Mandible

was injured in November 2007 in Kandahar, Afghanistan. I was commanding the vanguard of a combat team leaving a patrol base to conduct a night operation in the Zharay district. Shortly after our departure and ‘shake-out’ into formation, my command vehicle was hit by a Command-Wired IED that defeated the armour and safety systems aboard our Light Armoured Vehicles. The initial blast and subsequent fire that spread to the ammunition and explosives we were carrying generated three Killed-in-Action…

exploration of teeth when looking at replacement of a missing tooth or healing a tooth from carious bacteria. The average human body has 20 deciduous teeth and 32 permanent teeth. Deciduous teeth are fully formed at birth located within the maxilla and mandible and start to erupt at 4 months of age. The deciduous teeth are a guide for eruption of the permanent teeth. Permanent teeth erupt into the roots of the deciduous teeth causing root resorption to occur. Once the root of a deciduous…

9. For the next step, we will be taking the measurements for the prognathism of the of the skull. In order to so lay the skull on its side so it’s parallel to the table. 10. Using the protractor point the socket where the mandible meets the cranium. The smaller the angle the higher the likelihood of prognathism. 11. Record the measurements once more in your data table and continue doing so with the remainder of the skulls 12. For…

strolled off to the other side of the compound.

It was hot.

Barry took a step towards his tent, and caught a movement out of the corner of his eye. A wind scorpion had decided to use his shadow to get out of the sun. Big one too. It’s body, head and mandibles were at least the size of his palm.

Jeez, they were creepy looking things, and not really scorpions from what he understood, but closely related. Barry realized that he was going to have to make the decision to either run for his tent,…

Alveolar Ridge Resorption: Alveolar bone resorption is a normal physiologic response following teeth extraction. The causes of alveolar bone volume loss can occur before dental extraction due to periodontal disease, periapical pathology and trauma to the teeth and bone. (SchroppL et al.2003) (1, 2). Additionally, the traumatic removal of teeth can cause bone loss and must be prevented (1,3). Finally, the alveolar bone suffers atrophy after tooth extraction, which has been well documented (1, 4,…

is passing through the larynx and the laryngeal membranes, the vocal folds are abducted resulting in medial compression at the midline so air cannot escape. The thyoarytenoid makes up the majority of the vocal folds. The stylohyoid contraction at mandible will draw the hyoid up and down. With the tongue, positioning is helped by the hyoglossus in the phonotory system. Phonation is initiated as air pressure below the glottis overcomes medial compression, now the vocal folds are…

Results In the univariate analysis factors race and side proved to be insignificant by the Wald test at 5% significance level. Hence the eruption sequence does not significantly differ among the Races and remains unchanged between left and right side in the mouth. Then a multivariate CoxPH model was fitted using variables District, SS, gender, jaw and type which were the significant variables in the univariate analysis. These five variables continued to be significant in the fitted multivariable…

stems from an unproven theory from the 1964 study by Stenger that stated, “The properly fitted mouthguard effectively increases the time and distance involved in acceleration when the mechanism of injury is an upward blow to the head through the mandible.” It also discusses what factors besides the blow can contribute to a person suffering from a concussion such as genetics, force of blow, mass of player etc. Although this article goes into an in depth discussion of how the thickness of…

By looking at the fetal pig and its muscle structure, researchers and individuals are able to gain a better understanding of what human muscles look like, where they are located, and how they function. The muscles that were labeled in the dissection are important factors in the movement of the individual. The muscles work together though antagonism. Antagonism works when one muscle, such as the extensor carpi radialis contracts, and the flexor carpi radialis relaxes, allowing the hand to extend.…

shifted her airway making it difficult to breath. She came back to the hospital where they opened and stabled her airway with an emergency trach. She had a CT scan which showed an abscess, evidence of an infection and cellulites present along her mandible and sublingual space. For treatment a penrose drain was placed in her neck and ordered to be irrigated twice a day to clear out the drainage. She was given an NG tube and put on antibiotics and pain medication. On Tuesday the majority of my…
