symptomatic (n = 42) subgroups according to preoperative symptoms. The chi-squared test and Cox regression were performed to analyze the outcomes. RESULTS: Clinical and radiographic success rates were significantly higher in the pulpotomy group (98.9% and 95.5%) than in the pulpectomy group (88.1% and 54.8%) and did not differ significantly between asymptomatic and symptomatic pulpotomy subgroups. CONCLUSION: Irreversible pulpitis of primary molars with coronal pulp tissue can be successfully treated with iRoot BP Plus pulpotomy. Early intraradicular resorption of materials is the main adverse outcome of Vitapex pulpectomy.

OBJECTIVES: The objective of this study was to analyze the success of primary molar pulpectomy with a minimum of 1 year and up to 4 years follow-up with focus on the treatment setting (general anesthesia, sedation, local anesthesia alone). METHOD AND MATERIALS: Data were retrieved from 92 patients' records between 2012 and 2020. The pulpectomy treatment using calcium-hydroxide/iodoform paste was performed under general anesthesia (n = 45), nitrous oxide sedation (n = 21), or local anesthesia alone (n = 39). Bivariate and multivariate analyses were performed. RESULTS: The overall success of pulpectomy was 59.5% 4 years post-treatment. The 4-years clinical success rate was clinically relevantly higher under general anesthesia (78.6% vs 57.1% under nitrous oxide sedation, 43.8% with local anesthesia only) and in the mandibular arch (70.8% vs 38.5% in the maxillary arch). This could be related to the strict case selection under sedation and especially general anesthesia. Despite statistically significant differences in the bivariate analysis for most outcomes and follow-up periods, this was not the case in multivariate regression. CONCLUSION: Pulpectomy performed in primary molars offers a successful long-term treatment option especially with a strict case selection as under general anesthesia.

AIM: The aim of this non-inferiority randomized clinical trial was to compare the efficacy of an iodoform-based paste (Guedes-Pinto -(GP)) as a filling material in pulpectomies of primary teeth, and a standard material composed by calcium hydroxide and iodoform (CaOH/Iodof paste; Vitapex® ). DESIGN: A total of 104 teeth from 61 children (3-8 years old) were randomly allocated to two groups according to filling materials. Children were followed up for 24 months. The primary endpoint was the treatment success rate evaluated through clinical and radiographic examinations at follow-up, and the secondary outcome was the analysis of the canal filling quality. Differences in the proportion of treatment success was calculated based on 95% confidence intervals (95% CI) and with the Miettinen and Nurminen method in the intention-to-treat population, considering a -20% of the non-inferiority limit. RESULTS: From 104 randomized teeth, 102 were followed up after 24 months (attrition rate of 1.9%). The success rate of teeth treated with the GP paste was 86.8% (95% CI: 69.9-94.9) and 78.4% (95% CI: 61.8-89.1) with the CaOH/Iodof paste. Consequently, a non-inferiority of the GP paste was observed when compared to the CaOH/Iodof paste (P < .001). CONCLUSION: The GP paste has a non-inferior success rate than the CaOH/Iodof paste used as filling material for pulpectomy in primary teeth.

Introdução: O estabelecimento do comprimento de trabalho (CT) é uma etapa fundamental para o sucesso do tratamento endodôntico, principalmente na dentição decídua. O exame radiográfico é um dos principais meios de definir o CT. A mensuração desse comprimento também pode ser obtida por meio de dispositivos eletrônicos. Objetivo: Revisar a literatura acerca da concordância entre a medida de CT por radiografia e localizadores eletrônicos foraminais (LEFs) na dentição decídua. Metodologia: A busca bibliográfica foi realizada nas bases de dados PubMed, Cochrane Library e BVS, seguindo uma estratégia de combinação de palavras-chave, filtrando apenas pesquisas clínicas. A seleção dos artigos foi realizada em duas etapas: através da leitura dos títulos e resumos e, em seguida, por meio da obtenção e leitura dos artigos completos selecionados. Resultados: sete artigos foram selecionados, publicados entre 2011 e 2020. Todos foram analisados quanto à qualidade metodológica e à caracterização como tamanho da amostra, objetivo, metodologia, resultados e conclusão. Todos possuíam os dados necessários para contemplar o objetivo desta pesquisa. O uso dos LEFs mostrou-se tão preciso quanto o método radiográfico (n=6), e, em um estudo, o método eletrônico foi superior ao radiográfico para determinação do CT. Conclusão: O método eletrônico possui eficácia na determinação do CT durante o tratamento endodôntico de dentes decíduos sendo comparável ao radiográfico.
Introduction: To establish the working length (CT) is a fundamental step toward the suc-cess of endodontic treatment. Also, the radiographic examination is one of the most important means of determining CT. This length can also be measured by electronic devic-es. Objective: To review the literature on the agreement between the CT measurement by radiography and electronic foraminal locators (LEF) in the primary dentition. Methodology: A bibliographic search was performed on PubMed, Cochrane Library, and BVS, using a keyword combination strategy and filtering only clinical research. The selection of the articles occurred in two stages: by reading the titles and abstracts, and by obtaining and reading the selected full articles. Results: Seven articles, published between 2011 and 2020, were selected and analyzed for methodological quality and characterized for sample size, objectives, methodology, results, and conclusion. They had the essential data to contemplate the purpose of this research. The use of LEF proved to be as accurate as of the radiographic method (n=6), and in one study, the electronic method was superior to the radiographic method for determining TC. Conclusion: The electronic method is effective in determining the CT during the endodontic treatment of primary teeth and is comparable to the radiographic one.
