A CASE OF LOWER ANTERIOR PRIMARY TEETH FUSION

Journal of Dentistry Indonesia, 2006
Dental fusion is the most common problem seen in the primary dentition. The incidence of dental fusion was approximately 0.5% for deciduous dentition and 0.1% for permanent dentition. Fusion may be complete or incomplete.

New craniodental materials of Falcarius utahensis (Theropoda: Therizinosauria) reveal patterns of intraspecific variation and cranial evolution in early coelurosaurians

The Anatomical Record, EarlyView.
Abstract Despite documented ecomorphological shifts toward an herbivorous diet in several coelurosaurian lineages, the evolutionary tempo and mode of these changes remain poorly understood, hampered by sparse cranial materials for early representatives of major clades. This is particularly true for Therizinosauria, with representative crania best known

New techniques for old bones: Morphometric and diffeomorphometric analysis of the bony labyrinth of the Reilingen and Ehringsdorf Neandertals

The Anatomical Record, EarlyView.
Abstract Neandertals are known to possess very distinctive traits in their bony labyrinth morphology, such as an inferiorly positioned posterior canal and a very low number of turns in the cochlea. Hence, the inner ear has been often used to assess the Neandertal status of fragmentary fossils.

An ontological morphological phylogenetic framework for living and extinct ray‐finned fishes (Actinopterygii)

The Anatomical Record, EarlyView.
Abstract The ray‐finned fishes include one out of every two species of living vertebrates on Earth and have an abundant fossil record stretching 380 million years into the past. The division of systematic knowledge of ray‐finned fishes between paleontologists working on extinct animals and neontologists studying extant species has obscured the ...

Does salinity make a difference—Kidney anatomy of Saimaa (Pusa saimensis) and Baltic ringed seals (Pusa hispida botnica)

The Anatomical Record, EarlyView.
Abstract As habitat salinity markedly differs between the endangered, freshwater‐dwelling Saimaa ringed seal (Pusa saimensis Nordquist, 1899) and the brackish water‐inhabiting Baltic ringed seal (Pusa hispida botnica Gmelin, 1788), we investigated whether this difference has resulted in morphological changes to their kidneys.

The skeleton of the green Iguana iguana (Squamata: Iguanidae) and its intraspecific morphological variation

The Anatomical Record, EarlyView.
Abstract The green iguana (Iguana iguana) is an iguanine lizard with herbivorous and arboreal habits, whose distribution spans through South America, Central America to the south of North America. Although the genus Iguana is well‐known, the species still lacks a comprehensive and up‐to‐date anatomical study, particularly addressing the axial skeleton,

Mixed Dentition Caries – Predictor Of Carious Activity In Permanent Dentition

Romanian Journal of Oral Rehabilitation, 2013
Aim of the study is the optimisation of the child’s dental management, especially regarding the health and odonto-periodontal integrity of mixed dentition. Materials and methods We performed a clinical and paraclinical population based study from the point of view of carious activity in mixed dentition on a lot of 212 subjects with the ages between 6 ...

Cranial anatomy of a Late Cretaceous aspidorhynchid fish (Neopterygii: Aspidorhynchiformes) from Alberta, Canada

The Anatomical Record, EarlyView.
Abstract Belonostomus longirostrisis was named for an isolated jaw fragment from freshwater Upper Cretaceous (Campanian) sediments of the Dinosaur Park Formation of Alberta, Canada. Following the description of the Albertan species, numerous isolated cranial and postcranial elements have been collected from the Dinosaur Park Formation and assigned to B.
