Purpose/objectives: To survey potential applicants applying to advanced education in pediatric dental programs and evaluate their preparedness upon graduating from an accredited dental school. Methods: Attendees of a virtual externship of a University program were recruited to participate in a web‐based survey. The survey collected demographic data, current levels of confidence with various pediatric clinical procedures, predicted confidence with those procedures, and number of procedures completed. Chi‐Square and analysis of variance statistics were performed on resulting data to determine statistical significance. Results: Fifty‐three participants completed the survey in its entirety (n = 53). Most respondents reported adequate didactic training, mean score of 3.6 (range 0–5) and a moderate to high impact of coronavirus disease 2019 on their overall training with a mean score of 4.9 (range 0–10). Current dental students reported that they are "not confident at all" (<2.0) for 15/24 (63%) of the procedures. Graduates reported "somewhat confident" (<3.0) for 13/24 (54%) of the categories. Both students and graduates report the lowest levels of confidence for managing dental trauma, invasive treatment of young patients (<4 years of age), and patients with special healthcare needs. Dental students self‐reported the expectation to feel more confident throughout their matriculation; however, their clinical experience was still reported to be limited. Students did not report reaching the level of "confident" for 75% of the procedures. Conclusion: Dental students and recent dental graduates alike perceive themselves to be under prepared for practice and do not feel confident in performing pediatric dental procedures. This study can provide dental schools, program directors, recent graduates, and dental students with an understanding of areas where they are under prepared and could offer areas where curricula and clinical experiences could be updated or modified.

The transport and fate of pesticides applied to nursery crops are not well documented. The major objective of this study was to examine simazine (2-chloro-4,6-bis(ethylamino)-s-triazine), 2,4-D ([2,4-dichlorophenoxy] acetic acid), and [...]

Purpose: The purpose of this study was to investigate the microleakage of atraumatic glass ionomer restorations with and without silver diammine fluoride (SDF) application. Restorations with SDF are termed silver-modified atraumatic restorations (SMART). Methods: Sixty carious extracted permanent teeth were randomly allocated to two SMART groups and two control groups (n equals 15 per group) for a total of four groups. After selective caries removal, test specimens were treated with 38 percent SDF and polyacrylic acid conditioner was applied and rinsed; teeth were restored with Fuji IX GP® glass ionomer (n equals 15) or with SMART Advantage™ glass ionomer (SAGI; n equals 15). For control groups, specimens were restored with their respective GI material after selective caries removal, both without SDF. Restored teeth were placed in Dulbecco's Phosphate-Buffered Saline solution at 37 degrees Celsius for 24 hours. Teeth were thermocycled between five and 55 degrees Celsius for 1,000 cycles, stained with two percent basic fuchsin, sectioned, and visually inspected for microleakage utilizing stereomicroscopy on a four-point scale. Data were statistically analyzed using Kruskal-Wallis one-way analysis of variance on ranks using Dunn's method (P<0.05). Results: Microleakage between the two SMART restoration groups was insignificant. SAGI alone demonstrated significantly more microleakage than all other groups. There was no statistical significance between the Fuji IX GP® control group and the two SMART restoration groups. Conclusions: This in vitro study indicated that silver diammine fluoride placed before glass ionomer restoration does not increase microleakage. Polyacrylic acid may be used after SDF placement without increasing microleakage. [ABSTRACT FROM AUTHOR]

Multiple linear regression analysis determines the increments in reversed- phase liquid chromatographic (RPLC) retention of 75 4,4'-disubstituted benzanilides and benzamides as a function of variations in the stationary and mobile phases. The study, which illustrates the sensitivity of RPLC to slight changes in molecular environments, shows that functional group retention depends on both the stationary and mobile phases. A statistical intracolumn bilogarithmic analysis, however, yields standardized functional group substituent constants that are phase-independent.
