Comparing the efficacy of topical interventions for pain management in oral lichen planus: a time-stratified bayesian network analysis of randomized controlled trials.

Background: The evaluation of short-term pain relief provided by newly developed drugs for the treatment of oral lichen planus is currently limited. The primary aim of this study was to establish a clinically relevant hierarchy among different treatments in terms of their effectiveness for short-term pain control.

Methods: EMBASE, Scopus, PubMed, WanFang database, and Cochrane databases were searched up to January 2025.

Does an incomplete ferrule affect the fracture of endodontically treated teeth? A systematic review of in vitro studies.

Objective: The purpose of this systematic review was to assess the impact of the incomplete ferrule on the fracture of endodontically treated teeth (ETT).

Data: The keywords such as "incomplete ferrule," "ferrule," "ferrule effect," "residual dentin," "remaining dentin," or "remaining coronal dentin" were used for searching, and only in vitro studies investigating the incomplete ferrule effect on natural teeth were included.

Sources: PubMed, Medline, Embase, Cochrane Library, and Science Direct databases, and manual-searching.

Use of ceramic veneers for improving esthetics and extending the service life of an existing cement-retained implant-supported ceramic restoration: A clinical report with a 3-year follow-up.

This clinical report describes an approach for improving the esthetics and extending the service life of a cement-retained implant-supported ceramic single crown by using a ceramic veneer bonded to the conservatively prepared facial surface. The restoration satisfied the patient without removing and replacing the unesthetic implant-supported ceramic crown.

The effect of implant neck microthread design on stress distribution of peri-implant bone with different level: A finite element analysis.

Background/purpose: Significant research has proposed that the implant with microthread in the neck can significantly reduce marginal bone loss, but whether it is consistent in the condition of marginal bone loss is still unknown. The objective of this study is to investigate the effect of microthread on stress distribution in peri-implant bone with different bone level using finite element analysis.

Materials And Methods: A series of computational models of mandible segments with different bone resorption and implant models with or without microthread in the neck was installed by computer-aided design software.

Digital technologies to facilitate minimally invasive rehabilitation of a severely worn dentition: A dental technique.

This technique report describes digital technologies to facilitate minimally invasive rehabilitation with computer-aided design and computer-aided manufacturing (CAD-CAM) veneers for a severely worn dentition. The lingual veneers without tooth preparation and occlusal veneers with minimal tooth preparation were designed from the digital scan of the interim restorations. To facilitate the cementation of multiunit lingual veneers on unprepared teeth, a custom 3D-printed guide was designed from the digital cast of the natural dentition with the lingual veneers.

Evaluation of a Novel Computer Color Matching System Based on the Improved Back-Propagation Neural Network Model.

Purpose: To explore the feasibility of a novel computer color-matching (CCM) system based on the improved back-propagation neural network (BPNN) model by comparing it with the traditional visual method.

Material And Methods: Forty-three metal-ceramic specimens were fabricated by proportionally mixing porcelain powders. Thirty-nine specimens were randomly selected to train the BPNN model, while the remaining four specimens were used to test and calibrate the model.
