Varicella-Zoster Virus

 

The Varicella-Zoster virus (VZV) is another name for human herpesvirus 3, which causes chickenpox. After chickenpox blisters heal, VZV can remain dormant in neurons for decades. 

  • ·  Recurrence of VZV from the dormant virus is the cause of shingles. While shingles can occur at any time, aging and impairment of the immune system are factors that promote its reactivation. 
  • The lesions that characterize shingles can occur anywhere on the skin and do not present any specific complications to oral health. 
  • Being aware of the presence of these blisters in the oral or maxillofacial region is advisable, as they can be extremely painful and cause additional discomfort for individuals undergoing dental procedures. 
  • As with other viral infections, weakened immune systems are a precipitating factor for the reactivation of VZV and therefore the presence of shingles should prompt inquiry into the patient’s immune function.

Irreversible Pulpitis- Symptoms, Diagnosis and Treatment

  Definition Irreversible pulpitis is a persistent inflammatory condition of the pulp, symptomatic or asymptomatic in nature with the pulp becoming incapable of healing. Types There are two types of Irreversible Pulpitis 1) Asymptomatic Irreversible Pulpitis 2) Symptomatic Irreversible Pulpitis Causes/Etiology CAUSES/ETIOLOGY  Most common is Dental Caries Chemical, Mechanical and Thermal injuries to pulp Untreated reversible pulpitis Symptoms SYMPTOMS Pain is caused by sudden change in temperature specially cold, sweet or acidic food items and pressure from food entrapped in tooth cavity Pain remains even after the removal of stimulus. Pain can be spontaneous which can be Sharp, Piercing, Intermittent or Continuous in nature Pain exacerbated by lying down or on bending due to increase in intr...

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.

Infections in Immunocompromised Patients

  ·   Gingivitis normally has a slow progression toward periodontal disease with increasingly obvious symptoms as the disease worsens. However, people with immune system impairments have more rapid development of periodontal disease. ·   Causes of Periodontal Disease The microbial causes of periodontal disease in immunocompromised patients are the same as in individuals with normal immune systems (Tyring, 2006).   In individuals infected with HIV, if the level of T-helper cells falls too low and AIDS develops, the likelihood of infection from even normally benign microorganisms increases (Prevention, 2017). Effects of Periodontal Disease ·          Gingival tissues specifically are likely targets for opportunistic infections due to the diverse population of bacteria, fungi, and viral particles normally in their environment. In these patients an infection can take root quickly, resulting in si...
