Abstract

Objective: The use of microwave energy has been used in various fields of dentistry, medicine and household appliances. Recently microwave energy has been successfully used in dentistry and plethora of articles has been published. Also included in the field of sterilization, disinfection of dental appliances, drying of gypsum product and polymerization of resin. The objective of this study was to compare the linear dimensional accuracy of conventional heat cure resin to microwave cure resin. Method: In this study a standard metal die as per ADA specification NO 12 measuring 65 mm in length,3 mm thickness,10 mm wide was used to plan 30 test specimens. 15 test specimens were prepared from conventional heat cure resin and 15 from microwave cured resin. The specimens were checked and evaluated using digital caliper which has precision of ±0.001 mm. The measurements were compared recorded with standard metal dies. Result and conclusion: Linear dimensional accuracy was checked both between and within the group with the ANOVA test and found that accuracy between the groups was 0.148 and 0.004 within the group of the study. Consequently the liner dimensional accuracy of microwave resin were better-quality and advanced to conventional cure resin with p value of 0.000.
