Wheat grain yield consists of three components: spikes per plant, grains per spike (i.e. head or ear), and grain weight; and the grains per spike can be dissected into two subcomponents: spikelets per spike and grains per spikelet. An increase in any of these components will directly contribute to grain yield. Wheat morphology biology tells that a wheat plant has no lateral meristem that forms ...

A supernumerary tooth is a tooth that is additional to the normal set of teeth and are most commonly seen in the anterior maxillary region [1]. Supernumerary teeth are more common in permanent dentition as compared to primary dentition. The prevalence is 0.15–1% in permanent dentition and 0.3–0.6% in the primary dentition with proportion of 2:1 for male sex [2]. The presence of a supernumerary ...

OBJECTIVE The objective of this study was to estimate the incidence of non-syndromic supernumerary premolars, to classify them and to identify the complications related to them. STUDY DESIGN This retrospective cohort study was composed of 8400 panoramic radiographs of patients who presented at our Oral and Maxillofacial Surgery Services from January 1998 to May 2008. The number of supernumera...
