BACKGROUND To avoid untoward changes when primary teeth are replaced by permanent teeth, resorption of the material used in primary teeth root canal filling should occur at the same rate as root resorption. The Aim of this study was to compare the success rates of a mixed primary root canal filling (MPRCF, ingredients: zinc oxide-eugenol [ZOE], iodoform, calcium hydroxide) to those of ZOE and V...
The diffusion of glutaraldehyde from zinc oxide and eugenol cement (ZOE) into water was measured. The egress was found to be substantial and correlated to the amount of glutaraldehyde which was incorporated initially. The percentages of the fixative which diffused from the ZOE preparations containing 2,5, or 10% glutaraldehyde were virtually identical, demonstrating that there is no restriction...
Maintaining a successfully root-treated primary molar has the advantage of preserving the natural tooth--the best possible space maintainer. The purpose of this study was to compare the success of endodontic treatment of nonvital primary molars using ZOE with that of KRI paste. Of 78 necrotic primary molars, 34 were filled with ZOE and 44 with an iodoform-containing paste (KRI). The canals were...
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 ...
OBJECTIVE To perform a systematic review in which the clinical research question for primary teeth with irreversible pulpal pathosis was "how pulpectomies with zinc oxide eugenol (ZOE) paste performed compared to other materials in their clinical and radiographic outcomes after twelve months or more follow-up period. STUDY DESIGN A literature survey of the electronic database (1950-2010) used...
This study evaluated in vitro the antibacterial activity of 4 root canal filling materials for primary teeth - zinc oxide and eugenol cement (ZOE), Calen paste thickened with zinc oxide (Calen/ZO), Sealapex sealer and EndoREZ sealer - against 5 bacterial strains commonly found in endodontic infections (Kocuria rhizophila, Enterococcus faecalis, Streptococcus mutans, Escherichia coli and Staphyl...
Despite the central role of learning in visual recognition, it is largely unknown whether visual form learning is maintained in older age. We examined whether training improved performance in both young and older adults at two key stages of visual recognition: integration of local elements and global form discrimination. We used a shape-discrimination task (concentric vs. radial patterns) in wh...
Objective To evaluate solubility, dimensional stability, filling ability and volumetric change of root-end filling materials using conventional tests and new Micro-CT-based methods. Material and Methods 7. Results The results suggested correlated or complementary data between the proposed tests. At 7 days, BIO showed higher solubility and at 30 days, showed higher volumetric change in compa...
Pulpal response of four calcium hydroxide liners, MPC 10, MPC 12, Dycal and Pulpdent were tested on primary and permanent teeth with zinc oxide and eugenol (ZOE) and silicate as controls. Responses of the pulps were evaluatedi in Rhesus monkeys, utilizing Class V cavity preparations at 3 days, 5 and 8 weeks. An equivalent number of anterior and posterior teeth were studied for all compounds. Th...
The aim of this study was to evaluate in vitro the antimicrobial activity of glass ionomer (GIC) and zinc oxide-eugenol (ZOE) cements against Candida albicans. Standardized GIC and ZOE specimens were maintained in contact with C. albicans suspension (1 x 10(6) cells/ml) at 37 degrees C for 24 h, 48 h or 7 days. A control group without any testing cement was included. After the incubation period...
