Remineralisation of enamel erosive lesions by daily-use fluoride treatments: network meta-analysis of an in situ study set.

Objectives: Daily-use fluoride products are first-line protection against enamel wear from dietary-acid exposure (DAE). This study aimed to understand effects of fluoride concentration, fluoride salt, product form and ingredients in daily-use products on remineralisation and demineralisation, via network meta-analysis (NMA) of 14 studies using one well-established in-situ model. Remineralisation (surface-microhardness recovery, SHMR) after treatment, and protection against subsequent demineralisation (acid-resistance ratio, ARR) were measured.

Effect of Zinc on improving silver diamine fluoride-derived tooth discoloration in vitro.

Background: Silver Diamine Fluoride (SDF) is effective for arresting dental caries, presenting a valuable non-invasive treatment option in dentistry. Despite its therapeutic advantages, a significant drawback is the tooth discoloration that follows its application, which can affect patient acceptance. Addressing this aesthetic concern without diminishing the treatment's efficacy remains challenging in dental practice.

Trueness and adaptation of screw-retained implant-supported monolithic zirconia crowns fabricated using 3-dimensional gel deposition.

Statement Of Problem: Implant-supported monolithic zirconia restorations manufactured using the additive 3-dimensional (3D) gel deposition technique have been introduced. However, studies determining the trueness and adaptation of implant-supported crowns made with the technique are lacking.

Purpose: The purpose of this in vitro study was to evaluate the trueness and adaptation of implant-supported zirconia crowns fabricated using additive 3D gel deposition in comparison with zirconia crowns made with the widely used subtractive milling technique.

In vivo validation of osteoinductivity and biocompatibility of BMP-2 enriched calcium phosphate cement alongside retrospective description of its clinical adverse events.

Purpose: Although bone morphogenetic protein-2 (BMP-2) possesses potent osteoinductivity, there have been some concerns on the safety of BMP-2 and BMP-2-incorporated bone substitutes used for bone formation. On the other hand, BMP-2-loaded calcium phosphate cement (BMP-2@CPC) has been developed and used for bone regeneration in oral implantology. Therefore, this study aims to investigate this product's biocompatibility and clinical safety after being used in maxillofacial surgery.

Impact of dental school critical thinking demonstrations carryover to practice: Survey of 5-year graduates.

Introduction: Little literature exists on graduates' application to practice for explicit critical thinking skills learned in dental school.

Purposes: Discern the (1) degree to which graduates apply explicit critical thinking skillsets in practice; (2) degree of adaptation of critical thinking skillsets to practice; (3) frequency of use for critical thinking skillsets in practice; and (4) perceptions to improve critical thinking learning guidance in dental school.

Methods: Five critical thinking exercises/skillsets were selected that had been in place over 5 years with at least one paper: geriatrics, treatment planning, technology decision making, ethics, evidence-based dentistry; each followed concepts from an emulation model in critical thinking.

Comparison of the Efficacy of Artificial Intelligence-Powered Software in Crown Design: An In Vitro Study.

Introduction And Aims: Artificial intelligence (AI) has been adopted in the field of dental restoration. This study aimed to evaluate the time efficiency and morphological accuracy of crowns designed by two AI-powered software programs in comparison with conventional computer-aided design software.

Methods: A total of 33 clinically adapted posterior crowns were involved in the standard group.

Relationship of buccolingual inclination between the alveolar bone and first molar in different vertical facial types: A CBCT study.

Background: This study aimed to investigate the differences in the buccolingual inclination and transverse width of maxillary and mandibular first molars among different vertical facial types.

Methods: In all, 78 samples were divided into three groups based on the GoGn-SN angle: the low-angle group (n = 26, mean age=24.21±5.

Clinical evaluation of closed tray impression and intraoral scanning techniques in single posterior tissue-level implant-supported crowns: A self-controlled case study.

Statement Of Problem: Different techniques have been used to record the locations of dental implants, yet research examining the clinical outcomes of posterior implant-supported prostheses generated by different techniques, particularly concerning their fit, is lacking.

Purpose: The purpose of this self-controlled study was to evaluate the clinical outcomes of closed tray impression making and intraoral scanning for single posterior implant-supported restorations.

Material And Methods: Eighty-two participants with a single missing posterior tooth were included.

Restoration of teeth lacking complete ferrules using cast precious metal alloy post-and-cores and knife-edged crowns: A retrospective clinical study.

Statement Of Problem: While the presence of a ferrule has been reported to be essential for post-and-core restorations, many extensively damaged teeth lack complete ferrules. The outcome of post-and-core restorations for these teeth remains uncertain.

Purpose: The purpose of this retrospective clinical study was to assess the outcome of cast alloy post-and-cores and knife-edged crowns for the restoration of teeth lacking complete ferrules.

Conceptualizing patient interactions eliciting empathy, compassion, reflection, and social projection: A model with analysis.

Objectives: Conceptualizing the next patient interaction is logical, essential, and largely done intuitively with limited literature. The first objective is to elicit student thought experiences to four questions. The secondary objective is to classify responses for respective questions and to review faculty assessments.

Clinical outcomes of self-glazed zirconia veneers produced by 3D gel deposition: a retrospective study.

Background: Self-glazed zirconia (SZ) restorations are made by a novel additive three-dimensional gel deposition approach, which are suitable for a straightforward completely digital workflow. SZ has recently been used as minimally invasive veneer, but its clinical outcomes have not been clarified yet. This study aimed to evaluate the preliminary clinical outcomes of SZ veneers compared with the widely used lithium disilicate glass-ceramic veneers made by either pressing (PG) or milling (MG) process.

Characteristics of tin-containing fluoride toothpastes related to erosive tooth wear protection.

Thrombocyte-derived Dickkopf1 promotes macrophage polarization in the Bleomycin-induced lung injury model.

Immune responses are crucial to maintaining tissue homeostasis upon tissue injury. Upon various types of challenges, macrophages play a central role in regulating inflammation and tissue repair processes. While an immunomodulatory role of Wnt antagonist Dickkopf1 (DKK1) has been implicated, the role of Wnt antagonist DKK1 in regulating macrophage polarization in inflammation and the tissue repair process remains elusive.
