Registries are powerful tools for the collection and distribution of valid and reliable data. The initial step in health information management is to design a minimum data set that can improve the collection of high-quality data from the registry. The present pilot study aimed to determine the optimal minimum data set for dental implants to effectively utilize at Tehran University of Medical Sciences, Tehran, Iran.

Background: Antimicrobial photodynamic therapy (aPDT) is a treatment to deal with microorganisms, which is limited to treating microbial biofilms due to poor light penetration. Sonodynamic antimicrobial chemotherapy (SACT) can be used for circumventing the limitations of aPDT to inhibit the polymicrobial biofilms. The objective of this study has been focused on the simultaneous use of aPDT and SACT, which is called photo-sonodynamic antimicrobial chemotherapy (P-SACT) to inhibit the biofilms of periopathogens bacteria on surfaces of the titanium dental implants.

In this study, we accessed the expression level of gene, as a virulence factor associated with biofilm formation, following treatment by antimicrobial photodynamic therapy (aPDT) using indocyanine green (ICG) doped with chitosan nanoparticles (CS-NPs@ICG).
Materials And Methods: CS-NPs@ICG was synthesized and examined using scanning electron microscopy (SEM).
Purpose: To compare short implants (SH; 4-8 mm) to standard implants (ST; longer than 8 mm) in edentulous jaws, evaluating pri-implant marginal bone levels (MBLs) changes, implant failures (IFs), complications, and prosthesis failures (PFs).
Materials And Methods: Electronic searches were conducted through the PubMed, Web of Science, EMBASE, Scopus, the Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov to locate all randomized controlled trials (RCTs) comparing SH to ST.

Appropriate regeneration of periodontal tissues is the primary purpose of periodontal disease treatment. The present study assessed the impact of three key regenerative elements-platelet-rich plasma (PRP), canine bone marrow mesenchymal stem cells (cBM-MSCs), and fibrin glue-on periodontal regeneration. In each of the study's five dogs, Class II furcation defects were established on the buccal surface of five teeth.
View Article and Find Full Text PDFTypically, full arch reconstruction of edentulous ridges requires five to 10 dental implants; however, some patients demanding fixed implant-supported prostheses are not able to medically or economically afford complex bone grafts and/or a greater number of implants. These situations could pivot the treatment plan toward the All-on-4 protocol. Nevertheless, due to less implant support in this treatment option, mechanical and biological complications might arise.

Background: Short implants have been proposed as an alternative for the rehabilitation of atrophic edentulous areas.
Purpose: To evaluate the efficacy of 4-mm implants vs longer implants in the atrophic posterior mandibles.
Materials And Methods: Eleven patients with bilateral atrophic mandibles were rehabilitated with two to four 4-mm implants and 10 or 8-mm long implants in augmented bone using Guided Bone Regeneration procedure.
Objectives: This study aimed to analyze functional stresses around short and long implant-supported prostheses with different crown heights.
Materials And Methods: Four three-dimensional (3D) models were designed with SolidWorks 2015. In models 1 (control) and 2, three dental implants (second premolar 4.
Background And Objective: Urokinase-plasminogen activator (uPA) is a serine protease expressed at high basal level in normal gingival cervical fluid. Despite its known pathologic role in tissue proteolysis in periodontitis, little is known concerning uPA physiological function in oral tissue. Recent evidence in cancer cells has implicated the uPA system in DNA repair and anti-apoptotic pathways.

Methods: Four identical bony defects (8 mm) were created in the calvarium of 16 New Zealand male rabbits and filled randomly with xenogenic bone substitute material (Bio-Oss®) and semelil herbal drug (ANGIPARS™). One site was filled with Bio-Oss (B); the second site was treated with ANGIPARS (A); the third site was treated with ANGIPARS + Bio-Oss (AB); and the fourth site was left as untreated control (C) and defects were left unfilled.
Introduction: A correct diagnosis and optimal treatment planning is essential for success in implant dentistry. Proper diagnosis of bone quality is an important part of the diagnostic procedure.
