The mechanism of labor in nonhuman primates: A look inside

The Anatomical Record, EarlyView.
Abstract While in humans, the flexed position of the fetus and its rotating course down the birth canal are well documented, in other primates the mechanism of labor is unknown. Despite the lack of comparative data, it is commonly assumed that the human obstetric mechanism is unique, and anthropologists have disputed when and why the transition to the ...

Predictive Analysis of Maxillary Canine Impaction through Sella Turcica Bridging, Ponticulus Posticus Calcification, and Lateral Incisor Anomalies: A Retrospective Observational Study

Methods and Protocols, 2022
Maxillary canine impaction is an increasing dental anomaly and is often related to other dento-skeletal anomalies. The aim of this work is to support the clinician in evaluating the relationship between a displaced maxillary canine and clinical (the ...

Radiographic methods for locating impacted maxillary canines

Romanian Journal of Morphology and Embryology, 2023
Maxillary canine impaction is a fairly common phenomenon in dental practice. Most studies indicate its palatal position. For a successful orthodontic and∕or surgical therapy, it is necessary to correctly identify the impacted canine in the depth of the maxillary bone, using conventional and digital radiological investigations, each with their ...

The impacted maxillary canine: a proposed classification for surgical exposure

, 2012
Objective. One of the treatment options for the impacted maxillary canine is surgical exposure followed by orthodontic forced eruption. Several surgical techniques have been introduced in the literature for the exposure of the impacted canine. The aim of

Variable grouping patterns in primates: A test of the better competitor hypothesis in male Verreaux's sifaka (Propithecus verreauxi)

The Anatomical Record, EarlyView.
Abstract Intraspecific variation in social organization (IVSO) within primate populations can arise due to male mating competition. Verreaux's sifaka (Propithecus verreauxi) populations exhibit both single‐male and multi‐male groups, providing an opportunity to examine the relationship between male competitive ability and social organization.

Body mass and sex estimation from lower carnassial tooth morphometry in the endangered Iberian wolf (Canis lupus signatus): An ecomorphological analysis of sexual size dimorphism

The Anatomical Record, EarlyView.
Abstract The Iberian wolf (Canis lupus signatus) is an endangered subspecies characterized by highly fragmented populations and increasing human–carnivore conflict across the Iberian Peninsula. Although body mass strongly influences predator–prey dynamics and ecological performance, quantitative assessments of sexual size dimorphism (SSD) and body mass

Regional variability in skull sexual dimorphism: Olive baboons, blue monkeys, and vervets confirm the posterior region of the skull and the snout as opposite extremes of sex differences in Old World monkeys

The Anatomical Record, EarlyView.
Abstract This study, alongside prior work on crab‐eating macaques with O'Higgins, investigates regional variation in skull sexual dimorphism across different species of Old World monkeys. Findings reveal consistent patterns: the posterior skull regions (mandibular vertical ramus, chondrocranium and, possibly, the cranial vault) exhibit lower dimorphism,
