Purpose: To evaluate the effectiveness of decompression as the primary treatment of odontogenic cystic lesions of the jaw involving factors that affect relative shrinking speed and bone regeneration.
Patients and Methods: A total of 32 patients with odontogenic cystic lesions of the jaw underwent decompression with customized thermoplastic resin stents. Clinical examinations and pre- and postdecompression panoramic radiographs were analyzed.
Results: The mean relative speed of shrinkage of radicular cysts (RCs; 3.37 cm(2)/month) was faster than those of keratocystic odontogenic tumors (KCOTs; 2.87 cm(2)/month) and unicystic ameloblastomas (UABs; 2.71 cm(2)/month). The relative shrinking size increased linearly in a time- dependent manner for KCOTs (r = 0.849, P <.001), RCs (r = 0.681, P =.319), and UABs (r = 0.146, P =.730); a similar relation was detected between the primary radiolucent area of cystic lesions before decompression and relative shrinking speed after decompression in KCOTs (r = 0.481, P =.032), RCs (r = 0.260, P =.673), and UABs (r = 0.370, P =.366), but patient age did not affect the relative speed of shrinkage (P >.05). Furthermore, the increase in bone density was more significant in RCs than in KCOTs (P =.026) and UABs (P =.012) after decompression.
