Influence of dental prophylaxis procedures on the tooth veneer interface in resin-based composite and polymer-infiltrated ceramic veneer restorations: an in vitro study.

Objectives: The aim of this study was to investigate the influence of dental prophylaxis cleaning procedures and artificial aging on veneers in human teeth. The external marginal and internal tooth veneer as well as the restoration surfaces were examined.

Material And Methods: Thirty-two extracted premolars were restored with resin-based composite (RBC) and polymer-infiltrated ceramic network (PICN) veneers.

Clinical findings and self-reported oral health status of biathletes and cross-country skiers in the preseason - a cohort study with a control group.

This cross-sectional study aimed to compare clinical oral conditions as well as the self-reported oral health status of biathletes and cross-country skiers (A) to age- and gender-matched non-athletic controls (C). Thirty-one A and 68 C were examined in 2020 regarding caries experience (DMF-T), partially erupted wisdom teeth, non-carious tooth wear (erosion), dental plaque biofilm, gingival inflammation, periodontal screening (PSI), salivary active matrix-metalloproteinase-8 (aMMP-8) test and screening for temporomandibular disorders (TMD). Questionnaires recorded periodontal symptoms, TMD symptoms and oral health behaviour.

Clinical and OCT assessment of application modes of a universal adhesive in a 12-month RCT.

Objectives: To evaluate a universal adhesive clinically using FDI criteria and by optical coherence tomography (OCT).

Methods: In 50 patients, three or four non-carious cervical lesions (NCCL) were restored with composite (Venus® Diamond Flow, Kulzer) using iBond® Universal (iBU, Kulzer) applied in self-etch (iBU-SE, n = 50), selective-enamel-etch (iBU-SEE, n = 29) or etch-and-rinse mode (iBU-ER, n = 50) and the reference OptiBond™ FL (OFL, Kerr, n = 50). Restorations were imaged by SD-OCT.

Orofacial conditions and oral health behavior of young athletes: A comparison of amateur and competitive sports.

Purpose: This retrospective cross-sectional study aimed to evaluate oral health status (dental, periodontal, and functional) and oral health behavior in young German athletes including the comparison of competitive (CA) and amateur sports (AA).

Methods: Data of CA (German national teams, perspective, and youth squads) and AA aged between 18 and 30 years with an available oral examination in 2019 were included.

Clinical Examination: caries experience (DMF-T), non-carious wear (erosion, BEWE), partially erupted wisdom teeth, gingival inflammation (PBI), plaque index, periodontal screening (PSI), and temporomandibular dysfunction (TMD) screening.

Assessibility of different CAD/CAM ceramics with optical coherence tomography.

Objectives: To investigate the light penetration depth of various CAD/CAM ceramics and luting agents by spectral-domain optical coherence tomography (SD-OCT).

Methods: Six CAD/CAM ceramics: lithium disilicate (LS2), zirconia-reinforced lithium silicate (ZLS), lithium aluminosilicate (LAS), polymer infiltrated (PIC), feldspar (FEL) and zirconium oxide (ZRO) and five common luting agents, two self-adhesive and three adhesive materials, were included. SD-OCT wavelengths (1310/1550 nm) and frequencies (5/28 kHz) that are particularly suitable for these materials were investigated.

Associated factors to caries experience of children undergoing general anaesthesia and treatment needs characteristics over a 10 year period.

Background: Aim of this study was to describe the characteristics of 1- to 6-year-old children who underwent general anesthesia (GA) in a German specialized pediatric dental institution between 2002 and 2011, and to evaluate the risk factors (age, migration background, nutritional status) for caries experience (dmf-s) in these children.

Methods: A cross-sectional study with retrospective data collection was designed. Children who underwent comprehensive dental treatment under GA were enrolled in the study.

Comprehensive Assessment of Orofacial Health and Disease Related Parameters in Adolescents with Juvenile Idiopathic Arthritis-A Cross-Sectional Study.

Background: The aim of this cross-sectional study was to investigate oral health and functional status of adolescents with juvenile idiopathic arthritis (JIA) and its possible link to disease specific parameters.

Methods: Patients with JIA were recruited (November 2012-October 2014) and disease specific information was extracted from patients' records. Oral examination included: dental findings (decayed-, missing- and filled-teeth-index (dmf-t/DMF-T)), gingival inflammation (papilla-bleeding-index (PBI)) and periodontal screening index (PSI).
