Comparison of Direct Intraoral Scan and Traditional Impression for CAD/CAM Mandibular Overdenture Base: RCT on Peri-implant Marginal Bone Changes.

Aim: This study aimed to evaluate the impact of digital vs traditional impression techniques on peri-implant vertical bone resorption in the creation of mandibular overdenture bases supported by four implants using CAD/CAM technology.

Materials And Methods: Twenty edentulous patients were placed in four mandibular implants and randomly divided into groups: (A) the control group (CIG) ( = 10); patients obtained CAD/CAM denture base using conventional impression technique and group (B) the study (DIG) group ( = 10); patients obtained CAD/CAM denture base using digital impression technique. Peri-implant vertical bone height was measured immediately (T0), 6 (T6), and 12 (T12) months after insertion.

Radiographic Assessment of Three-implant-retained Mandibular Overdentures: A Clinical Study of Alveolar Bone Height Changes (Randomized Clinical Trial).

Aim: To evaluate the residual alveolar ridge bone height changes regarding the impact of the block-out spacer used during the pick-up procedures of implant-assisted mandibular complete overdentures.

Materials And Methods: This study was a randomized clinical trial conducted on 18 patients. All patients received three mandibular dental implants with definitive locator attachments which were directly picked up with two different techniques.

Comparison of Histidine rich glycoprotein, a novel biomarker for sepsis, with traditional biomarkers in adult ICU patients.

Sepsis is a major public healthcare problem. It remains a significant cause of morbidity and mortality in intensive care units (ICU) all over the world. A lifesaving early specific diagnosis and treatment is a challenge as no gold standard technique exists that can alone allow a rapid and reliable diagnosis of sepsis.

Prevalence and molecular characterization of foodborne and human-derived Salmonella strains for resistance to critically important antibiotics.

The primary goals of this cross-sectional study were to screen various food/water, and human samples for the presence of Salmonella species, and to assess the phenotypic and genetic relationship between resistances found in food and human Salmonella isolates to critically important antibiotics. Between November 2019 and May 2021, 501 samples were randomly collected for Salmonella isolation and identification using standard culturing methods, biochemical, matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) and PCR techniques. Antimicrobial susceptibility testing was performed on confirmed Salmonella species, and PCR was used to investigate the genetic components that confer these resistance traits.

The role of cytokine gene single nucleotide polymorphism in the development of recurrent acute otitis media.

The study aimed at examining the role of single nucleotide polymorphism (SNP) of cytokine genes in the development of recurrent acute otitis media (AOM) among children. Single nucleotide polymorphism of IFN-, IL-6, IL-10, TNF-α, and TGF-β1, were analyzed by the polymerase chain reaction with sequence-specific primers (PCR-SSP) in 82 children with recurrent AOM and compared with a similar control group. There was a significant higher incidence of IL-10 polymorphisms (loci -592, -819 and -1082) in children with recurrent AOM (P=0.

Hand hygiene initiative: comparative study of pre- and postintervention outcomes.

Background: Adequate hand hygiene is considered the most effective measure to reduce transmission of nosocomial pathogens.

Aims: To determine the effectiveness of infection control intervention to improve compliance with hand hygiene in the Emergency Department, Al-Leith General Hospital, Saudi Arabia, and evaluate bacterial load on hands as a possible indicator of improvement.

Methods: The study consisted of 3 phases: Phase I, measurement of basal hand hygiene compliance level; Phase II, multimodal hand hygiene educational programme was initiated; and Phase III, hand hygiene compliance level was measured again.

Clips vs Resilient Liners Used With Bilateral Posterior Prefabricated Bars for Retaining Four Implant-Supported Mandibular Overdentures.

The objective of this research was to clinically compare peri-implant tissue health of bar-clips vs silicone-resilient liners used with bilateral posterior bars for retaining 4 implant-supported mandibular overdentures. Thirty completely edentulous male patients (mean age, 65 years) were randomly assigned into 2 equal groups. Each patient received 4 implants in the canine and first molar regions of the mandible using a flapless surgical technique.

Strains Around Abutment Teeth with Different Attachments Used for Implant-Assisted Distal Extension Partial Overdentures: An In Vitro Study.

Purpose: The aim of this study was to evaluate and compare strain around abutment teeth with different attachments used for implant-assisted distal extension partial overdentures (IADEPODs).

Materials And Methods: A mandibular Kennedy class I acrylic model (remaining teeth from first premolar to first premolar) was constructed. A conventional partial denture was constructed over the model (control, group 1).

Study of non-organ-specific antibodies in children with genotype 4 chronic hepatitis C.

Background/aim: Adult studies established a relationship between hepatitis C virus (HCV) infection and the presence of non-organ-specific antibodies (NOSAs). Most studies were carried out on genotypes 1 and 2. Only a few studies addressed that issue in pediatrics.

Scanning electron microscopy observations of osseointegration failures of dental implants that support mandibular overdentures.

Aim: : Investigating possible failure causes of mandibular implants after their immediate loading with an overdenture retained with bilateral bar attachments, using scanning electron microscope.

Patients And Methods: Twenty edentulous male patients were included in the present study. Each patient had 2 fixtures inserted in the canine and the first molar areas on each side of the mandible.

A comparison of mandibular denture base deformation with different impression techniques for implant overdentures.

Purpose: This study aimed to evaluate mandibular denture base deformation along with three impression techniques used for implant-retained overdenture.

Materials And Methods: Ten edentulous patients (five men and five women) received two implants in the canine region of the mandible and three duplicate mandibular overdentures which were constructed with mucostatic, selective pressure, and definitive pressure impression techniques. Ball abutments and respective gold matrices were used to connect the overdentures to the implants.

Marginal bone loss adjacent to conventional and immediate loaded two implants supporting a ball-retained mandibular overdenture: a 3-year randomized clinical trial.

Objectives: The aim of this study was to evaluate and compare marginal bone loss and clinical outcomes of conventionally and immediately loaded two implants supporting a ball-retained mandibular overdenture.

Materials And Methods: Thirty six completely edentulous patients (22 males and 14 females) were randomly assigned into two groups. Each patient received two implants in the canine area of the mandible after a minimal flap reflection.
