Approaches to regenerative endodontic therapy in necrotic human teeth with complete root formation: a systematic review.

Introduction: Regenerative endodontic procedures (REPs) aim to replace damaged dental structures and regenerate the dentin-pulp complex. Initially focused on teeth with incomplete root formation, recent research shows promise for necrotic teeth with complete root formation.

Methodology: This review, following PRISMA guidelines and registered in PROSPERO, included clinical studies on regenerative endodontic therapy in necrotic human teeth with complete root formation.

Cytotoxicity and Bioactivity of Calcium Silicate-based Cements in a Culture of Stem Cells from the Apical Papilla.

Introduction: The present study evaluated the cytotoxicity and bioactivity of commonly-used calcium silicate-based cements in a culture of stem cells from the apical papilla (SCAPs).

Materials And Methods: NeoMTA Plus (Avalon Biomed), Biodentine (Septodont) and MTA HP Repair (Angelus) cements were evaluated using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) and sulphorhodamine-B (SRB) viability assays. Cells were seeded (1*10 cells mL) in 96-well plates and exposed to 1:4 diluted extract in 24 h and 72 h.

Subaxial spine arthrodesis in patients with spine fractures and facet joint dislocations: Is magnetic resonance imaging required to determine the optimal surgical approach?

Background: The medical literature suggests that facet dislocations (FDs) must be managed surgically, even in the absence of spinal cord injury. In fact, there is no standard guideline for managing FD cases and whether magnetic resonance imaging (MRI) should be utilized for optimizing treatment planning.

Methods: Fifteen cases of FD were evaluated twice by nine spine surgeons.

Nanoneedle-like zinc oxide as a filler particle for an experimental adhesive resin.

Aim: The aim of this study was to develop an experimental adhesive resin with nanoneedle-like zinc oxide (N-ZnO), an inorganic filler, that could avoid particle agglomeration and lead to a homogeneous stress distribution within the material and characterize it.

Materials And Methods: N-ZnO particles obtained by a thermal evaporation technique were characterized regarding size and surface area and added at 0 (control), 1, 2, 5, and 10 wt%, to an experimental adhesive resin. The following experimental adhesive resins' properties were assessed: radiopacity, contact angle to conditioned enamel and dentin, color, degree of conversion, flexural strength, resistance to degradation, and cytotoxicity.

Analysis of Cyto- and Genotoxicity of Barbatimão Extract on Human Keratinocytes and Fibroblasts.

Barbatimão (, Mart.) is a native Brazilian species used in traditional medicine and some commercial preparations owing to its strong wound-healing activity. However, controversy regarding its use due to safety concerns over the potential genotoxic effect of this plant remains.

Surgery in ovarian cancer - Brazilian Society of Surgical Oncology consensus.

Unlabelled: Surgical management in epithelial ovarian cancer (EOC) has a significant impact in overall survival and progression-free survival. The Brazilian Society of Surgical Oncology (BSSO) supported a taskforce of experts to reach a consensus: experienced and specialised trained surgeons, in cancer centres, provide the best EOC surgery. Laparoscopic and/or radiological staging prognosticates the possibility of complete cytoreduction (CC0) and helps to reduce unnecessary laparotomies.

Diet influenced tooth erosion prevalence in children and adolescents: Results of a meta-analysis and meta-regression.

Objective: The aim of the present study was to assess the influence of diet in tooth erosion presence in children and adolescents by meta-analysis and meta-regression.

Data: Two reviewers independently performed the selection process and the quality of studies was assessed.

Sources: Studies published until May 2014 were identified in electronic databases: Pubmed, EBSHost, Scopus, Science direct, Web of Science and Scielo, using keywords.

Local and systemic tissue response submitted to injection of 2 and 30% polymethylmethacrylate in rats' tongue.

Introduction: Adverse effects on the oral mucosa after the use of dermal fillers have been reported due to their increased use for facial aesthetics.

Objective: This study aimed to evaluate, clinically and histologically, the local and systemic effects of two concentrations of polymethylmethacrylate (PMMA) dermal filler in rats.

Material And Methods: Fifty-four female rats were allocated into three treatment groups (2% PMMA, 30% PMMA and 0.

Endoscopic dacryocystorhinostomy.

Unlabelled: The endonasal surgical approach of the lacrymal sac assisted by video-endoscopy is carried out today with high success rates. Despite the satisfactory results reached with the traditional external approach, it has the disadvantage of requiring a skin incision and a consequent local scar. With the development and enhancement of the endonasal techniques, the endoscopic approach is increasingly preferred by surgeons.

Description of the technique of upper gastrointestinal series radiological examination for the evaluation of the esophagus, stomach and duodenum of Wistar female rats.

Purpose: To evaluate the anatomy of female Wistar rats and the workability of contrast radiography as a technique to investigate the gastrointestinal series.

Methods: Eight adult female Wistar rats were undergone to the contrast radiography as anteroposterior incidence and as posterior incidence in profile. The radiological examination was conducted at a 45 degrees angle to the radiological table.

Periodontal conditions of individuals with Sjögren's syndrome.

Background: Sjögren's syndrome (SjS) is a systemic autoimmune disease that might lead to hyposalivation and negatively affect the oral environment. The evidence with regard to the periodontal conditions in this group of subjects is still controversial. This study aimed to evaluate the periodontal clinical conditions and inflammatory markers in gingival crevicular fluid (GCF) from patients with primary Sjögren's syndrome (SjS [P]) or secondary Sjögren's syndrome (SjS [S]) compared to a control group.

Orthodontic space closure of lost traumatized anterior teeth - case report.

This case report refers to an 11-year-old boy with avulsion of the upper left central and lateral incisors. The teeth were replanted after 4 h, splinted with a semi-rigid splint for 12 days, and then endodontically treated. Severe progressive root resorption was seen after 2 years and the teeth were extracted.

Modified Glatzel mirror test reproducibility in the evaluation of nasal patency.

Unlabelled: The Glatzel Mirror (GM) is used to evaluate nasal patency. Validation studies are not available in the literature. This paper aims to verify the GM test reproducibility and the correlation between the intra-subject condensation area and nasal patency subjective perception.

Decreased Interleukin-1β and Elastase in the Gingival Crevicular Fluid of Individuals Undergoing Anti-Inflammatory Treatment for Rheumatoid Arthritis.

Background: The primary aim of this study was to compare the inflammatory activity in the gingival crevicular fluid (GCF) in a group of patients with rheumatoid arthritis (RA) and a group of matched controls. Secondarily, we aimed to evaluate the effect of rheumatologic treatment on periodontal inflammation.

Methods: Seventeen individuals with RA with a mean duration of disease of 12.

Effect of a 3% potassium oxalate topical application on dentinal hypersensitivity after subgingival scaling and root planing.

Background: The present study aimed to verify the effect of a single application of 3% potassium oxalate gel compared to a placebo gel immediately after subgingival scaling and root planing (SRP) on dentinal hypersensitivity (DH).

Methods: Fifteen patients undergoing periodontal treatment volunteered for this randomized controlled clinical trial. They presented with periodontitis on homologous contralateral canines and premolars, with complaints of dentinal hypersensitivity before periodontal therapy.
