Frankincense () Extract Effects on Growth and Biofilm Formation of , and Its Intracellular Infection in Human Gingival Epithelial Cells.

Frankincense is produced by trees, which can be found throughout the Middle East and parts of Africa and Asia. extract has been shown to have anti-cancer, anti-inflammatory, and antimicrobial effects. Periodontitis is an oral chronic inflammatory disease that affects nearly half of the US population.

Comparison of digitally assessed quality of posterior crown preparations performed with and without previous practice on patient-specific three-dimensional-printed teeth models.

Introduction: Three-dimensional (3D)-printing technology can provide customizable simulations, but its effects on patient care quality have not been well studied. This study aimed to assess the impact of practicing with patient-specific 3D-printed teeth models on the quality of patients' dental preparations performed by students transitioning to clinical training. Accordingly, the quality of posterior crown preparations was evaluated by objectively analyzing digital scans and grades in two groups: the study group, which practiced beforehand with patient-specific 3D-printed teeth models, and the control group, which did not practice with these models.

Effect of omega-3 on painful symptoms of patients with osteoarthritis of the synovial joints: systematic review and meta-analysis.

Objectives: The aim of this study was to determine the effect of omega-3 on the painful symptomatology of osteoarthritis (OA) in synovial joints.

Study Design: An electronic/manual search was conducted (2004-2019). Using pain as a primary outcome and stiffness/function and swelling as secondary outcomes, based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria, Consolidated Standards of Reporting Trials (CONSORT) reporting quality, and Cochrane/RoB-2 risk of bias assessment.

Sealing of restorations with marginal defects does not affect their longevity.

Purpose: To evaluate sealed amalgam and resin-based composite restorations after 12 years to determine whether sealing minor defects (micro-repairs) enhanced the longevity of restorations.

Methods: 34 subjects aged 18-80 were recruited. This sample group underwent 137 restorations, including 51 resin-based composite (RC) and 86 amalgam (AM) restorations.

12 Years of Repair of Amalgam and Composite Resins: A Clinical Study.

Objective: The objective of this study was to clinically evaluate repaired posterior amalgam and composite restorations over a 12 year period, investigate the influence of repair in the survival of restorations, and compare their behavior with respect to controls.

Methods: Thirty-four patients, 18 to 80 years of age with 167 restorations, 67 composite resin (RC), and 100 amalgam (AM) restorations, participated. Restorations with localized, marginal, anatomical deficiencies and/or secondary caries, and "clinically judged" suitable for repair or replacement according to US Public Health Service (USPHS) criteria, were randomly assigned to four groups: repair (n=35, 20 AM, 15 RC), replacement (n=43, 21 AM, 22 RC), positive control (n=71, 49 AM, 22 RC), or negative control (n=18, 10 AM, 8 RC).
