Özet:

The main aim of this case report was to report the clinical efficacy of decompression for treating large periapical lesions. Tooth with large periapical cystic lesions were treated with decompression after root canal treatment. A conventional decompression technique such as aspiration/irrigation technique was used in this case. An 18-G needle with a syringe was used to aspirate the cystic lesion. Two needles were then inserted into the lesion copious saline irrigation was delivered from 1 needle and until clear saline was expressed from the other. Complete enucleation and root-end surgery was not done in the case. Healed lesions or lesions in healing were observed after 14 months. On the basis of the presented case and published case reports regarding large periapical cystic lesions, conservative decompression may be used for certain cases before or in lieu of apical surgery. Decompression enables healing of large, persistent periapical lesions after root canal treatment.
