Bottom Line: However, there was a statistically meaningful relationship between the initial size of the lesion and the absolute velocity of shrinkage in the DC group (P=0.02, R=0.65) and the KTOC group (P=0.02, R=0.56).There was also a significant relationship between the age of the patient and the absolute velocity of shrinkage in the KTOC group (P=0.04, R=0.45) and the UA group (P=0.04, R=0.46).However, the age of the patient and the initial size of the lesion showed a significant relationship with the velocity of shrinkage.

ABSTRACT

Objectives: The aim of this study was to verify the clinical effectiveness of decompression in decreasing the size of a cyst. In addition to the different types of cysts, we tried to reveal what effect host factors, such as the initial size of the lesion and the age of the patient, have on the velocity of cyst shrinkage.

Materials and methods: With the aid of a panoramic view, we measured the size of the cysts before and after decompression in 13 dentigerous cysts (DCs), 14 keratocystic odontogenic tumors (KTOCs), and 5 unicystic ameloblastoma (UA) cases. The velocity of shrinkage in the three cystic groups was calculated. Relationships between the age of the patient, the initial size of the cyst, and the shrinkage velocity were investigated.

Results: The three types of cysts showed no inter-type differences in their velocity of shrinkage. However, there was a statistically meaningful relationship between the initial size of the lesion and the absolute velocity of shrinkage in the DC group (P=0.02, R=0.65) and the KTOC group (P=0.02, R=0.56). There was also a significant relationship between the age of the patient and the absolute velocity of shrinkage in the KTOC group (P=0.04, R=0.45) and the UA group (P=0.04, R=0.46).

Conclusion: There was no difference in the decrease in size due to decompression among the different types of cysts. However, the age of the patient and the initial size of the lesion showed a significant relationship with the velocity of shrinkage.

Mentions: In the DC group, the initial mean size of the lesion and the standard deviation (SD) in the panoramic view were 1,474.3 mm2 and 930.7 mm2. The decompression lasted for 6.9 months and a 39.4% reduction was obtained during the procedure. The mean decrement of the lesions was 580.9 mm2. The relative velocity of shrinkage (mean±SD) was 6.1±2.9%/mo and the absolute velocity of shrinkage was 81.1±40.0 mm2/mo. In the KTOC group, the initial mean size of the lesion (mean± SD) was 2,356.3±1,135.7 mm2 and the decompression was performed for 7.4 months. After decompression, we found a 33.6% reduction in the size of the lesion. The mean decrement of the lesions was 791.7 mm2. The relative velocity of shrinkage (mean±SD) was 4.7±2.9%/mo and the absolute velocity of shrinkage was 106.0±81.9 mm2/mo. In the UA group, the initial mean size of the lesion (mean±SD) was 2,115.4±888.9 mm2 in the panoramic view. After 13.4 months of decompression, a 36.7% reduction was found. The mean decrement of the lesions was 776.4 mm2. The relative velocity of shrinkage (mean±SD) was 4.6±5.6%/mo and the absolute velocity of shrinkage (mean±SD) was 115.8±112.9 mm2/mo.(Table 1) No statistically significant inter-group difference was found in the absolute or relative velocities of shrinkage.(Fig. 2)
