Unusual Case of Extraction of Maxillary Lateral Incisors and Mandibular Central Incisors [PDF]

Case Reports in Dentistry, 2017
Introduction. This article’s purpose is to report a case where maxillary lateral incisors and mandibular central incisors are extracted and a canine substitution was performed as the best therapeutic option in order to obtain symmetry in a malocclusion with an upper lateral incisor with poor prognostic, solve moderate crowding, get enough space for the

Establishment and evaluation of a novel rat model of the fourth ventricle hemorrhage

Animal Models and Experimental Medicine, EarlyView.
In this study, a novel rat model of fourth ventricle hemorrhage was established via autologous blood injection through the foramen of Magendie. Anesthetized rats were positioned in a stereotaxic apparatus with their heads tilted downward at an angle of approximately 20° relative to the vertical axis.

Could molar-incisor hypomineralization (MIH) existence be predictor of short stature?

International Journal of Preventive Medicine, 2020
Background: Molar--incisor hypomineralization (MIH) could be appeared in condition of calcium (Ca2+) disorders. Body height is an index of growth health monitoring in child that may be assumed by calcium metabolism. This study was designed to compare the

The prevalence of peg-shaped and missing lateral incisors with maxillary impacted canines [PDF]

Vojnosanitetski Pregled, 2019
Background/Aim. Many authors find that impacted maxillary canines is associated with missing and peg-shaped lateral incisor. The aim of this study was to examine the prevalence of peg-shaped and missing lateral incisor in subjects with impacted maxillary

Who was the real sabertooth predator: Thylacosmilus or Thylacoleo?

The Anatomical Record, EarlyView.
Abstract Sabertoothed mammalian predators, all now extinct, were almost exclusively feloid carnivorans (Eutheria, Placentalia): here a couple of extinct metatherian predators are considered in comparison with the placental sabertooths. Thylacosmilus (the “marsupial sabertooth”) and Thylacoleo (the “marsupial lion”) were both relatively large (puma ...

Management of avulsion-induced external root resorption of permanent maxillary left central and lateral incisors - a one-year follow-up case report

Trends in Pediatrics
The presented case elicits the successful management of external root resorption in an avulsed permanent central and lateral incisor due to failure to initiate root canal treatment (RCT) at the right time and prolonged splinting.

Morphological diversity of saber‐tooth upper canines and its functional implications

The Anatomical Record, EarlyView.
Abstract Elongated upper canine teeth, commonly known as saber‐teeth, have evolved three times within the sub‐order Feliformia. The species that wielded them flourished throughout the Cenozoic and have historically been separated into two morphological groups: the dirk‐tooths with longer, flatter canines, and the scimitar‐tooths with shorter, serrated ...

Growing sabers: Mandibular shape and biomechanical performance trajectories during the ontogeny of Smilodon fatalis

The Anatomical Record, EarlyView.
Abstract The evolution of organisms can be studied through the lens of developmental systems, as the timing of development of morphological features is an important aspect to consider when studying a phenotype. Such data can be challenging to obtain in fossil amniotes owing to the scarcity of their fossil record. However, the numerous remains of Rancho
