Oral microbiota analyses of paediatric Saudi population reveals signatures of dental caries.

Background: Oral microbiome sequencing has revealed key links between microbiome dysfunction and dental caries. However, these efforts have largely focused on Western populations, with few studies on the Middle Eastern communities. The current study aimed to identify the composition and abundance of the oral microbiota in saliva samples of children with different caries levels using machine learning approaches.

Oral microbiota analyses of Saudi sickle cell anemics with dental caries.

Objectives: The objectives of this study were to identify the composition of oral microbiota in a cohort of patients with sickle cell anemia (SCA) and a high mean number of decayed, missing, and filled permanent teeth (DMFT) and compare it to a cohort of patients with SCA and a low number of DMFT and elucidate the effect of fetal haemoglobin levels on the oral microbiota composition.

Methods: Patients who had been diagnosed with SCA, who were homozygous for sickling β-globin mutation (β/β), who had Arab-Indian haplotype, and who ranged in age from 5 to 12 years were included in this study. Oral saliva from each participant (n = 100) was collected in GeneFiX™ Saliva DNA Microbiome Collection tube and DNA was extracted using GeneFiX™ DNA Isolation Kits.

Medical Conditions, Oral Health Practices, and Barriers to Treatment among Patients Visiting a Teaching Dental Hospital in Eastern Saudi Arabia.

Objective: To assess the prevalence of medical conditions, oral hygiene practices, and dental visits among patients who attended a teaching dental hospital in Dammam, Saudi Arabia. . This retrospective cross-sectional study used patient records from 2009 to 2015 from the dental hospital of the College of Dentistry Imam Abdulrahman Bin Faisal University, Dammam.

Comparison of bacterial removal from dentinal tubules with different irrigant agitation techniques: An in vitro study.

Aim: This investigation was conducted to assess the ability of various irrigant agitation devices to eradicate from the dentinal tubules of extracted teeth.

Methodology: Fifty roots of extracted human teeth were instrumented to size 30 k with a 0.04 taper.

Effect of Photodynamic Therapy, Er,Cr:YSGG, and Nd:YAG Laser on the Push-Out Bond Strength of Fiber Post to Root Dentin.

To evaluate the push-out bond strength and modes of failure of fiber post to root dentin by using photodynamic therapy (PDT), Er,Cr:YSGG, Nd:YAG laser, and conventional cleaning and shaping (CCS). Eighty anterior teeth were sectioned in a horizontal manner being 2 mm incisal to the cementoenamel junction, and root canal was prepared for post space. After post space was made, fiber posts were placed inside the root canal system.

Effect of photodynamic therapy and ErCrYSGG laser irradiation on the push-out bond strength between fiber post and root dentin.

Background: To evaluate the push out bond strength and modes of failure of fiber post by using photodynamic therapy (PDT), Er,Cr:YSGG laser and conventional cleaning and shaping (CCS).

Methods: Sixty maxillary anterior teeth were sectioned horizontaly 2 mm incisal to the cemento-enamel junction, and root canal were prepared for post space. Tapered fiber posts were placed inside the root canal after post space was made.

Efficacy of phototherapy in the adhesive bonding of different dental posts to root dentin: A systematic review.

Background: The aim of the current systematic review was to evaluate the efficacy of phototherapy in the adhesive bonding of different dental posts to root dentin.

Methods: The outline of this systematic review followed the PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analysis) guidelines. Searches in both electronic and manual literature were performed in the main databases 'MEDLINE' and 'EMBASE' up to March 2019 using the following terms: (Phototherapy) AND (push out test) AND (bond strength) AND (post) OR (fibre) OR (metal) AND (smear layer).

Current weight of evidence of viruses associated with peri-implantitis and peri-implant health: A systematic review and meta-analysis.

The pathological role of human herpesviruses (HHVs) (Epstein-Barr virus [EBV], Human cytomegalovirus [CMV], and Herpes simplex virus [HSV]) in peri-implant health needs clarification quantitatively. To determine the weight of evidence for HHVs in patients with peri-implantitis (PI) and substantiate the significance of HHVs in peri-implant inflammation, electronic databases including EMBASE, MEDLINE, Cochrane Oral Health Group Trials Register, and Cochrane Central Register of Controlled Trials were searched from 1964 up to and including November 2018. Meta-analyses were conducted for prevalence of HHVs in PI and healthy controls.

Is phototherapy effective in the management of post-operative endodontic pain? A systematic review of randomized controlled clinical trials.

Background: The aim of the current review was to answer the P.I.C.

Bacterial flora of dental periradicular lesions analyzed by the 454-pyrosequencing technology.

Introduction: Symptomatic teeth with periradicular lesions of infectious origin remain a significant challenge in dentistry, and the reason for the acute perturbation is incompletely understood. The present study used pyrosequencing of bacterial 16S ribosomal RNA (rRNA) genes to characterize the microbiota of periradicular lesions.

Methods: Thirteen periradicular lesions from 11 symptomatic and 2 asymptomatic teeth were sampled during apical surgery.
