[[Intra-Oral Radiography - Small Animal|Radiographs]] may provide information about the presence, nature, and severity of periapical and [[Enamel Organ#Root|root]] pathology. This information is essential for the diagnosis of [[Endodontic Conditions|endodontic disease]] as well as for the prognosis of its treatment. Radiographs do not provide direct information about [[Enamel Organ#Pulp|pulp]] health; however, many of the effects of pulp pathology are radiographically visible.<br><br>

Clinical findings that may indicate the presence of endodontic disease include a fractured [[:Category:Teeth - Anatomy & Physiology|tooth]] with exposure of the pulp chamber, a discolored tooth, or an intraoral or extraoral draining fistula. Except in the obvious case of a direct pulp exposure, a definitive diagnosis of endodontic pathology is difficult to make based only on [[Oral Examination - Small Animal|clinical examination]] of veterinary patients due to the limitations of pulp testing and lack of patient input. <br><br>

Inflammation caused by endodontic disease affects the surrounding bone and teeth, resulting in changes that can be radiographically detected. Radiographs that are meant to evaluate the periapical tissues should include the entire [[Enamel Organ#Root|root]] tip and surrounding bone, be well positioned to avoid elongation, foreshortening, angulation, or distortion of the image. <br><br>

*Arrested tooth maturation (pulp necrosis). Pulp necrosis causes the opposite effect, arresting any further [[Enamel Organ#Dentin|dentin]] formation or tooth maturation. The result is a tooth that appears radiographically less mature (wider root canal space) than the adjacent teeth.

*Accelerated apparent tooth maturation (pulpitis). Pulpitis can also result in formation of tertiary, or reparative dentin on the walls of the pulp cavity. Pulpitis that is generalized over a section of a root canal creates the radiographic effect of a narrower canal in that section, giving the appearance of a more mature tooth. The extreme of this can manifest as “pulp cavity obliteration,” a radiographic term that describes an inability to identify sections of, or the entire, pulp space.
