Malignant Neoplasms of Oral Mucosa

 

Malignant tumors of the oral mucosa are persistent and progressive. They may metastasize to nearby lymph nodes. It is important to note that breast, kidney, lung, and bone cancers may metastasize to the oral cavity.·  Squamous Cell Carcinoma

- This is the most common malignant tumor of the oral cavity. It is associated with alcohol and tobacco use. 

- It can occur anywhere in the oral mucosa. It rarely causes symptoms.

Verrucous Carcinoma

- This slowly-growing tumor has a rough, warty surface and rarely causes symptoms. 

- It may invade connective tissue but rarely metastasizes.

Salivary Gland Adenocarcinoma

- This is a grouping of polymorphous low-grade adenocarcinoma, adenoid, acinic cell, mucoepidermoid, pleomorphic adenoma, and other cancerous lesions. They have varied clinical presentations. 

- They all infiltrate other tissues.

Kymphomas

- These cancers of lymphocytes are subdivided into Hodgkin or non-Hodgkin types. The non-Hodgkin lymphomas more commonly cause oral mucosal lesions. 

- They also cause lymph node lesions that are non-tender.

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.

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...

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...
