Is there evidence for the use of lesion sterilization and tissue repair therapy in the endodontic treatment of primary teeth? A systematic review and meta-analyses
Clinical Oral Investigations, 2020Co-Authors: Maysa Lannes Duarte, Paula Maciel Pires, Daniele Masterson Ferreira, Andréa Vaz Braga Pintor, Aline Almeida Neves, Lucianne Cople Maia, Laura Guimarães PrimoAbstract: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; I ^2 = 0%), 12 months (RR = 0.97, 95% CI, 0.90–1.04, p = 0.34; I ^2 = 0%), and 18 months (RR = 0.89, 95% CI, 0.77–1.04, p = 0.14; I ^2 = 0%) and radiographic findings at 6 months (RR = 0.91, 95% CI, 0.78–1.06, p = 0.23; I ^2 = 9%), 12 months (RR = 0.87, 95% CI, 0.65–1.18, p = 0.38; I ^2 = 64%), and 18 months (RR = 0.84, 95% CI, 0.69–1.02, p = 0.08; I ^2 = 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.

International Journal of Paediatric Dentistry, 2012Co-Authors: Roberta Barcelos, Patricia Nivoloni Tannure, Rogerio Gleiser, Ronir Raggio Luiz, Laura Guimarães PrimoAbstract:International Journal of Paediatric Dentistry 2012; 22: 369–381 Background. The effect of smear layer (SL) removal on primary tooth Pulpectomy outcome has not been well elucidated. Aim. To determine the effect of SL removal on primary tooth Pulpectomy outcome. Methods. This is a double-blind, randomized, and controlled clinical trial. Forty-eight patients were randomly divided into SL removal (G1 = 40 teeth) or smear layer nonremoval (G2 = 42 teeth) groups. Following the chemomechanical preparation with K-files and 2.5% sodium hypochlorite (NaOCl), teeth were irrigated with either 6% citric acid and 0.9% physiologic solution (G1) or only 0.9% physiologic solution (G2). Camphorated paramonochlorophenol was used as intracanal medication. At the second appointment, 1 week after, root canals were filled with zinc oxide–eugenol paste. Clinical and radiographical baseline criteria were stipulated equally for both groups. Results. The success rate (G1 = 91.2%; G2 = 70.0%) was statistically different (P = 0.04) between the groups. In G2, the outcome was affected significantly by pulpal necrosis (P = 0.02), pre-operatory symptoms (P = 0.02), and periapical/inter-radicular radiolucency (P = 0.04). Conclusion. The Pulpectomy outcome was improved by smear layer removal. The outcome for teeth with pulpal necrosis, pre-operatory symptoms, or periapical/inter-radicular radiolucency was significantly improved by removal of the smear layer.

Ectopic eruption of permanent incisors after predecessor Pulpectomy: five cases.
General dentistry, 2011Co-Authors: Patricia Nivoloni Tannure, Roberta Barcelos, Tatiana Kelly Da Silva Fidalgo, Rogerio Gleiser, Laura Guimarães PrimoAbstract:Pulpectomy in primary teeth is a common technique that preserves teeth in the oral environment and maintains or recovers periapical tissues to a healthy condition. This article describes the ectopic eruption of permanent incisors whose primary predecessors underwent Pulpectomy using ZOE filler paste. In a group of 135 teeth that received Pulpectomy therapy due to caries, 10 primary maxillary incisors had overretention and were followed for at least 3.5 years (mean time of 4.2 years), both clinically and radiographically, until the permanent teeth erupted. The proposed treatment included extraction of the overretained primary incisors based on permanent successor eruption chronology and contralateral eruption. Seven permanent teeth erupted ectopically. Autocorrection of the permanent tooth positions was observed in five cases. It can be concluded that periodic clinical and radiographic assessments are essential to verify radicular and filling paste resorptions and to avoid overretention and any subsequent malocclusion.

Long-term outcomes of primary tooth Pulpectomy with and without smear layer removal: a randomized split-mouth clinical trial.
Pediatric Dentistry, 2011Co-Authors: Patricia Nivoloni Tannure, Roberta Barcelos, Rogerio Gleiser, Camilla Pontes Azevedo, Laura Guimarães PrimoAbstract:PURPOSE The aim of this study was to evaluate, via clinical and radiographic assessment, Pulpectomy outcomes performed on primary anterior teeth both with and without a citric acid solution to enhance smear layer removal. METHODS Patients with a matched pair of primary incisors (split-mouth design) with irreversible pulp changes were selected. A total of 36 teeth (18 children) received pulpectomies and were followed for 36 months. Pulpectomies were performed using sodium hypochlorite and saline solution as canal irrigants; during the last irrigation, the tooth was randomly selected to receive ( Group 1) or not receive (Group 2) the citric acid solution for smear layer removal. The roots were filled with ZOE paste. RESULTS Overall Pulpectomy success was 90.6%. Cases with smear layer removal were successful 82.3% of the time; those without smear layer removal, 88.2%, and there were no statistical differences (P=1.00). CONCLUSION Pulpectomy with smear layer removal in primary incisors exhibited, after 36 months, a high success rate; however, comparable results were obtained when the smear layer was not removed.

iranian endodontic journal, 2018Co-Authors: Elham Farokhgisour, Masoud Parirokh, Marjan Kheirmand Parizi, Nouzar Nakhaee, Masoumeh AminizadehAbstract:Introduction: The aim of this study was to compare post-operative pain following one-visit Pulpectomy and placing stainless steel crown (SSC), with two-visit treatment (performing Pulpectomy at the first visit followed by placing SSC at the next visit one week later) in vital pulp of primary molars with carious involvement. Methods and Materials: In this randomized clinical trial, 100 children aged 6-12 years with a carious primary molar tooth in need of Pulpectomy were randomly divided into two groups of 50 each. In one-visit group, Pulpectomy and placement of SSC were carried out at the same appointment. In two-visit group, Pulpectomy of root canals was carried out at the first visit and placement of SSC was performed at the second visit one week after the first appointment. Post-operative pain was recorded using visual analogue scale (VAS) during one week after each treatment visit. Results: No significant difference was found in the mean age and gender distribution between the two groups ( P ˃0.05 for both comparisons). Findings revealed that in the two-visit (Pulpectomy) group during first three days and 4-7 days after the first treatment appointment, pain felt by the children was significantly lower than that felt by the one-visit group at the same time period ( P ˂0.0001 for both comparisons). Moreover, children in two-visit (Pulpectomy) group consumed significantly lower amount of analgesics than those in the one-visit group ( P <0.0001). Conclusion: No significant difference was found between pain felt by children during the first three days following one-visit Pulpectomy and placement of SSC at the same appointment. Therefore, one-visit treatment of vital primary tooth is recommended. Keywords: Children; One-Visit; Pain; Postoperative; Primary Teeth; Pulpectomy; Two-Visit

zinc oxide eugenol paste retained in gingival mucosa after primary teeth Pulpectomy
European journal of paediatric dentistry : official journal of European Academy of Paediatric Dentistry, 2010Co-Authors: Nivoloni Tannure P, Roberta Barcelos, J Farinhas, Guimaraes Primo LAbstract:AIM Long-term follow-up evaluations of Pulpectomy in primary teeth have revealed retention of ZOE filling particles in the periapical area even after root resorption. CASE REPORT This paper reports a case of a child submitted to Pulpectomy with ZOE paste in primary teeth. After 28 months, the filling particles remained, having migrated to the alveolar bone from the gingival vestibular mucosa during permanent dentition eruption. Aesthetics required periodontal surgical removal of the paste particles. Primary teeth submitted to Pulpectomy should be evaluated carefully both clinically and radiographically to verify radicular and ZOE filling paste resorption. The consequences of retained particles during permanent dentition eruption are unknown.
