To compare the timing of instrumentation and cleaning efficacy between manual K files and NiTi rotary files in extracted primary molars. Study design: in-vitro study was conducted in 90 root canals of extracted primary molars which were subdivided in three groups viz. Control (No instrumentation), Manual (K files), Rotary (ProFiles) with 30 canals in each group. Mesiobuccal (MB) and Mesiolingual (ML) canals of mandibular molars, and MB and Distobuccal (DB) canals of maxillary molars were included in the test group whereas Distal canals in mandibular molars and Palatal canals in maxillary molars were included in the control group. Method: Teeth were mounted and canals were injected with India ink to stain the canal walls. Canal preparation was done as per the group. After instrumentation, teeth were demounted, decalcified and cleared to make them transparent for scoring according to the extent of removal of India ink. Timing of instrumentation and cleaning efficacy of canals in coronal, middle and apical thirds were assessed in each sample. Results: Mean timing of instrumentation in rotary group was 3.54 ± 1.14 min and 4.32 ± 1.04 min in manual group. Mean cleaning efficacy scores in manual and rotary groups were 2.03 and 1.66 in coronal third, 1.08 and 1.18 in middle third and 0.67 and 1.08 in apical third respectively. Inter-group comparisons showed no statistically significant difference in cleaning efficacy among test groups in all thirds of root canals. Conclusion: NiTi rotary technique has comparable cleaning efficacy, with significantly less timing of instrumentation compared to manual K-files.
Aim
The study was designed to evaluate and compare the success of Biodentine and mineral trioxide aggregate (MTA) in comparison to formocresol as pulpotomy medicaments over 9 months of the follow-up period.
Materials and methods
The sample of 60 deciduous molars of patients aged 4–7 years were incorporated in the study. The molars were randomly allocated to the experimental and control groups. Following coronal pulp removal and achieving hemostasis, the radicular pulp was covered with either Biodentine or MTA (experimental groups). In the control group, a cotton pellet soaked with diluted formocresol (one-fifth dilution of Buckley's formocresol) was placed over the radicular pulp for 1 minute. All pulpotomized molars were later restored with stainless steel crowns (SSCs).
Results
The achieved clinical success over 9 months of the follow-up period was 100, 95, and 70% with Biodentine, MTA, and formocresol, respectively. The achieved radiographic success over 9 months of the follow-up period was 95, 60, and 25% with Biodentine, MTA, and formocresol, respectively.
Conclusion
Favorable biological, physical, mechanical, and good manipulation properties of Biodentine show that this material can be used efficiently as a pulpotomy medicament in the clinical practice.

AimParental presence often provides unique challenge in dental operatory and is directly related to the quality dental treatment. The present study was done to investigate parent’s ability to assess dental anxiety of their 6- to 10-year-old child and to determine how parent’s and children’s fear assessments correlate with each other.Materials and methodsPrior to dental treatment, 94 child-parent combinations were included to complete Children’s Fear Survey Schedule—Dental Subscale (CFSS-DS) questionnaire, and Frankl score was assigned to children during treatment by operator.ResultsMean dental anxiety score reported by the children was 27.74, whereas by their parents was 39.64. There was a poor consistency of parents to predict their child dental fear (p < 0.05). Parents reported higher dental fear for their children.ConclusionParents assessment of their child’s fear may vary in accordance to factors, including their own dental fear. Such input may prevent dentists from establishing an accurate association with the child’s patient.How to cite this article: Malhotra R, Gandhi K, Kumar D, Ahuja S, Kapoor R, Sahni A.
