Exploring the relationship of salivary pH and flow rate with tooth wear severity: A cross-sectional study.

Background: Tooth wear is the loss of dental hard tissue due to chemical and mechanical processes, and its prevalence ranges from 13 to 80 % in the general population. Management depends on understanding potential risk factors; however, the role of saliva as one of them is not completely understood. The aim of this study was to explore the relationship between salivary pH and flow, and tooth wear in patients referred to a specialized dental clinic for tooth wear management.

Do randomised clinical trials on dental caries adopt Open Science practices?

Background: Open Science Practices (OSPs) are essential when assessing research integrity and quality of Randomised Clinical Trials (RCTs). As dental caries represents a significant oral health burden, our objective was to identify and analyse the adoption of OSPs within RCTs focused on addressing this disease.

Methods: We searched PubMed to retrieve RCTs related to dental caries published from January 2000 to March 2022.

Are open science practices in dentistry associated with higher Altmetric scores and citation rates?

Aim: Open science, a set of principles and practices, aims to make scientific research more accessible and accountable, benefiting scientists and society. This study evaluated whether adopting open science practices (OSPs) correlates with higher citation rates and Altmetric scores.

Methods: A random sample of randomised clinical trials (RCTs) on dental caries published between 2000 and 2022 was selected.

[Time wears on everyone, but not equally quickly].

In 30 patients (average age 38 ± 8 years, 77% male, 23% female) with intra-oral scans made at intake and after 3 years, tooth wear progression was measured. With the aid of GeoMagic to superimpose the scans, the maximum difference in height of 64 surfaces was measured per surface. A large variation was found in progression rates between patients, between various teeth in a single mouth, and between surfaces on a single tooth.

Tooth wear and bruxism: A scoping review.

Objective: This study presents a scoping review to determine the association between tooth wear and bruxism.

Challenges in conducting clinical research in primary care dentistry.

The integration of dentistry into primary health care is crucial for promoting patient well-being. However, clinical studies in dentistry face challenges, including issues with study design, transparency, and relevance to primary care. Clinical trials in dentistry often focus on specific issues with strict eligibility criteria, limiting the generalizability of findings.

5.5-year-survival of CAD/CAM resin-based composite restorations in severe tooth wear patients.

Objectives: Aim of this prospective study was to assess full mouth rehabilitation of severe tooth wear patients using minimally invasive CAD/CAM resin-based composite (RBC) restorations and direct veneers by evaluating restoration survival up to 5.5-years.

Methods: Twenty-two patients with generalized severe tooth wear with functional and/or esthetic problems were included.

Single crown vs. composite for glass fiber post-retained restorations: An 8-year randomized clinical trial.

Objectives: This study aimed to compare the success and survival rates of metal-ceramic crowns and composite resin restorations applied in root filled teeth that received a glass fiber post.

Methods: A prospective, randomized controlled trial, with equivalent parallel groups was designed. Eighty-two teeth were randomly allocated to the metal-ceramic or composite resin groups.

Inter- and intra-variability in tooth wear progression at surface-, tooth- and patient-level over a period of three years: A cohort study: Inter- and intra-variation in tooth wear progression.

Objective: To explore the variability of tooth wear progression at the surface-, tooth- and patient-level over a period of three years three years using in vivo 3D-measurements of full dentitions amongst patients with moderate to severe tooth wear and without demand for restorative rehabilitation.

Methods: Fifty-five eligible patients with moderate to severe tooth wear had intra-oral scans taken using either the 3 M True Definition Intraoral Scanner or the 3 M Lava Chairside Oral Scanner. The maximum height loss (µm) per cusp/incisal/palatal surface at unrestored surfaces was measured using the 3D Wear Analysis (3DWA)-protocol with Geomagic Qualify, resulting in sixty-four measurements per dentition.

Association between salivary characteristics and tooth wear: A systematic review and meta-analysis.

Objective: Literature was systematically reviewed to identify salivary characteristics and their association with tooth wear.

Data: A protocol was developed a priori (PROSPERO CRD42022338590). Established systematic review methods were used for screening, data extraction, and synthesis.

Long term clinical performance of 'open sandwich' and 'total-etch' Class II composite resin restorations showing proximal deterioration of glass-ionomer cement.

Objectives: To compare clinical performance of resin composite posterior Class-II restorations placed with etch-and-rinse adhesive or open sandwich technique using glass-ionomer cement.

Methods: Data on Class II restorations placed by one dentist between 1990 and 2016 were collected from patient files, including caries risk, tooth related variables, applied materials and dates of last check-up visit and restoration placement. Open sandwich restorations were placed before 2001, while after 2001, a total-etch technique using etch-and-rinse 3-step adhesive was used when placing a Class II composite restoration.

Managing tooth wear with respect to quality of life: an evidence-based decision on when to intervene.

Patients with more severe forms of tooth wear may require restorative rehabilitation. The decision to commence treatment must be taken carefully and there are a multitude of factors to consider. Alongside the clinical signs and symptoms typically associated with tooth wear, there is also the need to assess the impact of the condition on the patient's oral health-related quality of life.

Survival rate and treatment success of glass fiber posts cemented with two adhesive cementation strategies after up to 106 months: a randomized clinical trial.

Objectives: The objective of this study is to evaluate the longevity of two fiber post cementation strategies in a prospective, multicenter, non-inferiority, double-blind randomized controlled trial.

Methods: A total of 152 teeth, with adequate endodontic treatment and loss of coronal structure and bilateral simultaneous posterior occlusal contacts, were randomly allocated to receive glass fiber posts cemented with a conventional cementation strategy (CRC group: adhesive system + resin cement) (Adper Single Bond + RelyX ARC; 3 M-ESPE) or a self-adhesive cementation strategy (SRC group: self-adhesive resin cement; RelyX U100/U200; 3 M-ESPE). The patients were recalled annually for clinical and radiographical evaluation with a 93% recall rate (142 teeth, with 74 at CR groups and 68 at SRC group).
