Comparative evaluation of biodentine, 2% chlorhexidine with RMGIC and calcium hydroxide as indirect pulp capping materials in primary molars: An in vivo study.

BACKGROUND: Indirect pulp therapy (IPT) is conventional treatment of deep dentinal carious lesions without risk of pulp exposure. Development of new biomaterials with biocompatibility and seal has changed the attitudes toward IPT. AIM/OBJECTIVES: This study was conducted to evaluate and compare the clinical and radiographic success of biodentine, 2% chlorhexidine gluconate with resin-modified glass ionomer cement (RMGIC), and calcium hydroxide as indirect pulp-capping materials in primary molars over an observation period of 12 months. MATERIALS AND METHODS: A total of 54 primary molars within the age group of 3-9 years, which were indicated for IPT were randomized into three groups of 18 samples each; Group I: biodentine, Group II: 2% chlorhexidine gluconate followed by RMGIC, Group III: calcium hydroxide (Dycal). These cases were followed up for evaluation clinically and radiographically at 3, 6, and 12 months. The recorded data were subjected to statistical analysis using Chi-square test. RESULTS: After 12 months, the clinical and radiographic success of biodentine group was 100% (18/18), with 2% chlorhexidine gluconate disinfecting solution followed by RMGIC was 94.4% (17/18) and calcium hydroxide (Dycal) was 94.4% (17/18), failures included one at 3 months with RMGIC and another at 12 months with calcium hydroxide group; but there was no statistically significant difference observed between them with P = 0.361 at 3 months and P = 0.371 at 12 months interval. CONCLUSION: Biodentine can be effectively used as indirect pulp-capping medicament in primary teeth which has similar clinical and radiographic success as 2% chlorhexidine gluconate in conjunction with RMGIC and calcium hydroxide.

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.
