DENTAL SEPSIS.

The research article explores dental sepsis, a common dental issue seen in horses, tracing its causes, development, and potential complications.

Causes of Dental Sepsis in Horses

• The study reveals that dental sepsis in horses typically happens when the pulp chamber of a tooth—the innermost part of the tooth containing the vital tissues—gets exposed to the oral cavity or outside environment. This exposure allows pathogenic bacteria to localize and start an infection in the tooth.
• Several contributing factors may lead to the localization of pathogenic bacteria in the pulp chamber. They include maleruption (abnormal or delayed eruption of teeth) or impaction of teeth (blocked tooth unable to break the gum line), leading to secondary alveolar bone lysis (destruction or dissolution of the jawbones).
• Other causes highlighted in the study include primary fractures of the tooth, mandible (lower jaw), or maxilla (upper jaw), as well as periodontal disease—gum disease that affects the tissues that hold the teeth in place, or infundibular necrosis—death of the infundibular cells due to lack of nutrient supply.

Resulting Conditions from Dental Sepsis

• The research underscores that, in horses, acute, primary, septic pulpitis—ordirect inflammation of the tooth pulp due to bacterial infection—is uncommon. However, dental sepsis often happens due to secondary infection with pathogenic bacteria.
• Once a pulpal infection initiates, it can extend to the surrounding periradicular tissues, which are the tissues surrounding the root of the tooth. This can subsequently lead to the formation of periapical abscesses in the mandibular or maxillary. Periapical abscesses are pockets of pus resultant of a bacterial infection at the tip of a tooth root, in this case, either in the lower or upper jaw of the horse.
