Essay On Bone Repair

In order to begin the study, a small area (0.5x0.5 cm) of calvarial bone was exposed, while the periosteum was left in tact (as it would be in normal conditions). The area was covered with 20 milligrams (mg) of Titanium particles and 5 mg of PE particles and then closed with sutures. Three days after the surgery, some of the animals were treated with an injection of PBS as a placebo, while some received a dose of 5 mg/kg OPG and some received 0.1 mg/kg of ZA. These dosages were chosen because they have been previously studied and determined to be the maximal safe pharmacological dose for a single injection. Some mice were also injected with a high dose of ZA (0.15 mg/kg) even though it is known to be toxic to humans, because in previous mouse studies it was shown to help prevent focal erosions. A separate group of mice received intermittent doses of Aln in a doseage of 10

The word laser is an acronym for, “Light Amplified by Stimulated Emissions of Radiation”, this means that all the lights in a laser have the same wavelength. Within a century of the laser being invented it occupied a major role in scientific research, medicine, industry, and even daily life. Lasers are used in the medicine field for procedures such as, laser eye surgery, heart, stomach, and intestinal surgeries. These procedures laser procedures are said to be harmless. Major factory industries use lasers to cut many things ranging from thin

The novel Salvage the Bones by Jesmyn Ward tell us a story about a 15-year-old African American girl named Esch. She lives with her father and 3 brothers in small bayou town called Bois Sauvage in Mississippi. Unfortunately, Esch is living an unhappy and poor family. Her father has problems with alcohol, and her mother died after her last pregnancy when Esch was only 8 years old. Even though Esch’s mother is dead, her presence is obvious from the very beginning of the story, and she stays present throughout the whole book. Esch constantly compares the present with the past, when her mother was alive. Mama is the only woman that Esch can refer to about feminine issues, among all

Over the years, advancements in healthcare have provided patients with an increased quality of life. Procedures such as kyphoplasty and vertebroplasty have provided such improvements with their introduction in healthcare only a few decades ago. There are several million people worldwide diagnosed with osteoporosis who suffer from vertebral compression fractures who now have the option to undergo one of these two minimally invasive procedures in order to experience immediate pain relief after conservative measures have failed.

Evidence from this study suggests only the short term effects of LASER. Further studies could include patients randomized by levels of baseline disability and duration of symptoms. Studies which states the long term effect of LLLT should be emphasized. Further, studies should evaluate many factors such as psychosocial aspect and dosiometry that may reflect on treatment response and recovery. The complete substitution of anti inflammatory drugs by LLLT, in patients that are at high risk, should also be targeted in future

her jaw. I explained to patient that an impacted wisdom tooth is a tooth that has failed to grow in the correct position that her tooth was lying sideways and pushing against the other teeth which was causing the pain along her jaw. When the

The goal of endodontic treatment is to promote the healing by prevention of apical periodontitis (AP) and to re-establish healthy periapical tissue 1. In spite of advances in endodontics, there are numerous factors contribute to endodontic treatment failure which includes residual necrotic pulp tissue, root canal over fillings, presence of periradicular lesions and periodontal disease. When root canal therapy fails, treatment options include orthograde re-treatment, periradicular surgery or extraction. Nonsurgical endodontic retreatment procedures are performed as the first choice to eliminate or reduce the microbial infection when the initial root canal therapy fails. The main goal of nonsurgical endodontic retreatment is to completely remove

In approximately 3.4% of the teeth that receive endodontic treatment, the pain is either initially

Though it was significantly used in the 1950s, it has decreased ever since. For instance, Melanoma is treated with Photocoagulation, where it helps in the side effects of radiation [1]. Other diseases such as Small and/or Medium Choroidal Melanoma are primarily treated with Photocoagulation [20]. Angiolytic lasers are used in Photocoagulation and have also been proven to be effective and safe for treatment [3]. From the beginning of this treatment, new techniques and skills have been added to better improve the function. Furthermore, it also helps to prevent retinal detachment and stop dystrophy from further developing; this makes diseases such as diabetic retinopathy and thrombosis (blood clot in the circulatory system) better to treat

This article details the use of lasers as a fat loss tool, which in this case worked on the patients better than usual exercise methods. The researchers provided background information on the use of lasers to treat injury and help with fat loss. They explained that using a laser and exerting a beam of 635nm to 680nm with a 10mW diode. This beam causes no temperature on the surface, it touches, but the adipose tissue under that area developed pores in the fat cells that leaked out the fat, which was picked up by lymphocytes and used in lipectomy and energy use throughout the body. These lasers have also been used to treat injury such as muscle tears and strains. The lasers would vascularize muscles and allow nutrients to enter to further speed up the recovery process.

There are various discomfort that a patient who undergoes an orthodontic treatment experiences. This discomfort may be due to the result of tension, functional restrictions or psychological dislike to wear the orthodontic appliance in the public. Common causes of orthodontic pain are the placement of the separators, alterations in the periodontal ligament and surrounding soft tissues, wire placement, appliance activation, Debonding of an orthodontic appliance. For the management of orthodontic pain, there are several ways such as analgesics, low-level therapy, vibratory forces, bite wafers, anesthetic gels, chewing gums, medicated wax, behavioral therapy.

The background of medicine has changed enormously from the past. These days, lasers are being used for many surgical procedures. Lasers can do a lot like; “vaporize tissue without touching it” (Gallagher 46). Back in the first century, medical instruments were made out of bones, rather than titanium or bronze, which doctors and surgeons commonly use today. Back then, citizens would

This study aimed to evaluate the effectiveness of a patient-applied 10% potassium nitrate glycerine-based gel in decreasing dentinal sensitivity on teeth with exposed dentin apical to the cementoenamel junction. The patients were divided into 3 treatment groups: group 1 was treated with a glycerine-based-10% potassium nitrate gel; group 2 was treated with a glycerine gel without potassium nitrate; and group 3 received no gel and no treatment (control). Following brushing and flossing, groups 1 and 2 applied the gel to the test teeth using custom-made soft acrylic trays, for a period of 5 min/ day for 4 weeks. Patient responses to cold water stimuli were measured at baseline (week 0), then at I-, 2-, 3- and 4-week intervals. Group 1 patients showed a significant decrease in sensitivity to cold at week 2 only. The group 2 patients showed a significant decrease in sensitivity to cold after 3 and 4 weeks. A statistically significant decrease in sensitivity was noted between group 2 and group 3 patients at week 3, the most sustained decrease in sensitivity to cold was found on teeth treated with plain glycerine.

The conventional Argon laser treatment is associated with heat to the surrounding tissues such as the neurosensory retina and the choroid leading to collateral thermal damage. The greyish endpoint of a laser burn means that the temperature is high enough to change the transparency of the retina [8].

The laser is used to vaporize a layer of epithelium, and this skin is cleared from the field with a moistened cotton tip applicator or gauze. Johnson et al. described the depth of treatment for CO2 laser therapy, as several histologic layers can be differentiated with consecutive laser passes, such that the full depth of dysplastic involvement can be removed. Thus, use of the laser is theoretically curative for AC and does not cause deep dermal damage with ensuing scar formation.
