Quality of Life in Patients with Endodontically Treated Teeth: A Retrospective Study at an Educational Hospital.

Background/objectives: Root canal treatment (RCT) is a crucial procedure for preserving dental health. While its clinical success rates are well documented, patient-reported outcomes regarding quality of life remain less explored. This study aimed to assess the long-term impact of RCT performed in an educational hospital on patients' oral-health-related quality of life (OHRQoL) using the Oral Health Impact Profile-14 (OHIP-14).

Antibiofilm efficacy of a calcium silicate-based intracanal medicament against Fusobacterium nucleatum strains.

This study evaluated the antibiofilm efficacy of a calcium silicate-based intracanal medicament (Bio-C Temp) against Fusobacterium nucleatum (F. nucleatum). Dentin slices (n = 88) were inoculated with F.

Efficacy of various techniques in calcium silicate-based intracanal medicament removal: a micro-CT analysis.

The purpose of this study was to evaluate the efficacy of different techniques in removing calcium silicate intracanal medicament (Bio-C Temp). Forty human single-canaled premolars were randomly distributed into five groups (n = 8). All root canals were instrumented, then filled with Bio-C Temp.

Effect of bioceramic intracanal medication on the dentinal bond strength of bioceramic cements: an study.

Background: The present study evaluated the effect of a bioceramic intracanal medicament (Bio-C Temp) on the push-out bond strength of bioceramic cements.

Methods: Forty-eight human single-canaled premolars were prepared and randomly divided into three groups: Group (A) received no intracanal medicament; Group (B) calcium hydroxide (CH); and Group (C) Bio-C Temp. After medicament removal, the roots were sectioned transversely.

Effect of sodium hypochlorite temperature and concentration on the fracture resistance of root dentin.

Background: Sodium hypochlorite (NaOCl) is the most efficient root canal irrigant to date. The aim of this study was to compare the effect of NaOCl used at different temperatures and concentrations on the compressive strength of root dentin.

Materials And Methods: Seventy-two extracted human single-canaled straight roots of comparable size and length were selected and randomly divided into six groups (n = 12): Group (A) served as a control with unprepared canals.

Prevalence of bone loss surrounding dental implants as detected in cone beam computed tomography: a cross-sectional study.

Objectives: The objective of this study was to assess the prevalence of crestal, and apical bone loss (CBL & ABL) associated with dental implants in CBCT scans. The second objective was to assess the radiographic stage of implant disease and the visible predisposing factors.

Materials And Methods: The CBCT scans that were taken from January 2015 to January 2022 in King Saud Medical City were screened to examine the marginal and periapical condition of dental implants.

Assessment of the effect of spacer material on gap and void formation in an endodontic temporary restoration using micro-computed tomography.

This study aimed to evaluate the effect of two spacer materials (cotton pellet and polytetrafluoroethylene [PTFE]) on gap and void formation in the Cavit restoration used for endodontic temporization. Thirty-four extracted human single-rooted premolars were matched and allocated into two groups (n = 17/group) according to the access cavity spacer (cotton pellet or PTFE). Standardized endodontic access cavities were prepared in all the teeth.

Bacterial infiltration and detorque at the implant abutment morse taper interface after masticatory simulation.

This study evaluated the bacterial infiltration and the detorque of indexed and non-indexed abutments of Morse taper implants (MTI) after mechanical cycling (MC). 40 MTI were distributed into four groups: IIA (indexed implant abutments); NIIA (non-indexed implant abutments); IIAMC (indexed implant abutments submitted to MC); NIIAMC (non-indexed implant abutments submitted to MC), which were carried out under one million 5 Hz frequency and 3 Bar pressure. After mechanical cycling, all groups were immersed in a bacterial solution in Brain Heart Infusion Agar.

Self-Reported Periodontal Disease and Its Association with SARS-CoV-2 Infection.

: Knowledge of the oral manifestations associated with SARS-CoV-2 infection, the new coronavirus causing the COVID-19 pandemic, was hindered due to the restrictions issued to avoid proximity between people and to stop the rapid spread of the disease, which ultimately results in a hyperinflammatory cytokine storm that can cause death. Because periodontal disease is one of the most frequent inflammatory diseases of the oral cavity, various theories have emerged postulating periodontal disease as a risk factor for developing severe complications associated with COVID-19. This motivated various studies to integrate questions related to periodontal status.

Use of Water by Schoolchildren: Impact of Indirectly Supervised Daily Toothbrushing-A Pilot Study.

Aim: This present longitudinal, quantitative, and analytical pilot study evaluated the impact of daily indirectly supervised toothbrushing on water consumption.

Materials And Methods: The study was carried out in a social center that provided care to children aged 5-14 years in Campinas in the state of São Paulo. Calibrated hydrometers were installed on taps used by the children, and the daily volume of water used was measured for 25 school days (T0).

Perception of midline deviations in smile esthetics by laypersons.

Objective:: To evaluate the esthetic perception of upper dental midline deviation by laypersons and if adjacent structures influence their judgment.

Methods:: An album with 12 randomly distributed frontal view photographs of the smile of a woman with the midline digitally deviated was evaluated by 95 laypersons. The frontal view smiling photograph was modified to create from 1 mm to 5 mm deviations in the upper midline to the left side.

Upper airway dimensions in patients undergoing orthognathic surgery: a systematic review and meta-analysis.

The objective of this systematic review was to evaluate the effect of different types of orthognathic surgery on the dimensions of the upper airways assessed using three-dimensional images. An electronic search was performed in Cochrane Library, Medline, Scopus, VHL, Web of Science, and the System for Information on Grey Literature in Europe, ending January 2015. Inclusion criteria encompassed clinical studies in humans, patient age >15 years, patients submitted to maxillary or mandibular advancement or setback surgery, isolated or in combination, and presentation of airway measures, specifically volume and/or minimum cross-sectional area (CSA), obtained from computed tomography or magnetic resonance imaging.

Prevalence of Oral and Maxillofacial Trauma in Elders Admitted to a Reference Hospital in Northeastern Brazil.

Objective: To know the prevalence and etiology of oral and maxillofacial trauma in elders.

Methods: Analytical quantitative cross-sectional study conducted at a public trauma hospital located in Fortaleza-Ceará, Brazil. The study population comprised patients with trauma who were hospitalized from April to August 2014.

Impact of pedagogical method on Brazilian dental students' waste management practice.

The purpose of this study was to conduct a qualitative analysis of waste management practices among a group of Brazilian dental students (n=64) before and after implementing two different pedagogical methods: 1) the students attended a two-hour lecture based on World Health Organization standards; and 2) the students applied the lessons learned in an organized group setting aimed toward raising their awareness about socioenvironmental issues related to waste. All eligible students participated, and the students' learning was evaluated through their answers to a series of essay questions, which were quantitatively measured. Afterwards, the impact of the pedagogical approaches was compared by means of qualitative categorization of wastes generated in clinical activities.
