Two-year evaluation of periodontal parameters following deep-margin-elevation and CAD/CAM partial lithium disilicate restorations - a prospective controlled clinical trial.

Objectives: This prospective clinical trial evaluated periodontal parameters at proximal deep-margin-elevation (DME) restoration margins 2 years after placement and compared them with baseline values and with supragingival/equigingival margins (control) on the opposite proximal surface of the same tooth.

Background: Occupational factors and the type of instrument played may influence physical and psychological health, affecting oral health-related quality of life (OHRQoL). This study assessed the prevalence of orofacial pain, sleep bruxism, stress, and OHRQoL among woodwind musicians (oboe, flute, clarinet, bassoon) in German professional orchestras, compared to cellists.

Methods: A standard online questionnaire was sent to all 129 German professional orchestras.

Recall and Oral Health Maintenance.

The aim of this chapter is to discuss current evidence and clinical protocols for recall and maintenance in patients who have undergone non-invasive and/or invasive treatment for erosive tooth wear. There is a paucity of research and evidence for some of the suggested protocols, and some sections are based on clinical experience. Recall for patients who have undergone non-invasive treatment is either for behavioural change and/or monitoring of progression of tooth wear.

Prevention and Treatment of Dental Erosion: Beyond Fluorides.

Different agents have been discussed as potential alternatives to fluoride in the prevention and treatment of erosive tooth wear (ETW). These agents may act by (1) forming an acid-protective layer on the tooth surface, such as through the use of sealants, polymers or the modification of the acquired pellicle; (2) enhancing mechanisms of (mineral) precipitation; and/or (3) preserving the organic matrix of dentine. The application of adhesives, sealants or flowables is considered to be an effective alternative to fluoride, but requires a re-sealing of the surface every several months depending on the products used.

The Role of Oral Hygiene: Does Toothbrushing Cause Harm?

Toothbrushing is considered as a prerequisite for maintaining oral health, but might also impact the process of tooth wear, particularly with regard to erosive tooth wear. Principally, the eroded surface of enamel and dentin is more prone to abrasion by toothbrushing than sound tooth surfaces. Toothbrushing conditions, such as time point of brushing after an erosive attack, toothbrushing frequency per day, and brushing force, seem of minor importance, as long as performed under conditions reflecting the clinical situation.

Vaccination rate and symptoms of long COVID among dental teams in Germany.

Although COVID-19 is no longer a global public health threat, its consequences persist, with long COVID affecting at least 10% of patients and manifesting in various organ systems. National and international health agencies promoted vaccination to enhance population immunity, prioritizing healthcare personnel due to their high occupational risk. In a previous study, we found that the risk of SARS-CoV-2 transmission among dental teams in Germany was not higher than in the general population.

Quality of Patient-Centered eHealth Information on Erosive Tooth Wear: Systematic Search and Evaluation of Websites and YouTube Videos.

Background: Due to the declining prevalence of dental caries, noncarious tooth defects such as erosive tooth wear have gained increased attention over the past decades. While patients more frequently search the internet for health-related information, the quality of patient-centered, web-based health information on erosive tooth wear is currently unknown.

Objective: This study aimed to assess the quality of patient-centered, web-based health information (websites and YouTube videos) on erosive tooth wear.

Oral health in patients with different sites of head and neck squamous cell carcinoma is not different.

Oral health might not only act as risk factor for head and neck squamous cell carcinoma (HNSCC), but might also have a predictive value for the patients' survival. Currently, information on the effect of oral health on survival of patients with different sites of HNSCC is lacking. This single-center retrospective study aimed to compare oral health in patients with different sites of HNSCC and to analyse whether oral health is associated with survival in the different subsets of HNSCC patients.
