Progressive Pre-Eruptive Coronal Resorption Associated With Enamel Degeneration: A Case Series.

The purpose of this article is to present three cases of a rare phenomenon called pre-eruptive coronal resorption (PCR), which occurs in teeth with enamel degeneration. In the first case, the enamel defects occurred due to ectodermal dysplasia, which represents the first documented case of a patient with ectodermal dysplasia who underwent PCR. In the other two cases, the enamel defects occurred due to amelogenesis imperfecta.

Qualitative and quantitative assessment of infraoccluded deciduous teeth: a systematic review.

Background: Infraocclusion of deciduous teeth is a frequent dental anomaly caused by ankylosis accompanied by local growth disturbance. During puberal growth spurt an increasing progression of infraocclusion is detected. The clinical classification of ankylosed deciduous teeth varies considerably among scientific studies.

Purpose: Diagnosing and treating obstructive sleep apnea (OSA) requires fundamental understanding of sleep medicine, including training and clinical experience. So far, dental sleep medicine (DSM) has not yet become a mandatory part of dental education in Germany. This questionnaire-based survey for both lecturers and students aimed to evaluate DSM education among undergraduate students.

[Assessment of carious dental lesions and treatment options: comparison of the knowledge of dental students and orthodontic assistants].

In order to optimize dental education, established procedures for caries diagnosis and therapy, such as the International Caries Classification and Management System (ICCMS), should be integrated into the curriculum. In preparation, the level of knowledge of dental students on caries detection and management was surveyed in order to specifically address deficits in dental teaching. In addition, the data were compared with the knowledge of clinically experienced dentists.

Detection of Erosive Changes on Smooth Surfaces with and without Orthodontic Brackets Using an Intraoral Scanner-An In Vitro Study.

This study aimed to evaluate the suitability of an intraoral scanner (IOS) for detection of erosive changes on smooth surfaces adjacent to orthodontic brackets.

Systematic review and meta-analysis on the effect of self-assembling peptide P-4 on arrest, cavitation, and progression of initial caries lesions.

Background: Simple noninvasive evidence-based interventions for caries are needed to overcome limitations in the restorative paradigm. The self-assembling peptide P-4 is a noninvasive intervention that regenerates enamel in initial caries lesions.

Studies Reviewed: The authors conducted a systematic review and meta-analysis on the effectiveness of the P-4 products Curodont Repair (Credentis; now manufactured by vVARDIS) (CR) and Curodont Repair Fluoride Plus (Credentis; now manufactured by vVARDIS) on initial caries lesions.

Ability of a Blue Hemoglobin-Based Liquid as a Novel Technology to Stain Initial Enamel Demineralization: A Proof-of-Concept in vitro Study.

During orthodontic treatment, enamel demineralization can occur. Its early detection is the basis for efficient preventive measures to arrest or remineralize lesions. In the present study, the application of a novel blue hemoglobin-based liquid (BlueCheck) was evaluated as proof of concept for detection of artificially demineralized smooth surfaces.

Remineralisation capability of silver diamine fluoride in artificial enamel lesions on smooth surfaces using quantitative light-induced fluorescence measurements in-vitro.

Enamel demineralisation can develop on smooth surfaces as an undesirable side effect during orthodontic treatment with fixed appliances. This study aimed to evaluate the ability of 38% silver diamine fluoride in remineralisation (as estimated by fluorescence gain) of artificial initial lesions in smooth surfaces of human enamel. The smooth surfaces of 50 human tooth samples were artificially demineralised and 45 samples were allocated randomly into three groups receiving a single treatment with a varnish: group I: Riva Star (silver diamine fluoride, SDF), group II: Bifluorid 12 (NaF, CaF), and group III: Cervitec F (CHX, CPC, NHF).

Knowledge of undergraduate dental students regarding management of caries lesions.

Objectives: Understanding of lifelong control of disease processes associated with caries and its management is an essential part of dental education. This study evaluated the dental students' knowledge of caries diagnosis and management using the International Caries Classification and Management System (ICCMS).

Methods: A survey was conducted among undergraduate dental students at two dental schools, attending the sixth (centre 1) and seventh semester (centre 2), respectively.

Agreement of Bioluminescence Measurements and Visual Assessment in Monitoring Occlusal Surfaces of Permanent Teeth.

Background: Caries lesion activity is typically assessed by visual-tactile criteria. Regular monitoring is required to detect the transition of lesions and to ensure that the initial assessment was valid. This clinical study aimed to evaluate the agreement of bioluminescence measurements (Calcivis imaging system, Cis) with visual examination to assess caries lesion activity and to monitor occlusal surfaces.

Use of bioluminescence measurements for detection of artificial demineralization adjacent to orthodontic brackets.

Purpose: Enamel demineralization can occur as a side effect during orthodontic treatment with fixed appliances and should be detected as early as possible. A new approach to assess demineralization is a system consisting of a photosensitive protein that binds to free calcium ions at the enamel surface. A camera is then used to visualize the bioluminescence spots.

Aim: To provide recommendations for dental clinicians for the management of dental caries in older adults with special emphasis on root caries lesions.

Methods: A consensus workshop followed by a Delphi consensus process were conducted with an expert panel nominated by ORCA, EFCD, and DGZ boards. Based on a systematic review of the literature, as well as non-systematic literature search, recommendations for clinicians were developed and consented in a two-stage Delphi process.

Impact of self-assembling peptides in remineralisation of artificial early enamel lesions adjacent to orthodontic brackets.

Enamel demineralisation can occur as a side effect during orthodontic treatment with fixed appliances.
