“…When used alone, Calen paste present recognized biocompatibility (23), thus the persistent inflammation observed in Calen+ZO group may be attributed to the higher concentration of zinc in the material, since zinc has the capacity to influence in the inflammatory process for reducing phagocytic capacity of macrophages and to interfere in the membrane of the lysosomes (24).…”

This study assessed the pH, radiopacity, antimicrobial effect, cytotoxicity and biocompatibility of endodontic filling materials for primary teeth. Zinc oxide eugenol (ZOE), Vitapex and Calen paste thickened with zinc oxide (ZO) were evaluated in comparison to an experimental MTA-based material. Radiopacity was tested using a graduated aluminum stepwedge with a digital sensor (n=5). The materials pH was recorded at 1, 4, 12 h; 1, 3, 7, 15 and 30 days (n=5). Direct contact test was used to assess the antimicrobial efficacy against Enterococcus faecalis after 1, 4, 12, 24 h (n=5). Cytotoxicity assay used MTT test for cell viability after incubation for 1, 3 and 7 days (n=5). For biocompatibility test, Wistar rats had received implants containing each material (n=5). The biopsied tissues were histologically analyzed after 15, 30 and 60 days. The results of radiopacity, pH, antimicrobial capacity and cytotoxicity were analyzed using ANOVA and Tukey tests. The histological data were submitted to Kruskal-Wallis test. The experimental material presented the lowest radiopacity (3.28 mm Al) and had a pH>12.0 throughout the test period. The experimental material showed the highest antibacterial effect, killing over 99.97% bacteria in 4 h. Vitapex presented the highest cell viability. Initially, biocompatibility test showed moderate to severe inflammation in all groups. After 60 days, Calen+ZO group showed moderate inflammation, while the others showed predominantly mild inflammatory reaction. The present results demonstrated that the experimental MTA-based material exhibited satisfactory behavior regarding the studied properties. Additional in vivo studies are necessary for a better evaluation of the material. Physicochemical and Biological Evaluation of Endodontic Filling M a t e r i a l s f o r P r i m a r y Te e t h

“…Regardless of the root filling material used, an immediate post‐operative periapical radiograph should be taken for two reasons: evaluate the quality of the fill and consider prescribing antibiotics in cases of excessive overfill; and provide a baseline for assessing and comparing the success of the root canal treatment in follow‐up visits. Previous endodontic research in primary teeth focused on finding the ideal root canal filling (Table ); however, newer studies examining other aspects of the pulpectomy procedure have recently been published in the pediatric dental literature. Among the many new exciting areas of study are the use of antibacterial medicaments, irrigating solutions, and removal of the smear layer during canal preparation .…”

Premature loss of primary teeth can lead to malocclusion and/or to esthetic, phonetic, or functional problems. Maintaining the integrity and health of the oral tissues is the primary objective of pulp treatment. It is important to attempt to preserve pulp vitality whenever possible; however, when this is not feasible, the pulp can be entirely eliminated without significantly compromising the function of the tooth. This article provides a concise review of the normal histological characteristics of the primary pulp and briefly describes the dentinogenesis process and the factors affecting the dentin-pulp complex response to stimuli. Finally, the biological basis and rationale for the various modalities of pulpal treatment for the primary dentition are discussed and data on the success rates for the different treatment is presented.

“…9 There are many available filling materials for this purpose; however, none of them possesses all the ideally required characteristics and properties. 10 In the consulted literature, there is no randomized controlled clinical trial, with adequate methodology, conducted to evaluate the performance of root filling materials after smear layer removal in pulpectomy of primary teeth. Therefore, this study aimed to investigate the clinical and radiographic performance of pulpectomies using 1) iodoform paste and 2) calcium hydroxide/zinc oxide (Calen ® /ZO) paste (thickened by the manufacturer) in primary teeth with irreversible pulpitis or pulp necrosis caused by dental caries or trauma.…”

This study evaluated clinical and radiographic twelve-month outcomes of root canal treatments (CT) with smear layer removal, performed in primary teeth, using two different root canal filling materials. Pulpectomy was performed on 27 primary teeth with necrosis or irreversible pulpitis, caused by dental caries or trauma, in 23 children (2-7 years old). A single trained operator performed the CT in a single visit in cases without periapical or interradicular radiolucency (PIR) or in multiple visits in cases with PIR. Participants were selected based on specific inclusion and exclusion criteria, and randomly allocated into two groups: Group 1 (G1)-iodoform paste (iodoform + camphorated parachlorophenol + ointment comprising prednisolone acetate 5.0 mg and rifamycin 1.5 mg); Group 2 (G2)-Calen ® /ZO paste. Treated teeth were restored with composite resin immediately after the root canal filling. The outcomes were evaluated clinically and radiographically according to specific criteria. Two blinded and standardized evaluators assessed the radiographic outcomes. We used descriptive analyses due to the small sample size. CTs were performed due to caries lesions in 70.4% of the cases and due to trauma in 29.6%. Only one tooth of G1 was unsuccessful; hence, pulpectomy performance in both groups was not influenced by the filling material, nor by any other analyzed variable. The level of the root canal filling was better in the Calen ® /ZO group. The clinical and radiographic twelve-month outcomes indicated successful treatment, independently of the root filling material used.

Eighteen-month clinical and radiographic evaluation of two root canal-filling materials in primary teeth with pulp necrosis secondary to trauma

Abstract: Our results showed the clinical and radiographic outcomes for Calen(®) /ZO to be equal to those for ZOE after 18months, suggesting that both materials can be indicated for obturating primary teeth with pulp necrosis after trauma.
