RESUMEN
Context: Antimicrobial intracanal medicaments play a vital role in successful outcome of any endodontic procedure. One such plant extract Cuminium cyminium, as intracanal medicaments needs to be researched. Aims: The purpose of this study was in vitro assessment of the antibacterial activity of ethanol extract of C. Cyminium in comparison to Calcium hydroxide (Ca[OH]2) as intracanal medicament against the pathogens of endodontic infection, at an interval 1 h, 24 h, 48 h, and 72 h. Settings and Design: The study was conducted in the central research laboratory of our institute. Freshly prepared C. cyminium extract was procured from AYUSH approved laboratory and direct contact test (DCT) was utilized, which is based on turbidometric determination of microbial growth in a 96-well microplate, carrying 6 times for each bacteria. Methodology: Three groups were assigned for each material in a 96 microwell plate for DCT. Bacterial growth kinetics was monitored at intervals of 1 h, 24 h, 48 h, and 72 h using spectrophotometer at 595 nm. The optical density of T2 (Test group), P2 (Positive control), and N2 (Negative control) was considered. Statistical Analysis Used: After compiling the data, based on the normality of data, further statistical analysis was conducted using Kolmogorov-Smirnov test, Paired t-test, and pairwise comparisons by Turkey's multiple post hoc procedures. The level of statistical significance was set at P = 0.05. Results: The comparison of mean optical density values of C. cyminium in comparison with Ca(OH)2 against the microorganisms of endodontic origin showed a statically significant decrease in bacterial viability at the end of 24 h, 48 h, and 72 h. Conclusion: Based on the results of the study, it can be concluded that C. cyminium has significant antibacterial action against endodontic origin, at interval of 24 h, 48 h, and 72 h.

BACKGROUND: Stainless steel crowns (SSCs) are unique coronal restorative materials used commonly in the management of primary teeth with extensive caries. AIM: The aim of this study was to perform a systematic review to evaluate the retentive strength of luting cements for SSCs. MATERIALS AND METHODS: Two reviewers performed a database search of the studies published from 2004 till date. The inclusion criteria were papers published in the English language andin vitro studies on retentive strength of SSC on primary molars. All potentially relevant studies were identified by the title and the abstract. After the full-text analysis, the selected studies were included in the systematic review. RESULTS: Sixteen nonduplicated studies were found. However, after reviewing the articles, only seven were included. Risk bias was assessed. Out of seven studies included in the systematic review, five studies presented medium risk of bias and two studies showed high risk of bias. CONCLUSION: Within the limitations of this study, thein vitro literature seems to suggest that the use of self-adhesive resin cements shows higher retentive strength, followed by resin-modified glass-ionomer cement (RM-GIC) and conventional GIC. However, RM-GIC can be a preferred luting agent due to its clinical advantages over resin cements. Thus, it can be concluded that choice of cement will depend on individual patient needs and clinical situation.

AIM: To determine the prevalence of child behavior management problems (BMP) and to analyze the influence and predictive power of nondental and dental background variables on BMP. STUDY DESIGN: Prospective analytical study. MATERIALS AND METHODS: The study group included 165 children aged 7-11 years who received comprehensive dental treatment, after obtaining written informed consent. Parents/guardians were interviewed using standardized questionnaire to obtain background information. Each child's treatment was carried out and was recorded with a fixed digital video (DV) recorder. The treatments were classified into three levels of invasiveness: Noninvasive (NI), moderately invasive (MI), and highly invasive (HI). The entire DV record of each treatment was observed, and child's dental behavior was rated independently by two precalibrated examiners using modified Venham's behavior rating scale. Then, the background factors obtained through the questionnaire data were analyzed for its association with child's dental behavior. RESULTS: Statistical tests used were Chi-square test and multiple logistic regression analysis to determine the relationship of multiple variables with dental behavior. Comparison of child's behavior during different visits was done by Wilcoxan matched pairs test. The prevalence of BMP in children aged 7-11 years in the study sample was 0%, 4.2%, and 15.76% for NI, MI, and HI procedures, respectively. Three variables were significant predictors of behavior; order of birth that is, first born, history of hospitalization, and unpleasant past dental experience (P < 0.05). CONCLUSIONS: Direct conditioning pathway is the major factor in determining child's behavior. Dental experiences, duration of treatment, and complexity of treatment have greater impact on how the child behaves in a dental setup.

Post orthodontic treatment, retention is one of the most important step for prevention of relapse. Over the years many direct and indirect techniques for placing a bonded lingual retainer have been practiced clinically. Present clinical practice demands a much convenient and effortless technique for bonding a lingual retainer. This article describes a simplified technique of bonding a lingual retainer.
