The aim of this retrospective anonymized evaluation was to investigate possible effects of SIP interruption on oral health in socially vulnerable 7- and 8-year-olds. Methods: The caries increment in 7- and 8-year-olds for the test group (N = 180) between last dental check-up before the interruption of SIP (02\/2019\u201302\/2020) and the first check-up after restart (01\/2022\u201307\/2022) were calculated from dental public health service data. The test group was compared to a control group of children (N = 215; same age and schools, with SIP, data collected between the school year 2017\/18 and 2019\/20). One dentist conducted the dental examinations. The University of Marburg ethics committee approved the study. The Mann\u2013Whitney U test and Pearson\u2019s chi-square test were used for statistical analysis. Results: There was no significant difference in the caries increment in the first dentition between the test and the control group for both age groups. In the different groups, a maximum of 61% of the children with caries experience were completely treated. There was no significant difference between the test and control groups in either the percentage of sealed first permanent molars or the degree of restoration. Conclusions: The interruption of SIP had no negative impact on caries increment. It is possible that the children examined went through the pandemic without a significant increase in tooth decay because the children were well-trained in tooth brushing since kindergarten.<\/jats:p>","DOI":"10.3390\/children12030315","type":"journal-article","created":{"date-parts":[[2025,2,28]],"date-time":"2025-02-28T10:12:33Z","timestamp":1740737553000},"page":"315","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Impact of Interrupting Oral Prevention on Dental Health of 7- to 8-Year-Old Children Due to COVID-19"],"prefix":"10.3390","volume":"12","author":[{"given":"Julia","family":"Winter","sequence":"first","affiliation":[{"name":"Department of Operative Dentistry, Endodontics, and Pediatric Dentistry, Medical Center for Dentistry, University Medical Center Giessen and Marburg, Campus Marburg, Georg Voigt Str. 3, 35039 Marburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thea","family":"Hartmann","sequence":"additional","affiliation":[{"name":"Department of Operative Dentistry, Endodontics, and Pediatric Dentistry, Medical Center for Dentistry, University Medical Center Giessen and Marburg, Campus Marburg, Georg Voigt Str. 3, 35039 Marburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Constanze","family":"Schul","sequence":"additional","affiliation":[{"name":"Public Health Department in the District of Marburg Biedenkopf, Schwanallee 23, 35037 Marburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Esther","family":"H\u00f6rschgen","sequence":"additional","affiliation":[{"name":"Public Health Department in the District of Marburg Biedenkopf, Schwanallee 23, 35037 Marburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Miriam","family":"Th\u00f6ne-M\u00fchling","sequence":"additional","affiliation":[{"name":"Public Health Department in the District of Marburg Biedenkopf, Schwanallee 23, 35037 Marburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Birgit","family":"Wollenberg","sequence":"additional","affiliation":[{"name":"Public Health Department in the District of Marburg Biedenkopf, Schwanallee 23, 35037 Marburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stefanie","family":"Amend","sequence":"additional","affiliation":[{"name":"Department of Pediatric Dentistry, Medical Center for Dentistry, University Medical Center Giessen and Marburg, Campus Giessen, Justus-Liebig-University Giessen, Schlangenzahl 14, 35392 Giessen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5112-4463","authenticated-orcid":false,"given":"Roland","family":"Frankenberger","sequence":"additional","affiliation":[{"name":"Department of Operative Dentistry, Endodontics, and Pediatric Dentistry, Medical Center for Dentistry, University Medical Center Giessen and Marburg, Campus Marburg, Georg Voigt Str. 3, 35039 Marburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,2,28]]},"reference":[{"key":"ref_1","first-page":"761","article-title":"Der kariostatische Effekt von Duraphat nach 6 Jahren in Abh\u00e4ngigkeit vom Kariesrisiko","volume":"47","author":"Klimek","year":"1992","journal-title":"Dtsch.
