The Formation of Hyphae

       Function of Hyphae
After the fungal cells are firmly established on the oral epithelium they generate tubular structures called hyphae. These hyphal lattice structures act as physical barriers to prevent host macrophages from phagocytosing the fungal cells.

The development of hyphae also begins to link fungal cells together into multicellular syncytia. When C. albicans becomes entrenched in this manner, it can excrete enzymes like aspartyl proteinases and phospholipase. These enzymes can break down cell membranes and the extracellular matrix of the epithelial tissues in proximity to the fungus.
Effects on Individuals with compromised Immne Systems
As surrounding tissues are damaged, the fungi can penetrate deeper into the oral mucosa and affect many tissue types. In individuals with compromised immune systems, this fungal incursion can cause serious medical complications and can be fatal. The host immune response is able to respond differentially to C. albicans depending on whether the fungi are behaving commensally or if it acting virulently.
How neutrophilis counteract fungi before they cause Additional Changes
Tissue damage caused by virulent C. albicans releases the inflammatory signaling molecules called alarmins that recruit neutrophils to the site of injury and begin to counteract the fungi before they cause additional damage. This point underscores the importance of a competent immune system in preventing these fungal infections from reaching dangerous levels (Schonherr et al., 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...

Internal Resorption (Pink Tooth of Mummery)

  Definition it is an idiopathic slow or fast progressive resorptive process occurring in dentin of the pulp chamber or root canals of teeth.  It is known as pink tooth of mummery due to its pinking discoloration of crown and named after anatomist Mummery.  First Reported by Bell in 1830. Causes/ Etiology Not Known, but generally patients have history of trauma. Histopathology It is a result of the osteoclastic activity. Resorptive process is characterised by lacunae which may be filled by osteoid tissue Osteoid tissue may be regarded as attempt of repair. Symptoms Asymptomatic  Pain occurs if resorption perforates the root.  Pink tooth is pathognomonic feature.  Pulp shows either partial or complete necrosis.  In crown may be manifested as a reddish area called “Pink Spot” which is due to granulation tisue showing throgh resorbed area.  Diagnosis Clinically - Pink Tooth appearance. Radiographic Changes- -Well defined radiolucency of uniform den...

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.
