Different Disinfection Strategies in Bacterial and Biofilm Contamination on Dental Unit Waterlines: A Systematic Review.

Objective: The aim of this systematic review is to explore the effectiveness of different methods of reducing contamination and biofilms in dental unit waterlines (DUWLs) and to provide reference for future standardisation of disinfection practices in dental clinic.

Methods: This systematic review searched PubMed and Web of Science databases for DUWL disinfection studies from 2013 to 2023, following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and Synthesis Without Meta-analysis, additional extracting relevant data based on predefined inclusion and exclusion criteria.

Results: The study review identified 8442 articles, with 58 included after rigorous screening.

Investigation on the Effectiveness of Digital Scanning Combined with Reverse Engineering Technology in Demonstrating Full Crown Tooth Preparation.

Objective: To investigate the effect of digital scanning combined with reverse engineering technology in the demonstration of full crown tooth preparation.

Methods: Thirty-one students were randomly divided into the two groups. The students in the control group carried out traditional demonstration by the use of eye-measurement methods.

Accurate mandibular canal segmentation of dental CBCT using a two-stage 3D-UNet based segmentation framework.

Objectives: The objective of this study is to develop a deep learning (DL) model for fast and accurate mandibular canal (MC) segmentation on cone beam computed tomography (CBCT).

Methods: A total of 220 CBCT scans from dentate subjects needing oral surgery were used in this study. The segmentation ground truth is annotated and reviewed by two senior dentists.

Sicca Symptoms, Oral Health Conditions, Salivary Flow and Oral in Sjögren's Syndrome Patients.

This study aimed to investigate the relationships among sicca symptoms, oral health conditions, salivary profiles and oral Candida in Sjögren's syndrome (SS) patients. Eighty-five SS patients (mean age = 50.5) and 40 healthy non-SS individuals (mean age = 51.

A randomized, double-blind, placebo-controlled clinical trial of fluoride varnish in preventing dental caries of Sjögren's syndrome patients.

Background: Sjögren's syndrome (SS) patients are prone to caries development due to reduction of salivary flow. Topical fluoride is commonly prescribed for caries prevention.

Methods: In this 24-month randomized, double-blind, placebo-controlled clinical trial, SS patients were randomly assigned to receive either fluoride varnish or placebo gel quarterly.

[Validation of a Chinese version of the oral health impact profile-14].

Objective: To translate the original English version of oral health impact profile (OHIP)-14 into Chinese version and to test the psychometric properties of the Chinese version for use among the Chinese adults.

Methods: The original English version of OHIP-14 was translated into Chinese, and pre-tested and cross-cultural adapted. Subsequently the Chinese version with a general questionnaire was administered to adults aged 18 approximately 65 years by a trained interviewer.
