LEON, P; ILABACA, MJ; ALCOTA, M  y  GONZALEZ, FE. Frequency of apical periodontitis in endodontic treatment in undergraduate. Rev. Clin. Periodoncia Implantol. Rehabil. Oral [online]. 2011, vol.4, n.3, pp.126-129. ISSN 0719-0107.

Apical periodontitis is a microbially induced inflammatory disease of the periapical tissues. Its treatment requires eliminating microorganism from root canal and sealing it properly to induce further tissue repair. The aim of this study was to determine the frequency of apical periodontitis and its distribution by gender, age, range, acute vs. chronic, treatment success and rehabilitation in the population attended at the undergraduate clinic of Endodontic at the Faculty of Dentistry, Universidad de Chile. Information was collected from 292 teeth of patients treated at the clinic, recording data of those with teeth diagnosed with some type of apical periodontitis and related to different variables: specific diagnosis, age, gender, acute vs. chronic, successful or failed treatment and post-treatment restoration. The frequency of apical periodontitis was 36.7% (92 patients). 77.8% of the teeth with apical periodontitis had a chronic disease. 75% of the patients were female. The 5th decade represented a 34.8%. There was a 100% success rate in their treatments, while the most common restoration was the composite (52.4%). The low number of patients who responded to the dental revision to determine the success of the treatment, despite the 100 % rate, cannot be evaluated as a significant result. Our data showed that the most frequent condition was chronic apical periodontitis, affecting more female patients, and the 5th decade and incisors.
