| Summary: | Calcium hydroxide (Ca(OH)�) is one of the ingredients that are very effective as intracanal medicaments because it has a beneficial biological properties, but there are studies which indicate that direct contact of calcium hydroxide to dentine root canal, influences the change in the physical properties of dentine. This study aimed to determine the effect of calcium hydroxide as an intracanal medicament with the vehicles of saline, chlorhexidine digluconat 2% and lidocaine HCL 2% to dentine microhardness at two-thirds of the of root canal dentine cervical segment.
Thirty extracted mandibular first premolars were used in this study. The crowns of the teeth were removed and the canals were prepared by using a crown-down technique. Each root was further transversely on cervical two-thirds a thickness of 4 mm and they were mounted on acrylic resin. The specimens were divided into six groups, according to the type of mixed material how long the contact. In group IA and IB, pasta of Ca(OH)� was saline applied for 7 days and 14 days. In groups IIA and IIB, pasta of Ca(OH)� + 2% chlorhexidine digluconate applied for 7 days and 14 days. Groups IIIA and IIIB, pasta of Ca(OH)� lidocaine HCL 2% was applied for 7 days and 14 days. During the treatment period, the speciments were kept in a 37 ° C incubator. Vickers Indenter Microhardness Tester was used to measure the micro hardness of root canal dentine after direct contact with Ca(OH)� paste. Data were analysed using the 2 way Anova continued with LSD test
The results showed that there were significant effects of calcium hydroxide as an intracanal medicament the vehicles of saline, chlorhexidine digluconat 2% and lidocaine HCL 2% to dentine microhardness at two-thirds of the root canal dentine cervical segment. |
