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.

Introduction: The quick spread of SARS-CoV-2 led to the development of vaccines that are capable of reducing infection and the number of more severe COVID-19 cases. Aim: To assess COVID-19 prevalence among health care workers (HCWs) after vaccination against SARS-CoV-2. Methods: Cross-sectional study on the prevalence of COVID-19 diagnosis among 7.523 HCWs vaccinated against SARS-CoV-2 with Coronavac and ChAdOx1 nCoV-19 in a university hospital, in southern Brazil, between January 18, 2021 and March 18, 2021.The variables evaluated were: sex, age, work area, role, source of infection, previous diagnosis of COVID-19, date of vaccine administration, type of vaccine, and need for hospitalization. The statistical analysis used Poisson regression and Fisher's Exact Test with the SPSS software version 25 and level of significance set at 5%. Results: 813 vaccinated HCWs showed symptoms suggestive of COVID-19, and 35.4% (288) who underwent RT-PCR for SARS-CoV-2 had a detectable result. There was a reduction of 62% in new cases of COVID-19 among HCWs in the institution after seven weeks of the start of the vaccine rollout. Conclusion: Our data suggest that the vaccines used by the institution reduced the number of COVID-19 cases among health care workers, showing the effectiveness of the vaccines.

In cases of trauma, dental fragments occasionally penetrate into the soft-tissues and may cause severe complications, if neglected. Clinical and radiographic examinations can provide a diagnosis and help in the surgical removal of any dental fragment embedded in soft-tissue. This case report concerns an 8-year-old boy who was diagnosed with a fragment of a fractured permanent central incisor crown located in the lower lip. The patient was seen initially at a general hospital, where the dental fragment went unnoticed. After 2 days, the patient was seen at the pediatric dentistry clinic, where a fragment embedded in the lower lip, causing a large swelling, was diagnosed. The fragment was removed surgically and bonded to the fractured tooth. A mouth guard was prescribed for sports. The importance of soft-tissue exploration even post-trauma was highlighted in this paper.
