Functional Relationship of Room Temperature and Setting Time of Alginate impression Materail

---

Indonesia is a tropical country with temperature variation. A lot of dental clinics do not use air conditioner. The room temperature influences water temperature for mixing alginate impression material. The aim of this study was to investigate the functional relationship of room temperature and initial setting time of alginate impression materials. The New Kromopan alginate (normal and fast sets) were used. The initial setting time were tested at 23 (control), 24,25,26,27,28,29, 30 and 31 degree Celcius room temperature (n=5). The initial setting time was tested based on ANSI/ADA Specification no. 18(ISO 1563). The alginate powder was mixed with distilled water (23/50 ratio), put in the metal ring mould, and the initial setting time was measured by test rod. Data wre statistically analyzed by linear regressin (α =0.05). The initial setting times were 14960±0.55 (control) and 96.40 ± 0.89 (31⁰C) seconds for normal set, and 122.00 ± 1.00 (control) and 69.60±0.55 (31⁰C) seconds for tast set. The coefficient of determination of room temperature to initial setting time of alginate were R2=0.88 (fast set) The regreassion equation for normal set was Y=257.6-5.5 X (p
