Comparative Analysis of Biodentine, Calcium Hydroxide, and 2% Chlorhexidine with Resin-modified Glass Ionomer Cement as Indirect Pulp Capping Materials in Young Permanent Molars.

AIM AND OBJECTIVE: This study was carried out to compare the effectiveness of biodentine, calcium hydroxide, and 2% chlorhexidine gluconate used along with resin-modified glass ionomer cement (RMGIC) as indirect pulp capping (IPC) materials in young permanent molars. MATERIALS AND METHODS: In this study, 54 patients were selected. Among these patients, 72 young permanent molars were selected randomly in which IPC was required. These teeth were randomly categorized into three different groups and each group consisted of 24 teeth. The first group was group A consisting of teeth treated with biodentine, the second group was group B consisting of teeth treated with 2% chlorhexidine gluconate being followed by RMGIC, while the third was group C consisting of teeth treated with calcium hydroxide. All cases were subjected to follow-up for clinical and radiographic evaluation at 4, 8, and 16 months. The data were recorded and analyzed statistically by utilizing the Chi-square test. RESULTS: After 16 months, 95.83% of cases in group A consisting of teeth treated with biodentine showed successful results both clinically and radiographically. While 87.5% of cases in group B consisting of teeth treated with 2% chlorhexidine gluconate being followed by RMGIC showed successful results. And finally, 91.66% of cases in group C consisting of teeth treated with calcium hydroxide showed successful results. CONCLUSION: Biodentine can be efficiently used as an IPC agent in young permanent molars although all three materials were effective in IPC with a nonsignificant difference statistically. This study highlights the success of IPC in young permanent molars and the choice of better IPC material can be biodentine. CLINICAL SIGNIFICANCE: Indirect pulp capping is one of the procedures in which preservation of carious affected dentin nearest to the pulp is carried out to protect the pulp. Several new IPC agents like biodentine have been introduced. Hence, it is necessary to evaluate their effectiveness. How to cite this article: Kaul S, Kumar A, Jasrotia A, et al.

Comparison of Five Different Irrigation Techniques on Smear Layer Removal in Apical Thirds of Root Canals of Mandibular First Premolar: A Scanning Electron Microscopic Study.

AIM: This study was conducted to compare smear layer removal by five different irrigation techniques-conventional needle irrigation (CI), manual dynamic activation (MDA), passive ultrasonic irrigation (PUI), sonic irrigation (SI), and negative apical pressure (NAP). MATERIALS AND METHODS: Fifty freshly extracted mandibular first premolars were cleaned and shaped by One Curve rotary files and 3% sodium hypochlorite and 17% ethylenediaminetetraacetic acid. The samples were divided into five equal groups (n = 10), according to the final irrigation activation technique: Group I, CI; Group II, MDA; Group III, PUI; Group IV, SI; and Group V, NAP. The samples were prepared and observed under a scanning electron microscope. The photomicrographs were recorded and evaluated with a scoring system. RESULTS: Group I and Group II had the highest scores, which showed a statistically significant difference between the other groups (P < 0.05). This was followed by PUI, NAP, and SI. CONCLUSION: Final irrigation activation with SI and NAP resulted in the better removal of smear layer when compared to that with other groups.
