Epstein-Barr Virus

 

Infection with human herpesvirus 4, also known as the Epstein-Barr virus (EBV), causes mononucleosis. 

  • ·  Additionally, in individuals infected with HIV, EBV is capable of facilitating the development of oral hairy leukoplakia (Cade, 2017). 
  • This disease is highly associated with immunosuppression and can occur when HIV progresses to AIDS. Oral hairy leukoplakia consists of the development of nonremovable textured growths on either side of the tongue.
  •  When the EBV replicates within these lesions, the epithelial cells undergo hyperplasia and make the lesions appear hairy. 
  • These growths can be obtrusive and can be treated with antivirals including acyclovir in order to reduce their size. However, the development of hairy leukoplakia on the tongue is an indication of severe immune suppression and is associated with a poor prognosis (Cade, 2017).

Viral infections

 The oral cavity can be targeted by a variety of viral pathogens (Tyring, 2006). While these viral infections are variable in severity, they are more virulent in individuals with compromised immune systems (Regezi, 2016). Viruses are biologically different than bacteria or fungi in that viruses are not capable of replication and proliferation by themselves. A virus particle, or virion, consists of a protective protein coat called a capsid that contains the viral genome.   The viral genome is encoded with either deoxyribonucleic acids (DNA) or ribonucleic acids (RNA), depending on the viral species. The capsid includes proteins that target specific cell types in specific species as well as mechanisms for entering into the target cell types. The host cell’s own protein machinery then replicates the virus’s genetic material and produces the viral proteins required for capsid formation encoded by the virus’s genome. This replicates the virus, allowing more copies to be released to...

Genetic Susceptibility

  Historically, the contribution of genetic factors to an individual’s predisposition for the development of oral infections has been largely unstudied.    In the age of genetic medicine, it is becoming apparent that genetic variability can account for significant changes in innate and adaptive immune responses, with some clear implications for the development of maxillofacial infections (Munz et al., 2017).    One such study identified genetic variation in the genes DEFB1 and LTF that were linked with susceptibility to chronic periodontitis (Zupin et al., 2017). These genes encode the proteins beta-defensins 1 and lactoferrin, both of which contribute to the oral innate immune system.

Gingival Inflammation and Classification | Periodontics

  Inflammation of the gingiva is called gingivitis.   Gingivitis is usually mild and does not cause destruction of the attachment fibers and underlying bone. Untreated gingivitis can progress to serious periodontal diseases. CLASSIFICATION 1) ACCORDING TO DURATION ACUTE GINGIVITIS-  Sudden in onset, Short in duration and Painful in nature. CHRONIC GINGIVITIS-  Slow in onset, Long in duration and Mostly Painless. Most common type of gingivitis. 2) ACCORDING TO DISTRIBUTION LOCALIZED GINGIVITIS- Gingivitis when confined to the gingiva of a single tooth or group of teeth. GENERALIZED GINGIVITIS- Gingivitis which involves the entire gingiva of the mouth. MARGINAL GINGIVITIS- It involves the gingival margin and may include a portion of the contiguous attached gingiva. PAPILLARY GINGIVITIS- Gingivitis which mainly involves the interdental papillae and may extends into the adjacent portion of the gingival margin. DIFFUSE GINGIVITIS- It affects the gingival margi...
