impact of genetic disorder on periodontal health

If the results showed negative PAG the patient produced less IL-1 and was less susceptible to periodontitis (Hassell & O`Hehir, nd). Segregation and linkage analysis are noted as forms of scientific studies that look into the Mendelian mode of inheritance to determine if genetic traits of periodontitis exist. Getting young kids to brush their teeth properly can be a battle. Similarly, a report described epigenetics as "changes in patterns of gene expression which do not involve changes in the DNA sequence” (Gomez, Dutra, & Moreira, 2009, pp. Epigenetics, an environmental exposure, chemically changed the expression of DNA transcription. "When I was in college studying my prerequisites to get into the dental hygiene program, I became a chain-smoking, coffee-drinking, fast food junkie," says Annamarie Pamphilis. Megen Elliott gives five tips to stay focused. 625). The dental practice needs to include salivary testing as part of routine dental diagnosis. These factors (if experienced while conceiving or in utero) alter the same genes of one's offspring, thus making an epigenetic change in DNA heritable or transmissible (Yehuda &Bierer, 2009). Acetylation creates a less compact DNA complex that allows for gene expression. Over the years, this model was given considerable support from the scientific community, and it has been the driving force for many clinical treatment decisions. In many cases, dental disease causes a cat to stop eating, which leads to a variety of health problems. A gene is reported as the instructional portion of DNA that signals biological activity within our cells. Studying for the dental hygiene boards doesn’t have to fill you with anxiety if you prepare yourself with these five tips. Complex genetic diseases (polygenic disorders) are the result of altering more than one gene loci and are not known to follow the Mendelian mode of inheritance. 3. This suppression is seen within specific tissues, where inheritance came from one parent or the other, as well as differences within an organ itself. Familial studies conducted in Germany were reviewed by Hassell and Harris (1995) and concluded, “This aggregation within families strongly suggests a genetic predisposition” (Kinane & Hart, 2003, pp 435). It was learned that children from the same parents had different traits which were inherited when genes that resided in their parents’ chromosomes underwent meiosis. It was learned that through (de)methylation or (de)acetylation such changes occurred. This will elicit behavioral changes in both clinicians and the patients they treat. This fact derives from the complexity of the disease, the continuous emergence of new knowledge about its pathogenesis, the relative contributions of a myriad of microorganisms to its etiology, and the vagueness of clinical diagnosis and statistical quantification. Epigenetic factors show increased severity of periodontitis, an inflammatory disease over those who were absent of these factors (Wilson, 2008). The test was performed on each patient who visited the dental office and who appeared to have healthy periodontal tissue. Some patients have abundant plaque and little or no disease; other patients have only a small amount of plaque, but suffer severe disease. Epigenetic effects from nutrition are seen in folic acid deficiency as well as deficiencies in selenium, arsenic, and polyphenols. The Center for Systemic and Oral Diseases reported that there were significant differences in response to therapy between patients with similar clinical exams. The twin model for studying periodontal disease susceptibility has been used very little thus far. A genetic disorder is a disease that is caused by a change or mutation in an individual’s DNA. These type of expressions are site specific, reversible, and are termed epigenetic regulation (Yehuda & Bierer, 2009). Following Waddington, many scientists discussed epigenetics; the material was reviewed by scientist Haig defining epigenetics as "observations that were not easily interpreted in genetic terms but had a heritable component, were liable to be labeled epigentic" (Holliday, 2006, pp. Polymorphisms taken from genes of the IL-1 were tested for the relationship they had with generalized aggressive periodontitis (GAP). Some mutations work better than the original, and many make no difference at all. Tonya Rebhahn, RDH, writes about her chronic illness journey involving Ehlers-Danlos syndrome (EDS). Even people who are highly prone to periodontal disease because of their genetic make-up can prevent or control the disease with good oral care. In post-war Bonn, Germany, periodontal disease was studied by means of the "human twin paradigm," which had been employed for clinical research in medicine and psychology since 1876. Unfortunately, there are no studies directly linked to periodontitis (Gomez, Dutra, & Moreira, 2009, pp. Twin similarity for clinical measures of periodontal disease and for potential host-risk factors for periodontal disease has recently been assessed. (2009). In contrast, deacetylation creates a more compact DNA complex that suppresses gene expression. That is to say, clinical and biological evaluations can tell the dentist and dental hygienist about the current status of the patient`s periodontium, but these signs, symptoms, and clinical judgments have very weak prognostic value. Periodontal disease increases with age; 70.1% of adults 65 years and older have periodontal disease” (CDC, 2015). In-vitro investigations of alveolar bone cells - called osteoblasts - provided breakthrough information about the roles played by various byproducts of microorganisms in the initiation of bone resorption. Many hygienists may react defensively and believe that a patient is implying he or she won’t accept treatment if it’s not at least partially covered. Through these epigenetic factors—primarily diet and aging followed by smoking, diabetes, gender, BMI, race and education—an individual's predisposition for immune or inflammatory response is determined. Vulnerability to periodontitis is increased when IL-1 gene polymorphisms occur and increase the levels of IL-1. Annamarie Pamphilis, ND, MH, BSDH, RDH, RMT, CHC, Realistic tips to help you prepare for boards. For instance, nucleotide adenine (A) could have been replaced with the nucleotide Guanine (G) (Genetic Home Reference, 2015). Nutrition is reported as a factor that could be passed on from generation to generation through in utero exposure or through exposure from parental habits. It was important to note that this does not change the DNA. playing a significant role in whether the trait "alveolar bone loss" is expressed or not. As an example of this phenomenon, let`s consider tobacco smoke and lung cancer. Those changes are very rare and not presented in many individuals (mutation). The first exploration of this hypothesis evaluated the response of gingival fibroblasts from twins to the anti-epileptic drug, phenytoin (Dilantin). In addition, Gomez, Dutra, & Moreira (2009) reported in preliminary studies that hypomethylation of IL-6 gene was found in people with periodontal disease. DNA methylation is noted as chemical reactions that add a methyl group to a DNA molecule (hypermethylation) and demethylation (hypomethylation) as the removal of a methyl group from DNA (Yehuda & Bierer, 2009). Epigenetics was defined as environmental factors that altered gene expression in intergenerational terms. Genetics and Susceptibility to Periodontitis. An RDH's doctor wants her to scale on an 8–10 mm pocket. Effect of gene polymorphisms on periodontal diseases. Genetics — Researchers believe up to 30% of the population may have a genetic susceptibility to periodontal disease. There are chromosome regions that potentially harbor susceptibility genes for periodontal diseases. It is hoped by the authors that through the introduction of chairside salivary testing, periodontitis susceptibility could be reduced and a personalized care plan could be implemented. Some mutations cause problems. Epigenetic change in E-cadherin and COX-2 to predict chronic periodontitis. The two biggest and most common epigenetic factors are nutrition and aging. Since 1960, numerous authors have studied the effects of putative periodontal-pathogenic microorganisms and their byproducts upon human cells in culture. presence of qualitative or quantitative cellular immune alterations, periodontal disease may manifest early on a severe localized or generalized basis--in some cases related to the presence of plaque and/or specific bacteria (severe congenital neutropenia or infantile genetic agranulocytosis, Chediak-Higiashi One quarter of chronic periodontitis patients tested for hyper/hypo methylation proved to be a significant factor in response to inflammatory disease. Viewed globally, the oral-health care professions face only two adversaries: dental caries and periodontal disease. Periodontal disease is a polymicrobial in origin which is highly governed by host response, environmental factors, and genetic factors. This condition causes teeth to be unusually small, discolored, pitted or grooved, and prone to rapid wear and breakage with early tooth decay and loss. Periodontal diseases include a group of inflammatory diseases characterized by progressive destruction of the periodontium. Since 1984, dental researchers in Minnesota also have studied twins reared apart. Genetics is “the study of inheritance and inheritable traits as expressed in an organism’s genetic material” (Bauman, 2014). If the results showed positive PAG it meant that the patient produced more IL-1 and was therefore susceptible to periodontitis. The greater similarity of identical twins - whether reared together or apart - suggests that there is a genetic contribution to variations in levels of supragingival plaque and clinical measures of periodontal health. This appear as patches of certain cells expressed from the mother and in other areas of the same organ cells expressed from the father (Wilson, 2008). To top it off, the state board informed her coworker that RDHs could lose their licenses for failure to provide SRP to perio patients who need it. Blood (finger-stick) or saliva sample was collected and taken to the laboratory to be tested for PAG. Monocytes from patients who are genotype-positive produce more IL-1 when stimulated by bacterial antigen. Thirty years ago, a clinical study of periodontal health in 26 twin pairs aged 12-17 years found no evidence of a genetic contribution to variation in gingival recession, sulcus probing depth, or indices of gingivitis, calculus, and plaque. It was found that these processes were key factors in inflammatory and neoplastic diseases. This is an example of epigenetic regulation. People who have both of these factors are subjected to a dramatic increase in lung cancer. This also will maximize cost-to-benefit equations. Frequency of allele 2 of the IL-1B +3953 SNP proved significant increase in patients with advanced periodontitis” (Tarannum & Faizuddin, 2012, pp 12). Olive Njari and Felicia Hollander are students in the dental hygiene program at Collin College in McKinney, Texas. It is said that there is a strong correlation between gene expression with both histone modification and DNA methylation (Wilson, 2008). Untreated perio and COVID-19: What is the evidence? The biggest factors noted are environmental in nature and changed the phenotype and pathogenicity of each patient. Production of IL-1 is believed to lead to more generalized and severe disease. The good news is that the list of acknowledged and proven periodontal risk factors is relatively short and well-understood. © 2020 Endeavor Business Media, LLC. This permits adding a fifth Orisk factorO to the list: genetic susceptibility due to the IL-1 genotype. She says, “Advocate for yourself, do everything in your power to prevent cumulative trauma to your body, and always be prepared for the situations that may come about over which you have no control. Recent clinical research has demonstrated that the Heritability Estimate for clinical signs of periodontal disease probably ranges between 40 and 80 percent. Epigenetics and periodontal disease: Future perspectives. Ten years later, other scientists were able to explain this phenomenon when they discovered that some people have a genetic ability to convert potential (tobacco-derived) carcinogens into active carcinogens, while other people do not. On the other hand, the genetics of susceptibility to inflammatory periodontal diseases have remained elusive. Over 30 different microorganisms have been identified as putatively pathogenic; thus, some researchers have tried to ascertain the effects of such microorganisms upon cultured cells derived from human oral tissues. It was found that with methylation, demethylation and acetylation, deacetylation or any combination of these worked to either express or repress genes during replication. A condition caused by mutations in one or more genes is called a genetic disorder. However, more recent and well-controlled studies of more appropriately-aged twins support the concept that genetic variation may contribute to individual differences in risk for the more common adult periodontitis. The fraternal twins whether living together or separately showed fewer similarities. Fact: Not all people who smoke develop cancer. Age and gender were taken into account. It is termed juvenile periodontitis, namely the inadequate host response to etiologic substances. In some cases, gene mutations are so severe that they prevent an embryo from surviving until birth.
