Comparative Assessment of Push-Out Bond Strength and Dentinal Tubule Penetration of Different Calcium-Silicate-Based Endodontic Sealers.

Adhesion within endodontic obturation material and root canal walls improves the efficacy of the endodontic treatment by establishing a barrier that inhibits reinfection and entombs residual bacteria. This study evaluates the push-out bond strength (POBS) of calcium silicate sealers compared to an epoxy-resin-based sealer. A total of 36 extracted mono-radicular teeth were prepared with Pro Taper Ultimate and irrigated with 5.

Dentists' stress level during the COVID-19 pandemic and their opinion on the oral health status of their patients.

Background And Aims: "Severe acute respiratory syndrome coronavirus 2" (SARS-CoV-2) is the name of the etiological agent of the pandemic Corona Virus Disease (COVID-19) which was declared on March 11, 2020 by the WHO and which affected all countries of the world, including Romania. Our study aimed to evaluate the psycho-affective implications and economic consequences for dentists in Romania during the COVID-19 (Corona Virus Disease) pandemic state of emergency and their opinion on the patients' oral health impact.

Methods: A cross-sectional observational and analytical study based on a questionnaire was conducted.

Caries Lesion Assessment Using 3D Virtual Models by Examiners with Different Degrees of Clinical Experience.

: Dental caries is a preventable, reversible disease in its early stages. This study evaluated the intra-rater agreement of International Caries Assessment and Detection System (ICDAS) scores with Medit i500 and Omnicam scanners versus traditional clinical examinations and the inter-rater agreement using the Omnicam among senior dentists and dental students and between these two groups. : A total of 24 patients aged between 21 and 34 years, randomly selected from dental students and interns, underwent four examinations (three intraoral scans and one clinical examination), and the corresponding ICDAS scores were recorded by a randomly selected rater out of the 31 available examiners.

Relationship between Behavior and Periodontal Health Self-Perception in Diabetic and Non-Diabetic Patients from Transylvania, Romania-A Self-Report Study, including The Desire to Use a Mobile App for Oral Care Improvements.

The study aimed to assess self-reported symptoms of periodontal disease (gingival bleeding, tooth mobility and halitosis) among diabetic and non-diabetic patients from Transylvania, Romania. Using statistical analysis methods, correlation between the aforementioned symptoms and diet, oral hygiene habits, stress, physical activity, and BMI (body mass index) were researched. Another secondary objective was to assess the impact of self-reported oral health, aesthetics, and halitosis on their life.

Oral health, the patients' perspective during the COVID 19 pandemic.

Background And Aims: On March 16, 2020, the state of emergency was established with drastic measures of isolation and quarantine. Among the measures taken in the context of the state of emergency was the closure of dental offices throughout the country. The aim of our questionnaire-based cross-sectional study was to identify the psycho-affective implications of the Romanian citizens induced by the COVID-19 pandemic period as well as their opinion related to the self-perceived oral health status during this period.

Mechanical Properties of Orthodontic Cements and Their Behavior in Acidic Environments.

The present research is focused on three different classes of orthodontic cements: resin composites (e.g., BracePaste); resin-modified glass ionomer RMGIC (e.

Effectiveness of Different Final Irrigation Procedures on Infected Root Canals: An In Vitro Evaluation.

This study aimed to evaluate the antibacterial effect of three final irrigation protocols and to compare their ability to remove the smear layer and debris from the root canal. Methods: Sixty-three single-rooted human teeth were inoculated with Enterococcus faecalis for 14 days. The teeth were divided into a positive control group (N = 3) and three treatment groups (N = 20) as follows: final irrigation with saline solution (control group), irrigation with 5.

Photodynamic Therapy with Natural Photosensitizers in the Management of Periodontal Disease Induced in Rats.

This study aims to investigate the effect of new natural photosensitizers (PS) (based on oregano essential oil, curcuma extract, and arnica oil) through in vitro cytotoxicity and biological tests in rat-induced periodontal disease, treated with photodynamic therapy (aPDT). The cytotoxicity of PS was performed on human dental pulp mesenchymal stem cells (dMSCs) and human keratinocyte (HaCaT) cell lines. Periodontal disease was induced by ligation of the first mandibular molar of 25 rats, which were divided into 5 groups: control group, periodontitis group, Curcuma and aPDT-treated group, oregano and aPDT-treated group, and aPDT group.

Computer-assisted identification of the gingival sulcus and periodontal epithelial junction on high-frequency ultrasound images.

Unlabelled: The primary aim of this study was to demonstrate that periodontal ultrasonography is a reliable method with which to identify and evaluate the attachment level of the gingival junctional epithelium. A secondary aim was to devise an automated computer-assisted method that allows the examiner to more easily identify the gingival sulcus contour on ultrasound images.

Material And Methods: This in vitro study was carried out on 36 sites on the lingual surface of eight pig mandibles.

Mathematical methods for assessing the prognostic of fixed partial dentures resulting from evaluating a group of dental patients in Romania.

Based on some mathematical and statistical approaches, our study leads to some conclusions concerning the procedures related to the orodental prosthetics. Occlusal equilibration in orodental prosthetics is a major issue because besides motivating patients for a regular daily oral hygiene, it could significantly increase the longevity of FPR. More dental hygiene information should be given after prosthetic treatment and patients should be motivated to attend recalls on a regular basis for professional teeth-cleaning.
