Abstract

Purpose: The purpose of this study was to evaluate the clinical factors affecting the effectiveness of decompression as the treatment of cystic lesions of the jaw.

Patients and Methods: A total of 45 patients with cystic lesions of the jaw underwent decompression with readymade stents. Clinical examinations and pre- and post-decompression panoramic radiographs were analyzed.

Results: Mean amount of reduction for Radicular cyst (RCs), nasopalatine duct cyst (NPCs), dentigerous cyst (DCs), unicystic ameloblastoma (UABs) were 2.43 cm2 (P = 0.02), 2.04 cm2 (P = 0.043 ), 3.96 cm2 (P = 0.000), and 7.70 cm2 (P = 0.017 ), respectively. There was statistically significant decrease of the cystic size in the each group. Mean relative speed of shrinkage of the 4 types of lesions were 0.38 cm2/month, 0.34 cm2/month, 0.44 cm2/month, and 0.81 cm2/month respectively. There was statistically significant difference among the 4 types of cyst (P=0.001) ; DCs> RCs(p=0.000), DCs> NPCs(p=0.007), UABs> DCs(p=0.011). The primary cystic size of RCs, NPCs, DCs, UABs were 4.19 cm2, 4.48 cm2, 7.20 cm2 and 13.58 cm2,, respectively. Two type of cyst were statistically significant relationship between relative speed of shrinkage and primary cystic size; DCs (p=0.0285) and UABs (p=0.001). The mean age of the patients did not significantly effect on relative speed of shrinkage (p=0.8) and male were significantly faster for relative speed of shrinkage than female (p=0.038). The relative shrinkage speed associated with dental arch was significantly faster in mandible than maxilla (P=0.002).

Conclusions : Decompression can be a good therapeutic choice of treatment of cystic lesion of the jaw when applied selectively. However, the mechanisms that the factors affecting effectiveness of decompression such as sex, age, location of lesion are still not fully understood. Further investigation should be continued.
