Case Study of Eruption Cysts
Case Study of Eruption Cysts Eruption cyst not uncommon: A series of three cases Abstract Aim: Presentation of three clinical cases with an eruption cyst Background:à Eruption cysts are rarely seen benign cysts most commonly encountered on the mucosa before the tooth eruption Case description: In two patients, eruption cyst occurred in the maxillary arch and in one patient it foundin the lower arch. The three eruption cysts were found with the permanent teeth. Surgical treatment was done in all three cases and tooth erupted in normal pattern Conclusion: Eruption cyst requires surgical interventionwhen patient experiences any hurt, bleeding or when they get infected and face unesthetic appearance. Surgical excision requires to relive the child from discomfort. Clinical significance: Knowledge about occurrence of eruption cyst, a rare developmental eruption disturbance is very essential to provide the correct diagnosis and treatment Key words: Benign cyst, eruption cyst, surgical excision INTRODUCTION eruption cysts are rarely encountered benign soft tissue lesions seen on the mucosa before the tooth eruption takes place. Some authors belived them as either dentigerous cysts or follicular cysts. However, they are categorized as separate lesions as they seen only in soft tissue. The pathogenesis behind the development of this cyst is not known. One author has found trauma, infection and deficient space for eruption as main etiological factors for their occurrence based on the retrospective study of their 36 cases. It appears to be to arise from the separation of the epithelium ffrom the enamel of the crown of the tooth due to an accumulation of fluid or blood in a dilated follicular space. The exact etiology of occurrence of eruption cyst is not clear. Aguilo et al.3 in their retrospective clinical study of 36 cases, found early trauma, infection and theà deficient space for eruption as possible causative factors. It seems to be toarise from the separation of the epithelium from the enamel of the crown of the tooth due to an accumulation of fluidà or blood in a dilated follicular space literature search shows low prevalence of these cysts. The reason behind low prevalence could be attributed to the fact of being them considered as dentigerous cysts by many investigatorsà in addition to this only few reports show the definitive diagnosis of these cysts using biopsy since they are benign lesions This may also suggest that either the eruption cyst is an unusual lesion or it is an accepted local disturbance that is associated with the eruption of many teeth. The clinicalsignificanceof low prevalence may also be due to the factthatmost often the dentist sees only symptomatic eruption cysts and the majorityresolves unnoticed CASES DISCRIPTION We hereby report three cases of eruption cyst who reported to the Out Patient Department ofà Pedodontics and preventive dentistry, College of Dental sciences, Davangere, Indiaà Case No A12-year-oldà male child along with his parents reported with theà chief complaint of bluish black swelling on the gums in the front region of the upper jaw [Figure1a]. History of the case revealed lesion started appearing weeks back as translucent swelling over normal mucosa and it increased to its present size.à The color of theà lesion also slowly changed from its normal red mucosa to the present bluish black colorone week back No fluidà discharge or any other associated symptoms were associated. The general physical examination of the child showed no abnormalitiesExamination of the oral cavity revealed that the child was in the mixed dentition stage.à Soft tissue examination did not show any abnormalities except, the presence ofswelling on the buccal gingiva with respect to unerupte d 11, not extending to palatal surface. Clinically the lesion as bluish-black, circumscribed, fluctuant swelling that measured approximately 1 x 1.5 cm in diameter and was very soft inconsistency. The mucosa was smooth and no ulcerationor bleeding was present Case No An 8-year-old female patient reported with the chief complaint of non erupting upper front tooth alongà with a swelling in upper anterior region Figureà 1b]. Lesion started appearing 6weeks back as translucent swelling over normal mucosa and it slowly increased toà reach present size. It associated with dull aching pain on mastication.à The general physical examination of the child showed no abnormalities.à Examination of the oral cavityà showedthat the child was in the mixed dentition stage. All the permanent 1st molars had completely erupted and allcentral incisors except were erupted. Swelling measured approximately 1x 1 cm in diameter and was very soft and fluctuant and slightly bluish in color. The was smooth with no ulceration or bleeding Case No A 7- year-old boy reported with the chief complaint of swelling inlower left back tooth region [Figure 2a]. Lesion started appearing 3 weeks back translucent swelling in the region of unerupted left permanent first molarand it slowly increased to its present size.à Examination of the oral cavity revealed that the child was in the mixed dentition stage. All the permanent 1st molars had completely eruptedà except mandibular left molar Swelling measured approximately 2 x 2.5 cm in diameter and was very soft and fluctuant with bluish color. In this case too, the overlying smooth with no ulceration present Radiographic examination Case 1 showed presence of 11, case 2 showed presenceof 21, case 3 showed presence of 36 in the stage of eruption and involvement or any radiolucency surrounding this tooth.Based on clinical and radiographic examination, the lesions were diagnosed as eruption cyst associated with 11, Treatment The clinical condit ion was explained to the parents and they were advised to observe the swellings for another 2 weeks as it may rupture on its and may notrequire any surgical intervention. Patients reported after 15-20 days. In all three cases, the swelling was not resolved and complained of discomfort associated with swelling while chewing food. The surgical procedure was explained to the parents and consent was obtained for the same. A blood investigation was carried out before the procedure.In first two patients,the treatment included incising the eruption cyst with BP bladeno.15 and draining the contents of the cyst. A window was cut leading to the exposureof 11 and 21. In third patient as little big with thick mucosa overlying, the superficial part present over 36 was excised completely and it was sent for histological examination. content of the cyst was drained completely. Post operative instructions were given in all patients [Figure 1c, 1d and 2b]. The case 1 and case reviewed after one month and a normal eruption pattern was observed [Figure 1e, 1f]. In addition of surgical excision of cyst in case 3, pulp for 74, cementation of modified distal shoe with intra-mucosal extension was cemented to guide the eruption of 36 [Figure 2c] and reverse crown and loop space maintainer cementation was done to prevent the mesial migration of 46. Case reviewed after 2 and 4 weeks and a of 36 was observed [Figure 2d and 3a]. After 3 month, when complete eruption of 36 was observed, distal shoe appliance was replaced and loop space maintainer [Figure 3b Microscopic examination: Haematoxylin and Eosin stained section from case No. 3 revealed, stratified squamous parakeratinized epithelium with areas of acanthosis. Connective tissue was moderately fibrous with areas of extravasated RBCs, few blood vessels and chronic inflammatory cell infiltrate of plasma cells and lymphocytes. Few inactive odontogenic rests was also seen in the connective tissue DISCUSSION on clinical examination eruption cysts appears as aelevated dome shaped swelling more commonly encountered on the mucosa of the alveolar ridge.

On palpation these lesions feel soft in consistency and the surface colour usually appears as bluish, purple to black or transparent color. Ità raised Clinically, eruption cyst appears as a dome shaped raised swelling in the mucosa of the alveolar ridge, which is soft to touch and the color ranges from transparent, bluish, purple to blue-black.2 Inall three presented cases here, theà color of the cyst ranged from reddish black to bluishà Eruption cyst found to appear more in the upper arch compared to lower and commonly involving anterior teeth.to be more prevalent in the maxillary archinvolving anterior teeth. Eruption cyst associated with molars and premolars is very rare. Nagaveni et al.,5 reported development of this cyst in relation to mandibular first premolar which is a rare finding on radiographic examination it is difficult to differeciate between the cystic space of eruption cyst. The reason could be the presence of both the cyst and tooth in the soft tissue. In case of dentigerous cyst we can appreciate anunilocular radiolucent region in the shape of a half moon on the crown of a non-erupted tooth. 2on h istological examination the eruption cysts shows the similar microscopic features of the dentigerous cysts which consists of connective fibrous tissue covered by a fine layer of non-keratinized cellular epithelium.à à area It is difficult to distinguish the cystic space of eruption cyston radiographbecause both the cyst and tooth are directly in the soft tissueà in contrast to dentigerous cyst in which a well-definedà unilocular radiolucentarea is observed in the form of a half moon on the crown of a non-erupted tooth.2Histologically,the eruptioncyst presents the same microscopic characteristics as the dentigerous cyst, with connective?brous tissue covered with a fine layer of non-keratinized cellular epithelium.2 On histologic examination of tissue excised from case no. 3 showed stratified squamous parakeratinized epithelium with focal areas of acanthosis, chronic inflammatory cells and few inactive odontogenic rests in connective tissueà most of the times, the eruption c ysts do not need any treatment and they resolve on their own. 4,7 surgical treatment is required when they show bleeding, infected, hurts the patients or esthetically unpleasing. 2,8 Treatment is done to give relief from the discomfort resulting from the eruption cysts. The treatment involves simple excision or excision of the overlying tissue to expose the crown and draining the fluid is carried out in cases where the underlying tooth is not erupting or when the cyst is increasing in size. Mostly, the eruption cysts do not require treatment and majority of them disappear on their own.4,7 Surgical intervention is required when they hurt bleed, are infected, or esthetic problems arise.2,8 Treatment has to be performed in order for the childto be relived from discomfort arising lesion.Simple incision or partial excision of the overlying tissue to expose the crown anddraining the fluidis indicated when the underlying tooth is not erupting or the cyst is enlarging advanced imaging techniques like the diode laser system is an excellent equipment for the management of eruption cyst. The advantages include elimination for the need of local anesthesia in majority cases.9 As a result the occurrence of possible complications, toxicity and allergic reactions are avoided. This diode laser has bactericidalcoagulative effects. In addition to this one can appreciate mild bleeding and better visualization of the working area as compared to conventional scalpel method of treating erupti on cysts. 10 In thepresented 3 cases, we used scalpel for incising or excising the lesion as we did not have access to the laser therapy in our department. The diode laser system is an excellent toolfor management of eruption cyst,since it eliminates the need for local anesthesia in most cases Painless character of laser has been attributed to its transitory anesthetic effect due to the blocking of theà nerve conduction in Na/K pump.9 The patient is comfortable, not noticing the sensation of vibration or observing the contact of the laser handpiece with the mucosa.4As of local anesthesia is not used, the possibility of complications, toxicityand allergic reactions are eliminated. The diode laser has bactericidal coagulative effectsalso.Compared with conventional scalpel there is mild bleeding and better visibility of working areawith use of laser.10 In the presented 3 cases, we used scalpel for incising or excising the lesion as we did not have access to the laser therapy in our institution. Conclusion: Eruption cyst requires surgical intervention when they hurt, bleed, are infected, or esthetic problems arise. Treatment has to be performed in order to relive the child from discomfort. Clinical significance: Knowledge about occurrence of eruption cyst among clinicians is very essential to provide the correct diagnosis and treatment.

Tess Of The Durbervilles: Coincidences Lead To Consequences Essay
The belief that the order of things is already decided and that people's lives are determined by this "greater power" is called fate. Many people, called fatalists, believe in this and that they have no power in determining their futures. Despite this, many others believe that coincidence is the only explanation for the way their lives and others turn out. Thomas Hardy portrays chance and coincidence as having very significant roles in "Tess of the d'Urbervilles" continuously. Three such coincidences were quite influential and had large effects on Tess's future. The first being that Tess Durbeyfield's father, discovered that their family came from the oldest, (and at one time) most wealthiest family in England. Another event that occurs by mere chance in Tess's life is when Tess slips a letter of confession underneath both her lover's door and (by accident) the carpet, where he could not see it. The final coincidence would be the death of Tess's father, which not only leaves Tess in a state of deprivation, but also the rest of her family including her mother and six siblings. All of these coincidences had consequences that would change Tess's life,.For the first sixteen years of her life, Tess Durbeyfield and her family lived in a middle-class-like situation in the town of Marlott. Since her father, was a life-holder on the cottage in which they lived, his rank was above the farm laborers. However, John Durbeyfield is not in good health when we meet him and he does not put much interest in working, and instead spends time drinking. Upon returning to his home one evening, Durbeyfield meets a man named Parson Tringham who tells him that the Durbeyfield family is the "lineal representative of the ancient and knightly family of the d'Urbervilles, who . . . came from Normandy with William the Conqueror."(p. 18) This news suddenly changes Durbeyfield's view on his family's lifestyle and he decides that they should be living as their knightly and noble ancestors once did.With this new lifestyle in mind for his family, John's wife, Joan Durbeyfield recalls that a man by the name of d'Urberville lives not far from their home and might be able to help them in their hard times, seeing as how he is kin to them. After the death of their only horse, the Durbeyfield family must do something to sustain themselves, but Mr. Durbeyfield ref... ... comes of this major coincidence in Tess's life, because if her father hadn't died and Angel hadn't returned at just the right moment, she would not have killed Alec and would not have been sentenced to an execution for her crimes.Through each and every one of these coincidences, Tess's life changed quite dramatically. Each event that occurred by complete chance left Tess in a predicament where she was compelled to take control and do something to improve the situation. No matter where she was--in the location of her birthplace, a sheltered little town, or in the comfortable landscape that surrounded the dairy, or even in the harsh scenery of the farm-- Tess always knew where she belonged and what she was meant to do in each place. Every coincidence or occurrence that came along, forced Tess to rethink her situation and draw up the courage that to realize who she was and where she was going. The consequences that came, due to her decisions were all ones that Tess was ready for. Even when sixteen men followed her so that she could be punished for the murder of Alec d'Urberville. "'It is as it should be. . .This happiness could not have lasted. . .I am ready.'" (p.417)

Cypress: Alignment and Hr Strategy
Cypress Semiconductor Qn: Is the Cypress strategy aligned with its HR strategy? Why or why not? Cypress Semiconductorââ¬â¢s strategy mainly focuses on: â⬠¢Winning: Provide the best and does not tolerate losing. oHiring the best people oReward based on meritocracy oMaximizing revenue â⬠¢Innovation oLeading the innovation: best product, lowest pricing. oConstantly improving. Alignment to HR strategy Areas that the Cypress strategy aligns with its HR strategy: 1. Ownership Threats employees like entrepreneurs.Allowing employees to run the business like their own actually gave them empowerment and vested interest to do their personal best for their job. Positive results are treated with high return and recognition. This also in turn ensured maximum revenue and profits for their projects. 2. Career Opportunities Cypress Semiconductor is extremely aggressive to hire the best fit of people for their business. They will go to lengths of hiring the best people and pay them adequate compensation to retain them in the company. 3.Compensation Meritocracy in nature, the compensation scheme maintains that outstanding performers are rewarded, non-performers are eliminated. Stock options were given to performers to instill a sense of ownership in the company and the last 3% are deemed as non-performing and are unacceptable. 4. Hiring The almost military clock-work style in their hiring actions quick and precise. Offering at onset of the interview is an aggressive style in hiring and would probably a unique and effective way to get the people they want.Basically, Cypress is hiring people with the winning mentality, they are more likely to be looking for leaders in the hiring process. They will hire the people who can make quick and tough decisions and the candidates they hire are already pre-selected. The whole process of hiring I feel is indeed indigenous as it is self-eliminating. Survival of the toughest ensured that the best in the industry joined. Areas that the Cypress strategy that does not align with its HR strategy: 1. ââ¬ËKillerââ¬â¢ softwareThis system was in placed to help track and improve performance without the development of a bureaucracy in place. Eventually, the system caused the company to focus its attention to bad performance and eliminates the lower tail distribution, the non performing people. This in itself is bureaucratic and military as it does not have a single tolerance to failure. The increased monitoring under the ââ¬Ëkillerââ¬â¢ software became micro-managing in the whole process of performance measure. 2. Goals system This system was set to allow project driven process, that has speed and agility.And was supposed to help teams solve problems and dissolve conflicts. However the feedbacks were negative rather than constructive and highlights failures more than successes. This may not be useful for their annual staff review. 3. No failure tolerance The tough and intensive work environment created by Cypr ess was not for everyone. The stress faced by employees who do not fit is high. There are no other ways to help and retain these people. This tough and competitive environment contributed to the lack of sensitivity towards employees and customers.

Free Essays on Nullification Crisis
Nullification Crisis In 1828, John C. Calhoun had began the protracted Nullification Crisis by asserting the constitutional right of states to ââ¬Å"nullifyâ⬠national laws that were harmful to their interests. The Nullification Crisis had a major impact on the United States. Congress passed a tariff to protect the northern manufacturers and businessmen. Southerners thought that the industrialization of the north would lead to the downfall of the southern economy. They named the tariff the ââ¬Å"Tariff of Abominations.â⬠Vice-president John C.

Free Essays on Personal Life
As a young adolescent my dad always preached at me about leaving cloths and my personal items around the house. At the time I did not agree with my dad because I thought that I could always just pick up my things later. So when I did not clean up after myself the articles would just pile up. If it sat there long enough I would be punished. After I was punished I would get angry because I didnââ¬â¢t think it was a big deal. As a young child I did not understand that it was wrong not to clean up after myself. I always thought that someone else would get it for me. But then I came to the realization that no one wants to pick up after someone else. So, after a while, my dad thought it was time for me to learn the lesson of picking up after myself. He told me for every item that was mine that was not where it should be, I would be grounded for a day. To teach me this lesson, he also would hide my things. He said they were not in their right place. I finally realized that he was serious, and that I needed to change my behavior. I began picking up after myself, which made life easier for me because now I can find all my belongings. It took less time to find my stuff because I always knew where everything was. I also felt a sense of responsibility. An added benefit of my new found behavior was that life was also easier for my family because my stuff was not always in their way. My dad and I got along much better after I started taking responsibility for myself. Now, as a young adult I am happy that my dad made me pick up after myself. His insistence on teaching me this lesson has also taught me self discipline. I use what I learn from this lesson in my life today. One of the ways this lesson has shaped my life is that I now have my own apartment and I often have friends over.

Place-names (linguistics) Essay Example | Topics and Well Written Essays - 2000 words
Place-names (linguistics) - Essay Example Particularly in the case of England, the power of naming becomes a key insight into the history of conquest from foreign powers that the island has experienced in its long life. These conquerors understood the act of naming as the linguistic equivalent of driving a flag into the soil of the vanquished foeââ¬â¢s garden ââ¬â a means of solidifying and extending the message of their invasion and subsequent occupation throughout time. Such is the power expressed through names and naming processes. As Rose-Redwood, Alderman and Azaryahu (2010, p. 454) note, ââ¬Å"the naming of places is one of the primary means of attempting to construct clearly demarcated spatial identitiesâ⬠. For the purpose of the following essay, these spatial identities are to be thought of as political identities as well. ââ¬Å"As a place-name becomes opaque and the original meaning is lost over time, the name comes to feel like a word, in that it feels like an arbitrary combination of sounds used to r efer to a certain item or ideaâ⬠(Radding & Western 2010, p. 396). The same is true of a conquering force, as this essay will demonstrate. This essay argues that the study of place-names requires ââ¬Å"a critical analysis of the social and political struggles over spatial inscription and related toponymic practicesâ⬠(Rose-Redwood et al. 2010, p. 455). As such, the study of place-names becomes more informative about the past ââ¬â about the role that naming played in the military, social and cultural history of England. However, what this essay will also demonstrate is that the social and political act of spatial inscription and place-naming still occurs in the present day, and still functions as a highly effective method for a conquering power to secure its presence over the emotional and psychological space of the invaded populace. This essay will compare the Norman Invasion of England of 1066 with the United States invasion of Iraq in 2003 to illustrate how the topo nymic practices continue to serve key political functions. Despite the thousand year gap between these two military campaigns, the core activity remains the same ââ¬â rename the conquered space using conqueror language in order to cement physical power with linguistic power. This essay will also show how place-naming served a crucial political function even after the use of maps as a means of demarking political territory became widespread. Linguistic and toponymic practices have been used by invaders not only to stake a claim in the conquered lands and to demonstrate their ownership literally, the power of naming extends that power across the centuries, simply because the town or village will adopt the name, people will continue to use the name over and over, and as time passes, the name becomes part of the cultural vernacular and assimilates into the new order. As Radding & Western (2010, p. 395) explain, ââ¬Å"names are given intentionally, to impart a certain meaning. They can be the converse of arbitrary. Yet, over time, people can fail to remember the original, specifically intended meaning and attribute other onesâ⬠. In addition, the act of saying the name repeatedly, over many centuries, continues to assert the dominance of the original source of the name. Thus the individual or group that claims the place via the name also lays claim to the psychological, social and cultural space of the invaded peoples, by leveraging the insidious and viral nature of language itself. As Rose-Redwood et al. (2010 p. 454) note, ââ¬Å"

Analytical Reseach paper on IDS systems SNORT Vs Bro Research
Analytical Reseach on IDS systems SNORT Vs Bro - Research Paper Example Intrusion detection can be carried out automatically as well as manually (Sundaram, 1996). At the present, there exist a large number of intrusion detection systems (IDS). Some intrusion detection systems are available in the open source environment, which make it easier for the organizations to adopt them according to their needs. The basic objective of this research is to provide an analysis of two open source intrusion detection systems: Snort and Bro. The structure of this paper is as follows: first of all an overview of the intrusion detection system is provided, next two sections present an overview of the two IDS systems and after that a comparison of these two IDSs is presented. Basically, an intrusion detection system is an application or device utilized to scrutinize the entire network traffic and notify the administrator or user when there has been an illegal effort or access. There are two major techniques of network traffic monitoring, one is anomaly-based and other is signature-based. Relying on the application or device utilized the intrusion detection system that would be able to either simply observe the administrator or user or it could be placed up to automatically respond in some way or block specific traffic (Bradley, 2015). In this scenario, anomaly based detection in the IDS that compares present network traffic to a known-good baseline to appear for something out of the normal. The intrusion detection system can be placed deliberately on the communication network as a network based intrusion detection or NIDS. This NIDS scrutinizes the entire communication network traffic. It can be installed on every individual communication system like a h ost-based intrusion detection or HIDS that scrutinizes traffic to as well as from that specific device (Bradley, 2015). Martin Roesch developed a NIDS (network intrusion detection system), which is mainly an open source NIDS, and called as Snort. It is basically a packet sniffer, which is
