ABSTRACT Aim The purpose of this study is to compare the efficacy of calcium hydroxide and zinc oxide eugenol as a root canal filling material in primary teeth using endodontic pressure syringe system. Materials and methods A total of 40 primary mandibular molars were selected and divided into two groups-group I (calcium hydroxide was used as root canal filling material) and group II (zinc oxide eugenol used as canal filling material). Clinical review was undertaken at 1, 3, 6 and 9 months interval for evaluating pain, tenderness, mobility and any other sign of pathology. Radiographic examination was done at interval of 3, 6 and 9 months for the evaluation of any change in the radiolucency around the apices and inter-radicular space. Resorption of root and filling material was also assessed. Results Reduction in the clinical symptoms were noted in both groups (p < 0.01). All the 20 cases in group I demonstrated a decrease in size of radiolucency. However in group II, an increase in radiolucency was observed in 2 teeth at 3 months radiographic examination. Further no decrease in the size of radiolucency was noticed at subsequent follow-up visits. Complete resorption of overfilled material was observed at the 3 months radiographic examination for group I whereas partial resorption of overfilled material was seen at 6 months radiographic examination for group II. Conclusion The findings of the present study indicate that calcium hydroxide could be used exclusively or as an alternative to zinc oxide eugenol as a root canal filling material for the primary teeth.

Pulpectomy in deciduous teeth involves endodontic access opening, root canal debridement and obturation with an appropriate filling material. EndoREZ (ER) is the urethane dimethacrylate-based filler, which can be used for root canal obturation in permanent and primary teeth. This observation aimed to evaluate the behavior of the ER as a filler in root canals of two primary molars after the physiological resorption process using the scanning electron microscopy (SEM) and micro-computed tomography (µCT) in second lower molars after their natural exfoliation. The SEM analysis revealed a non-uniform, porous and lacunary structure of ER, visually similar to the resorbed surface of the dentine. The µCT observations demonstrated the differences in the resorption level of the root and material surfaces. The preliminary observations suggest that ER is resorbed faster than root tissues and can therefore be a suitable material for the root canal filling in primary teeth. However, more investigations are needed to support these preliminary findings.

Inadequate treatment of endodontic infections in primary teeth results in a loss of &#1072; deciduous tooth or abnormality in the development of hard dental tissues of the permanent successor. The main goal is to maintain the integrity and health of the primary tooth until their physiological exfoliation. The success of the endodontic treatment depends on the antimicrobial activity of the root canal filling material that contributes to the elimination or reduction of the microbial infection of the root canal system. The aim of this article is to systematically review the contemporary scientific literature concerning the root canal filling materials used in primary teeth. A critical evaluation of the antimicrobial activity, as well as the advantages and disadvantages of the investigated materials, has been made. Knowledge of the composition and characteristics of the available obturating materials is a useful advantage to dentists to address the functional problems associated with endodontic infections in very young patients. Future studies should also seek and compare the long-term effects of the use of traditional and alternative intracanal materials.

Background and objectives: Since complete debridement of the root canals of the primary teeth is not practically possible due to the highly variable root canal anatomy, success of the endodontic therapy depends partly on the use of antibacterial irrigating agents and root canal filling materials. Recent literature indicates that anaerobes comprise a majority of the bacteria in necrotic root canals of primary teeth. The study determined the antibacterial effectiveness of four root canal filling materials namely Calcium hydroxide,Zinc oxide eugenol, Vitapex and Metapex against microbial specimens obtained directly from necrotic root canals of primary teeth. Method: Microbial specimens were collected using sterile paper points, from 15 primary maxillary and mandibular posterior teeth of randomly selected children in the age group of 4-10 years with infected non vital primary teeth, requiring pulpectomy procedure. The microbial specimens collected were subjected to microbiological analysis and the antimicrobial potential of root canal filling materials were tested using Agar diffusion technique. Results: were statistically analyzed using one-way ANOVA. Facultative/Aerobic organisms were isolated in all the cases, anaerobic organisms were isolated in 80% of the cases, and Candida albicans was isolated in 1 case. ZOE showed superior inhibitory activity against most of the organisms isolated followed by Vitapex, Calcium hydroxide and Metapex in descending order.Conclusion: Our data may be useful as a guide for relative antimicrobial effectiveness or non-effectiveness of the materials employed. In vivo studies are required to state the specific antimicrobial activity and merits and demerits of any of the test filling material.

Abstract Background Three-dimensional obturation of the root canal system is mandatory for a successful root canal treatment. Using a filling material with optimal properties may enable the root canal to be sealed well and therefore obtain the desired obturation. Objective To develop a new injectable paste endodontic filling material using calcium phosphate powder and a styrene–butadiene emulsion polymer. Methods The powder phase comprised an equivalent molar ratio of tetracalcium phosphate, anhydrous dicalcium phosphate, bismuth oxide, and calcium chloride. The liquid phase comprised a styrene–butadiene rubber emulsion in distilled water. The powder and the liquid were mixed to achieve a paste consistency. The paste was subjected to various tests including flow, setting time, dimensional change, solubility, and radiopacity to indicate its suitability as a root canal filling material. All these tests were conducted according to the American National Standards Institute–American Dental Association for endodontic sealing materials. After passing these tests, the paste was submitted to an injectability test. Results The material showed acceptable flowability with 19.1 ± 1.3 min setting time and 0.61 ± 0.16% shrinkage after 30 days of storage. We found the highest solubility at 24 h (6.62 ± 0.58%), then the solubility decreased to 1.09 ± 0.08% within 3 days. The material was more radiopaque than a 3 mm step on an aluminum wedge. Furthermore, the material showed good injectability of 93.67 ± 1.80%. Conclusions The calcium phosphate powder in styrene–butadiene emulsion met basic requirements for a root canal filling material with promising properties.
