“…For treatment of primary teeth, endodontic filling materials must meet certain basic requirements, such as biocompatibility to peri-radicular tissues, slow resorption (to follow primary teeth physiological resorption), antimicrobial characteristics, and physicochemical properties, including radiopacity and flow. 3,4,5,6 Moreover, the success of endodontic treatment of deciduous teeth depends on the quality of root canal filling, which is expected to present a complete fill of the root canal system without extrusion to the periapical tissues. 7,8 Among different options used globally, Vitapex ® (Neo International, Federal Way, USA), a premix of calcium hydroxide and iodoform, is considered the gold standard in filling materials for primary teeth, with considerable success rates.…”

In this study, we evaluated the physicochemical properties (PCP; radiopacity, flow, pH, and solubility) and the quality of root canal filling provided by an experimental industrialized paste (EP), with the same active ingredients as those of the Guedes Pinto paste, compared with the Vitapex ® paste. PCP were analyzed according to the ANSI/ADA laboratory testing methods for endodontic filling and sealing materials. To analyze filling capacity, 120 artificial primary teeth (60 maxillary incisors [MIs] and 60 mandibulary molars [MMs]) were endodontically treated. The teeth were divided into eight groups based on the dental group (MIs or MMs), filling material (Vitapex ® or EP), and insertion method (syringe or lentulo). The Image J ® software was used to analyze the initial an final digital radiographies of each tooth, measuring and comparing root canal and void areas. The percentage of filling failure areas was obtained. Data were submitted to ANOVA and Tukey test of mean comparison. Regarding PCP, both pastes presented results according the ANSI/ADA standards.

Objetivos: Evaluar in vitro la acción antimicrobiana de las pastas GuedesPinto modificadas con Diprogenta® y con Otosporin®, comparándolas con la pasta Guedes-Pinto convencional. Materiales y métodos: Se evaluó la acción antimicrobiana de las pastas Guedes Pinto contra cepas aisladas de los siguientes microbios: Streptococcus mutans ATCC 25175 Staphylococcus aureus ATCC 25923, Enterococcus faecalis - ATCC 29212, Pseudomonas aeruginosa - ATCC 4116, Candida albicans ATCC 10231. Se empleó la técnica de difusión en agar por el método de pocillo y en triplicado, utilizando el digluconato de clorexidina al 0,12% como control positivo y solución salina como control negativo. Se transfirió 2 mL del inóculo producido de cada microbio a 100mL de agar fundido a 45ºC, dispensando la mezcla en 30 placas de petri. Las placas fueron mantenidas a temperatura ambiente por dos horas y luego incubadas a 35ºC por 24 y 48 horas. La lectura de los resultados fue sometida al Análisis de varianza de un factor y Test de Tukey para comparaciones múltiples. Resultados: La pasta Guedes-Pinto Convencional formó los mayores halos de inhibición para la mayoría de los microbios, con excepción de Candida albicans, donde ninguna de las sustancias produjo efecto y de la Pseudomonas aeruginosa, para la cual la pasta modificada con Diprogenta® obtuvo mejores resultados, sin diferencia estadística entre ellas. La pasta Diprogenta® presentó mejores resultados que la pasta Otosporin® para todos los demás microorganismos y esto ultimo no formó halo de inhibición para Enterococcus faecalis. Conclusión: La utilización de sustitutos de Rifocort® parece tener un potencial antimicrobiano efectivo contra los principales microbios encontrados en los canales radiculares.

“…Guedes-Pinto paste, composed of iodoform, camphorated paramonochlorophenol and Rifocort ® (rifamycin ointment), was once the most used filling material in Brazilian educational institutions. 11,12 Classical pulpectomy with debridement and modeling of root canals has been the gold standard treatment for primary teeth with irreversible pulp inflammation or pulp necrosis. 1 Clinical and radiographic success, after 12 months, with this material was found to be 100% and 97.1%, respectively.…”

Cost analysis of endodontic treatment in primary teeth: results from a randomized clinical trial

et al. 2021

View full text Add to dashboard Cite

This study compared the cost of endodontic treatment in primary teeth involving a technique that does not require root canal instrumentation using antibiotic paste (CTZ) with that of the instrumented technique using iodoform paste (GP). This study is part of a randomized, controlled, parallel arm, noninferiority, 1:1 allocation, blinded (patient) multioperator study of 52 primary incisors of children aged 3 to 6 years with caries lesion and pulp involvement. Each technique was performed according to the creators' descriptions. The cost was assessed by analyzing the costs of capital, dental supplies, and professional labor according to the time taken to perform the procedure and the CHEERS guidelines were used to report the cost assessment. Endodontic treatment with CTZ had a 58.33% lower execution cost than GP (US$6.73 and US$16.15, respectively). The t-test showed significant differences between groups regarding treatment time and total cost (p < 0.0001). The CTZ technique seems to be more economically viable than GP for endodontic treatment of primary teeth, requiring a shorter treatment time and lower costs.

Variability in the proportion of components of iodoform-based Guedes-Pinto paste mixed by dental students and pediatric dentists

Abstract: The proportion of GPP was similar in all the groups, allowing us to conclude that ideal GPP proportion, based on the entire group mean, was 23.8% of Rifocort® ; 7.0% of camphorated PMCC; and 69.2% of iodoform.
