The prevalence of enamel hypoplasia on permanent teeth among children aged 9-12 years based on the type and teeth affected

Padjadjaran Journal of Dentistry, 2010
Introduction: Enamel hypoplasia is defect which is an abnormality on the enamel structure. The abnormality causes an aesthetic problems that affects the psycologic of a child, and also makes it easier to form a caries. The purpose of this research was to

Pit and fissure sealants versus fluoride varnishes for preventing dental decay in the permanent teeth of children and adolescents.

Cochrane Database of Systematic Reviews, 2016
BACKGROUND Most of the detected increment in dental caries among children and adolescents is confined to occlusal surfaces of posterior permanent molars. Dental sealants and fluoride varnishes are much used preventive options for caries.

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
