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.

Treating Oral Fungal Infection

  Dangers of Oral Fungal InfectionThe appearance of non-candidal oral fungal infections should be concerning, as the majority of these are caused by existing paranasal fungal infections (Scully, 2017b).    By the time these infections are noticed in the oral cavity, it is likely that significant damage has already occurred in other tissues. This requires the use of systemic antifungals such as fluconazole or ketoconazole.    Typically, following the identification of a non-candidal oral fungal infection, the patient should be referred to a physician or specialist, as surgical debridement may be required, and the integrity of the bone surrounding the nasal chambers will need to be evaluated.   Treatment of Fungal Infections   An alternative, aggressive treatment for deep fungal infections in the oral chamber and surrounding tissue is amphotericin B which can be used in conjunction with flucytosine and rifampin for infections that do not respond to amphotericin B a

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 significant destruction of gingival tissue and neighboring alveola

Treatment of Necrotizing Ulcerative Periodontitis

 Treatment options for necrotizing ulcerative periodontitis are highly dependent on the extent of periodontal damage or another concurrent periodontal disease.       Removal of The Affected Teeth Existing periodontal disease with osseous defects prior to the onset of necrotizing ulcerative periodontitis is likely to require removal of the affected teeth (Rutgers, 2017). Pain is a common symptom of this disease and a prescription of analgesia is recommended. Patients may require liquid nutritional supplementation as chewing can be intolerable. Use of Antiseptic Mouth Rinses Antiseptic mouth rinses such as chlorohexidine gluconate can help reduce the population of pathogenic bacteria within the oral cavity itself (Rutgers, 2017). The established antibiotic treatment involves a seven to ten-day course of 1000mg metronidazole broken up into smaller doses either twice or four times daily (Patton, 2016). Metronidazole is not always tolerated by individuals. In these situations, a four-time d
