Tratamiento de una lesión endoperiodontal tipo III (combinada o verdadera): reporte de un caso

we report a case of a type iii periodontal-endodontic lesion (combined or true) in a 41-year-old female patient without systemic history. the patient was transferred from the specialization course in periodontology at the graduate school of the university of chile due to a periapical lesion in the tooth 3.6. the prognosis for this type of lesion is uncertain, since it is necessary to perform endodontic and periodontal treatment, and the result depends more on the periodontal treatment. the piece was treated endodontically leaving intracanal medication based on 2% chlorhexidine gel for 7 days. once the tooth obturated, we gave the patient an appointment 3 months later for a control radiography. currently, the tooth is completely asymptomatic, without mobility and with signs of repair.
