Short-term data suggests cognitive benefits in the elderly with single-implant overdentures.

Design: This study was an extension of a randomized crossover clinical trial approved by the institutional ethics committee (approval number: D2014-148) and adhered to the CONSORT guidelines. The original study juxtaposed patient contentment with single-implant overdentures (1-IODs) against conventional complete dentures (CCDs), with patient satisfaction being the primary focus. In this follow-up study, the cognitive function of edentulous patients receiving 1-IODs was assessed, specifically monitoring for the emergence of mild cognitive impairment (MCI) throughout a three-year period.

Validity and reliability of new instruments for measuring patient satisfaction with removable dentures, Arabic Version.

Background: The psychometric properties of self-administered instruments for measuring patient satisfaction with removable dentures should be tested before inviting patients to express their opinions. This study aimed to evaluate the validity and reliability of new instruments in the Arabic language that measure patient satisfaction with all types of removable dentures.

Methods: A three-step methodology was used to translate and test the instruments.

The prevalence of novel periodontal pathogens and bacterial complexes in Stage II generalized periodontitis based on 16S rRNA next generation sequencing.

Objective: To define the subgingival microbial profile associated with Stage II generalized periodontitis using next-generation sequencing and to determine the relative abundance of novel periodontal pathogens and bacterial complexes.

Methodology: Subgingival biofilm samples were collected from 80 subjects diagnosed with Stage II generalized periodontitis. Bacterial DNA was extracted, and 16S rRNA-based bacterial profiling via next-generation sequencing was carried out.

Pathogen Reduction Technology: A Novel Possibility for Inactivation of Blood Products Used in Oral and Periodontal Surgeries.

Emergency surgical treatment has been challenging and the risk of blood contamination has been high, which is a concern among the medical and dental fraternity. The risk outweighs the benefits in these unprecedented times if proper screening and inactivation of blood products are not performed. Pathogen reduction technologies incorporate various modalities for the inactivation of blood products mainly related to blood transfusion.

Applications of Lasers in Refractory Periodontitis: A Narrative Review.

Objective: The purpose of the study is to evaluate the various lasers in dentistry and to investigate if it can be used for treatment of refractory periodontitis.

Methods: The study followed partially the PRISMA guidelines as it is a narrative review. A number of articles were selected from a period of 1980 to 2020 from databases, PubMed, PubMed central, Cochrane and Scopus.

Human dental pulp stem cells differentiation to neural cells, osteocytes and adipocytes-An study.

Human dental pulp stem cells (hDPSCs) are promising source of cells for numerous and varied regenerative medicine applications as those possess high proliferation potential with multilineage differentiation capacity compare to other sources of adult stem cells; therefore, hDPSCs could be the good source for autologous transplantation in tissue engineering and regenerative medicine. In this study stem cells were isolated from dental pulp and were characterised by flowcytometry and immunocytochemistry. The controlled cells as well as, 7-day cultured cells were positive for transcription factors, OCT 4 and SOX 2 thatconfirmed isolated cellsasmesenchymal stem cells (MSCs).

Molecular Characterization of Isolates Associated with Nasal Colonization and Environmental Contamination in Academic Dental Clinics.

To determine the genetic makeup of methicillin-sensitive/methicillin-resistant (MSSA/MRSA) from nasal colonization and environmental contamination in dental clinics. Nasal swabs from students and health care workers and environmental swabs were obtained at two academic dental clinics in the United Arab Emirates. The StaphyType DNA microarray-based assay was used for molecular characterization.

Estimation of fluoride concentration in drinking water and common beverages in United Arab Emirates (UAE).

Objective: To assess fluoride concentration in drinking water which include tap water of 4 emirates - Abu Dhabi, Dubai, Sharjah and Ajman plus bottled water, commonly available soft drinks & juices in United Arab Emirates.

Methods: Five different samples of tap water collected from each of the four emirates of UAE: Ajman, Sharjah, Abu Dhabi and Dubai; twenty-two brands of bottled water and fifteen brands of popular cold beverages, purchased from different supermarkets in U.A.

Odontogenic epithelial stem cells: hidden sources.

The ultimate goal of dental stem cell research is to construct a bioengineered tooth. Tooth formation occurs based on the well-organized reciprocal interaction of epithelial and mesenchymal cells. The dental mesenchymal stem cells are the best explored, but because the human odontogenic epithelium is lost after the completion of enamel formation, studies on these cells are scarce.

Oral health status and dental needs of autistic children and young adults.

Aim:   Children with autism might need more dental care than non-autistic, healthy children. The aims of this study were: (a) to describe the caries experience and treatment needs of autistic children aged 6-16 years in the United Arab Emirates; and (b) to provide baseline data at national and regional levels to enable comparisons and future planning of dental services for children with autism.

Methods:   All children attending a day centre in Sharjah, United Arab Emirates, for autism were selected for the study.

Do preoperative cutaneous bleeding time tests predict the outcome of intraoral surgical bleeding?

Purpose: To determine whether cutaneous bleeding time (BT) is related to perioperative bleeding outcome measures after tooth extraction. To determine whether this investigation is reliable to predict bleeding outcome after an intraoral surgical procedure.

Methods: A prospective clinical pilot study of 30 subjects.

Objective: Maxillofacial injuries constitute a substantial proportion of cases of trauma. This descriptive analytical study assesses the cause, type, incidence, demographic, and treatment data of maxillofacial fractures managed at Al Qassimi Hospital in Sharjah, United Arab Emirates, during a 4-year period and compares them with the existing body of literature on the subject.

Study Design: The medical records and radiographs of 230 patients treated for maxillofacial fractures at the Al Qassimi General Hospital over a 4-year period (from 1999 to 2002) were reviewed.

Amoxycillin with clavulanic acid and tetracycline in periodontal therapy.

The effects of tetracycline and amoxycillin with clavulanic acid on the clinical parameters and subgingival flora of eight patients with rapidly progressive periodontitis was assessed. Subjects received either tetracycline 250 mg four times daily or amoxycillin 250 mg with clavulanic acid 125 mg three times daily for a period of 2 weeks together with subgingival scaling and root planning. Both treatment regimens produced significant reductions in bleeding on probing and probing pocket depths which were still present 16 weeks after the antibiotic therapy.

Evaluation of acrylic strips containing amoxycillin with clavulanic acid for local drug delivery.

The in vitro release of amoxycillin with clavulanic acid from acrylic strips at initial concentrations of 30, 40 and 50 per cent w/w was monitored using a double-beam ultraviolet spectrophotometer and compared with release of tetracycline hydrochloride. Highest levels of the antibacterial agents were released during the first 24 h period. Therapeutic levels of the drugs continued to be released during the subsequent 9 day period and were shown to be biologically active.

Identification, and susceptibility to seven antimicrobial agents, of 61 gram-negative anaerobic rods from periodontal pockets.

Sixty-one cultures of Gram-negative anaerobic rods were isolated from deep periodontal pockets of patients with rapidly progressive periodontitis. Isolates were speciated as Bacteroides gingivalis (18 isolates), Bacteroides intermedius (8), Bacteroides oris (1), Bacteroides gracilis (17) and Fusobacterium nucleatum (17). Their susceptibilities, to seven antimicrobial agents, were determined in vitro using a plate dilution technique.
