How French dentists manage defective restorations: Evidence from ReCOL the French dental practice-based research network--A survey study.

Objectives: The objective of this study was to describe the knowledge, opinions and practices about the defective restoration (DR) management of French general dental practitioners (GDPs).

Methods: A cross-sectional, online survey-based study was carried out amongst 378 GDPs - members of the dental practice-based research network in France (ReCOL). Bivariate comparisons were made using Fisher's exact test to assess the association of the respondent characteristics (age, gender…) with the decision to repair DRs, and responses to clinical cases.

Knowledge and Opinions of French Dental Students in Operative Dentistry - Management of Deep Carious Lesions.

Purpose: A questionnaire survey was recently undertaken among French dental students (FDSs) to investigate their practices, knowledge and opinions in various domains of minimal intervention (MI) in cariology. The present work focuses on management of deep carious lesions (DCLs).

Materials And Methods: The questionnaire was administered (Spring 2018) to all the fifth-year students of the 16 French dental schools.

Periodontal disorders in a cohort of patients with Cohen syndrome.

Aims: Cohen syndrome (CS) is an uncommon autosomal recessive disorder due to mutations in vacuolar protein sorting 13B, with an intermittent presence of neutropenia. Contrary to other clinical phenotypic features, oral health has been little investigated in CS. We described oral health and dental hygiene in a cohort of CS patients.

Structural stability of DHMAI antibacterial dental composite following in vitro biological aging.

Objective: To assess the impact of the quaternary ammonium antibacterial agent, Dimethyl-Hexadecyl-Methacryloxyethyl-Ammonium Iodide (DHMAI), on structural stability of an experimental resin composite after biological aging.

Methods: Experimental resin composites containing 7.5% of DHMAI were incubated in a biological medium in the presence of a Streptococcus Mutans (SM) strain during 3 months.

Performance of Fluorescence-based Systems in Early Caries Detection: A Public Health Issue.

Aim: Modern clinical caries management involves early stage caries diagnosis and should fit with dental health policy. The objective of this study was to achieve early caries detection in enamel and dentine with a laser-based system (DIAGNOdent™ pen) first and secondary with a new fluorescence intra-oral camera (Soprolife®). A visual inspection with a loupe was used as control.

Marginal and internal fit of CAD-CAM inlay/onlay restorations: A systematic review of in vitro studies.

Statement Of Problem: Different parameters can influence the adaptation of computer-assisted design and computer-assisted manufacturing (CAD-CAM) inlay/onlay restorations. However, systematic reviews to identify and discuss these parameters are lacking.

Purpose: The purpose of this systematic review was to summarize the scientific literature investigating all parameters that can influence both the marginal and internal adaptation of CAD-CAM inlay/onlay restorations.

Effectiveness of the DHMAI monomer in the development of an antibacterial dental composite.

Objective: Development of antibacterial dental composites is the ultimate goal to decrease carious disease occurrence and increase the restoration longevity. For this purpose, the quaternary ammonium dimethyl-hexadecyl-methacryloxyethyl-ammonium iodide (DHMAI) and the methacryloyloxyethylphosphorylcholine (MPC) have been incorporated in experimental methacrylate-based composite resins. This aims to first investigate the effect of each alone and then their combined effect.

Mechanical properties and internal fit of 4 CAD-CAM block materials.

Statement Of Problem: Recent polymer-based computer-assisted design and computer-assisted manufacturing (CAD-CAM) materials have been commercialized for inlay restorations, a polymer-infiltrated ceramic-network (PICN) and composite resin nanoceramics. Little independent evidence regarding their mechanical properties exists. Internal adaptation is an important factor for the clinical success and longevity of a restoration, and data concerning this parameter for inlays made with these blocks are scarce.

Conservative approach of a symptomatic carious immature permanent tooth using a tricalcium silicate cement (Biodentine): a case report.

The restorative management of deep carious lesions and the preservation of pulp vitality of immature teeth present real challenges for dental practitioners. New tricalcium silicate cements are of interest in the treatment of such cases. This case describes the immediate management and the follow-up of an extensive carious lesion on an immature second right mandibular premolar.

Tensile and shear bond strength evaluation of a total-etch three-step and two self-etching one-step dentin bonding systems.

Purpose: The aim of this study was to compare the bond strengths of two new self-etching one-step (Prompt L-Pop 2 and Adper Prompt L-pop) to a total-etch three-step dentin bonding system (Scotchbond Multipurpose Plus).

Materials And Methods: One hundred twenty human molars were randomly divided into 3 groups of 40 specimens each. Dentin surfaces of each group were bonded with either Scotchbond Multipurpose Plus (SMP), a three-step system, Prompt L-Pop 2 (PLP), or Adper Prompt L-Pop (APLP), two one-step bonding systems--according to manufacturers' recommendations.

In vitro study of a neodynium:yttrium aluminum perovskite laser on human nonexposed pulp after cavity preparation.

Purpose: The aim of this study was to investigate dental pulp reactions after a neodynium:yttrium aluminum perovskite laser pulse on the dentinal floor of occlusal cavities in an in vitro model.

Methods: A Lokki dt laser was used at 30 Hz, 5 W, and 160 mJ for 0.5 s.
