Anatomical configuration of the MB2 canal using high-resolution CBCT.

Objective: This study aims to evaluate the anatomical configuration of the mesiobuccal root of the maxillary first molar and assess the prevalence of the mesiobuccal canal (MB2).

Materials And Methods: A total of 307 high-resolution cone-beam computed tomography (CBCT) images of maxillary molars were analyzed. These images were classified based on the anatomical configuration and prevalence of the MB2 canal.

The influence of facial types on the morphology and location of the greater palatine foramen: a CBCT study.

Objective: This study aimed to assess the morphology and location of the great palatine foramen (GPF) of different facial types using cone beam computed tomography (CBCT) scans.

Methods: Sixty CBCT scans were divided into: brachyfacial (n = 20), dolichofacial (n = 20) and mesofacial (n = 20) using Ricketts' VERT index for the determination of cephalometric facial type and imported into ImageJ software. GPF shape was characterized as: round, elongated in the anteroposterior direction (EAP), or elongated in the latero-medial direction (ELM).

Evaluation of the Vertical Movement of Ribeiro's Dermolipoglandular Mammary Flap One Year After Mammaplasties in Post-Bariatric Patients.

Background: In 1971, Ribeiro isolated a segment in the inferior pole of the ptotic breast, nourished by muscular perforating vessels, and moved it cranially to the posterior region of the remaining detached breast tissue, where it was fixed to the pectoral fascia. This maneuver created a flap with autologous implant function, independent from the rest of the breast's support, that maintained long-term mammary projection.

Objectives: The objectives of this study were to measure the vertical movement of this flap 1 year after mammaplasty and to evaluate the factors involved.

Involvement of STI1 protein in the differentiation process of Trypanosoma cruzi.

The protozoan Trypanosoma cruzi is a parasite exposed to several environmental stressors inside its invertebrate and vertebrate hosts. Although stress conditions are involved in its differentiation processes, little information is available about the stress response proteins engaged in these activities. This work reports the first known association of the stress-inducible protein 1 (STI1) with the cellular differentiation process in a unicellular eukaryote.

Adaptation of gutta percha to oval canals: a cone beam computed tomographic analysis.

This study evaluated the influence of different instrumentation techniques on the adaptation of gutta percha cones in oval-shaped root canals. A total of 90 human single-rooted teeth were divided into groups according to the instrumentation technique that was used: group M, manual; group OM, hybrid: oscillatory plus manual; group PT, rotary (ProTaper Universal); group OPT, hybrid: oscillatory plus rotary (ProTaper Universal); group MT, rotary (Mtwo); and group OMT, hybrid: oscillatory plus rotary (Mtwo). After a single gutta percha cone was adapted to the canal, cone beam computed tomography was utilized to perform assessments at areas of greater contact of gutta percha to root canal walls.
