Background/Objectives: In Marburg (Hesse, Germany), the selective intensive preventive program (SIP) with fluoride varnish applications had to be interrupted due COVID-19 pandemic. The aim of this retrospective anonymized evaluation was investigate possible effects SIP interruption on oral health in socially vulnerable 7- and 8-year-olds. Methods: caries increment 8-year-olds for test group (N = 180) between last dental check-up before (02/2019–02/2020) first after restart (01/2022–07/2022)...

A mesial 2 × 4 mm cervical groove created dentin simulate a deeper (dentin) caries excavation. This either left (G/groove), filled with composite (F/filling), or completely removed (D/dentin). Distal proximal...
Objectives: To investigate in vitro post-fatigue fracture behavior of endodontically treated molars having been differently restored. Methods: A total 120 extracted human were used. specimens 14 test groups and one control group (n = 8) root canal treated. After postendodontic sealing build-up (AdheSE Universal, SDR), additional MOD preparations cut. Postendodontic restorations were: Direct (Tetric EvoCeram BulkFill bonded with AdheSE Universal EverX Posterior/Essentia G-Premio Bond; as...
Background In areas with low caries prevalence, indices are needed for detection, which can also be used to identify initial lesions. Aim The aim of this study was assess the prevalence among 12‐year‐olds using ICDAS criteria and investigate influence independent variables on findings. Design conducted in two regions G ermany. R egion 1, children received regular school‐based prophylaxis, including fluoride varnish 2×/yr. 2, there no use schools. Information different factors influencing...
PURPOSE This in vitro study evaluated marginal integrity, 2-body wear, and fracture behavior of an array bonded nonbonded posterior restorative materials after thermomechanical loading (TML). MATERIALS AND METHODS Eighty-eight MOD cavities with one proximal box beneath the CEJ were prepared extracted human third molars according to a well-established protocol. Direct restorations made using following materials: amalgam (Dispersalloy), Ketac Molar Quick, Surefil One (with or without light...
SummaryThe influence of 5 tetrazolium compounds on growth various bacterial species is reported. Gram negative organisms are more resistant to the inhibitory effects these than gram positive organisms. The ditetrazolium salts lethal bacteria monotetrazolium salts.
It is still not fully understood what pretreatment best for achieving maximum tightness pit and fissure sealings (PFS).This study investigated microleakage of PFS placed after etching with phosphoric acid or the application self-etching primers/adhesives (SEPA).131 third molars were assigned to ten groups. In Hel-P, Helioseal® was applied etching. other groups, SEPA used (Dyr-AP: Adper™ Prompt™ L-Pop™, Dyract® Seal; Bea: BeautiSealant Primer Paste; Hel-Exp: Experimental primer, Helioseal®;...

Purpose . To compare rigid rectoscopy with three different MRI measurement techniques for rectal cancer height determination, all starting at the anal verge, in order to evaluate whether measurements from verge could be an alternative rectoscopy. Moreover, potential cut-off values categorizing tumor were evaluated.

Objective: Healthcare workers (HCWs) are particularly exposed SARS-CoV-2 because they critical in preventing viral transmission and treating COVID-19 patients. Within HCWs, personnel of intensive care units (ICUs) at the forefront patients with a severe course infection therefore represent an extremely vulnerable group. Thus, our objective is to contribute establish means control protecting HCWs frontline current pandemic. Design: An outbreak was detected contained pediatric ICU (PICU). The...
Background In order to investigate correlations between specific parameters and dental caries, it is useful record incipient dentine lesions. Aim The aim of this study was evaluate the effect a selective intensified preventive program ( SIP ) on oral health fourth graders using ICDAS . Design A cohort performed. DMFT index were recorded. Prevention social factors collected with psychometric questionnaires. test group control parallelized sociodemographic variables. Results participants in...
The aim of this study was to test the relationship between a newly developed sugar index and caries experience in 4th- 6th-graders.
BACKGROUND: Coronavirus disease-2019 (COVID-19) is a respiratory infection caused by severe acute syndrome coronavirus 2 (SARS-CoV-2). While RT-PCR assays are used routinely to diagnose active COVID-19, serological testing offers means of identifying individuals who previously experienced asymptomatic infections, as well those symptomatic infections but no longer carry the virus. METHODS: The presence SARS-CoV-2 IgG-positive antibodies in sera 673 blood donors residing south-western Germany...
Dental caries constitutes a public health challenge. As preventive strategies are desirable, this retrospective cohort study aimed to assess the experience and increment in children attending kindergartens with an early childhood (ECC) program (intervention group, IG) compared basic prophylaxis measures (control CG) located areas of different socioeconomic status (SES) within Marburg (Germany). The long-term (2009−2019) these 3−5-year-old kindergarten was evaluated. For increment, dental...
Abstract Background : During the SARS-CoV-2 pandemic, many authors have suggested a commitment of medical students to support overworked health care staff. However, whether are prepared for such an occupation remains unclear. Therefore, aim this study was evaluate students’ preparedness in pandemic and assess impact on their skills attitudes. Methods In April 2020, CoronaPreventMainz (CPM) initiated test 3300 employees with direct patient contact at University Medical Center Mainz. To...
The immediate microtensile bond strength (µTBS) of self-etch (SE) adhesives to primary dentine is promising, but evidence about the durability scarce.To assess long-term µTBS SE and examine effect 7-s etching on a 3-step etch-and-rinse (ER) adhesive.The enamel 115 caries-free human teeth was ground flat, bonding performed according group assignment: G-aenial™ Bond/GC [GB], Clearfil™ Bond/Kuraray [CS], OptiBond™ XTR/Kerr [OX], Scotchbond™ Universal/3M™ [SU], Prime&Bond® NT™/Dentsply [PB],...

Abstract Purpose In a combined in vitro/in vivo approach, tunnel vs. box-only resin composite restorations should be evaluated using thermomechanical loading (TML) vitro and restrospective clinical trial vivo. Materials methods For the part, cavities were prepared 32 extracted human third molars under simulated intraoral conditions phantom head. Specimens randomly assigned to four groups ( n = 8; 16 box-only/16 tunnel) received bonded with Amelogen Plus (box A/tunnel A) or lining Ultraseal...
Whenever intravenous (IV) access cannot be achieved in a life-threatening situation, intraosseous (IO) is the established method of choice for rapid and safe infusion therapy both adults children delivery fluids, medications, blood products (Tobias JD, Ross AK. Anesth Analg. 2010; 110(2): 391–401). IO approved "to administer any substance that infusible intravenously" (Dornhofer P, Kellar JZ, StatPearls Publishing; July 26, 2021). Nevertheless, contrast administration has rarely been used...
