Aim. Root canal filling materials have the tendency to inhibit adhesion of resin-based composites. This study was aimed at evaluating the effect of root canal filling materials and their solvents on the shear bond strength (SBS) of resin composite with the primary tooth dentin. Methods and Materials. Seventy-two intact anterior primary teeth were selected. Smooth dentinal surfaces were prepared to a minimum diameter of 3 mm and thickness of 1.5–2.0 mm. The samples were equally divided into six groups ( n = 12 ). In group 1: control group, no root filling material; in group 2: Metapex, no solvent; in group 3: Metapex+ethanol solvent; in group 4: ZOE, no solvent; in group 5: ZOE+ethanol solvent; and in group 6: ZOE+orange oil solvent were applied. Then, dentin surfaces were etched, and composite restorations were placed and cured. The specimens were stored in distilled water at 37°C for 24 hours. SBS values were determined using a universal testing machine. Results. The SBS values of composite to dentin in groups 2 and 4 were significantly lower than those in the control group ( P < 0.001 ). Cleansing of the specimens with 96% ethanol after removal of Metapex significantly increased the composite-dentin bond ( P < 0.001 ). Applying ZOE, only orange oil solvent significantly increased the SBS of the composite to the primary tooth dentin ( P = 0.01 ). Conclusion. To reduce the negative effects of endodontic root filling materials on the SBS of composite and primary tooth dentin, ethanol is a suitable solvent when Metapex is used, while orange oil might be a better choice than ethanol when applying ZOE.

Abstract Introduction Pulpectomy helps in preserving a pulpally involved primary tooth by eliminating bacteria and their products and ensures hermetic seal of the root canals, so that the primary teeth can complete their function until normal exfoliation. For the success of endodontic treatment in primary teeth, the resorption of obturating material plays a vital role. The materials used for obturation in this study included zinc oxide propolis (ZOP) as a new paste, Endoflas, Metapex, and zinc oxide eugenol (ZOE). Objective To evaluate the success rate of pulpectomy of primary molars using four different root canal filling materials: ZOP as a new paste, Endoflas, Metapex, and ZOE. Materials and Methods A total of 48 primary molars were divided into four equal groups of 12 molars according to the type of root canal filling paste, that is, ZOE, Endoflas, ZOP, and Metapex. Results When Tukey’s test was applied, out of the four materials, ZOP was the most significant material as its p-value was < 0.05, whereas other materials showed nonsignificant results as their p-value was > 0.05. Conclusion Among the four groups, ZOP showed greater clinical success and its resorbability was similar to that of root.

Introdução: O processo de pulpotomia convencionalmente é feito com formocresol, porém, devido as suas características mutagênicas, novos materiais obturadores foram desenvolvidos como alternativa. Objetivo: Revisar a literatura de forma integrativa a respeito do material obturador mais adequado para pulpotomia de dentes decíduos. Metodologia: A busca ocorreu nas bases de dados Pubmed e Medline, por meio dos descritores: “child”, “children”, “primary teeth”, “tooth, deciduous”, “primary tooth”, "pulpotomy", "pediatric dentistry", "endodontics", "root canal filling materials", "materials", "material", "biodentine", "mineral trioxide aggregate", "formocresol", "formocresols", "cytotoxicity", "biocompatible materials", "biocompatibility", "radiopacity", "radiographic" e "radiography, dental". Foram incluídos ensaios clínicos, estudos retrospectivos e estudos prospectivos, publicados entre 2016 e 2021, em inglês ou português. Os critérios de exclusão foram teses, dissertações, monografias, cartas ao editor, livros e revisões de literatura. Resultados: A pesquisa resultou em 9 estudos de ambas as bases de dados, com maior prevalência de ensaios clínicos. Conclusão: O material mais recomendado para realização de pulpotomias em dentes decíduos é o Biodentine e Mineral Trioxide Aggregate, devendo a escolha ser feita de acordo com o critério do profissional e caso do paciente. É preciso que seja considerado os custos e colaboração do paciente durante o tratamento.

ABSTRACT Despite the improvement of endodontic materials, crown discoloration induced by root canal sealers remains a concerning clinical issue. The aim of this study is the measurement of the alterations in CIE L*, a*, b* chromatic parameters of tooth crowns after placement of commonly used and new-generation endodontic sealers in pulp chambers. Eighty intact, fully developed third mandibular molars were randomly assigned in five groups. Crowns were cross-sectioned from the root complex 1 mm below the cement-enamel junction. The internal axial walls of the pulp chambers were debrided and coated with endodontic sealers (Roth-811, AH-26, Guttaflow, Epiphany SE). The apical access was sealed with glass-ionomer cement. The control group was only debrided. Crowns were stored in individually marked vials in standard conditions (100% humidity, 37°C). The spectral reflectance lines were recorded with a UV-Vis spectrophotometer in the visual spectrum. The CIE L*a*b* parameters were obtained by a linked computer software before sealer placement (baseline), after one week, one, three, and six months, respectively. Statistical analysis was performed with two-way mixed ANOVA models. The level of statistical significance was set at p&lt;0.05. With the exception of the control group, experimental groups presented varying chromatic alterations. Among all experimental groups, Roth-811 sealer induced the most severe alterations in CIE L*, a*, b* chromatic parameters, during all observation periods. After root canal obturation, the clinician should be aware of the presence of remaining root canal filling materials. Thorough debridement of the pulp chamber is essential for the prevention of sealer-induced discoloration.
