Fluorescence-aided identification technique (FIT) in retainer removal : Effects on enamel loss, composite residue, and time.

Purpose: The aim of this study was to investigate the difference in enamel loss, composite residue, and time during removal of fixed orthodontic retainers using ultraviolet (UV) light compared to standard white light.

Methods: A nickel-chromium retainer was bonded to 4 bovine teeth using a fluorescence-modified composite (Aligner Flow Composite, Voco, Cuxhaven, Germany); 20 models were created. In a split-mouth design, 2 teeth per retainer were removed using standard white light (non-FIT) and 2 teeth using the fluorescence-aided identification technique (FIT) with UV light.

The assessed parameters included anamnestic TMD symptoms (3Q/TMD), oral splint use (presence, reason, wearing habits), current stress levels (scale 1–10), current training load (hours/week), and oral health-related quality of life (OHRQoL; OHIP-G5).

[Change in the dental profession and the attitude of dental professionals towards dental care centers (ZMVZ)].

The number of dental care centers (ZMVZ) in Germany has been increasing rapidly since 2015. This new form of practice is being discussed critically, especially when run by investors. This study analyzes the opinions and attitudes towards ZMVZ of dentists practicing in Germany, focusing on age and gender differences in dentists' attitudes as well as different aspects of working for a ZMVZ.

Validity and Reliability of Intraoral Optical Coherence Tomography and Bitewing Radiography for Detecting Approximal Carious Lesions.

Introduction: This in vitro study evaluated the validity and reliability of spectral-domain optical coherence tomography (SD-OCT) to detect approximal carious lesions compared to bitewing radiography.

Methods: Forty extracted human premolars and molars with fifty-four unrestored approximal surfaces (ICDAS ll score 0-3) were mounted in a patient-equivalent simulator and imaged by digital radiography (DR) and the prototype of an intraoral OCT probe. The lesion status of the tooth surfaces was validated histologically and by microtomography (µCT).

Self-efficacy, social support and oral health-related quality of life in patients with kidney transplantation and under hemodialysis.

Background: Aim of this questionnaire-based cross-sectional study was to compare self-efficacy, social support, oral hygiene-related self-efficacy (OHRSE) and oral health-related quality of life (OHRQoL) between patients under chronic hemodialysis (HD) and patients after kidney transplantation (KTx) as well as a healthy comparison group (HC).

Methods: Patients under HD were recruited during their routine outpatient dialysis therapy, KTx patients during their maintenance appointment and HC patients during their regular dental check-up in the dental clinic. General self-efficacy, the OHRSE, social support (F-SozU-K14) and the OHRQoL (OHIP-G5) were assessed by specific validated questionnaires.

Enamel Caries Lesion Depth Obtained by Optical Coherence Tomography and Transverse Microradiography: A Comparative Study.

Introduction: Visual imaging of subsurface caries lesions is of vital interest in dentistry, which can be obtained by invasive radiography technique as well as by available non-destructive imaging approaches. Thus, as a first step toward the development of a new innovative approach, Spectral-domain optical coherence tomography (SD-OCT) was applied to detect the lesion depth in comparison to the established reference technique (transverse microradiography [TMR]).

Methods: Bovine enamel specimens were demineralized for 5 days, following previous studies.

Illustration of self-perceived knowledge, skills, and interests in undergraduate dental students using a visual metaphor- results of a monocentric cross-sectional study.

Background: Self-assessment and self-reflection of competencies are crucial skills for undergraduate students. This monocentric cross-sectional study aims to assess the self-perceived knowledge, skills and interests in conservative dentistry and periodontology of third-, fourth-, and fifth-year dental students by the Pictorial Representation of Illness and Self-measure (PRISM).

Methods: Seventy-five undergraduate dental students (n = 25 of each year) who studied between 2021 and 2022 at the Department of Cariology, Endodontology and Periodontology at the University of Leipzig, Germany, were included.

Preoperative dental screening can reduce periprosthetic infections of hip and knee endoprostheses in the first month after surgery: results of a cohort study.

Purpose: The oral cavity and, in particular, potential oral foci might pose a risk of periprosthetic joint infection (PJI). The aim of this cohort study was to determine whether practical preoperative dental screening would reduce the prevalence of early PJI in the first month after surgery.

Methods: Patients attending a specialized endoprosthesis implantation clinic between 2018 and 2022 were recruited.

Objectives: Aim of this retrospective cohort study was to evaluate whether oral health parameters would be associated with infection-related parameters and overall survival of patients with severe heart failure (HF).

Methods: Patients with severe HF, heart transplantation (HTx) and left-ventricular assist device (LVAD), which underwent a full oral examination between 2017 and 2018 were included. Infection-related and survival data were assessed from the patient´s medical records.

Effect of the Adhesive Strategy on Clinical Performance and Marginal Integrity of a Universal Adhesive in Non-Carious Cervical Lesions in a Randomized 36-Month Study.

The effectiveness of a universal adhesive applied in three application modes for the preparation of Class V composite restorations was evaluated both clinically and by quantitative marginal analysis (QMA) over 36 months. In 50 patients, three ( = 21) or four ( = 29) non-carious cervical lesions (NCCL) were restored with Venus Diamond Flow (Kulzer GmbH, Hanau, Germany). The adhesive iBond Universal (iBU, Kulzer, Germany) was used in self-etch (SE), etch-and-rinse (ER), or selective-enamel-etch mode (SEE).

Evaluation of a concept to classify anamnesis-related risk of complications and oral diseases in patients attending the clinical course in dental education.

Background: Aim of the current study was the assessment of risk classes according to a previously established system to classify the anamnesis-related risk of complications and of oral diseases in a cohort of patients attending the dental student course for dental preventive measures.

Methods: Patients attending the student course between April 2020 and December 2021 were included. To assess the medical history, a specific anamnesis tool was used, which included the classification of different potential anamneis-related risks originating from general diseases, medications or lifestyle factors into a low, moderate or high risk of complications and/or risk of oral diseases.

Dental Therapy of Patients Prior to Endoprostheses: A Retrospective, Telephone-Based Cohort Study.

The aim of this study was to assess, whether patients prior to endoprosthesis (EP) visit their dentist for need-oriented therapy and whether this would be associated with the occurrence of complications. Based on a cohort of patients, which was orally investigated prior to EP surgery between 04/2020 and 12/2021, a telephone interview was performed at least six months after EP implantation. Patients were classified into either low-risk (LR), moderate-risk (MR), or high-risk (HR) groups.
