Materials and methods: Thirty patients of age group 15-50 years with single-rooted teeth were selected. After access opening and working length (WL) determination, the pretreatment sample (S1) was obtained using a sterile paper point dipped in transport media. Biomechanical preparation (BMP) was done with master apical file size #40 and step-back up to size #60. The patient was randomly divided into three groups and irrigation was done. Group I-2% chlorhexidine gluconate (CHX), group II-neem juice extract, and group III-tulsi juice extract. Postinstrumentation sample (S2) was taken in the same manner. Canals were dried and three solutions were dispensed as intracanal medicaments. A double seal of Cavit was placed. After 7 days, post-medicament sample (S3) was collected in the same manner as S1. Microbiological samples (S1, S2, S3) were incubated and then plated on brain heart infusion agar and the colonies were counted. Collected data were statistically analyzed using repeated measures of analysis of variance (ANOVA). Results: The results of this study demonstrated that a statistically significant reduction was seen among all the groups during the intragroup comparison. The reduction in S3 from S1 was found to be significantly higher than that found in S2 from S1, which was further significantly higher than that found in S3 from S2. In intergroup comparison, the difference in colony counts reached the level of statistical significance in S2 from S1 and in S3 from S1 in all the three experimental solutions. Among these stages, a significant reduction was seen in group I and group II, group I and group III. Conclusion: Therefore, within the limitations of this study, it can be concluded that herbal products have shown significant antimicrobial activity in primary endodontic infections when compared to 2% CHX. Hence, they can be recommended as endodontic irrigants and medicaments. Clinical significance: Herbal products can be recommended as endodontic irrigants and medicaments.

A major etiological factor for treatment failure is the inability to detect extra roots/canals. Anatomical variations can be present in any tooth and it is important for the clinician to explore any unusual anatomical variations during every step. The incidence of three distinct roots in a maxillary first premolar ranges from 0.4 to 9.2%. The successful endodontic treatment of a maxillary premolar with three roots is described in this case report.

Methods: Active controlled and parallel design trial was registered with Clinical Trials Registry India under reference no. CTRI/2018/08/015478. Forty-eight qualified patients were randomly divided into three groups (n = 16 each) using the lottery method, Group-I: CEI, Group-II: PAD, Group-III: CEI and PAD. Access opening and working length were determined, and preinstrumentation sample (S1) was taken by inserting sterile paper point into the canal. Postinstrumentation sample (S2) was collected following biomechanical preparation and irrigation with respective interventions. Microbiological samples (S1, S2) were plated on brain heart infusion agar. Colony-forming units were counted using the classic bacterial counting method, and percentage bacterial reduction was determined. Statistical Analysis: Inter- and intra-group comparison was made using repeated measures of ANOVA. Post hoc Tukey analysis was done for pairwise comparison with P < 0.05. Results: In the intragroup comparison, statistically significant reduction was seen at S2 among all experimental groups. However, in intergroup comparison, mean bacterial reduction in Group III was significantly lower than the other groups. This difference was statistically significantly better between Group I and Group III; Group II, and Group III. However, no statistically significant difference was seen between Group I and Group II. Within the limitations of this study, it can be concluded that a combination of CEI and PAD showed significantly better antimicrobial activity against primary endodontic infections and can be recommended as an adjunct to facilitate maximum root canal disinfection.

Materials and methods: Ninety patients with ninety single-rooted teeth were selected. After complete disinfection, access opening was made and sample S1 was collected with paper point after injecting 5 mL of normal saline. After working length determination and biomechanical preparation till #40 K-file, sample S2 was collected in the same manner as S1. The canals were dried and the three intracanal medicaments were mixed with propylene glycol. The patients were randomly divided into three groups (n = 30) and the medicaments (group I-CH, group II-TAP, and group III-DAP) were placed. After 7 days, following medicament removal, sample S3 was collected. Microbiological samples (S1, S2, and S3) were preincubated for 30 minutes and then plated on brain heart infusion agar and colonies were counted after 24 hours using the classic bacterial counting method. Results: There was significant reduction of bacterial count from stages S1 to S2 and S2 to S3 in all the three experimental groups. The maximum reduction of bacterial count (CFU/mL × 10 5) at S1, S2, and S3 stages and reduction in mean was seen in group III. However, there were no statistically significant difference between group II (TAP) and group III (DAP). Conclusion: The TAP and DAP have similar antimicrobial efficacy though better than CH.

There is a necessity to induce or create an apical barrier against which the obturating material can be compacted. The present article reports the effective closure of root apex in a pulpless permanent upper incisor tooth with wide-open apex utilizing Biodentine in blend with platelet-rich fibrin in the form of a matrix showing excellent healing potential at a 12-month follow-up.

Fifty freshly extracted intact human permanent maxillary central incisors were collected, stored and disinfected. The root canals were prepared to a master apical size of number 50 using step back technique. Depending upon the intracanal medicament used, the teeth were divided randomly into five groups of 10 teeth each including one control group and four experimental groups. Group A: No intracanal medicament. Group B: Calcium hydroxide powder mixed with distilled water. Group C: Calcium hydroxide gutta percha points (calcium hydroxide points). Group D: 1% chlorhexidine gel (hexigel). Group E: Chlorhexidine gutta percha points (Roeko Activ Points). The medication was left in canals for 14 days. Following removal of the intracanal medicament, all the groups were obturated with lateral compaction technique. The apical leakage was then evaluated using dye extraction method with the help of a spectrophotometer. RESULTS were statistically analyzed using Kruskal-Wallis and Mann-Whitney U-test, which showed statistically significant difference among the five groups tested. It can be concluded from this study that the control group showed least amount of leakage, whereas the 1% chlorhexidine gel group showed maximum amount of leakage. Apical leakage was observed with all the experimental groups with little variations in between them. Under the parameters of this study, it can be concluded that use of intracanal medicaments during endodontic treatment has a definite impact on the apical seal of the root canal system.

Materials And Methods– 30 single rooted permanent teeth diagnosed clinically and radiographically with necrotic/infected pulp were included. After complete disinfection, access opening was done and working length was determined. The rst microbiological pre-treatment sample (S1) was collected by paper points. After completion of instrumentation, a post-instrumentation sample (S2) was taken and the teeth were divided into two groups: Group 1: calcium hydroxide, Group 2: Silver nanoparticles. The intracanal medicaments were left in place for 7 days. Post 1 week, S3 was taken. Samples collected were cultured on BHI agar and colony forming units were counted after 24 hours. Results- Intergroup comparison was done using Mann Whitney U test & intragroup comparison was done using Friedman test & Wilco...
