Introduction:

The odontogenic keratocystic (OK) is considered nowadays as a benign odontogenic tumor. Nevertheless, it has an aggressive nature due mainly to its local expansive potential and its high recurrence rate. Currently, there are different therapeutic approaches that are directly related to the recurrence rates of this type of tumor.

Objective:

The objective of this study is to analyze the recurrence rates of the different treatment modalities of the OK.

Material and method:

Following PRISMA recommendations, it was perfomed a systematic review in different databases analyzing the recurrence rates of different therapeutic options of the OK.

Results:

The average percentage of recurrence of the 11 articles reviewed was of 26,8 %, being resection the treatment with lower recurrence rates (0 %) and marsupialization the treatment with the highest percentage of recurrence (45,8 %).

Discussion:

Recurrence is directly related to the possibility that parts of the epithelium may remain in the cavity after treatment. Therefore, resection is the treatment with the least recurrence. However, the aggressiveness of this therapeutic modality is not justified in all cases. There are other very effective variants such as enucleation either alone or in combination with adjuvant therapies such as Carnoy's solution application.

Conclusions:

Resective treatment has the lowest recurrence rates although it is considered that the OK can be approached in a more conservative way due to its benign nature.
