This study was conducted to observe the response of dog's dental pulp to hydrpxylapatite (Hap) and calcium hydroxide when used as pulp capping materials. After the pulps of 22 teeth were exposed, they were capped with either Hap or calcium hydroxide. Histological analysis was performed 8 weeks after treatment. Results showed that pulp exposure caused irreversible injury of odontoblasts, which w...

The purpose of this study was to evaluate the antibacterial efficacy of an intracanal medication composed of calcium hydroxide with 2% chlorhexidine. Dentin from 24 bovine incisors was used. The incisors were made into standardized cylindrical segments of dentin and infected with Enterococcus faecalis. They were then treated with an intracanal paste composed of calcium hydroxide and sterile wat...

REVIEW ARTICLE: Calcium hydroxide has been used in endodontology for many years. The aim of this paper is to review the various formulations of calcium hydroxide that have been described, with specific reference to the vehicle used to carry the compound. The requirements for a vehicle are described, and ex vivo and in vivo studies reviewed. Vehicles can be classified into aqueous, viscous and o...

introduction: apexogenesis is a way to save vitality of open apex damaged teeth with mild or moderate pulp involvement. such teeth are not repaired through normal and usual treatments. this treatment provides usual and physiological conditions for root to develop in normal length. the aim of this study was to determine the success rate of apexogenesis according to the duration of pulp exposure....

background intra canal medicaments are used to reduce the number of bacteria and reinfection in endodontic procedures. calcium hydroxide was introduced to endodontics by herman as an intracanal antimicrobial agent. objectives the aim of this study was to present an injectable formulation of calcium hydroxide then compare the final ph of this new formulation with metapaste and evaluate the effec...

Background and aims. Since intracanal medicaments can affect the cell viability in periapical tissues, the aim of this study was to evaluate the effect of calcium hydroxide and propolis on pulp fibroblasts. Materials and methods. Two healthy third molars were used as a source to obtain fibroblasts. The fibroblasts were cultured and subjected to 1 mg/mL of propolis and calcium hydroxide. This ex...

The present work investigates the use of magnesium hydroxide, produced by magnesia hydration, as a fire retardant in polymers. The hydration was carried out in an autoclave, at temperature of 130°C for 1 hour, and the product was further submitted to cominution in a jet mill. The solids were characterized with regard to their chemical composition, particle size distribution, surface area and mo...

Studies were carried out by the grapevine berries sprayed with copper hydroxide (Kocide 3000) to assess its quality in terms of reducing sugars, non reducing sugars, total sugars and acidity. The total, reducing and non reducing sugars were higher in the grapevine berries sprayed with Copper hydroxide comparing with that of control plots. Fruit quality was improved in Copper hydroxide (Kocide 3...
