By allowing stem cell research to continue, whether federally monitored or not, we are experiencing major science breakthroughs. Current scientific discoveries include creating a bladder from cloned cells and the regrowth of a mandible. (Stocum, 2014) Whether you are supportive of scientific research utilizing embryonic stem cells or supportive of the science that is aided by pluripotent stem cells, it is hard to deny there is a bonus to both and the research should be allowed…

Patient Y is a 58year old male that was referred to our department with a large (3x3cm) node of the R neck, level II, which he had had for 3 years. His fine needle aspiration (FNA) results showed potential small cell neuro-endocrine tumour, but had insufficient tissue for a confirmed diagnosis. His oncologist sent him for further staging tests, which included a MRI which only confirmed the nodal involvement and advised a core needle biopsy of the mass. This revealed a squamous cell carcinoma…

As a new parent, one of the biggest decisions to make involving their newborn child is whether the baby will be feed through breast or bottle. Some might say that breast is best. But there are other individuals who have reasons to why he/she may lean more towards bottle-feeding. There are benefits and conflicts on both breastfeeding and bottle-feeding. But parents depend more on the feeding method that is more convenient and healthier for their newborn infant. The amount of times a baby eats…

backed up with ample data and new tests showed that homo floresiensis were not homo sapiens with LS. “LB1 and patients with LS differ markedly in the size and shape of the cranium; thickness and pneumatization of cranial bones; morphology of the face, mandible, teeth, and chin; form of the shoulder, wrist, and pelvis; and general body proportions including relative foot size.”(2) Other scientists have done research looking for comparisons between the skeletal structure of the homo floreisienis…

They use quarter to half inch circular pieces of leaves which they cut with their mandibles (Serrano). The bees use the cut leaves to line their nest. Each nest consists of repeating segments or cells of nesting material, larvae, and pollen. The pollen provides food for the bee until it emerges from the nest. Each cell will produce one…

Osteolysis, also known as “disappearing bone disease,” is a condition where parts of your skeleton begin to disappear and is usually a side effect of another underlying cause taking place in your body. Osteolysis tends to be idiopathic which means it came about spontaneously and the cause is undiscovered. The first case of Osteolysis was reported in 1838 in which an 18 year old man’s humerus disappeared completely. It disappeared over a course of 11 years, in which he suffered two fractures to…

Discussion: A linear discriminant function is a set of measurements that is weighed against other measurements to gain the most accurate estimation of all the measurements combined within a particular taxon of skeletal remains. The weighing of each set of measurements is to provide the smallest amount of error in determination of sex, ancestry and stature of a particular individual. By applying the tested methods of discriminant function analysis to the specimen of UC71 and UC20/UC53-Cranium,…

The first mouth-guards were created in 1890 by a London dentist, Woolf Krause, to shield boxers from lacerations of the mouth (McCrory, 2001). Sport mouth-guards surfaced in the United States in 1916 when they were produced by a Chicago dentist, Thomas Carlos (Reed, 1994). Sport mouth-guards were primarily used for boxers during the early 1920s and 1930s to prevent a range of dental injuries, most notably cracked teeth. Known by their nickname of “gum shield”, mouth-guards were originally…

Introduction: Maxillary canines impaction is a common condition , and dentists must be ready to manage the situation. Early detection of impaction with time interception, and well-managed orthodontic and surgical treatment, impacted maxillary canines can be guided to erupt in an appropriate location in the dental arch.(1) Maxillary permanent canines position is very strategically important in keeping the occlusal relationship symmetrical and harmony. The upper canine are the most impacted…

inter-cuspal position”.(1) The OVD is determined by the repetitive contracted length of the elevator muscles which sets the jaw-to-jaw relationship.(2) During growth and development OVD affected by three factors: Growth of the ramus, gonial angle of the mandible and Eruption of the teeth.(3) Patients with short ramus and obtuse gonial angle have an increased facial height and excessive tooth and gingival display.(4)(5)(6) Patient with long ramus and acute gonial angle have a short lower face,…
