Abstract
Some physical, chemical and biological properties of the periodontal dressing materials with eugenol and without eugenol had been previously reported. Especially, it was considered that the adaptability of the periodontal dressing to the wound surface is an important factor by various investigation.
The purpose of this study was measured to compare the dimensional change of commercially available periodontal dressing materials (Septo-pack, COE-pak [Hard & Fast set]).
After mixing, each paste on glass board was immediately depressed placing a weight on glass board. The expansion of specimens were measured immediately afer preparetion, and soaked in distilled water at 37±0.5°C.
Measurments were made at 30 minutes, 1, 2, 3, 4 hours, 1, 3, 5, 7 and 10 days after.
The results obtained were as follows:
1. Septo-pack showed expansion during the 1-hour after preparetion and continued cotraction in process of times.
The changing value of Septo-pack showed approximatey three times higher than Peripac.
2. COE-pak [Hard & Fast set] continued contraction during in experimental period.
The cotraction state of COE-pak [Hard & Fast set] showed lower about 1.0-6.4% than COE-pak.
