Zinc oxide eugenol and Endoflas pulpectomy in primary molars: 24-month clinical and radiographic evaluation.

CONTEXT: Despite modern advancement in material and technical aspect, management of infected primary molars is of prime concern in pediatric endodontics. An effective root canal material plays the major role in achieving the fluid impervious seal by defending against variant microflora and maintaining the tooth in function for longer duration. AIMS: This study aims to evaluate and compare the success of endoflas as root canal filling material in infected primary molars with zinc oxide eugenol (ZOE). MATERIALS AND METHODS: Primary molars with necrotic pulp in healthy, cooperative children were selected. Ethical clearance and informed consent was obtained. Standardized pulpectomy procedure was done and root canals were filled with either ZOE or endoflas. Further follow-up with clinical and radiographic evaluation was carried at 0, 3, 6, 12, and 24 months. The findings obtained were statistically analyzed using Chi-square test. RESULTS: Endoflas showed acceptable results as root canal filling material in primary molars even at 2-year follow-up, though overfilling of root canals led to low success rate compared to teeth with combined optimal and under fillings. There was no significant difference between the two materials (P > 0.05). CONCLUSIONS: Endoflas could be a potential alternative to ZOE for preserving infected primary molars.

A comparative assessment of different techniques for obturation with endoflas in primary molars: An In vivo Study.

PURPOSE: The rationale of this in vivo study was to evaluate and compare different obturation techniques for the intracanal conveyance of Endoflas in the primary molars using conventional radiography. MATERIALS AND METHODS: Thirty-eight children (4-9 years old) with total of 45 pulpally infected primary mandibular molars indicated for pulpectomy were categorized into three groups (i) endodontic pluggers, (ii) lentulospirals, and (iii) NaviTips, respectively, for obturation with Endoflas. The level of obturation and the presence of voids were evaluated radiographically, and the obtained data were statistically analyzed using Chi-square test. RESULTS: The results showed no significant difference between the three techniques to deliver Endoflas. Motor-driven lentulospirals showed better results (64.4% optimal fillings) compared to the pluggers (62.2%), but NaviTips showed poor results (48.9%) for the level of obturation (P > 0.05). Voids were observed in all the techniques used. Pluggers and lentulospirals showed similar results with greater void-free canals, whereas NaviTip system showed more voids which was statistically not significant (P > 0.05). CONCLUSION: Motor-driven lentulospiral and pluggers were almost equally efficient to fill Endoflas to an optimal level, devoid of voids, and both were considered better compared to NaviTip system.
