RESUMEN

One of the most important factors that determine the success of pulpectomy in primary teeth is the root canal filling material used. This systematic review is an update on the success rates of various materials used for obturation in primary teeth. An electronic search was carried out in the PubMed, Scopus, Web of Science, and Cochrane Library databases with the preset inclusion and exclusion criteria. Only randomized or quasi-randomized clinical and controlled trials with a minimum follow-up of 12 months were included for analysis. Nine articles were considered potentially eligible for inclusion in this review. All the included trials had zinc oxide-eugenol (ZOE) cement as a control group. The time span of the included trials extended from 12 to 30 months. Only 2 trials were at low risk of bias. Evidence to support the success rates of obturating materials used in primary teeth is scarce, which necessitates further highquality randomized controlled clinical trials with regard to this issue.

RESUMEN

Background: Various root canal filling materials are used to preserve pulp tissue involved carious the primary tooth. A single material that fulfills all the requirements of an ideal root canal filling material for primary teeth is yet unavailable. Hence, this study was initiated to evaluate clinically and radiographically, the efficacy of two obturating materials - zinc oxide eugenol (ZOE) and zinc oxide mixed with Neem oil (ZON) for 12 months. Aims: To assess the success rate of a mixture of zinc oxide and neem oil in comparison to zinc oxide-eugenol paste, as an obturating material in primary molars. To compare the efficacy of ZON as an obturating material at the various time interval of 3, 6, 9, and 12 months postoperatively. Materials and methods: This split-mouth, double-blind study was performed on 24 children aged 5-7 years, who presented with bilaterally infected primary molars. Total 48 infected primary molars were divided into two groups for pulpectomy followed by obturation with ZOE and ZON, respectively. Randomization with the chit-pick method, for the control and experimental drug, was performed. A follow-up for 12 months was performed. The Chi-square test was used for inter-group comparison and the Z test was used for the analysis of data over a period of time. Results: Overall clinical findings in this study revealed 91.7% results in ZOE compared with 100% results in the ZON group. The radiographical findings revealed 91.7% results in ZOE compared with 100% success in the ZON group. Conclusion: ZON demonstrated excellent effectiveness as an obturating material in the 12-month follow-up period as compared to ZOE in primary teeth. The efficacy elicited in this study could be a basis to recommend ZON as herbal alternative obturation material.

RESUMEN

National identity programs like Aadhaar in India can play an unique role in identification of an individual and has numerous beneficial applications for the government and the citizens. The biometric records of finger prints and iris provided in the database can be useful for the forensic purpose. In unfortunate incidence of disasters, accidents, and criminal cases such as severe burnings, the identification of the victims is possible through dental profiling where fingerprint matching is not possible. Endodontic treatment includes the radiography for diagnosis of the lesion, during working length determination, obturation, and various other procedures. The variations in tooth anatomy and morphology, post-endo restorations, root canal fillings, and sometimes, endodontic mishaps are recorded in these radiographs. This record can play an important role in identification of a person in case of unfortunate happenings. So, it is suggested to include dental profiling in National Identification programs, and the purpose of this article is to highlight the role of root canal procedures in dental profiling.

RESUMEN

Background: Zinc oxide eugenol(ZOE) has long been the material of choice for obturating primary teeth,but it is resistant to resorption, might result in a deflected successor and has limited antibacterial efficacy. Curcuminpossessesanti-inflammatory and antimicrobialproperties which can be implied by its use as obturating material in primary teeth. Objective: To evaluate and compare the efficacy of Curcumin Gel mixed Endoflas powderand Zinc oxide eugenol as obturating materials in primary molars. Material and methods: A total of 30 primary molars indicated for pulpectomy were selected from 4-9-yearold children and divided into two equal groups based on the obturating material used. Group 1- Curcumin Gel mixed Endoflas powder(CGE) and Group 2- Zinc oxide eugenol(ZOE). The efficacy of these obturation materials was evaluatedboth clinically and radiographically. Follow-up was done after 1, 3 and 6months to evaluate clinical and radiographical success rates. The results were subjected to statistical analysis using SPSS software version 21 using chisquare test. Results: At the end of the 6th month follow-up,there was 93.3% clinical success in Group 1 compared with 86.6% success in Group 2. Whereas, radiographically success reported was 100% with Group 1 and 93.3% with Group 2. The difference in the radiographic success rate between the two Groups was statistically significant (P < 0.05). Conclusion: Based on the present study results, Curcumin Gel mixed Endoflas powder can be considered as an alternative obturation material for treating deciduous molars with extensive involvement of pulp and periradicular tissues.(AU)

Fundamentação: O óxido de zinco eugenol (OZE) há muito tempo é o material de escolha para a obturação de dentes decíduos, mas é resistente à reabsorção, podendo resultar em um dente permanente desviado e tem eficácia antibacteriana limitada. A curcumina possui propriedades anti-inflamatórias e antimicrobianas que podem indicar seu emprego como material obturador em dentes decíduos. Objetivo: Avaliar e comparar a eficácia da pasta de curcumina Endoflas e do óxido de zinco eugenol como materiais obturadores em molares decíduos. Material e métodos: Um total de 30 molares decíduos indicados para pulpectomia foram selecionados entre crianças de 4 a 9 anos e divididos em dois grupos iguais, com base no material obturador utilizado. Grupo 1 - pasta de curcumina Endoflas (CGE) e Grupo 2- óxido de zinco eugenol (ZOE). A eficácia desses materiais de obturação foi avaliada clinicamente e radiograficamente. O acompanhamento foi realizado após 1, 3 e 6 meses para avaliar as taxas de sucesso clínico e radiográfico. Os resultados foram submetidos à análise estatística no software SPSS versão 21, utilizando o teste quiquadrado. Resultados: No final do sexto mês de acompanhamento, houve 93,3% de sucesso clínico no Grupo 1 em comparação com 86,6% de sucesso no Grupo 2. Considerando que, o sucesso radiográfico relatado foi de 100% no Grupo 1 e 93,3% no Grupo 2. A diferença na taxa de sucesso radiográfico entre os dois grupos foi estatisticamente significante (P < 0,05). Conclusão: Com base nos resultados do presente estudo, a pasta de curcumina Endoflas pode ser considerada como um material de obturação alternativo para o tratamento de molares decíduos com amplo envolvimento de polpa e tecidos perirradiculares (AU)

RESUMEN

INTRODUCTION: Preservation of primary tooth with non-vital pulp has been a major problem for pediatric dentist. In such cases, the preferred treatment modality is pulpectomy. The objective of pulpectomy is complete removal of necrotic and irreversibly infected pulp of an affected tooth but, in spite of chemomechanical preparation and copious irrigation of canal, there are chances of failure of pulp therapy due to the entrapped micro organisms in the canal space owing to the tortuous and complex nature of the root canal system and change in their morphology with root resorption. Thus, for optimal success of endodontic treatment, obturating material with antimicrobial properties is advocated in deciduous teeth. AIM: The aim of the study was to assess the antimicrobial efficacy of different obturating materials used in pediatric dentistry. MATERIALS AND METHODS: In the present study, antimicrobial efficacy of endoflas, Zinc Oxide Eugenol (ZOE), calcium hydroxide with chlorhexidine, calcium hydroxide with iodoform and distilled water, metapex and saline as control were assessed and compared with each other. The antimicrobial efficacy of obturating materials was evaluated against E. faecalis (ATCC 29212) by agar diffusion method. The statistical analysis was done using SPSS Version 15.0. The Analysis of Variance (ANOVA) and Post-Hoc Tests (Tukey-HSD) were performed to reveal the statistical significance. RESULTS: Intergroup comparison at 24 hours (Tukey's test) revealed significant difference amongst all the groups. Endoflas had significantly higher zone of inhibition as compared to all the other groups except group treated with ZOE (p-value <0.001). CONCLUSION: The antimicrobial activity of obturating materials according to results obtained from the present study can be summarized as follows: Endoflas > ZOE >Calcium hydroxide + Chlorhexidine > Calcium hydroxide + Iodoform +Distilled water ~ Metapex > Saline.
