This in vitro immunohistochemical study aimed to analyze the presence of factors of endothelial growth and cell differentiation in platelet-rich fibrin membranes. The presence of CD31 and CD163 markers indicated the potential for vascular neoformation and the significant presence of monocytes.

A cross-sectional study evaluating the salivary flow of 20 patients undergoing conventional radiotherapy in the head and neck region found that the mean total radiation dose (65 Gy) did not appear to influence the Xerostomia Inventory values or salivary volume. The data reinforced the subjective nature of xerostomia, which is not always related to hyposalivation.

This report of 2 cases describes the placement of fiber-reinforced fixed dental prostheses (FRFDPs) immediately after the surgical extraction of incisors. In each case, the extracted tooth was used as a pontic. The esthetic and functional results demonstrated that the FRFDP is a viable option to replace missing anterior teeth.

Pediatric Dentistry Antimicrobial activity of root canal filling pastes used in pediatric dentistryManuella de Oliveira FernandesFull Article (PDF)
Lucianne Cople Maia
Tatiana Kelly da Silva Fidalgo
An in vitro study evaluated the antimicrobial activity of root canal filling pastes commonly used in primary teeth: iodoform paste; zinc oxide + eugenol (ZOE) in a proportion of 1:3; ZOE in a proportion of 1:5; calcium hydroxide (Ca[OH]2) + water; iodoform paste + ZOE + Ca(OH)2; ZOE + Ca(OH)2; and chlorhexidine (positive control). Iodoform paste demonstrated the greatest activity against Enterococcus faecalis, while the specimens exposed to Ca(OH)2 + water demonstrated no activity.

Endodontics Efficacy of digital radiography for detecting a second mesiobuccal canal adjacent to unfilled or filled canalsLucas de Paula Lopes RosadoFull Article (PDF)

Erica dos Santos Carvalho
Matheus Lima Oliveira
Frederico Sampaio Neves
The accuracy of detection of the second mesiobuccal (MB2) canal when the adjacent canals were unfilled or filled with gutta percha was assessed using digital periapical radiographs. Intraobserver reproducibility ranged from substantial to almost perfect, and interobserver reproducibility ranged from fair to substantial. There were no statistically significant differences between groups in sensitivity, specificity, or accuracy. Detection of the MB2 canal can be challenging, and the presence of gutta percha does not influence the detection.

Mathias Pante Fontana
Gabriela Salatino Liedke
This study evaluated the use of smartphones for digitizing, sharing, and viewing radiographs in comparison to a conventional light box. Although the light box had better scores than the smartphones for sensitivity, specificity, and overall accuracy in detecting marginal gaps, the differences were not statistically significant.

Basic Science The effects of polishing techniques on surface roughness and gloss of different compositesGraziela Ribeiro BatistaFull Article (PDF)
Rayssa Ferreira Zanatta
Alessandra Bühler Borges
Carlos Rocha Gomes Torres
Evaluation of the effects of different polishing techniques on surface roughness and gloss of various composites revealed significant differences for both factors analyzed (composite and polishing technique). The polishing technique used is material dependent, but all systems tested displayed clinically acceptable results.

Endodontics The endocrown: a unique method for restoring endodontically treated teethAndy M. JanigaFull Article (PDF)
This report presents 3 cases of endocrown treatment as examples of common indications for this restorative approach: minimal tooth structure, questionable prognosis (rescue), and occlusal support.

Oral Medicine, Oral Diagnosis, Oral Pathology Detection of medial arterial calcification on CBCT images of a patient with undiagnosed type 2 diabetes mellitus: a case reportAdeyinka F. DayoFull Article (PDF)
Dale A. Miles
Beth R. Hamann
When medial arterial calcification is identified on cone beam computed tomographic images, the patient must be referred for evaluation of cardiovascular accident risk and the possible presence of type 2 diabetes. This report describes a case of undiagnosed type 2 diabetes confirmed by hemoglobin A1c levels after incidental detection of medial arterial calcification.

This study evaluated the influence of the screwdriver-screw connection geometry on the reverse torque of UCLA screws. Square, hexagonal, and hexalobular screws all had significantly different mean reverse torques. The hexalobular screws showed the greatest reduction from initial to final reverse torque, and the square screws showed the least.

A compressive strength test was used to assess the reduction in the fracture resistance of root dentin after exposure to an intracanal calcium hydroxide dressing for 7, 14, 30, or 90 days. The 14- and 90-day groups showed significantly reduced strength compared to the control group, but the 7- and 30-day groups did not.

Evaluation of the antibacterial effect of a green tea infusion used as a mouthwash revealed statistically significant differences between the intervention and control (distilled water) groups, with participants in the green tea group demonstrating greater reductions in colony-forming units in saliva and plaque biofilm.
