Bjöern Ludwig, Bettina Glasl, in Temporary Anchorage Devices in Orthodontics (Second Edition), 2020. The Canine Torque. The anatomic difference of the root morphology between the lateral incisor and the canine often requires a palatal root torque of the mesialized canine—this can be applied, for example, via a suitable bracket, and, if necessary, can be additionally amplified by third order ...

Which Morphological Characteristics Are Most Influenced by ...

Nov 15, 2012  Morphology of downy mildews thus seems to be dependent on several different factors, some of which have not been characterized to date. Most of the comparative studies of closely related downy mildews underpin their molecular phylogenetic results with morphological differences of the pathogens, even if there are only very few diagnostic SNPs.

Dental Anatomical Features and Caries: A Relationship to ...

Dental caries is a multifactor disease affecting a significant number of people throughout the world. However, in recent decades the widespread availability of fluoride and other preventive measures have resulted in a decline in the prevalence of caries among children and young adults. Currently, it is accepted that most carious dental lesions are restricted to specific anatomical sites.

Jan 30, 2014  The appositional articular morphology of the talo‐crural joint is the third component of the joint complex. It is a site of internal integration of this highly stable functional evolutionary unit. Prior studies of the other two components, tibia and talus, demonstrated that substrate preference influenced their articular shape.

Morphology is a critical element of successful vocabulary development and accurate decoding. Awareness of morphology has been shown to be a strong indicator of and positive influence upon reading comprehension (Soifer, 2005). Subsequently, weakness in decoding and vocabulary skills is noted as a potent inhibitor to fully comprehending text.

Root - Wikipedia

Root morphology is divided into four zones: the root cap, the apical meristem, the elongation zone, and the hair. The root cap of new roots helps the root penetrate the soil. These root caps are sloughed off as the root goes deeper creating a slimy surface that provides lubricant.
