Rationale of Endodontic Treatment

 

The term “Rationale” can be defined as the fundamental reason or the rational basis for a procedure.

The rationale for endodontic therapy is based on the belief that a natural tooth functions more efficiently and comfortably than a bridge, partial denture or an implant tooth.

THEORIES OF SPREAD OF INFECTION

1) FOCAL INFECTION- It is localized or general infection caused by the dissemination of microorganisms or toxic products from a focus of infection.

2) FOCUS OF INFECTION- This refers to a circumscribed area of tissue, which is infected with exogenous pathogenic microorganisms and is usually located near a mucous or cutaneous surface.

PORTALS FOR ENTRY OF MICROORGANISMS

Microorganisms may gain entry into pulp through several routes. Most common portal of entrance for microorganisms to dental pulp is dental caries.

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.
