A Case Of Non-Surgical Treatment Of Apical Cyst

This article reports the non-surgical treatment of a large apical cyst in an adult patient. The patient had suffered from recurrent swelling and pain for more than two years. Root canal treatment had been done in another hospital previously, yet there was no obvious alleviation, and surgical treatment was suggested. A CT scan revealed a low - density shadow in the periapical regions of teeth 14, 15 and 16, which was 27.5 mm in length and 22.53 mm in height. A complete root canal treatment was carried out. After three follow - up visits, the patient's symptoms disappeared and there was no exudate in the root canal. After root canal filling, the patient made regular follow - up visits. Four years later, during the re - examination, the patient was asymptomatic. The CT scan showed that the periapical shadow had become smaller, with a length of 13.01 mm and a height of 12.27 mm. The patient was advised to continue the observation. Traditional treatment methods for apical cysts mainly involve surgical enucleation. In this case, non - surgical treatment achieved a satisfactory outcome. Analyzing the reasons for the success of this treatment, it might be related to thorough root canal cleaning, disinfection, and continuous drainage for decompression. Although the evaluation period has to be longer, the intervention of major surgery has been avoided. The size of the periapical shadow is not a decisive factor for determining surgical treatment.
