Saliva is a watery liquid that is produced by the salivary glands (Martini et al., 2015). There are three pairs of salivary gland; the parotid, sublingual and submandibular. Each of these glands have different cellular structure and produces saliva with slightly different content that preforms different functions (Martini et al., 2015). The parotid salivary glands which is the largest produce a serous excretion that contains high amounts of salivary amylase which helps in the breakdown of complex carbohydrates. The sublingual salivary glands produces mucous excretion that functions as a lubricant and buffer (Martini et al., 2015). The submandibular salivary glands produces mucin which is a combination of buffers and glycoproteins, salivary amylase is also released. Each gland releases their products through their respective ducts into the buccal cavity or mouth. Saliva itself consist 99.4% of water and the 0.6% left are buffers, electrolytes, mucins, enzymes and antibodies (Martini et al., 2015). Sugar, Na+ and Cl- are in low concentration and this is to prevent interference with the sense of taste (Calhoun & Eibling, 2006). Saliva has thus multiple functions. When secreted saliva forms a film over the structures of the mouth (Calhoun & Eibling, 2006). The saliva that makes contact and moisten food that is ingested does …show more content…
One the saliva washes away any food source for these bacteria and some of these bacteria themselves and is then swallowed and digested. Two lactoferrin that is produced binds any iron present in the mouth prevent any bacteria from using iron in their multiplication process (Sherwood et al., 2013). Three an enzyme lysozyme breaks down the cell walls of some bacteria thus causing the bacteria to undergo lysis. Four a glycoprotein named salivary agglutin forms a complex with IgA (antibody) which then proceeds to bind to bacteria present (Sherwood et al.,
Crunch, Crunch, Crunch. As you munch on those first few Cheetos the digestion process begins in your mouth. Here, mechanical digestion begins to reduce the size of the Cheeto and mixes the food particles with saliva. The tongue helps mix and move the pieces of Cheeto throughout the mouth. The salivary glands in the mouth also contribute to the breakdown of the Cheetos in the mouth. They secrete amylase and mucus. The parotid glands begin chemical digestion on the Cheetos. It secretes a clear, watery fluid that is high in amylase. The enzyme, amylase, begins to breakdown carbohydrates into disaccharides. The other two salivary glands, the submandibular and the sublingual, secrete saliva containing mucus, which binds and lubricates the Cheeto particles for easy swallowing. Now the food has been formed into a bolus with the help of saliva, the tongue, and teeth. Next the bolus travels into the pharynx, where the epiglottis closes off the top of the trachea so no food can enter. Then it moves on to the esophagus, where peristaltic waves push the food toward the stomach. The food enters the stomach through the cardiac sphincter at the end of the esophagus.
o Please describe a time when you performed a thorough head, neck and oral exam and the findings had a significant impact on how you proceeded with the dental hygiene process of care. Annette was performing her usual head, neck, and oral exam on a patient and found an enlarged thyroid. She recommended to the patient that she go see her primary care physician to get a better diagnosis. The patient went to her primary care physician and was told there was probably nothing. Later, the patient returned to the dental office and saw Annette and told her what the physician said.
Can spit acid some distance, much like a spitting cobra, and uses it to blind and immobilize victims but it is very inaccurate and takes several moments to recharge. However it can spit the normal saliva as any time, and is much more accurate with it. There is no recharge time needed for regular spit. Which is helpful if using it for healing purposes. Almost always salivating a sticky, clear slime that can be used to soothe burns from Xenomorph's body fluids because it is made of a base, which neutralizes
The Skin of Our Teeth by Thornton Wilder illustrates a family dodging one catastrophe after another. By the skin of their teeth, they will defeat ice, flood, and war. The main characters of this play are George and Maggie Antrobus, their two children, Henry and Gladys, and Sabina, who appears as the family's maid in the first and third acts, as well as a beauty queen seductress in the second act. The Skin of Our Teeth takes place at the Antrobus home in Excelsior, New Jersey; and the Atlantic City boardwalk.
Streptococcus mutans is a gram positive cocci shaped bacteria. It is a facultative anaerobes. Streptococcus mutans is found in the oral cavity and now can be found in the heart tissue and valves. Considering the fact that Streptococcus mutans is a facultative anaerobe the bacteria is often found in between your teeth, around your gum line, and on your occlusal surfaces. Streptococcus mutans lives in temperatures that range from eighteen to forty degrees celsius falling into the mesophile category. Streptococcus mutans changes the environment by adhering to a bio-film layer produced on the enamel surface of your teeth from such things including: acidic foods that contain sugars and starch, drinks that contain carbonation and sugars, whiting products, tobacco use, and lack of oral home care. The first virulence factor is dependent on the synthesis of water-soluble glycans from the disaccharide sucrose. By breaking down the glycogen this allows help for bacteria adhere better. Next virulence factor, Streptococcus mutans has the ability to become more acid tolerant and cell to cell communication. Once the bacteria is colonized in the bio-film it starts to produce an acidic environment below a ph of 7.(Kreth, et al., 2008) By doing so, Streptococcus mutans out competes any other organism living on the teeth or in the oral cavity. This leads to the third factor, which displays a production of lactic acid fro...
Saliva contains glucose; therefore, if you have uncontrolled diabetes, the amount of glucose present in your saliva is elevated. We naturally have somewhere between 200 to 300 bacterial species in our mouths: Some of these bacteria are good and some of them are bad. Streptococcus mutans is typically the bacterium responsible for causing tooth decay; whereas, periodontal disease is usually caused by a mixture of Porphyromonas gingivalis and Treponema denticola.
Salivary gland cysts or sialoceles can occur without any identifiable cause but usually are a complication of surgical or physical trauma to the major salivary glands (parotid, submandibular, or sublingual glands). These glandular structures are associated with a network of ductal systems that allow saliva to flow from the glands to the oral cavity. When trauma disrupts the continuity of this association between gland and duct, saliva can no longer flow into the oral cavity. This can lead to accumulation of saliva in the surrounding tissues or the gland itself, otherwise known as a sialocele. A sialocele can caused by physical trauma to glandular structures (e.g. accident, facial trauma), surgical trauma to glandular structures (e.g. after
The child is at stage three linguistic speech in oral development (Fellows & Oakley, 2014). They show evidence of this in both their receptive and expressive language meeting the criteria for this stage (Fellows & Oakley, 2014). They show evidence of their receptive language by their ability in being able to understand opposites (Fellows & Oakley, 2014). While they had some issues with the differences between soft and scratchy they were able to demonstrate the differences between big and little several times during the dialogue. They showed evidence of their expressive language by their use of telegraphic speech, expanding vocabulary and in the ability to take in turns of speaking and listening (Fellows & Oakley, 2014). Telegraphic
Dentinal hypersensitivity is characterized by a short, sharp pain in response to stimuli. Dentinal hypersensitivity, which is more commonly seen in adults in the 20 – 40 – year old age group, has several etiological factors. Gingival recession and enamel loss both contribute to the prevalence of this condition, resulting in the exposure of dentin.
-Characterized by the elongation and hyperkeratosis of the filiform papillae, resulting in this hairlike appearance. The elongated papillae usually exhibit brown, yellow, or black pigmentation. Most patients are asymptomatic, but occasionally patients complain of irritation, gagging, or an altered taste. Patients are usually heavy smokers with poor oral hygiene and some have vitamin deficiencies, GI problems, or radiation therapy. Cures range from just brushing the tongue to corticosteroid therapy.
there are about 70-118 groves along the throat which help with sending out water from the
Dental plaque is the combination of bacteria embedded in a matrix of salivary proteins and bacterial products superimposed on the acquired pellicle (Berkovitz, et al., 2011). It is an example of a biofilm, a term used to describe relatively undefinable microbial community associated with a tooth surface or any other hard, non-shedding material (Reddy, 2008). Plaque can also be described as

Dental hygiene is a dynamic and challenging career that offers team work, personal growth, and extraordinary benefits, and it is the perfect career for me. As a health care professional, the dental hygienist is an important member of the dental team providing patient care. Good qualities for a dental hygienist are compassion and enjoying talking to people which are two qualities that fit my personality. I love the thought of knowing I made a positive impact in a person's health. Becoming a dental hygienist professionally requires you to obtain an associate degree in dental hygiene. They affect the average American by educating them about dental care. A dentist helps people with their dental health, which can greatly impact a person’s day-to-day life.
So there is a soft sticky substance that doesn’t have color and forms in your mouth all the time. That stuff is called plaque! It’s not just on your teeth, it sticks to your tongue too! So plaque starts out when the saliva sticks to the teeth called acquired pellicle and two types of tiny bugs called bacteria, Lactobacillus and Streptococus stick to it. We’ll call them LB and SC, and they like to live in big groups called colonies inside the plaque which has the food that you eat, which they like eating too! Mixed with your saliva, the food you eat breaks down into sugars, and they eat it and produce waste that sits inside the plaque. Eww, right? But its easy to clean the plaque off if you brush and floss properly! But if you don’t it will harden, and become Calculus also called tartar, and that stuff is yellow, sometimes brown or black. It looks really gross. So make sure to brush your teeth and floss so it won’t get hard and nasty.
