Obturating Materials in Primary Teeth-A Review

Anagha Chonat, T Rajamani and Rena Ephraim

Treatment of pulpally inflamed primary and permanent teeth in children presents a unique challenge to the dental clinician. Although the number of children experiencing caries and pulpal pathologies has considerably lowered due to dental health education, pulpal pathologies still persists. It eventually leads to development of malocclusion. Pulp therapy in deciduous teeth differs from that of the permanent teeth, so the medicaments used and the obturation technique. Adequate cleansing by mechanical instrumentation and irrigation of the canals is difficult in deciduous teeth due to its complex and variable root canal morphology. Hence the success of the treatment in such cases would depend upon complete obturation of the canal space Various materials had developed for obturation of primary teeth. Zinc Oxide Eugenol cement (ZOE) has long been used as a root canal filling material for deciduous teeth, but cannot be considered the ideal root canal filling material because as it presents limited antimicrobial action and slow rate of resorption. Concerns about these shortcomings of ZOE and the need for materials that resorb at the same rate as that of the deciduous teeth led to the search for alternative root canal filling material for deciduous teeth. The present article reviews the materials used in pulpectomy and provides an overview of the newer material trials of obturation in pediatric dentistry.
