Clinical Assessment of Various Obturating Techniques for Primary Teeth: A Comparative Study

Abstract

Introduction: Lifelong preservation of tooth in a healthy state is the ultimate goal of dentistry. Premature loss of primary teeth is common due to caries, dental trauma or other causes. As the primary teeth are the best space maintainers, teeth with infected pulps should be retained until exfoliation, whenever possible. Aim: The purpose of this in vivo study was to evaluate and compare the efficacy of different obturating methods used in primary teeth. Materials and Methods: Forty one patients aged four to nine years with a total of 60 teeth were selected. Out of the 60 teeth, 32 were primary mandibular first molars and 28 were primary mandibular second molars, the sample was randomly divided into three groups. Disposable syringe, lentulo spiral and past inject were used for obturation. Postoperative evaluation was done for; quality of canal obturation, presence of voids using postoperative radiographs following obturation of teeth. The data were analysed to assess the success rate of the three methods used for obturation using Chi-square test. Results: Among the three groups of the study, past inject exhibited the maximum number of optimally filled canals. Maximum number of underfilled canals was found with lentulospiral, and the maximum number of overfilled canals was seen with disposable syringe. Least number of voids was observed in canals filled with the past inject technique and disposable syringe. Conclusion: The results suggest that the most successful technique for obturation of primary teeth was past inject.
