ABSTRACT:Background: CH materials have also been used for retrograde root fillings and as root canal sealers. However, since most CH hydroxide materials are soluble and can dissolve in the presence of tissue fluids, they have not been a permanent solution for some of these clinical applications.
Aim of the study: To study the effect of calcium hydroxide as a root canal dressing material on dentin microtensile fracture strength in primary teeth.
Materials and Methods: The present study was conducted in the Department of pedodontics of the dental institution. The present study comprised of 80 human maxillary primary incisor. Teeth were divided into two experimental groups. 20 teeth with root canals packed with pure calcium hydroxide mixed with saline were divided into group I, II and group III. The teeth were then immersed in saline at room temperature for 7 (group I), 30 (group II) and 90 days (group III).
Results: Each group had 20 teeth each. The mean microtensile fracture strength in group 1 was 29.9 MPa, in group 2 was 24.9 MPA, in group 3 was 18.6 MPA and in group 4 was 35.3 MPa. The difference was statistically significant.
Conclusion: Within the limitations of the present study, it can be concluded that calcium hydroxide placed in root canals for a long period of time has a negative effect on the dentin microtensile fracture strength in primary teeth.
