    Contemporary predoctoral paediatric behaviour guidance education in the United States and Canada
    (Wiley, 2022) Weishuhn, David; Scully, Allison; Amini, Homa; Salzmann, Larry; Boynton, James R.; Pediatric Dentistry, School of Dentistry
    Purpose: To determine the contemporary educational experiences of predoctoral dental students in the United States and Canada regarding behaviour guidance (BG) of the child patient and assess trends from a previous study in 2004. Methods: Data were collected from 32 predoctoral paediatric dentistry programme directors in the United States and Canada via a web-based survey. Results: The didactic curriculum hours devoted to the teaching of BG techniques in 2019 are similar to 2004. A majority (60.7%) of programmes do not have a formal assessment of competency with BG techniques. Lectures (n = 28), clinical experience (n = 28) and observation (n = 26) were the most common techniques implemented to teach BG techniques, and tell-show-do (100%), non-verbal communication (82.1%), positive reinforcement (89.3%) and distraction (82.1%) were the techniques that more than 75% of dental students most commonly have hands-on experience with during their dental education. In 2019, students tended to have more hands-on experience with nitrous oxide/oxygen inhalation and less hands-on experience with aversive techniques and sedation. Conclusions: The majority of dental schools do not have a formal competency in BG of the child patient. Compared with 2004, nitrous oxide/oxygen is used more by dental students and there is less predoctoral education in aversive BG techniques.

    Silver Diamine Fluoride and Progression of Incipient Approximal Caries in Permanent Teeth: A Retrospective Study
    (American Academy of Pediatric Dentistry, 2021) Polacek, Jenna; Malhi, Nimrat; Yang, Yu-Ju; Scully, Allison C.; Soki, Fabiana N.; Boynton, James R.; Pediatric Dentistry, School of Dentistry
    Purpose: The purpose of this study was to evaluate the progression of incipient approximal caries lesions in permanent teeth of children and adolescents with and without silver diamine fluoride (SDF) application. Methods: A retrospective analysis of dental records and radiographs was performed. Baseline and follow-up bitewing radiographs were evaluated and scored using International Caries Classification and Management System (ICCMS) criteria to assess lesion progression. Results: A total of 131 lesions from 68 subjects (mean age equals 9.6 years) were evaluated radiographically and followed for up to 41 months (mean time equals 13.61±6.8 months); 23.6 percent of lesions in the SDF group progressed compared to 38.1 percent in the control group (P<0.001). On average, lesions in the control group increased more per month compared to the study group (P<0.001). The odds of lesion progression in the control group were 2.76 times the odds of progression in the study group. There was a statistically significant difference in lesion progression based on application method; lesions where SDF was applied with Superfloss progressed more per month, on average, versus microbrush application. Conclusions: Silver diamine fluoride may be an effective therapy to slow caries progression of incipient approximal lesions in permanent teeth in high caries-risk populations. Future studies are needed to detect differences in application methods.
