Context:A major goal in pediatric dentistry is preservation of the integrity of primary teeth and their supporting tissues until physiological process of exfoliation takes place. Pulpectomy serves such a purpose using various materials and techniques to fill the canals of primary teeth. Aims: The aim of this in vivo study was to determine the efficacy of modified disposable syringe technique in root canals of primary molars using digital radiography when obturated with endoflas.Settings and Design:A clinical study was undertaken for a period of 6 months.Subjects and Methods:A total of 60 primary maxillary and mandibular molars were selected in the age group of 4–8 years and randomly divided into two groups. The teeth were obturated with handheld lentulospiral and a modified disposable syringe techniques. Postoperative radiographic evaluation was done for quality of fill and voids using digital radiography. Statistical Analysis Used: Results were assessed using Chi-square test and Mann–Whitney U-test. Results: No statistically significant difference between quality of obturation using hand-held lentulospiral and modified disposable syringe (P < 0.05) was observed. Optimal obturation was achieved in both techniques; however, voids in obturation were not significant.Conclusions:Both the hand-held lentulospiral and modified disposable syringe technique are effective in the obturation of primary molar root canals in terms of quality of fill.

Management protocol for avulsed teeth includes the maintenance of viable periodontal ligament (PDL) cells for good prognosis and long-term survival of these teeth. The desirable treatment is immediate replacement and replantation of the avulsed tooth but it cannot always be accomplished for a number of reasons. Thus, the tooth should be transported in a suitable storage medium to maintain the cell viability. Considering the critical role of these media, an informed choice of a suitable medium is essential for a favourable outcome. This review paper focuses on the various storage media available and highlights their specific features or drawbacks.
