The aim of this systematic review was to determine whether there is a root canal filling for deciduous teeth equally or more effective than zinc oxide-eugenol cement (ZOE). Six clinical trials selected for inclusion were independently reviewed by two researchers. Only two showed statistically significant different success rates between the test and the control groups. One found that an iodoform paste with calcium hydroxide (IP + Ca) performed better than ZOE, and the other found that ZOE performed similarly to IP + Ca. The other four studies compared ZOE with an iodoform paste (IP), a calcium hydroxide cement (Ca(OH)2), or IP + Ca. In these trials, the success rates in the ZOE groups were slightly lower than in the other groups. There seems to be no convincing evidence to support the superiority of any material over ZOE, and both ZOE and IP + Ca appear to be suitable as root canal fillings for deciduous teeth.

Background Silver diamine fluoride (SDF) causes dental black staining after its application. Aim Evaluate the aesthetic perception, acceptability, and/or satisfaction of patients, parents, and professionals to the treatment of caries lesions with SDF through a scoping review. Design A search was performed in seven databases and two key journals with no language or date restrictions. Studies that evaluated the aesthetic perception, satisfaction, and/or acceptability of patients, parents, and professionals to the treatment of carious lesions with SDF were considered eligible. Results From a total of 1177 articles, 10 studies were full text assessed for eligibility, with nine included in this scoping review. In general, the studies varied by population, study design, and methodologic evaluation. The type of tooth (anterior or posterior), family income, parental schooling, ethnicity, and need for advanced behaviour control methods were factors that influenced the results. The acceptability level increased as the child required more advanced methods of behaviour guidance. In general, the pigmentation caused by SDF did not interfere with the parents’ acceptability of the treatment; however, professionals believe that this could have influence. Regarding satisfaction, pigmentation did not influence parental satisfaction. Conclusion Parents were satisfied with and found SDF acceptable, whereas professionals did not.

Objective: Current acceptability, barriers to use, and clinical/teaching practices of Silver Diamine Fluoride (SDF) among Brazilian dentists were investigated. Material and Methods: A Google forms questionnaire was sent to dentists (n=10,500) to collect information about the use of SDF and the dentists' workplace, experience, specialty, and city of practice. A logistic regression model was performed. Results: From 409 respondents, 13.2% used SDF. Working at universities increased the use of SDF by 2.29 times (p=0.018) compared to private offices. Each training year, the chance of SDF usage increased by 3% (p=0.008). Pediatric dentists are more likely to use SDF (OR=6.76, p<0.001). There is no association between SDF usage and the city of practice. The majority (75.9%) indicated SDF for noncompliant patients. Dentists (75.9%) reported the exclusive use in deciduous teeth, while 24.1% also use in permanent teeth. The main barrier for non-users was a lack of knowledge (58.3%), while for users, tooth staining (90.7%) and parental acceptance (64.8%) were the complaints. Conclusion: The Silver Diamine Fluoride is not a common product used by the dentists from RJ. Its clinical applicability should be further disseminated; thus, lack of scientific knowledge would cease to be a problem in the use of SDF to arrest caries lesions.
